Quantification with gait analysis of biomechanic risk protofactors regarding the patellar tendinosis in athletes with varus knee
A prospective study of gait and patellar tendinosis in 11 athletes with varus knee was reported. The objectives are monitoring with gait analysis of the homogeneous distribution of the articular loadings in athletes with varus knee with the aim of rehabilitation.
The comparison of the articular moments during the loading phase of the athletes with varus knee compared with the control group, quantify the energy employed in friction on the level of the patellar tendon. This is conditioned by a more or less correct periarticular muscular activation with an influence on the beginning of the tendinosis. A vicious cycle may occur with continuing eccentring stress on patellar tendon associated with varus axial alignment.
The identification and the quantification of such abnormalities are essential not only to prevent femur-patellar overloads, but also to optimize the rehabilitation treatment. Dynamic measurements obtained with gait analysis have predictive value.
