Background: There is little evidence demonstrating how self-reported outcome measures capture change during the first six months after anterior cruciate ligament (ACL) reconstruction.

Objectives: To describe changes in pain, function,and quality of life for patients within the first six months after ACL reconstruction, and to propose optimal sequencing of questionnaires that capture this information within this time period.

Methods: Twenty-two males and twenty-two females (mean age 27.39 years) completed four outcome measures at specific time intervals during six months of post-operative physical therapy. Regression curves were created to describe changes during this time period. Standardized Response Means were calculated for each measure at specific time intervals.

Results: The LEFS and the P4 documents captured the most standardized change in the first time interval. Most measures showed the most change in the first nine weeks after surgery.

Conclusion: The LEFS and the P4 appeared to capture change most effectively in the early post-operative period.
