Implication

Case series reveals collagen fiber continuity between bone and tendon in revision ACL reconstruction patients, indicating adequate graft osteointegration within 6 to 15 weeks.

Key Points

To assess the histological osteointegration of four-strand hamstring tendon autografts at the bone-tendon junction following anterior cruciate ligament reconstruction.
Histological analysis of bone-tendon junction specimens retrieved from two patients undergoing revision surgery following traumatic mid-substance graft rupture.
Grafts ruptured at 6 and 10 weeks post-reconstruction and were retrieved during revision surgeries at 12 and 15 weeks.
Initial reconstructions utilized a four-strand hamstring tendon autograft with round-headed, cannulated, interference (RCI) screw fixation.
Histological examination demonstrated graft osteointegration marked by continuous collagen fibers bridging the bone-tendon junction.
Effective osteointegration occurred between 6 and 15 weeks after reconstruction with RCI screw fixation.
