RésuméLe but de cette étude est de rapporter les résultats de la chirurgie mobilisatrice du genou dans le cadre des reconstructions par prothèse pour tumeur musculosquelettique chez l’enfant et l’adolescent. Dix-neuf patients opérés d’une résection tumorale avec reconstruction par prothèse massive du genou ont subi une intervention mobilisatrice pour raideur. Les patients ont été revus cliniquement à un recul moyen de cinq ans (un à 20 ans). Le gain moyen en amplitude était de 80° (± 24). Trois patients ont eu une récidive complète de la raideur. La libération chirurgicale est principalement indiquée en cas de cause identifiée de la raideur chez un patient motivé. Les résultats de cette chirurgie associée à une rééducation bien conduite sont alors satisfaisants.
SummaryPurpose of the studyImproved oncologic outcome and technical advances in limb salvage surgery have made limb salvage therapy a feasible and valuable treatment option. Nevertheless, resection of a bone tumor followed by a reconstruction knee endoprosthesis can create gait abnormalities, of which one of the most frequent is knee stiffness. The aim of this retrospective study was to assess the outcomes of revision surgery for a stiff knee following reconstruction of a segmental long bone defect.Patients and methodsBetween 1983 and 2005, 19 patients who had undergone wide resection of a tumor close to the knee followed by reconstruction with a massive endoprosthesis were revised for a diagnosis of stiffness.ResultsThe mean age of the patients was 12 years (range: 7–19 years). Patients were followed for a mean five years (range: 1–21 years). Three patients were not assessed at the last follow up (two patients died, one patient was amputated for a local recurrence). The mean range of motion improved 80 ± 24° preoperatively to postoperatively. The Enneking score improved from 15 ± 0.5 to 23 ± 3 points at three months follow-up, and to 22 ± 5 at last follow-up. Recurrent stiffness occurred three times and required a second operative release with a good final result.DiscussionOutcome depends on the cause of the stiffness of the reconstruction knee arthroplasty. Stiffness can be caused by complications (trauma, implant failure, infection), and patient-related factors (lack of physiotherapy). Open arthrolysis is indicated for chronic stiffness in a motivated patient with an identified cause because failure to identify the cause of stiffness may result in recurrence of the problem.
