ACL tears occur in a variety of sports, says Lyle Micheli, M.D.,
Director, Division of Sports Medicine at Children's Hospital Boston, and
require surgical repair as soon as possible to avoid the arthritic
changes associated with a delay in reconstructive surgery and,
hopefully, the need for more surgery later. While a failure rate of 20% is not
uncommon, the failure rate at Children's is much lower, around 5%.
