To the Editor,
We read the article, “Obesity Does Not Imply Poor Outcomes in Asians after Total Knee Arthroplasty” by Bin Abd Razak et al.  with great interest. We believe the results of this study will add to the orthopaedic literature on TKA.
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  and 3 , 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 , mean ROM changes at 2-year are given as −2°, −1°, −1°, +10° for normal, overweight, obese, and severely obese patient groups. However, calculations relative to Tables 2 and 3 yield −1°, 0°, 0° and +10°.
Additionally, in Table 5 , the preoperative and postoperative values at 2-year followup for severely obese patient groups in the “Current Study” are 100°–100°, respectively. This would indicate no change of ROM for severely obese patients.
