Acute patellar dislocation (APD) is associated with a spectrum of soft tissue and osteochondral injuries. The cartilage can be torn, crushed or damaged and, in rare cases, a cyst can form in the cartilage. 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. Osteochondral injury implies an injury to the joint surface or articular cartilage with some of the underlying bone. 18 Acute Osteochondral Defects in the Knee JOHN G. COSTOUROS, MARC R. SAFRAN, AND GREGORY B. MALETIS Despite surgical and technologic advancements, the treatment of osteochondral defects continues to challenge orthopaedic surgeons. When the entire cartilage surface of the knee begins to break down, osteoarthritis is usually the cause. Such lesions are a tear or fracture in the cartilage covering one of the bones in a joint. The procedure also can be used for complex biologic knee reconstruction in the setting of osteonecrosis, fracture malunion, or posttraumatic arthritis. Armstrong CG, Mow VC. Other areas affected include under the patella (knee cap) or along the talus bone in the ankle. If there is a fracture (break) in part of the condyle, this is known as a fracture … A femoral condyle is the ball-shape located at the end of the femur (thigh bone). Less often, this type of fracture can affect the metatarsal bone of the foot. These incidental lesions of vulnerable joint cartilage are often neglected in the initial phase, which is regrettable given their … Femoral osteochondral fractures are the result of a shearing force when the foot is planted on the ground and the knee twists over the foot. Once reposition of the osteochondral fragment was achieved, suture tape was tied over the Endobutton. Our e-learning platform contains high resolution images and a certified CME of the Knee arthroscopy and microfracture of osteochondral defect surgical … The knee examination revealed a joint effusion under tension and the arthrocentesis revealed 70mm3 of hematic liquid, with evidence of fat deposits. Sometimes after a jarring or twisting injury of the knee, rather than tearing a cartilage or a ligament, the articular cartilage may be damaged. Osteochondritis dissecans (OCD or OD) is a joint disorder primarily of the subchondral bone in which cracks form in the articular cartilage and the underlying subchondral bone. Osteochondral Lesion Picture 2 – Osteochondral fracture of the femur. Although they most frequently occur in the knee, other joints may be involved including the ankle and elbow. For fixation, left knee was kept in fully extended position preventing posterior sagging of the tibia. Wilson's Test: The knee is held in 90° to 30° from full extension while rotating the tibia. S80-S89 Injuries to the knee and lower leg › S82-Fracture of lower leg, including ankle › 2021 ICD-10-CM Diagnosis Code S82.01; 2021 ICD-10-CM Diagnosis Code S82 ... S82.01 Osteochondral fracture of patella S82.011 Displaced osteochondral fracture of right patella . Author links open overlay panel Arthur Krida M.D., F.A.C.S.. Show more The tense knee hemarthrosis made us suspect of an OCF. 13, 23 Introduction: Femoral or patellar osteochondral fractures complicating patellar dislocation are more frequently observed in adolescents than in adults. We present a case of large osteochondral fracture of lateral femoral condyle involving the articular surface in a fifteen-year-old male with a positive history of significant weight gain of 5 kilograms in last six months. 13 . An osteochondral defect refers to a focal area of damage that involves both the cartilage and a piece of underlying bone. 4 . 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. After general anesthesia the Osteochondral lesions are common in children and may arise from a variety of etiologies. J Bone Joint Surg Am. PubMed Google Scholar. Whereas osteochondritis is the leading cause of cartilage loss of the knee's medial condyle in children, osteochondral fractures (OCFs) preferentially involve the lateral condyle (as well as the femoropatellar compartment) , .The rare cases of osteochondritis of the lateral condyle should suggest a search for malformative discoid meniscus . Learn the Knee arthroscopy and microfracture of osteochondral defect surgical technique with step by step instructions on OrthOracle. The knee can be aspirated for fat globules, which can indicate an osteochondral fracture, and high inflammatory markers in the aspirate can also suggest osteochondral injury. Articular cartilage lesions are common and have been reported in 63% of over 31,000 arthroscopic procedures in one series.1 … In later stages of the disorder there will be swelling of the affected joint which catches and locks during movement. Osteochondral fractures are relatively uncommon injuries that typically present after an acute or subacute traumatic injury. OCD usually causes pain during and after sports. Introduction. Osteochondral fracture of the knee-joint ☆. The sensitive location of the abandoned section of the osteochondral fracture can be felt, when the knee is in 90° of flexion . 1965;47:1491–1502. Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Osteochondral Injury, Knee Osteochondral lesion of the knee (C2536) Knee & Sports - Osteochondritis Dissecans E 3/18/2016 459 . 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). The test is positive when internal rotation is painful and external rotation relieves symptoms. 2 Lateral patellar dislocation can also lead to osteochondral injury to anteriolateral non-weight bearing (NWB) part of the LFC. Based on multiple studies demonstrating similar functional outcomes after both conservative and operative procedures for treatment of APD, Conservative treatment has been traditionally the preferred option for APD without an osteochondral fracture (OCF) [1,2,3,4,5,6,7,8]. Osteochondral fracture fixation is traditionally performed in the acute setting with internal fixation procedures using pins or compression screws through the fragment. Variations in the intrinsic mechanical properties of human … 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. Osteochondral fractures of lateral femoral condyle are common in adolescents and young adults. These can occur from an acute traumatic injury to the knee … Osteochondral lesions or osteochondritis dessicans can occur in any joint, but are most common in the knee and ankle. 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. They are usually caused by direct trauma or twisting injuries of the knee. Patella (6%)7. Osteochondral fracture of the lateral femoral condyle is a rare injury of the knee joint, which mostly occurs in adolescence 1.In adolescence, the cartilage‐bone interface is the weakest transitional area in the knee joint, and there is no obvious boundary between calcified and uncalcified cartilage 2.The biomechanical strength of immature osteochondral junction was lower … Introduction. On the other hand, osteochondral fracture within the knee joint may be caused by impaction, avulsion or sheering forces. Screws and Kirschner wires both absorbable and nonabsorbable have been the common mode of fixation of these fractures. Indications for OCA transplantation in the knee include primary management of large chondral or osteochondral defects and salvage of previously failed cartilage repair. Osteochondral fracture in the knee joint associated with hypermobility and dislocation of the patella. 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. Osteochondral fracture of the lateral femoral condyle is a rare intra‐articular injury with or without patellar dislocation. Chondral injuries involve only the articular cartilage.
