Efficacy of a Squat Visual Biofeedback Program After ACL Reconstruction: Protocol for a Prospective, Parallel, Randomized Controlled Trial.

Background: Altered knee joint loading is pervasive and persistent after anterior cruciate ligament reconstruction (ACLR) and a significant driver for the development of knee osteoarthritis (OA).

Purpose: To describe a prospective, parallel, randomized controlled trial aiming to evaluate the efficacy of an eight-week squat visual biofeedback program implemented early after ACLR.

Study Design: Randomized controlled clinical trial.
