• Evaluation of patients following knee ligament injuries (specifically ACL/PCL).
• Screening for symptoms of instability (giving way) and mechanical symptoms (locking).
• Standardized follow-up tool for ACL reconstruction outcomes.

The scores for all 8 items are summed for a total ranging from 0 to 100.

• The high weight given to "Instability" (25 pts) and "Locking" (15 pts) makes this scale very sensitive to failure of a ligament graft or a recurrent meniscal tear.
• Often paired with the Tegner Activity Scale to provide context on the patient's functional demand.
• Minimal Clinically Important Difference (MCID): Typically 10 to 15 points.

• Poor Score (<65): Correlates with significant functional disability; consider orthopedic re-evaluation for mechanical failure or instability.
• Fair Score (65-83): Suggests moderate symptoms; optimize neuromuscular control and proprioceptive training.
• Activity Context: Use the Tegner score to see if a "Good" score is being limited by the patient returning to high-impact elite sports.
