    Bilateral total knee arthroplasty offers comparable outcomes to unilateral procedures, with similar pain relief and functional recovery. Careful patient selection is key for successful bilateral knee replacement surgery.

    Area of Science:

    • Orthopedic Surgery
    • Reconstructive Surgery

    Background:

    • Total knee arthroplasty (TKA) is a common procedure for knee joint arthritis.
    • Comparing bilateral (simultaneous) TKA with unilateral TKA is important for surgical decision-making.

    Purpose of the Study:

    • To compare postoperative results and complications between patients undergoing bilateral total knee arthroplasty and unilateral total knee replacement.

    Main Methods:

    • Retrospective comparison of 41 patients with bilateral TKA versus 40 patients with unilateral TKA.
    • Analysis of preoperative disability, postoperative range of motion, pain relief, need for walking aids, and complications.

    Main Results:

    • Both groups showed similar improvements in flexion contractures, pain relief, and reduced need for walking devices.

  • Unilateral TKA group had higher prosthetic loosening; bilateral TKA group had more wound problems and pulmonary emboli.
  • Rehabilitation, walking independence, and hospitalization duration were not significantly prolonged in the bilateral TKA group.

    • Conclusions:

    • Bilateral total knee arthroplasty is a reasonable option when indicated, offering comparable outcomes to staged unilateral procedures.
    • Careful patient selection and adherence to technical guidelines are crucial for optimizing bilateral TKA outcomes.
