The bone-patellar tendon-bone has been widely used and considered a good graft source. The quadriceps tendon was introduced
as a substitute graft source for bone-patellar tendon-bone. We compared the clinical outcomes of anterior cruciate ligament
reconstructions using central quadriceps tendon-patellar bone and bone-patellar tendon-bone autografts. We selected 72 patients
who underwent unilateral anterior cruciate ligament reconstruction using bone-patellar tendon-bone between 1994 and 2001 and
matched for age and gender with 72 patients who underwent anterior cruciate ligament reconstruction using quadriceps tendon-patellar
bone. All patients were followed up for more than 2 years. We assessed anterior laxity, knee function using the Lysholm and
International Knee Documentation Committee scores, and quadriceps strength, the means of which were similar in the two groups.
More patients (28 or 39%) in the bone-patellar tendon-bone group reported anterior knee pain than in the quadriceps tendon-patellar
bone group (six patients or 8.3%). Anterior cruciate ligament reconstruction using the central quadriceps tendon-patellar
bone graft showed clinical outcomes comparable to those of anterior cruciate ligament reconstruction using the patellar tendon
graft, with anterior knee pain being less frequent in the former. Our data suggest the quadriceps tendon can be a good alternative
graft choice.
