Stages of Tendon Healing ^{34 a}

Inflammatory Stage	Proliferative Stage	Remodeling: Consolidation Stage	Remodeling: Maturation Stage
24-72 h Erythrocytes and neutrophils Phagocytosis Vasoactive and chemotactic factors for vascular permeability Initiation of angiogenesis Stimulation of tenocyte proliferation and migration Initiation of type 3 collagen synthesis	3 d-6 wk Type 3 collagen synthesis (peak) High water concentration High GAG concentration	6-10 wk Decreased cellularity (collagen, GAG) Increased fibrous repair High tenocyte metabolism Tenocyte and collagen fibers align parallel to stress	10 wk-1 y Transition to scar-like tendon Decreased tenocyte metabolism Decreased vascularity

^a GAG, glycosaminoglycan.
