title: Intra-articular corticosteroids. An updated assessment.
abstract: Local corticosteroid injections are a relatively safe and effective adjunct in managing rheumatoid arthritis, other connective tissue arthropathies, and soft tissue rheumatism. Rheumatoid synovitis may be suppressed for three months or longer using relatively insoluble microcrystalline preparations. No convincing evidence exists, however, that joint erosive changes are retarded, and steroid injections should be considered ancillary to rest, physical therapy, nonsteroidal anti-inflammatory agents, and disease modifying antirheumatic drugs. The few controlled studies in hip and knee osteoarthritis have demonstrated only modest, fleeting beneficial effects. Nonetheless, clinical experience suggests that intra-articular steroids often ameliorate acute exacerbations of knee osteoarthritis associated with significant effusions, symptomatic involvement of interphalangeal and other nonweight-bearing articulations, synovial cysts, and lumbar facet arthropathy. Judicious use of intrasynovial injections seldom produces significant adverse effects. Iatrogenic infectious arthritis follows one in 14,000-50,000 injections. Rapid acceleration of cartilage attrition is observed rarely. The concept of "corticosteroid arthropathy" is based largely on subprimate animal studies and several anecdotal case reports; limited investigation of primate (monkey) models has shown no significant long-term deleterious effect on cartilage.
