膝关节高屈曲活动度对膝关节置换术患者生活质量的影响

目的：探讨膝关节高屈曲活动度对膝关节置换术患者生活质量的影响。方法选择2012年4月至2015年7月在我院骨一科进行膝关节置换手术的100例患者，以120°为界点将患者分为屈曲组(>120°)和对照组(<120°)各50例，比较两组患者术后3个月的膝关节HSS评分情况、术后12个月GQOLI评分，以及对术后屈曲能力的满意度。结果膝关节置换手术后3个月，两组患者在疼痛、功能、肌力方面比较差异均无统计学意义(P>0.05)，而在活动度和HSS总分方面比较差异均具有统计学意义(P<0.05)；两组患者术后12个月的GQOLI评分中，屈曲组在食欲、睡眠、日常生活、精神方面得分分别为(3.75±0.5)分、(3.37±0.21)分、(8.14±0.57)分、(4.51±0.21)分，明显优于对照组的(3.04±0.15)分、(4.28±0.27)分、(6.89±1.58)分、(3.27±0.22)分，差异均具有统计学意义(P<0.05)；屈曲组患者的并发症发生率为10%，明显低于对照组的20%，满意度为86%，明显高于对照组的56%，差异均具有统计学意义(P<0.05)。结论膝关节置换手术后可以较好的改变患者的关节活动度，提高满意度，并能改善患者的生活质量。

Effect of high knee flexion mobility on the quality of life of patients with knee arthroplasty

Objective To explore the effect of high knee flexion mobility on the quality of life of patients with knee arthroplasty. Methods From April 2012 to July 2015, A total of 100 patients who underwent knee replacement sur-gery in Department of Orthopedics of our hospital were divided into buckling group (>120° ) and control group (<120° ) with 120° for cut-off point, with 50 cases for each group. HSS score after 3 months of surgery, GQOLI score after 12 months and the satisfaction for the buckling capacity after surgery were compared between the two groups. Results After 3 months of knee replacement surgery, there were no significant differences between two groups in pain, function, and muscle force (P>0.05), while there were significant differences between two groups in activities degrees and total HSS (P<0.05). According to GQOLI score after 12 months, the scores of appetite, sleep, daily and spirit in buckling group (3.75 ± 0.5) points, (3.37 ± 0.21) points, (8.14 ± 0.57) points, (4.51 ± 0.21) points, respectively] were significantly better than control group (3.04±0.15) points, (4.28±0.27) points, (6.89±1.58) points, (3.27±0.22)] (P<0.05). The complications occurred rate in buckling group (10%) was significantly lower than control group (20%), P<0.05. The satisfaction de-grees in buckling group (86%) was obviously higher than control group (56%), P<0.05. Conclusion Knee joint replace-ment surgery can be preferable to change patient's joint motion, improve patient's satisfaction and quality of life.
