Anterior ankle impingement is pain at the front of the ankle when the shin and the top of the foot pinch together, as in squatting, lunging, landing or climbing stairs. It is caused by bone spurs on the front of the tibia or talus (sometimes called footballer’s ankle) or by thickened scar and synovial tissue, often after repeated sprains.1,4 It is a common cause of chronic ankle pain in athletes, and arthroscopic treatment gives good results with low complication rates.11,19
- Pain at the front of the ankle with deep bending (lunging, squatting, sprinting, stairs)
- Bony spurs or scar tissue, often after repeated sprains1,4
- Oblique X-rays and MRI help confirm it2,9
- Most improve with rehab and activity changes first1
- Arthroscopic debridement relieves pain in most; results are better without arthritis12,19
Types
- Bony (anterior or anteromedial) impingement: spurs on the front of the tibia and talus, from repetitive impact and pushing the ankle into deep dorsiflexion.1,18
- Soft-tissue (anterolateral) impingement: thickened synovium and scar tissue in the outer gutter of the ankle, usually after a sprain and often with some instability.4
- Bassett ligament impingement: a separate lower band of the anterior tibiofibular ligament that can rub on the talus.6 A thickened band has been linked to cartilage lesions that MRI can miss.8
Symptoms
- Pain at the front of the ankle with lunging, squatting, sprinting, uphill running or stairs
- Reduced ability to bend the ankle upward
- Swelling after activity
- Tenderness over the front or front-outer ankle
Diagnosis
Dr. Dold examines tenderness and motion and checks for ankle instability. Standard X-rays can miss spurs on the inner side, so an oblique view is recommended.2 MRI shows soft-tissue thickening, cartilage damage and ligament injury;10,24 it can miss soft-tissue impingement (42% sensitivity in one study),23 so the exam remains central. Dynamic ultrasound can also help.9
Non-surgical treatment
Initial treatment includes activity modification, physical therapy and strengthening, a brace and anti-inflammatory medicines.1 A cortisone injection can help confirm the diagnosis and calm inflamed tissue. Underlying ankle instability is addressed with balance and strengthening work.9
Arthroscopic surgery
When symptoms persist, arthroscopy removes the spurs and inflamed or scarred tissue through two small incisions:2,5
- Arthroscopic treatment provides good patient satisfaction with low complication rates.11
- Removing tibiotalar spurs gives good to excellent results in most patients with rapid recovery.18 Results were good or excellent in 77% of ankles with early arthritis and 53% with moderate arthritis, and some spurs recurred.12
- For soft-tissue impingement, 26 of 31 patients had good or excellent results and returned to sport at about 6 weeks,20 pooled scores averaged 90.1,21 and scores improved from 59 to 88.22 Higher BMI and male sex predicted less improvement.13
- A lateral ligament repair can be added if the ankle is unstable.5 Outcomes are less favorable with instability or joint-space narrowing,19 and arthritis is a key prognostic factor.3 See ankle arthritis.
In-office needle arthroscopy is a newer option with early promising results,14 though evidence is still limited.15 Dr. Dold performs ankle arthroscopy in the operating room and can discuss a referral if you are interested in needle arthroscopy. Across nearly 8,000 ankle arthroscopies, major complications occurred in only 0.2%;16 rare problems include nerve irritation and, very rarely, a blood-vessel injury after removing large spurs.17
Recovery
- Walking in a boot or shoe as comfortable within days, with early motion encouraged.1
- Return to sport often around 6 weeks after soft-tissue debridement,20 sometimes longer after larger spur removal.
Dr. Dold reviews your timeline based on your findings.
Frequently asked questions
What is footballer’s ankle?
Bone spurs at the front of the ankle from repeated impact and deep bending, common in soccer players and other athletes. The spurs pinch tissue when the ankle bends upward.
Do bone spurs need to be removed?
Not always. Spurs that don’t cause pain can be left alone. Surgery is considered when they limit motion and cause pain despite rehab.
Can scar tissue after a sprain cause ongoing pain?
Yes. Thickened tissue in the front-outer ankle can pinch with movement after a sprain and is a common cause of lingering pain.
How long is recovery after ankle arthroscopy?
Many people walk within days and return to sport in about 6 weeks after soft-tissue debridement, with longer recovery after larger procedures.
Will the spurs come back?
Some regrow over time, but most patients keep their pain relief, especially when there is no significant arthritis.
