Rupture of the knee extensor mechanism may occur because of a forceful eccentric contraction of the quadriceps against a resisted flexed knee, though atraumatic cases have also been described. Patients at higher than normal risk for knee extensor mechanism rupture include those with systemic co-morbidities, fluoroquinolone use, and chronic tendinopathy. Early operative treatment and mobilization of acute extensor mechanism ruptures has proven effective, and numerous techniques have been described. A 46-year-old male on anastrozole therapy simultaneously ruptured his left patellar and right quadriceps tendons during a deadlift attempt. Diagnosis was by history and physical examination. Repair of both injuries was performed 5 days after injury. Described within and shown in the accompanying video is a standard technique for primary repair using Krackow stitches through the ruptured tendon that are passed through patellar bone tunnels and tied over a bone bridge. The finer points of this technique are emphasized. Also included is a technique to augment the standard repair with a figure-of-8 stitch passed through additional oblique patellar bone tunnels. The mechanical advantage of the adjuvant figure-of-8 stitch provides additional compression, which nicely reapproximates the tendon edges.<\/jats:p>","DOI":"10.1097\/bot.0000000000000604","type":"journal-article","created":{"date-parts":[[2016,7,23]],"date-time":"2016-07-23T02:09:35Z","timestamp":1469239775000},"page":"S30-S31","source":"Crossref","is-referenced-by-count":24,"title":["Knee
