It is associated with adverse outcomes and morbidities. Studies on such complications are scarce in the literature. In this study, we share our experience in the management of four patients who sustained quadriceps tendon rupture in the early postoperative period. Efforts should be focused on prevention. Meticulous surgical techniques during the medial parapatellar approach to preserve the integrity of quadriceps can reduce the risk of rupture. The importance of prompt diagnosis is emphasized as delayed treatment may lead to poor outcomes. However, making a diagnosis can be challenging, as worsening of the quadriceps strength after TKA is expected because of the surgical approach that violates the quadriceps muscle. In an event of postoperative trauma with resultant extensor weakness, an ultrasound evaluation to exclude a quadriceps tendon rupture should be promptly performed after a fracture is excluded.<\/jats:p>","DOI":"10.1177\/2309499017717206","type":"journal-article","created":{"date-parts":[[2017,11,7]],"date-time":"2017-11-07T09:37:11Z","timestamp":1510047431000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Disruption of quadriceps tendon after total knee arthroplasty: Case report of four cases"],"prefix":"10.1177","volume":"25","author":[{"given":"JW","family":"Soong","sequence":"first","affiliation":[{"name":"Singapore General Hospital, Singapore, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"AN","family":"Silva","sequence":"additional","affiliation":[{"name":"Singapore General Hospital, Singapore, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tan HC","family":"Andrew","sequence":"additional","affiliation":[{"name":"Singapore General Hospital, Singapore, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2017,7,12]]},"reference":[{"issue":"17","key":"bibr1-2309499017717206","first-page":"1349","volume":"271","author":"Callahan CM","year":"1994","journal-title":"A meta-analysis.
