Randomized Controlled TrialGait changes in patients with knee osteoarthritis are replicated by experimental knee pain.
Medial knee osteoarthritis (OA) is characterized by pain and associated with abnormal knee moments during walking. The relationship between knee OA pain and gait changes remains to be clarified, and a better understanding of this link could advance the treatment and prevention of disease progression. This study investigated changes in knee moments during walking following experimental knee pain in healthy volunteers, and whether these changes replicated the joint moments observed in medial knee OA patients. ⋯ In healthy subjects, pain was associated with reductions in knee joint moments during walking in a manner similar to less severe knee OA patients. The experimental model may be used to study mechanically-driven knee OA progression and preventive measures against abnormal joint loading in knee OA.

After patients are diagnosed with knee osteoarthritis, what do they do?
To learn more about the health services and products that patients use after receiving a diagnosis of knee osteoarthritis (OA), as well as the trajectory of their health-related quality of life (HRQOL). ⋯ Within 6 months of receiving a diagnosis of knee OA, participants made several lifestyle interventions, often without the advice of a health professional, and saw improvements in their pain and function.

Comparative StudyRisk of revision for infection in primary total hip and knee arthroplasty in patients with rheumatoid arthritis compared with osteoarthritis: a prospective, population-based study on 108,786 hip and knee joint arthroplasties from the Norwegian Arthroplasty Register.
To compare differences in the risk of revision for infection and changes in risk over time and in time from primary surgery to revision for infection after total hip replacement (THR) and total knee replacement (TKR) in rheumatoid arthritis (RA) and osteoarthritis (OA) patients. ⋯ The overall risk of revision for infection after TKR was higher in RA patients. The risk of late infection leading to revision of the TKR and THR was higher in RA patients than in OA patients. After the year 2000, the RR of revision for infection in RA compared with OA remained unchanged.
