From: Comparison of tibial anatomical-mechanical axis angles and patellar positions between tibial plateau levelling osteotomy (TPLO) and modified cranial closing wedge osteotomy (AMA-based CCWO) for the treatment of cranial cruciate ligament disease in large dogs with tibial plateau slopes greater than 30° and clinically normal Labradors retrievers

Measurements made to calculate the Insall-Salvati index (ISI) and the Guenego-Verwaerde index (GVI). Mediolateral radiograph of a normal contralateral stifle illustrating the measurements made to calculate the Insall-Salvati index (ISI) and the Guenego-Verwaerde index (GVI). The ISI is the ratio of the patellar ligament length (PLL) to the patellar length (PL), and the GVI is the ratio of D to the patellar joint surface length (PJSL). D, Distance between the point at the intersection of the MA and the tibial plateau and the line perpendicular to the distal aspect of the PJSL
