Osteoarthritis of the ankle occurs when the cartilage between the bones begins to wear down. This can cause stiffness, swelling, and pain in the joints, making it difficult to walk.
Diagnosis involves a physical exam, gait analysis, x-rays, and blood tests. After the diagnosis, doctors may recommend weight loss, exercise, and a change in activities to reduce or manage symptoms.
If treatment is required, the
This article discusses the symptoms, diagnosis, and outlook for people with osteoarthritis of the ankle. He also explores the exercises and the treatment of the disease.
In a healthy ankle, cartilage covers the bone surfaces that meet, serving as protective padding.
In osteoarthritis of the ankle, this protective space slowly decreases because the cartilage gradually wears down. As a result, the bones rub against each other, leading to the formation of painful bone spurs.
Osteoarthritis of the ankle affects about 1% of the population.
Symptoms worsen over time and include:
- stiffness and pain that gets worse in the morning
- swelling on one side or all around the joint
- reduced range of motion, which means the joint cannot fully bend
- tenderness to touch or squeeze the joint
- difficulty walking
According to the Arthritis Foundation (AF), treatment includes non-drug measures, medication, and surgery.
Non-drug treatment recommendations include:
Drug treatments include drugs in the form of:
The pills include acetaminophen (Tylenol) for pain relief or nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil), for pain and inflammation relief.
Acetaminophen is the
Creams or gels may include those that contain any of the following ingredients:
The injections involve glucocorticoids, such as betamethasone (Celestone Soluspan). They provide short-term pain relief, and doctors only give them to a person three or four times a year.
When other treatments don’t manage pain or improve mobility, doctors may recommend one of the following surgeries:
- Arthrodesis: This fuses the ankle bones together.
- Arthroscopic surgery: This involves the removal of bone spurs and loose cartilage, which can help some people. Doctors rarely use it for osteoarthritis.
- Total ankle replacement: This involves removing the bones and cartilage and replacing them with plastic or metal parts.
Full recovery from surgery may take 4 to 9 months, but most people can return to their regular activities within 3 to 4 months.
Experts recommend gentle exercises that don’t strain the ankle, such as:
They also advise avoiding certain sports, such as kickboxing and soccer, and limiting high-impact activities, such as running or tennis.
Additionally, physiotherapists may provide an individualized exercise program to increase range of motion, flexibility, and ankle strength.
A person can also do range of motion exercises at home. They should do them slowly, aiming for a slight stretch. People shouldn’t overdo it or go past the pain point. It is best to consult a doctor before starting new exercises.
As a rule of thumb, experts recommend doing range of motion exercises 3-10 times a day. A person should sit while doing these exercises and maintain good posture with the feet on the floor. Below are a few options:
- Plantar flexion: Push your toes down and lift your heels off the ground as if you were stepping on an accelerator pedal.
- Dorsiflexion: Raise your toes towards the shins. Do this more slowly, but try to place the toes as high as possible while keeping the heels on the floor.
- Ankle circles: Slowly move the pegs in a circle, as if you were trying to write the letter “O”. Make the two circles clockwise and counterclockwise.
The American Academy of Orthopedic Surgeons (AAOS) provides details on the diagnostic process below.
During a physical exam, a doctor will look for swelling and tenderness and ask the following questions:
- When did the pain start?
- Have you had an injury in the past?
- The pain comes and goes or is it continuous?
- Where exactly is the pain?
- Is the pain worse in the morning or does it get worse with walking?
Doctors ask people to walk to see if their gait reveals any of the effects of osteoarthritis. For example, stiffness and pain can cause lameness, showing the location and severity of the disease.
Gait analysis also includes:
- stride measurement
- assessment of bone alignment while walking
- ankle and foot strength test
Tests can include x-rays, which can reveal a narrowing of the joint space between the ankle bones, as well as spurs and other changes, such as fractures or breaks. Additionally, doctors may order blood tests to rule out other types of arthritis.
Musculoskeletal ultrasound can also be useful, particularly for the detection of tendon injury or inflammation.
The AF notes that it is not possible to cure or reverse osteoarthritis, but treatment can reduce pain and allow a person to carry out daily activities.
Medical resources paint a slightly different picture of the outlook after surgery. AAOS says that in most cases it reduces pain and allows people to function.
Experts advise people with the condition to engage in a program of physical therapy or gentle exercise, such as walking or swimming. If the disease progresses, medications can help manage the pain. Surgery is the
