15例全膝关节置换术后髌骨脱位的膝关节采用Trillat手术改良进行伸肌机制重新对线。脱位发生在手术后平均4.7个月。全膝关节置换术后，患者的平均活动度为109度。所有患者均行胫骨结节内侧化和外侧松解。在至少2年随访期后，没有患者复发脱位。平均膝关节评分为82分，平均屈曲弧度为112 °。除1例截骨术外，所有截骨术均顺利愈合。
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.
