Nonsteroidal anti-inflammatory drugs (NSAIDs) are often prescribed to manage pain and inflammation associated with arthritis. Common NSAIDs include:

• Ibuprofen
• Naproxen

In some cases, corticosteroids may be administered either orally or via injection to reduce inflammation, especially if NSAIDs are insufficient.

4. Physical Therapy

Once the acute infection is under control, physical therapy may be recommended to restore function and strength to the affected joint. This can include:

• Range-of-motion exercises
• Strengthening exercises
• Gait training

5. Surgical Intervention

In severe cases, particularly if there is joint destruction or persistent infection, surgical intervention may be necessary. This could involve:

• Debridement of infected tissue
• Joint replacement in cases of significant damage

6. Monitoring and Follow-Up

Regular follow-up is crucial to monitor the response to treatment and to adjust the therapeutic approach as needed. This may include repeat imaging studies or laboratory tests to ensure the infection is resolving.

Conclusion

The management of arthritis due to other bacteria (ICD-10 code M00.879) involves a multifaceted approach that includes antibiotic therapy, joint aspiration, anti-inflammatory medications, physical therapy, and possibly surgical intervention. Early diagnosis and treatment are essential to prevent long-term joint damage and to improve patient outcomes.
