A Wireless Visualized Sensing System with Prosthesis Pose Reconstruction for Total Knee Arthroplasty

Sensors, 2019
The surgery quality of the total knee arthroplasty (TKA) depends on how accurate the knee prosthesis is implanted. The knee prosthesis is composed of the femoral component, the plastic spacer and the tibia component. The instant and kinetic relative pose

Orthopaedic surgery [PDF]

, 2005
Over the past fifty years orthopaedic surgery made giant strides forward. It developed from a discipline that dealt primarily with the treatment of fractures, bone infections and tendon transfers and that treated degenerate joints by fusing them to one ...

Step‐by‐step insight into gait analysis: A narrative review unlocking knee biomechanics

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Gait analysis offers a powerful tool for clinical and orthopaedic decision‐making. By quantifying spatiotemporal, kinematic and kinetic parameters during walking, it provides a dynamic window into joint function that static imaging cannot capture.

Five‐year implant survival does not differ between hybrid and cementless total knee arthroplasty in a cohort of 5361 patients using a deep‐dish mobile bearing design

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This study compared total knee arthroplasty (TKA) outcomes between cementless and hybrid fixation, with separate analysis of tibial and femoral cementation. The primary hypothesis was that equivalence would exist in implant survivorship between cementless and hybrid fixation techniques.

Dynamic computed tomography assessment of patellofemoral and tibiofemoral kinematics before and after total knee arthroplasty: A pilot study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To develop and evaluate the clinical feasibility of a dynamic computed tomography (CT) protocol for assessing patellofemoral (PF) and tibiofemoral (TF) kinematics before and after total knee arthroplasty (TKA), and to quantify postoperative kinematic changes in a pilot study.

Unrestricted kinematic alignment in varus total knee arthroplasty outperforms mechanical alignment in CPAK I phenotype, but yields comparable outcomes in CPAK IV: A retrospective analysis from the FP‐UCBM Knee Study Group

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare clinical outcomes in varus‐aligned patients undergoing cruciate‐retaining total knee arthroplasty (TKA) with mechanical alignment (MA) versus unrestricted kinematic alignment (KA). The hypothesis was that KA would yield superior outcomes, and that preserving joint line obliquity—regardless of alignment technique—would be ...

Clinical application of the tibial extension stem in primary TKA for knee varus deformity combined with tibial bone defect

Frontiers in Surgery
ObjectiveTo observe the clinical efficacy of prophylactic use of tibial extension stem in primary Total Knee Arthroplasty (TKA) in patients with severe knee varus deformity and tibial plateau bone defect, and its effect on reducing the rate of tibial ...

The simulation for study of von Mises stress sensitiveness to the change of coronal conformity in knee prosthesis

MATEC Web of Conferences, 2017
Two-dimensional finite element contact modelling is often conducted to simulate the contact mechanism in knee prosthesis. This is based on the assumption that the contact stresses are more sensitive to change in the coronal plane than in the sagittal ...
