Pain at the front of the ankle when bending the foot upward, during sprinting, deep squats, or kicking a football, particularly in athletes who have played contact or field sports for years, is the hallmark of anterior ankle impingement. Often called footballer’s ankle, it is a common cause of persistent ankle pain in footballers, cricketers, and dancers.
Anterior ankle impingement occurs when soft tissue or bony spurs at the front of the ankle joint are pinched during dorsiflexion, the motion of bending the foot upward. Bony spurs on the anterior tibia or talar neck develop in response to years of repetitive microtrauma and capsular traction, progressively encroaching on the space at the front of the joint.
Bony (Hard) Impingement: Caused by osteophytes, bony spurs developing on the anterior edge of the distal tibia and the dorsal neck of the talus, that mechanically compress and impinge against each other during dorsiflexion. This is the classic footballer's ankle pattern. The spurs are clearly visible on plain X-rays and respond well to arthroscopic removal.
Soft Tissue Impingement: Caused by hypertrophied synovial tissue, capsular scarring, or thickened anterolateral ligamentous bands that are pinched in the anterior ankle joint during dorsiflexion. This pattern may occur without obvious bony spurs and can be more subtle on imaging. The diagnosis is often confirmed at arthroscopy.
Combined Bony and Soft Tissue Impingement: Both bony spurs and thickened soft tissue are present and contributing to the impingement. Common in patients with a long history of ankle sprains who have developed both synovial hypertrophy and progressive osteophyte formation.
Repetitive dorsiflexion loading in football, basketball, and ballet causes progressive spur formation at the front of the ankle joint. A history of ankle sprains is a common contributing factor as the repeated capsular traction stimulates bone spur growth.
Plain X-rays identify anterior tibial and talar osteophytes. MRI assesses soft tissue impingement and any associated cartilage or ligament pathology.
Dr. Kushalappa performs ankle arthroscopy for anterior ankle impingement, removing bony spurs from the anterior tibia and talus and excising any impinging soft tissue using keyhole instruments. This is a day procedure under general anaesthesia with a rapid recovery and high success rate in appropriately selected patients. Return to full sport is expected within 6 to 8 weeks.
If managed early, it responds well to arthroscopic treatment. If neglected, progressive spur growth can lead to significant dorsiflexion restriction and secondary cartilage damage. Athletes who notice progressive worsening with sport should seek early assessment.
