膝关节置换在膝关节内翻畸形中的应用研究

Clinical research of total knee arthroplasty for patients with knee of varus deformity

目的探讨膝关节置换在膝关节内翻畸形中治疗应用。方法选择该院收入的膝关节内翻畸形的患者共56例,患者给予全膝关节置换术治疗,观察患者术后膝关节屈曲挛缩度、HSS评分、膝关节内翻角、关节活动度及并发症发生情况。结果本组患者获6～24个月的随访,平均10.8个月。患者术后膝关节屈曲挛缩度、HSS评分、膝关节内翻角及关节活动度与术前比较,差异有统计学意义(P<0.05),本组患者中1例术后1个月发生下肢深静脉血栓,经行保守治疗后痊愈,1例患者术后半年发生了迟发性的感染,给予术后翻修处理。结论人工全膝关节置换治疗膝关节内翻畸形疗效显著,术中软组织平衡、准确的切骨是治疗膝关节内翻畸形的关键。

Objective To discuss the application of total knee arthroplasty for patients with knee of varus deformity.Methods 56 knee of arus deformity patients were selected in our hospital,patients with total knee arthroplasty,to observation patients postoperative flexion contracture degree、HSS score、knee turn inward angle、joint mobility and complications.Results All patients with 6~24 months of follow-up,an average of 10.8 months.Patients postoperative flexion contracture degree、HSS score、knee turn inward angle、joint mobility postoperative has statistical different with preoperative(P<0.05).Our groups patients 1 cases occurrence lower limb deep vein thrombosis after one month,1 patients happened late-occurred infection after six months,given postoperative overhaul processing.Conclusion TKA patients with the knees of varus deformity contracture can have an excellent clinic result.The keys of operation are proper balancing of the soft tissues and accurate bone cutting.
