Use of a Wearable Muscle Oxygen Saturation Sensor in the Rehabilitation of High-School and Collegiate Athletes Recovering From Arthroscopic Hip and Knee Surgery

What this Trial Is About

This research aims to evaluate muscle oxygen saturation and hemoglobin levels in athletes recovering from arthroscopic surgery of the knee or hip, such as ACL tears or hip pathology. The study focuses on measuring recovery progress to support decisions on safe return-to-play. Data from patients undergoing surgery and healthy individuals are compared to enhance understanding of muscle function during rehabilitation. Participants will wear a Moxy sensor device, a non-invasive wearable that monitors oxygen and hemoglobin levels in the rectus femoris muscle during workouts and therapy sessions. Surgical patients will follow their institution's injury-specific physical therapy protocols, with assessments at set intervals: 6 weeks, 12 weeks, 6 months, and 9 months post-surgery. Healthy volunteers will perform a monitored one-hour exercise session for baseline comparison. Throughout the study, muscle oxygen saturation and hemoglobin levels will be recorded at the specified time points. Researchers will use this data to predict muscle function recovery in injured limbs compared to non-injured limbs and healthy controls. The trial will last up to 9 months for surgical patients, with a single assessment for healthy volunteers. Safety and progress will be monitored during regular clinic visits and physical therapy sessions.
