“…We found no other patellofemoral complications such as patellar clunk, patellar crepitation, and fractures. The literature however reports patellar crepitation ranging from 0% to 13.5% [19,23]. Although both techniques of MIS TKA did not result in a stiff knee or the need for manipulation later in our patients, the literature reports 2% to 13.5% rates of manipulation [7,18,21,25,34].…”

“…The MPP group with conventional TKAs reportedly has a tilt angle of 0.8°to 8.4°a nd subluxation of 1.5 mm [11,19,20,22]. The MPP approach had a tilt angle of 3.198 to 5.388 [22].…”

“…All patients experienced mild occasional pain. Previous studies showed the incidence of anterior knee pain after conventional TKAs with patellar resurfacing varying from 5.3% to 21.0% of patients (Table 5) [2,3,5,19,30,32], and the VAS score for anterior knee pain range from mild to moderate pain [2,19,30].…”

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)

“…43 However, patellofemoral complications are different in cementless patellar resurfacing. Whereas most cementless TKA procedures incorporate cementless femoral and tibial component fixation with cemented all-polyethylene buttons, some make use of a metal-backed component that is either fixed to the polyethylene articular surface or permits rotation of a polyethylene bearing that is a snap-fit onto the metal prosthesis.…”

There has been a recent increase in interest for non-cemented fixation in total knee arthroplasty (TKA), however the superiority of cement fixation is an ongoing debate. Whereas the results based on Level III and IV evidence show similar survivorship rates between the two types of fixation, Level I and II evidence strongly support cemented fixation. United Kingdom, Australia, Sweden, and New Zealand registry data show lower failure rates and greater usage of cemented than non-cemented fixation. Case series studies have also indicated greater functional outcomes and lower revision rates among cemented TKAs. Non-cemented fixation involves more patellofemoral complications, including increased susceptibility to wear due to a thinner polyethylene bearing on the cementless metal-backed component. The combination of results from registry data, prospective randomised studies, and meta-analyses support the current superiority of cemented fixation in TKAs.

“…Patella was prepared using the Ranawat technique. 7 The medial facet was excised using an oscillating saw starting from inferior pole of the patella followed by excision of the articular surface of the lateral facet of the patella to the depth of the subchondral bone. The medial facet was excised parallel to the anterior surface.…”
