Hoffa's Syndrome
(Fat Pad Impingement)

Your Hoffa's pad (infrapatellar fat pad) is a fatty pad that sits below your patella (knee cap) directly behind your patellar tendon. It cushions the patella, preventing it from hitting against the condyle of your femur (or end of the thigh bone) in the case of a direct blow to the front of the knee. The fat pad in the knee has a lot of nerves, so any injury to it is extremely painful.

Hoffa's Syndrome causes pain in the front of the knee with swelling and inflammation under the knee cap and along the patellar tendon.

Hoffa's Syndrome is a condition in which the infrapatellar fat pad either suffers a contusion or an injury, resulting in damage and swelling. This can lead to the Hoffa's pad becoming trapped between the femur and the patella every time the leg is extended.

Fat pad impingement can also occur if the fat pad is pinched when the leg turns inward abnormally while running. The risk of this happening increases if you have instability in your knees or hips which can be a result of other conditions such as Achilles injuries. When favouring a sore Achilles tendon in one foot, you begin to use improper mechanics to walk or run and this can lead to unbalanced loads and over straining one of your knees and/or hips.

Because straightening the leg will cause the fat pad to become trapped, it is being re-injured constantly and can lead to a significant recovery time if not treated quickly and correctly.


Hoffa's Syndrome Causes

Hoffa's Syndrome (fat pad impingement) can be caused by the fat pad pinching between the patella (knee cap) and the femur following a blow during contact sports.
  • People participating in activities or sports where a blow to the knee is possible such as football, rugby, soccer, and hockey.
  • If you have suffered an anterior cruciate ligament (ACL) injury the stability of your knee decreases leaving the infrapatellar fat pad more prone to being pinched.
  • Runners with excessive pronation (also known as flat feet) or weak hips may experience quick leg turns inward while the knee cap (patella) remains behind, causing the fat pad to be pinched.
  • People who have Iliotibial (IT) Band Syndrome.
  • Anyone who has a history of hyperextension in the knee

Fat Pad Impingement Symptoms

  • Pain, inflammation, and swelling at the front of the knee cap and along the sides of the patellar tendon.
  • Increased pain when the knee is extended.
  • Standing for long periods on hyperextended knees will increase the pain.
  • Squatting or using stairs will often make the pain worse.

Hoffa's Syndrome Test

Your doctor or health care professional will examine your knee to determine if you have Hoffa's Syndrome (fat pad impingement). He/she will ask you to lie down with a bent knee. You then slowly straighten your leg while the doctor presses his or her fingers below the knee cap (patella), on either side of the patellar tendon. Any pain or hesitation when straightening the leg is considered a positive test for Hoffa's Syndrome.


Treating Knee Pain - What You Can Do!

Allowing your knee to rest is always recommended when you are suffering from fat pad impingement. Avoid activities that may have caused the injury or irritation and begin cold compression treatments as soon as possible. It is difficult to rest your knee completely as you have to get on with your daily activities.

Fortunately, there are tools that can help treat your pinched fat pad and speed up the healing process so you can get back to a life without pain and risk of further injury. The TShellz® Circulatory Boost Wrap is intended to promote blood flow and flexibility to soft tissue in the knee. This in turn, boosts your bodys natural healing mechanism, allowing your knee to heal knee faster and more completely than any other home treatment methods that we know of. Circulatory Boost is best achieved through use of the TShellz Wrap®.

Cold Therapy

Using a Cold Compress or Ice Pack immediately following an injury reduces pain, swelling, and tissue damage that occurs when you have Hoffa's Syndrome (fat pad impingement). Cold Compression works by interrupting and slowing nerve and tissue function in damaged soft tissue. This is important because once blood vessels are damaged, they can no longer carry oxygenated blood to the infrapatellar fat pad and patella tendon and tissues begin to break-down.

Circulation Boost

Knee Wrap speeds healing soft tissue patella Hoffa's Syndrome.

After the inflammation and swelling behind your knee cap and around your patellar tendon is gone, you can begin to treat your entire knee with Circulation Boost via the Knee TShellz Wrap®. A knee TShellz Wrap® treatment increases the amount of blood that flows naturally to soft tissue in the knee.

Circulatory Boost (via use of the Knee TShellz Wrap®) compliments your body's natural healing process by promoting blood flow while you give your knee the rest it needs. Energy emitted from the Energy Pad stimulates blood flow to your knee, more than your body would ever be able to generate on it's own, giving your body the boost it needs to continue the reconditioning process. This enhanced blood flow helps speed tissue repair, whisk away toxins and dead tissue, and rejuvenates soft tissue for improved elasticity.
