This systematic review and meta-analysis evaluated the diagnosis, intervention, and prognosis of anterior ankle impingement syndrome (AAIS) in 5,217 patients, primarily athletes. Key findings indicate that dynamic ultrasound has 83% sensitivity for anterolateral impingement, while MRI shows 92% sensitivity for osteophytes. Optimal interventions include arthroscopic debridement and combined reconstruction for severe cases.
Key findings
- Dynamic ultrasound sensitivity for anterolateral impingement is 83% (95% CI 78-88).
- MRI sensitivity for osteophytes/cartilage is 92% (95% CI 89-95).
- Arthroscopic 3-portal debridement yields an AOFAS score increase of +30.5 with a 10% recurrence rate.
- Anteromedial AAIS has a recurrence rate of 28.6% in males with BMI > 26.
Why it matters
Understanding subtype-specific management of AAIS is crucial for optimizing treatment outcomes and minimizing recurrence rates. Accurate diagnosis and tailored interventions can significantly improve patient quality of life, particularly in athletic populations.
