Surgical, [71]. Paa L, Vesel R, Koi J, et al. Knee Surg Sports Traumatol Arthrosc. [10] Werner and Miller[11] reported that iatrogenic injury is a cause of Hoffa fracture that cannot be ignored. A case report. (B) The sutures passing through the bone canal and the corresponding sutures on the anchor were tightened and fixed. After 6 months, the patient could resume normal sporting activities, and the knee joint extension and flexion were normal without knee instability and pain. Knee Surg Sports Traumatol Arthrosc 2011;19:3209. Femoral Condyle Fractures - Symptoms, Causes, Treatment | Physio Difficulties involved in the Hoffa fractures [in German]. For simple lateral condylar Hoffa fractures, a patellar anterolateral approach is most commonly used. Type II is a fracture horizontal to the base of the posterior condyle with fracture lines located posterior to the attachment point of the lateral collateral ligament. At the same time, forces on the distal tibia are transferred to the tibial plateau, resulting in great shear stress between the femoral condyle and the tibial plateau. The authors have no funding and conflicts of interest to disclose. [9]. A radiographic examination should include anteroposterior, lateral, oblique, and stress views of the knee. When the patient was sent to the emergency room, the right knee swelled obviously, tenderness over the medial border of the patella, the apprehension test was positive, lateral stress test was negative, and the knee range of motion:F/E 90/0. [89]. The appropriate surgical plan is chosen based on the location of the Hoffa fracture, characteristics of the fracture line, fracture severity, and associated injuries. Emerg Radiol 2015;22:3378. Pitfalls associated with fixation of osteochondritis dissecans fragments using bioabsorbable screws. [7] Nondisplaced Hoffa fractures are difficult to visualize on anterior and lateral radiographs of the knee. Fracture and dislocation compendium: Orthopaedic Trauma Association Committee for Coding and, [35]. -, Biau DJ, Schranz PJ. Malays Orthop J 2017;11:204. Lee SY, Niikura T, Iwakura T, et al. Previous article . The patient was a 20-year-old man who sustained a noncontact left knee hyperextension injury while playing soccer. Active and passive knee flexion exercise of the right knee was gradually strengthened 6 weeks after operation. Preliminary X-ray examination showed osteochondral defects of LFC and loose body in knee joint (Fig. Coronal plane fracture of the femoral condyles: anatomy, injury patterns, and approach to management of the Hoffa fragment. computed tomography scan and magnetic resonance (MRI) examination of knee joint further confirmed loose body within the knee joint, osteochondral defect in weight-bearing area of LFC and avulsion of medial patellofemoral ligament (Fig. In addition to changes in bone mineral composition and a reduced proportion of bone matrix in patients with osteoporosis, changes in bone microstructure, thinning of bone cortex, and reduction in the number and size of bone trabeculae result in a decreased bone load capacity[26] and an increased risk of a Hoffa fracture with low-energy trauma. government site. [10,38] Local manifestations of a Hoffa fracture include knee swelling, pain, skin color changes (with or without skin defects), limited knee mobility, and a positive floating patella test.
