Tourniquet vs. Short Time Tourniquet in Primary Robotic Assisted TKA

Is TKA With Short Tourniquet Time Superior to TKA With Tourniquet Use in Primary Robotic Assisted TKA? A Prospective, Randomized Study.

The goal of this prospective, randomized study is to compare the outcomes of patients undergoing Robotic Arm-Assisted TKA (RA-TKA) with the intraoperative use of a tourniquet to those undergoing RA-TKA with a short tourniquet time.

The goal of this prospective, randomized study is to compare the outcomes of patients undergoing Robotic Arm-Assisted TKA (RA-TKA) with the intraoperative use of a tourniquet to those undergoing RA-TKA with a short tourniquet time. The primary objectives will be to compare the total duration of hospital stay, quadriceps function, and the amount of postoperative narcotics utilized and VAS pain levels. The secondary objective will be to compare variables of patient functionality at five postoperative intervals.
