Tendon tear problems, sprains and strains of the foot occur in a number of different regions through the foot and ankle. Achilles tendon injuries are probably the most common of these, but peroneal tendon strains and sprains can also be quite common. The peroneal runs down through the outside and around the bottom of the ankle and is an important stabiliser to the foot. Also posterior tibial tendinopathy. Accurate diagnosis is essential.
