Understanding Subpeduncular Bursitis: Causes, Symptoms, and Treatment Options

A subpeduncle is a small, bony projection that can be found on the underside of the peduncle (the bony structure that connects the femur to the tibia in the knee joint). The subpeduncle is located just below the kneecap and is visible as a small bump on the inside of the knee.

The subpeduncle is a normal anatomical feature and is present in most people. However, in some cases, it can become inflamed or irritated, leading to pain and discomfort in the knee. This condition is known as subpeduncular bursitis or prepatellar bursitis.

Subpeduncular bursitis can be caused by a variety of factors, including repetitive kneeling or squatting, direct blows to the knee, or underlying conditions such as gout or rheumatoid arthritis. Symptoms of subpeduncular bursitis may include pain and tenderness in the knee, swelling and redness around the bursa, and limited mobility in the knee joint.

Treatment for subpeduncular bursitis typically involves rest, ice, compression, and elevation (RICE) to reduce inflammation and relieve pain. In severe cases, corticosteroid injections or surgical drainage may be necessary to remove excess fluid and promote healing.
