Description
To determine the prevalence of an “increased posterior tibial slope (PTS)” (PTS ≥ 12°) in a population with one, two or ≥ three anterior cruciate ligament (ACL) graft insufficiencies. The secondary aims were to investigate if the prevalence of an increased PTS and the absolute PTS increases with the increasing number of ACL graft insufficiencies, as well as to investigate the survival time of the first ACL graft.
