Superior dislocation of the patella is an uncommon condition that mainly occurs in knees with a high patella and medial femorotibial degenerative arthritis. There are no previous reports of this condition occurring in association with tibial valgus osteotomy.
We report the case of a patient in whom vertical dislocation recurred twice at 4 months after tibial valgus osteotomy. To avert additional recurrence or new dislocations, the patient was treated surgically to remove the existing osteophytes.
An arthroscopic approach was decided because of the lower associated morbidity and good results with this technique compared to open surgery.
髌骨上脱位是一种罕见的病症,主要发生于高位髌骨和股胫内侧退行性关节炎的膝关节。此前尚无该病症与胫骨外翻截骨术相关的报道。
我们报告了1例患者,其在胫骨外翻截骨术后4个月垂直脱位复发了2次。为避免再次复发或出现新的脱位,对该患者进行了手术治疗以去除现有的骨赘。
由于与开放手术相比,关节镜手术相关发病率较低且效果良好,因此决定采用关节镜手术方法。
