"Knee Injury and Osteoarthritis Outcome Score" (KOOS)

The Knee Injury and Osteoarthritis Outcome Score (KOOS) is a questionnaire used by healthcare professionals to assess a person's knee health. It measures how knee problems affect daily life, including pain, stiffness, swelling, difficulty with activities like walking or stairs, and overall knee function. The questionnaire helps doctors understand the severity of knee issues and track progress over time, guiding treatment decisions and evaluating the effectiveness of therapies or surgeries related to knee injuries or osteoarthritis.
