instabilities

t is less severe than melt fracture but still affects product aesthetics. Mechanism: This instability is caused by a combination of surface shear stress and the viscoelastic nature of the polymer. When the shear stress at the die exit surpasses a critical thresh

ovations and Future Directions Biological and Regenerative Therapies Emerging treatments involve platelet-rich plasma (PRP), stem cell therapies, and growth factors to enhance ligament healing and regeneration. Biomechanical and Kinematic Assessments Advanced gait analysis and dynamic imaging p
