What causes reduced mobility during the tendon healing process?

Scar tissue formation significantly contributes to reduced mobility during the tendon healing process. When a tendon sustains an injury, the body initiates a healing response that involves the formation of scar tissue. This scar tissue is denser and less flexible than the original tendon tissue, which can restrict movement and flexibility at the injury site. As a result, the mechanical properties of the tendon are altered, leading to limitations in its ability to stretch and contract normally.

This formation of scar tissue is a natural part of the healing process, as it provides a temporary structural support while the tendon heals. However, the stiffness and adhesions associated with scar tissue can lead to discomfort and a reduced range of motion. Consequently, patients may experience difficulty in performing activities that require the full range of movement of the affected tendon.

Other factors such as collagen fiber thickness, muscle activity, and blood flow may play a role in the healing process but do not directly lead to the same level of mobility restriction as scar tissue formation. For instance, while thicker collagen fibers could indicate stronger tendons, the quality of the scar formed significantly impacts mobility more directly.
