Enhanced Mid‐Flexion Stability in Cruciate‐Sacrificing Total Knee Replacement: Impact of Optimized Implant Designs Investigated Using Musculoskeletal Multibody Simulation

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Total knee replacement (TKR) is a successful intervention for relieving pain and improving quality of life. In this context, mid‐flexion instability and paradoxical anterior femoral movement remain challenging. However, the role of implant design in cruciate‐sacrificing (CS) scenarios is unclear.

Preserving Patient‐Specific Knee Motion: A Randomized Clinical Trial of Unicompartmental and Total Knee Arthroplasty

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Unicompartmental knee arthroplasty (UKA) may enable improved functional outcomes compared to total knee arthroplasty (TKA). This randomized controlled trial assessed pre‐ and postoperative patient reported outcome measures (PROMs) and knee joint gait biomechanics for UKA and TKA patients.

Chondral lesions in the patellofemoral joint in MRI: Intra-individual comparison of short-tau inversion recovery sequence (STIR) with 2D multiple-echo data image combination sequence (MEDIC)

European Journal of Radiology Open, 2016
Purpose: To determine the value of the 2D multiple-echo data image combination (MEDIC) sequence relative to the short-tau inversion recovery (STIR) sequence regarding the depiction of chondral lesions in the patellofemoral joint.

Magnetic Resonance Imaging of Patellofemoral Morphometry Reveals Age and Gender Variations in the Knees of Children and Adolescents

Diagnostics, 2021
Background: The morphology and alignment of the patellofemoral joint are crucial risk factors for patellar instability, and the incidence of acute primary patellar dislocation is the highest in women in their second decade of life.

Patellar and Femoral Bone Morphology Is Associated With Overweight and Sports Participation in Young Adolescents

Journal of Orthopaedic Research, EarlyView.
ABSTRACT High levels of physical activity or high BMI during puberty could negatively influence bone and cartilage development. Little is known about the effects of loading on patellar and femoral bone shape in a young population. Therefore, we aim to identify the association between 3D patella and femur shape and biomechanical loading in a young ...

Knee muscle strength and movement biomechanics in individuals with and without knee pain after anterior cruciate ligament reconstruction: A cross‐sectional study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
ABSTRACT Purpose Anterior cruciate ligament injury increases the risk of knee osteoarthritis, possibly via early onset of knee pain and changes in musculoskeletal function. This study compared knee muscle strength and movement biomechanics during walking and forward lunge between individuals with and without knee pain after anterior cruciate ligament ...

Landmarks to guide femoral insertion in lateral patellofemoral ligament reconstruction: An in vivo assessment of isometry

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Lateral patellofemoral ligament (LPFL) reconstruction addresses medial patellar instability, but uncertainty regarding the optimal femoral attachment site may affect isometry and increase complication rates. This study aimed to establish landmarks for the femoral attachment of the LPFL graft based on in vivo isometry during active knee
