Understanding Wear-and-Tear Arthritis of the Ankle
Ankle osteoarthritis is the gradual breakdown of the cartilage that cushions the ankle joint. Unlike knee and hip arthritis, it most often develops years after an injury such as a fracture or repeated sprains. It causes pain, stiffness, and swelling that can make walking on uneven ground difficult. Bracing, footwear, and injections can help many people stay active.
Causes
Prior ankle fractures.
Repeated ankle sprains and chronic ankle instability.
Inflammatory arthritis, such as rheumatoid arthritis.
Gout or hemochromatosis.
Joint malalignment.
Symptoms
Deep ankle pain with walking, especially on stairs, slopes, or uneven ground.
Stiffness after rest and in the morning.
Swelling around the ankle.
Reduced ability to bend the ankle up and down.
Bone spurs that cause pinching pain at the front of the ankle.
Imaging Studies to Consider
Standing (weight-bearing) X-rays are the main test and show joint space narrowing, bone spurs, and alignment.
CT scan helps evaluate bone and plan surgery.
MRI is used if cartilage or ligament injury needs closer evaluation.
Physical Therapy, Home Exercise & Other Conservative Techniques
Physical Therapy
Ankle and hip strengthening.
Balance and proprioception training.
Gait training.
Home Exercise Program
Range-of-motion exercises.
Low-impact aerobic exercise such as cycling or swimming.
Other Studied Techniques
Supportive shoes with a rocker-bottom sole.
Ankle brace or custom ankle-foot orthosis.
Weight management.
A cane on the opposite side for longer walks.
Interventional Treatment Options
Ultrasound- or x-ray-guided corticosteroid injection: Reduces joint inflammation and pain, often for weeks to months.
Hyaluronic acid injection: May help some people; evidence in the ankle is less robust than in the knee.
Platelet-rich plasma (PRP): Current evidence for foot and ankle arthritis is inconsistent, and PRP is not recommended over standard treatments at this time.
Surgical referral: For advanced arthritis that limits daily life, we refer to a foot and ankle surgeon to discuss options such as cleanup of bone spurs, ankle fusion, or ankle replacement.
Neuromodulation: Spinal Cord & Peripheral Nerve Stimulation
For persistent ankle pain after surgery or when surgery isn't an option, peripheral nerve stimulation of the nerves around the ankle, or spinal cord or dorsal root ganglion stimulation, may be considered in select patients.
Evidence Base: Guidelines & Levels of Evidence
Corticosteroid injection: Level III · Observational studies; extrapolated from other joints
Hyaluronic acid injection: Level II · Small randomized trials with mixed results
Platelet-rich plasma (PRP): Level I · Grade D · ASPN 2024 consensus guideline: not recommended over conventional therapy for foot arthritis
Bracing and footwear: Level III · Observational studies
Evidence levels and guideline citations above are summarized for general clinical reference based on the literature and major society guidelines available at the time of writing. Guidelines are periodically updated; please verify current recommendations before relying on this summary for clinical decision-making.
Pain Psychology Techniques
Cognitive behavioral therapy (CBT) for pain-related worry and activity avoidance.
Graded activity pacing.
Mindfulness-based stress reduction.
Relaxation training and diaphragmatic breathing.
Non-Opioid Medication Options
Anti-inflammatory and analgesic options
NSAIDs like ibuprofen or naproxen.
Acetaminophen.
Topical treatments
Topical diclofenac gel applied to the ankle.
For chronic pain
Duloxetine, an SNRI approved for chronic musculoskeletal pain.
