Avoiding graft-tunnel mismatch in endoscopic anterior cruciate ligament reconstruction: a new technique

A common problem encountered in endoscopic anterior cruciate ligament reconstruction is graft-tunnel mismatch. A technique not previously described in the literature is illustrated. This technique provides direct measurement of the tibial tunnel length plus the intra-articular distance. This allows direct calculation of the length of the femoral tunnel necessary to avoid a graft-tunnel mismatch. This technique has been used very effectively in our institution with excellent, reproducible results.
