单髁置换术和全膝关节置换术的疗效比较的调查研究

Single Condylar Replacement and Compared the Curative Effect of total Knee Arthroplasty

目的比较单髁置换术和全膝关节置换术治疗单间室膝骨关节炎的临床疗效,以探讨合适的治疗方法。方法 100例单间室膝骨关节炎的患者分为观察组和对照组,对照组采用全膝关节置换术治疗,观察组采用单髁置换术治疗,比较两组的手术情况及术后疗效。结果观察组的手术时间、术中出血量、止血带时间、围手术期输血例数、术后3d血红蛋白下降水平和住院费用均显著少于对照组(P<0.05)。术后随访12~18个月,两组患者术后的疼痛、关节活动度、膝关节HSS评分、胫骨角方面均差异无统计学意义(P>0.05),均未出现感染、假体松动、关节翻修等并发症。观察组术后膝关节主动屈曲≥90°的时间显著短于对照组(P<0.05)。结论在严格掌握适应证的前提下,单髁置换术治疗单间室膝骨关节炎有疗效优势,且单髁置换术更具有微创手术的优点:创伤小,术后恢复快,关节功能恢复好,能保留本体感觉。

Objective To compare single condyle replacement and total knee replacement treatment of knee osteoarthritis clinical efficacy, single room to discuss appropriate treatment. Methods 100 patients with single chamber of knee osteoarthritis were divided into observation group and control group, control group treated with total knee replacement, the observation group USES single condyle replacement treatment, compared two groups of surgery and postoperative outcomes.Results Observation group of operation time, intraoperative blood loss, a tourniquet time cases, perioperative blood transfusion and postoperative hemoglobin level 3 d and hospitalization expenses were significantly less than control group(P<0.05).Postoperative follow-up of 12 to 18 months, two groups of patients with postoperative pain, knee joint HSS score, joint mobility, tibial Angle has no statistical significance(P>0.05), no infection occurred complications such as renovations and prosthesis loosening and joints. Observation group of postoperative knee joints active flexion of 90 ° or time was significantly shorter than the control group(P<0.05). Conclusion On the premise of strictly grasp the indications, single condyle replacement treatment knee osteoarthritis efficacy, single room but single condyle replacement has the advantages of minimally invasive surgery, trauma little, quicker recovery, good joint function recovery, can retain proprioception.
