Figure 1 Radiological parameters on X-ray imaging. A: Coronal angle of the tibial tunnel (α); B: Coronal angle of the femoral tunnel (β); C: Coronal position of the tibial tunnel AB/AC (%); D: Transplant orientation to joint angle (μ); E: Sagittal position of the tibial tunnel DE/DF (%); F: Position along Blumensaat’s line GH/GI (%); G: EndoButton position (anterior, middle, or posterior); H: Femoral tunnel angle to femoral diaphysis (º).
