M70.4

Clinical Causes: Repeated kneeling or pressure on the knee, often seen in occupations or activities that involve frequent contact with the ground Trauma or direct injury to the front of the knee, such as a blow or fall Infections that spread to the bursa, leading to bursitis Chronic conditions like gout or rheumatoid arthritis Degenerative changes associated with aging or overuse Using the knee as a leverage point for lifting or leaning

Key Symptoms: Swelling in front of the kneecap that may appear gradually or suddenly Tenderness over the bursa area upon touch Pain that worsens with movement or pressure Warmth and redness over the affected area in some cases Limited ability to fully bend or straighten the knee A feeling of stiffness or heaviness in the knee

Diagnosis Path: Diagnosis of prepatellar bursitis generally involves a physical examination, where a healthcare provider assesses swelling, tenderness, and range of motion. They may inquire about recent activities that could have caused irritation. To confirm the diagnosis and rule out other causes, diagnostic procedures like ultrasound imaging or aspiration of the bursa fluid may be performed. Laboratory analysis of the fluid can determine if infection or other underlying conditions are contributing to the bursitis.

Treatment Protocols: Treatment focuses on relieving symptoms and addressing underlying causes. Common approaches include: - Rest and avoiding activities that exacerbate the condition - Applying ice packs to reduce swelling and pain - Nonsteroidal anti-inflammatory drugs (NSAIDs) to alleviate discomfort and inflammation - Elevating the affected leg to decrease swelling - Using a knee pad or cushioning to avoid pressure on the bursa - In some cases, aspiration of excess fluid may be performed to relieve pressure - Antibiotics if an infection is present - Physical therapy to strengthen surrounding muscles and improve knee function - In persistent or severe cases, corticosteroid injections may be considered - Surgical intervention is rarely needed but may be necessary if bursitis recurs or does not respond to conservative treatment Preventive measures include wearing protective padding during activities that involve kneeling and maintaining good knee hygiene to minimize the risk of infection.
