  • Kinematics of meniscal- and ACL-transected mouse knees during controlled tibial compressive loading captured using roentgen stereophotogrammetry

    Kinematics of meniscal‐ and ACL‐transected mouse knees during controlled tibial compressive loading captured using roentgen stereophotogrammetry

    Schematic of the joint axes and coordinate system relative to the tibia used for the kinematics analysis. Straight arrows indicate the Superior–Inferior axis (green), Medial–Lateral axis (red), and Posterior–Anterior axis (blue), and curved arrows indicate Internal–External (green), Flexion–Extension (red) and Adduction–Abduction (blue) rotations. Scale bar = 2.0 mm.

  • Rotator cuff repair using cell sheets derived from human rotator cuff in a rat model

    Rotator cuff repair using cell sheets derived from human rotator cuff in a rat model

    Safranin-O and fast green staining at 4 weeks postoperatively. In the repaired group, with a cell sheet at week 4, proteoglycan was observed with safranin-O and fast green staining at the enthesis (a and b), whereas less proteoglycan was seen in the control group (c and d). White square, repaired enthesis; *, articular cartilage; H, humers; T, tendon; all scale bars, 200 μm; original magnification, (a and c) ×20, (b and d) ×100.

  • Immune modulation with primed mesenchymal stem cells delivered via biodegradable scaffold to repair an Achilles tendon segmental defect

    Immune modulation with primed mesenchymal stem cells delivered via biodegradable scaffold to repair an Achilles tendon segmental defect

    Representative micrographs DiI-labeled MSCs within the Achille tendon 2 and 4 weeks post-injury. Images demonstrate DiI-labeled unprimed (a, c) and primed (b, d) MSCs at 2 (top row) and 4 weeks (bottom row). Scale bar = 100 um.

  • Factors regulating bone remodeling processes in aseptic implant loosening

    Factors regulating bone remodeling processes in aseptic implant loosening

    Double staining of PPTs with CD68 (brown) and S100a4 (red). Wear particles are found in multinucleated CD68 positive cells (*) and also in fibroblast-like cells which are positive for S100a4 (arrow) besides unstained mononuclear cells. Bar represents 20 μm.

  • Double plating in Vancouver type B1 periprosthetic proximal femur fractures: A biomechanical study

    Double plating in Vancouver type B1 periprosthetic proximal femur fractures: A biomechanical study

    Non-union and implant failure after comminuted periprosthetic femur fracture after THA. The fracture was fixed using lateral angular stable plating and additional cerclages.

  • Influence of trabecular bone quality and implantation direction on press-fit mechanics

    Influence of trabecular bone quality and implantation direction on press‐fit mechanics

    (A) Test apparatus simulating Axial (orange) and Radial (purple) press-fit. (B) A schematic of the test apparatus showing a section of the interface between the implant and trabecular bone tilted by an angle φ = 3.5° to the axial implantation direction. Positive axial and radial directions are indicated.
