Total shoulder arthroplasty¶
Surgeon-side topic for total shoulder arthroplasty. Backed by 412 articles from the corpus, retrieved via combined MeSH + title-text matching.
Overview¶
Total shoulder arthroplasty encompasses anatomic and reverse designs, with the latter experiencing a rapid rise in use driven by expanded indications, improved surgical technique, implant design, and surgeon experience [14]. While reverse total shoulder arthroplasty is increasingly utilized in patients younger than 60 years of age, this demographic experiences significantly higher rates of 90-day surgical complications compared to older patients [48]. For patients with primary osteoarthritis, an intact rotator cuff, and no glenoid deformity, reverse total shoulder arthroplasty does not appear to offer functional benefits over anatomic total shoulder arthroplasty [7]. However, reverse total shoulder arthroplasty yields outcomes comparable to anatomic procedures with very low reoperation rates [14]. Return rates for total shoulder arthroplasty are slightly higher than those reported for reverse total shoulder arthroplasty and hemiarthroplasty [9].
Surgical implant type, indication, patient comorbidities, and hospital factors contribute to differential surgical cost for total shoulder arthroplasty [6]. Shoulder replacement remains a viable treatment option regardless of patient tobacco usage at short-term follow-up, although conclusions may vary depending on the replacement type used [5]. Outpatient total shoulder arthroplasty is a safe and effective option for appropriately selected patients, offering reduced costs, improved access, and high patient satisfaction compared to inpatient procedures [17]. Patients with a history of anterior shoulder instability undergoing total shoulder arthroplasty can expect continued improvement in function compared with preoperative values at mid-term follow-up [4].
Long-term management and prognostication require specific surveillance and outcome monitoring. Consensus recommendations for long-term follow-up and surveillance of elective primary shoulder arthroplasty were developed using a real-time Delphi technique [1]. The outcome of revision shoulder arthroplasty can be predicted based on the indication for the procedure [3]. Early outcomes after first reverse total shoulder arthroplasty better prognosticate contralateral success compared with early outcomes after anatomic total shoulder arthroplasty [10]. Success after first anatomic total shoulder arthroplasty does not reliably predict contralateral success until 1 year [10].
Anatomy & Pathophysiology¶
Osseous and Glenohumeral Mechanics¶
Shoulder arthroplasty to address sequelae of anterior instability arthropathy and stabilization procedures is challenging due to distorted anatomy and severe glenohumeral joint pathology [2]. Preoperative planning using supine CT may inaccurately pose bones, with consequent effects on the surgical plan, resultant shoulder biomechanics, and clinical outcomes [35]. All movement planes show significant differences in simulated ROM when comparing preoperative planning protocols with and without adjustment for posture [41]. Adjusting patient-specific scapula posture significantly impacts predicted impingement-free motion amplitudes and ROM in rTSA [45].
Kinematics and Scapulothoracic Contribution¶
Reverse total shoulder arthroplasty (rTSA) restores forward elevation primarily via compensatory scapulothoracic motion and deltoid-driven neuromuscular strategies rather than normalization of glenohumeral mechanics [32]. The scapulothoracic (ST) contribution to overall shoulder movement is significantly increased in patients with an rTSA compared with a healthy shoulder [37]. There is an increased contribution of scapulothoracic rotation relative to glenohumeral motion throughout arm elevation following TSA compared to asymptomatic shoulders [42]. Postoperative changes in scapular kinematics following rTSA positively impact shoulder function and patient-reported outcome measures [36]. Significant changes from preoperative to postoperative conditions were not demonstrated for other kinematic parameters beyond those already noted in rTSA [46].
Biomechanical Load and Range of Motion¶
Isolated humeral distalization in rTSA causes dramatic increases in the muscle forces required to perform scapular-plane abduction, with joint reaction forces increasing correspondingly [39]. A general decrease in the degree of rotational range of motion (ROM) is observed with higher glenohumeral abduction angles for both elliptical and spherical head designs [40]. The study quantifies biomechanical shifts regarding varus-valgus alignment of humeral short stems in rTSA but does not explicitly state a final clinical conclusion regarding the functional impact of these misalignments [44].
Soft Tissue and Stabilization¶
Clavicle hook plate fixation changes scapular kinematics and scapulohumeral rhythm [49]. Joint stability and abduction capability are compromised by more extensive rotator cuff tears, and subscapularis repair might be essential to enhancing biomechanical effectiveness in lateralized rTSA [52].
Classification¶
Consensus Guidelines: Long-term follow-up and surveillance of elective primary shoulder arthroplasty are guided by consensus recommendations derived from a real-time Delphi technique [1].
Indication-Based Complexity: Shoulder arthroplasty for the sequelae of anterior instability arthropathy and prior stabilization procedures is classified as challenging due to distorted anatomy and severe glenohumeral joint pathology [2]. The outcome of revision shoulder arthroplasty is predicted by the specific indication for the procedure [3].
Risk Stratification: A predictive model based on specific patient characteristics has good properties for identifying patients likely to have a better outcome from shoulder arthroplasty [8].
Other Considerations: Implant Selection: Reverse total shoulder arthroplasty does not offer functional benefits over anatomic total shoulder arthroplasty for primary osteoarthritis with an intact rotator cuff in patients with no glenoid deformity [7]. Substantial variation exists in implant selection and surgical technique for reverse shoulder replacement, despite it being the predominant form of shoulder arthroplasty in the United Kingdom [15]. Shoulder replacement is a viable treatment option regardless of patient tobacco usage at short-term follow-up, although viability may vary depending on the replacement type used [5].
Revision Criteria: The decision to revise a total shoulder arthroplasty requires rigorous assessment regarding five key factors: infection, instability, wear, loosening, and rotator cuff status [16]. Retention of osseointegrated prosthetic implants during surgical management of chronic infections following reverse total shoulder arthroplasty results in better shoulder function than conventional GS-type management [20].
Preoperative Assessment: Preoperative 3-dimensional computed tomography bone density measures provide objective bone quality classifications for stemless anatomic total shoulder arthroplasty [23]. Health care resource utilization data from the 2 years prior to total shoulder arthroplasty provides a baseline for understanding trends in nonarthroplasty treatment of shoulder pathology before replacement [28].
Economic and System Factors: Differential surgical cost for total shoulder arthroplasty is contributed to by surgical implant type, indication, patient comorbidities, and hospital factors [6]. Prolonged length of stay following shoulder arthroplasty is independently associated with patient-level variables (age, comorbidity burden, ASA score, and trauma indication) and system-level variables (weekend surgery and surgeon volume) [51].
Literature Trends: Reverse total shoulder arthroplasty is a growing field where studies with higher levels of evidence may overtake older, highly cited articles in the future [29].
Clinical Presentation¶
Preoperative Assessment and Patient Selection¶
The decision to proceed with total shoulder arthroplasty requires rigorous preoperative evaluation, particularly in complex cases. Revision surgery to address sequelae of anterior instability arthropathy or prior stabilization procedures is challenging due to distorted anatomy and severe glenohumeral joint pathology [2]. The outcome of such revision procedures can be predicted based on the specific indication for the procedure [3]. For patients with a history of anterior shoulder instability undergoing total shoulder arthroplasty, continued improvement in function compared with preoperative values is expected at mid-term follow-up [4].
Patient-specific factors significantly influence surgical planning and outcomes. A model based on specific patient characteristics demonstrates good predictive properties for identifying patients likely to have a better outcome from shoulder arthroplasty [8]. Current comorbidity indices, however, inadequately identify patients who experience early adverse outcomes following total shoulder arthroplasty [33]. There are minimal gender differences in shoulder arthroplasty outcomes, with both genders achieving similar long-term results in pain relief and function [22]. Shoulder replacement remains a viable treatment option regardless of patient tobacco usage at short-term follow-up, though conclusions may vary depending on the replacement type used [5].
Risk Stratification and Functional Expectations¶
Risk assessment must account for age and activity demands. Nonagenarians are at an increased risk of medical complications, longer hospital stays, periprosthetic fractures, and death following total shoulder arthroplasty [13]. Return-to-play rates for total shoulder arthroplasty are slightly higher than those reported for reverse total shoulder arthroplasty and hemiarthroplasty [9]. However, activities entailing greater shoulder demands may hinder a patient's ability to return to outdoorsman sports after primary total shoulder arthroplasty [19]. Two PROMIS measures, physical function and pain interference, can be used to estimate high-impact chronic pain for patients receiving total shoulder arthroplasty [21].
Glenoid Morphology and Implant Considerations¶
Glenoid exposure is a difficult but key step in total shoulder arthroplasty that conditions correct component positioning [11]. Good functional results can be achieved in cases with B1 and B2 glenoid morphology after anatomic shoulder arthroplasty using a metal back glenoid component [24]. Anatomic total shoulder arthroplasty using an all-polyethylene cemented glenoid component shows a high prevalence of radiographic signs associated with rotator cuff failure and glenoid wear at minimum 10-year follow-up, but this does not translate to a high complication rate or inferior outcome [18].
Postoperative Surveillance and Revision Indications¶
Long-term follow-up and surveillance guidelines for elective primary shoulder arthroplasty are established via consensus using a real-time Delphi technique [1]. Most patients undergoing shoulder stabilization procedures regain fundamental strength and range of motion [12]. The decision to revise a total shoulder arthroplasty requires a rigorous assessment regarding infection, instability, wear, loosening, and rotator cuff status [16]. Surgical implant type, indication, patient comorbidities, and hospital factors contribute to differential surgical cost for total shoulder arthroplasty [6].
Investigations¶
Plain radiography: Radiographic measurements are generally valid for evaluating postoperative parameters in reverse total shoulder arthroplasty [58]. However, routine radiographs are overused and typically do not lead to any changes in asymptomatic patients in the first 2 years after total shoulder arthroplasty [72].
CT: Preoperative shoulder CT may be associated with a small but quantifiable projected cancer risk, which is most pronounced in younger women [62]. Preoperative 3-dimensional computed tomography bone density measures provide objective classifications of bone quality for stemless anatomic total shoulder arthroplasty [23]. Navigation increases the accuracy of glenoid component implantation in reverse total shoulder arthroplasty in shoulders with severe glenoid wear [69].
Ultrasound: Ultrasound imaging is an efficient, easy to use, and inexpensive tool for the diagnosis and management of the painful shoulder, with advantages over other modalities for evaluating the postoperative shoulder [67].
Tomosynthesis: Tomosynthesis may be a new and effective modality for evaluating glenoid loosening [68].
Other Considerations: Long-term follow-up and surveillance of elective primary shoulder arthroplasty should be guided by consensus recommendations derived from a real-time Delphi technique [1].
Treatment¶
Non-Operative¶
Data on health care resource utilization in the 2 years prior to total shoulder arthroplasty provide a baseline for understanding current trends regarding nonarthroplasty treatment of shoulder pathology [28].
Operative¶
Indications: Shoulder arthroplasty addresses sequelae of anterior instability arthropathy and prior stabilization procedures, though this is challenging due to distorted anatomy and severe glenohumeral joint pathology [2]. The outcome of revision shoulder arthroplasty can be predicted based on the indication for the procedure [3]. A predictive model based on specific patient characteristics can identify patients likely to have a better outcome from shoulder arthroplasty [8]. Patients with a history of anterior shoulder instability undergoing total shoulder arthroplasty can expect continued improvement in function compared with preoperative values at mid-term follow-up [4]. Shoulder replacement is a viable treatment option regardless of patient tobacco usage at short-term follow-up, although outcomes may vary depending on the replacement type used [5]. Nonagenarians are at an increased risk of medical complications, longer hospital stays, periprosthetic fractures, and death following total shoulder arthroplasty [13]. There are minimal gender differences in shoulder arthroplasty outcomes, with both genders achieving similar long-term results in pain relief and function [22].
Surgical Approach / Technique: Glenoid exposure is a difficult but key step in total shoulder arthroplasty that conditions correct component positioning [11]. Strict operative technique during reverse shoulder arthroplasty for recent proximal humerus fractures is crucial to obtain reliable outcomes, as inadequate tuberosity repair or inappropriate humeral stem position are associated with poorer outcomes [34].
Implant Selection: Reverse total shoulder arthroplasty does not offer functional benefits over anatomic total shoulder arthroplasty in patients with primary osteoarthritis, an intact rotator cuff, and no glenoid deformity [7]. The rapid rise in reverse total shoulder arthroplasty (RTSA) use is driven by expanded indications, improvements in surgical technique, implant design, and surgeon experience, resulting in outcomes comparable to anatomic total shoulder arthroplasty with very low reoperation rates [14]. Substantial variation exists in implant selection and surgical technique for reverse shoulder replacement despite it being the predominant form of shoulder arthroplasty in the United Kingdom [15]. Radiographic loosening over time remains a concern for all-polyethylene fluted central peg glenoid components implanted using an off-label, uncemented technique, potentially jeopardizing long-lasting fixation [57]. Functional improvement was obtained after reimplantation of a reverse total shoulder prosthesis for staged revision with antibiotic spacers, but was not seen after hemiarthroplasty and cement spacer [56].
Alignment / Balancing Strategy: Acute recovery after total shoulder arthroplasty can be assessed via maximum elevation, while chronic recovery can be assessed via time spent above 90 degrees of elevation [26].
Pain Management: Intraoperative tranexamic acid (TXA) does not improve range of motion or pain after total shoulder arthroplasty [64].
Adjuncts: Robotic-assisted arthroplasty is available for shoulder arthroplasty with some limitations, and surgeons should become familiar with its nature, potential benefits, disadvantages, and surgical techniques [31]. Shoulder metallosis is an infrequent but significant potential complication in patients who have undergone shoulder arthroplasty with retained metallic suture anchors [59].
Setting of Care: Outpatient total shoulder arthroplasty is a safe and effective option for appropriately selected patients, offering reduced costs, improved access, and high patient satisfaction compared to inpatient procedures [17].
Revision: Two-stage revision, resection arthroplasty, and permanent spacer implantation show comparable infection eradication rates for the treatment of septic shoulder prosthesis [30].
Other Considerations: Long-term follow-up and surveillance guidelines for elective primary shoulder arthroplasty have been established using a real-time Delphi technique [1]. Surgical implant type, indication, patient comorbidities, and hospital factors contribute to differential surgical cost for total shoulder arthroplasty [6]. Two Patient-Reported Outcomes Measurement Information System (PROMIS) measures, physical function and pain interference, can be used to estimate high-impact chronic pain for patients receiving total shoulder arthroplasty [21]. Most patients undergoing shoulder stabilization procedures regain fundamental strength and range of motion, though objective measures for assessing readiness to return to sport are not standardized [12]. Rehabilitation guidelines for reverse total shoulder replacement aim to achieve optimal pain relief and maximize functional outcomes while mitigating surgical risks [27]. Newer rehabilitation regimes permit immediate shoulder mobilization following reverse shoulder arthroplasty but may not be applied to every patient [61].
Complications¶
Infection (PJI): Perioperative testosterone use is associated with a significantly higher risk of periprosthetic joint infection (PJI) following primary total shoulder arthroplasty, without differences in other major complications including revision rates, dislocation, aseptic loosening, periprosthetic fracture, and stiffness [83]. Prescription testosterone use is associated with a higher risk of infection-related and all-cause reoperations after primary total shoulder arthroplasty in male patients [82]. Non-cefazolin antibiotic prophylaxis is associated with increased rates of acute infectious, medical, and surgical complications following primary total shoulder arthroplasty [80]. For septic shoulder prosthesis, two-stage revision, resection arthroplasty, and permanent spacer implant show comparable infection eradication rates [30].
Instability: Instability is a challenging complication with high failure rates after revision procedures for anatomic total shoulder arthroplasty [77]. The cement-within-cement technique in revision reverse total shoulder arthroplasty is associated with a low rate of humeral component loosening but higher rates of complications and re-revision surgery over time due to aseptic glenoid component loosening and instability [55]. The Latarjet procedure is associated with the highest odds of future total shoulder arthroplasty [78].
Periprosthetic fracture: Nonagenarians are at increased risk of medical complications, longer hospital stays, periprosthetic fractures, and death following total shoulder arthroplasty [13]. Patients from areas of high social deprivation have increased rates of humeral fracture and dislocation following primary total shoulder arthroplasty [79].
Other Considerations: Shoulder arthroplasty for instability arthropathy and sequelae of stabilization procedures is challenging due to distorted anatomy and severe glenohumeral joint pathology [2]. Revision shoulder arthroplasty outcomes can be predicted based on the indication for the procedure [3]. Shoulder replacement is a viable treatment option regardless of patient tobacco usage at short-term follow-up, though outcomes may vary by replacement type [5]. Revision shoulder arthroplasty has high direct costs driven by implant-related expenses and a high cost per improvement in patient-reported outcomes compared to primary arthroplasty [25]. The cement-within-cement technique in revision reverse total shoulder arthroplasty is associated with a low rate of humeral component loosening but higher rates of complications and re-revision surgery over time due to aseptic glenoid component loosening and instability [55]. Elevated preoperative international normalized ratio (INR) is associated with an increased risk of postoperative complications following total shoulder arthroplasty [71]. Revision rates and patient-reported outcomes are similar between cemented and uncemented humeral stems in reverse total shoulder arthroplasty for acute proximal humerus fracture [73]. Brachial artery pseudoaneurysm is an uncommon but possible complication after shoulder arthroplasty [81].
Recovery¶
Light activity (weeks): Acute recovery metrics are defined by maximum elevation [26]. Patients typically resume desk work, driving, and light activities of daily living within the early postoperative period, though specific week ranges are not detailed in the current evidence base.
Full activity (months): Return to sport is highly frequent and can be expected after total shoulder arthroplasty [43]. Return to sports after reverse shoulder arthroplasty is also possible and highly frequent [65]. Patients can be counseled that they can expect to successfully return to sporting and recreational activities following surgical reconstruction of their shoulder [70]. However, activities entailing greater shoulder demands may hinder a patient's ability to return to those specific activities after arthroplasty [19]. Among patients who perceive their shoulder as normal, anatomic total shoulder arthroplasty (aTSA) patients outperform reverse total shoulder arthroplasty (rTSA) patients with better motion and greater ability to return to work, return to sport, and perform higher demand activities without difficulty [50].
Complete recovery / outcome plateau (months): Chronic recovery is assessed via time spent above 90 degrees of elevation [26]. The plateau of maximum recovery following rotator cuff repair occurred at 1 year with high satisfaction rates at all time points [60]. Patients with a history of anterior shoulder instability undergoing total shoulder arthroplasty can expect continued improvement in function compared with preoperative values at mid-term follow-up [4]. Success after the first anatomic total shoulder arthroplasty does not reliably predict contralateral success until 1 year postoperatively [10].
Rehabilitation protocol: Rehabilitation guidelines for reverse total shoulder replacement aim to achieve optimal pain relief and maximize functional outcomes while mitigating surgical risks [27]. Early, active rehabilitation after reverse total shoulder arthroplasty is safe and effective, and may have early clinical benefits over a conservative, delayed mobilisation programme [38]. A progression of exercises for patients after reverse shoulder arthroplasty can be based on increased muscle activity [47].
Functional milestones: Long-term follow-up and surveillance guidelines for elective primary shoulder arthroplasty are anticipated to contribute to future clinical guidelines [1]. Return rates for total shoulder arthroplasty are slightly higher than those reported for reverse total shoulder arthroplasty and hemiarthroplasty [9]. Direct costs of revision shoulder arthroplasty are primarily driven by implant-related costs, and the cost per improvement in patient-reported outcomes is high compared to primary arthroplasty [25].
