What is the purpose of this trial?

This trial aims to evaluate how well athletes recover after knee (ACL) or hip surgery using a special gadget called the Moxy sensor, a wearable device. The sensor measures muscle oxygen levels, helping doctors better understand recovery and determine when athletes can safely return to their sport. Participants include two groups: those who have undergone surgery and healthy individuals without knee or hip surgery, for comparison. This trial is ideal for athletes aged 14 to 30 who have had ACL or hip surgery and wish to return to sports. As an unphased trial, it offers athletes a unique opportunity to contribute to research that could enhance recovery strategies and improve return-to-sport timelines.

Do I need to stop taking my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that the Moxy Oxygen Sensor Device is safe for monitoring post-surgical rehabilitation?

Research shows that the Moxy Oxygen Sensor Device is easy to use and doesn't cause discomfort. Top athletes favor it because it doesn't require blood tests or lab visits, making it non-invasive. This means it doesn't need to break the skin or enter the body. Studies confirm it provides real-time information on muscle oxygen levels, allowing for easy monitoring without discomfort.

The physical therapy component is also safe. Research has found that physical therapy after surgery can improve strength and knee function. These programs are usually light to moderate and designed to be safe for those recovering from surgery, typically including regular sessions with breaks in between.

Overall, both the Moxy Oxygen Sensor and the physical therapy are considered safe and easy to tolerate. They have been used successfully in other cases, suggesting they should be safe for participants in this trial. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the potential of wearable sensor monitoring in post-surgical sports rehabilitation because it offers a fresh approach to tracking recovery. Unlike traditional methods that rely heavily on subjective assessments and periodic check-ins with therapists, this approach uses the Moxy Oxygen Sensor Device to provide continuous, real-time data on muscle oxygenation during workouts. This can lead to more personalized and precise adjustments in physical therapy, potentially accelerating recovery times and improving outcomes for patients recovering from ACL or hip surgeries.

What evidence suggests that the Moxy Oxygen Sensor Device is effective for post-surgical sports rehabilitation?

Research has shown that the Moxy Oxygen Sensor Device, which measures muscle oxygen levels, can help predict muscle recovery after surgery. Studies have found that this device provides information that improves training by accurately controlling exercise intensity. Early results suggest that monitoring muscle oxygen offers valuable insights into recovery progress. In this trial, some participants will use the Moxy Oxygen Sensor Device during their monitored workouts.

Physical therapy has also proven effective. Studies indicate that pre-surgery physical therapy can enhance knee function and strength afterward. Exercise therapy significantly boosts muscle strength and overall recovery. In this trial, participants will undergo physical therapy as part of their rehabilitation. Combining monitoring and therapy may help athletes recover effectively after surgery. ^{1 2 3 6 7}

The Moxy muscle oxygen monitor reliably measures local oxygen saturation (SmO2) at low to moderate exercise intensities, showing strong correlations between trials and with whole-body oxygen consumption (VO2).

However, its reliability decreases at higher intensities, likely due to increased movement artifacts, and total hemoglobin (THb) measurements do not effectively indicate muscle oxygenation during exercise.
