{"title":"Why Do Lateral Unicompartmental Knee Arthroplasties Fail Today?","authors":"Jelle P van der List, Hendrik A Zuiderbaan, Andrew D Pearle","doi":"","DOIUrl":"","url":null,"abstract":"In large studies, the failure modes of lateral unicompartmental knee arthroplasty (UKA) are usually presented in combination with medial UKA, which is mainly due to low surgical frequency of lateral UKA. Because lateral UKA differs from medial UKA in anatomic and kinematic characteristics, failure modes of lateral UKA should not be presented in combination with medial UKA. Therefore, we performed a systematic review to assess failure modes in lateral UKA and compared failure modes in cohort studies with those found in registry-based studies. A search performed in PubMed, Embase, and Cochrane identified 25 studies (23 cohort studies and 2 registry-based studies) that were eligible in presenting failure modes in lateral UKA. Most common failure modes in lateral UKA were progression of osteoarthritis (OA; 29%), aseptic loosening (23%), and bearing dislocation (10%). In cohort studies, progression of OA was more common (36%) than bearing dislocation (17%) and aseptic loosening (16%), while in the registry-based studies, aseptic loosening (28%) was more common than progression of OA (24%) and bearing dislocation (5%). In conclusion, progression of OA is the most common failure mode in lateral UKA. In the future, both cohort studies and registry-based studies should report the failure modes of medial and lateral UKA separately.","PeriodicalId":520912,"journal":{"name":"American journal of orthopedics (Belle Mead, N.J.)","volume":"45 7","pages":"432-462"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144510632","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}

However, there is minimal literature on isolated teres major (TM) and latissimus dorsi (LD) injuries. As a result, there is no consensus on an optimal treatment method. An extensive Medline search on studies focusing on the treatment of isolated LD and TM injuries in professional baseball pitchers was performed to explore this topic. Of the 20 retrieved articles, 5 met our inclusion criteria. There were a total of 29 patients who underwent conservative treatment and 1 who underwent surgical treatment. The average time required to return to pitching was 99.8 days in the conservative group and 140 days in the surgically treated group. Five patients in the conservative group suffered from complications and/or setbacks during their treatment and rehabilitation. The lone surgical patient suffered no complications, returned to preinjury form, and was elected an all-star the following year. The goal of this review is to provide a concise summary of the current literature in order to assist physicians when discussing treatment options with their patients.

{"title":"Pigmented Villonodular Synovitis of the Hip: A Systematic Review.","authors":"David M Levy, Bryan D Haughom, Shane J Nho, Steven Gitelis","doi":"","DOIUrl":"","url":null,"abstract":"Pigmented villonodular synovitis is a rare proliferative condition of the synovium that affects large joints. The primary treatment options are synovectomy and a combination of synovectomy and arthroplasty. We performed a systematic review of the literature, excluding all nonclinical and review articles with follow-up of less than 2 years. Primary outcomes reported were disease recurrence, symptom progression, and revision surgery. Student t tests were used to compare outcomes after synovectomy with outcomes after synovectomy combined with arthroplasty. Twenty-one studies (82 patients) were included. All represented level IV or V evidence. Fifty-one patients (59.3%) were female. Mean (SD) age was 33.2 (12.6) years. Synovectomy alone was performed in 45 patients (54.9%), and synovectomy with arthroplasty was performed in 37 patients (45.1%). Mean (SD) follow-up was 8.4 (5.9) years. The groups' revision rates were not significantly different (26.2% vs 24.3%; P = .17). Mean (SD) time to revision was significantly (P = .02) longer in the synovectomy-with-arthroplasty group, 11.8 (4.5) years, than in the synovectomy-only group, 6.5 (3.9) years. Study results showed revisions are common after surgery for hip pigmented villonodular synovitis, affecting 1 in 4 patients regardless of which surgery they have-either synovectomy alone or synovectomy combined with arthroplasty. Revision is required sooner in synovectomy-only patients than in patients who also undergo arthroplasty.","PeriodicalId":520912,"journal":{"name":"American journal of orthopedics (Belle Mead, N.J.)","volume":"45 1","pages":"23-8"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144510633","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}
