[Double-barrelled replacement-plasty of the anterior cruciate ligament with fascia lata strips].

An intra-articular reconstruction of the anterior cruciate ligament (ACL) in chronic and acute ruptures is described, which we call doubling-back ACL substitution. The McIntosh graft is used to fix it, starting from the posterior origin of the ACL and passing to the anterior region of its insertion and through the anteromedial tibial head, returning over the top with isometric conditions. Since April 1987, this procedure has been applied in 60 patients this way, 48 of whom we saw again between April and June 1990. There are only 2 unstable joints; 46 patients have stable knees. Most of them are engaging in sport again.
