Ballet dancer patient, Natalya tore her ACL during a rehearsal. She did not want to use her hamstring to repair her ACL. She came to The Stone Clinic where Dr. Stone reconstructed the injury using donor tissue. Dancers cannot afford to lose a portion of their patella tendon or their hamstrings. So, when the ACL is completely ruptured, we reconstruct it with a donor bone-patellar tendon-bone graft, pre-loaded with the patient’s own stem cells. During surgery, the graft is placed so as to permit the knee to extend equally to the opposite knee—which, for many dancers, actually means hyperextension. Traditional graft placements often did not allow this extra motion. Without it, though, the dancer would never be the same.
