“…First, we could not determine the influence of sex because sufficient numbers of male patients could not be gathered. Although patients with varus knee OA undergoing TKA are predominantly women, previous reports [3,13,22] have demonstrated several sex differences. Additional studies with large numbers are required to confirm the influence of sex.…”

Background Tibia vara seen in Japanese patients reportedly influences the tibial component alignment when performing TKA. However, it is unclear whether tibia vara affects the component position and size selection. Questions/purposes We therefore determined (1) the amount of medial tibial bow, (2) whether the tibia vara influences the aspect ratio of the tibial resected surface in aligning the tibial component with the tibial shaft axis, and (3) whether currently available tibial components fit the shapes of resected proximal tibias in terms of aspect ratio. Methods We measured the tibia vara angle (TVA), proximal varus angle (PVA), and the mediolateral and middle AP dimensions of the resected surface using threedimensional preoperative planning software in 90 knees of 74 female patients with varus osteoarthritis. We determined the correlations of the aspect ratio with TVA or PVA and compared the aspect ratios to those of five prosthesis designs. Results The mean TVA and PVA were 0.6°and 2.0°, respectively. The aspect ratio negatively correlated with both TVA and PVA (r = À0.53 and À0.55, respectively). The mean aspect ratio of the resected surface was 1.48 but gradually decreased with increasing AP dimension, whereas four of the five prostheses had a constant aspect ratio. Conclusions The aspect ratio of resected tibial surface was inversely correlated to the degree of tibia vara, and currently available prosthesis designs do not fit well to the resected surface in terms of aspect ratio. Clinical Relevance The design of a tibial component with a smaller aspect ratio could be developed to obtain better bone coverage in Japanese patients.

“…Previous studies have analyzed the anthropometric measurements of the proximal tibia 1,5,7,8 . In our study, the tibia did not show a difference in AR between men and women when using the medial plateau and a slight difference when using the lateral plateau with women increasing width faster than men.…”

“…Several authors have demonstrated distal femoral morphological differences, with the female knee tending to be slightly narrower than the male knee for any given anteroposterior dimension [7,10]. However, there is substantial variability in these patterns [7,10], and there are more differences between races than between genders [11,14,[17][18][19][20].…”
