目的:研究复合软组织手术治疗不同年龄段儿童习惯性髌骨脱位的疗效。方法:2004年8月—2009年5月,采用复合软组织手术包括膝关节外侧充分松解、内侧紧缩、髌腱半腱止点移位和股内侧肌止点下移术治疗儿童习惯性髌骨脱位10例。术前及随访中分别行髌骨轴位和侧位X线检查,测量股骨滑车角,动态观察股骨滑车窝的形态和深度。结果:10例患儿均获随访,平均随访26个月(12～40)个月。末次随访时髌骨脱位均无复发,膝关节屈曲均能达135°～155°,膝关节无力症状明显改善,所有患儿均能参加正常的体育活动。结论:复合软组织手术对儿童习惯性髌骨脱位有较好的治疗效果。
Objective: To study the curative effect of compound soft tissue surgery on habitual patellar dislocation in children of different ages. Methods: From August 2004 to May 2009, children with habitual patellar dislocation were treated with complex soft tissue surgery including full lateral knee release, medial tightening, patellar tendon and semi-tendon only point shift, 10 cases. Preoperative and follow-up respectively patellar axial and lateral X-ray examination, measurement of femoral trochlear angle, dynamic observation of femoral trochlear nest shape and depth. Results: All the 10 children were followed up for an average of 26 months (ranged from 12 to 40) months. No recurrence of patellar dislocation at the last follow-up, knee flexion can reach 135 ° ~ 155 °, knee weakness symptoms improved significantly, all children can participate in normal physical activity. Conclusion: Composite soft tissue surgery has a good therapeutic effect on habitual patellar dislocation in children.
