title: Cementless total knee arthroplasty in obese patients: a prospective matched study with follow-up of 5-10 years.
abstract: A prospective matched cohort study was performed to compare outcomes of cementless total knee arthroplasties between 171 knees in obese patients (BMI ≥ 30) and 171 non-obese patients (BMI < 30). Mean follow-up was 7 years. There were no significant differences in overall functional outcomes or components alignment. In the obese group, there were 14 perioperative complications, 9 revisions, and 5 other patients were considered clinical failures, whereas in the non-obese group there were 3, 5, and 7, respectively. There were no significant differences between obese class I-II and class III (morbid) subgroups. The obese and non-obese groups had similar implant survivorship at 7 years. Although TKA outcome in obese was satisfactory, these patients should be informed of the perioperative risks, and advised to lose weight prior to surgery.
