These are related to the normal physiology of locomotion where the strongest pressures are often imposed on the medial sides of the joints (fetlock, carpus, hock, stifle...). All limb deviation defects such as valgus (outward deviation) or varus (inward deviation) will aggravate the condition. These asymmetries lead to a concentration of joint or tendon biomechanical stresses on one side of affected limbs. If they are not corrected, they can cause cartilage, bone or ligament lesions that result in lameness. The aim is to rebalance the loads in order to relieve the lesions using an appropriate kinetherapeutic shoe.
