The cornerstone of treatment for streptococcal arthritis is antibiotic therapy. The choice of antibiotic may depend on the specific strain of streptococcus involved, but common options include:

• Penicillin: Often the first-line treatment for streptococcal infections.
• Cephalosporins: These may be used if the patient is allergic to penicillin or if the infection is resistant.
• Clindamycin: This is an alternative for patients with penicillin allergies or for certain resistant strains.

The duration of antibiotic treatment typically ranges from 10 to 14 days, but it may be extended based on clinical response and laboratory findings[1][2].

2. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)

To manage pain and inflammation associated with arthritis, NSAIDs are commonly prescribed. These medications help reduce swelling and alleviate discomfort. Common NSAIDs include:

• Ibuprofen
• Naproxen

In some cases, corticosteroids may be considered for more severe inflammation, but they are generally used with caution due to potential side effects[3][4].

3. Joint Aspiration and Injection

If there is significant swelling or effusion in the knee joint, a procedure known as arthrocentesis (joint aspiration) may be performed. This involves:

• Draining excess fluid: This can relieve pressure and pain.
• Injecting corticosteroids: In some cases, a corticosteroid injection may be administered to reduce inflammation directly within the joint[5].

4. Physical Therapy

Once the acute phase of the infection is managed, physical therapy may be recommended to restore function and strength to the knee. This can include:

• Range of motion exercises: To improve flexibility.
• Strengthening exercises: To support the knee joint and prevent future injuries.

5. Monitoring and Follow-Up

Regular follow-up appointments are crucial to monitor the patient's response to treatment, assess for any complications, and adjust the treatment plan as necessary. This may include repeat imaging studies or laboratory tests to ensure the infection is resolving[6].

Conclusion

The management of Other streptococcal arthritis, unspecified knee (ICD-10 code M00.269) involves a comprehensive approach that includes antibiotic therapy, pain management, potential joint procedures, and rehabilitation. Early diagnosis and treatment are vital to prevent complications and ensure optimal recovery. Patients should be encouraged to maintain open communication with their healthcare providers to address any concerns during their treatment journey.
