EFFECTS OF BODY WEIGHT MODIFICATION ON INTERNAL KNEE CONTACT FORCES DURING GAIT

摘要

Obesity is commonly considered a risk factor for the development of knee osteoarthritis . Previous studies have shown that reductions in body weight correspond to reductions in total knee joint compressive forces (as calculated by inverse dynamics). A recent study showed that external knee load measurements are not strong predictors of internal knee contact forces. Therefore, direct measurement of knee contact force is important for understanding how body weight changes impact knee joint loading. Force-measuring knee implants can directly measure internal knee contact forces.
