I would be interested to hear what the panel feels on the participant selection. Specifically the exclusion of patients in significant pain (a mean knee pain intensity in the previous week greater than 60 mm on a 100 mm visual analogue scale). For my practice the absence of severe pain is an exclusion criteria for surgery regardless of radiographic appearance.
Would the efficacy gap have widened if only patients with a VAS > 75mm had been included?
