A Case of Revision Anterior Cruciate Ligament Reconstruction with Hamstrings Tendon for Residual Rotatory Instability after Primary Reconstruction with Bone-Patella Tendon-Bone

Abstract

Revision anterior cruciate ligament (ACL) reconstruction surgery has become increasingly common. A 21-year-old woman was performed primary ACL reconstruction with bone-patella tendon-bone (BTB) on the left knee at 17 year. After ACL reconstruction, she sometimes felt instability and complained about giving way on the reconstructed knee. She developed pain from 18 year. No limitation of motion was showen but positive anterior drawer test, pivot shift test and McMurray test on the physical examination at 21 year. We performed revision ACL reconstruction, which was preserved primary graft and augmented with hamstrings tendon and medial meniscus was repaired. At 14 months after operation, she has no complain subjectively and no rotatory and antero-postarior instability has restrained. We believe this technique offers a reasonable approach to revision ACL surgery in the properly indicated patients, especially for the rotatory istability.
