OBJECTIVES The aim of this study was to explore the contribution of biomechanical factors to the development and progression of knee osteoarthritis (OA) by investigating whether the offspring of subjects with medial tibiomfemoral OA demonstrate gait abnormalities in the absence of OA. METHODS Three-dimensional gait analyses were performed on 9 offspring of people with medial tibiofemoral OA a...

To provide a scientific basis for the design of bicycle pedals which possibly alleviate over-use knee injuries, two hypotheses were tested in the present study. The two hypotheses were: (1) that the three-dimensional pedal constraint loads; and (2) that the three-dimensional intersegmental knee loads would be reduced more significantly by a foot/pedal platform allowing both adduction/abduction ...

This study investigated asymmetry between lower extremities during the landing and takeoff phases of a vertical drop jump (VDJ) in adolescent athletes following anterior cruciate ligament reconstruction (ACLR) examined if performance was affected by reducing height. Thirty-three who underwent ACLR were referred for 3D biomechanical assessment before returning to play (mean age 15.9, SD 1.3 year...

Stair gait is a useful activity for the assessment of knee function. The aim of this study was to determine whether knee joint kinematics and moments are affected by the choice of stair gait cycle (SGC) and the step used to measure ground reaction forces (GRFs). This was investigated through motion analysis of ten non-pathological subjects as they ascended and descended a four-step staircase. T...

Osteoarthritis of the knee is a debilitating condition affecting increasing numbers of individuals each year. One option for treatment is orthotic knee braces, but a little independent reviews have taken place to date on their relative outcomes for users. This study therefore evaluates the efficacy of different types of knee orthoses (braces) with regard to key aspects of use, including gait pa...

Knee osteoarthritis (OA) is a major cause of knee pain, leading to physical dysfunction. External adduction moment (KAM), surrogate measure contact force (KCF) in the medial compartment, related but association between KCF and pain severity remains unclear. This study aimed reveal differences due severity. Twenty-eight patients with OA were evaluated symptoms including via Society Score. Based ...
