Remodeling phase of ligament healing is characterized by which changes?

In the remodeling phase of ligament healing, the tissue shifts toward becoming a stronger, more organized ligament. The key changes are realignment of collagen fibers to match the direction of tissue strain, and a maturation of the collagen matrix from Type III to Type I. Type III collagen is the initial, softer form laid down during early healing; as remodeling proceeds, fibroblasts reorganize the fibers and replace much of the Type III with the stronger Type I collagen, increasing tensile strength and stiffness. This is why the option describing fibers reoriented along the tissue strain and Type I collagen replacing Type III best fits remodeling. Other statements don’t fit because end-feel changes aren’t the defining feature of this phase, scar tissue isn’t stuck with Type III indefinitely (it progressively shifts to Type I), and healing isn’t completed in just 2-4 weeks—the remodeling phase lasts longer, often months, as strength and structure continue to improve with use and loading.
