Are clicky & noisy knees normal?

Does you knee click, crack or making grinding noises? Is this normal?

Noisy knees (also known as crepitus) are common: a previous study that examined 250 asymptomatic knees, found that 99% of them had this crepitus.

We still don’t know exactly what causes this noise, and it is more common in those with patellofemoral pain, BUT this noise is NOT a sign of severity: a 2018 study by Silva et al found that those with knee pain and noisy knees have the same strength, function & pain vs those with knee pain without noise (de Oliveira Silva, D., et al. 2018).

So in summary, whilst they might not sound nice, noisy knees are common and normal!
