Actual (reported)Quadriceps-sparing minimally invasive total knee arthroplasty (TKA) with side-cutting instruments has been proposed to limit surgical dissection without compromising the surgical outcome. We conducted a prospective, randomized study to compare the outcomes of quadriceps-sparing TKA with conventional medial parapatellar TKA, with two-year follow-up. We hypothesize that the quadriceps-sparing arthrotomy would not outperform the conventional medial parapatellar arthrotomy in TKA, in terms of postoperative recovery of quadriceps muscle strength, alignment of the prosthetic knee, and clinical outcome.
