Aim. MIS™ Quad-Sparing™ (MIS-QS) is a new technique that preserves the anatomic structures, specifically the knee extensor apparatus, that need to be protected to ensure rapid postoperative recovery of function and return to activities of normal daily living. The real advantages this new surgical technique offers were evaluated.
Methods. From June 2003 to May 2005, a knee prosthesis (NexGen CR, Zimmer) was placed in 52 patients with the MIS-QS technique and in 45 with conventional surgery. The two groups, which were similar in characteristics (age, sex, body-mass index, results of physical examination and preoperative radiography), were then compared to determine the possible advantages of the new technique. The procedures were compared by evaluating operating time, blood loss, functional recovery and implant precision of the components.
Results. The MIS-QS technique permitted faster and better recovery of function, less blood loss and less postoperative pain, without prolonging operating time and without diminishing implant precision.
Conclusion. Preliminary data suggest that the Mis-QS technique offers real advantages for smoother postoperative course and functional recovery.
