Achilles and peroneal tendon injuries in the athlete. An expert's perspective

Peroneal tendonopathy or injuries are not common but may be troubling to the sports enthusiast. Prompt diagnosis and treatment usually result in complete recovery with conservative measures. Biodynamic orthosis with deep heel cups and a long lateral flange extension often are required for return to activity. MR imaging is helpful in difficult, persistent cases to check for ruptures. Surgery is not commonly performed but if required is usually successful in correcting the pathology. Alternative medicine may improve treatment outcomes. Biomechanical functional analysis and attention to training errors is essential in any lower extremity injury or pathology.
