Yong TM, et al. - In this retrospective review, researchers focused on long-term implant survivorship and modes of failure in simultaneous concurrent bilateral total knee arthroplasty (TKA). They reviewed medical records for preoperative features, perioperative complications, and revision surgeries from 266 consecutive patients (532 knees) who had simultaneous concurrent bilateral TKA. Participants were observed over a median duration of 9.8 years. A revision was performed on 44 patients (17%) and was more common among younger and male patients. A higher risk of reoperation was reported in correlation with simultaneous concurrent bilateral TKA when both knees were evaluated but the evaluation of each knee in isolation revealed similar implant survivorship to the literature.
