[2 3 4] Lipohemarthrosis occurs in 35-41% of knees presenting with intra-articular fracture. Lipohemarthrosis can be diagnosed with plain radiography (X-rays) or computed tomography (CT . 1 Background. Four distinct signal bands were identified: superior band representing floating fat, a central band containing serum, an inferior band of . Tibial plateau fractures are intraarticular fractures, leading to lipohemarthrosis; Evaluate the lateral film for the "FBI" or fat-blood-interface, where the blood displaces the fat pad anteriorly; . 1). The lateral view ( B ) gives the best view of the patella and also allows the detection of knee joint effusions as . In 28 other patients with intraarticular fracture, only joint effusion without a fat-fluid level was depicted. Its presence can be suspected based upon patient history, physical exam, and multiple imaging modalities; however, the best way to diagnose hemarthrosis is with arthrocentesis with synovial fluid analysis. Lipohemarthrosis is not entirely uncommon in intra-articular fractures, occurring in 35%-41% of cases [1,5,6]. In traumatized knees particularly with intra-articular fractures, fat, presumably liberated from the bone marrow, may layer itself above extravasated blood and produce a fluid level on the roentgenogram. [5 6] Thus, lipohemarthrosis is an important sign, since knee . This is the American ICD-10-CM version of M25.062 - other international versions of ICD-10 M25.062 may differ.

(See 'Knee injury' below and 'Lipohemarthrosis' below and 'Minimal injuries' below and 'Postoperative' below.) Lipohemarthrosis of the knee: MRI as an alternative to the puncture of the knee joint. Note the normal suprapatellar pouch between fat pads above the patella ( asterisks) - widening of these fat pads or increased density in this area can indicate a knee . In 28 other patients with intraarticular fracture, only joint effusion without a fat-fluid level was depicted. Lipohemarthrosis results from an intra-articular fracture with escape of fat and blood from the bone marrow into the joint, and is most frequently seen in the knee, associated with a tibial plateau fracture or distal femoral fracture; rarely a patellar fracture. Chapter 6. for lipohemarthrosis without obvious fracture on knee X-ray). A new sign for the diagnosis of lipohemarthrosis on vertical beam lateral knee radiographs depends upon visualization of the joint capsule due to the presence of fat lying both within and outside of the joint. The authors investigated sequential changes in the appearance of lipohemarthrosis of the knee as demonstrated by MR imaging. A tibial plateau fracture is a common knee fracture. 1989;173(1):189-91.

In 1942, radiography was used to identify the fat-blood interface on lateral radiographs of the knee. A cross-table lateral view of a normal knee shows the radiolucency of the suprapatellar fat pad. Accuracy in the roentgenographic demonstration and clinical appraisal of the extent of the injury with the least movement of the patient are advisable. M25.062 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. Left knee radiographs demonstrate fracture from the lateral aspect of the tibial plateau (Segond fracture), avulsion from the medial femoral condyle (Steida fracture), and tibial intercondylar eminence. The radiographs of 268 patients with knee trauma were retrospectively reviewed. The knee is a complex hinge joint and one of the most common sites of MSK injuries. 2. The accumulation of bloody fluid is due to soft tissue injury or to bone or osteochondral fracture.
