WOMAC: Western Ontario and McMaster Osteoarthritis Index; ALF: Aggregated Locomotor Function. was considered statistically significant. Groups showed no significant differences at the baseline. Groups showed significant difference in all outcomes after two years. There was a significant difference in improvement over time between groups in all outcomes except for the ALF.
