Fat pad impingement | Orthopaedics | Welbeck

Fat pad impingement usually causes pain at the front of the knee. The symptoms can vary depending on how severe the inflammation is.

Common symptoms include:

• pain at the front of the knee, especially just below or around the kneecap

• tenderness when pressing either side of the patellar tendon

• swelling or a feeling of fullness in the front of the knee

• pain when straightening the knee fully

• discomfort when standing for long periods

• pain during activities like walking, running, squatting, or climbing stairs

• a feeling of catching or pinching in the knee

• reduced range of movement due to pain

In some cases, the knee may look slightly swollen or puffy at the front. Symptoms often worsen with repeated activity or after long periods of standing.

Fat pad impingement develops when the fat pad becomes irritated or repeatedly compressed. This can happen suddenly after an injury or gradually over time.

Common causes include:

• direct injury to the front of the knee, such as a fall or blow

• repetitive strain from activities like running or jumping

• overextension of the knee (locking the knee straight frequently)

• poor movement patterns during exercise

• muscle imbalances around the knee and hip

• previous knee surgery or injury

Risk factors

Some factors may increase your risk of developing fat pad impingement:

• being physically active, especially in sports that involve running or jumping

• having weak or tight muscles around the knee

• poor posture or alignment of the lower limb

• wearing unsuitable footwear

• returning to exercise too quickly after injury

If you’re experiencing ongoing knee pain, it’s important to see a specialist for an accurate diagnosis.

At your initial consultation, your orthopaedic consultant will:

• ask about your symptoms, activity levels, and medical history

• examine your knee, including how it moves and where the pain is located

• check for swelling, tenderness, and signs of instability

In many cases, fat pad impingement can be diagnosed based on your symptoms and a physical examination.

However, your consultant may recommend further tests to confirm the diagnosis or rule out other conditions. These may include:

• ultrasound scan

• MRI scan

• X-ray (to assess bone structure and exclude other causes of pain)

These tests help your consultant understand the extent of inflammation and ensure you receive the most appropriate treatment.

While it’s not always possible to prevent fat pad impingement, there are steps you can take to reduce your risk.

These include:

• avoiding locking your knees when standing

• building strength in the muscles around your knee and hip

• warming up properly before exercise

• increasing activity levels gradually

• wearing supportive, well-fitting footwear

• maintaining good posture and movement technique during exercise

• taking rest periods to avoid overuse

If you’ve had a previous knee injury, following a structured rehabilitation plan can also help reduce the risk of recurrence.

Fat pad impingement is not usually a serious condition, but it can become persistent if left untreated.

Possible complications include:

• ongoing knee pain that affects daily activities

• reduced mobility and flexibility

• weakness in the surrounding muscles due to reduced use

• changes in movement patterns, which may lead to other injuries

In rare cases, chronic inflammation can lead to thickening (fibrosis) of the fat pad, making symptoms more difficult to treat.

Early assessment and treatment can help prevent these complications and improve outcomes.

Treatment for fat pad impingement focuses on reducing inflammation, relieving pain, and improving how your knee moves. Your consultant will refer you to a specialist physiotherapist who will provide you with a plan tailored to your needs.

Most people respond well to conservative (non-surgical) treatment and see improvement over time.

Treatment options may include:

• rest and activity modification – reducing or avoiding movements that trigger pain

• physiotherapy – exercises to strengthen muscles, improve flexibility, and correct movement patterns

• pain relief medication – such as paracetamol or nonsteroidal anti-inflammatory drugs (NSAIDs)

• ice therapy – applying ice packs to reduce swelling and discomfort

• taping or bracing – to support the knee and reduce pressure on the fat pad

• steroid injections – to reduce inflammation in more persistent cases

• surgery – rarely needed, but may be considered if symptoms do not improve with other treatments
