A 12-item short form of the Knee injury and Osteoarthritis Outcome Score (KOOS-12): tests of reliability, validity and responsiveness.
The purpose of this study was to evaluate reliability, validity and responsiveness of KOOS-12, a 12-item short form of the 42-item Knee injury and Osteoarthritis Outcome Score (KOOS) that provides Pain, Function and Quality of Life (QOL) scale scores and a summary knee impact score. Results showed that KOOS-12 was a reliable and valid alternative to KOOS in total knee replacement patients with moderate to severe knee osteoarthritis and provided three domain-specific and summary knee impact scores with substantially reduced respondent burden.

Listening to patients' voices: workarounds patients use to construct pain intensity ratings.
This study analyzed patients’ perspectives on constructing pain intensity ratings and workarounds used. Focus groups were conducted with thirty-one patients with osteoarthritis. Three emerging themes were found: 1) many factors affected patients’ perceptions and ratings of intensity, 2) patients used different approaches to evaluate pain, and 3) patients interpreted maximal response anchors differently. Activity items also helped patients to remember pain.

Preferences for physical activity: a conjoint analysis involving people with chronic knee pain.
The goals of this study were to investigate individual preferences for physical activity attributes in adults with chronic knee pain, to identify clusters of individuals with similar preferences, and to identify whether these individuals differ by demographic or health characteristics. Researchers conducted an adaptive conjoint analysis (ACA) using the Potentially All Pairwise RanKings of all possible Alternatives (PAPRIKA) method to determine preference weights representing the relative importance of six physical activity attributes: health benefit, enjoyment, convenience, financial cost, effort, and time cost. The study sample included 146 participants. The authors conclude that patients with chronic knee pain have preferences for physical activities which are effectively distinguished by using ACA methods, and that adults with chronic knee pain, as clustered by their preferences, share distinguishing characteristics.
