Both my Chows were diagnosed with this at 5 months, the x-rays showed it was severe with fragmented coronoid process.
I chose for them both to have the arthroscopic surgery straight away, the earlier it is done the better the outcome. They had to have 6 weeks cage rest and monthly pentosan injections for a year. After the recovery period I tried to walk them but it always left them lame, it was very hard.
Once they reached 2 years everything started to look up and I could walk them normally with no lameness at all, maybe something to do with them having finished growing?
I lost Balto last year to cancer but I still have his brother Baloo (7 years old) and although he has lots of problems with his hips, knees and ankles his elbows have held up fine.
I made my decision based on their age, they had their whole lives ahead of them, I didn't want them to possibly have a lifetime of pain medication, I wanted it over for them.
The hardest thing was the 6 weeks of cage rest, only going to the toilet on a lead, very hard on a puppy. It was worth it in the end, it was the right decision for us.
Good luck with whatever you decide.
