Restoring the quadriceps’ eccentric abilities post-ACLR: Unweighting and deceleration

Quadriceps function is vital for knee health. Quadriceps weakness is associated with an increased risk of reinjury, higher rates of knee osteoarthritis, persistent pain, progressive joint damage, and a greater likelihood of requiring joint-replacement surgery [2, 3, 4, 5]. Adding to the already steep challenges of anterior cruciate ligament reconstruction (ACLR) rehabilitation is the difficulty of restoring full lower limb function, particularly the strength and activation of the quadriceps muscle [1]. From a return to performance perspective, regaining quadriceps function is essential for res...
