Hi, About 20 years ago I dislocated my patella laterally, a small fragment of bone came off the patella. 12 years ago I had a MPFL reconstruction. Recently I’ve experienced some clicking/grating around the reconstructed MPFL, my x rays still shows the Avulsion fragment of bone. My question is : is it usual to have this fragment of bone removed when first discovered ?. It hasn’t give me an issue until 4 months ago when I noticed the clicking/grating and the feeling of something loose around the MPFL ligament.
