The total knee replacement concerns patients with large functional impairments of this joint. The most common in use now is total nonconstrained knee prosthesis.
Twenty-five patients underwent total knee replacement between 1987-1997. For twelve patients the cause of treatment was RA, for thirteen it was the implication of idiopathic osteoarthritis of the knee. The mean age of the patient during the operation was 60 years (range 27 to 78 years). The mean follow-up of knee replacement was 13 years. We based our outcome evaluation on clinical (WOMAC, KSS) and radiological evaluation.
The average preoperative KSS score for the group of patients was 40, WOMAC score--95. After an average of 13 years follow-up all knees were considered excellent, with average KSS score of 98, WOMAC score of 30. All patients had increased function and decreased pain. The radiograms of all patients revealed that the femoral and tibial components of the prosthesis were correctly positioned with no radiographic evidence of loosening in the last examination.
Clinical and radiological evaluation of our material showed that total knee replacement allows regaining good lower limb function for the long time, which helps the patients staying less dependant on the surrounding environment. The above appears to occur regardless of the primary diagnosis which was the indication for operation.
全膝关节置换术适用于该关节功能严重受损的患者。目前最常用的是全非限制性膝关节假体。
1987年至1997年间，25例患者接受了全膝关节置换术。其中12例患者的治疗原因是类风湿关节炎（RA），13例是特发性膝关节骨关节炎。手术时患者的平均年龄为60岁（范围27至78岁）。膝关节置换术后的平均随访时间为13年。我们基于临床（WOMAC、KSS）和影像学评估来评价结果。
该组患者术前KSS平均评分为40分，WOMAC评分为95分。平均随访13年后，所有膝关节均被认为效果极佳，KSS平均评分为98分，WOMAC评分为30分。所有患者的功能均有所改善，疼痛减轻。所有患者的X线片显示，假体的股骨和胫骨部件位置正确，在最后一次检查中无松动的影像学证据。
对我们所收集资料的临床和影像学评估表明，全膝关节置换术能使患者长期恢复良好的下肢功能，有助于患者减少对周围环境的依赖。无论手术指征的初始诊断如何，上述情况似乎都会发生。
