The disarticulation of the knee joint is--in contrary to the above-knee level--a fast and tender method for amputation, resulting in a vigorous, complete weightbearing stump. Without problems the bulky stump is fitted in an exactly moulded plastic or resin socket--eventually combined with a soft socket--, which can be easily put on and off also by older patients suffering from general dysvascular disorders. Nowadays special joints are used for functionally as well as cosmetically satisfying knee-disarticulation-prostheses. The surgical technique with alternative incisions, the peculiarities in dysvascular patients, the postoperative care including immediate or early fitting, the management after wound-healing with a temporary exercise-prosthesis and finally the various possibilities of the definitive prosthetic fitting are stressed in detail.
与膝上截肢不同，膝关节离断术是一种快速且创伤小的截肢方法，能形成有力、可完全负重的残端。粗大的残端能毫无问题地适配精确塑形的塑料或树脂接受腔——最终可结合一个软质接受腔——即便患有全身性血管疾病的老年患者也能轻松穿脱。如今，特殊关节被用于制造功能和外观都令人满意的膝关节离断假肢。文中详细强调了采用替代切口的手术技术、血管疾病患者的特殊情况、术后护理（包括立即或早期适配）、伤口愈合后使用临时运动假肢的处理，以及最终确定假肢适配的各种可能性。
