Double-sided laser technology. One of the ACL spatial configuration locating methods. The central point of ACL was located and marked with gentian violet. The point C and D was aligned to create plane A using high-accuracy surface-type laser transmitter; The point C and D was aligned to create plane B using another high-accuracy surface-type laser transmitter; Plane A and B intersected a spatial line L, and line L passed through point C and D, and point C and D defined the ACL spatial configuration. Line L passed through the tibial exit point and femoral exit point as E and F, respectively. If the tunnel is straight, then CDEF is on the same line
