Lateral dislocations and patellar instability are injuries that mainly involve younger people: a targeted rehabilitation program with specific exercises is essential to recover strength, stability, dynamism and performance of the lower limb and to ensure the return to an optimal physical condition. It is important to concentrate the training on those muscles that provide most stability, both statically and dynamically, to the lower limb, pelvis and trunk: namely, the gluteus medius and the core muscles.
