Abstract:
The goal of this study is to evaluate the functional results of the modified Judet quadricepsplasty for a knee extension contracture secondary to prolonged external fixation. This is a retrospective study of 31 patients with the diagnosis of an extraarticular knee extension contracture who had prolonged external fixation of the femur. Functional assessment was conducted after a minimum follow-up of 1 year. After performing the functional assessment, according to the Judet scale, 51% of the 31 patients had good results and 19.35% (6 cases) showed excellent results. The improvement in mobility from pre-operative to post-operative range of motion was significant. The performance of the technique, following the authors' described steps and making the subsequent modifications, allowed for partial knee mobility restoration, which significantly improved the patients' functional status.
Level Of Evidence:
IV. Series of cases.
