Every knee has its individual envelope of motion. The joint surfaces, the ligaments and the articular capsule determine the range of motion. In walking, stability is mainly provided by the muscles. Malalignment is the usual reason for failure in knee replacement with PCA prostheses. Preoperative planning is essential for operative success.
每个膝关节都有其独特的活动范围。关节面、韧带和关节囊决定了活动范围。在行走时，稳定性主要由肌肉提供。对线不良是PCA假体膝关节置换失败的常见原因。术前规划对手术成功至关重要。
