Which factor is a determinant of healing in musculoskeletal tissues?

• A. Type and extent of injury
• B. Regenerative capacity of tissue
• C. Vascular supply to tissue
• D. All of the above

Answer: (D)

Healing in musculoskeletal tissues is influenced by multiple interacting factors, and all of these play a determinant role. The type and extent of the injury set the initial challenge—more severe damage, larger gaps, or contamination complicate repair and slow progress. The tissue's regenerative capacity varies widely: bone tends to remodel effectively, cartilage and some tendons/ligaments heal slowly and may scar, while others have limited intrinsic regeneration. Vascular supply is crucial because blood brings oxygen, nutrients, and immune and growth factors necessary for healing; tissues with rich blood flow recover faster, whereas avascular or poorly vascularized tissues heal more slowly or incompletely. In practice, prognosis and rehab planning hinge on how severe the injury is, which tissue is involved, and how well it is supplied with blood.
