Abstract
A force-sensing joint tensioner assembly, surgical system, and method of use is provided. The joint tensioner assembly can include a housing that is configured to receive a fluid from a pump and a movable member that is configured to translate relative to the housing as the fluid is pumped into the housing. The tensioner and/or a surgical system including the tensioner can further include a pressure sensor configured to sense a pressure exerted by the movable member as the movable member translates and distracts the patient's joint. A surgical computer system can be configured to determine a distraction distance of the joint according to a volume of the fluid pumped into the joint tensioner assembly by the pump and/or determine a pressure exerted by the movable member according to the pressure sensor.
