My horse had one in a hind leg caused by an accident in turnout. He was totally sound on it after shock wave, rest, hand walking, etc, and was able to go back to work for some months.
Somehow, though healed, it must have very slightly changed the dynamics in the joint, because somehow, it allowed a tiny amount of pressure on an OCD he had in the joint since before I bought him (as a baby), causing an extremely subtle lameness - or as another vet said, itās just possible the clock rain out on the OCD - many people feel an OCD that isnāt currently causing problems never will, but Iāve heard from several vets it is no guarantee it wonāt cause a problem later. Once the OCD flared up, the prognosis was āgrave for staying pain free for upper level workā.
The lameness was not severe- not visible but I could feel it. Eventually, he had to be retired to light work. If the OCD hadnāt been there, we would have made it. The ligament injury could not even be detected with any imaging technique after his rehabilitation.
It is not usual for a horse to recover from a serious laterlal collateral ligament injury. When my horse got hurt I asked around - it is not common for them to go back to work from a serious injury to that ligament. I do not think my horseās injury was āseriousā. It resulted in a barely detectable lameness that most people probably wouldnāt have investigated. If a horse comes in from pasture on 3 legs, like Boleem did, I think thatās a āsevere ligament injuryā.
Not to say it does not happen, of course it does. Yours did. But just saying you are lucky.
I would think that uneven footing, studs, jumping and galloping would be a bad idea, but each injury is different and only your vet really can give you a good indication of what you should and shouldnāt do.
I should think xrays and ultrasounds or mris to keep an eye on the condition of the ligament would be a good way to monitor it. We take baseline pictures when we get a horse and re-take them every spring, we take new pictures if a problem comes up too.
