Pain NRS (Pain Numerical Rating Scale)
Subject rates pain from 0-10 with 0 being no pain and 10 being the worst pain
Knee Flexion and Extension Goniometry
A measurement of knee flexion and knee extension, using a goniometer, will be completed.
Gait Speed
Subject's gait speed will be measured in meters/second.
Knee Injury and Osteoarthritis Outcome Score, Junior (KOOS Jr)
Knee Injury and Osteoarthritis Outcome Score, Junior (KOOS Jr) is a short, 7-question survey used by doctors to quickly assess a patient's knee pain, stiffness, and daily function. The raw score is converted to a 0-100 scale with a score of 0 = total disability and 100 = full function without pain.
