摘　　要：目的评价髌腱内移和髌内侧筋膜肌肉瓣外移术治疗先天性髌骨脱位的效果。方法自1994年6月～1998年6月,采用髌腱内移和内侧筋膜肌肉瓣外移的方法治疗先天性髌骨脱位5例,男2例,女3例,平均年龄7岁(4～10岁)。4例为单侧髌骨脱位,1例为双侧(只治疗一侧),均未合并其它畸形。结果术后随访1.5～5年,平均3年,无手术并发症,无术后再脱位和半脱位。4例膝关节能完全伸直,1例差10°;2例膝外翻消失;1例10岁女童术后出现髌骨低位,但膝外翻消失、功能正常且伸膝有力。结论先天性髌骨脱位是一种持续、不可复性脱位,需手术治疗。髌内侧筋膜肌肉瓣外移和髌腱内移术操作简单,损伤较小,并发症少,效果优良,是一种值得推荐的手术方法。Objective Congenital dislocation of the patella is rare and produces varying degrees of knee disability with the growth of the child. It should be managed as soon as the diagnosis is made. The purpose of this paper is to describe the procedure and to assess the results of congenital dislocation of patella treated with medial transfer of patellar tendon and lateral transfer of medial fascio muscular flap. Methods Five children with congenital dislocation of patella were treated with medial transfer of patellar tendon and lateral transfer of medial fascio muscular flap between June 1994 and June 1998. There were two boys and three girls. The age of the patients at the surgery varied from 4 to 10 years. Four of them were unilateral and one was bilateral without any other deformities. An S-shaped incision is made to expose the distended medial fascio muscular flap, dislocated patella and well developed vastus medialis. The patellar tendon is detached from its insertion and released from the surrounding retinacula. A hole corresponding to the width of the patella is made in the membrane and another one is made through the synovial membrane and the fibrous capsule. The patellar tendon was sutured into the hole in the tibial metaphysis through the two membrane holes. The iliotibial band was lengthened and the biceps tendon was turned over the abundant medial retinaculum with a part of the vastus medialis to the lateral side of the synovial membrane. The patient was kept in a long leg cast and immobilized for 6 weeks. Results The average period of follow up was three years(range, one year and six months to five years). Four cases were able to extend the knee completely and one case had minus ten degrees in extention. Knee valgus in two patients disappeared after operation and one had a lower patella, but the function of knee was normal without any symptoms and signs. There were no complications in this series. Conclusion The patients with congenital dislocation of patella which is permanent and irreducible must be i
