A member asked:

What causes extreme crunching under the patella nine months after total knee replacement?

5 doctors weighed in across 2 answers

Not sure what....: ..."extreme crunching" is, but if that knee was operated on nine months ago, you need to see your surgeon for an evaluation.

Specializes in Orthopedic Surgery

Crunch patella: Likely scar or synovitis. Possible maltracking, loosening, implant position, noncompliance with stretching exercises.
