全膝关节置换术后肌力训练对膝关节功能的影响

目的探讨肌力训练对全膝关节置换术后患膝关节功能恢复的影响。方法选取96例全膝关节置换患者，将其随机分为观察组及对照组。对照组患者术后给予常规康复训练；观察组患者在此治疗基础上，重点进行股四头肌及胭绳肌肌力训练。治疗2周后分别对2组患者的膝关节活动度、疼痛、股四头肌和胭绳肌肌力进行评定，并采用美国膝关节外科学会膝关节评分法（KSS）、美国特种外科医院（HSS）膝关节百分评分系统对患膝功能进行评定。结果2组患者经治疗后，其膝关节活动度及疼痛方面组间差异均无统计学意义（P〉0．05），但股四头肌、胭绳肌肌力及KSS、HSS总分组间差异均有统计学意义（P〈0．01）。结论肌力训练对全膝关节置换患者膝关节功能的恢复具有显著促进作用，可有效增强患膝关节的稳定性，改善患肢功能，提高生活质量。

The effects of muscle strengthening for the knee functioning after total knee replacement(TKR)

Objective To investigate the effects of muscle strengthening on the knee function after total knee replacement (TKR). Methods Ninety-six patients with TKR divided into two groups. One group of the patients was treated with routine rehabilitation therapy, and another with intensive strengthening of quadriceps femoris and hamstring in addition to the routine rehabilitation therapy. After two weeks, all of the patients were evaluated with regard to the range of knee motion, pain, strength of quadriceps femoris and hamstring, and KSS, HSS score. Results It was showed that there was no significant difference between the two groups in terms of the ROM and pain (P>0. 05). However, muscles strength and KSS, HSS score were significantly different between the two groups (P<0.01). Conclusion Muscle strengthening exercises is of special importance for the function of TKR, it can enhance the stability of knee joint, improve the function of the affected limb and the patient's quality of life.
