Posterior tibial slope is linearly related to anteroposterior shift of the tibiofemoral contact mechanics: A biomechanical study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To investigate the changes in tibiofemoral contact mechanics following an infra‐tubercle slope‐modifying osteotomy. Methods An infra‐tubercle slope‐modifying osteotomy was performed on eight fresh‐frozen cadaveric knees and fixed with an external fixator, which allowed for accurate slope adjustments from 15° to 0° in 5° increments. The

Knee joint line obliquity alters lateral meniscal root tension, tibiofemoral subluxation and compartment‐specific contact pressures

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The objective was to measure effects of joint line obliquity (JLO) on meniscus posterior root tension, tibiofemoral subluxation and contact pressures. It was hypothesised that a medial JLO would increase medial meniscal (MM) root tension, medial tibiofemoral subluxation and medial compartment contact pressure, and vice versa for ...

Evaluation of the theoretical optimal angle of the tibial tunnel in transtibial anatomic posterior cruciate ligament reconstruction by computed tomography

BMC Musculoskeletal Disorders, 2018
Background “Killer turn” effect is a critical explanation for the recurrent posterior laxity following transtibial posterior cruciate ligament (PCL) reconstruction, which affected by the angle of the tibial tunnel. Meanwhile, excessive tunnel angle would

Association between tibiofemoral bone and meniscus morphology and dynamic tibiofemoral movements during jump‐landing tasks in patients following ACL reconstruction

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To investigate whether tibiofemoral bone and meniscus morphology were associated with dynamic anterior tibial translation (ATTd) and internal tibial rotation (ITRd) during jump‐landing tasks in anterior cruciate ligament (ACL)‐reconstructed knees. Results may provide some guidance on the use of additional surgical procedures alongside (

Anatomical study of the positioning of guide wires for the reconstruction of the two bands of the anterior cruciate ligament using transtibial technique [PDF]

Acta Cirúrgica Brasileira, 2012
PURPOSE: To determine whether it is possible and the difficulty of anatomical placement of guide wires for reconstruction of the two bands of the anterior cruciate ligament using transtibial technique and to measure the angle and positioning of the ...

Magnetic resonance imaging‐based axial‐plane analysis of lower extremity torsion with dedicated 3D planning software is reliable and efficient

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The reliability and efficiency of a dedicated 3D planning software were evaluated for magnetic resonance imaging (MRI)‐based measurement of femoral torsion, tibial torsion, knee version and whole‐lower extremity torsion compared with manual assessment.

Reduced patella medialization in valgus and varus knees using a KA‐optimized femoral component in kinematically aligned TKA

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Patellofemoral complications after total knee arthroplasty (TKA) are linked to femoral component design and trochlear alignment. This study compared the effects of a kinematically aligned (KA)‐optimized femoral component versus a standard design on patellofemoral kinematics, contact mechanics and quadriceps function, using native knee ...

Medial meniscus posterior root repair with concomitant centralization does not demonstrate superior reduction of meniscal extrusion or improved clinical outcomes compared with isolated repair: A systematic review and meta‐analysis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate whether the addition of a meniscal centralization procedure to medial meniscus posterior root (MMPR) repair improves medial meniscus extrusion (MME) and patient‐reported outcomes compared with isolated MMPR repair. Methods A systematic review and meta‐analysis were conducted in accordance with Preferred Reporting Items for ...
