Why do my knees crunch when I squat?
Crepitus is the name for when a joint makes a noise in response to movement.
Generally, these little noises are normal age-related changes inside the joint.
The important thing to remember is that this knee clicking, crunching and cracking is commonly associated with normal knee function and is not something to be concerned about. Knees are complex moving parts and there are a number of structures involved when the knee is bent and straightened, for example in a squat.
However, if you are experiencing pain, swelling, or loss of normal motion in the knee along with crepitus, we recommend booking in with one of our physiotherapists for an evaluation.
