As incidence of anterior cruciate ligament (ACL) reconstruction increases, the rate of revision surgery also increases. Revision of a failed anterior cruciate ligament reconstruction is a complex procedure. There are many risk factors such as patient age, technical errors, trauma, infection, spontaneous biological failure in the failure of primary ACL reconstruction treatment. The most common cause of recurrent instability after ACL reconstruction is surgical technical errors. Inadequate tunnel placement is the most common cause of technical error. The causes of the primary ACL reconstruction failure should be determined, and careful surgical planning should be done accordingly. For this purpose, after taking a good history and physical examination, standard anterior-posterior (AP), lateral, tunnel radiographs, lower extremity orthoroentgenogram, magnetic resonance and tomography should be evaluated. Appropriate surgical technique should be chosen according to additional meniscus injuries, bone tunnels, cartilage injuries, bone deformity, presence of infection, graft options and patient activity level. Although revision ACL reconstruction has been documented to have worse outcomes compared with primary ACL reconstructions, satisfactory results can be achieved with good planning and appropriate technique.
