Hi, one of my girls has had both legs done successfully with TPLO. I dont live in the US so cant comment on your surgeon. I found the yahoo group orthodogs very helpful.
orthodogs : Discussion of canine orthopedic issues
The moderators are very experienced with cruciate injuries and they or some of the members will be able to help you with your questions as they seem to know most of the surgeons.
They will also be able to give you detailed information on TPLO surgery which requires cutting the tibia in the leg and repositioning it so that the head of the bone is level and acts as a stop to the bone above it which is what the cruciate ligament does when it is functioning properly.
This is different from the traditional method where artificial ligaments are used to stabalise the knee untill scar tissue has developed. There is often heated discussion to the pros and cons of each surgery.
I am happy with my TPLO surgeries and my dog is back competing in agility. This particular dog by the way is an Australian cattle dog.
Anyway goodluck and remember that the first 8 weeks till bone healing are key to the success. It took my dog 3-4 months to recover fully and 8 months till I trialed her again in agility.
