WebMay 14, 2024 · Patella alta is a risk factor for patellofemoral pain and instability. Several measurement methods and imaging modalities are in use to measure patellar height. ... This study shows that the most reliable method to measure patella height is the Insall–Salvati ratio measured on conventional radiographs or the patellotrochlear index on MRI ... Web(9a) The Insall-Salvati Index is determined by dividing the length of the patellar tendon (PT) by the length of the patella (PL). Normal = 0.8 to 1.2. A ratio > 1.3 indicates patella alta. Excessive lateralization of the tibial tuberosity allows the patella to be pulled laterally in flexion and is considered to be a risk factor for instability.
WebSeveral methods are used to determine the presence of patella alta. Insall-Salvati were the first to describe a method of establishing patella height on the basis of the ratio of the length of the patella tendon to the diagonal length of the patella on lateral radiographs.
