“…The anatomical shape of the distal femur and its variations in antecurvation and anatomical axis compared to the mechanical axis could be another explanation for the higher rate of aseptic loosening of the femoral component. A large femoral canal diameter in the anteroposterior direction appeared to be an increased risk factor for aseptic loosening in cemented stems [24]. For uncemented stems like the ones of the RT-PLUS implant, it can be difficult to align and achieve press-fit anchorage with the straight cylindrical profile and no-offset femoral stem.…”

“…A recent article has demonstrated that the inner diaphyseal diameter of the distal femur 20 cm from the articular surface is one of the strongest independent risk factors related to aseptic loosening following primary TKA using cemented rotating hinge prosthesis [9]. Similar results have been presented for revision TKA procedures using cemented rotating hinge prosthesis by the same authors [10].…”

Introduction The inner diaphyseal diameter of the distal femur, at 20 cm from the lateral joint line, is the strongest risk factor for predicting aseptic loosening in total knee arthroplasty using rotating hinge prosthesis. In this context, the Citak classification has been introduced presenting three different types of the distal femur anatomy. The aim of the study is to develop a novel classification system for the proximal tibia. Materials and Methods Two-hundred patients with standard knee antero-posterior radiographs were included in this study. We measured the inner diameter of the tibia 16 cm distally from the tibial plateau and 3 cm distally from the tibial spine. The ratio between these two measurements was applied as the novel index ratio. Results According to the 25th and 75th percentiles, three groups can be clustered for each gender. A higher distribution of the type B pattern was found in female and male patients. However, type A with a narrow inner diaphyseal diameter was less common in female patients The median intra-observer reliability for rater 1 was 0.997. The inter-observer reliability was high (ICC 0.998). There was a moderate correlation between the AP diameter and height (r = 0,568); a low correlation between the AP diameter and weight (r = 0.376). The novel index shows no significant correlation between the index ratio and height (r = 0.082), weight (r = 0.014) or BMI (r= - 0.038). The novel index shows no statistically significant correlation between the index ratio and height (r = 0.082) or weight (r = 0.014) or BMI (r= - 0.038). Conclusion The novel classification presents three different types of tibia for each gender: type C has a wider inner diaphyseal diameter compared to type A with a narrow inner diaphyseal diameter. Type B has the widest distribution among the subjects.

We appreciate the letter written by Aliyev et al and the interest in our recently published study, in which we sought to analyze the risk factors of aseptic loosening in complex revision total knee arthroplasty using rotating hinge implants [1].We would like to address the concerns the authors discuss in their letter. Regarding the PJI diagnosis, all patients were diagnosed according to the standard pre-operative protocol of ENDO-Klinik [2] and the definition of PJI was made according to the first ICM criteria [3], as asked by Aliyev et alCorresponding to the second concern that the cement mantle thickness or the ratio of stem diameter to femoral canal diameter might be an independent risk factor is in general good aspects.
