Spa therapy with physical rehabilitation is an alternative to usual spa therapy protocol in symptomatic knee osteoarthritis.

The objective of the study was to demonstrate the non-inferiority of low-frequency spa therapy combined with rehabilitation (Spa-rehab) versus standard spa therapy at 6 months for symptomatic knee osteoarthritis (KOA). A prospective, randomized, monocenter, non-inferiority trial with recruitment of community-based symptomatic KOA patients was performed. Standard spa therapy comprised standardized spa treatment, 6 days a week for 3 weeks, and Spa-rehab therapy comprised spa sessions, 3 days a week for 3 weeks, followed by a dedicated rehabilitation program, 3 days a week for 3 weeks.
