The ankle is a complex joint formed by three bones: the tibia forms the roof and medial side, the fibula is a buttress for the lateral side, and the talus acts as the hinge inside the mortise. It is a table joint that allows for the flexion and extension of the ankle, with a minimal side-to-side motion. It is largely unaffected by arthritis in the way that the hip and knee are, and simple wear and tear arthritis is uncommon.

Arthritis is the wear of cartilage inside the joint. The cartilage acts as a nearly frictionless surface to allow motion. When the cartilage is gone, the bone rubs against the bone, which is painful. Inflammation within the joint is also painful.

ankle arthritis

Almost half of people in their 60s and 70s have arthritis in the foot or ankle, but not all these people notice symptoms or experience pain.

Seventy percent of arthritis in the ankle is caused by prior trauma, known as post-traumatic arthritis. This can be traumatic as serious as a fracture that disrupts the end of the tibia, a simple fracture to the fibula, or even an ankle sprain leading to chronic instability. In its early form, it may be isolated to a bone spur on the anterior portion of the joint, leading to decreased range of motion and a sensation of “pinching.” More severe arthritis is complete cartilage loss and cyst formation.


A set of high-quality weight-bearing (standing) x-rays are required for diagnosis, as well as a thorough physical examination. Sometimes, an MRI and CT scan may be necessary.


Oral anti-inflammatories and ice
Oral anti-inflammatories and ice help to minimize the pain significantly. Two Aleves twice a day for two weeks as a trial can show how much NSAIDs will minimize pain. Topical NSAIDs are also available by prescription. Ice should always be wrapped in a tea towel and applied for no more than fifteen minutes every hour to prevent frostbite. It should be done at least twice a day but not more than once an hour.

Activity modification
Activity modification will help to alleviate pain. Impact activities will always be more painful on an arthritic ankle. Cross-training with swimming or elliptical machine, and avoidance of aggravating activities, can result in less pain.

Temporary immobilization
Temporary immobilization with a brace or boot can help during severe flares of pain.

Physical therapy
Physical therapy helps to retrain gait and strengthen the muscles around the ankle to normalize motion and minimize pain. It does not reverse arthritis, but can greatly decrease the pain.

Orthotics to normalize the foot’s contact with the ground and offload areas of pressure.

Injections can be performed. There are three main types of injections used for arthritis:

  • Anti-inflammatory injections: these are steroid injections, which decrease inflammation. They may help some of the pain from swelling within the joint. They do carry the risk of damage to the cartilage over time and should be used judiciously.
  • Lubricant injections: these are made of glycoproteins that occur naturally in joint fluid. Arthritis disrupts the normal concentrations of glycoproteins in our joint fluid, and the lubricant injections help to restore a more normal lubricant joint fluid. These are off-label in the ankle and may not be covered by insurance but many patients find them to be helpful.
  • Biologic injections: these include stem cells and PRP (platelet-rich plasma). Without help, cartilage is not repaired by the body. The goal of these injections is to stimulate the body’s healing responses above normal levels to allow for the healing of injured cartilage. PRP, which is commonly used, is drawn from your own blood to stimulate the inflammatory pathways that create cartilage. This may allow for some healing. These are not usually covered by insurance.

Occasionally surgery is necessary when the pain is not able to be treated. The specific surgery required is dictated by the severity of arthritis, as well as other factors.

For young patients with only an anterior osteophyte or bone spur, simple removal of the bone spur may alleviate a significant portion of the pain and allow for a better range of motion.

For severe arthritis, an ankle fusion or replacement may be necessary.–conditions/arthritis-of-the-footand-ankle/

A fusion welds the joint together to completely rid the ankle of any arthritis or pain. The numerous joints that surround the ankle allow for near-normal motion afterward. This surgery does not need to be redone.

Ankle Sprains

An ankle replacement is a complex procedure

An ankle replacement is a complex procedure where the joint is replaced by metal and plastic parts. Because it is a very delicate operation, only certain patients are good candidates for this. An ankle replacement is not intended for heavy use or impact activity, so is more commonly recommended in an older and more sedentary population. Revision surgery is commonly required in 10-20 years.

I recently broke my foot and was referred to Dr. Dixon. I got an appointment very quickly. The facility is great. All of the staff that I met from the front desk, to the imaging technician, to Ryann her assistant and of course Dr. Dixon were amazing. On time, professional and simply nice people. My appointment with Dr. Dixon was thorough, very clear on the diagnosis and follow up. I highly recommend.

I went to DR.Dixon for enormous pain in my foot . She was immediately able to isolate the problem and was incredibly knowledgeable, and kind I was so impressed with her demeanor as well,especially in today’s health care world, its amazing to find a DR. who takes the time to make sure you understand the diagnosis and the options for treatment. My foot is doing so much better! I highly recommend this great DR.
