A postal questionnaire was sent to 10,000 patients more than one year after their total knee replacement (TKR). They were assessed using the Oxford knee score and were asked whether they were satisfied, unsure or unsatisfied with their TKR. The response rate was 87.4% (8231 of 9417 eligible questionnaires) and a total of 81.8% (6625 of 8095) of patients were satisfied. Multivariable regression modelling showed that patients with higher scores relating to the pain and function elements of the Oxford knee score had a lower level of satisfaction (p < 0.001), and that ongoing pain was a stronger predictor of this. Female gender and a primary diagnosis of osteoarthritis were found to be predictors of lower levels of patient satisfaction. Differences in the rate of satisfaction were also observed in relation to age, the American Society of Anesthesiologists grade and the type of prosthesis. This study has provided data on the Oxford knee score and the expected levels of satisfaction at one year after TKR. The results should act as a benchmark of practice in the United Kingdom and provide a baseline for peer comparison between institutions.

:在他们的全膝关节置换术(TKR)一年多后,向10,000名患者发送了邮政问卷。使用牛津膝关节评分对他们进行评估,并询问他们是否对TKR感到满意,不确定或不满意。回应率为87.4%(9417份合格问卷中的8231份),总计81.8%(8095的6625份)患者满意。多变量回归模型显示,与牛津膝盖评分的疼痛和功能要素相关的评分较高的患者满意度较低(p <0.001),而持续疼痛是对此的更强预测指标。发现女性和骨关节炎的初步诊断是患者满意度降低的预测因素。满意度的差异还与年龄,美国麻醉医师学会等级和假体类型有关。这项研究提供了有关牛津膝关节评分和TKR一年后预期满意度的数据。结果应作为英国实践的基准,并为机构之间的同行比较提供基准。
