Brief Summary

Anterior cruciate ligament (ACL) injuries account for up to 25% of knee injuries, it is estimated that 32,000-400,000 new cases of ACL tears occur in the USA every year. The Standard care is twofold; a) ACL reconstruction surgery and b) prolonged rehabilitation period (usually no less than 9 months). However, a large amount of patients do not return to their pre-injury activity level, and up to 30% reinjure their ACL in the following two years. The wearable system consists of two non-invasive bands, above and below the knee that vibrate during the weight bearing phase while walking.

Study Arms (3)

Usual care+ Sham device

NO INTERVENTION

Each participant will go through the normal rehabilitation process that follows ACL reconstruction+ a sham device used in the same was as the intervention group. The sham device will look the same, will gave the same pressure around the leg, but will not vibrate.

Usual care+ knee vibratory device

EXPERIMENTAL

Each participant will go through the normal rehabilitation process that follows ACL reconstruction. Additionally, each participant will receive the active device that applies non-invasive vibrational stimulation to the leg for two months, and will be asked to wear it during ambulation for at least an hour per day.

Device: Active vibratory knee device

Normative data

NO INTERVENTION

Healthy participants will go through one session of the full protocol (excluding blood tests): * Questionnaires (IKDC, TSK, GAD-7). * Biomechanical analysis during walking, stair ambulation, and hoping. * Quadriceps and Hamstring strength testing

Interventions

The active, wearable device is placed above and below the knee joint. The device consists of a sensing module to determine specific points in the gait cycle, a processor to analyze signal from the sensor, and a stimulus module to provide vibratory feedback to the subject.

Usual care+ knee vibratory device
