The donor piece may come from tendon taken from the patient. Usually, this comes from the injured leg, but it can come from the other leg.

Patellar fractures occur in about one percent of all cases when the patellar tendon is used as the donor tissue. The number of patellar fractures has decreased as more and more ACL repairs are done. There isn't a single cause of this fracture. In this study, eight people ended up with a patell...
