Independent clinical appraisal of the Tape Locking Screw (TLS®) anterior cruciate ligament reconstruction technique compared with the hamstring graft technique with a minimum of 12-month follow-up

Introduction The aim of this study was to assess the differential laxity after reconstruction of the anterior cruciate ligament (ACL) by the TLS® technique using a single tendon, the semitendinosus in four-strand graft, compared with the hamstring technique which uses both the gracilis and semitendinosus. We hypothesised that this surgical technique would provide post-surgical differential laxity measurements at least as good as those of the hamstring technique.
