Effects of Blood Flow Restriction Combined With Electrostimulation After Knee Arthroplasty

The goal of this clinical trial is to learn whether blood flow restriction (BFR) combined with electrostimulation (ES) can improve the postoperative course of patients undergoing total knee arthroplasty. The main questions it aims to answer are: Immediately after surgery, do BFR combined with ES increase quadriceps strength? Do they also improve the functional abilities of patients? Researchers will compare BFR combined with ES to ES alone, to see if there are differences. Participants will carry out a daily session of BFR+ ES or ES alone for six working days after surgery
