Can you explain the fulkerson osteotomy surgery?

Osteotomy: A fulkerson ostetomy involves cutting the tibial tuberosity, which in the site of attachment of the patellar tendon on the tibia (shin bone). The location of the tuberosity is then adjusted. It is typically performed for arthritis, and patellar instability.

Kneecap realignment.: It is a cut into the bony prominence on the front of your shinbone, where the patella/patellar tendon complex insert. It is then moved and fixed back into the shin bone, in a position where your kneecap will not dislocate or cause pain any longer.
