Based on

This course reports on a single peer-reviewed cross-sectional study that compared early initiation of physical therapy, defined as a structured program begun within 2 weeks of surgery, with delayed initiation, defined as a program begun at or after 4 weeks, following primary ACL reconstruction. The study included 132 adults, 66 in each group, recruited at a tertiary orthopedic surgery and sports medicine rehabilitation hospital in Khamis Mushait, with data collected from May 2023 through March 2024. Every participant was assessed at a single follow-up visit between 6 and 12 months after surgery.

All figures, findings, and conclusions in this course come from that report. Where the study authors issued recommendations, those recommendations are attributed to them.

After completing this course, you will be able to:

1. Describe the clinical question this study addressed about the timing of structured physical therapy after ACL reconstruction, including how the authors defined early and delayed initiation.
2. State the direction of the findings for function, strength, motion, and proprioception in the group that began rehabilitation within two weeks of surgery.
3. Explain the design limitations the authors identified, including the cross-sectional structure and the baseline differences between groups, and how those limitations shape interpretation of the results.
