Table 4.

The lateral tilt, medial tilt and sulcus angles of the femoral trochlea calculated based on 90° cross-sections of three-dimensional models of native and prosthetic knees (n = 42)

90° cross-section
	Lateral tilt angle (°)	Medial tilt angle (°)	Sulcus angle (°)
MP	15.2	11.7	153.1
Native knee	13.5 (2.8)	18.4 (3.2)	148.0 (4.8)

All parameters are reported as mean or mean (standard deviation)

Significant differences (p < 0.05) between the native and prosthetic knees were noted for all angles evaluated
