› 27487427 Posterior Tibial Slope: Effect on, and Interaction with, Knee


Background: Posterior tibial slope (PTS) is an important factor in the knee joint biomechanics and one of the bone features, which affects knee joint stability Posterior tibial slope. Posterior tibial slope has impact on flexion gap, knee joint stability and posterior femoral rollback that are related to wide range of knee motion.- Operative Considerations for Posterior Tibial Slope: - sagittal alignment of the tibial component is determined by amount of posterior slope of the proximal tibial cut; - most current systems strive for 3-7 deg of posterior slope, because bone in the anterior portion of the cut surface is weaker;The posterior slope of the tibia is a possible and long-debated factor that may affect the flexion angle. In cruciate-retaining (CR) prostheses, decreased posterior slope followed by tight flexion gap TKA requires posterior cruciate ligament (PCL) release to increase or maintain the flexion angle [ 7 ].The mean posterior tibial slope of those with a further ACL injury was 9.9° compared with 8.5° for those with no further injury (P = .001). The mean posterior tibial slope for those with both an ACL graft and contralateral ACL rupture was 12.9°.Background: Higher posterior tibial slope (PTS) is a risk factor for anterior cruciate ligament (ACL) injury in men and women. The individual contribution of the lateral (LPTS) and medial (MPTS) slope has not yet been investigated.The optimum posterior tibial slopes for fixed-bearing UKA patients with partial and complete ACLD are 5-7° and 5-6°, respectively.
