Effect of tibial slope on the stability of the anterior cruciate ligament–deficient knee

Abstract

Tibial slope changes did not affect the magnitude of translation during a Lachman test. However, large changes in tibial slope variation affected the magnitude of the pivot shift.

Combined Biplanar High Tibial Osteotomy, Anterior Cruciate Ligament Reconstruction, and Abrasion/Microfracture in Severe Medial Osteoarthritis of Unstable Varus Knees

“…16,17,19 Closedwedge osteotomies tend to yield a slope decrease, whereas newer open-wedge techniques might unintentionally lead to a slope increase. 51 Cadaveric and clinical studies have shown decreased anterior translation of the tibia if the slope is decreased in ACL-deficient knees.…”

“…[13][14][15] Apart from deformity correction in the coronal plane, osteotomies can strongly influence the sagittal plane by consciously or unconsciously altering the tibial slope. [16][17][18][19] Although being well accepted in the treatment of posterior and posterolateral instabilities, the role of slope modifications in ACL-deficient knees is still not well understood. 16 Numerous studies have investigated combined approaches of osteotomy and ACLR in early or imminent osteoarthritis as salvage procedures for young patients.…”

Posterior Tibial Slope Influences Static Anterior Tibial Translation in Anterior Cruciate Ligament Reconstruction

“…5,[15][16][17]20 Giffin et al 5 17 reported that the changes in tibial shear force, ACL force, and ATT were linearly related to the change in PTS using a 3-dimensional musculoskeletal model. The authors reported that a 5°increase in PTS resulted in a 2-mm increase in ATT when standing.…”

An Evaluation of the Association Between Radiographic Intercondylar Notch Narrowing and Anterior Cruciate Ligament Injury in Men: The Notch Angle Is a Better Parameter Than Notch Width

“…35,36 In addition, an increased posterior tibial slope may be associated with ACL injuries because of increased torsional loads in cases of differences in the medial and lateral tibial slopes. 35,37 The investigation of the posterior tibial plateau is still pertinent because it has been found that patients with an increased slope have a higher risk of ACL reinjury after ACL reconstruction. 38 Further research should determine the role of tibial plateau depth and meniscal slope in the risk of ACL injury in male patients.…”
