Objective: The objective is to illustrate the MR imaging findings occurring in the posterior inferolateral patellar tendon and the lateral femoral condyle in patients experiencing chronic anterior and/or lateral knee pain. Material and methods: A retrospective review of the MR images in (patients who presented with chronic anterior or lateral knee pain. In all patients, postcontrast images were available. Results: Sagittal and axial imaging planes best demonstrated the patellar tendon and its relationship with the lateral femoral condyle. In all the patients, there was obliteration of the fat planes and abnormal signal intensity in the lateral soft tissues of the inferior patellofemoral joint. Enhancement after administration of gadolinium was noted in all cases in which contrast was administered. One patient showed cystic changes in the soft tissues adjacent to the lateral femoral condyle in addition to fat plane obliteration. Abnormal patellar alignment was noted in one patient. Patellar tendon pathology was seen in one patient. Conclusion: When assessing anterior knee symptoms, MR imaging facilitates the identification of changes associated with patellar tendon-lateral femoral condyle friction syndrome, which should be differentiated from other causes of anterior or lateral knee pain.
