Knee kinematics and hip abductor strength in knee injury
A randomised trial into the effect of an isolated hip abductor strengthening programme and a functional motor control programme on knee kinematics and hip muscle strength.
Side lying hip abduction with ankle weights was performed until failure; completing 3 unsupervised sets every other day. The FMC exercise was done by gradually progressing from double leg to single leg squatting. The desired alignment for up to 25 daily repetitions providing alignment could be maintained.
No statistically significant differences in knee kinematics following 5 weeks of an isolated hip abductor strengthening program or a FMC exercise program were found. A tendency towards clinically significant improvements in reduction of dynamic knee valgus and internal rotation was observed. Both groups demonstrated significant and similar gains in strength of the hip abductors. It is possible that such approaches could lead to a reduction of knee valgus and internal rotation and subsequent reduction in knee pain risk.
