Insall-Salvati Ratio

The Insall-Salvati Ratio is the ratio of the length of the patella tendon to the length of the patella, when measured on an X-ray or MRI with the knees bent to 30 degrees.

The normal ratio is 0.75 - 1.50. Higher ratios suggest that the patella is abnormally high.

The patellar measurement is the greatest pole to pole length. The tendon measurement is from the back of the patella to the insertion of the tendon on the tibia.
