Clinical Description

Definition of Bursitis

Bursitis is the inflammation of a bursa, which is a small, fluid-filled sac that acts as a cushion between bones and soft tissues, such as muscles, tendons, and skin. Bursae help reduce friction and allow for smooth movement of joints. Infective bursitis occurs when a bursa becomes infected, often due to bacteria, leading to inflammation, pain, and swelling.

Specifics of M71.162

• Location: The code specifically pertains to the left knee, indicating that the infection is localized to the bursa in this joint.
• Infective Nature: The term "other infective" suggests that the bursitis may not be due to the most common pathogens (like Staphylococcus aureus) but could involve other infectious agents or atypical presentations.
• Symptoms: Patients with infective bursitis typically present with localized pain, swelling, warmth, and tenderness around the affected knee. There may also be limited range of motion due to discomfort.

Etiology

Infective bursitis can arise from:
- Direct Infection: Bacteria can enter the bursa through a puncture wound, surgical incision, or skin infection.
- Hematogenous Spread: Infections from other body parts can spread through the bloodstream to the bursa.
- Chronic Conditions: Conditions such as rheumatoid arthritis or gout can predispose individuals to bursitis, including infectious types.

Diagnosis

Diagnosis of M71.162 involves:
- Clinical Examination: Assessment of symptoms and physical examination of the knee.
- Imaging Studies: Ultrasound or MRI may be used to visualize the bursa and assess for fluid accumulation or other abnormalities.
- Laboratory Tests: Aspiration of bursal fluid may be performed to identify the causative organism and guide treatment.

Treatment

Management of infective bursitis typically includes:
- Antibiotics: If a bacterial infection is confirmed, appropriate antibiotic therapy is initiated.
- Rest and Ice: Reducing activity and applying ice can help alleviate symptoms.
- Aspiration: In some cases, draining the infected bursa may be necessary to relieve pressure and remove infected material.
- Surgery: Rarely, surgical intervention may be required if there is an abscess or if conservative treatments fail.

The diagnosis of ICD-10 code M71.162, which refers to "Other infective bursitis, left knee," involves specific clinical criteria and considerations. Here’s a detailed overview of the diagnostic criteria and relevant information regarding this condition.

Understanding Infective Bursitis

Bursitis is the inflammation of a bursa, a small fluid-filled sac that acts as a cushion between bones and soft tissues. Infective bursitis occurs when a bursa becomes infected, often leading to pain, swelling, and limited mobility in the affected area. The left knee is a common site for this condition due to its anatomical structure and the stress it endures during movement.

Diagnostic Criteria

Clinical Evaluation

1. History Taking:
   - The clinician will gather a detailed medical history, including any recent injuries, infections, or underlying health conditions (e.g., diabetes, rheumatoid arthritis) that may predispose the patient to infections.

2. Physical Examination:
   - The examination will focus on the left knee, assessing for signs of inflammation such as swelling, redness, warmth, and tenderness over the bursa. The range of motion may also be evaluated to determine any limitations.

Laboratory Tests

1. Aspiration and Analysis:
   - A key diagnostic procedure is the aspiration of the bursa fluid. This involves using a needle to withdraw fluid from the bursa, which can then be analyzed for:

   • Presence of Infection: The fluid is examined for bacteria, white blood cells, and other indicators of infection.
   • Culture Tests: Culturing the fluid can help identify the specific pathogen responsible for the infection, guiding appropriate antibiotic therapy.

2. Blood Tests:
   - Blood tests may be conducted to check for signs of systemic infection, such as elevated white blood cell counts or inflammatory markers (e.g., C-reactive protein).

Imaging Studies

1. Ultrasound or MRI:
   - Imaging studies may be utilized to visualize the bursa and surrounding tissues. These can help confirm the diagnosis by showing fluid accumulation or other abnormalities in the knee joint.

Differential Diagnosis

It is essential to differentiate infective bursitis from other conditions that may present similarly, such as:

• Non-infective bursitis: Caused by repetitive motion or trauma without infection.
• Septic arthritis: An infection within the joint itself, which may require different management.
• Gout or pseudogout: Crystal-induced arthritis that can mimic bursitis symptoms.

Conclusion

The diagnosis of ICD-10 code M71.162 for other infective bursitis of the left knee is based on a combination of clinical evaluation, laboratory tests, and imaging studies. Accurate diagnosis is crucial for effective treatment, which may include antibiotics for infection and possibly surgical intervention if there is an abscess or persistent fluid collection. If you suspect infective bursitis, it is important to seek medical attention for a thorough evaluation and appropriate management.
