What is ankle osteoarthritis?
Crurarthrosis is a degenerative disease of the ankle joint with destruction of the cartilage coating. Unlike knee and hip osteoarthritis, it is post-traumatic in 80% of cases — it develops after ankle fractures and ligament injuries.
Surgical treatment includes arthrodesis (joint fusion) or joint replacement. Arthrodesis completely eliminates mobility, while the ankle prosthesis is less reliable than those for the knee or hip.
Causes:
- Post-traumatic (80%) — after fractures, dislocations
- Chronic instability — recurrent subluxations
- Osteochondral lesion — cartilage defect of the talus
- Rheumatoid Arthritis
- Foot deformity — flatfoot, varus
Symptoms:
- Pain when walking, especially on uneven surfaces
- Joint swelling by the end of the day
- Morning stiffness
- Limited dorsiflexion of the foot
- Limping during exacerbations
Facts about crurarthrosis
- ICD-10: M19.07
- Cause: 80% post-traumatic
- Age: younger than with gonarthrosis
- Arthrodesis: loss of mobility
- Prosthesis: less reliable than knee
Ankle osteoarthritis: treatment options and what is known about them
The treatment plan is made by the clinic doctor after an examination and a review of your images. The table shows the options usually discussed for this diagnosis and how well they have been studied.
| Option | What to expect | How well studied |
|---|---|---|
| Exercise therapy and physiotherapy | Reduces pain, strengthens muscles, improves function; the basis of treatment | Well studied, recommended |
| Braces, splints, insoles | Offload and stabilise, reduce pain under load | Moderate evidence |
| Painkillers and NSAIDs | Ease pain during flare-ups; long-term use is limited by side effects | Moderate evidence |
| Corticosteroid injection | Quickly reduces inflammation and pain, the effect is often temporary; frequent injections are undesirable | Limited or conflicting evidence |
| Hyaluronic acid | Reduces pain for a few months in some patients | Limited or conflicting evidence |
| PRP / CGF | Concentrate from your own blood; may reduce pain, growth of new tissue has not been shown | Limited or conflicting evidence |
| Ankle fusion or ankle replacement | If conservative treatment does not help or there is an indication | When indicated — the doctor decides |
We send your request to several partner clinics. Some will suggest conservative treatment or injections, others surgery; each clinic quotes its own conditions and price. We help you compare the options.
Regenerative methods: realistic expectations
In osteoarthritis, regenerative injections can reduce pain and improve function for a period of several months to a year. PRP in knee osteoarthritis is the best studied: in a number of trials it reduced pain more than hyaluronic acid, but not in all of them. Restoration of damaged cartilage has not been shown. Cell-based methods (BMAC, MFAT) are less well studied and more expensive. Exercise and weight control remain the basis of treatment — injections add to them rather than replace them.
When surgery is discussed. Surgery is discussed when marked pain and restricted movement do not improve after 3–6 months of conservative treatment, and in advanced stages with deformity.
If an injection helps, the effect usually builds up over 6–12 weeks, and the result is assessed after 2–3 months. No clinic can guarantee a result.
Good to know: diagnosis, self-help, outlook
How to tell ankle arthritis from similar conditions
Ankle arthritis most often develops after fractures and repeated sprains, less often without injury. Pain occurs when walking, especially on uneven ground and stairs, with swelling by evening and stiffness in the morning. Chronic instability after sprains shows as the ankle giving way, and posterior tibial tendinopathy as pain on the inner side. A standing X-ray shows joint-space narrowing and osteophytes; CT or MRI shows cartilage and bone cysts.
What you can do yourself
Choose stable shoes with a firm heel counter and a rocker sole and, if needed, insoles or a brace. Lose weight and replace running and jumping with cycling and swimming. Balance and calf exercises reduce the load on the joint.
Outlook and timelines
Suitable footwear, a brace and exercise help many patients manage without surgery for a long time. Corticosteroid injections relieve pain for weeks; evidence for hyaluronic acid and PRP in the ankle is limited. With severe pain, arthroscopy, ankle fusion or ankle replacement are discussed.
Who it is not suitable for and possible risks
Contraindications
- Active infection — at the injection site or systemic, with fever.
- Active cancer or ongoing chemotherapy.
- Blood clotting disorders or a low platelet count. Anticoagulants are discussed with the physician.
- Pregnancy and breastfeeding — the procedure is usually postponed.
- A corticosteroid injection into the same area in recent weeks.
- A complete tendon or ligament rupture with loss of function — surgical repair is usually needed.
Possible risks
- Pain and swelling at the injection site for 1–3 days.
- Bruising where blood or fat tissue is taken.
- Rarely, infection. The procedure is therefore performed under sterile conditions with ultrasound or X-ray guidance.
- The effect may be absent or smaller than expected.
If any of these apply to you, mention it in your request. The coordinator will check with the clinic physician whether treatment is possible. Contact a coordinator.
Scientific evidence
Studies of regenerative methods show mixed results. Clinic physicians rely on research including the following:
- Monto RR. Platelet-rich plasma and plantar fasciitis. Sports Med Arthrosc Rev, 2013.
- Sheth U et al. Efficacy of autologous platelet-rich plasma use for orthopaedic indications: a meta-analysis. J Bone Joint Surg Am, 2012.

Frequently Asked Questions about Treatment of Ankle Osteoarthritis
RegenPAS is a patient service centre in Munich, not a clinic. We review your images and symptoms and send a request to several partner clinics at once. Clinics that can accept you send their own conditions and price; prices differ between clinics, and you choose the option that suits you. The coordinator replies within 24 hours, and a clinic physician’s preliminary opinion follows in 1–3 business days. We then arrange the appointment, visa invitation, interpreter, transfers and accommodation. Treatment decisions are made by the clinic physician. Contact a coordinator.
Your MRI (or CT, X-ray) report and the images if you have them, plus a short description of your symptoms and previous treatment. Send them via the form on the website — the assessment is free and without obligation: the coordinator replies within 24 hours, and the clinic physician’s preliminary opinion follows in 1–3 business days.
The cost depends on the method, the diagnostics needed and the clinic itself: prices differ between clinics. We request offers from several clinics and send you their conditions and quotes so you can compare. Price guidance is on the treatment cost page. For an outpatient procedure, 2–3 days in Munich are usually enough: examination, procedure and follow-up visit.
Clinic and method matching — free of charge
Describe your case and attach your MRI report. We will identify clinics that use the relevant methods and forward your request to them. No obligation; we reply within 24 hours.
