Utility and feasibility of musculoskeletal ultrasonography (MSK US) in rheumatology practice in Canada: needs assessment.

The utility of musculoskeletal ultrasound (MSK US) is being extensively explored and evaluated amongst European rheumatologists. However, utilization of MSK US by rheumatologists in Canada is much less common. This study aimed to evaluate the current use of MSK US in Canadian rheumatology practice, to determine beliefs and attitudes towards MSK US, and to determine factors that may encourage or limit its use.

Safety and efficacy of long-term intraarticular steroid injections in osteoarthritis of the knee: a randomized, double-blind, placebo-controlled trial.

Objective: To evaluate the safety and efficacy of long-term intraarticular (IA) steroid injections for knee pain related to osteoarthritis (OA).

Methods: In a randomized, double-blind trial, 68 patients with OA of the knee received IA injections of triamcinolone acetonide 40 mg (34 patients) or saline (34 patients) into the study knee every 3 months for up to 2 years. The primary outcome variable was radiologic progression of joint space narrowing of the injected knee after 2 years.
