摘要: 目的 研发一种基于膝关节协会评分（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（TKA）术后患者的有效性。 方法 选取 10 名膝关节置换术后患者，利用 功能评估系统记录其术前、术后当天、术后第 4 天和术后 30 天的功能情况。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 将功能评估系统与临床医生评估进行比较，使用配对 T 检验方法对医生 凭借经验进行人工 KSS 评分的结果与系统评估的 KSS 评分结果进行分析，二者评分差异无统 计学意义(p < 0.326)，存在一致性。 结论 远程自助-互助式的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。
Objective To develop a remote self-mutual-aid functional assessment system based on the Knee Society Score (KSS), and to verify its effectiveness in home assessment of patients after total knee arthroplasty (TKA). Methods Ten postoperative knee replacement patients were selected and their functional status was recorded preoperatively, on the day of surgery, on postoperative day 4 and on postoperative day 30 using the functional assessment system. The system automatically calculates patient data including KSS score, total range of flexion, flexion contracture, extension lag, knee alignment, pain, and knee stability. Results The results of the functional assessment system were compared with those of the clinician evaluation.There was no statistical significance (p < 0.326) between the results of the manual KSS scoring by the doctor with experience and the KSS scoring by the system evaluation. Conclusion 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.
