Ankle Osteoarthritis (MSK Patient Portal)

Osteoarthritis (OA) is a condition that affects the joints causing pain and stiffness.

It is normal to expect some degree of osteoarthritis as we get older. Between bones, there is cartilage which protects the bones and provides some shock absorption. With osteoarthritis, this cartilage gradually wears away and allows some bone to bone contact.

Over time, this causes bony changes, pain and loss of function at the affected joint.  

What is ankle osteoarthritis?

Ankle osteoarthritis occurs when the protective cartilage that cushions the ends of the tibia, fibular and talus wears down over time, leading to bone to bone contact and inflammation. With ankle osteoarthritis it may be uncomfortable to walk and climb stairs due to pain and stiffness with ankle movements. Ankle osteoarthritis can be chronic in which it develops slowly over time, or as a result of trauma or injury.

Ankle osteoarthritis affects approximately 1% of the population. There is a higher incidence of ankle osteoarthritis in women compared with men and is more common in those over 45 years old. 

Causes 

Approximately 90% of people with ankle arthritis have one of two main risk factors: previous joint trauma or an underlying medical condition. The remainder of people usually have other risk factors, such as family history of osteoarthritis. 

Risk factors include: 

  • Injury: a traumatic injury such as a fracture or a severe ankle sprain can lead to osteoarthritis of the ankle over time. 
  • Inflammatory Arthritis: The ankle joint can be affected in patients with medical conditions causing inflammatory arthritis, for example rheumatoid arthritis, psoriatic arthritis or gout. 
  • Infection / Bleeding: Although very rare infection or bleeding within the ankle joint caused by a medical condition can result in ankle arthritis.  
  • Age: it is more common in older adults, although it can affect any age. 
  • Obesity: The ankle bears up to 5 times a person’s body weight during walking. If you are overweight this can lead to greater stress and load going through your ankle joint due to the changes in foot mechanics.  
  • Genetics: if you have a family history of osteoarthritis you may be more at risk of developing ankle arthritis.  

Symptoms

The main symptoms of osteoarthritis of the ankle are: 

  • Pain: worse in the mornings or after periods of activity 
  • Stiffness: worse in the morning or after periods of rest 
  • Swelling: one side or across the ankle 
  • Restricted range of movement: limited movement up or down at the ankle and it can feel / sound like it crunches.  
  • Giving way of the ankle 
  • Difficulty with weight bearing activity: due to pain, stiffness and reduced range of movement 

How long will it take to get better? 

There is no cure for osteoarthritis of the ankle, but there is a lot that you can do to improve your symptoms. Self-help or self-management is very important to relieve pain, stiffness and reduce your chances of your arthritis becoming worse. 

What can I do to help my ankle osteoarthritis? 

Treatment is aimed at reducing the stress/ load through the affected joint to reduce inflamation and improving strength around the affected joint.  

Changes in lifestyle can also be helpful to aid in your recovery. The one person who can help you manage your symptoms is you. 

Footwear  

One of the most important changes you can make is to your footwear. 

  • Avoid walking in bare feet 
  • Avoid high heeled shoes or shoes with a flexible sole as these place increased stress on the joints of the forefoot.  
  • Avoid very flat shoes 

Look for a shoe that has the following qualities; 

  • Heels should be broad and around 1.5 inches high. 
  • Soles should be firm and non-pliable. 
  • Cushioned soles such as running shoes can help with shock absorption 
  • Deep fitting footwear or boots may provide greater support around your ankle. 
  • Lacing or Velcro straps to hold the shoe firmly to the foot. E.g. running or walking shoe/boot. 
  • The forefoot of the shoe should have a small rocker to aid with the walking cycle and reduce pain. 

Watch our footwear advice video below, or see our section with further footwear advice.

Topical creams/gels 

Applying anti-inflammatory gel across ankle joint can provide some symptomatic relief in the short term. 

Weight management 

If you have a higher than average body mass index (BMI) you are more at risk. Please see the weight management section of our foot and ankle pain self-help page for further support with managing weight.  

Ice 

Icing can be beneficial in the first 2-3 days following injury or to help manage any flare ups of pain. Please click here for more advice on how to ice your foot. Some people do find continual benefit of regularly icing for several weeks following the injury. 

Activity modification 

Avoiding high impact activities and replacing with low impact exercise (e.g. replace running with walking or swimming or cycling) 

Strengthening and stretching exercises  

Targeted strengthening and stretching exercises for the muscles in and around your foot and ankle can help to improve your symptoms. Local NHS Ayrshire & Arran podiatrists have devised exercise videos to help with strengthening the correct muscles.

See exercise videos at the foot of the page.

Foot orthoses  

Foot orthoses may be considered if self-management and exercises have not improved your symptoms. Your local MSK podiatrist may prescribe some foot orthoses to wear in your shoes to try and offload the joint.   

Ankle brace 

An ankle brace may be considered if self-management and exercises have not improved your symptoms. Your local Podiatrist or Orthotist may be able to fit your ankle with an appropriate ankle brace to try and support the joint.  

Oral pain medication 

Non-steroidal anti-inflammatories medication can sometimes be prescribed by your GP. Please see the pain management section of our foot and ankle pain self-help page for more information.

Corticosteroid injections 

Corticosteroid injections although more invasive, can reduce pain and inflammation in the short term, if appropriate they can be provided by your MSK Podiatrist or an appropriately trained professional.   

Investigations and surgery 

Do I need a scan? 

Ankle osteoarthritis can be diagnosed via a physical examination and patient history. X-rays can confirm changes within the joint and indicate severity. MRI and Diagnostic Ultrasound scans can also indicate osteoarthritis as well as confirm active synovitis (inflammation of joint lining).  

Will I need surgery? 

Surgical management is not usually considered unless you have tried all of the above measures and continue to have difficulty walking. If the severity of the arthritis is significant with minimal scope to improve function then it may be appropriate for a referral to an orthopaedic surgeon to consider a surgical intervention. Surgical options for ankle arthritis may include arthroscopy, ankle fusion or ankle replacement. 

Exercises 

The exercises below have been provided to help with your ankle osteoarthritis. If there is any doubt about your fitness to do these exercises then please discuss this with your GP.  

You may find that these exercises may slightly increase your symptoms initially. However you should find the exercises themselves will become easier to do and that you begin to move your foot and ankle more easily.  The exercises can take up to 12 weeks for you to notice a great improvement.  

If these exercises cause a large increase in your pain or after 12 weeks there are no noticeable changes in your day to day symptoms then please contact your GP or NHS inform for more advice. 

Pain during exercise

A horizontal bar chart representing pain levels during exercise:

Green section labeled "0-3: Minimal Pain".
Yellow section labeled "4-5: Acceptable".
Red section labeled "6-10: Excessive".
At the top, there's a reference scale "0 = no pain, 10 = worst pain imaginable".

Within the scale, aim to stay in the green or amber boxes. If you are in the red area then you can modify the exercises by:

  • reducing the amount of movement during an exercise
  • reducing the number of repetitions
  • reducing the weights
  • reducing your speed
  • increasing rest time between sets

Pain after exercise

Your pain or other symptoms should return to your pre-exercise baseline within 30 minutes of exercising. On the morning after your exercises, you should not feel an increase in pain or stiffness that lasts longer than 60 minutes.
