Distal hamstring tendon release in knee flexion deformity

SummaryHamstring tendon release was performed in thirty-one children for correction of true knee flexion deformity due to neurological disease. The long-term results in the thirty cases (55 knees) available for review were encouraging. Functional walking capacity and independence improved in nearly all cases. No complication occurred and there was no recurrence of the deformity despite an average follow-up period of five years. The results suggest that distal hamstring tendon release can be recommended in the management of true knee flexion deformity in selected cases of cerebral palsy and meningomyelocele.RésuméL'allongement des tendons des muscles ischio-jambiers a été réalisé chez 31 enfants pour la correction d'une attitude vicieuse du genou en flexion, causée par un déficit neurologique. Les résultats à long terme dans les trente cas (55 genoux) qui ont pu être revus étaient encourageants. La capacité fonctionnelle de la marche ainsi que l'indépendance des malades ont été améliorées dans presque tous les cas. Aucune complication n'a été constatée. Malgré une période moyenne de cinq années d'observation aucune récidive n'a été enregistrée. Ces résultats permettent de penser que l'allongement des tendons distaux des muscles ischiojambiers peut être recommandé pour traiter le flessum du genou dans des cas sélectionnés d'infirmité motrice cérébrale et de spina bifida.
