Efficacy and patient function of unilateral condylar knee replacement in treatment of spontaneous late osteonecrosis of knee joint in youth

目的探讨膝关节单髁置换术在青年晚期膝关节自发性骨坏死治疗中的临床疗效以及对患者功能恢复的效果。方法在本院2014年3月至2016年3月收治的青年晚期膝关节自发性骨坏死患者中,选择具有可比性的20例患者作为研究对象,给予膝关节单髁置换术治疗,分别对比治疗前后的膝关节功能、疼痛程度、关节活动度以及并发症发生情况。结果治疗前后患者的膝关节功能存在明显的差异,治疗后患者的膝关节功能比治疗前明显减轻(P<0.05);治疗前后患者的疼痛程度存在明显的差异,治疗后患者的疼痛程度明显好于对照组患者的疼痛程度(P<0.05);治疗前后患者的关节活动度差异不明显(P>0.05);20例患者术后切口均愈合,未出现严重的并发症。结论膝关节单髁置换术在青年晚期膝关节自发性骨坏死治疗中的应用效果显著,患者术后功能恢复良好,值得临床推广及应用。

Objective To investigate the clinical effect of unicondylar arthroplasty in the treatment of spontaneous osteoneerosis of knee joint in young patients and the effect of functional recovery. Methods From March 2014 to March 2016, 20 patients with spontaneous osteonecrosis of the knee joint were treated with unicondylar arthroplasty. The results were compared with those of the control group knee function before and after treatment, the degree of pain, joint mobility and complications occurred. Results Before and after treatment, the knee function of the patients was significantly different, after treatment, the knee function of patients was significantly better than before treatment of patients with knee function ; before and after the pain in patients with significant differences in the degree of pain after treatment Which was better than that of the control group.
