Hoffa's test is a physical examination maneuver used to assess for infrapatellar fat pad syndrome, a condition causing pain at the front of the knee.
Understanding Hoffa's Test
Here's a breakdown of what the test entails:
- Purpose: To identify pain originating from the infrapatellar fat pad, located just below the kneecap.
- Procedure:
- The examiner applies gentle pressure just below the kneecap.
- While maintaining that pressure, the patient's knee is passively extended (straightened).
- Mechanism: According to the referenced video, the test works by pushing the fat pad into the joint line between the femur and tibia, causing potential pain if inflammation exists.
What Happens During a Positive Test
A positive Hoffa's test is indicated by:
- Pain: The patient will experience pain when the knee is extended during the test, specifically in the area of the infrapatellar fat pad.
- Location: Pain is typically localized at the front of the knee, below the kneecap.
Why is Hoffa's Test Important?
- Diagnosis: It helps differentiate infrapatellar fat pad syndrome from other knee pain sources.
- Treatment Planning: Identifying the fat pad as the pain generator is crucial for guiding appropriate treatment strategies.
Key Takeaways
| Feature | Description |
|---|---|
| Test Goal | Identify infrapatellar fat pad pain. |
| Procedure | Apply pressure below the kneecap while passively extending the knee. |
| Positive Result | Pain felt when pushing the fat pad into the joint line during knee extension. |
| Significance | Helps differentiate fat pad issues from other knee problems. |
Hoffa's test is a valuable clinical tool for evaluating anterior knee pain and is best performed by qualified healthcare professionals.
