Anyone have any insight on collateral ligament damage?  Did you rehab/rest horse, use any form of "help" for healing (PRP, shockwave or just rest?)  How long resting and did horse make full recovery to barrel racing again?  Any insight helpful! 

Which collateral lig. ?  (Hock, stifle, foot ?)

I had good success with using PRP and shockwave to heal collateral ligaments on each side of the fetlock.  I followed vet's orders to a T and also used magents and red light therapy combined with lots of prayers and hard work.  The horse did return to soundness and I was able to rope and run barrels on him after.
