In evaluating an ACL donor graft site, which statement best describes the associated risk?

• A. It is typically assessed as a specific physical exam finding.
• B. It is not applicable; this is more a conceptual postoperative concern than a physical exam finding.
• C. It presents as local warmth and redness at the donor site.
• D. It causes immediate, severe instability on testing.

Answer: (B)

Donor graft site morbidity is a postoperative concern rather than a single, discrete exam finding. The risks at the harvest site—such as anterior knee pain, kneeling discomfort, numbness from nerves in the area, or transient weakness—are best understood as ongoing, patient-reported or functional outcomes after surgery, not as a specific preoperative physical exam sign. Signals like local warmth/redness would suggest infection, and immediate, severe instability would point to graft or joint failure, not the general donor-site risk profile.
