Episode notes
Ankle Arthritis Epidemiology & Etiology
- Ankle arthritis is less common than knee or hip osteoarthritis.
- Post-traumatic arthritis is the most frequent type, while osteoarthritis makes up under 10% of cases.
Pathoanatomy of Ankle Arthritis
- Non-anatomical fracture healing disrupts ankle mechanics by changing joint contact forces.
- Cartilage loss leads to joint space narrowing, subchondral sclerosis, and osteophyte formation.
Ankle Osteology
- The ankle, a hinge joint, comprises the tibia, talus, and fibula.
- The talar dome has a biconcave structure with a central sulcus.
