Biomechanical Superiority of the Chinese Knotting Technique in Posterior Cruciate Ligament Reconstruction: A Cadaveric Study

Orthopaedic Surgery, Volume 18, Issue 10, Page 2183-2194, October 2026.
In cadaveric PCL reconstruction, the Chinese knotting technique preserves graft mechanics, significantly increases maximum load, and limits elongation, supporting early rehabilitation and reducing failure risk. ABSTRACT Objective We previously developed a novel internal tension‐relieving augmentation suture, the Chinese knotting technique (CKT), which ...

Combined Effects of Polyethylene Wear Particle Size and Dosage on Macrophage Responses

, 2011
Ultrahigh molecular weight polyethylene (UHMWPE) wear particles-induced osteolysis and aseptic loosening is the main reason causing the failure of the total joint replacement. It is believed that cytokines, such as tumor necrosis factor-alpha (TNF-alpha),
