Anterior cruciate ligament rupture is the most common knee ligament injury. Of the grafts that are used for anterior cruciate ligament reconstruction, bone-patellar tendon-bone is still the most common because of its initial fixation stability and its ultimate tensile strength and elastic modulus, which are superior to those of other graft sources. Hamstring tendon grafts recently have demonstrated functional results equivalent to those of bone-patellar tendon-bone grafts. While most recent studies have failed to demonstrate significant differences between the two types of grafts, many authors have reported on their strengths and weaknesses1-12. While there has been a trend toward better stability in association with bone-patellar tendon-bone grafts, postoperative complications, including anterior knee pain and patellofemoral problems, have been reported frequently13-20. Knee-extension deficits have been reported to occur more frequently in association with bone-patellar tendon-bone grafts as compared with hamstring tendon grafts1,7. Graft laxity and tunnel enlargement have been reported in association with hamstring tendon grafts, and some authors have found persistent muscular deficits in knee flexion and internal rotation strength after treatment with hamstring tendon grafts5,21.
