Fifteen knees with patellar dislocation after total knee arthroplasty had realignment of the extensor mechanism using a modification of the Trillat procedure. The onset of dislocation occurred on average 4.7 months from the time of surgery. After total knee arthroplasty the patients had an average range of motion of 109 degrees. All patients had medialization of the tibial tubercle and lateral release. No patient had a recurrent dislocation after a minimum 2-year follow-up period. The average knee score was 82 and the average flexion arc was 112 degrees. All but one of the osteotomies healed uneventfully.
15例全膝关节置换术后发生髌骨脱位的患者，采用改良的Trillat手术对伸肌机制进行了重新排列。脱位平均发生在术后4.7个月。全膝关节置换术后患者的平均活动范围为109度。所有患者均进行了胫骨结节内移和外侧松解。经过至少2年的随访，无患者出现复发性脱位。平均膝关节评分为82分，平均屈曲弧度为112度。除1例外，所有截骨均顺利愈合。
