I too have had quite a few knee surgeries. Meniscus tear repair. Lateral release, Patellar dislocation, then Patellar groove deepening(to help stop dislocation. Unicompartmental surgery.
My right kneecap xray looks just like yours. The lateral release op was supposed to allow the kneecap to move into the right alignment, It was not that effective and caused a fair amount of scar tissue.
My left kneecap dislocated when I trod on a rock while running.It caused mild damage to the cartilage and I had an arthroscopy. The surgeon deepened the Patellar groove, and told me mine was very shallow, and that made it easy for the kneecap to dislocate.
This was successful and did not have any after effects.
Cycling and running strengthen the outside muscles of your quads, and there is often a muscle imbalance between the outside and inside thigh muscles. Particularly the vastus medialis ,which only works fully when you straighten your leg fully, which you dont do in cycling and running.
Therefore you have to spend valuable time working on strengthening these.
A good sports physio will show you the right excersises and give you a program to do.
If you injure your knee, the vastus M shuts off and you are even more vulnerable to the kneecap tracking incorrectly.
this is my experience.
Make sure you get really good advice ,and don’t opt for surgery unless the strengthening and physio etc doesn’t work for you.
Hope it goes well!
PS I consulted Professor David Barrett who is an internationally renowned knee surgeon.
He did my successful surgeries.
