Multicenter StudyImpact of physician specialty on classification of physician-perceived patient severity for patients with osteoarthritis.
Physicians often classify patients' osteoarthritis (OA) severity subjectively. As treatment decisions are influenced by severity classifications, it is important to understand the factors that influence physicians' OA severity ratings. This research sought to empirically identify physician and patient characteristics that lead to a patient being perceived as having more severe OA. ⋯ Patient age, BMI, presence and severity of symptoms and health care use significantly impacted physicians' OA severity ratings, but radiographic changes appeared to be given greater weight among orthopedic surgeons and rheumatologists than PCPs when assessing patient severity. Whether these differences translate into different treatment recommendations for similar patients is unknown, and warrants study.

Multicenter StudyTrajectories and risk profiles of pain in persons with radiographic, symptomatic knee osteoarthritis: data from the osteoarthritis initiative.
Little is known about the temporal evolution of pain severity in persons with knee osteoarthritis (OA). We sought to describe the pain trajectory over 6 years in a cohort of subjects with radiographic, symptomatic knee OA. ⋯ We found that knee pain changes little, on average, over 6 years in most subjects. These observations suggest knee OA is characterized by persistent rather than inexorably worsening symptoms.

Multicenter StudyAssociation between fixation technique and revision risk in total hip arthroplasty patients younger than 55 years of age. Results from the Nordic Arthroplasty Register Association.
To evaluate implant survival following primary total hip replacement (THR) in younger patients. To describe the diversity in use of cup-stem implant combinations. ⋯ Uncemented implants perform better in relation to long-term risk of aseptic loosening, whereas both uncemented and hybrid rather than cemented implants in patients younger than 55 years had more short-term revisions because problems due to dislocation, periprosthetic fracture and infection has not yet been completely solved. The vast majority of cup-stem combinations were used in very few operations.
