目的 探讨运动疗法在改善膝关节骨性关节炎患者运动功能及疼痛程度中的作用。方法 选取2021年9月—2023年12月收治的膝关节骨性关节炎患者66例,采用随机数字表法将其分为两组,即常规干预的对照组和对照组基础上实施运动疗法的观察组,每组各33例。比较两组患者膝关节运动功能,疼痛程度、生活质量及膝关节活动性。结果 干预后,观察组Lysholm膝关节功能评分法（LKSS）评分高于对照组（P<0.05）;观察组无痛人数占比高于对照组,中度疼痛人数占比则低于对照组（P<0.05）;观察组生活质量综合评定问卷中的躯体功能、心理活动、社会能力、物质生活状态各项评分均高于对照组（P<0.05）;两组屈膝间隙比较,差异无统计学意义（P>0.05）,但观察组伸膝间隙大于对照组（P<0.05）,且主动屈膝90°、120°的时间均短于对照组（P<0.05）。结论 运动疗法可改善膝关节骨性关节炎患者的运动功能,缓解疼痛程度,提升生活质量,值得推广。

Objective To explore the role of exercise therapy in improving motor function and relieving pain level in patients with knee osteoarthritis. Methods From September 2021 to December 2023, 66 patients with knee osteoarthritis were randomly divided into two groups by random number table method： a control group receiving routine intervention and an observation group receiving exercise therapy, with 33 patients in each group. Motor function, pain level, quality of life, and knee mobility were compared between the two groups. Results After designed intervention, the Lysholm knee scoring scale （LKSS） score in the observation group was higher than that in the control group （P<0.05）. The proportion of painless patients in the observation group was higher than that in the control group, while the proportion of moderate pain paients was lower （P<0.05）. The physical function, psychological activity, social ability, and material life state scores of Generic Quality of Life Inventory in the observation group were higher than those of the control group （P<0.05）. No significant difference was found in flexion gap between the two groups （P>0.05）, but the observation group showed larger extension gap and shorter time for active knee flexion at 90° and 120° than the control group （P<0.05）. Conclusion Exercise therapy can improve motor function, alleviate pain, and enhance quality of life of patients with knee osteoarthritis, and it is worth promoting.
