不同内固定方法对髌骨骨折术后膝关节功能恢复的影响

Effects of different internal fixation methods on functional recovery of knee joint after operation of patellar fracture

目的:分析3种内固定方法对髌骨骨折术后膝关节功能康复的影响。方法:对收治的髌骨分离骨折手术患者分为钢丝环扎组、钢丝张力带组及可吸收线张力带组。每组各30例,进行术后早期规范的膝关节功能康复训练,并对术后2,3,6个月的膝关节功能恢复情况做出对比评定的前瞻性研究。结果:术后两三个月的膝关节活动度(ROM)比较,钢丝张力带组、可吸收线张力带组明显优于钢丝环扎组;术后6个月膝关节功能远期评定可吸收线张力带组优于钢丝张力带组及钢丝环扎组。结论:钢丝张力带、吸收线张力带组由于内固定稳固,术后可早期的膝关节持续被动运动,更符合现代骨科功能康复的治疗理念,吸收线张力带组在术后被动运动训练时无膝关节皮肤异物刺激感,故膝关节功能康复效果更佳。

AIM:To analyze the effects of three internal fixation methods for patellar fracture on functional recovery of knee joints. METHODS:The hospitalized patients with patellar fracture were divided into 3 groups:group A(treated with cerclage with steel wire),group B(treated with steel wire tension band) and group C(treated with absorbable line tension band),with 30 patients in each group.Knee rehabilitation training specified earlier was performed after operation.The prospective study on functional recovery of knee joint was evaluated and compared 2,3 and 6 months after operation. RESULTS:The range of motion(ROM) of knee joint in group B and C was wider than that in group A.The long term assessment of knee joint function 6 months after operation was better in group C than in group A and B. CONCLUSION:Persistent passive movement in an early stage is found because better stability after internal fixation with cerclage with steel wire and steel wire tension band,which accords with treatment concept of orthopaedic functional rehabilitation closely.There is no foreign body sensation of the skin of knee joint after internal fixation with absorbable line tension band when passive motion is performed,so it is better for functional rehabilitation of knee joint.
