The goal of this treatment was to allow im mediate mobilization of the knee with a single operative procedure. We also demonstrate a technique for de termining patellar position intraoperatively. Patients were tested for functional performance at an average final followup of 40 months (range, 20 to 66) including hamstring and quadriceps muscle strength evaluation, completion of a functional questionnaire, functional test performance, range of motion assessment, and patellar tendon length measurement. In evaluating the results, all cases were essentially identical to the nonoperated side, except one knee that had multiple associated liga ment injuries. The multitude of injuries to this knee are likely the cause of the discrepancy. Immediate midsub stance patellar tendon repair with semitendinosus aug mentation allowed immediate mobilization, which de creased the recovery period and improved the outcome of rehabilitation. Furthermore, a second surgery for hardware removal was not needed. These two factors\u2014 early and improved rehabilitation and the decreased chance of a second surgery\u2014affect the cost of treat ment of this injury. All isolated patellar tendon injuries in the study had excellent function at followup. For these reasons, we recommend this procedure for acute pa tellar tendon ruptures.<\/jats:p>","DOI":"10.1177\/036354659502300114","type":"journal-article","created":{"date-parts":[[2007,6,21]],"date-time":"2007-06-21T20:46:52Z","timestamp":1182458812000},"page":"82-86","source":"Crossref","is-referenced-by-count":79,"title":["Semitendinosus Augmentation of Acute Patellar Tendon Repair with immediate Mobilization"],"prefix":"10.1177","volume":"23","author":[{"given":"Roger V.","family":"Larson","sequence":"first","affiliation":[{"name":"University of Washington, Department of Orthopaedic Surgery, Seattle, Washington"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter T.","family":"Simonian","sequence":"additional","affiliation":[{"name":"University of Washington, Department of Orthopaedic Surgery, Seattle, Washington"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1995,1,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.3109\/17453677108989062"},{"key":"atypb2","doi-asserted-by":"crossref","unstructured":"Chekofsky KM , Spero CR, Scott WN: A method of repair of late quadriceps rupture .
