What happens to scar tissue during the remodeling phase?

During the remodeling phase of healing, scar tissue undergoes significant changes that contribute to its overall strength and functionality. The correct answer highlights that scar tissue becomes stronger and more organized.

This phase can last for months to years, during which the collagen fibers present in the scar tissue align better along the lines of stress, improving its tensile strength. The initial formation of scar tissue typically produces a disorganized matrix of fibers, which can be weaker and less functional than normal tissue. However, with time and appropriate stress applied through rehabilitation, the collagen fibers reorganize, cross-link, and become denser, leading to enhanced structural integrity.

Additionally, the remodeling phase helps to restore some of the normal functionality of the tissue affected by the injury, although scar tissue may not completely replicate the original tissue. Understanding this process is crucial for athletic trainers to develop effective rehabilitation programs that promote optimal healing and recovery.
