The efficacy, accuracy and complications of corticosteroid injections of the knee joint
Knee Surgery, Sports Traumatology, Arthroscopy, 01/17/2011
McGarry JG et al. – Short–term symptomatic relief is the only evidence–based benefit of corticosteroid injection of an osteoarthritic knee. Accurate intra–articular placement is not achieved in up to 20% of injections and varies considerably with the anatomical approach used. There is no evidence that a medial approach is more accurate. The incidence of serious infectious complications following knee joint injections ranges widely, and may be as high as 1 in 3,000 and potentially far higher in high–risk patients for whom specialist management is advised.
