Harmless Knee Noises
- Painless clicking when going up stairs — very common, usually patellofemoral crepitus
- General grinding sensation without pain in middle-aged adults
- A click that has been present for years without change or pain
- Clicking immediately after prolonged sitting
Warning Signs — Get Evaluated
See a Doctor if Your Knee Clicking is Associated With:
Pain with the click · Swelling · Locking — knee that will not fully straighten · Giving way · New onset after an injury · Progressive worsening · Associated warmth and redness
Common Causes of Significant Knee Clicking
Meniscus Tear
The meniscus can develop a flap tear that catches during movement — causing clicking, pain, and occasionally locking. Diagnosed on MRI and treated with arthroscopy.
Loose Bodies
Fragments of cartilage or bone floating inside the joint — can cause catching, clicking, and occasional locking. Removed arthroscopically.
Plica Syndrome
A fold of the joint lining that thickens and snaps over the femoral condyle with movement. Causes clicking and anterior knee pain in young active patients.
When to Stop Worrying
If your knee clicks without pain, without swelling, without giving way, and has been doing so for years without change — it is almost certainly benign. A single clinical evaluation to confirm this gives significant peace of mind.
