Unusual position of bone tunnels in failed ACL reconstruction.

Abstract

INTRODUCTION: Surgery of ACL deficient knees is very frequent nowadays due to advanced surgical techniques, sophisticated implants and large number of surgeons. Therefore, the number of revisions for various reasons is growing up. There are several well known reasons for failed surgery This paper reported a case of revision surgery in a patient with previously done and failed reconstruction of ACL. CASE OUTLINE: Reviewing the clinical findings and X rays we found out peculiar position of the transplant and tunnels as a cause of the failure. We haven't found such complication reported in literature therefore we decided to report the case. CONCLUSION: Variety of implants and instruments can ease the surgery but basic anatomical knowledge of position and relations of the knee ligaments are essential for good surgical outcome.
