Association of preoperative opioid use with mortality and short-term safety outcomes after total knee replacement.
The purpose of this study was to determine the association of preoperative opioid use among patients 65 years and older with mortality and other complications at 30 days post-total knee replacement (TKR). Findings show that continuous opioid users had a higher risk of revision operations, vertebral fractures, and opioid overdose at 30 days post-TKR but not of in-hospital or 30-day mortality, compared with opioid-naive patients. Highlights include the need for better understanding of patient characteristics associated with chronic opioid use to optimize preoperative assessment of overall risk after TKR.

A 12-item short form of the Hip disability and Osteoarthritis Outcome Score (HOOS-12): tests of reliability, validity and responsiveness.
The goal of this study was to measure validity, reliability and responsiveness of the 12-item version of the 40-item Hip disability and Osteoarthritis Outcome Score (HOOS) surveys that measure joint-specific pain, function and quality of life (QOL) for patients. The shorter forms were given to 1,281 hip OA patients from the FORCE-TJR cohort who had previously completed the HOOS surveys before and after total joint replacement surgery. The HOOS-12 survey was compared to the full-length HOOS, HOOS-PS, and HOOS, JR surveys. Internal consistency reliability was above 0.70 for all HOOS-12 scales and above 0.90 for the Summary score. Validity and responsiveness were also found to be comparable to full-length HOOS scales.

Item selection for 12-item short forms of the Knee injury and Osteoarthritis Outcome Score (KOOS-12) and Hip disability and Osteoarthritis Outcome Score (HOOS-12).
The goal of this study was to develop 12-item versions of the 42-item Knee injury and Osteoarthritis Outcome Score (KOOS) and 40-item Hip disability and Osteoarthritis Outcome Score (HOOS) surveys that measure joint-specific pain, function and quality of life (QOL) for patients. The shorter forms were given to 1,395 knee osteoarthritis (OA) and 1,281 hip OA patients from the FORCE-TJR cohort who had previously completed the KOOS and HOOS surveys before and after total joint replacement surgery. The KOOS-12 and HOOS-12 surveys were found to successfully measure pain and function items of the patients as well as the 42-item versions.

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.

Living in immigrant communities does not impact total knee arthroplasty outcomes: experience from a high-volume center in the United States.
The objective of this study was to assess the relationship of neighborhood immigrant proportion (IP) to preoperative and 2-year postoperative pain and function after elective total knee arthroplasty (TKA) using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Patients in a high-volume institutional TKA registry were analyzed retrospectively, and demographics, pre-op and 2-year post-op WOMAC pain and function scores, and addresses obtained. Patient-level variables were linked to Census Bureau tract data. Researchers conclude that patients living in high IP neighborhoods do not have worse pre-op or 2-year post-op pain and function outcomes after TKA compared to those living in lower IP neighborhoods.

Patients less likely to lose weight following a knee replacement: results from the osteoarthritis initiative.
The purpose of this study was to examine weight change patterns preoperatively and postoperatively among overweight/obese knee replacement patients. Overweight and obese patients initially lost weight during the interval including knee replacement; however, they were less likely to lose more than 2.5% of their weight in the 1 to 2 years immediately after the surgery.

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.

Validity and responsiveness of the knee injury and osteoarthritis outcome score: a comparative study among total knee replacement patients.
The researchers evaluated validity and responsiveness of the Knee Injury and Osteoarthritis Outcome Score (KOOS) in relation to other patient-reported outcome measures before and after total knee replacement (TKR). They concluded that KOOS scales were valid and responsive in a cohort of 1,143 US TKR patients. KOOS QOL performed particularly well in capturing aggregate knee-specific outcomes.

Biologics or tofacitinib for people with rheumatoid arthritis naive to methotrexate: a systematic review and network meta-analysis.
The researchers performed a systematic review to compare the benefits and harms of biologics and small molecule tofacitinib versus comparator (methotrexate (MTX) and other disease-modifying antirheumatic drugs) in patients with rheumatoid arthritis (RA) who are naive to methotrexate. They concluded that in MTX-naive RA participants, there was moderate-quality evidence that, compared with MTX alone, biologics with MTX were associated with absolute and relative clinically meaningful benefits in three of the efficacy outcomes.

Biologics or tofacitinib for people with rheumatoid arthritis unsuccessfully treated with biologics: a systematic review and network meta-analysis.
This review is focused on biologic or tofacitinib therapy in people with rheumatoid arthritis (RA) who had previously been treated unsuccessfully with biologics. Biologic (with or without methotrexate (MTX)) or tofacitinib (with MTX) use was associated with clinically meaningful and statistically significant benefits compared to placebo or an active comparator (MTX/other traditional disease-modifying anti-rheumatic drugs) among people with RA previously unsuccessfully treated with biologics.

The clinical status and economic savings associated with remission among patients with rheumatoid arthritis: leveraging linked registry and claims data for synergistic insights.
Treat to target guidelines recommend achieving remission or low disease activity in rheumatoid arthritis (RA). However, the reduction in adverse events and costs associated with lower disease activity is unclear. This study found that leveraging the benefits of linking registry and administrative data together, lower disease activity in RA was associated with incrementally reduced risks of all-cause hospitalization, ED visits, mortality, and medical costs in a dose-dependent fashion.

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.
