BackgroundLimited data have been published regarding the typical coronal dimensions of the femur and tibia and how they relate to each other. This can be used to aid in judging optimal operative reduction of tibial plateau fractures. The purpose of the present study was to quantify the width of tibial plateau in relation to the distal femur.MethodsWe reviewed 3D computed tomography (CT) scans taken between 2013 and 2016 of 42 patients (84 knees). We measured positions of the lateral tibial condyle with respect to the lateral femoral condyle (dLC) and the medial tibial condyle with respect to the medial femoral condyle (dMC) in the coronal plane. Positions of the articular edges of the lateral and medial tibia were also measured with respect to the femur (dLA and dMA).ResultsThe mean (± standard deviation) measurements were as follows: dLC, − 0.1 ± 1.9 mm; dMC, − 4.7 ± 4.1 mm; dLA, 0.9 ± 1.0 mm; and dMA, 0.1 ± 1.5 mm. The mean (± standard deviation) ratio of tibial to femoral condylar width was 0.91 ± 0.03, and the ratio of tibial to femoral articular width was 1.01 ± 0.04.ConclusionsThe articular width of the tibia laterally and medially was slightly wider than the femoral articular width. These small differences and deviations indicate that the femur might be used as a reference to judge tibial plateau width reduction.

“…There have been several reports that simulated the relationship between malrotation and coverage in a computer model using CT or MRI reconstructions in other types of total knee prostheses. [7][8][9][10][11][12] However, those reports did not investigate the TKA candidates 7,8,[10][11][12] or placed the tibial component in the center of the tibial bone cut surface, [9][10][11][12] although surgeons usually set the tibial component anteriorly and laterally. In this study, we investigated the coverage of the tibial component during TKA and set the tibial component anteriorly and laterally.…”

“…6 For a conventional symmetric tibial component, the tibial rotation parallel to the anteroposterior (AP) axis results in insufficient coverage of posteromedial part and the sufficient coverage of tibial surface results in internal rotation of the tibial component because morphologically the medial tibial plateau tends to be larger than lateral tibial plateau. [7][8][9] Therefore, tibial rotation parallel to the AP axis and sufficient coverage of the tibial surface might conflict.…”

Asymmetric Tibial Component Improved the Coverage and Rotation of the Tibial Component in a Medial Pivot Total Knee Prosthesis

Malrotation of tibial components is one of the important causes of failure in total knee arthroplasty. The aim of this study is to determine the relationship between tibial rotational positioning and coverage of the tibial surface during the operation, using a symmetric and newly introduced asymmetric medial pivot tibial components. The coverage and overhang were compared between a symmetric component (Advance medial pivot) and a newly introduced asymmetric medial pivot tibial component (Evolution medial pivot) in 31 knees during the operation. When the tibial component was placed parallel to the anteroposterior (AP) axis, the uncovered width in the posteromedial part using a symmetric design was larger than that using an asymmetric design ( < 0.01). Overhang in the posterolateral part was observed in 42% for a symmetric design and 3% for an asymmetric design ( < 0.01). When the component was placed in malrotation (10 degrees internal to the AP axis), overhang in the posteromedial part was observed in 6% for a symmetric design and in 71% for an asymmetric design ( < 0.01). The tibial rotation parallel to the AP axis and maximizing coverage of the tibial surface conflict in a symmetric design, but are compatible in an asymmetric design. An asymmetric tibial component is expected to improve the coverage and the rotational positioning of medial pivot total knee prosthesis.

“…It was therefore not possible for him to evaluate the positioning of the implant, to locate the overhang and to measure its size. Asymmetry of the proximal tibia has been described by many authors [47][48][49][50]. It is thus difficult to insure bone coverage with a symmetrical implant in patients with asymmetrical tibial plateau.…”
