Aetiology of Ankle Osteoarthritis

Emma Walker

Ankle osteoarthritis is a chronic condition that affects about 1% of the population, with an estimated prevalence of 30 cases per 100,000 residents, and accounts for between 2% and 4% of all Osteoarthritis Patients (OA). Ankle osteoarthritis is less prevalent than knee and hip osteoarthritis, according to cadaver, radiological, and clinical investigations. This is paralleled in clinical practise, where symptomatic knee osteoarthritis is 8 to 9 times more common than ankle osteoarthritis, and complete knee work is performed around 24 times more than arthrodesis and arthroplasty combined. Ankle OA is very debilitating in advanced stages and can have similar repercussions on quality of life as severe hip osteoarthritis, advanced kidney failure, or congestive heart failure. While its clinical impact on patients has not been considered particularly relevant, it is very debilitating in advanced stages and can have similar repercussions on quality of life as severe hip osteoarthritis, advanced kidney failure, or congestive heart failure.
