Lateral instability of the patella was found after recurrent, habitual and permanent dislocations. Contracture of soft tissues lateral to the patella only occurred with habitual and permanent dislocations, but medial laxity was present in all cases. After adequate release of the lateral contracture, the medial stability was improved by transposition of the lower three-quarters of the pes anserinus to the medial border of the patella, and the patellar ligament. This created a relatively unstretchable physiological sling which ensured dynamic stability of the patella. Six recurrent, 21 habitual and nine permanent dislocations of the patella were treated by this method. Results were excellent in 21 patients, good in 13 and fair in two. The follow-up period varied from 21 to 84 months. There have been no recurrences to date.
髌骨反复性、习惯性及永久性脱位后可出现髌骨外侧不稳定。仅在习惯性和永久性脱位时出现髌骨外侧软组织挛缩，但所有病例均存在内侧松弛。在充分松解外侧挛缩后，通过将鹅足的下四分之三移位至髌骨内侧缘及髌韧带，内侧稳定性得到改善。这形成了一个相对不可拉伸的生理性吊带，确保了髌骨的动态稳定性。采用该方法治疗了6例复发性、21例习惯性和9例永久性髌骨脱位。21例患者效果优良，13例良好，2例尚可。随访时间为21至84个月。迄今为止，无复发情况。
