Primary Outcome Measures:
  • The main objective of this study is maximum overall pain in the knee during the week prior to the evaluation, measured by the Visual Analogue Scale 100mm. The basal score will be compared with the scoring obtained in each follow-up visit. [ Time Frame: 3 years and 4 months ] [ Designated as safety issue: No ]

Enrollment: 306
Study Start Date: October 2003
Study Completion Date: December 2009
Primary Completion Date: July 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: hyaluronic acid
Cycles of 5 injections of hyaluronic acid at specified intervals
Device: Hyaluronic acid
3 cycles of 5 hyaluronic acid injections, with a 6 month interval between each one. A 4th treatment cycle of five injections will be carried out at the end of one year
Placebo Comparator: Placebo
Cycles of 5 injections of saline at specified intervals
Other: Placebo
3 cycles of 5 saline solution injections, with a 6 month interval between each one. A 4th treatment cycle of five injections will be carried out at the end of one year

Detailed Description:
Superiority vs placebo of repeated cycles of hyaluronic acid intra-articularly administered wiht a follow up of more than 3 years. Safety of the intervention will be also monitored.
