Residual remnant tissue preservation of the anterior cruciate ligament (ACL) has attracted notice in ACL reconstruction. There is a possibility that residual remnant tissue preserving technique has several potential advantages to accelerate the graft remodeling, such as improved anterior knee laxity, accelerated cell infiltration and revascularization, increased mechanoreceptors, and reduction of bone tunnel enlargement. Recently, the authors reported a new remnant tissue preserved procedure for anatomic double-bundle (DB) ACL reconstruction using the transtibial tunnel technique. The anterior and rotational knee laxities were significantly less in the remnant-preserved group than in the remnant-resected group. The 2nd look observation showed that the remnant-preserved group was significantly better than the remnant-resected group. In this article, the authors described the surgical technique and clinical outcomes of the residual remnant preserving DB ACL reconstruction.
