Background US Food and Drug Administration Investigation Device Exemption studies and academic journals emphasize the importance of two-year follow-up data in reporting outcomes of total shoulder arthroplasty, but there is limited data evaluating appropriate follow-up length. We aim to evaluate change in postoperative outcomes and complications between one and two years following anatomic and reverse total shoulder arthroplasties. Methods We retrospectively identified 250 patients who underwent anatomic and reverse total shoulder arthroplasties between 2013 and 2016 from a single surgeon arthroplasty registry. Patients without both one- and two-year follow-up data were excluded. We compared American Shoulder and Elbow Surgeons (ASES) score, Visual Analog Scale for pain, and goniometer-measured range of motion. Results Patient-reported outcome measurements ( p > 0.05) did not change between one and two years postoperatively following both reverse ( n = 146) and anatomic ( n = 104) total shoulder arthroplasties. Range of motion increased slightly ( p < 0.05), but this change was not clinically relevant. There were no additional complications. Discussion Minimum two-year clinical follow-up may not be necessary for future shoulder arthroplasty Investigation Device Exemption and other peer-reviewed investigations. Patient-reported outcomes (ASES and pain score) and range of motion plateau at one year postoperatively without additional complications. One-year follow-up is an acceptable minimum follow-up length. Level of evidence Level III—retrospective analysis.

Background Anatomic total shoulder arthroplasty improves pain and function with a reported reoperation rate of approximately 1% per year. With improved glenoid fixation, reverse shoulder arthroplasty implants may outperform anatomic total shoulder arthroplasty. We evaluate the functional outcomes and reoperation rate of anatomic total shoulder arthroplasty versus reverse shoulder arthroplasty at a minimum eight-year follow-up or revision. Methods Between 2005 and 2010, 187 shoulders (137 anatomic total shoulder arthroplasty, 50 reverse shoulder arthroplasty) were retrospectively reviewed at a mean of 8.8 years. The mean age at surgery was 67 years. Females were more commonly treated with reverse shoulder arthroplasty. Both groups had similar body mass index and comorbidities. Outcome measures evaluated included abduction, forward elevation, external rotation, internal rotation, Simple Shoulder Test, Constant score, American Shoulder and Elbow Score, University of California Los Angeles Shoulder score, and Shoulder Pain and Disability Index. Results At follow-up, anatomic total shoulder arthroplasty demonstrated greater overhead range of motion and external rotation. All patient-reported outcomes remained similar between groups. Reverse shoulder arthroplasty patients were more likely to rate shoulders as much better or better after surgery (90% versus 67%, p = 0.004). Complications were observed in 24% of anatomic total shoulder arthroplasties and 8% of reverse shoulder arthroplasties (p = 0.02). Reoperation was more common in anatomic total shoulder arthroplasties (23% versus 4%, p = 0.003). Discussion At mid-to-long-term follow-up, reverse shoulder arthroplasties demonstrated significantly fewer complications and reoperations than anatomic total shoulder arthroplasties. Despite similar patient-reported outcomes, reverse shoulder arthroplasty patients were more likely to be satisfied with their shoulder.

Background Primary anatomic total shoulder arthroplasty can be challenging in patients with complex glenoid wear patterns and bone loss. Severe retroversion (>15°) or significant bone loss may require bone grafting. This review summarizes the rate of revision and long-term outcomes of anatomic total shoulder arthroplasty with bone graft. Methods A systematic search of MEDLINE, Embase, PubMed, and CENTRAL databases was conducted from the date of inception to 23 October 2018. Two reviewers independently screened articles for eligibility and extracted data for analysis. The primary outcome was rate of revision. The secondary outcomes were rate of component loosening, functional outcome, and range of motion. Results Of the 1056 articles identified in the search, 26 underwent full-text screening and 7 articles were included in the analysis. All procedures were one-stage anatomic total shoulder arthroplasties. The rate of revision was 5.4% with component loosening and infection listed as indications over a weighted mean follow-up period of 6.3 years. Complications occurred in 12.6% of patients. Conclusion Glenoid bone grafting in anatomic total shoulder arthroplasty results in comparable revision rates and improvement in pain compared to augmented glenoid components and reverse shoulder arthroplasty. Due to the low quality of evidence, further prospective studies should be conducted. Level of evidence IV

Background Deltoid muscle function is paramount to the success of reverse total shoulder arthroplasty. The purpose of this study was to investigate the role of deltoid volume on shoulder range of motion and patient-reported outcomes following reverse total shoulder arthroplasty in rotator cuff-intact and rotator cuff-deficient conditions. Methods Retrospective review of records identified 107 patients who met inclusion criteria. The rotator cuff integrity was evaluated by two musculoskeletal-trained radiologists. Volumetric deltoid measurements were calculated from preoperative computed tomography or magnetic resonance imaging scans. Satisfactory outcomes were defined as forward elevation of at least 135°, external rotation of at least 35°, and American Shoulder and Elbow Surgeons and Single Assessment Numerical Evaluation scores of at least 70. Results Mean total deltoid muscle volume was significantly higher in patients with satisfactory forward elevation (57.8 ± 18.1 cm³) versus unsatisfactory forward elevation (48.6 ± 19.5 cm³) (p = 0.013). When separated by rotator cuff integrity, total deltoid volume was significantly higher (p = 0.030) in patients who achieved satisfactory forward elevation in the rotator cuff-deficient group but not the rotator cuff-intact group (p = 0.533). Discussion Preoperative deltoid volume directly correlated with achieving satisfactory forward elevation after reverse total shoulder arthroplasty in rotator cuff-deficient conditions and may be one factor in determining the ability to achieve satisfactory outcomes in the rotator cuff-deficient patient.

Purpose Given the poor soft-tissue quality in rheumatoid arthritis patients, many believe that rheumatoid arthritis should be treated with reverse total shoulder arthroplasty (rTSA). The purpose of this paper is to systematically assess outcomes of anatomic total shoulder arthroplasty (aTSA) in rheumatoid arthritis to determine if aTSA remains a viable option. Methods A comprehensive literature search was conducted identifying articles relevant to aTSA in the setting of rheumatoid arthritis with intact rotator cuff. Outcomes include clinical outcomes and rates of complication and revision. Results Ten studies were included with a total of 279 shoulders with mean follow-up of 116 ± 69 months. The mean age was 68 ± 10 years. Survivorship was 97%, 97% and 89% at 5, 10 and 20 years, respectively. The overall complication rate was 9%. Radiolucency was present in 69% of patients, of which 34% were at risk of loosening at 79 months. The overall rate of revision was 8.4%. Studies generally reported clinically significant improvements in range of motion, Constant score and ASES score. Conclusion aTSA in the rheumatoid patient results in improvements in range of motion and patient-reported outcomes. Rates of complications and survivorship are generally good in this population. However, it should be noted that there is significant heterogeneity in outcome reporting amongst the literature on this topic and that many studies fail to adequately report complication and revision rates. When compared to rTSA in patients with rheumatoid arthritis, evidence suggests that aTSA is still a viable treatment option despite the shift in utilization to rTSA.

Abstract Purpose We aimed to compare the outcomes and complications of anatomical shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) for primary glenohumeral osteoarthritis with intact cuff tissue. Materials and methods The MEDLINE, Embase, and Cochrane Library databases were systematically searched for studies published before March 2, 2021 using the PRISMA guidelines. Studies were included if they directly compared aTSA and rTSA for treating primary glenohumeral arthritis. A meta-analysis was performed using six studies that compared radiologic outcomes, functional scores, and range of motion (ROM). All the data were pooled using a random-effects model. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated as dichotomous data, while continuous data were analyzed using mean differences with 95% CIs. Results Two independent researchers reviewed 1,061 studies. Six studies met the inclusion criteria. The range of motion, especially external rotation, was better for aTSA than for rTSA (MD = − 10.28, 95% CI: − 16.69 to − 3.88, P = 0.002). Functional scores showed no difference between aTSA and rTSA. Glenoid loosening (OR = 0.17, 95% CI: 0.06–0.50, P = 0.001) was more common with aTSA, and scapula notching (OR = 10.63, 95% CI: 1.73–65.27, P = 0.01) with rTSA. In the mid-term follow-up, the overall revision rate showed no difference between aTSA and rTSA, with a pooled OR of 0.33 (95% CI: 0.07–1.57, P = 0.16). Conclusion A better ROM was achieved after aTSA than after rTSA. There was no difference in the revision rate at mid-term follow-up between aTSA and rTSA. Glenoid loosening was more common with aTSA, and scapula notching with rTSA. Level of evidence: Level IV, Meta-analysis.

Background The purpose of this study was to describe the clinical outcomes following bilateral total shoulder arthroplasty (TSA). Methods A systematic search of the PubMed, Embase, and Cochrane Library databases following PRISMA guidelines was performed. English-language literature published from 2010 to 2018 analyzing bilateral TSA (anatomic and/or reverse) with a minimum one-year follow-up was reviewed by two independent reviewers. Study quality was evaluated with the Modified Coleman Methodology Score and the methodological index for non-randomized studies score. Results Eleven studies (1 Level II, 3 Level III, 7 Level IV) with 292 patients were included. Two studies reported on bilateral anatomic TSA ( n = 54), six reported on bilateral reverse TSA (RTSA; n = 168), two reported on anatomic TSA with contralateral RTSA (TSA/RTSA; n = 31), and one compared bilateral anatomic TSA ( n = 26) and bilateral RTSA ( n = 13). Among studies, mean revision rate ranged from 0% to 10.53% and mean complication rate ranged from 4.9% to 31.3%. At final follow-up, patients experienced significant overall improvements in range of motion and patient-reported outcome score measurements. However, bilateral anatomic TSA resulted in greater improvements in external rotation compared to bilateral RTSA. Overall patient satisfaction was 91.0%. Conclusion The available data indicate that bilateral TSA allows for functional and pain improvements and result in high patient satisfaction. Level of evidence IV.

Background: High rates of radiographic loosening have been reported with various glenoid designs. Many available designs sacrifice most of the bone at the central portion of the glenoid vault, creating large areas of deficiency when revision becomes necessary. The purpose of this study was to report the 2- to 5-year outcome of shoulder arthroplasty using a bone-preserving all-polyethylene glenoid components with self-pressurizing pegs. Methods: Between August 2011 and December 2014, 202 consecutive anatomic total shoulder arthroplasties (TSAs) were performed by a single surgeon with implantation of a self-pressurizing cemented pegged glenoid component in 190 patients (12 patients had both shoulders replaced). Patients were followed up prospectively and evaluated for pain, motion, strength, American Shoulder and Elbow Surgeons (ASES) scores, and radiographic changes. The mean follow-up time was 2.7 (2–5) years. Results: TSA improved pain and function reliably. At the most recent follow-up, 94% of the shoulders had no or mild pain. Motion included 154 ± 25° of elevation, 68 ± 18° of external rotation, and median internal rotation to T10 (range, iliac crest to T4). The most recent average ASES score was 82 ± 15 points. Early postoperative radiographs showed no radiolucent lines. No humeral or glenoid component was considered radiographically loose at the most recent follow-up. Complications requiring reoperation included subscapularis insufficiency (4), posterior instability (2), deep infection (1), stiffness (1), and a painful loose body (1). No components were revised for loosening. Conclusions: Anatomic TSA using a cemented bone-preserving all-polyethylene pegged self-pressurizing glenoid component provided satisfactory clinical outcomes and survival at 2 to 5 years.

Background No studies compare outcomes of anatomic total shoulder arthroplasty to reverse total shoulder arthroplasty with more than five-year follow-up. Methods A multicenter prospectively collected shoulder registry was utilized to review all patients undergoing primary anatomic total shoulder arthroplasty or primary reverse total shoulder arthroplasty with a minimum five-year follow-up utilizing a single platform stem implant system. One-hundred-ninety-one patients received an anatomic total shoulder arthroplasty and 139 patients received a reverse total shoulder arthroplasty. Patients were scored preoperatively and at latest follow-up using the simple shoulder test (SST), University of California Los Angeles (UCLA), American shoulder and elbow surgeons (ASES), Constant, and shoulder pain and disability index (SADI) scores as well as range of motion. Radiographs were evaluated for implant loosening or notching. Complications were reviewed. A Student’s two-tailed, unpaired t-test identified differences in preoperative, postoperative, and pre-to-postoperative improvements. Results Reverse total shoulder arthroplasty patients were significantly older than anatomic total shoulder arthroplasty patients. All patients demonstrated significant improvement in functional metric scores and range of motion following anatomic total shoulder arthroplasty or reverse total shoulder arthroplasty. There was no difference in final outcome scores between anatomic total shoulder arthroplasty and reverse total shoulder arthroplasty patients at midterm follow-up; however, reverse total shoulder arthroplasty patients demonstrated significantly less motion. Discussion We demonstrate equivalent outcomes with five scoring metrics at mean follow-up of 71.3 ± 14.1 months. Although postoperative scores were significantly greater than preoperative scores for both anatomic total shoulder arthroplasty and reverse total shoulder arthroplasty patients, significant differences in outcome scores between cohorts were not observed.

Purpose The purpose of this study was to evaluate the rate and risk factors for stiffness after reverse shoulder arthroplasty and the ramifications on the patient-reported outcomes. Method A consecutive series of patients who underwent reverse shoulder arthroplasty were prospectively followed for one year. Passive range of motion was measured preoperatively and at regular intervals postoperatively. Patients with passive forward elevation of less than 100° or passive external rotation of less than 30° were defined as stiff. Radiographic parameters and postoperative patient-reported outcome scores were collected. Results Seventy-six patients were available for review. The prevalence of postoperative stiffness following reverse shoulder arthroplasty was 47% at three months, 31% at six months, and 25% at one year. Preoperative shoulder stiffness was associated with three-month postoperative stiffness only. In patients with one-year stiffness, smaller ( p = 0.03) and less lateralized glenospheres ( p = 0.024) were more common. Stiffness was not associated with one-year patient-reported outcome scores. Conclusion Stiffness is common after reverse shoulder arthroplasty and often improves at one-year after surgery. Implant design and selection may be important determinants of passive range of motion. While stiffness does not appear to influence patient-reported outcome scores, one of four patients will potentially have stiffness one year following reverse shoulder arthroplasty. Level of evidence: Level III; retrospective study.

In reverse total shoulder arthroplasty stability is primarily controlled by the soft-tissue constraints rather than the congruency of the articulating surfaces. However, assessing the tension in these stabilizing structures currently remains highly subjective intra- operatively. In an attempt to quantify this feel during surgery, an intra-articular load sensor is introduced in this paper. In an in-vitro setting, the load sensor was used in eight reverse total shoulder arthroplasties on full torso specimens. The specimens were mounted on an inclined chair, such that the scapula could freely move to mimic surgical conditions. The resulting load vectors were captured through the range of motion under three different conditions, subjectively categorized by the surgeon as having a low, normal and high tightness. In neutral rotation and under a subjectively optimal condition assessed as neither too tight nor too loose, glenohumeral loads in the range of 10-20lbs were observed. For the same subjectively assessed optimal shoulder, loads up to 30lbs were observed under maximum internal/external humeral rotation. This contrasts the subjectively assessed loose and tight conditions, where lower resp. higher loads were observed that additionally affected the range of motion. On the other hand, stability was potentially missing under loose conditions as no increase in load was observed near the limits of the range of motion, indicating the lack of soft tissue restraint. In conclusion, this series of in- vitro experiments has shown the relevance and potential clinical value of assessing a shoulder’s stability and mobility using intra-articular load measurements during the trialing phase.
