Table 2 Intraclass correlation coefficients for interobserver and intraobserver reliability in three AP views

From: The distal femur is a reliable guide for tibial plateau fracture reduction: a study of measurements on 3D CT scans in 84 healthy knees

Measure Interobserver reliability p Intraobserver reliability p
PCT-AP PIC-AP FC-AP PCT-AP PIC-AP FC-AP
dMC 0.71 0.61 0.50 0.012 0.67 0.57 0.63 0.253
dLC 0.84 0.44 0.44 0.70 0.81 0.76

  1. Values greater than 0.6 are considered good-to-excellent agreement
  2. AP anterior-posterior, dLA distance from lateral femoral articular edge to lateral tibial articular edge, dLC distance from lateral femoral condyle to lateral tibial condyle, dMA distance from medial femoral articular edge to medial tibial articular edge, dMC distance from medial femoral condyle to medial tibial condyle, FC fibular coverage
