ClinConnect Summary

This clinical trial is looking at how knee extension loss after surgery to repair a torn anterior cruciate ligament (ACL) affects recovery. Specifically, the study will compare muscle strength and overall knee function in two groups of patients: those who have a loss of knee extension (more than 5 degrees) shortly after their surgery and those who do not. Understanding this difference is important because having a good range of motion in the knee can help patients recover stronger and avoid long-term pain.

To participate in this study, patients need to be between 18 and 45 years old, have had ACL surgery using a specific type of graft from their hamstring, and must have been active before their injury. They also need to attend their rehabilitation sessions regularly after surgery. If someone has had other knee surgeries or certain medical conditions, they may not be eligible. Participants will be followed closely to see how well they regain strength and function in their knee, which will help improve rehabilitation practices in the future.
