Eden - my Boxer bitch had a partial tear to a cruciate ligament, the Vet thought possibly more than 50% of the ligament was torn, when she was 6 years old.
A scan indicated approx 60% tear. I was given the choice - to operate or not. I chose to go for not operating and seeing how we got on because the op is so extreme (imo). Obviously this meant really curtailing her activities - not easy with a Boxer and even more difficult as her Boxer brother was also a very lively and playful dog. Anyway, for 4 weeks they were controlled so that there was NO play time when they were together - they were only allowed to lie down and cuddle up to each other. At walk times my dog was allowed out only on his own and he could play as much as he liked, then my bitch was taken out on lead (even in the garden) on her own and calm, gentle walking was enforced. I removed the sofas from my lounge and I sat on cushions on the floor, I removed the base of my bed and slept on the mattress on the floor!!! (No stairs to worry about as I live in a bungalow). I work full time, and don't have a partner, so my dog walker was given the same routine to follow, and she did, faithfully. There was significant healing identified at the 4 week scan, so we continued the regime for another 4 weeks, and the next scan showed great healing and thus the op was avoided. However obviously she has since been permanently at risk of damaging the ligament again so I enforced a complete ban on throwing toys of any sort - balls can ONLY be rolled on the floor and if one of the dogs throws one into the air they were immediately told No! Leave it! and fortunately they did. My Bitch will be 12 years old in a few months and although occasionally she shows a little stiffness in the limb she has never had a real problem with it. When she is stiff her exercise is cut accordingly.
Since all this my Dog has passed away, and we have welcomed a new puppy into the household, (this mainly for the benefit of my Bitch who went into an incredible period of mourning and totally lost the will to live after the older dogs death) and he is now almost 10 months old. All the same rules apply when the dogs are together, and when the puppy is playing without her many of the rules still apply as I don't want to risk him suffering such a problem.
So, my advice would be that if the Vet thinks there is a possibility of it healing alone then go for it, but you WILL need to be very strict, and at times it will break your heart to stop your dog from playing, but your heart will mend, and your dog could mend too without having to undergo such drastic action as a major op.
