Anterior Ankle Impingement

---

Anterior ankle impingement occurs when structures at the front of the ankle joint are compressed or irritated — particularly during upward ankle movement (dorsiflexion). It can involve soft tissue (thickened joint lining, scar tissue) and/or bony spurs. Common in runners, dancers, footballers, and other athletes.

Symptoms

• Sharp or aching pain at the front of the ankle
• Pain or restriction when bending the ankle upward (stairs, lunging, squatting)
• Swelling or thickening at the front of the joint
• A sensation of blocking, catching, or pinching
• Stiffness — especially in the morning or after exercise

Causes

• Repeated ankle sprains or chronic instability
• Repetitive dorsiflexion in sports or dance
• Bony spurs (osteophytes) along the front of the tibia or talus
• Scar tissue, inflamed synovium, or joint capsule thickening
• Post-traumatic changes after fractures or cartilage injury

Non-Surgical Treatment

• Activity modification
• Anti-inflammatory medication (NSAIDs)
• Physiotherapy — ankle mobilisations and strengthening exercises
• Supportive footwear or orthotics
• Ultrasound-guided steroid injections to reduce inflammation

Surgery

If symptoms persist, surgery to remove the impinging structures may be recommended:

• Arthroscopic debridement (keyhole surgery): Removal of soft tissue impingement — thickened synovium, scar tissue, or loose bodies.
• Arthroscopic or open cheilectomy: Removal of bony spurs from the front of the tibia or talus.
• Associated cartilage damage or joint surface issues may also be treated.

Recovery

Timeframe	What to Expect
0–2 weeks	Post-operative boot. Partial weight-bearing with crutches.
2 weeks	Wound review. Transition to supportive shoes. Physiotherapy begins.
2–6 weeks	Increased walking and functional movement.
6–12 weeks	Return to normal activities. Most patients resume low-impact sport.
12+ weeks	Gradual return to high-impact activity or full sport if pain-free.
