Alternate Design IdeasSince Dr. Kumbar expressed a
desire to use a hamstring graft instead of a bone block graft, we have begun working on alternate designs for our device
Eliptical Cavity instead of circular to increase amount of material supporting the hamstring graft

Interference Screw DesignPitch = 8Length = 30mm (typical for tibial
design)Diameter = 10mmThreads dulled since used for
securing soft tissue graft◦Sharper on the tapered end of screw
