No significant difference in clinical outcomes found in simultaneous bilateral TKA (Healio)
Patients who underwent simultaneous bilateral total knee arthroplasty experienced no significant differences in clinical outcomes, according to study results.
Researchers retrospectively reviewed 420 consecutive patients who underwent simultaneous bilateral total knee arthroplasties (TKAs) between January 2011 and April 2012. Postoperative blood loss, operation time, implanted femoral and tibial component size, and perioperative surgical complications were compared between the bilateral sides. The researchers recorded range of motion in all patients at 1 month preoperatively and 1 year postoperatively, and clinical outcome scores were measured using Knee Society Knee Score (KSKS), Knee Society Function Score (KSFS) and WOMAC scores preoperatively and at 1 year after surgery.
Compared with the first TKA, results showed a greater incidence of outliers during postoperative coronal limb alignment for the second TKA, with mean coronal alignment values of 1.1° for the first TKA vs. 1.9° in the second TKA. The researchers found no identical outcomes between the second and first TKA, including opera...
