The aim of this study was to explore the curative effect of knee arthroplasty on patients with osteoarthritis and analysis of their long-term joint function.
Ninety-six cases of osteoarthritis patients, collected in our hospital from June 2010 to May 2011, were divided into control group and observation group (N.=48 in each group). Patients in observation group were treated by knee replacement, and patients in control group were treated by arthroscopic debridement. Bleeding during operation of patients and the operation time in both groups were comparable during their followed up for 6~60 months, with an average of 52 months. Neer score was used to compare the curative effect of patients after 6 months; knee society score (KSS) was used to compare knee joint function and knee joint of motion (ROM) of patients several days prior to surgery and after 6 months, 12 months, 24 months, and 48 months. Visual analogue scale (VAS) was used to compare pain degrees of patients at the last follow-up.
By Neer score comparison, after 6 months excellent and good rate of patients in observation group (91.67%) was obviously higher than that of control group 70.83% (P<0.05); ROM of patients in observation group was obviously higher than that in control group (P<0.05); After six months, KSS score of patients in both groups greatly improved. As well, with the extension of time, their knee joint function showed a better trend, and KSS score of patients in observation group was obviously higher than that of control group (P<0.05). Pain of patients in observation group was significantly lower than that in control group (P<0.05).
Both arthroscopy debridement and knee replacement have good curative effect. The curative effect of knee replacement was better, postoperative knee joint activity was obviously improved, the long-term recovery of knee joint function was good, and knee replacement can reduce the pain of the patients.
本研究旨在探讨膝关节置换术对骨关节炎患者的疗效及其长期关节功能分析。
选取2010年6月至2011年5月我院收治的96例骨关节炎患者，分为对照组和观察组（每组48例）。观察组患者行膝关节置换术，对照组患者行关节镜清理术。两组患者手术中的出血量和手术时间在随访6至60个月（平均52个月）期间具有可比性。采用Neer评分比较患者术后6个月的疗效；采用膝关节协会评分（KSS）比较患者术前及术后6个月、12个月、24个月和48个月的膝关节功能及膝关节活动度（ROM）。采用视觉模拟评分法（VAS）比较患者末次随访时的疼痛程度。
通过Neer评分比较，观察组患者术后6个月的优良率（91.67%）明显高于对照组（70.83%，P<0.05）；观察组患者的ROM明显高于对照组（P<0.05）；术后6个月，两组患者的KSS评分均显著提高。此外，随着时间的延长，两组患者的膝关节功能均呈更好的趋势，且观察组患者的KSS评分明显高于对照组（P<0.05）。观察组患者的疼痛明显低于对照组（P<0.05）。
关节镜清理术和膝关节置换术均有良好疗效。膝关节置换术的疗效更好，术后膝关节活动明显改善，膝关节功能长期恢复良好，且膝关节置换术可减轻患者疼痛。
