Aseptic loosening of the glenoid component, however, is a major cause for revision. Hybrid components have been introduced, combining traditional cemented fixation with porous titanium bone ingrowth to improve fixation. The purpose of this study was to report our midterm to longterm experience using such a component, including clinical outcomes and implant survival.</div></div><div><h3>Methods</h3><div>We reviewed all patients who were operated for primary osteoarthritis during the period 2011-19, leaving a minimum of 2-year follow-up. The severity of the osteoarthritis was graded using Samilson-Prieto score, while glenoid morphology was graded using the modified Walch classification. Clinical outcomes included Western Ontario Osteoarthritis of the Shoulder (WOOS) index, EQ-5D-5L, and Constant-Murley score. Postoperative radiographs were analyzed for radiolucent lines. Patient records were studied for complications including revisions. Supplementary data for revision and outcome were obtained from the Danish Shoulder Arthroplasty Registry. Kaplan-Meier estimates for implant survival were calculated.</div></div><div><h3>Results</h3><div>A total of 256 arthroplasties in 224 patients were included (mean age: 69 years ± 9 years, 149 females). 81% of cases were graded radiographically as severe osteoarthritis, according to Samilson-Prieto. Walch type B1 was most commonly followed by B2 (29% and 28% respectively). The mean follow-up time was 49 months (range 24-127). The response rate for patient reported outcomes was 91%. The median WOOS index was 94% (81%-99%), the median EQ-5D-5L was 0.87 (0.69-0.95), and the mean Constant-Murley score was 75 (SD 17.7). 13 cases (6%) had a WOOS index below 50%. 8.2% had complications related to surgery. A radiolucent line had developed around the central post in six cases and at the bone-cement interface in three cases at follow-up. Six cases had been revised (2.3%); three due to aseptic loosening of the glenoid.

The 10-year survival rate is high and comparable to that reported for the best- performing all-polyethylene components.

Patient demographics, laboratory data, history of COVID-19 infection and vaccination, antibiotic treatment, and final surgical treatment were collected. Patient-reported outcome measures (American Shoulder and Elbow Surgeons Shoulder Score, Single Assessment Numeric Evaluation, surgical Apgar score, Patient-Reported Outcome Measurement Information System (physical function, pain intensity, upper extremity, global 10), and Veterans RAND 12-item Health Survey or Medical Outcomes Study short-form health survey version 2) were collected.

Preoperative planning utilized e-ORTHO templating software (FH Orthopaedics, Mulhouse, France), ensuring uniform lateralization shoulder angle and distalization shoulder angles across groups. Primary outcomes included range of motion (ROM), while secondary outcomes comprised Constant Score (absolute/ponderate), subjective shoulder value (SSV), and visual analog scale (VAS). Discrepancies in scores between groups were evaluated for clinical relevance against minimal clinically important difference benchmarks. Incidences of scapular notching were also recorded.</div></div><div><h3>Results</h3><div>All the clinical parameters analyzed were improved postoperatively in both groups (<em>P</em> &lt; .05). No significant difference was observed in postoperative ROM, ponderate Constant, and VAS between groups (<em>P</em> &gt; .05) except for forward elevation which was higher in the taller group (142.9 ± 27.6 compared to 163.5 ± 11.1 <em>P</em> = .018). For SSV, the taller group had higher postoperative SSV (<em>P</em> = .037). However, the difference was less than the minimal clinically important difference for SSV (−5.97 [95% confidence interval: −10.17 to 1.76], <em>P</em> = .01) and thus was considered not clinically significant. No scapular notching was detected in either group.</div></div><div><h3>Conclusion</h3><div>When planned positioning angles are respected (lateralization shoulder angle, distalization shoulder angle), the benefits of highly lateralized rTSA are consistent regardless of patient stature.

Failure of the LTO repair has been associated with poorer outcomes, decreased patient satisfaction, and the potential need for revision arthroplasty. Despite this, few studies closely examined outcomes for revision LTO repair in the setting of prior TSA.</div></div><div><h3>Methods</h3><div>A retrospective review of all TSAs performed by a single surgeon from 2016 until 2023 was performed to identify all cases with LTO failure who underwent acute revision LTO repair. Baseline characteristics, postoperative complications including infection, need for revision surgery, and time to revision surgery were collected and reported on all TSA patients. All patients were followed for a minimum of 1 year after their TSA and revision LTO fixation if required. Subgroup analysis was performed on the LTO revision cohort to evaluate for potential risk factors.</div></div><div><h3>Results</h3><div>A total of 166 patients underwent TSA with LTO. Of these, eight patients were diagnosed with an acute LTO failure at a mean of 5.7 weeks after surgery and underwent revision LTO fixation at a mean of 6.3 weeks after surgery. At a mean follow-up of 147.9 weeks (standard deviation: 90.3; range: 52.1-284.9), seven of eight patients (87.5%) demonstrated healing of their LTO and had no complaints, complications, or reoperations at the latest follow-up. One patient developed a periprosthetic infection requiring two-stage revision. No patients in the overall cohort underwent revision shoulder arthroplasty due to subscapularis failure.</div></div><div><h3>Conclusion</h3><div>Early identification of subscapularis failure is important to optimize outcomes of revision fixation. Use of LTO for subscapularis repair is beneficial by allowing early radiographic detection of subscapularis failure. Revision LTO repair can be successful when performed acutely and appears to minimize the need for revision shoulder arthroplasty due to subscapularis failure.</div></div>","PeriodicalId":39885,"journal":{"name":"Seminars in Arthroplasty","volume":"35 1","pages":"Pages 48-55"},"PeriodicalIF":0.0,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143284926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
