Ankle Arthritis

Ankle arthritis is a degenerative condition that occurs when the protective cartilage covering the bones of the ankle joint wears down, leading to painful bone-on-bone contact. Unlike hip and knee arthritis, ankle arthritis is most commonly post-traumatic—developing years after an ankle fracture, severe sprain, or ligament injury.

The ankle joint bears tremendous force with every step, making cartilage damage particularly debilitating. Patients often experience progressive pain, stiffness, and swelling that worsens over time and limits walking, climbing stairs, and standing. At Mountain Spine & Orthopedics, our fellowship-trained foot and ankle specialists use advanced imaging and comprehensive evaluation to determine the stage of your arthritis and create a personalized treatment plan.

Treatment options range from conservative measures like bracing and injections to advanced surgical solutions including ankle arthroscopy and total ankle replacement when necessary.

Ankle arthritis symptoms typically develop gradually and worsen over time. Recognizing these signs early allows for intervention that can slow progression.

• Deep, aching pain in the ankle, especially with weight-bearing activities
• Stiffness that's worse in the morning or after rest
• Swelling around the ankle joint
• Grinding or catching sensation (crepitus) with movement
• Decreased range of motion—difficulty pointing or flexing the foot
• Pain that worsens with activity and improves with rest
• Ankle instability or a feeling the joint may give way
• Visible deformity in advanced cases
• Difficulty walking on uneven surfaces

If you're experiencing these symptoms, a second opinion from our specialists can help clarify your diagnosis and treatment options.

Understanding the causes of ankle arthritis helps identify who is at risk and how to potentially slow progression.

• Previous ankle fracture: The most common cause—fractures that involve the joint surface significantly increase arthritis risk
• Repeated ankle sprains: Chronic ankle instability damages cartilage over time
• Inflammatory arthritis: Rheumatoid arthritis and other inflammatory conditions
• Osteoarthritis: Age-related wear and tear
• Obesity: Excess weight accelerates joint degeneration
• Ankle malalignment: Abnormal mechanics from flat feet or other deformities
• Avascular necrosis: Loss of blood supply to the talus bone

Accurate staging of ankle arthritis guides treatment decisions. Our comprehensive evaluation includes:

• Physical examination: Assessing range of motion, stability, swelling, and areas of tenderness
• Weight-bearing X-rays: Essential for visualizing joint space narrowing, bone spurs, and alignment
• CT scan: Provides 3D bone detail for surgical planning
• MRI: Evaluates cartilage, ligaments, and soft tissue; we offer complimentary MRI reviews

We stage ankle arthritis from early (mild cartilage wear) to end-stage (bone-on-bone contact) to recommend the most appropriate treatment level.

Ankle arthritis treatment is tailored to the stage of disease and your activity goals.

Non-Surgical Treatment

• Activity modification: Avoiding high-impact activities that worsen symptoms
• Supportive footwear: Stiff-soled shoes or rocker-bottom shoes reduce ankle motion
• Bracing: AFO (ankle-foot orthosis) or lace-up braces provide stability and reduce pain
• Physical therapy: Strengthening exercises and range-of-motion work
• Anti-inflammatory medications: NSAIDs for pain and swelling
• Corticosteroid injections: Image-guided injections can provide months of relief
• Viscosupplementation: Hyaluronic acid injections may improve joint lubrication

Surgical Treatment

When conservative measures fail, surgical options include:

• Ankle arthroscopy: Minimally invasive surgery to remove bone spurs and loose bodies
• Ankle fusion (arthrodesis): Eliminates pain by fusing the joint bones
• Total ankle replacement: Ankle arthroplasty preserves motion while relieving pain

Pain from ankle arthritis results from multiple factors: bone-on-bone contact where cartilage has worn away, inflammation of the joint lining (synovium), and irritation from bone spurs. Pain is typically activity-related—worse with walking and standing, better with rest. In advanced stages, pain may occur at rest or disrupt sleep.

Protecting your ankle joint starts with treating injuries properly and maintaining overall joint health.

• Treat ankle injuries promptly: Proper treatment of fractures and sprains reduces future arthritis risk
• Address ankle instability: Recurrent sprains damage cartilage over time
• Maintain healthy weight: Reduces stress on the ankle joint
• Strengthen ankle muscles: Strong muscles provide better joint support
• Wear supportive footwear: Proper shoes reduce abnormal joint stress
• Correct foot deformities: Treat flat feet or high arches that alter ankle mechanics
