I was in the business 20 years ago, pick the surgeon who does the most knees, he's likely the best. Knees require varying degrees of soft tissue balancing to restore pain free function and ensure implant longevity. I doubt there's a robot for that
The PCL is what keeps your femur from sliding off your tibia when you descend stairs. Since your PCL is torn, you'll likely require a posterior stabilized implant. Back in the day, HSS (NY) was one of the few centers that routinely used PS implants for primary cases. Back then, the Zimmer Insall Burstein implant had the longest/best track record, due in no small part to the surgeons that advocated it and did a ton of them. Posterior stabilized implants require a larger femoral resection to accommodate the "box" that corresponds to an elevated spine on the tibial insert that replaces the PCL.
Find a surgeon that routinely sacrifices the PCL, they will likely serve you best. Good Luck!
