Fat Pad Impingement
Fat pad impingement, also known as Hoffa’s syndrome, is a condition where the soft fat pad beneath the kneecap becomes pinched between the bones of the knee joint. This can cause pain at the front of the knee, swelling, and difficulty fully straightening the leg. Physiotherapy treatment is highly effective in reducing inflammation, restoring knee movement, and correcting the underlying causes of the problem.
What is Fat Pad Impingement?
The knee contains a soft tissue structure called the infrapatellar fat pad, located just below the kneecap (patella). Its main role is to act as a cushion and reduce friction between the bones during movement.
Fat pad impingement occurs when this fat pad becomes irritated and gets pinched between the kneecap and the thigh bone. This repeated pinching leads to inflammation, pain, and restricted movement.
The condition is commonly referred to as Hoffa’s syndrome and typically causes pain at the front of the knee, especially when the knee is fully straightened.
Causes
Fat pad impingement usually develops due to repetitive stress or direct compression of the fat pad.
Common causes include:
- Forceful straightening of the knee (e.g., kicking or landing from a jump)
- Repetitive knee extension movements
- Swelling of the fat pad after minor injury
- Scar tissue formation following knee surgery
- Poor knee biomechanics
- Muscle imbalances around the knee
- Overuse in sports involving running or jumping
These factors increase pressure on the fat pad, making it more prone to irritation and inflammation.
Symptoms
Symptoms of fat pad impingement are usually felt at the front of the knee.
Common symptoms include:
- Pain just below the kneecap
- Pain when fully straightening the knee
- Swelling around the front of the knee
- Tenderness below the kneecap
- Stiffness in the knee joint
- Discomfort during walking, running, or jumping
- Thickened or firm tissue under the kneecap (in chronic cases)
Symptoms may worsen with activities that involve knee extension or impact.
What Should I Do?
If you suspect fat pad impingement, early management can help reduce symptoms and prevent worsening.
You should:
- Avoid activities that increase pain (running, jumping, deep squats)
- Apply ice to the front of the knee for 15–20 minutes
- Rest the knee and reduce repetitive stress
- Seek physiotherapy assessment as soon as possible
Early physiotherapy treatment helps reduce inflammation and improve recovery.
Physiotherapy Treatment
Physiotherapy is highly effective in treating fat pad impingement (Hoffa’s syndrome).
At ACE Physio Sports, physiotherapists provide a personalised treatment plan based on your condition.
Treatment may include:
Electrotherapy
Modalities such as ultrasound or TENS may help reduce pain and inflammation.
Strengthening Exercises
Exercises focus on strengthening the muscles around the knee, especially the quadriceps, to improve joint stability.
Range of Motion Exercises
Gentle exercises help restore normal knee movement and reduce stiffness.
Proprioception Training
Balance and coordination exercises improve knee control and reduce stress on the joint.
Hydrotherapy
Water-based exercises allow safe movement while reducing load on the knee.
Movement Correction
Physiotherapists assess and correct movement patterns to prevent repeated impingement.
A structured physiotherapy program helps restore knee function and prevent recurrence.
What Shouldn’t I Do?
If you have fat pad impingement, avoid:
- Ignoring persistent knee pain
- Continuing high-impact activities
- Deep knee bending or locking the knee repeatedly
- Returning to sports too early
- Self-treating without proper assessment
These actions can worsen inflammation and delay recovery.
Long-Term Effects or Recovery
When treated early, fat pad impingement usually resolves without long-term problems.
With appropriate physiotherapy:
- Pain and inflammation can be reduced
- Knee movement can be restored
- Normal activity levels can be resumed
If left untreated, the condition may lead to:
- Chronic knee pain
- Persistent inflammation
- Reduced ability to participate in sports
Early treatment ensures better outcomes and faster recovery.

Frequently Asked Questions
Why does my knee hurt when I go up or down stairs?
Stair pain is a hallmark of many knee conditions, including Fat Pad Impingement. Stairs significantly increase the load through the knee joint and surrounding structures. Physiotherapy identifies where the weakness or irritation lies and targets it with specific exercises.
My knee swells after activity — is that serious?
Post-activity swelling in Fat Pad Impingement indicates the knee is being irritated beyond its current tolerance. Physiotherapy can reduce inflammation, help modify your activity load, and progressively build the knee's capacity to handle more demand.
Can I still exercise with Fat Pad Impingement?
Yes — low-impact exercise like swimming, cycling, and targeted strength training is usually fine and beneficial. Your physiotherapist will identify which activities are appropriate and create a programme that builds knee strength without aggravating your condition.
