“…In a cross-sectional analysis, Sanchez-Santos et al 37 reported that a smaller percentage of adults at least 5 years after RYGB (22% [50]) had difficulty with mobility when compared with controls matched on presurgery characteristics (55%; P < .01). Likewise, Raoof et al 38 reported that mean (SD) scores for bodily pain and physical function on the SF-36 were better 12 (3) years post-RYGB when compared with those of morbidly obese controls who were awaiting surgery (matched on age and sex). Another study, 39 which provided follow-up for 145 LAGB patients for 3 to 8 years, reported that fewer patients had significant knee pain at follow-up vs baseline (38% vs 47%; P < .01).…”
