摘要
目的:通过对将行单侧全膝关节置换术(TKR)的骨性关节炎(OA)患者患侧、健侧膝关节肌力及同年龄组健康者膝关节肌力的测试研究,找出三者的关系,为围手术期膝关节功能康复提出指导意见。方法:以18例准备进行单侧TKR的患者为观察组进行健侧、患侧膝关节等速向心肌力测试,以峰力矩(PT)、峰力矩/体重(PT/BW)、单次最大做功和屈/伸肌肌力比值(H/Q)为观察指标,并以15例健康者为对照组进行相同测试。结果:在低速(60°/S)和高速(180°/S)测试中,观察组患侧膝关节伸肌峰力矩(PT)、峰力矩体重比(PT/BW)、单次最大做功均较健侧显著下降(P<0.05),患侧膝关节屈肌各观察指标中除单次最大做功在高速测试中较健侧显著下降(P<0.05)外,其余指标均与健侧比较没有显著性差异(P>0.05);健侧膝关节除H/Q比值在低速测试时没有显著性差异外(P>0.05),其余各观察指标均较对照组膝关节有显著下降(P<0.01)。结论:患者健、患侧膝关节肌肉功能均比健康人差,患侧膝关节肌肉功能的下降以伸肌最为显著,提示TKR患者围手术期功能训练患侧应以伸肌训练为主,同时兼顾健侧肢体屈伸肌训练。
Objective： To evaluate the functional changes in the concentric muscle strength of the knee extensors and flexors in patients with unilateral knee osteoarthritis before total knee replacement （TKR）. Method： A Biodex System3 isokinetic test system was used to assess the concentric muscle strength of the knee extensors and flexors of the involved and uninvolved limbs in 18 patients suffering from osteoarthritis;knees of 15 healthy persons were tested also. The peak torque （PT）, peak torque/body weight （PT/BW）, maximal repetition of total work （MRTW）, hamstrings/quadriceps （H/Q） were recorded. Result： At the low angular velocity （60°/s） and high angular velocity （180°/s）test program, the PT,PT/BW,MRTW of the knee extensors of the involved limbs were significantly less than that of the uninvolved legs （P〈0.05）. The records of the knee flexors of the involved limbs were not significantly less than that of the uninvolved legs （P〉0.05） except The MRTW in high angular velocity（180°/s） test program（P〈 0.05）; the records of the uninvolved legs were significantly less than that of the healthy legs （P〈0.01） except the H/Q ratio at low angular velocity test program （P〉0.05）. Conclusion： The muscle strength of the knee OA patients before TKR was less than heahhy persons, the most significant reduce was the extensors of the involved knee.
