1965;47:1491–1502. The cartilage can be torn, crushed or damaged and, in rare cases, a cyst can form in the cartilage. Osteochondral lesion of the knee (C2536) Knee & Sports - Osteochondritis Dissecans E 3/18/2016 459 . Introduction. Osteochondral fracture of the patella is a common concomitant injury of the knee, especially in lateral patellar instability, and the importance of early stable fixation with minimal complication and early mobilization should be emphasized. The Arthrex approach to osteochondral fixation includes the Chondral Dart a bioabsorbable PLLA Chondral Dart featuring a unique, double reversed barbed design, and Bio-Compression Screws offering interfragmentary compression and a headless profile to promote healing. Then, the stability of osteochondral fragment was confirmed during full … Osteochondral junction 7. Osteochondral fractures are relatively uncommon injuries that typically present after an acute or subacute traumatic injury. The purpose of this article is to describe in detail a one-stage osteochondral fracture repair technique with knotless anchors and interconnected crossing suture sliding loops for the knee. Introduction: Femoral or patellar osteochondral fractures complicating patellar dislocation are more frequently observed in adolescents than in adults. The knee radiograms revealed a free articular body that we interpreted as a possible osteochondral patella fracture (Figures 1 & 2). 2 Lateral patellar dislocation can also lead to osteochondral injury to anteriolateral non-weight bearing (NWB) part of the LFC. An osteochondral fracture involves cartilage and the subchondral bone plate, and may demonstrate cortical disruption, cortical depression, fragmentation or a combination of these findings. On the other hand, osteochondral fracture within the knee joint may be caused by impaction, avulsion or sheering forces. Our e-learning platform contains high resolution images and a certified CME of the Knee arthroscopy and microfracture of osteochondral defect surgical … Indications for OCA transplantation in the knee include primary management of large chondral or osteochondral defects and salvage of previously failed cartilage repair. Ribs (4%) (1%)--Stiell 1996, Weber 1995, Bauer 1995 --Data from Freed and Shields 1984 12. 4 . 13, 23 After general anesthesia the An osteochondral injury or defect occurs when a piece of the cartilage, along with a part of the bone underneath, is chipped off, leaving a gap. There are two condyles on each leg known as the medial and lateral femoral condyles. 22 Ultrasound can reliably identify loose bodies and osteochondral injury after patellar dislocation. The procedure also can be used for complex biologic knee reconstruction in the setting of osteonecrosis, fracture malunion, or posttraumatic arthritis. In later stages of the disorder there will be swelling of the affected joint which catches and locks during movement. Osteochondral fractures of lateral femoral condyle are common in adolescents and young adults. Sometimes after a jarring or twisting injury of the knee, rather than tearing a cartilage or a ligament, the articular cartilage may be damaged. Osteochondral fracture fixation is traditionally performed in the acute setting with internal fixation procedures using pins or compression screws through the fragment. Management of a first-time traumatic dislocation is normally non-operative unless there is an osteochondral fracture, substantial disruption of the medial patellar stabilisers or a laterally subluxated patella with normal alignment of the contralateral knee. Once reposition of the osteochondral fragment was achieved, suture tape was tied over the Endobutton. Wilson's Test: The knee is held in 90° to 30° from full extension while rotating the tibia. Variations in the intrinsic mechanical properties of human … Osteochondral fracture in the knee joint associated with hypermobility and dislocation of the patella. When the entire cartilage surface of the knee begins to break down, osteoarthritis is usually the cause. A femoral condyle is the ball-shape located at the end of the femur (thigh bone). Chondral injuries involve only the articular cartilage. An osteochondral defect refers to a focal area of damage that involves both the cartilage and a piece of underlying bone. The less severe cases can benefit from rest, with the patient refraining from certain activities (especially those that involve weight bearing in the respective joint). 3/18/2016 459 knee radiograms revealed a joint effusion under tension and the arthrocentesis revealed 70mm3 of hematic liquid with!
