Summary
The modified bone-hamstring-bone (BHB) graft offers strong initial fixation for faster rehabilitation. This technique enhances graft security and promotes biological healing without causing patellofemoral issues.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomedical Engineering
Background:
- Graft fixation is critical for early rehabilitation in anterior cruciate ligament (ACL) reconstruction.
- Existing bone-patellar tendon-bone and hamstring tendon grafts have limitations.
- A hybrid approach may overcome these disadvantages.
Purpose of the Study:
- To describe a modified bone-hamstring-bone (BHB) composite graft procedure.
- To highlight the technique's advantages for graft fixation and patient outcomes.
Main Methods:
- A modified BHB composite graft technique is detailed.
- Cancellous bone cylinders are harvested and secured to the hamstring graft ends with sutures.
- Graft ends are pressed to achieve a diameter of 9-10 mm for strong fixation.
- Graft is inserted into tibial and femoral tunnels and secured with round cannulated interference screws (RCI).
Main Results:
- The modified BHB technique provides precise and strong initial graft fixation.
- This method promotes biological fixation, aiding graft incorporation.
- The procedure avoids patellofemoral joint complications.
Conclusions:
- The modified BHB graft technique ensures robust early fixation, crucial for rehabilitation.
- This hybrid graft method offers advantages over traditional techniques.
- The procedure is associated with favorable outcomes and no patellofemoral issues.
