[Arthroscopically assisted anterior cruciate ligament reconstruction using patellar tendon autograft fixed with interference screw].
OBJECTIVE
To evaluate the optimal position of bony tunnel, the firmness of tendon graft fixation and the effectiveness of postoperative function recovery in an arthroscopic approach for the minimally invasive reconstruction of anterior cruciate ligament (ACL).


METHODS
In a single arthroscopic approach, the ACL was reconstructed by the bone-tendon-bone compound patellar tendon autograft with the fixation of an interference screw.


RESULTS
ACL reconstruction was performed in 49 patients, of whom 20 were followed up for over one year (average 1 year and 5 months). Among the 20 patients, 13 were rated as excellent, 5 good, and 2 fair. The excellent and good rate went up to 90%. Reconstructed ACLs were reevaluated arthroscopically in 9 patients, in whom, 6 had good remodeling of ACLs.


CONCLUSIONS
Our results indicated that this method has the advantages of less injury, optimal positioning of bone tunnel, firm graft fixation, and early rehabilitation. Compound bone-tendon-bone autograft allows firm fixation and biologic healing with good shape and tension remodeling.
