Bilateral knee radiographs may demonstrate patella alta with patellar tendon tears and patella baja with quadriceps tendon tears compared with the uninjured knee. Ultrasound and magnetic resonance imaging can be helpful when there is uncertainty in the diagnosis. Surgical treatment is indicated for complete tears and some high\u2010grade, partial tears. Nonabsorbable high\u2010strength sutures or suture tape are placed in running locking fashion along the injured tendon and secured to the patella with bone tunnels (i.e., transosseous) or suture anchors. The transosseous technique requires exposure of the length of the patella to drill 3 bone tunnels to shuttle the sutures and tie over either pole of the patella. The suture anchor technique allows for a smaller incision and less soft\u2010tissue dissection and may use a knotted or knotless technique. Biomechanical testing with load to failure is not statistically different between the transosseous and anchor techniques, although anchors have been shown to have less gap formation at the repair site. Repair augmentation with a graft may be beneficial in mid\u2010substance injuries, chronic tears, and in cases of compromised tissue quality. Rehabilitation usually can be initiated immediately with protected weight\u2010bearing in an orthosis, safe\u2010zone knee passive range of motion, and avoidance of active extension. After a period of 6 weeks, rehabilitation can progress with full range of motion and a concentric strengthening program.<\/jats:p>","DOI":"10.1016\/j.arthro.2022.10.034","type":"journal-article","created":{"date-parts":[[2022,11,1]],"date-time":"2022-11-01T21:29:46Z","timestamp":1667338186000},"page":"142-144","update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":20,"title":["Repair
