Fat Pad Syndrome
Fat Pad Syndrome
Fat Pad Impingement, Hoffa’s Syndrome
What is Your Hoffa’s Fat Pad?
Hoffa’s fat pad is your knee fat pad, or infrapatellar fat pad is a soft tissue structure that lies just below and under the patella tendon. The fat pad has abundant nerve innervation, making it one of the most pain-sensitive knee structures.
If irritated, your fat pad can be a great source of knee pain and discomfort. Since the fat sits just below the knee cap, it can cause pinching or “impingement” on the fat pad if there are problems with the kneecap alignment. Fat pad syndrome is also known as Hoffa’s Syndrome.
What Causes Fat Pad Syndrome?
- A forceful blow to the front of the knee (i.e. fall, motor vehicle accident, football tackle)
- Tight quadriceps
- Genu recurvatum (excessive extension of the knee)
- Forward tipping pelvis
- History of osteoarthritis in the knee
- Scarring and subsequent fibrosis (hardening) of the fat pad
What are the Symptoms of Fat Pad Syndrome?
Fat Pad Impingement, also called Hoffa’s Syndrome, can include some or all of the following symptoms:
- Pain in the front of the knee
- Swelling below and around the knee
- Pain with fully straightening the knee
- Pain with prolonged walking, squatting and kicking activities.
- Pain with wearing high heels
These symptoms can also be characteristic of several other knee conditions. e.g. patellar tendinopathy or patellofemoral joint pain syndrome. Hence, it is best to contact your knee physiotherapist for a thorough assessment and proper diagnosis.
How is Fat Pad Syndrome Diagnosed?
On examination, your physiotherapist or sports doctor will look for signs of the symptoms mentioned above. Also, they will perform a clinical test called Hoffa’s test, which involves moving the kneecap after you contract your quadriceps muscles.
An MRI may also diagnose fat pad inflammation, but it is not very accurate for diagnosing fat pad impingement. A thorough assessment by your physiotherapist or sports doctor is usually able to provide you with a more definitive movement associated diagnosis.
Please seek the advice of your physiotherapist.
What is the Treatment for Fat Pad Syndrome?
Physiotherapy treatment will hasten your recovery. Your physiotherapist will aim to:
- Reduce your pain and inflammation. Modalities may include electrotherapy, cryotherapy, therapeutic taping, acupuncture and gait education.
- Normalise your joint and muscle range of motion.
- Strengthen your knee and leg muscles.
- Optimise your patellofemoral (kneecap) alignment.
- Improve your proprioception, agility, dynamic balance, landing technique and function, e.g. walking, running, squatting, hopping and landing.
We suggest that you discuss your knee injury after a thorough examination and accurate diagnosis from your knee injuries clinicians such as your sports physiotherapist, sports doctor or knee surgeon.
If knee pain and symptoms continue to persist, fat pad surgery may be an option. Surgical treatment of fat pad impingement may involve arthroscopic debridement or partial removal of the fat pad.
How to Prevent Fat Pad Syndrome?
The best way to prevent the occurrence or recurrence of fat pad impingement is to optimise the muscles’ strength and flexibility around the knee, hip, and ankle. Your physiotherapist is an expert at guiding you towards the best exercises to correct any deficits in these areas.
If you have previously battled fat pad impingement, it is best to avoid potentially aggravating activities such as kneeling, squatting and kicking for prolonged periods. For females, it is best to limit walking in high heels.
Please seek the advice of your physiotherapist.
Common Causes - Knee Pain
Knee pain can have many origins from local injury, referred pain, biomechanical issues and systemic issues. While knee pain can appear simple to the untrained eye, a thorough assessment is often required to ascertain the origin of your symptoms. The good news is that once a definitive diagnosis is determined, most knee pain quickly resolves with the correct treatment and rehabilitation.

Acute Injury Signs
Acute Injury Management.
Here are some warning signs that you have an injury. While some injuries are immediately evident, others can creep up slowly and progressively get worse. If you don't pay attention to both types of injuries, chronic problems can develop.
For detailed information on specific injuries, check out the injury by body part section.
Don't Ignore these Injury Warning Signs
Joint pain, particularly in the knee, ankle, elbow, and wrist joints, should never be ignored. Because these joints are not covered by muscle, pain here is rarely of muscular origin. Joint pain that lasts more than 48 hours requires a professional diagnosis.
If you can elicit pain at a specific point in a bone, muscle, or joint, you may have a significant injury by pressing your finger into it. If the same spot on the other side of the body does not produce the same pain, you should probably see your health professional.
Nearly all sports or musculoskeletal injuries cause swelling. Swelling is usually quite obvious and can be seen, but occasionally you may feel as though something is swollen or "full" even though it looks normal. Swelling usually goes along with pain, redness and heat.
Reduced Range of Motion
If the swelling isn't obvious, you can usually find it by checking for a reduced range of motion in a joint. If there is significant swelling within a joint, you will lose range of motion. Compare one side of the body with the other to identify major differences. If there are any, you probably have an injury that needs attention.
Compare sides for weakness by performing the same task. One way to tell is to lift the same weight with the right and left sides and look at the result. Or try to place body weight on one leg and then the other. A difference in your ability to support your weight is another suggestion of an injury that requires attention.
Immediate Injury Treatment: Step-by-Step Guidelines
- Stop the activity immediately.
- Wrap the injured part in a compression bandage.
- Apply ice to the injured part (use a bag of crushed ice or a bag of frozen vegetables).
- Elevate the injured part to reduce swelling.
- Consult your health practitioner for a proper diagnosis of any serious injury.
- Rehabilitate your injury under professional guidance.
- Seek a second opinion if you are not improving.
Elite Sports Injury Management
You probably already know that a sports injury can affect not only your performance but also your lifestyle. The latest research continues to change sports injury management considerably. Our challenge is to keep up to date with the latest research and put them to work for you.
How we treated you last year could vary significantly from how we treat you this year. The good news is that you can benefit considerably from our professional knowledge.
What Should You Do When You Suffer a Sports Injury?
Rest from painful exercise or a movement is essential in the early injury stage. "No pain. No gain." does not apply in most cases. The rule of thumb is - don't do anything that reproduces your pain for the initial two or three days. After that, you need to get it moving, or other problems will develop.
Ice or Heat?
We usually recommend avoiding heat (and heat rubs) in the first 48 hours of injury. The heat encourages bleeding, which could be detrimental if used too early. In traumatic injuries, such as ligament sprains, muscle tears or bruising, ice should help reduce your pain and swelling.
Once the "heat" has come out of your injury, you can use heat packs. We recommend 20-minute applications a few times a day to increase the blood flow and hasten your healing rate. The heat will also help your muscles relax and ease your pain. If you're not sure what to do, please call us to discuss your situation specifically.
Should You Use a Compressive Bandage?
Yes. A compressive bandage will help to control swelling and bleeding in the first few days. In most cases, the compressive dressing will also help support the injury as you lay down the new scar tissue. This early healing should help to reduce your pain. Some injuries will benefit from more rigid support, such as a brace or strapping tape. Would you please ask us if you are uncertain about what to do next?
Gravity will encourage swelling to settle at the lowest point. Elevation of an injury in the first few days is beneficial, especially for ankle or hand injuries. Think where your damage is and where your heart is. Try to rest your injury above your heart.
What Medication Should You Use?
Your Doctor or Pharmacist may recommend pain killers or an anti-inflammatory drug. It is best to seek professional advice as certain medications can interfere with other health conditions, especially asthmatics.
When Should You Commence Physio?
In most cases, "the early bird gets the worm". Researchers have found that the intervention of physiotherapy treatment within a few days has many benefits. These include:
- Relieving your pain quicker via joint mobility techniques, massage and electrotherapy
- Improving your scar tissue using techniques to guide the direction it forms
- Getting you back to sport or work quicker through faster healing rates
- Loosening or strengthening of your injured region with individually prescribed exercises
- Improving your performance when you return to sport - we'll detect and help you correct any biomechanical faults that may affect your technique or predispose you to injury.
What If You Do Nothing?
Research tells us that injuries left untreated take longer to heal and have lingering pain. They are also more likely to recur and leave you with either joint stiffness or muscle weakness. It's important to remember that symptoms lasting longer than three months become habitual and are much harder to solve. The sooner you get on top of your symptoms, the better your outcome.
What About Arthritis?
Previously injured joints can prematurely become arthritic through neglect. Generally, there are four main reasons why you develop arthritis:
- An inappropriately treated previous injury (e.g. old joint or ligament sprains)
- Poor joint positioning (biomechanical faults)
- Stiff joints (lack of movement diminishes joint nutrition)
- Loose joints (excessive sloppiness causes joint damage through poor control)
What About Your Return to Sport?
Your physiotherapist will guide you safely back to the level of sport at which you wish to participate. If you need guidance, ask us.
What If You Need Surgery or X-rays?
Not only will your physio diagnose your sports injury and give you the "peace of mind" associated, but they'll also refer you elsewhere if that's what's best for you. Think about it. You could be suffering needlessly from a sports injury. Would you please use our advice to guide you out of pain quicker? And for a lot longer.
If you have any questions regarding your sports injury (or any other condition), don't hesitate to get in touch with your physiotherapist to discuss. You'll find our friendly staff happy to point you in the right direction.

Who is a Sports Physiotherapist?
Sports Physiotherapy is the specialised branch of physiotherapy which deals with injuries and issues related to spokespeople. Practitioners with additional formal training within Australia are Sports & Exercise Physiotherapists.
What is Sports Physiotherapy?
Sports injuries do differ from common everyday injuries. Athletes usually require high-level performance and demand placed upon their body, which stresses their muscles, joints and bones to the limit. Sports physiotherapists help athletes recover from sporting injuries and provide education and resources to prevent problems.
Each sports physiotherapist usually has sport-specific knowledge that addresses acute, chronic and overuse injuries. Their services are generally available to sportsmen and women of all ages engaged in sports at any level of competition.
Members of Sports Physiotherapy Australia (SPA) have experience and knowledge of the latest evidence-based practice, professional assessment and diagnosis of sports injuries, and effective hands-on management techniques and exercise protocols to assist recovery and prevent future damage. SPA members have access to the most recent advances in sports physiotherapy. You'll be pleased to know that most PhysioWorks physiotherapists and massage therapists have a particular interest in sports injury management.
