摘要: Purpose To determine whether the sulcus angle and lateral to medial facet ratio correlate with patella displacement tilt in patients without instability. Methods Computed tomography images of lower limb 64 known arthropathy were collected. Three-dimensional models a unified coordinate system rebuilt by using Mimics software. The angle, ratio, trochlear inclination patellar groove, tibial tuberosity-trochlear groove (TT-TG) distance, bisect offset index, measured. Pearson's correlation test was used relationship between aforementioned parameters. Results Data from 51 analyzed. negatively correlated (p < 0.001, r = 0.8406) positively index 0.003, 0.634) 0.03, 0.551); TT-TG distance 0.643) 0.026, 0.559). Conclusion can influence tracking stable knee joints.
