Advantages and Limitations of the Technique

Advantages	Limitations
No donor site morbidity	Two-stage procedure
Technically simple and quick bone-grafting procedure	Transtibial approach not possible if previous femoral tunnel was in anatomic position
Cannulated design ensures precise and secure placement.	Expense of allograft
Maximizes potential for integration of allograft with the possibility to soak in platelet-rich plasma or bone marrow aspirate concentrate	High-load activity restriction after first stage
Replaces bony void	Increased time of return to sport due to delay of second stage
Optimizes bone tunnel placement for revision anterior cruciate ligament reconstruction
