Isokinetic Strength And Tone Of Knee Extensors Following Partial Meniscectomy: One-Year Study
XXVII FIMS: WORLD CONGRESS OF SPORTS MEDICINE(2002)
摘要
The recovery of knee extensor muscle isokinetic strength and tone in 15 male and 15 female patients aged 17-28 years during one-year period following partial meniscectomy was estimated in comparison with 30 age-and gender-matched healthy subjects as controls. lsokinetic peak torque (PT) of the knee extensors at angular velocities of 1.57, 3.14 and 4.71 rad/s and tone of rectus femoris (RF), vastus lateralis (VL) and vastus medialis (VM) muscles were recorded pre-operatively, 1, 3, 6 and 12 months post-operatively. The isokinetic PT deficit in the operated leg, which was the highest at 1.57 rad/s (41 and 43% for males and females, before the surgery, resp.) has been decreased 12 months after surgery (11% in both groups). The isokinetic PT deficit in the operated leg as compared with that in the non-operated leg was significant 1 month but not 3 months post-operatively. Recovery of the tone characteristics in the operated leg's VM muscle was more delayed than for VL and RF muscles during one-year following partial meniscectomy.
