Hoffa’s Disease

Causes, Symptoms, and Treatment of Knee Fat Pad Impingement

Knee fat pad impingement, also called Hoffa’s Disease or infrapatellar fat pad hypertrophy, occurs when the fat pad beneath the kneecap becomes irritated and enlarged. This often develops from repetitive trauma, overuse, or direct injury to the knee.

 

Symptoms may include chronic knee pain, tenderness, swelling, and limited range of motion. The enlarged fat pad can also compress nearby structures, worsening discomfort.

 

Diagnosis is usually made with a physical examination and imaging studies, while ruling out other potential causes of knee pain.

 

Treatment often begins with conservative measures such as rest, ice, anti-inflammatory medication, and activity modification. Corticosteroid injections may be used for persistent symptoms. In severe cases, surgery may be needed to remove part of the fat pad and relieve impingement.

 

Early medical care and a structured treatment plan can help reduce symptoms and restore knee function.
