Joint load considerations in total knee replacement.
Estimates of knee joint loadings were calculated for 12 normal subjects from kinematic and kinetic measures obtained during both level and downhill walking. The maximum tibiofemoral compressive force reached an average load of 3.9 times body-weight (BW) for level walking and 8 times BW for downhill walking, in each instance during the early stance phase. Muscle forces contributed 80% of the max...
متن کاملKnee Power Is an Important Parameter in Understanding Medial Knee Joint Load in Knee Osteoarthritis
OBJECTIVE To determine the extent to which knee extensor strength and power explain variance in knee adduction moment (KAM) peak and impulse in clinical knee osteoarthritis (OA). METHODS Fifty-three adults (mean ± SD age 61.6 ± 6.3 years, 11 men) with clinical knee OA participated. The KAM waveform was calculated from motion and force data and ensemble averaged from 5 walking trials. The KAM ...
متن کاملCumulative Knee Adductor Load and Clinical Measures in Knee Osteoarthritis
INTRODUCTION Knee osteoarthritis (OA) is a multi-factorial degenerative joint disaese resulting in pain and altered neuromuscular performance. Repetition and abnormal loading, combined with mechanical factors are attributed to the progression of knee OA [1,2], but the effects of repetitive weight bearing activity remain unclear. The cumulative knee adductor load (CKAL) is a parameter that repre...

متن کاملKnee joint muscles neuromuscular activity during load-carrying walking.
OBJECTIVE To investigate the effects of increasing load on changes in the muscle activity ratio and onset of vastus medialis (VM), vastus lateralis (VL) and biceps femoris (BF) during load-carrying walking. MATERIALS AND METHODS Sixteen strength-trained men performed an isometric test for knee flexion/extension using a dynamometer followed by walking with progressively increasing loads of up ...
