Abstract

Anterior cruciate ligament (ACL) reconstruction is one of the most common surgical procedures in orthopedics [1], and the number of ACL revision surgeries is increasing concomitantly [2]. ACL revision surgery is more technically demanding and final results are less satisfactory than primary surgeries [2]. In the ACL revision surgery both autografts or allograft can be used [3]. The choice is related to the surgeon’s experience and donor site morbidity. The autografts more commonly used are bone-patellar tendon-bone (BPTB) or hamstrings. Considering the primary ACL reconstruction, they have shown satisfactory strength and incorporation [4], and better results compared to the allograft, but there is insufficient data about the results of revision ACL surgery with the use of allografts. However, in ACL revision cases, donor site morbidity may be a problem, mainly in second or third revisions. The purpose of this study is to evaluate the results of ACL surgery comparing the results of cases in which autografts or allografts have been used.
