全膝关节置换术后远程自助-互助式功能评估系统

目的 研发一种基于膝关节协会评分(knee society score, KSS)的远程自助-互助式功能评估系统,并验证其对膝关节置换(total knee arthroplasty,TKA)术后患者的有效性。 方法 选取 10 名接受 TKA 手术患者,利用功能评估系统记录其术前以及术后当天(0 d)、4 d 和 30 d 的功能情况。 系统自动计算患者的数据,包括 KSS 得分、屈曲总范围、屈曲挛缩、伸直迟滞、膝关节对线、疼痛和膝关节稳定性。 结果 比较医生凭借经验进行人工 KSS 评分结果与系统评估的 KSS 评分结果发现,二者评分差异无统计学意义,存在一致性。 结论 远程自助-互助式功能评估系统所采集的 KSS 分数与临床医生测评结果一致,该系统为 TKA 术后患者居家评估和远程术后康复指导提供了一种可靠、便捷的方法。

Remote Self-Mutual-Aid Functional Assessment System after Total Knee Arthroplasty

Objective To develop a remote self-mutual-aid functional assessment system based on the knee society score (KSS), and to verify its effectiveness for patients after total knee arthroplasty (TKA). Methods Ten TKA patients were selected, and their functional status was recorded preoperatively, on the day of surgery (0 d), on postoperative 4th and 30th day using the functional assessment system. The system automatically calculated the patient data including KSS score, total range of flexion, flexion contracture, extension lag, knee alignment, pain, and knee stability. Results The results of manual KSS scores by physicians based on experience were compared with the result of KSS scores assessed by the system, and there was no statistically significant difference between the scores, indicating an agreement. Conclusions The KSS scores collected by the remote self-mutual-aid functional assessment system are consistent with the results assessed by clinicians, and the system provides a reliable and convenient method for home assessment and remote rehabilitation guidance for patients after TKA.
