KOOS for Joint Replacement (KOOS-JR): Knee Outcomes
The KOOS-JR is a short survey that tracks knee health before and after joint replacement. Patients report on pain and stiffness to help doctors monitor recovery progress.

KOOS for Joint Replacement (KOOS-JR)
The KOOS for Joint Replacement (KOOS-JR) is a concise survey designed to track knee health before and after total knee replacement. Focusing on stiffness, pain, and function, this short-form tool helps clinicians monitor recovery outcomes. It's a reliable way to assess joint health throughout the treatment process.

What is KOOS for Joint Replacement (KOOS-JR)
The KOOS for Joint Replacement (KOOS-JR) is a focused survey for tracking total knee replacement results. It helps clinicians measure joint health quickly and simply. This tool strips back the longer questionnaire to just seven essential items. It focuses strictly on what matters most for patients with end-stage knee osteoarthritis. Patients answer questions about stiffness, pain during movement, and difficulty with daily tasks like rising from sitting, twisting, or bending. We calculate these responses to give a single interval score, where higher numbers mean a much healthier knee. Since it is short, it takes less than two minutes to finish, which is a real bonus for busy clinics. It reduces the burden on patients while keeping the data accurate. Clinicians use it to check progress before and after surgery, ensuring the recovery plan works well for the individual patient.
The KOOS for Joint Replacement (KOOS-JR) is scored by turning raw numbers into a metric score. First, you'll sum the responses from the seven survey items. Each question is rated from 0 to 4, giving a raw total between 0 and 28. Next, use the provided conversion table to swap this raw sum for an interval score ranging from 0 to 100. In this system, 0 means total knee disability and 100 indicates perfect knee health. This interval score allows for accurate tracking of patient progress over time, making it easier to spot real changes in joint function.
