The type of Ith prosthesis for the Jth subject and the corresponding result indicator for the Ith prosthesis are referred to as the «X» prosthesis type. In this model, {1} the model is ,,,{0},» the object was taken into account as a random effect in the model. The variance covariance structure for random effects assumes that all random effects are independent. All mixed linear models converge successfully. In addition, we assessed the magnitude of the differences between BP and MYO prostheses from Hedges`g as a measure of effects size: there was no significant difference in the miscalcization between BP and MYO prostheses (Table 3, Figure 3b). However, there were differences in the miscalc estimation between participants with acquired limb loss and congenital absence for certain conditions (fig. 3c). Regardless of the type of prosthesis, participants with acquired limb loss overestimate their residual length when wearing their prosthesis more than participants with congenital absence (P-RL, innate average: 4.4 ± 5.1 cm; average acquired: 9.8 ± 2.8 cm; g – 1.31). The three participants in the congenital absence estimated their residual length if they did not wear their prosthesis, but all participants with acquired limb loss overestimated (NP-RL, congenital average: 0.9 ± 0.9 cm; gained average: 5.7 ± 2.2 cm; g – 2.25).

When wearing the prosthesis, participants underestimated their prosthetic length with a congenital absence, while participants with acquired limb loss tended to overestimate it (P-PT, innate average: 4.4 ± 2.9 cm; average gained: 2.4 ± 2.6 cm; g – 2.24). Participants with congenital absence also underestimated their prosthetic length without wearing it to a greater extent than participants with acquired limb loss (NP-PT, congenital average value: 6.0 ± 4.6 cm; average gained value: 0.6 ± 5.2 cm; g – 0.97).

We assumed that the incidence of aseptic easing in patients treated with an OFI-Y or OTI would be higher because of the fixation differences where OFI-Y/OTI is attached in metaphysical and epiphysical bones, while OFI-C has a diaphysical fixation. The OFI-Y and OTI are also much shorter, which would lead to a smaller surface area for osseo-integration. To balance the Ossé`s integration domain, ofI-Y and OTI were designed with a 3D grid structure that creates a surface 3.7 times larger than that of a 3D grid-free implant. In this study, there was no aseptic release of implants that could indicate that ISOs with short implant lengths, with the correct surfaces of additional mesh and locking screws, may lead to adequate integration into short femoral or tibal remnants.
