What Is It?
Peroneal tendinitis, or tendinopathy can occur suddenly or be a chronic issue. The peroneal tendons are located on the outside of the lower leg along the tibia (shin bone) and insert into the bottom of the foot. Peroneal tendinitis often occurs in runners, dancers, and basketball players – sports that require repetitive motion, jumping, and frequent changes in direction. Factors that contribute to peroneal tendinitis include chronic inversion ankle sprains, tight calf muscles, poor biomechanics of the foot, and training errors. Like other tendinopathies of the lower leg, peroneal tendonitis responds well to progressive strengthening, flexibility exercises, and improving foot & ankle biomechanics.
