Survey outcomes (means with standard deviations). VAS = visual analogue score (scale 0–100). p values for one way ANOVA comparison between groups with post hoc Bonferroni correction for VAS and Fisher's Exact test for Have again and recommend. OA = osteoarthritis RA = inflammatory arthropathy (mainly rheumatoid arthritis), CTA = rotator cuff tear arthropathy, AVN = avascular necrosis.
