(1) BACKGROUND: Patellar tendinopathy (PT) is an overuse condition of the knee extensor mechanism characterized by ventral knee pain at the lower pole of the patella and limited functionality. (2) METHODS: In this retrospective study, a group of patients with PT ( = ) was compared with a control group ( = ) in terms of patient-related data and magnetic resonance imaging (MRI) characteristics. (3) RESULTS: Patellar height was higher in the PT patient group and there was a significant difference in Caton-Deschamps index (CD) compared to the control group ( = 0.021). Patients with PT showed a lower patella-patellar tendon angle (PPTA) ( = 0.011). The patellar tendon thickness (PTT) in the proximal (PTTprox), middle (PTTmid) and distal (PTTdistal) part of the tendon was significantly thickened ( < 0.001). Increased signal intensity in MRI was detected in symptomatic tendons over 6 months compared to a duration of less than 6 months ( = 0.025). A significant relationship between the PTTprox and an increased signal intensity was observed ( < 0.001). (4) CONCLUSIONS: Patients with PT showed a significant difference in the patellar height and PPTA. With persistence of symptoms over 6 months, MRI seems suitable to detect the morphologic tendon changes and further identify patients suitable for surgical procedures.
