膝骨关节炎患者本体感觉特征

目的 探讨行单髁膝关节置换术(unicondylar knee arthroplasty，UKA) 和全膝关节置换术(total knee arthroplasty，TKA)膝骨关节炎( knee osteoarthritis，KOA)患者术前膝关节本体感觉特征。方法 选取单间室KOA患者29名，15例接受 UKA 治疗（UKA组），14例接受 TKA 治疗（TKA组）。术前1~3 d进行测试，对比UKA、TKA组KOA患者膝关节学会评分（knee society score, KSS）以及手术组与健康对照组的位置觉和运动觉特征。结果 UKA、TKA组之间KSS评分有显著差异，位置觉和运动觉无显著差异；UKA、TKA组患者术侧腿和未术侧腿之间位置觉和运动觉均无显著差异，对照组左、右腿位置觉和运动觉无显著差异；与对照组相比，UKA、TKA组在60°位置觉时术侧腿和未术侧腿均有显著差异，患者术侧腿和未术侧腿的运动觉也均有显著差异。结论 与健康对照组相比，KOA患者术前的膝关节本体感觉明显减退，但UKA、TKA组患者术前本体感觉特征相近。

Characteristics of Proprioception in Patients with Knee Osteoarthritis

Objective To explore the proprioception characteristics of knee joints for knee osteoarthritis (KOA) patients before unicondylar knee arthroplasty (UKA) and total knee arthroplasty (TKA). Methods Twenty-nine single-compartment KOA patients were selected. Fifteen patients were treated with UKA (UKA group) and fourteen patients were treated with TKA (TKA group). The test was performed 1 to 3 days before the operation.The keen society scores (KSS) of KOA patients in UKA group and TKA group were compared, and their joint position sense and kinesthesia were compared with control group. Results Significant differences in KSS were found in TKA group and UKA group, and the knee joint position sense and kinesthesia showed no significant differences between TKA group and UKA group.There were no significant differences in the knee joint position sense and kinesthesia between the operated leg and unoperated leg in TKA group and UKA group, and between the left leg and right leg in control group. Compared with control group, there were significant differences between UKA group and TKA group in 60° position sense of the operated leg and unoperated leg.The kinesthesia of the operated leg and unoperated leg in UKA group and TKA group were also significantly different from that in control group. Conclusions Compared with control group, the proprioception of the knee joint in KOA patients was significantly reduced before the surgery, but the characteristics of proprioception in UKA group and TKA group were similar.
