Response: Hospital for Special Surgery (HSS) researchers saw the need for a shorter, more patient friendly outcome survey for revision knee replacement surgery. This is an area where patient-reported outcomes data are essential to improving quality of care. In fact, knee replacement revisions, which are more complex and heterogeneous than primary knee surgery, are under-studied in this regard.

A commonly used knee replacement survey, the KOOS (Knee Injury and Osteoarthritis Outcome Score), is 42 questions and often leaves physicians with partial and unusable information secondary to patient burden and fatigue. Previously, researchers at HSS created the KOOS, JR, which is a shorter, 7-question survey that accurately measures “knee health”, meaning it reflects aspects of pain, symptom severity, and activities of daily living relevant and difficult for patients with knee arthritis. The current research presented at AAOS showed that the KOOS, JR can be extended to knee replacement revision patients and that it is a valid and efficient tool for assessing knee health in this challenging patient population. What should readers take away from your report?

Response:  Knee replacement revisions are more complex than primary knee surgery and are expected to grow 600 percent in the coming years. With the uptick of these surgeries that is anticipated over the next 5 to 10 years, it is essential that we deepen our understanding of revision knee replacement outcomes.

The shorter patient survey will help the orthopedic community gain necessary data on pain and function for knee replacement revisions, while reducing the burden on patients and data collection administrators. What recommendations do you have for future research as a result of this study?

Response:  Validating the KOOS, JR is the first step to collecting more reliable patient-reported outcomes data on knee replacement revision surgery. By collecting more data in this area, we hope to accelerate our understanding of risk stratification, infection prevention and treatment, and implant designs to improve patient outcomes after revision knee replacement surgery.
