Case report: revision anterior cruciate ligament reconstruction

A case report is presented in which a professional football player, who was 4 years status post anterior cruciate ligament (ACL) reconstruction with autogenous patellar tendon, ruptured his graft. The contralateral patellar tendon was not available as a graft because of a more recent ACL reconstruction using that autogenous patellar tendon. This case reports the use of a previous donor site for supplying a patellar tendon autograft. Biopsy of the donor graft was consistent with normal tendon. The use of a healed patellar tendon donor site is a viable option for revision anterior cruciate reconstructive surgery. This option prevents the possibility of disease transmission with use of an allograft. We have shown grossly and histologically that the donor site has the potential to regenerate to tissue that has the appearance of normal tendon. This option could be available for revision surgery, but would not be recommended if the initial surgery was < 18 months-2 years in the past.
