This occurred in the early infancy of ACL surgery and rehab. They really did not know what they were doing. It was a given at that time, that if you even suffered on ACL you would never fully recover your former quickness and agility. Exclusive of the surgery not being what it is today, even more, so they also knew very little about proper rehab. That was the reason why she had so many reoccurring ACL tears and surgeries.Five ACL tears in six years. Just looked it up.
