M76.40
Tibial collateral bursitis [Pellegrini-Stieda], unspecified leg
Clinical Classification Guidelines
Medical Intelligence & Overview
Tibial collateral bursitis, associated with the Pellegrini-Stieda lesion, is an inflammation of the bursa located near the medial collateral ligament (MCL) of the knee. The condition can cause pain, swelling, and sometimes stiffness in the affected area, often related to injury or overuse. While often linked to traumatic events, it can also develop gradually due to repetitive stress on the knee joint, especially in athletes or individuals involved in activities that put strain on the knee.
Causes & Symptoms
Clinical Causes: Trauma or direct injury to the knee, such as falls, blows, or sports injuries Repetitive stress or overuse of the knee joint, common in athletes and those engaged in vigorous activities Chronic MCL strain leading to inflammation around the medial knee Degenerative changes in the knee joint Previous knee surgeries or interventions that alter the normal anatomy
Key Symptoms: Pain localized on the inner (medial) side of the knee Swelling or tenderness around the medial collateral ligament area Limited range of motion or stiffness in the knee A feeling of instability or weakness in the joint Possible visible or palpable swelling over the affected bursa Discomfort that worsens with activity and improves with rest
Diagnostic & Treatment
Diagnosis Path: X-rays can reveal calcifications or lesions associated with Pellegrini-Stieda Magnetic Resonance Imaging (MRI) provides detailed images of the soft tissues, including the bursae and ligament structures, helping to identify inflammation or fluid buildup Ultrasound examinations can also be useful for detecting bursitis and guiding aspiration if needed
Treatment Protocols: Rest and activity modification to prevent further irritation Ice application to reduce swelling and pain Nonsteroidal anti-inflammatory drugs (NSAIDs) to control inflammation and discomfort Physical therapy to strengthen muscles around the knee and improve joint stability In some cases, corticosteroid injections may be administered for more significant inflammation Aspiration of the bursa fluid if there is significant swelling or fluid accumulation Surgical intervention is rarely needed but may be considered in persistent or complicated cases
