Razzaki T, et al. - Researchers undertook this inquiry in the Asian cohort of consecutive patients who received total knee arthroplasty (TKA) from 2004 to 2015, to assess weight change patterns as well as their influences on clinical results post-TKA in this prospective cohort study, hypothesizing a distinct pattern of weight change post-TKA in Asian patients vs Western patients, and better clinical outcomes in relation to weight loss post-TKA. A conventional posterior-stabilized TKA implant was received by all patients. Participants also underwent a standard perioperative care pathway. Prior to surgery, at 6 months, and 2 years following surgery, evaluations were carried out. Overall 602 patients (602 knees) were examined, with mean age of 66.39 ± 7.27 years and a mean BMI of 27.75 ± 4.51 kg/m². Post-TKA weight gain was reported in 63.12% of patients. Findings revealed a tendency of gaining weight after TKA in Asians. However, there was no influence of this weight change post-TKA on clinical outcomes, which continued to be good across all BMI groups.
