Foot and Ankle Arthritis

In this episode of BIPEDAL, we take a comprehensive look at arthritis of the foot and ankle, a common condition that can significantly affect mobility and quality of life.  Foot arthritis is actually quite common, particularly in adults over the age of 50, while ankle arthritis is less frequent but often more debilitating when it occurs. Osteoarthritis is the most common joint disease worldwide, affecting hundreds of millions of people. In the foot alone, imaging studies suggest that roughly one in five adults over 50 show signs of arthritis, although not all cases produce symptoms. Ankle arthritis affects approximately 1% of the population, and unlike hip or knee arthritis, the majority of ankle arthritis cases are post-traumatic, meaning they develop after an injury such as an ankle fracture or severe sprain. Arthritis typically begins with breakdown of the protective cartilage inside the joint, which normally allows smooth, pain-free movement. As cartilage deteriorates, the joint space narrows and the bones begin to experience increased mechanical stress. Over time this can lead to bone spurs, stiffness, loss of motion, and chronic pain. There are different causes of arthritis, including: Primary osteoarthritis, related to age and long-term wear Post-traumatic arthritis, often following fractures or ligament injuries Inflammatory arthritis, such as rheumatoid arthritis or psoriatic arthritis Biomechanical causes, including deformities or abnormal foot structure Common symptoms of foot and ankle arthritis include: Pain during walking or standing Stiffness in the affected joint Swelling and inflammation Loss of joint motion Progressive deformity in advanced cases Treatment generally begins with conservative management aimed at reducing pain and improving function. These strategies may include activity modification, supportive footwear, custom orthotics, bracing, anti-inflammatory medications, and occasionally injections to reduce inflammation. When symptoms become severe or conservative treatments fail, surgical options may be considered. These procedures can include joint debridement, realignment procedures, joint fusion, or in certain cases joint replacement, particularly for the ankle. The episode emphasizes that treatment decisions are individualized and depend on the severity of arthritis, the joints involved, and the patient’s activity level and goals. Key Takeaways The foot contains 33 joints, making arthritis a common source of foot pain. Approximately 20% of adults over 50 show signs of foot arthritis on imaging. Around 70–80% of ankle arthritis develops after trauma, such as fractures or severe sprains. Symptoms typically include pain, stiffness, swelling, and decreased mobility. Conservative treatments often provide relief, but surgical options exist for advanced cases. This episode provides listeners with a clear overview of how arthritis develops in the foot and ankle and the wide range of treatment options available to maintain mobility and quality of life.
