Hoffa's Fat Pad Impingement
What Is Hoffa's Fat Pad Impingement?
The fat pad sitting behind the kneecap — known as the infrapatellar or hoffas fat pad — is a cushioning structure that normally moves freely as the knee bends and straightens, helping absorb shock and reduce friction within the joint. Hoffa’s fat pad impingement, sometimes written hoffa fat pad impingement or referred to simply as hoffa pad impingement, occurs when this fat pad becomes pinched between the kneecap and thigh bone, most often during repeated knee extension, leading to irritation, swelling, and pain.
Left untreated, ongoing knee fat pad inflammation can make the fat pad more prone to further impingement, creating a cycle of irritation and swelling.
Symptoms of Fat Pad Impingement
impingement knee pain or general fat pad knee discomfort. Other common symptoms include:
- Pain that worsens with fully straightening the knee, or standing for long periods
- Swelling around the front of the knee, sometimes described as an inflamed fat pad knee presentation
- Tenderness either side of the patellar tendon, where the fat pad is most accessible to touch
- A sense of fullness or thickening at the front of the joint, reflecting fat pad knee inflammation and swelling
Fat Pad Impingement Treatment at Alton Pain Clinic
At Alton Pain Clinic, we use ultrasound-guided cortisone injections for Hoffa’s Fat Pad Syndrome to support accuracy and precision during the procedure. Ultrasound guidance allows our clinicians to visualise the inflamed fat pad and surrounding knee structures in real time, helping to accurately target the affected area. This approach supports precise delivery of the cortisone while helping to minimise unnecessary exposure to nearby tissues.
Mechanism of Action: Cortisone in Treating Hoffa’s Fat Pad Syndrome
At Alton Pain Clinic, cortisone injections may help manage the symptoms of Hoffa’s Fat Pad Syndrome through:
- Anti-Inflammatory Effects: Cortisone helps reduce the inflammatory process and the production of substances that contribute to inflammation.
- Pain Reduction: By reducing inflammation, cortisone may help ease pain associated with Hoffa’s Fat Pad Syndrome and improve knee movement.
- Symptom Management: While cortisone is not a cure for the underlying condition, it may provide symptom relief and help make everyday activities more comfortable.
Benefits of Ultrasound-Guided Cortisone Injections
- Minimised Risk of Complications: The use of ultrasound guidance ensures that the injection is delivered exactly where needed, reducing the likelihood of complications.
- Quick Pain Relief: Patients often experience a reduction in pain shortly after the injection, allowing them to resume daily activities more comfortably.
- Non-Invasive Option: This method offers a less invasive alternative to surgical interventions, making it an attractive choice for conservative treatment.

What our Patients say?
How Is Fat Pad Impingement Diagnosed?
Diagnosis typically involves a Hoffa’s fat pad test — your clinician will passively extend your knee while applying gentle pressure to the fat pad, checking whether this reproduces your pain. This helps distinguish hoffa’s fat pad syndrome from other causes of anterior knee pain, such as patellar tendinopathy, which can present similarly. An ultrasound scan is often used to confirm hoffa’s fat pad impingement syndrome and assess the extent of any swelling or thickening.
Choosing Alton Pain Clinic for Hoffa’s Fat Pad Syndrome
At Alton Pain Clinic, we provide ultrasound-guided cortisone injections for suitable patients with Hoffa’s fat pad syndrome. Using real-time ultrasound guidance, our clinicians can accurately visualise the affected area and surrounding knee structures, supporting precise delivery of the injection. We take a personalised approach to treatment, assessing your symptoms and clinical needs to determine whether a cortisone injection is suitable for you.
Frequently Asked Questions
What is Hoffa's fat pad impingement?
Hoffa’s fat pad impingement occurs when the fat pad behind the kneecap becomes pinched between the kneecap and thigh bone, causing pain, swelling and irritation at the front of the knee.
How is fat pad impingement different from patellar tendinopathy?
Both cause pain at the front of the knee, but fat pad impingement typically worsens with full knee extension, while patellar tendinopathy is usually more related to jumping or loading the tendon. A clinical test and ultrasound scan help distinguish between the two.
What is Hoffa's syndrome?
Hoffa’s syndrome is another name for fat pad impingement — inflammation and irritation of the knee’s infrapatellar fat pad, usually from repetitive compression.
How long does fat pad impingement take to settle?
With appropriate activity modification and treatment, many patients notice improvement within a few weeks, though more persistent cases can take longer to fully resolve.
