Effects of total knee arthroplasty on ankle alignment in patients with varus gonarthrosis : do we sacrifice ankle to the knee? [PDF]

, 2015
Total knee arthroplasty is one of the most commonly preferred surgical methods in the treatment of patients with varus gonarthrosis. In this study, we aimed to evaluate the radiological changes observed in the ankles after total knee arthroplasty ...

Abduction and adduction malpositioned lateral radiographs cannot be used for proper assessment of the posterior tibial slope

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare medial posterior tibial slope (mPTS) measurements on abduction/adduction malpositioned versus properly positioned lateral knee radiographs within the same patients. We hypothesized that malpositioning would significantly alter mPTS values and potentially change surgical classification at the commonly used 12° threshold for ...

Variability of the femoral mechanical-anatomical axis angle and its implications in primary and revision total knee arthroplasty: an analysis of 2,156 knees using a deep learning tool

Bone & Joint Open
Aims: Distal femoral resection in conventional total knee arthroplasty (TKA) utilizes an intramedullary guide to determine coronal alignment, commonly planned for 5° of valgus.

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

Influence of Sex and Body Size on the Validity of the Microsoft Kinect for Frontal Plane Knee Kinematics During Landings

Sensors
Three-dimensional (3D) motion capture is inaccessible, and the Microsoft Kinect is an alternative to measure surrogates of knee valgus that may contribute to anterior cruciate ligament (ACL) injury risk. We evaluated the influence of sex and body size on

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.
