AbstractInfrapatellar fat pad impingement represents a source of anterior knee pain that is often overlooked. Due to the scarcity of reports related to this disorder, we conducted a systematic review of the literature related to infrapatellar fat pad impingement in evaluating the following: (1) clinical presentation, (2) imaging, (3) management, and (4) clinical outcomes. A systematic review was conducted investigating all available primary literature related to the clinical presentation, imaging, management, and outcomes of infrapatellar fat pad impingement syndrome. A total of 15 studies (9 case reports, 1 case series, and 5 retrospective studies) comprising 167 patients met eligibility criteria for this review. Patients with infrapatellar fat pad impingement were found to most often present with anterior knee pain that worsened with activity, and was frequently associated with trauma. Anterior knee pain, tenderness to palpation over the patellar tendon, loss in terminal extension, and pain with direct pressure on the medial or lateral side of the patella with the knee extended was often found on examination. Although patients may have classic imaging findings on magnetic resonance imaging (localized edema of the infrapatellar fat pad, deep fluid-filled infrapatellar bursa, nonvisualization of clefts, fibrosis, and calcifications), not all patients had positive imaging findings, thus making infrapatellar fat pad impingement a clinical diagnosis. Treatment begins with nonoperative management, but in recalcitrant cases, patients can be surgically treated with arthroscopic fat pad resection. Most patients who undergo operative treatment report improvement or complete resolution of symptoms in terms of pain and range of motion, and are able to return to work. To the best of our knowledge, this is the first comprehensive review on infrapatellar fat pad impingement to better aid the orthopaedic surgeons in diagnosing, treating, and managing patient expectations for this often overlooked knee pathology.

Introduction. Synovial chondromatosis is a benign disease of synovial membrane usually affecting knee, elbow and shoulder joints. It rarely appears as a solitary formation and exceptionally within Hoffa?s fat pad. Case Report. We report a case of solitary synovial chondromatosis within Hoffa?s fat pad as a cause of its impingement in a female patient aged 63. At first, the patient had anterior knee pain with limited extension of the knee. Standard radiogram showed only mild patellofemoral osteoarthritic changes. Magnetic resonance of the knee showed ovoid solitary formation within Hoffa?s fat pad repressing its superior part between the kneecap and distal femur. Histopathological examination confirmed a case of extra-articular synovial chondromatosis. The tumorous mass was extracted surgically en bloc. Conclusion. Solitary synovial chondromatosis is an uncommon cause of Hoffa?s fat pad impingement and anterior knee pain in elderly female patients and can easily be misinterpreted as a different diagnosis.

Objective: To evaluate the role of oedema like changes of the suprapatellar fat pad in the development of anterior knee pain. Methods: Total 156 knee MRIs of 150 patients from December 2015 to July 2019 were retrospectively evaluated by a radiologist with 13 years of MRI experience for the configuration of the suprapatellar fat pads. Population was divided into two groups according to referring physicians’ notes for presence of anterior knee pain. The study group consisted of the patients with complaints of anterior knee pain. The control group consisted of patients without anterior knee pain. Maximum craniocaudal, anteroposterior and oblique diameters and relative signal intensity indexes of the suprapatellar fat pads were measured and compared between the groups. Configurations of the fat pads were recorded (triangular shaped vs convex posterior bordered suprapatellar fat pads), and measurements of the triangular shaped and convex posterior bordered suprapatellar fat pads were compared. Student t test was used for statistical analysis. Statistically significant differences and correlations were defined as p<0.05. Results: The diameters and relative signal intensity indexes of the fat pads showed no significant difference between the groups (p=0.588, 0.744, 0.874 and 0.201, respectively). Anteroposterior and oblique diameters and relative signal intensity indexes of the suprapatellar fat pads were correlated with convex posterior border (p=0.001, 0.003 and 0.000, respectively). Conclusion: Oedema-like changes of the suprapatellar fat pad seen at knee MRIs are correlated with the configuration of the fat pad, but are rarely associated with anterior knee pain.
