M76.4
Tibial collateral bursitis [Pellegrini-Stieda]
Clinical Classification Guidelines
Medical Intelligence & Overview
Tibial collateral bursitis, also known as Pellegrini-Stieda syndrome, is an inflammation of the bursa located near the tibial collateral ligament of the knee. This condition leads to pain, swelling, and discomfort around the inner side of the knee, affecting mobility and daily activities. It typically results from trauma or repetitive stress, causing irritation of the bursa, a small fluid-filled sac designed to reduce friction during joint movement.
Causes & Symptoms
Clinical Causes: Direct injury or trauma to the inside of the knee Repetitive knee movements or overuse, especially in athletes Knee instability or ligament injuries Pre-existing knee conditions, such as osteoarthritis Infections or bacterial invasion of the bursa (less common)
Key Symptoms: Localized pain on the inner side of the knee Swelling and tenderness around the tibial collateral area Stiffness and decreased range of motion in the knee joint Warmth or redness indicating inflammation Pain aggravated by activities involving knee bending or weight-bearing
Diagnostic & Treatment
Diagnosis Path: Diagnosis of tibial collateral bursitis involves a thorough clinical examination, focusing on knee swelling and tenderness. Imaging studies like X-rays can help identify associated bony changes such as Pellegrini-Stieda phenomenon, where calcification occurs at the ligament's origin. Ultrasound may be used to assess the bursa’s inflammation, and MRI can provide detailed images of soft tissue involvement. A healthcare professional may also consider joint fluid analysis if an infection is suspected.
Treatment Protocols: Management typically includes strategies aimed at reducing inflammation and relieving symptoms. Approaches may involve:
