📄 Abstract:
Meniscal root tears compromise knee joint biomechanics and are associated with early-onset osteoarthritis. This study introduces a novel self-tension screw designed to enhance meniscal root repair by providing controlled tensioning during fixation. Biomechanical testing demonstrated that the self-tension screw offers improved load distribution and stability compared to conventional fixation methods. The design considerations focus on optimizing mechanical properties to mimic native meniscal function, potentially leading to better clinical outcomes.
