"Most often will not be identifiable. May show new patella baja."
"T1: low signal intensity"
"T2: low signal intensity"
"An anterior interval lesion is an area of localised arthrofibrosis of the anterior interval, which can occur after ACL reconstruction."
"The anterior interval of the knee is found posterior to Hoffa’s fat pad, between the inferior and posterior patella and the anterosuperior tibial plateau 1. Arthrofibrosis can occur after ACL reconstruction, which can be localised in the form of cyclops lesions and/or anterior interval lesions. Different terminology is used in the literature when referring to anterior interval lesions, and these include intrapatellar fat pad fibrosis 2."
"Post ACL reconstruction, patients can present with a lack of knee extension, new patella baja 3, and/or a mechanical endpoint in knee movements."
"The ACL reconstruction should be assessed for possible areas of arthrofibrosis and MRI is the investigation of choice to assess for arthrofibrosis and intra-articular pathology of the knee."
