“…The extensor mechanism suffers less damage and the patella is not everted in a MIS TKA, which would result in good patellar tracking and lower incidence of anterior knee pain. However, the literature shows only early recovery and less postoperative pain in patients who have had MIS TKAs [4,14,28], but does clarify the incidence of patellar maltracking or the development of anterior knee pain. Additionally, it is unclear whether the incidence of patellar maltracking or anterior knee pain differ with the MPP or MV approach in MIS TKAs.…”

Background Since the medial parapatellar (MPP) approach in conventional TKA can cause patellar maltracking and anterior knee pain, some orthopaedic surgeons use the midvastus (MV) approach instead of the MPP approach to reduce patellar maltracking. Minimally invasive surgical (MIS) TKA has been developed to limit the damage to the surrounding muscle and reduce the necessity of patellar eversion during surgery. Thus, MIS TKA might be associated with proper patellar tracking and a low incidence of anterior knee pain. However, this presumption has not been confirmed. Questions/purposes We asked whether the incidence of patellar maltracking and anterior knee pain differed with the MV and MPP in association with MIS TKA. Methods We prospectively followed 59 patients (60 knees)

“…It was believed to reduce hospitalization time [4,28], increase ROM [14,28], reduce pain [4,14], and more rapidly restore function [4]. In addition, if the quadriceps in the MPP approach is cut no more than 2 cm above the superior pole of the patella, the quadriceps recovers more rapidly [6,27].…”

“…If similar variability is observed in our patients, then a sample of 15 subjects in each study group (30 subjects total), will provide 80% power (a = 0.05) to detect a difference of 5 days [19]. For ROM, Laskin et al [10] reported a standard deviation of 12°in a cohort of patients undergoing unilateral MIS-TKA. If similar variability is observed in our patients, then a sample of 15 subjects in each study group (30 subjects total) will provide 80% power (a = 0.05) to detect a difference of 10 o [10].…”

“…Minimally invasive TKA also may reduce blood loss and the incidence of hemodynamic complications by limiting the amount of soft tissue disruption over conventional TKA [10,13,[18][19][20]. However, prolonged operative time and limited exposure in MIS-TKA may increase the risk of perioperative complications such as thromboembolic complications and malpositioning of the components [1,7,19].…”

Simultaneous bilateral TKAs subject patients to more arduous and painful functional recovery and increased risk of hemodynamic complications than staged bilateral TKAs. Minimally invasive TKA (MIS-TKA) reportedly results in more rapid return of function by limiting the amount of soft tissue disruption. We asked whether bilateral MIS-TKA had advantages over conventional TKA with respect to faster functional recovery. We prospectively randomized 30 patients into an MIS group (mini-medial parapatellar approach, 15 patients) and a conventional group (conventional medial parapatellar approach, 15 patients). We recorded range of motion and the time required to regain the ability to walk without assistance. Functional recovery in the MIS group was faster in rehabilitation milestones of walking without assistance and gain in range of motion. Minimally invasive TKA may benefit patients undergoing simultaneous bilateral procedures with faster functional recovery. Level of Evidence: Level II, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.
