Abstract
BACKGROUND The optimal management of primary glenohumeral arthritis (GHOA) in the elderly is an ongoing topic of debate. The purpose of this study was to compare functional outcomes and complications in patients aged 75 years or older treated with anatomic total shoulder arthroplasty (TSA) or reverse shoulder arthroplasty (RSA) for primary GHOA with an intact rotator cuff. METHODS A retrospective study was performed on a prospectively maintained database which was queried for patients 75 years of age or older who underwent TSA or RSA for primary GHOA with an intact rotator cuff at a single institution between 2012 and 2021 with minimum 2-year follow-up. Patient-reported outcomes (PROs), including Visual Analog Scale for pain, American Shoulder and Elbow Surgeons, and Subjective Shoulder Value, as well as active range of motion including forward flexion, external rotation, internal rotation, were collected preoperatively and postoperatively. Complications, reoperations, and satisfaction were also recorded. The percentage of patients achieving clinically significant improvement was evaluated with the minimally clinical important difference, substantial clinical benefit, and patient acceptable symptomatic state for each PRO. RESULTS One-hundred and 4 patients were available for analysis, including 67 TSA patients and 37 RSAs with a mean follow-up of 39.4 months. Preoperative baseline characteristics, PROs, and range of motion were similar between groups. RSA was more commonly performed for eccentric glenoid wear (Walch B2/B3, 62% vs. 22%; P < .001). While clinical outcomes improved comparably in both groups, the TSA cohort showed significantly greater improvement in external rotation (36° vs. 26°; P = .013). Both cohorts had low revision (3% for TSA vs. 0% for RSA) and complication (7% for TSA vs. 5% for RSA; P = .677) rates. Satisfaction was similar in both groups (93% for TSA vs. 92% for RSA; P = .900). Clinically significant improvement was comparable between groups based on the American Shoulder and Elbow Surgeons score (minimally clinical important difference, 93% for TSA vs. 100% for RSA; substantial clinical benefit, 82% vs. 95%; patient acceptable symptomatic state, 67% vs. 78%; P > .05). CONCLUSION In this retrospective small sample size comparison study, TSA and RSA provide similar short-term clinical outcomes for patients 75 years and older with primary GHOA and an intact rotator cuff. Complication and revision rates are comparably low at short-term follow-up. Our data suggests that advanced age alone should not be used as a decision-making tool for TSA vs. RSA in the setting of primary GHOA with an intact rotator cuff.

Abstract
Background Newer generation humeral stem designs in total shoulder arthroplasty (TSA) are trending towards shorter lengths and uncemented fixation. The goal of this study is to report a 2-yr minimum clinical and radiographic outcomes of an uncemented short-stem press-fit humeral stem in anatomic total shoulder arthroplasty (ATSA) and reverse total shoulder arthroplasty (RTSA). Methods A retrospective multicenter database review was performed of all patients who received an uncemented short-length press-fit humeral stem (Equinoxe Preserve humeral stem, Exactech, Inc., Gainesville, FL, USA) in ATSA and RTSA with a minimum two-year follow-up. The primary outcome was the prevalence of humeral stems at risk of radiographic loosening. Secondary outcomes included evaluation of functional outcome scores and prevalence of revision TSA for humeral stem loosening. Two blinded observers performed radiographic analyses, which included humeral stem alignment, canal filling ratio, radiolucent lines, stress shielding (calcar and greater tuberosity), and changes in component position (subsidence and stem shift). At risk stems were defined by the presence of one or more of the following: humeral stem with shifting or subsidence, scalloping of the humeral cortex, or radiolucent lines measuring 2 mm or greater in 3 or more zones. Results 287 patients (97 ATSA and 190 RTSA) were included in this study. The mean follow-up was 35.9 (±6.1) months. There were significant improvements for all functional outcome scores (P < .05), range of motion (P < .05), and visual analogue pain scale pain (P < .05). The prevalence of humeral stem at risk of radiographic loosening was 1% in the ATSA group (1/97) and 18.4% in the RTSA group (35/190). Calcar resorption was seen in 34% of ATSA and 19% of RTSA, with severe resorption in 12.4% of ATSA and only 3.2% of RTSA. Greater tuberosity resorption was present in 3.1% of ATSA and 7.9% of RTSA. The mean canal filling ratio was 50.2% (standard deviation 11.2%). Using logistic regression, a significant positive correlation between canal filling ratio and stress shielding (P < .01) was seen for both calcar and tuberosity stress shielding. The revision surgery rate was 0% in ATSA compared to 1.6% in RTSA. Conclusion This retrospective study demonstrates a low revision rate and low prevalence of humeral stems at risk of radiographic loosening at two years with a press-fit short-stem humeral design in ATSA. Physiologic subsidence of humeral stems can account for higher prevalence of humeral stems at radiographic risk of loosening in RTSA compared to ATSA.

Abstract
Introduction This systematic review and meta-analysis compared the revision rates, complications, and outcomes in anatomic total shoulder arthroplasty (aTSA) and reverse TSA (rTSA) performed for primary glenohumeral osteoarthritis in patients aged over 70 years without a full-thickness rotator cuff tear. Materials and Methods We performed a systematic literature search identifying comparative studies meeting the above patient criteria and published from January 2010 to May 2022 from 3 databases: MEDLINE, EMBASE, and Cochrane Library. We performed the systematic review in accordance with PRISMA guidelines and the study was prospectively registered on PROSPERO. Results From the 1798 studies identified from the initial literature search, 4 met our inclusion criteria. Two thousand seven hundred thirty-one shoulder arthroplasties (1472 aTSA and 1259 rTSA) were evaluated with a minimum follow up of 2 years. A statistically significant lower revision rate was observed in rTSA compared to aTSA (odds ratio [OR] 0.50, 95% confidence interval [CI]: 0.30, 0.84, p < .05). No significant difference was noted between aTSA and rTSA in overall complication rate (OR 0.98, 95% CI 0.34, 2.86, p = .97) while aTSA displayed a statistically significant improved postoperative Constant-Murley score [aTSA: 80(75; 82), rTSA: 68(66; 76.5), p < .001]. Conclusion Higher revision rates were identified following aTSA in our study population, although admittedly this is within retrospective studies. aTSA displayed equal functional results and postoperative complications compared to rTSA in patients over 70 without a full-thickness rotator cuff tear. Given these similar results a shoulder surgeon must carefully consider each patient individually prior to deciding the optimal form of arthroplasty to offer.

Abstract
Background Both anatomic total shoulder arthroplasty (ATSA) and reverse total shoulder arthroplasty (RTSA) reliably improve pain and function for a variety of indications. However, there remain concerns about these procedures among elderly patients due to their general health, the potential for lesser functional gain, and the possible need for revision at an even older age. The purpose of this review is to compare the clinical outcomes, radiographic outcomes, and complications of ATSA and RTSA among patients older than 70 years. Methods A systematic review was performed using searches of PubMed, Embase, and Cochrane databases. The inclusion criteria were studies with patients older than 70 years who were treated with a primary ATSA or RTSA and clinical results reported at a minimum of 2 years. All indications for primary RTSA except for tumor were included. Outcomes of interest included patient-reported outcomes (PROs), range of motion, patient satisfaction, radiographic changes, complication and revision rates, and implant survival. Results A total of 24 studies met the inclusion criteria. At a mean follow-up of 3.4 years for ATSA and 3.1 years for RTSA, there were significant improvements in pain, range of motion, and PROs for both prostheses. Patients who underwent ATSA generally had better motion and functional outcomes compared to those who underwent RTSA, though these comparisons were made across different indications for arthroplasty. The satisfaction rate was 90.9% after ATSA and 90.8% after RTSA. Furthermore, 10.2% of ATSA patients and 9.9% of RTSA patients experienced a surgical complication, whereas 2.3% of ATSA and 2.2% of RTSA patients underwent a revision. Secondary rotator cuff tear was the most common complication after ATSA, occurring in 3.7% of patients, but only 1.1% of patients required revision surgery. Both ATSA and RTSA implant survivorship was reported to range from 93.1% to 98.9% at 5- and 8-year follow-up, respectively. Patient mortality was estimated to be 19.3% with a mean time to death of 6.1 years. Conclusions Elderly patients with primary osteoarthritis and an intact rotator cuff can have predictable pain relief, restoration of functional range of motion, and significant improvement in PROs after ATSA with low complication rates. Secondary rotator cuff failure and revision arthroplasty occur infrequently at early to mid-term follow-up. Although elderly patients who underwent ATSA generally had better functional outcomes compared to those who underwent RTSA for differing indications, patient satisfaction after both procedures were similar.

Baumgarten KM. Is stemless total shoulder arthroplasty indicated in elderly patients? J Shoulder Elbow Surg 2023; 32:260-268. [PMID: 36162630 DOI: 10.1016/j.jse.2022.08.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Revised: 07/24/2022] [Accepted: 08/03/2022] [Indexed: 02/01/2023]
Abstract
BACKGROUND AND HYPOTHESIS Stemmed anatomic total shoulder arthroplasty has represented the gold standard for the treatment of glenohumeral osteoarthritis with an intact rotator cuff for decades. To the author's knowledge, no study has specifically examined the outcomes of stemless, modular total shoulder arthroplasty in elderly patients. The hypothesis of this study was that stemless anatomic total shoulder arthroplasty in elderly patients (age ≥70 years) would have equivalent clinical and radiographic outcomes compared with a younger population (age <70 years). MATERIALS AND METHODS A prospectively collected database of patients undergoing primary, modular, stemless anatomic total shoulder arthroplasty for osteoarthritis was retrospectively reviewed. Patient-determined outcomes including the Western Ontario Osteoarthritis Index (WOOS) score, American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE) score, Simple Shoulder Test score, and Shoulder Activity Level score were recorded preoperatively and postoperatively at 1 year and 2 years. Preoperative and 1-year postoperative range of motion was recorded. Postoperative radiographs were examined to assess for radiographic evidence of complications. RESULTS Stemless arthroplasty was planned in 116 patients. Seven patients underwent conversion intraoperatively to a stemmed prosthesis. There was no difference between patients aged <70 yr and those aged ≥70 years who required intraoperative deviation from the preoperative plan to a stemmed prosthesis (5.8% vs 6.4%, P = .90). At the time of stemless arthroplasty, 64 patients were aged <70 yr and 44 patients were aged ≥70 years. Between the 2 groups, there were no clinically or statistically significant differences in WOOS, ASES, and SANE scores at baseline, 1-year follow-up, or 2-year follow-up. The changes in all scores from baseline to 2 years were similar between the group aged <70 yr and the group aged ≥70 years. There was no difference in the percentage of patients achieving the minimal clinically important difference or substantial clinical benefit in either group after shoulder arthroplasty at 2-year follow-up. There was no difference between the 2 groups in terms of final postoperative range of motion or change in range of motion for any metric examined. There was no evidence of radiographic complications in either group. CONCLUSIONS Age ≥70 years does not appear to be a contraindication to stemless anatomic total shoulder arthroplasty. Postoperative improvements in patient-determined outcome scores, the percentage of patients achieving clinically important outcomes for the ASES, SANE, and WOOS scores, and postoperative range of motion were similar between patients aged <70 yr and those aged ≥70 years. There was no difference between the groups regarding the patients who required intraoperative deviation from the preoperatively planned stemless prosthesis to a stemmed prosthesis. Neither age group demonstrated a radiographically apparent complication.
