目的：探究膝关节单髁置换术(UKA)与全膝关节置换术(TKA)治疗膝关节内侧单间室骨性关节炎的临床治疗效果。方法：将 2011 年4月-2015 年7 月期间因膝关节单间室骨性关节炎入院接受治疗的89 例患者纳入本研究，随机分为研究组和对照组，研究组44 例，行UKA 手术，对照组45例，采用TKA 手术方式治疗。对两组患者进行术后随访，对比临床治疗效果。结果：两组术前均有明显膝关节疼痛，术后膝关节疼痛均明显改善，组间差别无显著统计学意义(X2=1.323，P=0.250>0.05)；术后膝关节屈曲角度、 HSS 评分相对于术前均显著改善，研究组术后膝关节屈曲角度（111.2± 18.8）度高于对照组的（98.6± 14.7）度，差异有统计学意义 (P<0.05)；HSS 评分（87.6± 13.7）分高于对照组的(73.2± 16.8)分，差异有统计学意义(P<0.05)；研究组膝关节屈曲至90 度时间比对照组短，数据差异有统计学差异(t=-2.303，P=0.024<0.05)。结论：膝关节内侧单间室骨性关节炎采用UKA与TKA均能取得一定临床效果，减轻患者痛苦，改善膝关节功能，但UKA 临床疗效较好，手术创伤较小，术后恢复较快。

英文摘要:

Objective:To explore the clinical effects of unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA) in the treatment of medial compartment osteoarthritis of the knee joint.Methods:A total of 89 patients with medial compartment osteoarthritis of the knee joint, who were treated in Weifang Hospital of Traditional Chinese Medicine of Shandong Province from April 2011 to July 2015, were selected and randomly divided into research group (n=44) and control group (n=45). The research group was given UKA, while the control group, TKA. The patients of the two groups were followed up, and the clinical effects were compared.Results:The two groups of patients had obviously knee pain before operation and were significantly improved after operation, there was no significance in the difference between the two groups (X2=1.323, P=0.250>0.05). The knee flexion angle of research group was (111.2± 18.8) degrees, which was higher than that(98.6± 14.7) of control group, the difference was statistically significant(P<0.05). The HSS score of research group was (87.6± 13.7), which was higher than that(73.2± 16.8) of control group, the difference was statistically significant (P<0.05). The time of knee flexion to 90 degrees of research group was shorter than that of control group, the difference was statistically significant (t=-2.303, P=0.024<0.05).Conclusion:UKA and TKA can obtain a certain clinical effect in the treatment of patients with medial compartment osteoarthritis of the knee joint, reduce the pain of patients, and improve knee joint function, but the clinical effect of UKA is better, with less surgical trauma and faster postoperative recovery.
