대퇴 과간 절흔의 형성 부전과 전신적 인대 이완성을 동반한 소아의 습관성 슬개골 탈구에서 "four-in-one" 술식 : 예비 보고

Abstract

Purpose: To evaluate the clinical results of a “Four-in-One” procedure for a habitual dislocation of the patella in children with generalized ligamentous laxity and formation failure of the femoral trochlea. Materials and Methods: Five knees in 4 patients were included in this study. The average age of the patients at the time of surgery was 5.9 years and the subjects were followed up for an average of 41.6 months postoperatively. The clinical results were evaluated using the criteria of the Kujala's scoring system as well as a physical examination and radiological findings. Results: During the follow-up period, there were no recurrent dislocations, knee joint pain, limitations of motion or gait disturbances in any of the cases. The mean Kujala score was 96.8. Two cases had complications related to wound healing but they healed eventually. Conclusion: The "Four-in-One" procedure, which include the lateral retinacular release, medial vector augmentation, semitendinosus tenodesis, and patellar tendon transfer is recommended for a habitual dislocation of the patella in children with generalized ligament laxity and formation failure of the femoral trochlea.
