  1. Pearson’s correlations were used for normally distributed variables, aSpearman’s correlations for those that were non-parametric. DASS: Depression Anxiety Stress Scales- 0 = best, 42 = worst. AQoL: Assessment of Quality of Life Instrument- Standardised scores- 0 = worst, 100 = best. KOOS: Knee injury and Osteoarthritis Outcome Score- 0 = worst, 100 = best. HOOS: Hip disability and Osteoarthritis Outcome Score- 0 = worst, 100 = best.
