The typical injuries for swimmers were muscular chronic injuries at spine region，rotator cuff injury，anterior talofibular ligament injury，and patellar enthesiopathy.

最为常见的游泳创为腰肌、肩袖、距腓前韧、髌腱末端病等。

Results The patients were followed up from 3 months to 2 years, no patellar redislocation was found, and excellent and good rate was 75%.

结果随访3个月～2年,者关节功能好,髌骨脱位无复,率75%。

Rotational alignment of the trochlear component parallel to the epicondylar axis optimizes patellar tracking.25,26 Palpation of the epicondyles is difficult, particularly when using smaller incisions.

与上踝轴平行的滑车成分旋转位移能使髌骨痕迹最化25.26。上踝触诊很难，特此是使用小切口时。
