The prognosis for improvement with conservative treatment is excellent if there is no functional instability requiring surgery. Surgical repairs for acute dislocation and chronic tears are also good. Casting for an acute dislocation has a success rate of only 50%. Therefore, this option should be reserved for patients with contraindications to surgery.

A study reviewed the long-term clinical and patient-reported outcomes of a cohort of patients with peroneal tendon tears treated with debridement and primary repair. The study of 18 patients with an average follow-up of 6.5 years found excellent long-term functional outcomes for patients with tears of the peroneal tendons treated with debridement and primary operative repair. The study also observed that the majority of patients returned to their previous level of activity without the need for reoperation or revision of the repair. [42]
