ICD-10: M71.16

Infective bursitis, particularly in the knee, is a condition characterized by inflammation of the bursa due to infection. The ICD-10 code M71.16 specifically refers to "Other infective bursitis, knee." Understanding the standard treatment approaches for this condition is crucial for effective management and recovery.

Overview of Infective Bursitis

Infective bursitis occurs when a bursa, a small fluid-filled sac that reduces friction between tissues, becomes inflamed due to infection. This can result from direct trauma, overuse, or the introduction of pathogens through breaks in the skin. Common symptoms include swelling, pain, redness, and warmth around the affected area.

Standard Treatment Approaches

1. Initial Assessment and Diagnosis

Before treatment can begin, a thorough assessment is necessary. This typically includes:

• Medical History: Understanding the patient's symptoms, duration, and any previous injuries or infections.
• Physical Examination: Checking for swelling, tenderness, and range of motion in the knee.
• Imaging Studies: X-rays or MRI may be used to rule out other conditions and assess the extent of the bursitis.
• Laboratory Tests: Blood tests or aspiration of the bursa fluid can help identify the causative organism and determine the appropriate antibiotic treatment.

2. Antibiotic Therapy

If the bursitis is confirmed to be infectious, antibiotic therapy is the cornerstone of treatment. The choice of antibiotics may depend on the suspected or confirmed pathogen:

• Empirical Antibiotics: Broad-spectrum antibiotics may be initiated while awaiting culture results.
• Targeted Therapy: Once the specific bacteria are identified, treatment can be adjusted to target the organism effectively.

3. Pain Management

Managing pain and inflammation is essential for patient comfort and recovery. Common approaches include:

• Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): Medications such as ibuprofen or naproxen can help reduce pain and swelling.
• Corticosteroids: In some cases, corticosteroid injections may be administered to decrease inflammation.

4. Rest and Activity Modification

Resting the affected knee is crucial to allow healing. Patients are often advised to:

• Limit Weight Bearing: Using crutches or a knee brace can help reduce stress on the joint.
• Modify Activities: Avoiding activities that exacerbate symptoms is important during recovery.

5. Physical Therapy

Once the acute infection is under control, physical therapy may be recommended to restore strength and range of motion. This can include:

• Stretching Exercises: To improve flexibility.
• Strengthening Exercises: To support the knee joint and prevent future injuries.

6. Surgical Intervention

In severe cases, or if there is an abscess formation, surgical intervention may be necessary. This can involve:

• Drainage of the Bursa: To remove infected fluid and relieve pressure.
• Debridement: In cases of extensive infection, surgical cleaning of the bursa may be required.

Conclusion

The management of infective bursitis in the knee, as indicated by ICD-10 code M71.16, involves a comprehensive approach that includes accurate diagnosis, antibiotic therapy, pain management, rest, and possibly physical therapy or surgical intervention.

ICD-10 code M71.16 refers to "Other infective bursitis, knee," which is a specific classification within the International Classification of Diseases, 10th Revision (ICD-10). This code is used to identify cases of bursitis in the knee joint that are caused by infectious agents, distinguishing it from other types of bursitis that may be due to non-infectious causes.

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. When a bursa becomes inflamed, it can lead to pain, swelling, and restricted movement.

Infective Bursitis

Infective bursitis occurs when a bursa becomes infected, often due to bacteria, but it can also be caused by fungi or viruses. The infection can arise from direct trauma, such as a puncture wound, or from the spread of infection from nearby tissues. Common symptoms include:

• Localized Pain: Pain in the affected area, which may worsen with movement.
• Swelling: Noticeable swelling around the knee joint.
• Redness and Warmth: The skin over the bursa may appear red and feel warm to the touch.
• Limited Range of Motion: Difficulty in moving the knee due to pain and swelling.
• Systemic Symptoms: In some cases, fever and malaise may occur if the infection is systemic.

Common Causes

The most common infectious agents responsible for bursitis include:

• Staphylococcus aureus: A common bacterium that can cause skin infections and is often implicated in bursitis.
• Streptococcus species: Another group of bacteria that can lead to infections in soft tissues.
• Other pathogens: In some cases, other bacteria, fungi, or viruses may be involved, particularly in immunocompromised individuals.

Diagnosis and Treatment

Diagnosis

Diagnosis of infective bursitis typically involves:

• Clinical Examination: Assessment of symptoms and physical examination of the knee.
• Imaging Studies: X-rays or ultrasound may be used to evaluate the joint and surrounding tissues.
• Laboratory Tests: Aspiration of bursal fluid may be performed to analyze for the presence of infection and identify the causative organism.

Treatment

Treatment for infective bursitis generally includes:

• Antibiotics: If a bacterial infection is confirmed, appropriate antibiotics are prescribed.
• Rest and Immobilization: Reducing movement of the knee to allow healing.
• Ice Therapy: Application of ice to reduce swelling and pain.
