Efficacy of STABL Virtual Rehabilitation

Study Overview
=================
Brief Summary
-----------------
The purpose of the proposed study is to evaluate the efficacy of STABL rehabilitation vs in-person rehabilitation following meniscectomy or synovectomy. STABL is a digital health platform that uses computer-vision technology to facilitate at-home post-op recovery for patients while enabling remote monitoring by their surgeon.

Detailed Description
-----------------
Patients undergoing minor knee procedures (defined as meniscectomy and synovectomy) will be randomized to virtual rehabilitation using the STABL platform or standard physical therapy over the course of 6 weeks to determine any possible difference in clinical outcomes.

| Experimental: Rehabilitation using STABL platform<br>Patients undergoing minor knee procedures (defined as meniscectomy and synovectomy) will be randomized to virtual rehabilitation using the STABL platform | Behavioral: STABL Virtual Rehabilitation<br>* STABL is a digital health platform that uses computer-vision technology to facilitate at-home post-op recovery for patients while enabling remote monitoring by their surgeon. The platform is fully HIPAA compliant. STABL analyzes a patient's biomechanics in real time while they perform their recovery exercises to provide them with cues to ensure the exercises are done correctly and track adherence. They then relay all the data to the patient's clinician to allow them to monitor their recovery remotely, address any adherence barriers, and mitigate readmission risks that arise in a more timely manner.<br>|
| No Intervention: Rehabilitation using standard physical therapy<br>Patients undergoing minor knee procedures (defined as meniscectomy and synovectomy) will be randomized to standard physical therapy. | |

| Change in Visual Analogue Scale (VAS) Pain score | VAS is a tool widely used to measure pain. A patient is asked to indicate his/her perceived pain intensity (most commonly) along a 100 mm horizontal line, and this rating is then measured from the left edge (=VAS score). The total score range is 0 (no pain) to 10 (worst pain imaginable); the higher the score, the worse the pain. | Baseline, Week 3 |

| Change in ACL-Return to Sport (ACL-RSI) Scale Score | The ACL-RSI scale includes 12 questions on the patient's emotional well-being and confidence in his or her performance and risk appraisal. The scale, with scores ranging from 1 to 10, includes 5 questions on emotional well-being, 5 questions on confidence in physical performance, and 2 questions on the appraisal of risk. Higher scores indicate a more positive psychological response. The total score is determined by adding the values of the 12 responses and then calculating their relationship to 100 to obtain a percentage (0-100%). | Baseline, Week 3 |
