Abstract
A surgical method for transosseous fixation of a BTB graft into a joint is disclosed. A longitudinal tunnel formed in a bone is intersected by a transverse pin. A flexible strand is drawn with the pin through the bone. A looped portion of the strand is diverted so as to protrude out of the entrance to the longitudinal tunnel. The loop is severed so that one end of the strand is passed through a hole in the bone block of the BTB graft. The free ends of the loop are subsequently reattached using a knot to form a reformed loop. The strand with the reformed loop is retracted into the tunnel, drawing the attached BTB graft into the tunnel. The BTB graft is fixed in the tunnel using a transverse implant.
Claims13
A method of anterior cruciate ligament reconstruction, comprising the steps of:
- forming a tibial tunnel between an anterior tibial surface and the tibial plateau;
- forming a femoral tunnel having an opening and a sidewall;
- introducing a first strand into the femoral tunnel through said sidewall;
- pulling said first strand through said opening of said femoral tunnel and down through said tibial tunnel;
- severing said first strand to obtain at least two severed strands;
- attaching one of said severed strands to a bone block of a bone-tendon-bone graft;
- subsequently reattaching said severed strands to form a reformed first strand;
- and
- pulling said reformed first strand attached to said bone block of said bone-tendon-bone graft into said femoral tunnel.
A method of anterior cruciate ligament reconstruction, the method comprising the steps of:
- forming a tibial tunnel between an anterior tibial surface and the tibial plateau;
- forming a femoral tunnel having an opening and a sidewall;
- introducing a suture into the femoral tunnel through said sidewall;
- pulling said suture through said opening of said femoral tunnel and down through said tibial tunnel;
- severing said suture to obtain at least two severed strands;
- passing one of said severed strands through a hole in a bone block of a bone-tendon-bone graft;
- subsequently reattaching said severed strands to form a reformed suture;
- lifting said bone block of said bone-tendon-bone graft into said femoral tunnel;
- and
- supporting said bone-tendon-bone graft into said femoral tunnel by using a transosseous implant.
