Ankle Arthritis

Ankle arthritis involves the degeneration of cartilage in the ankle joint, leading to pain, stiffness, and reduced mobility. It can result from wear and tear, previous injuries, or inflammatory diseases. Common treatments include physical therapy, medication, and in severe cases, surgery.

What is Ankle Pain?

Ankle pain associated with arthritis often worsens with activity and improves with rest. Symptoms may include swelling, stiffness, and a decreased range of motion, particularly after periods of inactivity or at the end of the day. Ankle pain is a common issue that affects people of all ages and can significantly impact mobility and quality of life. Understanding the causes and symptoms of ankle pain is essential for seeking appropriate medical attention and managing the condition effectively.

The most common causes of ankle arthritis include:

• Osteoarthritis (OA): Wear and tear on the joint cartilage over time, leading to bone-on-bone contact and pain.

• Rheumatoid Arthritis (RA): Chronic inflammation in the joints, causing pain, stiffness, and swelling.

• Gout: Excess uric acid in the bloodstream, leading to sudden, severe joint pain and swelling.

• Ankle Sprains: Injuries to the ligaments, which can lead to chronic instability and arthritis.

• Other Causes: Include trauma (like accidents) infections, fractures, tendonitis (such as Achilles tendonitis), and bursitis.

Understanding these causes can help in identifying the underlying factors contributing to ankle pain and arthritis, which is crucial for developing an effective treatment plan.

Several factors can increase the likelihood of developing ankle arthritis, leading to symptoms such as ankle pain.

• Age: The risk of developing ankle arthritis increases with age due to cumulative wear and tear on the joints.

• Previous Injuries: Past trauma to the ankle, such as fractures, dislocations, or chronic ligament injuries, significantly raises the likelihood of arthritis.

• Obesity: Excess weight adds stress to the ankle joints, making them more susceptible to arthritis.

• Family History: A genetic predisposition can increase the risk, particularly if there is a family history of arthritis.

• Metabolic Diseases: Conditions like diabetes can elevate the risk of developing ankle arthritis.

• Architectural Abnormalities: Structural issues with the foot can contribute to the development of arthritis.

• Intense Physical Exercise: Activities that impose repetitive stress on the ankle joint can lead to arthritis over time.

• Smoking: Tobacco use may worsen arthritis symptoms and increase susceptibility.

• Infections: Certain infections, including Lyme disease and Staphylococcus infections, can heighten the risk of developing ankle arthritis.

While some risk factors for ankle arthritis may be beyond an individual's control, there are several preventive measures that can help reduce the likelihood of developing the condition or alleviate symptoms such as heel and ankle pain.

• Maintaining a healthy weight is crucial, as it can minimise the stress placed on the joints and lower the risk of arthritis on the ankle.

• Staying active and engaging in regular exercise can help maintain joint mobility and reduce the risk of ankle arthritis. However, it is essential to avoid joint injuries by wearing protective gear and using proper techniques during physical activities.

• Managing chronic conditions like diabetes and metabolic disorders effectively can also help reduce the risk of developing ankle arthritis.

• Quitting smoking can lower the risk of developing rheumatoid arthritis and prevent the worsening of arthritis symptoms.

By implementing these preventive strategies, individuals can take proactive steps to maintain the health of their ankle joints and reduce the likelihood of experiencing debilitating ankle pain when walking or engaging in daily activities.

A healthcare provider will conduct a thorough assessment of your ankle pain, which may include a physical examination, X-rays, and possibly additional imaging like CT scans, MRI scans, or ultrasounds.

Although ankle arthritis cannot be cured, several treatment strategies are available to manage pain, improve mobility, reduce further joint deterioration and preserve joint function. Management may involve a combination of non-surgical therapies, lifestyle changes, medications, and, if necessary, surgery. Here are the treatment option:

Non-Surgical Treatment Options

1. Lifestyle Modifications
Modifying daily activities can significantly reduce pain and slow the progression of arthritis in the ankle joint. Key recommendations may include:

• Avoiding activities that worsen the condition, such as prolonged standing, walking on uneven surfaces, or high-impact sports.
• Replacing high-impact exercises (e.g. running or tennis) with low-impact alternatives such as swimming, stationary cycling, or water aerobics.
• Weight reduction, if necessary, to decrease stress on the ankle joint and improve overall joint function.

2. Physical Therapy
A tailored physiotherapy programme may help to:

• Increase joint range of motion and flexibility.
• Strengthen the muscles supporting the ankle, improving joint stability and function.

However, in some cases, physical activity may exacerbate joint pain due to increased friction in the arthritic joint. If pain worsens, your provider may advise discontinuing or adjusting the therapy.

3. Bracing and Supportive Devices
A custom-moulded leather brace or ankle-foot orthosis (AFO) may be recommended to offload the joint and improve mobility.

• Shoe modifications, such as orthotic inserts, rocker-bottom soles, or custom-made footwear, can also help redistribute pressure away from affected joints.
  
   
• In cases of deformity, specific orthoses may help align the foot and ankle, easing discomfort during walking or standing.

Medications for Ankle Arthritis

Several medications can be used to manage ankle arthritis symptoms:

Nonsteroidal anti-inflammatory drugs (NSAIDs) 

These are commonly used to reduce inflammation and relieve pain.

• Ibuprofen: A widely used over-the-counter NSAID that provides effective short-term relief from pain and swelling.
• Naproxen: Offers longer-lasting pain relief and is particularly helpful for managing chronic inflammation in arthritis.

Corticosteroid injections 

A steroid injection (e.g. triamcinolone or methylprednisolone) combined with a local anaesthetic (such as lidocaine or bupivacaine) is administered directly into the joint to reduce inflammation and provide temporary relief.

• Triamcinolone: A potent steroid that helps reduce joint swelling and pain for several weeks to months.
• Methylprednisolone: Commonly used for quick symptom control in moderate to severe flare-ups.

These steroids are usually combined with local anaesthetics such as:

• Lidocaine: Provides immediate numbing of the joint area for comfort during and after the injection.
• Bupivacaine: Offers longer-lasting local pain relief following the procedure.

It is important to note that the effects of corticosteroid injections are typically short-term and should not be repeated frequently due to the risk of cartilage damage.

Surgeries

Surgery may be considered if non-surgical measures fail to relieve pain and restore function. The choice of procedure depends on the severity of joint damage and overall joint health.

• Arthroscopic Debridement: A minimally invasive technique where damaged cartilage, bone spurs, or inflamed tissue are removed using a small camera and surgical tools.
• Arthrodesis (Joint Fusion): This involves fusing the bones of the ankle joint to eliminate movement and prevent pain. It is highly effective for severe arthritis but results in a loss of ankle flexibility.
• Total Ankle Replacement (Ankle Arthroplasty): The damaged joint is replaced with a prosthetic implant, preserving joint motion. This is generally reserved for patients with advanced arthritis who wish to maintain joint mobility.

If you are experiencing persistent ankle pain, swelling, or stiffness, it is crucial to consult a doctor for a proper diagnosis and treatment plan. Ignoring these symptoms can lead to further damage and potentially worsen your condition. Here are some key scenarios that warrant medical attention:

• Ankle pain that persists for more than a few weeks or worsens over time

• Swelling in the legs and feet that does not improve with rest or elevation

• Difficulty walking or bearing weight on the affected ankle

• Heel and ankle pain that is severe or accompanied by redness and warmth

• Ankle pain that is accompanied by fever, chills, or other signs of infection

Your doctor will conduct a thorough examination, which may include imaging tests such as X-rays or MRI scans, to determine the cause of your ankle pain and the extent of any damage. Based on the diagnosis, they will develop a personalised treatment plan to manage your symptoms and prevent further progression of ankle arthritis.
