Purpose: As the number of the anterior cruciate ligament (ACL) reconstruction has increased, the incidence of revision of ACL reconstruction due to reconstruction failure has been also increased. Therefore, authors analyzed the reason of the failure of ACL reconstruction and the clinical result of the ACL revision.
Materials and Methods: From February 1998 to July 2010, we selected 36 cases which was followed at least 12months after the ACL reconstruction failure. Duration from reconstruction to revision, the average duration was 60 months (5~334) and on first reconstruction, we used allograft on 23 cases (63.9%) and autograft on 13 cases (36.1%). For the main symptom of ACL reconstruction failure, instability was the most common symptom, and 35 cases (97.5%) were undergone only one reconstruction and 1case (2.5%) was undergone two reconstruction. Clinical results were evaluated by Lysholm knee joint score, pivot shift test, and Telos device.
Results: Average follow-up duration of the patients was 21 months (12~40), and the reason for the ACL reconstruction failure, trauma was most common by 19 cases (52.8%), malposition of the femoral tunnel was 13 cases (36.1%), malposition of the tibia tunnel was 1case (2.8%), and failure of osteointegration was 3 cases (8.4%). On performing the ACL revision, we used allograft on 34 cases (94%) and autograft on 2 cases (6%), and 21 cases accompanied injury of the meniscus (medial meniscus 14 cases, lateral meniscus 7 cases). Lysholm knee joint score was improved from 66.5 points, preoperatively to 92 points on last follow-up (p<0.01). In most cases, patients were satisfied (92%) with the operation results. Tegner activity score was also improved from 2.0 points preoperatively to 6.2 points on the last follow-up. On Lachman and pivot sift test, 33 cases and 30 cases were improved to grade I respectively, and on stability test using Telos device, the bilateral difference was improved from mean 15.5 mm preoperatively to 4.5 mm on the last follow-up.
Conslusion: After 1 year follow-up, Revision of ACL had a little anterior instability but it showed satisfactory result on clinical result and patient’s subjective satisfaction.
