Fat pad syndrome
Author: Raphael Fung, Registered Physiotherapist
Also known as Hoffa's syndrome, this refers to the compression or inflammation of the fat pad in the knee joint area, leading to pain and discomfort. The fat pad is elastic fatty tissue located below the patella (kneecap) and in the tibial space, which absorbs impact and protects the knee joint. When this area is irritated or injured, fat pad syndrome can develop.
The causes of fat pad syndrome may include:
- Direct Impact:
A direct impact to the knee, such as falling or hitting a hard object during exercise, can injure the fat pad. - Overuse:
Prolonged or repetitive activities, such as long-distance running and jumping, can cause excessive compression of the fat pad at the front of the knee. - Biomechanical Problems:
Abnormal knee alignment, such as an abnormal patellar position, can increase pressure on the fat pad. - Obesity:
Excess weight increases the load on the knee joint, which can lead to additional compression of the fat pad. - Knee Joint Inflammation:
Other inflammatory conditions of the knee joint, such as arthritis, can lead to inflammation around the fat pad. - Poor Posture:
Maintaining poor standing or sitting posture for extended periods can increase pressure on the knee fat pad. - Post-Surgical Effects:
After knee surgery, such as arthroscopy, the position or health of the fat pad may be affected. - Degenerative Changes:
As we age, the fat pad may degenerate, making it more susceptible to injury.
Symptoms of fat pad syndrome typically include pain around the knee, especially exacerbated after activities such as standing, walking, or running. The pain may be strongest at the front or inner side of the knee. Treatment usually involves reducing activity to relieve pressure, physical therapy, anti-inflammatory medications, and possibly injection therapy. In some cases, if non-surgical treatments are ineffective, surgery may be required.
