Posterior tibial slope varies across functional tibial phenotypes but not CPAK categories: A radiographic analysis from the FP‐UCBM Knee Study Group

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The relationship between the coronal and sagittal planes of the knee remains largely unexplored. The aim of this study was to evaluate the correlation between Posterior Tibial Slope (PTS), Hirschmann's functional tibial phenotypes, CPAK categories, and their defining parameters, hypothesising that coronal and sagittal tibial parameters

Unrestricted kinematic alignment on the sagittal plane: Posterior tibial slope and combined flexion do not have boundaries to respect in terms of short‐term clinical outcomes and safety

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Personalized alignment in total knee arthroplasty (TKA) is gaining traction as a surgical philosophy. True personalization, however, must encompass not only the coronal plane but also the sagittal and axial planes. This study evaluates influence of the Tibial Slope (PTS) and combined flexion (CF) on outcomes in TKA performed using ...

Kinematic alignment, but not mechanical alignment, preserves the knee–ankle relationship after total knee arthroplasty: A retrospective radiographic analysis from the FP‐UCBM Knee Study Group

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
ABSTRACT Purpose Several alignment strategies have been proposed in total knee arthroplasty (TKA), with the two extremes being mechanical alignment (MA) and unrestricted kinematic alignment (KA). While MA standardises coronal knee parameters to achieve a neutral alignment, KA reproduces each patient's native joint lines.

Efficacy of functional alignment in total knee arthroplasty in restoring in vivo cruciate ligament forces and knee kinematics compared with mechanical alignment

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The impact of coronal alignment on cruciate ligament forces in bicruciate‐retaining total knee arthroplasty (TKA) remains unclear. We aimed to clarify in vivo cruciate ligament forces and knee kinematics among mechanically aligned (MA) and functionally aligned (FA) TKAs and normal knees.

Dynamic coronal plane knee alignment: Femoral anatomy determines kinematic curve morphology, tibial anatomy determines curve position

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose A single hip–knee–ankle angle (HKA) angle does not reflect the biomechanics of native, arthritic or prosthetic knees. Since HKA varies throughout flexion, dynamic coronal alignment is best represented by a kinematic curve plotting HKA against the range of motion.

Tibial morphological difference between metal augmentation and actual tibia for revision total knee arthroplasty

Knee Surgery & Related Research
Background An overhang of the tibial component can cause irritation of the surrounding soft tissues, whereas an underhang is associated with risks of tibial bone resorption. It is not well known whether the tapering angle of currently available blocks at

Additional lateral meniscus centralization reduces residual anterolateral rotatory instability after anterior cruciate ligament reconstruction and lateral meniscus repair

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This study aimed to examine the effects of lateral meniscus (LM) centralization on anterolateral rotational stability in patients with anterior cruciate ligament (ACL) and LM injuries. The hypothesis was that performing LM repair and centralization on knees with LM lesions would control anterolateral rotatory instability (ALRI ...

Diagnostic value of the patellar tendon–lateral trochlear ridge distance and the patellar tendon–trochlear groove angle in differentiating lateral patellar instability from malalignment‐induced patellofemoral pain

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare the patellar tendon–lateral trochlear ridge (PT‐LTR) distance and patellar tendon–trochlear groove angle (PT‐TGA) between patients with lateral patellar instability (LPI) and those with malalignment‐induced patellofemoral pain (PFP), and to evaluate their differential diagnostic validity.

Posterior tibial slope measurement on lateral radiographs shows increased variability, reduced repeatability and risk of misclassification in osteoarthritic versus nonosteoarthritic knees

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The primary aim was to compare the variability and repeatability of medial posterior tibial slope (MPTS) measurements on lateral knee radiographs between osteoarthritic (OA) and non‐OA knees, and the secondary aim was to assess their implications for clinical classification.
