Results of supracondylar femoral extension osteotomy and patellar tendon advancement in patients with cerebral palsy

Purpose: knee flexion contracture and patella alta are common problems in cerebral palsy (cp) patients and disrupts gait function significantly. supracondylar femur extension osteotomy (sfeo) and patellar tendon advancement (pta) are among the leading treatment methods. we reviewed the efficacy of sfeo and pta in the treatment of knee flexion contracture and patella alta of cp patients. materials and methods: in this retrospective study 22 hips of 11 cp patients who were operated between 2013 and 2015 were reviewed. the mean age was 13 years when the patients were operated and the mean follow-up period was 31 months. sfeo and pta were peroformed in all cases. patients were evaluated clinically with gross motor function classification system (gmfcs) and recurrence of knee flexion contracture and radiologically with knee radiograph. the koshino-sugimoto index (ks) was recorded. results: gmfcs scores were improved in seven patients. recurrence of knee flexion contracture was detected in one case who was treated with revision sfeo. the mean preoperatively ks was 1.37; postoperatively ks was 1.07 and follow-up 1.24 (p=0.004). cerclage wire irritation was detected in two cases and extracted with additionally surgical procedures. conclusion: reconstruction of knee flexion contracture and patella alta in cp patients with sfeo and pta provides successful clinical and radiological results.
