Robotic system for TKA requires simple and complex workflow adaptations

KOLOA, Hawaii — Use of a robotic system for total knee arthroplasty requires simple and complex adaptations to workflow compared with conventional instruments, according to a presenter at Orthopedics Today Hawaii.
In his presentation, Brad L. Penenberg, MD, noted some of the simple adaptations of the Navio Surgical System (Smith & Nephew) include use of a burr, which he questioned as either an upgrade or a necessary evil. Room and OR table setup also need to be taken into consideration. Penenberg recommended surgeons stay on one side of the OR table and not block the arrays.
“Among the more complex adaptations, if you are changing knee implant systems, you have to take a close look at what you are changing to and what you have been doing,” Penenberg said.
He added the Navio Surgical System does not protect the posterior cruciate ligament, requiring surgeons to make adaptations to retain it. The planning screens will also not alert surgeons on whether the patient needs to undergo a release or whether femoral rotation is ideal for a particular patient, according to Penenberg.
“This was one of the surprises for me — that there are no boundaries as you are going through your decision-making process,” Penenberg said.
Penenberg noted surgeons should have a clear idea of the technique they want to use and be prepared to modify or adapt it.
“One of the most important things I was told during the trainings: When you turn on the robot, do not turn off your brain,” Penenberg said. “Unlike one of the other systems on the market, you cannot just set it and forget it. You have to participate with the technique.” – by Casey Tingle
