title: Current role of glucosamine in the treatment of osteoarthritis.
abstract: OBJECTIVE
  To evaluate the interest of using the various preparations of glucosamine for symptomatic and structural management of osteoarthritis (OA).
  
  
  METHODS
  A critical analysis of the literature based on an exhaustive search (Medline, PubMed and manual search within the bibliography of retrieved manuscripts) from 1980 to 2005.
  
  
  RESULTS
  Despite multiple controlled clinical trials of the use of glucosamine in OA (mainly of the knee), controversy on efficacy related to symptomatic improvement continues. Differences in results originate from the differences in products, study design and study populations. Symptomatic efficacy described in multiple studies performed with glucosamine sulphate (GS) support continued consideration in the OA therapeutic armamentarium. The most compelling evidence of a potential for inhibiting the progression of OA is also obtain with GS.
  
  
  CONCLUSIONS
  GS has shown positive effects on symptomatic and structural outcomes of knee OA. These results should not be extrapolated to other glucosamine salts [hydrochloride or preparations (over-the-counter or food supplements)] in which no warranty exists about content, pharmacokinetics and pharmacodynamics of the tablets.
