Modified Judet's quadricepsplasty for loss of knee flexion

We reviewed the results of a modified Judet's quadricepsplasty in eleven patients with inability to fully flex the knee. The patients were examined at an average follow-up of 49 months (4 to 108 months). Their mean pre-operative knee flexion was 30° (range 10°–50°). At the final follow-up the mean active flexion was improved to 100° (range 70°–130°) with an average flexion gain of 70° (range 45°–100°). None of the patients developed an extension lag. According to Judet's criteria, the results were three excellent, seven good and one fair. Staged quadricepsplasty is a useful procedure to correct the disabling flexion loss in the knee.
