Overview¶
Total shoulder arthroplasty encompasses anatomic and reverse configurations, with the latter experiencing a rapid rise in use driven by expanded indications, improved surgical technique, and enhanced implant design [14]. Reverse total shoulder arthroplasty use has notably increased among patients younger than 60 years of age [48]. While reverse total shoulder arthroplasty yields outcomes comparable to anatomic total shoulder arthroplasty with very low reoperation rates [14], it does not appear to offer functional benefits over anatomic total shoulder arthroplasty in patients with primary osteoarthritis, an intact rotator cuff, and no glenoid deformity [7]. 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]. 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]. 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].
Long-term management and prognosis are influenced by specific patient factors. 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]. 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]. Regarding contralateral outcomes, early results 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¶
Kinematics and Biomechanics¶
Shoulder arthroplasty to address sequelae of anterior instability arthropathy and stabilization procedures is challenging due to distorted anatomy and severe glenohumeral joint pathology [2]. 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 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 the increased scapulothoracic contribution [46].
Isolated humeral distalization in rTSA caused 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 was observed with higher glenohumeral abduction angles for both elliptical and spherical head designs [40]. Joint stability and abduction capability were compromised by more extensive rotator cuff tears, and subscapularis repair might be essential to enhancing biomechanical effectiveness in lateralized rTSA [52]. Clavicle hook plate fixation changes scapular kinematics and scapulohumeral rhythm [49].
Preoperative Planning and Imaging¶
Preoperative planning using supine CT may inaccurately pose bones, with consequent effects on the surgical plan, resultant shoulder biomechanics, and clinical outcomes [35]. Predicted impingement-free motion amplitudes in rTSA differ between supine computed tomography and standing biplanar x-ray imaging [45]. Adjusting patient-specific scapula posture significantly impacts predicted impingement-free motion amplitudes and range of motion in rTSA [45]. All movement planes showed significant differences in simulated range of motion when comparing protocols with and without adjustment for posture [41]. Shoulder surgeons must understand key aspects of 3D preoperative planning software, including segmentation techniques, landmark definition, and potential limitations, to mitigate risks of errors in the surgical procedure [54].
Classification¶
Indication-Based Stratification: The outcome of revision shoulder arthroplasty is predictable based on the specific indication for the procedure [3]. A model utilizing specific patient characteristics demonstrates good predictive properties for identifying patients likely to achieve better outcomes from shoulder arthroplasty [8].
Anatomic and Pathologic Subtypes: Shoulder arthroplasty to address sequelae of anterior instability arthropathy and prior stabilization procedures is challenging due to distorted anatomy and severe glenohumeral joint pathology [2]. Reverse total shoulder arthroplasty does not offer functional benefits over anatomic total shoulder arthroplasty for primary osteoarthritis with an intact rotator cuff and no glenoid deformity [7].
Risk and Resource Stratification: Patient-level variables (age, comorbidity burden, ASA score, and trauma indication) and system-level variables (weekend surgery and surgeon volume) are independently associated with prolonged length of stay following shoulder arthroplasty [51]. Surgical implant type, indication, patient comorbidities, and hospital factors contribute to differential surgical cost for total shoulder arthroplasty [6]. Preoperative 3-dimensional computed tomography bone density measures provide objective bone quality classifications for stemless anatomic total shoulder arthroplasty [23].
Other Considerations: Long-term follow-up and surveillance recommendations for elective primary shoulder arthroplasty were established using a real-time Delphi technique [1]. Shoulder replacement is a viable treatment option regardless of patient tobacco usage at short-term follow-up, though this may vary depending on the replacement type used [5]. Substantial variation exists in implant selection and surgical technique for reverse shoulder replacement in the United Kingdom [15]. The decision to revise a total shoulder arthroplasty requires rigorous assessment regarding 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 resulted in better shoulder function than conventional GS-type management [20]. Data on health care resource utilization in the 2 years prior to total shoulder arthroplasty provide a baseline for understanding trends regarding nonarthroplasty treatment of shoulder pathology before replacement [28]. Studies with higher levels of evidence may overtake the most-cited articles in reverse total shoulder arthroplasty as the procedure continues to grow [29].
Clinical Presentation¶
Shoulder arthroplasty to address the sequelae of anterior instability arthropathy and stabilization procedures is challenging due to distorted anatomy and severe glenohumeral joint pathology [2]. 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]. Most patients undergoing shoulder stabilization procedures regained fundamental strength and range of motion [12].
Current comorbidity indices inadequately identify patients who experience early adverse outcomes following total shoulder arthroplasty [33]. However, a model based on specific patient characteristics had good predictive properties for identifying patients likely to have a better outcome from shoulder arthroplasty [8]. Shoulder replacement is 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]. There are minimal gender differences in shoulder arthroplasty outcomes, with both genders achieving similar long-term results in pain relief and function [22].
Two PROMIS measures commonly administered in orthopedic surgery settings, physical function and pain interference, can be used to estimate high-impact chronic pain for patients receiving total shoulder arthroplasty [21]. Nonagenarians are at an increased risk of medical complications, longer hospital stays, periprosthetic fractures, and death following total shoulder arthroplasty [13].
Glenoid Morphology and Implant Selection¶
Good functional results can be achieved in cases with a B1 and a B2 glenoid after anatomic shoulder arthroplasty using a metal back glenoid component [24]. Although a high prevalence of radiographic signs associated with rotator cuff failure and glenoid wear were reported after anatomic total shoulder arthroplasty with an all-polyethylene cemented glenoid component at minimum 10-year follow-up, this did not translate to a high complication rate or inferior outcome [18].
Functional Outcomes and Return to Activity¶
Rates of return to play after total shoulder arthroplasty are slightly higher than those reported for reverse total shoulder arthroplasty and hemiarthroplasty [9]. Activities entailing greater shoulder demands may hinder a patient's ability to return to outdoorsman sports after primary total shoulder arthroplasty [19].
Revision Assessment¶
Revision of 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 3-dimensional computed tomography bone density measures provide objective bone quality classifications for stemless anatomic total shoulder arthroplasty [23]. Preoperative shoulder CT may be associated with a small but quantifiable projected cancer risk, most pronounced in younger women [62]. Navigation increases the accuracy of glenoid component implantation in reverse total shoulder arthroplasty in shoulders with severe glenoid wear [69].
Tomosynthesis: Tomosynthesis may be a new and effective modality for evaluating glenoid loosening [68].
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].
Other Considerations: Consensus recommendations exist for long-term follow-up and surveillance of elective primary shoulder arthroplasty [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 to address sequelae of anterior instability arthropathy and prior stabilization procedures is challenging due to distorted anatomy and severe glenohumeral joint pathology [2]. 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]. A predictive model based on specific patient characteristics can identify patients likely to have a better outcome from shoulder arthroplasty [8]. Nonagenarians are at an increased risk of medical complications, longer hospital stays, periprosthetic fractures, and death following total shoulder arthroplasty [13].
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]. 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].
Implant Selection: Reverse total shoulder arthroplasty does not appear to 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]. Shoulder metallosis is an infrequent but significant potential complication in patients who have undergone shoulder arthroplasty with retained metallic suture anchors [59].
Pain Management: Intraoperative tranexamic acid does not improve range of motion or pain after total shoulder arthroplasty [64].
Adjuncts: 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]. Shoulder replacement is 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].
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: The outcome of revision shoulder arthroplasty can be predicted based on the indication for the procedure [3]. Comparable infection eradication rates are achieved after two-stage revision, resection arthroplasty, or permanent spacer implant for the treatment of septic shoulder prosthesis [30]. 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].
Other Considerations: Long-term follow-up and surveillance guidelines for elective primary shoulder arthroplasty have been established using a real-time Delphi technique [1]. Most patients undergoing shoulder stabilization procedures regain fundamental strength and range of motion [12]. There are minimal gender differences in shoulder arthroplasty outcomes, with both genders achieving similar long-term results in pain relief and function [22]. 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]. 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]. 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]. Surgical implant type, indication, patient comorbidities, and hospital factors contribute to differential surgical cost for total shoulder arthroplasty [6].
Complications¶
Infection (PJI): Non-cefazolin antibiotic prophylaxis is associated with increased rates of acute infectious, medical, and surgical complications following primary total shoulder arthroplasty [80]. Perioperative testosterone use is associated with a significantly higher risk of periprosthetic joint infection (PJI) following primary total shoulder arthroplasty, but no differences are found in rates of other major complications including revision rates, dislocation, aseptic loosening, periprosthetic fracture, and stiffness [83]. Prescription testosterone is associated with an increased risk of infection-related and all-cause reoperations after primary total shoulder arthroplasty in male patients [82]. Comparable infection eradication rates exist after two-stage revision, resection arthroplasty, or permanent spacer implant for the treatment of septic shoulder prosthesis [30].
Instability: Instability is a challenging complication with high failure rates after revision procedures, prompting a movement toward reverse 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 secondary to aseptic glenoid component loosening and instability [55].
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 to address sequelae of anterior instability arthropathy and stabilization procedures is challenging due to distorted anatomy and severe glenohumeral joint pathology [2]. The Latarjet procedure is associated with the highest odds of future total shoulder arthroplasty [78]. 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 conclusions may vary depending on the replacement type [5]. Return-to-play rates are slightly higher for total shoulder arthroplasty compared to reverse total shoulder arthroplasty and hemiarthroplasty [9]. Success after first anatomic total shoulder arthroplasty does not reliably predict contralateral success until 1 year, whereas early outcomes after first reverse total shoulder arthroplasty do [10]. 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]. 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]. Pseudoaneurysm is an uncommon but possible complication after shoulder arthroplasty [81].
Recovery¶
Long-term follow-up and surveillance of elective primary shoulder arthroplasty are recommended via consensus guidelines [1].
Light activity (weeks): Acute recovery after total shoulder arthroplasty can be assessed via maximum elevation [26]. 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].
Full activity (months): A high return to sport can be expected after total shoulder arthroplasty [43]. Return to sports after reverse shoulder arthroplasty is 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]. Activities entailing greater shoulder demands may hinder a patient's ability to return after arthroplasty [19].
Complete recovery / outcome plateau (months): The plateau of maximum recovery following rotator cuff repair occurred at 1 year with high satisfaction rates at all time points [60]. Success after first anatomic total shoulder arthroplasty does not reliably predict contralateral success until 1 year, whereas early outcomes after first reverse total shoulder arthroplasty better prognosticate contralateral success [10].
Rehabilitation protocol: A progression of exercises for patients after reverse shoulder arthroplasty can be based on increased muscle activity [47].
Functional milestones: Chronic recovery after total shoulder arthroplasty can be assessed via time spent above 90 degrees of elevation [26]. Among shoulder arthroplasty 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].
Other Considerations: 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]. 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].
