Coronoidectomy was performed and the arthroplasty was accomplished at the level of the condylar neck. 方法是在頰棚作切線(xiàn)，翻開(kāi)軟組織，將喙狀突切斷，撥到內側，然后在髁頸的高度進(jìn)行關(guān)節成形術(shù)。
Arthroscopic assessment can be helpful, but there are no data to indicate whether it is necessary before patellofemoral arthroplasty. 關(guān)節鏡檢評估可能有用，但是沒(méi)有數據表明髕骨股骨關(guān)節成形術(shù)前是否有必要。
