  • Simulation of total knee arthroplasty in 5° or 7° valgus: A study of gap imbalances and changes in limb and knee alignments from native

    Simulation of total knee arthroplasty in 5° or 7° valgus: A study of gap imbalances and changes in limb and knee alignments from native

    Illustrations show the creation of a gap imbalance between the medial and lateral compartments at 0° flexion on an example native right lower limb caused by a simulated TKA set in 5° valgus. (A) The included angle between the anatomic axis of the femur and the extension of the anatomic axis of the tibia measured knee alignment which was 7.9° valgus in the native limb. (B) The resection of the distal femur 5° valgus to the femoral anatomic axis and the resection of the proximal tibia perpendicular to the tibial anatomic axis created a trapezoidal-shaped gap (i.e., gap imbalance between compartments at 0° of flexion). (C) To set the knee at 5° valgus, the tibia was rotated 2.9° varus to create a rectangular gap which generally would require release of lateral soft tissue structures and changed the knee alignment from native (i.e., from 7.9° valgus to 5° valgus).

  • Marker-based technique for visualizing radiolucent implant components in radiographic imaging

    Marker‐based technique for visualizing radiolucent implant components in radiographic imaging

    Setup for the knee RSA phantom model. The reference bead-inserted tibial liner was imaged with the RSA biplane cage.

  • Osteoarthritis alters the patellar bones subchondral trabecular architecture

    Osteoarthritis alters the patellar bones subchondral trabecular architecture

    Representative mineralization pattern according to the density distribution of the human patella (mg/ml calcium hydroxyapatite; left = lateral). a) Non-OA patella b) OA patella.

  • Systematic mapping of the subchondral bone 3D microarchitecture in the human tibial plateau: Variations with joint alignment

    Systematic mapping of the subchondral bone 3D microarchitecture in the human tibial plateau: Variations with joint alignment

    (a) 3D micro-CT image of an excised tibial plateau from a right knee (view from the top). The ellipses defining the medial and lateral tibial condyles are shown (dashed lines), containing the locations of the 22 tibial condyle subvolumes of interest (VOIs, red squares, 11 per condyle); (b) 2D coronal micro-CT cross-section image of the tibial plateau with medial and lateral boundaries of the ellipses indicated by red lines.

  • Lateral soft-tissue structures contribute to cruciate-retaining total knee arthroplasty stability

    Lateral soft‐tissue structures contribute to cruciate‐retaining total knee arthroplasty stability

    Illustration demonstrating the lateral structures with cruciate-retaining total knee arthroplasty (posterolateral view of a right knee).

  • Transplantation of human skeletal muscle-derived progenitor cells ameliorates knee osteoarthritis in streptozotocin-induced diabetic mice

    Transplantation of human skeletal muscle‐derived progenitor cells ameliorates knee osteoarthritis in streptozotocin‐induced diabetic mice

    Chondrogenic characteristics of human skeletal muscle progenitor cells (HSMPCs). Pellet culture was harvested after 21 days of standard chondrogenic differentiation (DM) or growth medium (GM). (A) Macroscopic view of chondrogenic pellets. Scale bar = 1 mm. (B) and (C) Representative sections of Alcian blue/nuclear fast red staining (B), Safranin O staining (C) and immunohistochemical images for the distribution of type-2 collagen (D) were shown. Scale bar = 100 µm. Results shown are representative at least three independent experiments.
