绞链式与非绞链式人工全膝关节置换术治疗股骨下端恶性骨肿瘤患者的临床效果比较

目的比较绞链式与非绞链式人工全膝关节置换术治疗股骨下端恶性骨肿瘤患者的临床效果。方法依据治疗方式将95例股骨下端恶性骨肿瘤患者分为观察组(n=50)和对照组(n=45),对照组患者接受非绞链式人工全膝关节置换术治疗,观察组患者接受绞链式人工全膝关节置换术治疗。比较两组患者的临床疗效、膝关节功能和并发症发生情况。结果治疗后,观察组患者的临床总有效率为92.00%,明显高于对照组的71.11%,差异有统计学意义(P﹤0.01)。观察组患者Neer评分优良率为90.00%,明显高于对照组患者的64.44%,差异有统计学意义(P﹤0.01)。观察组患者术后异化骨位、感染、坏死及脱位发生率均低于对照组患者,差异均有统计学意义(P﹤0.05)。结论绞链式人工全膝关节置换术可提高股骨下端恶性骨肿瘤患者的临床疗效,明显降低术后感染、坏死等并发症发生率,促进患者的肢体功能恢复。

Comparison of the clinical effects of hinged and non-hinged artificial total knee arthroplasty in the treatment of patients with malignant bone tumor of the terminal femur

Objective To compare the clinical effects of hinged and non-hinged artificial total knee arthroplasty in the treatment of patients with malignant bone tumor of the terminal femur.Method According to the treatment,95 patients with malignant bone tumor of the terminal femur were divided into observation group(n=50,treated with hinged artificial total knee arthroplasty)and control group(n=45,treated with non-hinged artificial total knee arthroplasty).The clinical efficacy,knee function and complications in two groups were compared.Result After treatment,the clinical total efficiency of the observation group was 92.00%,which was significantly higher than 71.11%of the control group,and the difference was statistically significant(P<0.01).The Neer rating excellent rate of Neer score in the observation group was 90.00%,which was significantly higher than 64.44%of the control group,and the difference was statistically significant(P<0.01).The incidence of postoperative heterotopic ossification,infection,necrosis and dislocation in the observation group were lower than those in the control group(P<0.05).Conclusion The hinged artificial total knee arthroplasty can improve the clinical efficacy of patients with malignant bone tumors of the terminal femur,significantly reduce the incidences of postoperative infection,necrosis and other complications,and improve the recovery of limb function.
