“…Hernandez-Vaquero and his team in 2018 measured the tibial torsion angle before and after knee replacement to reveal if knee replacement could lessen torsion of the tibia. They found that joint replacement can lessen tibial torsion by approximately 2° (from 17.76° to 15.36° on average) but cannot cancel it [ 7 ]. Mizu-uchi et al in 2006 studied the effect of ankle joint rotation on the tibia cut using the extramedullary cutting guide.…”

The alignment of tibial component in total knee replacement operation must be achieved in three planes to ensure optimum results. In coronal plane, the alignment depends on three anatomical landmarks. These landmarks are tibial tuberosity, leg shin, and midtalar point. In eastern community, people get used to sit cross-legged which causes additional tension in the quadriceps muscle which is attached distally to the tibial tuberosity. This tension causes adaptation of the tuberosity laterally. Tuberosity adaptation causes the three anatomical landmarks being not collinear. In this work, eight cases of lateral adapted tubercle were diagnosed of this condition before the surgery and their X-ray images after the surgery were checked regarding tibial alignment. Tibial alignment has been checked by measuring the medial proximal tibial angle (MPTA) which is the angle between the mechanical tibial axis and the tibial component plateau. MPTAs for the eight cases were (86.9°–93.6°). Three cases had MPTA less than 90° indicating varus alignment and five of them had MPTA more than 90° indicating valgus alignment. A geometrical tool was designed using the DesignSpark Mechanical software as a proposed solution to solve the adaptation problem. The tool can give a method for fixing the tibial component precisely without any varus\valgus malalignment.

BackgroundRotational alignment in total knee arthroplasty (TKA) is a crucial technical point that needs attention. We conducted a retrospective study to investigate whether a new robot‐assisted TKA (RA‐TKA) could improve the accuracy of rotational alignment and whether rotational alignment affects postoperative pain and functional evaluation of the knee.MethodsA total of 136 consecutive patients who underwent TKA were included in this study. Half of the patients underwent RA‐TKA and the other half underwent conventional TKA (CON‐TKA) by the same group of surgeons. Collect the relevant parameters.ResultsThe postoperative femoral rotation angle (FRA) was −0.72 ± 2.59° in the robot‐assisted group and 1.13 ± 2.73° in the conventional group, and were statistically significantly different (p < 0.001).ConclusionThis study provides preliminary evidence that the RA‐TKA provides more precise control of FRA than CON‐TKA, and verifies that tibial rotation angle and combined rotation angle affect postoperative knee pain and functional evaluation.
