advantages to patients undergoing partial knee arthroplasty, total
knee and hip arthroplasty by providing the surgeon with real time
intraoperative numerical information on overall limb and implant
alignment, soft tissue balancing within 1 mm, accurate bone cuts and
reduced iatrogenic soft tissue injury seen with manual instruments
and saws. The robotic-assisted arm allows the surgeon to make
bone cuts within the boundaries established by the 3D CT based
preoperative plan therefore minimizing any iatrogenic soft tissue
injury. Innovation in computer technology along with roboticassisted
surgery has provided orthopedic surgeons with virtual 3D
preoperative planning to improve decision making on the desired
target alignment for the individual patient, real time information
on a computer screen to allow for any intraoperative adjustments,
decreased soft tissue trauma and improved patient satisfaction and
outcomes. As advances in technology continue to evolve in the field
of orthopaedics, randomized studies and long-term data are required
to demonstrate the efficacy of these new innovative technologies
using robotic-assisted surgery in total joint arthroplasty.
