Joint Replacement

Total shoulder arthroplasty (TSA) for osteoarthritis with intact cuff vs reverse TSA (rTSA) for cuff arthropathy, complex fractures, and revision.

Overview

Final recommendations derived from literature and expert consensus serve as a primary resource to guide decision-making for stakeholders introducing artificial joint arthroplasty devices [1]. Surgeons must critically examine existing outcome literature for various arthroplasty options to maximize clinical results and ensure revision-free implant survival [3].

In the knee, unicompartmental and bicompartmental arthroplasty using a finned metal tibial-plateau implant is a valid reconstructive option for the arthritic joint when indications are appropriate [6]. For glenohumeral osteoarthritis with an intact rotator cuff, reverse arthroplasty achieves highly favorable outcomes [14]. In the shoulder, procedures for osteonecrosis remain predominantly arthroplasty, though joint-preserving techniques are increasingly utilized, particularly in patients under 50 years of age [10]. Arthrodesis is an efficacious and safe short-term alternative for young patients concerned about arthroplasty [62].

Total joint arthroplasty is safe and provides good functional outcomes in lung transplant recipients [19]. For stemless anatomic total shoulder arthroplasty, age 70 years or older is not a contraindication, as postoperative improvements in patient-determined outcome scores and range of motion are similar to those in patients under 70 [57]. However, outcomes after prior shoulder surgery are clinically improved but inferior compared to patients without such history [58]. Regarding revision replacements, over 80% last 5 years and over 70% last 10 years [4]. Surgical implant type, indication, patient comorbidities, and hospital factors contribute to differential costs for total shoulder arthroplasty [18]. Longer follow-up and prospective randomized comparisons are needed to better define revision, failure, and complication rates for proximal interphalangeal joint prosthetic arthroplasty [20].

Anatomy & Pathophysiology

Kinematics

Combined kinematics are an indispensable part of wear tests on anatomic shoulder replacements [29]. Biomechanical evidence suggests that an elliptical implant yields glenohumeral kinematics that mimic the native joint [32]. In vivo, glenohumeral joint contact after total shoulder arthroplasty is not centered on the glenoid surface [65]. This contact pattern suggests that kinematics may not be governed by ball-in-socket mechanics as traditionally thought [65]. The spherical head shape does not show significant glenohumeral translation during humeral axial rotation, regardless of glenoid conformity [71].

Component Positioning and Biomechanics

Malpositioning of both the humeral and glenoid components adversely affects the range of motion, kinematics, and stability of the shoulder [41]. Anatomical reconstruction of the glenohumeral surfaces is important for the success rate of anatomical total shoulder arthroplasty [77]. Optimal glenohumeral mismatch in cemented pegged glenoid implants is multifactorial and has not been definitively established [79].

Reverse shoulder arthroplasty is a useful tool for treating older patients with B2 glenoid deformities, offering favorable biomechanics [51]. Assessment of patient, biomechanical, and surgical factors is critical in determining the best course of treatment for instability in reverse total shoulder arthroplasty [52]. Most reverse prostheses impingements can be avoided by scapular compensation or by a glenosphere lateralization [63]. Extra-short humeral heads significantly reduce the incidence of glenohumeral joint overstuffing compared with short heads, maintaining more normal shoulder biomechanics [59].

Placement of a distal humeral hemiarthroplasty implant causes a small but significant alteration in elbow joint kinematics, regardless of implant size [78].

Classification

Post-treatment Glenoid: This system addresses the surgical management of the glenoid during total shoulder arthroplasty prosthetic replacement, allowing for direct follow-up comparison of similarly treated glenoid replacements [23].

Glenoid Morphology Clustering: Clustering based on glenoid morphology identifies patterns in defect types, highlighting a need to further investigate a three-dimensional classification system and potentially new standardized revision implant component designs [31].

Prosthetic Joint Infection (PJI) Topography: A new perspective introduces topography as a key factor affecting treatment strategy. Identifying the exact location of bacterial colonization (e.g., joint space vs. bone-prosthetic interface) guides treatment strategy, potentially allowing implant retention where the interface is not invaded and necessitating radical intervention otherwise [42].

Walch: This classification has prognostic value for patients before and after shoulder arthroplasty performed for osteoarthritis with an intact rotator cuff [69]. Alternative glenoid classification systems or predictive models should be considered to provide more precise prognoses than the Walch classification [69].

Clinical Presentation

Joint arthroplasty is dramatically successful in terms of relief of pain and maintenance of variable degrees of improved function [8]. Elective shoulder arthroplasty can be performed in patients 90 years of age and older, providing excellent pain relief, improved functional outcome, and enhanced general health status [38]. Shoulder arthroplasty provides marked long-term relief of pain and improvement in motion; however, nearly half of all young patients who have a shoulder arthroplasty have an unsatisfactory result according to a rating system [39].

A systematic evaluation involving clinical history, physical examination, laboratory tests, and imaging is required to identify potential differential diagnoses in patients with painful non-metal-on-metal total hip arthroplasty [9]. Single-photon emission computed tomography/computed tomography (SPECT/CT) has good clinical application value and should be a primary choice in the diagnosis of aseptic loosening after joint replacement [12].

Dislocation of the polyethylene insert is a rare complication that should be included in the differential diagnosis for patients with sudden onset of mechanical symptoms, effusion, or unexplained pain after total knee arthroplasty [33]. Tumoral calcinosis complicating total joint replacement is rare and should be included in the differential diagnosis for a periprosthetic soft-tissue mass in the setting of chronic hemodialysis [35]. Diagnostic arthroscopy is a useful adjunct in identifying causes of failure in patients with painful reverse total shoulder arthroplasty, especially when the cause of failure is unclear [36].

Investigations

A systematic evaluation involving clinical history, physical examination, laboratory tests, and imaging is required to identify potential differential diagnoses in patients with painful non-metal-on-metal total hip arthroplasty [9].

Plain radiography: Radiographic osteolysis after total shoulder arthroplasty may lead to clinically important complications such as aseptic loosening [107]. Xerograms can confirm the diagnosis of a prosthesis fracture and help localize the positions of fragments within the joint to facilitate surgical removal [98].

CT: Single-photon emission computed tomography/computed tomography (SPECT/CT) has good clinical application value and should be a primary choice in the diagnosis of aseptic loosening after joint replacement [12].

Bone scan: Bone scan uptake after trapeziometacarpal joint arthroplasty progressively decreases over time, with normalization of tracer uptake expected between 14 and 25.5 months after surgery [105].

Treatment

Non-Operative

Non-operative treatments for post-dislocation shoulder osteoarthritis show similar osteoarthritis proportions at any point of follow-up compared to operative management [81]. For rheumatoid arthritis, fully two-thirds of patients respond satisfactorily to non-surgical measures, though surgical treatment has an increasing role in correcting and preventing deformities [95]. In hallux rigidus and first metatarsophalangeal joint osteoarthrosis, selection of non-operative measures versus surgical procedures depends on disease stage and patient factors [88].

Operative

Indications: Joint replacement is indicated for pain relief and restoration of mobility [24]. For glenohumeral osteoarthritis with an intact rotator cuff, reverse arthroplasty is appropriate and achieves highly favorable outcomes [14]. In humeral head avascular necrosis, shoulder replacement is indicated to improve pain, range of motion, and functionality with a low risk of complications [96]. For the arthritic knee, unicompartmental and bicompartmental arthroplasty with a finned metal tibial-plateau implant is indicated with proper selection [6]. Conversion of a fused knee to total knee arthroplasty is indicated for patients seeking improved fixation and satisfaction [60].

Surgical Approach / Technique: Total shoulder arthroplasty using a stemless humeral component accurately reproduces native anatomy in the majority of cases [66]. Additive manufacturing for metal applications offers improved biomechanical properties and fixation systems, enabling use in areas where current implants are not well suited [43]. For proximal interphalangeal joint arthroplasty, there is no evidence that one surgical approach is superior to another [25]. When a silastic radial-head prosthesis fractures, removal of loose fragments is recommended and a second replacement attempt should be avoided [50].

Implant Selection: In nearly 95% of knees for which total arthroplasty is indicated, a non-constrained cruciate-preserving prosthesis provides adequate pain relief, satisfactory axial alignment, and stability [102]. Specific indications for the variety of glenoid implants available for anatomic total shoulder arthroplasty are still being studied [40]. Biologic resurfacing of the glenoid may have a minimal and undefined role in young active patients compared to traditional hemiarthroplasty or total shoulder arthroplasty [94]. Prosthesis loosening was not detected with a cemented surface replacement prosthesis in the basal thumb joint [7]. At 3 years, a new stemless shoulder prosthesis shows radiologic evidence of maintained stability and good primary fixation [45].

Pain Management: Patients managed with a total joint regional anesthesia protocol emphasizing peripheral nerve blockade demonstrated better pain control, earlier walking ability, and earlier discharge compared to historical controls [93]. Patients with high preoperative pain scores are at risk for postoperative pain reduction that will not be clinically relevant after proximal interphalangeal joint arthroplasty for osteoarthritis [91].

Adjuncts: Collaborative guidelines between orthopaedics and rheumatology present useful protocols for perioperative medication management in rheumatic patient populations undergoing total hip or total knee arthroplasty [13].

Setting of Care: Novel processes to reduce the cost of admission for treatment of infected shoulder arthroplasty have broad implications for managing periprosthetic joint replacement and reducing healthcare costs [5]. To make arthroplasty affordable globally, device manufacturers must design devices usable and affordable in emerging markets by addressing regional anatomic diversity and economic needs, focusing on simpler, novel solutions that prioritize affordability without sacrificing clinical success [11].

Revision: Over 80% of revision replacements last 5 years and over 70% last 10 years [4]. Resection arthroplasty is effective in relieving pain for failed shoulder arthroplasty, but patients have poor postoperative function [74]. Patients define successful management of periprosthetic joint infection following total joint arthroplasty by emphasizing function, pain relief, mobility, and independence [97].

Other Considerations: Final recommendations based on literature and expert consensus provide a resource for guiding decision-making for stakeholders in the clinical introduction of artificial joint arthroplasty devices [1]. Experts propose using the GRADE system to develop conclusive guidance or consensus statements on controversial issues in joint arthroplasty [2]. Surgeons must examine existing literature on outcomes for different arthroplasty options to maximize clinical outcomes and revision-free implant survival [3]. Implant arthroplasty has been dramatically successful in terms of relief of pain and maintenance of variable degrees of improved function [8]. Utilization of joint preserving procedures for osteonecrosis of the humeral head is growing over time, notably in patients under 50 years of age, although shoulder arthroplasty remains predominant [10]. There is increasing interest in the use of a constrained or reverse total shoulder arthroplasty to treat cuff tear arthropathy, with promising early results [27]. A total of 13% of joints treated with proximal interphalangeal joint pyrocarbon implants required a secondary surgical procedure [28]. Management of glenohumeral osteoarthritis remains controversial and the scientific evidence on this topic can be significantly improved [100]. Surgical implant type, indication, patient comorbidities, and hospital factors contribute to differential surgical cost for total shoulder arthroplasty [18].

Complications

Infection (PJI): The incidence of periprosthetic joint infection (PJI) after primary total knee replacement is 0.4% to 2% [106]. Late deep wound infection secondary to hematogenous spread is an infrequent but devastating complication of total joint replacement [126]. Prior nonshoulder PJI increases rates of 90-day surgical site infection, sepsis, and hospital readmission, as well as 2-year all-cause revision after primary total shoulder arthroplasty [122]. Prior hip or knee prosthetic joint infection in another joint increases the risk of PJI after primary total knee arthroplasty three-fold [129]. The risk of PJI is 15-fold higher in patients on chronic antibiotic suppression [129]. Patients with multiple joint arthroplasties and a history of PJI have metachronous PJI rates ranging from 3% to 19% and synchronous PJI rates from 1.3% to 6% [110]. The overall rate of PJI eradication is significantly higher with single-stage management (95.6%) compared to two-stage protocols (85.7%) [135].

Aseptic loosening: Primary total elbow arthroplasty with the Nexel implant is associated with an unacceptably high rate of early implant loosening, periprosthetic fracture, and reoperation [112]. The rate of early aseptic failure for an uncemented thumb carpometacarpal joint ceramic prosthesis is unacceptably high [128]. Cement-within-cement technique in revision reverse total shoulder arthroplasty is associated with higher rates of complications and re-revision surgery over time due to aseptic glenoid component loosening and instability [109]. Clinical outcomes for surface replacement trapeziometacarpal joint prosthesis deteriorate clearly in cases of loosening, though they remain excellent in patients with stable implants [124].

Instability: Cement-within-cement technique in revision reverse total shoulder arthroplasty is associated with higher rates of complications and re-revision surgery over time due to aseptic glenoid component loosening and instability [109].

Periprosthetic fracture: Primary total elbow arthroplasty with the Nexel implant is associated with an unacceptably high rate of early implant loosening, periprosthetic fracture, and reoperation [112]. Hemi arthroplasty and total elbow arthroplasty for unreconstructable distal humeral fractures in patients over 65 years have similarly high complication rates [138].

Thromboembolism: The prevalence of venous thromboembolism (VTE) after total shoulder arthroplasty is low [123]. Patients 80 years and older undergoing reverse total shoulder arthroplasty have higher early mortality and medical complication rates, including DVT, renal failure, and pneumonia, than patients under 80 years of age [133].

Other Considerations: Revision shoulder replacements last 5 years in over 80% of cases and 10 years in over 70% of cases [4]. Primary arthroplasty yields good or excellent results in 92% of patients, while surgical revision yields good or excellent results in 81% of patients [21]. The probability of polycentric total knee arthroplasty remaining successful ten years postoperatively is 66% [22]. Complication, reoperation, and revision rates for primary reverse total shoulder arthroplasty in patients younger than 65 years are similar to those in older cohorts, without an increase in revisions due to aseptic loosening [111]. Primary reverse shoulder arthroplasty in patients aged 65 years or younger yields good short-term to medium-term outcomes with high implant survival, though smoking increases the risk for revision, reoperation, and complications [115]. The overall rate of subsequent procedures for Ream-and-Run shoulder arthroplasty is 19%, with a prosthetic revision rate of 12% at a mean of 10 years [117]. Twenty-eight percent of patients undergoing pyrolytic carbon proximal interphalangeal joint arthroplasty required a second procedure, and 8% required a revision arthroplasty [118]. Primary shoulder arthroplasty is associated with low 90-day reoperation and complication rates [127]. After 1 year, there is no increased risk of complications, revision, or inferior outcomes for reverse total shoulder arthroplasty in patients younger than 65 years compared to patients older than 65 years [134]. There are no significant differences in clinical outcomes or complication rates between standard components and fracture-specific components in reverse shoulder arthroplasty for proximal humerus fractures [139]. Clinical studies reveal a similar incidence of implant failure for shoulder arthroplasty compared to data from worldwide arthroplasty registries [137].

Recovery

Implant arthroplasty has been dramatically successful in terms of relief of pain and maintenance of variable degrees of improved function [8]. Survivorship data indicates that over 80% of revision shoulder replacements last 5 years [4], and over 70% last 10 years [4]. For knee arthroplasty, ninety-two per cent of patients who had primary knee arthroplasty had a good or excellent result [21], while eighty-one per cent of patients who had surgical revision of the knee had a good or excellent result [21]. The calculated probability of unicompartmental and bicompartmental knee arthroplasty remaining successful ten years postoperatively was 66 per cent [22].

Light activity (weeks): Specific timelines for desk work, driving, or light ADLs are not detailed in the current evidence base.

Full activity (months): Specific timelines for manual work, sport, or full ROM/strength return are not detailed in the current evidence base.

Complete recovery / outcome plateau (months): Recovery plateaus between 6 to 12 months after reverse shoulder arthroplasty [125].

Rehabilitation protocol: Evidence does not specify immobilisation duration, weight-bearing protocols, or sling removal timing. However, early reported results suggest that the average functional outcome of reverse shoulder arthroplasty for proximal humeral fractures may be better than hemiarthroplasty in certain patients and specific clinical scenarios, with results reached more quickly and with less dependence on rehabilitation [116].

Functional milestones: Reverse total shoulder arthroplasty restores function in the shoulder with significant improvements in function and moderate complications [86]. At mid-term follow-up, patients with a history of anterior shoulder instability undergoing total shoulder arthroplasty can expect continued improvement in function compared with preoperative values [120]. At early- to mid-term follow-up, total shoulder arthroplasty performed after a coracoid transfer demonstrated similar results to total shoulder arthroplasty performed for primary osteoarthritis [67]. Shoulder hemiarthroplasty provides sustained good-to-excellent pain relief and functional improvement at five to ten years postoperatively in carefully selected patients with osteoarthritis [140, 141]. The study reports functional outcomes and high prosthesis survivorship at midterm follow-up for B2 and B3 glenoid osteoarthritis treated with corrective and concentric reaming of the glenoid combined with pyrocarbon hemiarthroplasty [113]. Revision of an unstable hemiarthroplasty or anatomical total shoulder replacement using a reverse design prosthesis gives good relief of pain and increases active elevation, although the overall results are inferior to the outcome following the use of reverse arthroplasty in patients with cuff-tear arthropathy [130].

Other Considerations: The literature reports that rates of return for total shoulder arthroplasty are slightly higher than those reported for reverse total shoulder arthroplasty and hemiarthroplasty [61]. Higher return to work rates were seen in patients who were not on sick leave preoperatively after reverse total shoulder arthroplasty [73]. Patients are interested in the timeline of recovery, ability to perform specific activities after surgery, and short-term and long-term restrictions following reverse total shoulder arthroplasty [119]. Patient expectations for functional improvements after revision of failed reverse total shoulder arthroplasty with reverse should be tempered, and a high reoperation rate should be expected [72]. Patients traveling after total shoulder replacement are often delayed and subjected to more rigorous screening when traveling, especially in the post-9/11 environment [68].

  • [L5] Radiographic osteolysis after total shoulder arthroplasty may lead to clinically important complications such as aseptic loosening. (10.5397/cise.2021.00738)
  • [L4] Although a low rate of humeral component loosening was observed, higher rates of complications and re-revision surgery were observed over time secondary to aseptic glenoid component loosening and instability. (10.1016/j.xrrt.2024.08.006)
  • [L4] Patients with multiple joint arthroplasties and a history of PJI are at higher risk for developing a second PJI, with metachronous rates ranging from 3% to 19% and synchronous rates from 1.3% to 6%. (10.5435/jaaos-d-23-00120)

By exercising the Licensed Rights (defined below), You accept and agree to be bound by the terms and conditions of this Creative Commons Attribution-NonCommercial 4.0 International Public License ("Public License"). To the extent this Public License may be interpreted as a contract, You are granted the Licensed Rights in consideration of Your acceptance of these terms and conditions, and the Licensor grants You such rights in consideration of benefits the Licensor receives from making the Licensed Material available under these terms and conditions.

Section 1 -- Definitions.

a. Adapted Material means material subject to Copyright and Similar Rights that is derived from or based upon the Licensed Material and in which the Licensed Material is translated, altered, arranged, transformed, or otherwise modified in a manner requiring permission under the Copyright and Similar Rights held by the Licensor. For purposes of this Public License, where the Licensed Material is a musical work, performance, or sound recording, Adapted Material is always produced where the Licensed Material is synched in timed relation with a moving image.

b. Adapter's License means the license You apply to Your Copyright and Similar Rights in Your contributions to Adapted Material in accordance with the terms and conditions of this Public License.

c. Copyright and Similar Rights means copyright and/or similar rights closely related to copyright including, without limitation, performance, broadcast, sound recording, and Sui Generis Database Rights, without regard to how the rights are labeled or categorized. For purposes of this Public License, the rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.

d. Effective Technological Measures means those measures that, in the absence of proper authority, may not be circumvented under laws fulfilling obligations under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996, and/or similar international agreements.

e. Exceptions and Limitations means fair use, fair dealing, and/or any other exception or limitation to Copyright and Similar Rights that applies to Your use of the Licensed Material.

f. Licensed Material means the artistic or literary work, database, or other material to which the Licensor applied this Public License.

g. Licensed Rights means the rights granted to You subject to the terms and conditions of this Public License, which are limited to all Copyright and Similar Rights that apply to Your use of the Licensed Material and that the Licensor has authority to license.

h. Licensor means the individual(s) or entity(ies) granting rights under this Public License.

i. NonCommercial means not primarily intended for or directed towards commercial advantage or monetary compensation. For purposes of this Public License, the exchange of the Licensed Material for other material subject to Copyright and Similar Rights by digital file-sharing or similar means is NonCommercial provided there is no payment of monetary compensation in connection with the exchange.

j. Share means to provide material to the public by any means or process that requires permission under the Licensed Rights, such as reproduction, public display, public performance, distribution, dissemination, communication, or importation, and to make material available to the public including in ways that members of the public may access the material from a place and at a time individually chosen by them.

k. Sui Generis Database Rights means rights other than copyright resulting from Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, as amended and/or succeeded, as well as other essentially equivalent rights anywhere in the world.

l. You means the individual or entity exercising the Licensed Rights under this Public License. Your has a corresponding meaning.

Section 2 -- Scope.

a. License grant.

1. Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to:

a. reproduce and Share the Licensed Material, in whole or in part, for NonCommercial purposes only; and

b. produce, reproduce, and Share Adapted Material for NonCommercial purposes only.

2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions and Limitations apply to Your use, this Public License does not apply, and You do not need to comply with its terms and conditions.

3. Term. The term of this Public License is specified in Section 6(a).

4. Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a) (4) never produces Adapted Material.

5. Downstream recipients.

a. Offer from the Licensor -- Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License.

b. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material.

6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).

b. Other rights.

1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.

2. Patent and trademark rights are not licensed under this Public License.

3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties, including when the Licensed Material is used other than for NonCommercial purposes.

Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the following conditions.

a. Attribution.

1. If You Share the Licensed Material (including in modified form), You must:

a. retain the following if it is supplied by the Licensor with the Licensed Material:

iii. a notice that refers to this Public License;

iv. a notice that refers to the disclaimer of warranties;

v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable;

3. If requested by the Licensor, You must remove any of the information required by Section 3(a)(1)(A) to the extent reasonably practicable.

4. If You Share Adapted Material You produce, the Adapter's License You apply must not prevent recipients of the Adapted Material from complying with this Public License.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:

a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database for NonCommercial purposes only;

b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and

c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

Section 6 -- Term and Termination.

a. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.

b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates:

1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or

2. upon express reinstatement by the Licensor.

For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.

c. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.

d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

Section 7 -- Other Terms and Conditions.

a. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.

Section 8 -- Interpretation.

a. For the avoidance of doubt, this Public License does not, and shall not be interpreted to, reduce, limit, restrict, or impose conditions on any use of the Licensed Material that could lawfully be made without permission under this Public License.

b. To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions.

c. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor.

d. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.
