Anterior ankle impingement is a frequent cause of disability in athletes.1 This condition results from repetitive trauma over time, which leads to osseous and soft-tissue impingement, pain, and decreased ankle range of motion (ROM).
First termed footballer’s ankle, this condition is linked to repeated, forceful plantarflexion,2 though later studies attributed the phenomenon to repeated dorsiflexion resulting in periosteal hemorrhage.3 Both osseous and soft-tissue structures can cause impingement at the tibiotalar joint, often with osteophytes anteromedially at the tibial talar joint. Soft-tissue structures, including hypertrophic synovium, meniscoid lesions, and a thickened anterior talofibular ligament, more often cause anterolateral impingement.4-6 This process results in pain in extreme dorsiflexion, which comes into play in almost all football maneuvers, including sprinting, back-peddling, and offensive and defensive stances. Therefore, maintenance of pain-free dorsiflexion is required for high-level football. Decreased ROM can lead to decreased ability to perform these high-level athletic functions and can limit performance.
Arthroscopic débridement improves functional outcomes and functional motion in both athletes and nonathletes.7,8 In addition, findings of a recent systematic review provide support for arthroscopic treatment of ankle impingement.9 Although arthroscopic treatment is effective in nonathletes and recreational athletes,10 there is a paucity of data on the efficacy of this procedure and on time to return to play (RTP) in professional football players.
We conducted a study to evaluate the outcomes (pain, ROM, RTP) of arthroscopic débridement for anterior ankle impingement in National Football League (NFL) players. We hypothesized that arthroscopic decompression of anterior ankle impingement would result in significant, reliable, and durable improvement in pain and ROM, and would allow NFL players to return to their preoperative level of play.
METHODS
After this study was granted Institutional Review Board approval, we retrospectively reviewed a consecutive series of arthroscopically treated anterior ankle impingement athletes by a single surgeon (JPB). Indications for surgery were anterior ankle impingement resulting in ankle pain and decreased ROM that interfered with sport. Active NFL players who underwent ankle arthroscopy for symptomatic anterior ankle impingement were included. Excluded were players who underwent surgery after retirement or who retired before returning to play for reasons unrelated to the ankle. Medical records, operative reports, and rehabilitation reports were reviewed.
