Quadriceps Sparing Total Knee Arthroplasty

Are There Any Clinical and Radiographic Differences Between Quadriceps-sparing and Mini-medial Parapatellar Approaches in Total Knee Arthroplasty After a Minimum 5 Years of Follow-up?

“…[ 19 ] Tenholder et al [ 6 ] reported that TKA performed using the MMP approach was associated with the lesser need for blood transfusion and better flexion in the perioperative period, as compared to TKA with the traditional approach. On the other hand, Tria and Coon[ 8 ] reported that considering its favorable early outcomes, the m-QS technique for TKA appears to be promising. More recently, a randomized controlled study revealed that patients undergoing TKA with the MIS approach showed early recovery of strength.…”

“…The approach used in this study was not exactly identical to the one described by Tria and Coon. [ 8 ] MIS QS instruments (Zimmer) were used. First, patellar resection was performed, and the metal patellar protector was used to avoid the pressing of the bone-cutting surface by the patellar retractor.…”

“…Various minimally invasive surgery (MIS) techniques for TKA have been developed and improved with a view to enhancing postoperative functional recovery by preserving the function of the extensor mechanism and improving overall patient satisfaction. [ 4 5 ] The MIS approaches developed thus far are the mini-medial parapatellar (MMP),[ 6 ] mini-midvastus,[ 7 ] quadriceps-sparing (QS),[ 8 ] mini-subvastus, and minimally invasive lateral[ 9 ] approaches.…”

“…[ 14 15 ] Although a few prospective randomized studies have compared both the approaches, neither of them has been established as the superior one; furthermore, most of these studies were based on follow-up for only 2 years. [ 8 16 ] Apparently, more long-term studies are necessary to identify the better approach.…”
