Clinical Implementation
Value Proposition
Patellar tendon-lateral femoral condyle friction syndrome (PT-LFCFS), also known as Hoffa fat pad impingement syndrome is a common cause of anterior knee pain. Related to patellar maltracking, there is impingement of the superolateral aspect of the infrapatellar fat pad (aka Hoffa fat pad) between the patellar tendon and the lateral femoral condyle. This finding can be subtle on MRI and can be missed by the radiologist.
Narrative(s)
A 32-year-old male presents with a history of chronic anterior knee pain. Radiologists can miss subtle cases of PF-LFCFS on MRI (PD-weighted images with fat-saturation/T2-weighted images with fat-saturation/STIR - i.e. fluid-sensitive sequence with fat suppression) and can benefit from an algorithm that can detect and alert the radiologist.
Workflow Description
Images obtained from the MRI are sent to the PACS/viewer and the AI model. The AI model analyzes the images. The model identifies an area of high signal intensity (on PD-WI with FS and T2-WI with FS) in the superolateral aspect of the infrapatellar fat pad. A message is sent to both the PACS/viewer and the reporting solution from the model with this information.
