The position of the patellar component and patellofemoral symptoms were assessed in a series of 72 cemented polyethylene patellar components in total condylar arthroplasties. A small (25 mm) component was used. The minimum follow up was 2 years and maximum 3 years. A lateral retinacular release was carried out in 22 knees. Clinical results were assessed by questionnaire and 86% had no patellofemoral symptoms. The mean postoperative patellar height was not changed compared to the preoperative height. Lateral placement of the patellar component was associated with both increased medial tilt and lateral subluxation. The component should be inserted so that its centre is slightly medial to the centre of the bone.
在一系列全髁关节成形术中，对72个骨水泥固定的聚乙烯髌骨关节组件的位置及髌股关节症状进行了评估。使用的是小型（25毫米）组件。最短随访时间为2年，最长为3年。22例膝关节进行了外侧支持带松解。通过问卷调查评估临床结果，86%的患者无髌股关节症状。与术前相比，术后髌股关节平均高度未发生变化。髌骨组件的外侧放置与内侧倾斜增加和外侧半脱位均有关。组件插入时应使其中心略位于骨中心的内侧。
