Which phase encompasses the longest duration in the healing process?

The maturation phase encompasses the longest duration in the healing process. This phase, also known as the remodeling phase, can last from several months up to several years, depending on the type and severity of the injury. During this period, the collagen fibers in the damaged tissue are gradually reorganized, realigned, and cross-linked to increase tensile strength. The tissue continues to remodel itself as it heals, which can involve changes in organization, structure, and composition to return to normal function.

The maturation phase follows the acute phase, which is focused on inflammation and the initial healing response, and the sub-acute phase, which involves tissue repair and the formation of new tissue. While these earlier phases are crucial in the healing process, they typically last a shorter duration compared to the extensive remodeling and strengthening that occurs during the maturation phase. Petrissage, on the other hand, refers to a specific massage technique and is not a phase of healing at all, hence is not relevant in this context.
