I talked w the vet again Monday...she said his patella is out more than in and is hard to get back into place...so i am thinking he is grade 3...she said some of this was due to the hip problem...and they have warned me that his recovery time will be especially important to allow time to heal correctly since he has altered anatomy...they have also told me that they are able to guarantee me 100% that it will stay in place even after surgery as he gets older and the hip continues to get arthritic, ect but this is the only chance he has at having at least one major joint in the leg stable...when i spoke w her and voiced my concerns about what i had been reading on this forum about luxating patella, she did tell me that he is not the normal case due to the hip, his femoral neck is completely gone and the femoral head sits on top of the femur which is really contributing to the LP problem...He is just so young to have a messed up leg so I feel like we have to fix the patella to give him a chance as he gets older...any thoughts? Tek's surgery is scheduled for Friday
