全膝关节置换术与单髁置换术治疗膝内侧骨关节炎的效果对比

Comparison of the effect of total knee replacement and single condyle replacement in the treatment of medial knee osteoarthritis

目的 :比较使用全膝关节置换术(TKA)与单髁置换术(UKA)治疗膝内侧骨关节炎的效果。方法 :将2017年7月至2018年7月期间三台县人民医院收治的70例膝内侧骨关节炎患者随机分为对照组和观察组。为对照组患者使用TKA进行治疗治疗。为观察组患者使用UKA进行治疗。然后观察比较两组患者进行步态活动时膝关节活动的角度及胫骨移位的情况。结果 :治疗后,观察组患者进行步态活动时膝关节外翻的角度、外旋的角度及屈曲的角度均大于对照组患者,其胫骨向前移位的距离及向后移位的距离均小于对照组患者,其胫骨向上移位的距离及向内移位的距离均大于对照组患者,P <0.05。结论 :与使用TKA相比,使用UKA治疗膝内侧骨关节炎有利于保持患者进行步态活动时膝关节正常的活动角度,减小其胫骨向前及向后移位的距离。

Objective:To compare the effects of total knee replacement(TKA)and single condylar replacement(UKA)in the treatment of medial knee osteoarthritis.Methods:70 patients with medial knee osteoarthritis admitted to santai county people’s hospital from July 2017 to July 2018 were randomly divided into control group and observation group.Patients in the control group were treated with TKA.Patients in the observation group were treated with UKA.Then the Angle of knee joint motion and tibial displacement were observed and compared between the two groups.Results:after treatment,the observation group of patients during gait activity knee valgus Angle,rotation Angle and buckling Angle were greater than the control group of patients,the tibia forward shift distance and backward shift distance is less than the control group of patients,the tibial upward shift distance and the distance from inward shift were greater than the control group patients,P<0.05).Conclusions:compared with TKA,UKA therapy for medial knee osteoarthritis is beneficial in maintaining the normal Angle of knee motion during gait and reducing the distance of tibia forward and backward displacement.
