In a retrospective study to determine whether the efficacy of
intra-articular reconstruction of the anterior cruciate ligament is
improved by an extra-articular transfer of the biceps femoris tendon, we
compared the results in a group of forty-three patients in whom the
advancement procedure had been done with those in a group of fifty patients
in whom it had not. The minimum length of follow-up was twenty-four months.
There was no significant difference between the two groups, and we
concluded that advancement of the biceps femoris tendon does not improve
the efficacy of an intra-articular reconstruction of the anterior cruciate
ligament.
