手术技术和植入物设计影响全膝关节置换术中股骨髁提离。通过使用骨切除和适当软组织松解的经典方法，股骨部件沿经上髁轴沿着对线将产生对称和平衡的屈曲空间。这种手术技术将减少髁突抬离的发生率。如果髁突确实发生抬离，使用设计为符合前关节的假体可能是有益的。通过相对一致的关节减少抬离，减少边缘载荷，进而减少聚乙烯损坏。
The surgical technique and implant design influence femoral condylar lift-off in total knee arthroplasty. With the use of the classic method of bone resection and appropriate soft tissue releases, alignment of the femoral component along the transepicondylar axis will create a symmetric and balanced flexion space. This surgical technique will reduce the incidence of condylar lift-off. If condylar lift-off does occur, it may be beneficial to have a prosthesis that is designed with a conforming frontal articulation. Reducing lift-off with a relatively conforming articulation reduces edge loading and in turn should reduce polyethylene damage.
