Is bone tunnel osseointegration in hamstring tendon autograft anterior cruciate ligament reconstruction important?

A 27-year-old man underwent anterior cruciate ligament (ACL) reconstruction using 4-strand hamstring autograft with femoral and tibial interference screw fixation. Four weeks after surgery, he developed a discharging hematoma through the graft harvest-tibial tunnel incision, which persisted. The patient required further surgical intervention 7 weeks after the initial surgery. The wound was debrided, the tibial interference screw was removed, and the tibial tunnel was completely cleared of graft remnants. Arthroscopy of the knee was performed, in which the ACL graft appeared healthy and viable. No evidence of intra-articular sepsis was found. Postoperatively, the rehabilitation program was uneventful and, at 36 months, the patient has unrestricted activity and no clinical evidence of excessive ACL laxity. This case supports the importance of marginal articular surface healing of the ACL graft, suggesting that tibial intratunnel healing becomes redundant
