Peroneal tendon injuries can lead to pain over the outside (lateral) aspect of the ankle. These injuries can involve swelling and inflammation of the tendons, referred to as tendonitis. Tendonitis is often treated with anti-inflammatory medicines, bracing, therapy, or injections. If these measures do not work, arthroscopic or open tendon debridement is performed. More severe injuries include tears of one or both tendons and dislocation of the tendons. Conservative measures are also employed at first in most cases, but if these fail surgical repair is indicated.
