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 degrees (range 10 degrees -50 degrees ). At the final follow-up the mean active flexion was improved to 100 degrees (range 70 degrees -130 degrees ) with an average flexion gain of 70 degrees (range 45 degrees -100 degrees ). 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.
