Visualization of anatomical correspondence and point-dependent distance calculations in the predicted menisci. (a) The medial and lateral meniscus in 0° of knee flexion were plotted in light pink on the tibial plateau (yellow). Over the outer rim of the medial meniscus, 10 points were randomly allocated. (b) The medial and lateral meniscus in 0° of knee flexion were plotted in light grey, including the 10 previously allocated points. Based on the principle of anatomical correspondence, the 10 corresponding points were easily identified on the medial meniscus in 30° of knee flexion as the vertices with an identical index. The black arrow indicates how the point-dependent distance was calculated. (c) Axial view on the anterior horn of the medial meniscus in 0° (light grey) and 60° (light pink) of knee flexion, located on the tibial plateau (yellow). Utilizing the classic approach, an anteroposterior displacement of 5.74 mm was measured (green vector). Conversely, the novel methodology computed a point-specific distance of 6.24 mm (black vector).
