Meniscoid lesion of talofibular joint of ankle:
Chronic ankle pain and swelling over anterolateral aspect of ankle – often accompanied by subjective feeling of ‘instability’ and ‘giving way’ following history of ankle sprain.
Thought to be due to presence of rare lesion between fibula and talus – postulated to have two causes:
1) Secondary to traumatic synovial thickening small portion of inflammatory infiltrate persists between talus and lateral malleolus becomes hyalinised due to pressure symptoms
2) Meniscoid lesion is tear of anterior tibiofibular ligament fragment between talus and lateral malleolus symptoms
Surgical excision is needed
