Rheumatoid arthritis (RA) is a chronic inflammatory disorder that primarily affects joints, including those in the ankle and foot. The ICD-10 code M05.87 specifically refers to "Other rheumatoid arthritis with rheumatoid factor" affecting the ankle and foot. Treatment for this condition typically involves a combination of pharmacological and non-pharmacological approaches aimed at managing symptoms, reducing inflammation, and improving joint function.

Pharmacological Treatments

1. Disease-Modifying Antirheumatic Drugs (DMARDs)

DMARDs are essential in the management of rheumatoid arthritis as they help slow disease progression and prevent joint damage. Common DMARDs include:
- Methotrexate: Often the first-line treatment, it helps reduce inflammation and prevent joint damage.
- Leflunomide: An alternative to methotrexate, it also works to inhibit the immune response.
- Sulfasalazine: This medication can be effective for patients with mild to moderate RA.

2. Biologic Agents

For patients who do not respond adequately to traditional DMARDs, biologic agents may be prescribed. These include:
- Tumor Necrosis Factor (TNF) Inhibitors: Such as Infliximab (Remicade), Etanercept (Enbrel), and Adalimumab (Humira), which target specific components of the immune system.
- Interleukin-6 (IL-6) Inhibitors: Such as Tocilizumab (Actemra), which can help reduce inflammation.
- B-cell Depleting Agents: Like Rituximab (Rituxan), which target B-cells involved in the autoimmune response.

3. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)

NSAIDs are commonly used to relieve pain and reduce inflammation. Over-the-counter options include ibuprofen and naproxen, while prescription options may include stronger formulations.

4. Corticosteroids

Corticosteroids, such as prednisone, can be used for short-term management of severe inflammation and flare-ups. They are effective but are generally not recommended for long-term use due to potential side effects.

Non-Pharmacological Treatments

1. Physical Therapy

Physical therapy plays a crucial role in maintaining joint function and mobility. A physical therapist can design a personalized exercise program that focuses on:
- Strengthening: Building muscle strength around affected joints.
