Despite the success of total knee arthroplasty (TKA) in treating end-stage knee arthritis, 11% to 19% of patients are dissatisfied with the outcome of their surgery. In this study we investigated how satisfied overall patients are with the outcome of posterior stabilized TKA and what particular functional deficits or residual symptoms cause the most dissatisfaction for patients after surgery.
Using patient-completed validated questionnaires, we retrospectively analyzed data for 1013 posterior-stabilized TKAs performed in 748 Chinese patients regarding the overall satisfaction with surgery and the importance ranking of each of 15 specific functions and residual symptoms.
Our data demonstrate an overall satisfaction rate of 87.4%. Satisfaction percentages ranged from 45.0% to 89.0%. The top 6 dissatisfactory items were sitting with legs crossed (dissatisfaction rate of 55.0%), squatting (51.7%), walking fast or jogging (45.4%), knee clunking (34.5%), abnormal feeling in knee (31.2%), and climbing stairs (28.2%). The top 6 important functions or issues were pain relief, walking on flat ground, climbing stairs, ability to return to household work, decreased limping, and squatting.
Approximately 1 in 8 patients was dissatisfied with overall outcome. Patients were most dissatisfied with climbing stairs and squatting, functions that they considered most important.
尽管全膝关节置换术（TKA）在治疗终末期膝关节炎方面取得了成功，但仍有11%至19%的患者对手术结果不满意。在本研究中，我们调查了患者对后稳定型TKA手术结果的总体满意度，以及哪些特定的功能缺陷或残留症状导致患者术后最不满意。
我们使用患者填写的经过验证的问卷，回顾性分析了748例中国患者进行的1013例后稳定型TKA手术的数据，内容包括对手术的总体满意度以及15项特定功能和残留症状各自的重要性排名。
我们的数据显示总体满意度为87.4%。满意度百分比范围为45.0%至89.0%。最不满意的6项是盘腿坐（不满意率为55.0%）、下蹲（51.7%）、快走或慢跑（45.4%）、膝关节弹响（34.5%）、膝关节异常感觉（31.2%）和爬楼梯（28.2%）。最重要的6项功能或问题是疼痛缓解、平地行走、爬楼梯、恢复家务劳动的能力、跛行减轻和下蹲。
约八分之一的患者对总体结果不满意。患者对爬楼梯和下蹲最不满意，而他们认为这些功能是最重要的。
