CHANGES IN TIBIOFEMORAL KINEMATICS AND KINETICS DURING STAIR ASCENT AFTER PARTIAL MEDIAL MENISCECTOMY

摘要

Meniscectomy is a well-known risk factor for osteoarthritis (OA) in humans. Ft has been reported that total meniscectomy increases the risk of developing osteoarthritis radiographically by 14 times after 21 years and that partial meniscectomy increases the risk of developing radiographic evidence of osteoarthritis within 16 years by a factor of four. Two possible functional measures have been suggested as mechanisms for the development and progression of premature knee osteoarthritis: alterations in either kinematics or kinetics. Changes in kinematics, such as a shift in internal-external (IE) rotation after anterior cruciate ligament injury, have been suggested as a basis for an increased rate of cartilage thinning.
