Yair D. Kissin, MD, Vice Chair of the Department of Orthopedic Surgery at Hackensack University Medical Center, and Assistant Clinical Professor at Hackensack Meridian School of Medicine, recently published a research paper in the peer-reviewed journal Surgical Technology International titled, “Active Robotic Total Knee Arthroplasty (TKA): Initial Experience with the TSolution One® TKA System.” The paper is based on a multi-center, prospective, non-randomized trial assessing the safety and effectiveness of TSolution One for total knee arthroplasty (TKA).

TSolution One is an active robotic device that supports an open implant platform and CT-based preoperative planning workflow, requiring minimal surgeon intervention for making bone cuts.

In a case study presented in the paper, surgeons used TSolution One to perform TKA on a 64-year-old male with severe osteoarthritis of the right knee.

The TSolution One provided several advantages during surgery. During the procedure, no medial soft-tissue release was needed to balance the knee. Additionally, due to bone loss on the femur, traditional cutting guides used in conventional TKA would not have had adequate bone to rest on, and therefore could have introduced error. The robotic surgical system was able to cut the bone precisely despite the bone loss.

In a second case study of a 72-year-old, active female, a severely arthritic left knee was indicated for robotic TKA. The patient had a successful robotic TKA with no need for lateral valgus soft tissue release or lateral patella release.

Dr. Kissin and his co-authors concluded that, although further studies are needed, the precision of robotic TKA could lead to fewer revisions, higher patient satisfaction, and improved efficiency.
