There was no difference in joint laxity between repair techniques. Cyclic range-of-motion testing did not increase joint laxity at any tested joint angle. Strength to failure was no different between repair groups. Isometry was achieved in the TU and TN groups.</p><p><strong>Conclusions: </strong>All 4 techniques improved medial stability compared to that medial collateral ligament injury; however, no technique returned stability to the tarsal of the intact ligament. All 4 techniques maintained stability after range-of-motion testing. Isometric placement of the prosthetic suture was achievable. The constructs did not provide sufficient resistance to physiologic valgus stress.</p><p><strong>Clinical relevance: </strong>Isometric placement of a prosthetic ligament is possible; secondary stabilization appears necessary to support the repair postoperatively.</p>","PeriodicalId":7754,"journal":{"name":"American journal of veterinary research","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142520749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
