Multicenter Study Comparative StudyTotal hip or knee replacement for osteoarthritis: mid- and long-term quality of life.
To compare quality of life (QOL) scores 3 and 10 years after total hip arthroplasty (THA) or total knee arthroplasty (TKA) for osteoarthritis with QOL scores in a general population, and to determine factors associated with QOL after surgery. ⋯ THA or TKA can improve QOL, but the benefits may be time limited. Addressing environmental factors and treating comorbidities and pain in locations other than the arthroplasty location could have mid- and long-term effects on the QOL of patients with THA or TKA.

Comparative StudyMagnetic resonance imaging grading system for active and chronic spondylarthritis changes in the sacroiliac joint.
To develop a new grading method to quantify activity and chronic spondylarthritis (SpA) changes in the sacroiliac (SI) joints identified by magnetic resonance imaging (MRI), taking into account the complex joint anatomy, and to compare the findings with radiographic changes. ⋯ Separate assessment of the ligamentous joint portion by MRI may be valuable for differentiating AS from nonprimary AS forms of SpA. Erosive changes on MRI were significantly related to radiographic changes, implying a possibility for substituting radiography with MRI.
