Is Clinical Outcome of Robotic-Assisted TKA Better Than Conventional Manual TKA?Prospective, Randomized Study
In Brief
A Phase 4 clinical trial evaluating Robotic-assisted TKA and Conventional TKA for Arthritis and 2 related conditions. Completed, enrolled 674 participants.
Detailed Summary
Robotic-assisted total knee arthroplasty (TKA) was introduced to attempt to enhance the precision of bone preparation, component alignment and ultimately improve clinical results and survivorship of TKA. Although several published data suggest that bone preparation, and knee component alignment were improved by using robotic assistance, there is no high-quality evidence from randomized trials at long-term of which investigators are aware evaluating whether the improved bone preparation and knee component alignment improved clinical function or longevity of the TKA.

Timeline
Interventions
Total knee arthroplasty is carried out with help of robotic surgery system, using a Robodoc system. CT-based preoperative planning using ORTHODOC (Integrated Surgical Technology Corp) performed in the first step before the day of surgery, and the robotic-assisted surgery using the ROBODOC surgical assistance in the second step. The bone markers are registered to the computer, and the computer arm does all the cutting and preparation of bones. This is in contrast to conventional jigs and cutting blocks. Actual implantation of the implants is done by a surgeon. A Duracon posterior cruciate-substituting total knee prosthesis (Stryker Orthopedics, Mahawh, NJ, USA) are used in all knees.
Total knee arthroplasty is carried out with classical, conventional, manual method. A surgeon measures the angle, length of the cuts with bone landmarks and specialized surgical instruments. After all the cuts actual implantation is done. A Duracon posterior cruciate-substituting total knee prosthesis (Stryker Orthopedics, Mahawh, NJ, USA) are used in all knees.
