There is a paucity of information detailing functional outcome following total knee arthroplasty for this length of follow-up. We collected data from 187 knees in 150 surviving patients, beyond 15 years from implantation. Survival of the implant was confirmed and a patient administered questionnaire including WOMAC, SF-36 and patient satisfaction was used, data was scrutinised for differences between primary and revision knee surgery. Seventy knees were revised at a mean of 10.8 years. The mean WOMAC Pain score was 72 indicating predominantly mild pain. The mean WOMAC Function scores were lower at 55 indicating moderate limitation of most activities. No significant differences were found between revised and un-revised patients. Long-term pain and satisfaction scores in this population were good illustrating the benefits of TKA in the long term even in patients who have undergone revision surgery.
对于如此长时间的随访，关于全膝关节置换术后功能结果的详细信息匮乏。我们收集了150名存活患者187个膝关节的数据，这些数据来自植入后超过15年的患者。确认了植入物的存活率，并使用了一份患者问卷，其中包括WOMAC、SF - 36和患者满意度，对数据进行了仔细审查，以找出初次膝关节手术和翻修膝关节手术之间的差异。70个膝关节在平均10.8年时进行了翻修。WOMAC疼痛评分平均为72分，表明主要是轻度疼痛。WOMAC功能评分平均较低，为55分，表明大多数活动有中度受限。在翻修患者和未翻修患者之间未发现显著差异。该人群的长期疼痛和满意度评分良好，说明了全膝关节置换术在长期的益处，即使是在接受过翻修手术的患者中也是如此。
