Abstract

Prolonged immobilization of the knee after repair of the patellar tendon can result in decreased patellar mobility, limited flexion, persistent pain, muscle weakness, and patella infra. In contrast, early motion prevents many of these unwanted effects. We evaluated the outcome of surgical repairs augmented by a distally based semitendinosus autograft to allow early mobilization. Between January 2010 and October 2010, 15 patients with patellar tendon ruptures were admitted; their average age was 37 years (range, 28–53). By 6 weeks after surgery, 120 degrees of flexion and brace-free ambulation were reached in most patients. By 6 months, most patients had recovered their preinjury levels of activity. At a minimum follow-up of 24 months, results of surgical repair were assessed with the Lysholm scoring. Five cases were excellent, nine cases were good, and one case was poor. Patella tendon repair augmented by semitendinosus tendon was strong enough to permit early motion and weight bearing with achievement of good and excellent results.
