The ST tendons are whipstitched at the looped The ST tendons are whipstitched at the looped end, forming a tight bundle that is “press-fit” end, forming a tight bundle that is “press-fit” placed into the femoral tunnel. This allows placed into the femoral tunnel. This allows RIGIDfix absorbable pins to cross the graft in RIGIDfix absorbable pins to cross the graft in any plane and provide rigid fixation.any plane and provide rigid fixation.
