  1. Tiludronate was injected subcutaneously at 2 mg/kg, starting immediately on the day of ACL transection and repeated every two weeks for an eight-week follow-up. Placebo-control dogs received mannitol injection in a similar fashion.
  2. Data presented are mean (SD).
  3. Statistically significant Time effect (*), Group effect (§) and Time per Group interaction (¶)
