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.

Ethnicity, cortisol, and experimental pain responses among persons with symptomatic knee osteoarthritis.
This study aimed to examine the relationship between cortisol and pain responses during a cold-pressor task (CPT) among African American (AA) and non-Hispanic White (NHW) adults with knee osteoarthritis (OA). Consistent with previous findings in young healthy adults, cold-pressor pain responses are related to pre-CPT cortisol concentrations in NHW persons with knee OA but not in their AA counterparts.

Functional gain and pain relief after total joint replacement according to obesity status.
The researchers examined the changes between preoperative and postoperative function and pain in a large representative U.S. cohort to determine if there was a relationship to obesity status. They found that six months after total joint replacement, severely or morbidly obese patients reported excellent pain relief and substantial functional gain that was similar to the findings in other patients.

Important patient characteristics differ prior to total knee arthroplasty and total hip arthroplasty between Switzerland and the United States.
The researchers compared preoperative patient and clinical characteristics from two large cohorts who underwent either total knee (TKA) or hip (THA) arthroplasty, one in Switzerland, the other in the US. They found substantial differences between US and Swiss cohorts in pre-operative patient characteristics and pain levels, which has potentially important implications for cross-cultural comparison of TKA/THA outcomes.

Preoperative pain and function: profiles of patients selected for total knee arthroplasty.
The researchers examined patient-reported preoperative pain and function profiles to understand symptom severity at the time of total knee arthroplasty (TKA) decision. Of 6,936 patients, 77 percent had high pain and poor function (group 4), 19 percent had high pain "or" poor function (groups 2-3), and 5 percent had little pain and high function before TKA (group 1).

Consensus on the need for a hierarchical list of patient-reported pain Outcomes for Metaanalyses of Knee Osteoarthritis Trials: An OMERACT Objective.
A group of international experts convened to address issues regarding the need to develop hierarchical lists of outcome measurement instruments for a particular outcome for metaanalyses. After discussions, most participants agreed that there is a need to develop a methodology for generation of hierarchical lists of outcome measurement instruments to guide metaanalyses.
