Robotically-Assisted Unicompartmental Knee Arthroplasty with a Hand-Held Image-Free Sculpting Tool

Unicompartmental arthroplasty (UKA) is a successful procedure for the treatment of focal arthritis or osteonecrosis of the medial or lateral compartments of the knee. While UKA may pose lower risk of perioperative complications and achieve better functional outcomes than TKA, a high degree of accuracy of implant positioning and soft tissue balance are required to optimize durability and implant survivorship. First generation robotic technology improved substantially implant position compared to conventional methods; however, high capital costs, uncertainty regarding the value of advanced technologies, and the need for preoperative CT scans were barriers to broader adoption.
