Radiographically, they are lucent defect traversing the length of epiphysis, and may have sharp or irregular borders. A standard arthroscopic examination was performed via anteromedial and anterolateral portals. Literature data do not report clinical records with significant number of cases and follow-up. CrossRef Google Scholar Additional MRI findings were scored as present or absent: focal chondral thinning or absence at the notch of Harty, focal subcortical osteosclerosis at the anteromedial margin of the tibial plafond, osteochondral lesions elsewhere in the ankle, subchondral edema signal or cystic change at the tibial plafond, and the presence of an ankle joint effusion. BACKGROUND: Osteochondral lesions of the distal tibial plafond are uncommon compared with talar lesions. There is no soft tissue swelling The distal tibial physis is also often irregular. Gorbachova T, Melenevsky Y, Cohen M, Cerniglia BW. Imaging strategies for the knee. Elias I, Raikin SM, Schweitzer ME, Besser MP, Morrison WB, Zoga AC. Sanders TG, Paruchuri NB, Zlatkin MB. It is often used synonymously with osteochondral injury/defect and in the pediatric population. In the quest to replace osteochondral defects with hyaline cartilage, Brittberg et al. In distal tibia the cleft tends to prefer the medial plafond at its connection with the medial malleolus. first treated lesions in the knee with chondrocytes harvested from non-weight-bearing parts of the knee, cultured and then placed in the defect, covered with a periosteal flap from the ipsilateral tibia . Glossary of terms for musculoskeletal radiology. Thieme, 2006. The necrotic fragment usually becomes revascularised and reattaches to the surrounding bone. There are few cases describing this lesion in the literature, with little information on mechanism of injury, history/physical findings or recommendations for management. osteochondral lesions of the tibial plafond may be initially mistaken for thoses of the talar dome. AJR Am J Roentgenol. 9.1 Anteroposterior radiograph (a) and MRI (b) demonstrating an osteochondral defect in the tibial plafond (OLTP) with a large overlying periarticular cyst Diagnosis is usually made on a CT scan or magnetic resonance imaging (MRI) [ 2, 6 ]. Clinical and MRI Outcomes After Arthroscopic Microfracture of Osteochondral Lesions of the Distal Tibial Plafond. MRI scans were assessed postoperatively with use of the Magnetic Resonance Observation of Cartilage Repair Tissue … Osteochondral injury staging system for MRI attempts to grade the stability and severity of osteochondral injury and is used to plan management. (1999) Foot & ankle international. Always check ankle X-rays for a talar dome OCD. At earlier stages (stage 1 to 4), a number of options exist including: The knee is a complex synovial joint that can be affected by a range of pathologies: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Isolated lesions of cartilage or subchondral bone are not considered an OCD 6.. Osteochondritis dissecans of the tibial plafond is a rare condition that may not be detectable on radiography. This is essential in determining management. Isolated lesions of cartilage or subchondral bone are not considered an OCD 6.Â. A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. The objective of this study was to assess functional and magnetic resonance imaging (MRI) outcomes following microfracture for tibial osteochondral lesions. However, they are insensitive to grading lower stage lesions and are inadequate in predicting stability. Terminology. 2006;187 (5): 1332-7. Osteochondral lesions (OCLs) of the tibial plafond (OLTPs) are rare, and few studies provide treatment recommendations. following anterior cruciate ligament repair), femoral condyle (most common in the lateral aspect of the medial femoral condyle), the signal is variable with intermediate to low signal adjacent to fragment and variable fragment signal, low signal loose bodies, outlined by high signal fluid, donor defect filled with high signal fluid. eochondral lesions in thirty-one ankles underwent arthroscopic microfracture. The objective of this study was to assess functional and magnetic resonance imaging (MRI) outcomes following microfracture for tibial osteochondral lesions. Such lesions are a tear or fracture in the cartilage covering one of the bones in a joint. ... Radiology. In my experience these lesions have a good healing potential without developing a loose body. This term covers a wide spectrum of pathologies including (sub)chondral contusion, osteochondritis dissecans, osteochondral fracture and osteoarthritis resulting from longstanding disease. {"url":"/signup-modal-props.json?lang=us\u0026email="}. OBJECTIVES: Osteochondral lesions of the distal tibial plafond (OLTP) are rare and far less common than osteochondral lesions of the talus. Kaplan P. Musculoskeletal MRI. The aim of our study was to … Ankle: 4 to 14 times more common in the talus (56% posteromedial, anteromedial 44%) than the tibial plafond. OCD usually causes pain during and after sports. In later stages of the disorder there will be swelling of the affected joint which catches and locks during movement. OCD is suggested by a loss of the sharp cortical line of the articular surface. Osteochondral lesions of the distal tibial plafond (OLTP) are rare and far less common than osteochondral lesions of the talus. A retrospective review was conducted for patients who underwent arthroscopic microfracture surgery for osteochondral lesions of the tibial plafond from January 2014 to June 2017. The Foot and Ankle Outcome Score (FAOS) and Short Form-12 (SF-12) general health questionnaire were used to obtain patient-reported functional outcome scores preoperatively and postoperatively.
