Ligament tissue is how much weaker after injury?

• A. 10-20% weaker
• B. 40-60% weaker
• C. 60-80% weaker
• D. 30-50% weaker

Answer: (D)

After ligament injury, the tissue loses strength because the collagen fibers are damaged and heal with scar tissue that is less organized and less cross-linked. This makes the ligament’s tensile strength and stiffness notably lower. In clinical education, injured ligaments are typically weaker by roughly one-third to one-half compared with their normal state. That level of weakness helps explain why early protection and a carefully progressed loading program are essential during rehabilitation—to encourage proper remodeling and regain function without risking re-injury.
