Abstract Background In Asia, obesity has reached epidemic proportions and physicians are
likely to face a burden of obesity-related disorders, of which osteoarthritis of the knee is one.
However, it is unclear whether obesity affects improvement of conventional TKAs in Asian
patients. Purpose We therefore asked whether obese patients with a BMI of 30 kg/m 2 or
greater would have worse ROM and function after TKA compared with their nonobese
counterparts and whether they would have less improvement preoperatively to …

However, when we looked at the tables in detail, we detected some conflicts or printing
errors which we believe need correction and/or explanation. In Tables 2 [1] and 3 [1], the
preoperative and postoperative ROM values are given for each group. The preoperative and
postoperative ROM values at 2-year followup for normal, overweight, obese, and severely
obese patient groups are 119–118, 119–119, 116–116 and 100–110, respectively. In Table
4 [1], mean ROM changes at 2-year are given as À2, À1, À1,+ 10 for normal, overweight …
