Another multicenter case series using ACI for OCD demonstrated significant improvements, but more than a third of patients required secondary surgical débridement. Whether OLT is a precursor to more generalised arthrosis of the ankle remains unclear, but the … Animals: Dogs (n=14) with caudocentral humeral head OCD (16 shoulders). Osteochondritis dissecans (OCD) is a condition that develops in joints, most often in children and adolescents. There were 41% failures in the microfracture group compared with none in the mosaic osteochondral autograft transplantation group at the final follow-up. Osteochondral allograft transplantation has a long history, dating back to 1957, when Smillie proposed its use for OCD. Fresh osteochondral allografts address both the cartilage and bone deficits. The use of a fresh osteochondral allograft for treatment of a lesion of the femoral condyle is relatively new, and we report its use in a unique situation involving identical twins who both presented with osteochondritis dissecans of the same anatomic location within 2 years of each other. Stable fragments are those that are held in place by intact … The other name that gets associated with this problem is Osteochondritis Dissecans. Clot formation secondary to marrow stimulation produces disorganized fibrocartilage characterized by a high concentration of type I collagen rather than type II collagen, which comprises hyaline cartilage. Osteochondral lesions, also known as osteochondritis dissecans, are areas of damaged bone and cartilage on the surface of the ankle bone (the talus), usually caused by an ankle injury. Large defects cannot be filled due to donor site morbidity, and there may be problems with articular cartilage incongruence. Objective— To establish whether osteochondral autograft transfer (OAT) procedures for osteochondritis dissecans (OCD) of the canine elbow would restore articular contour, resurface osteochondral defects with hyaline cartilage, and resolve lameness in the short term. L.M. Because clinical findings are often subtle, diagnosis requires a high index of suspicion. Conditions: Osteochondral Defect; Osteochondritis Dissecans . The Department of Orthopaedic Surgery at Washington University School of Medicine in St. Louis has no control over third-party websites and does not review such websites. Collagen-covered ACI (ACI-C) has been described in a case series, showing positive clinical results at 4 years, but most cases that underwent biopsy revealed fibrocartilage. Osteochondral Defect listed as OCD Looking for abbreviations of OCD? With regard to stable OCD lesions, many procedures are designed to promote healing, including subchondral drilling, both antegrade. The living chondrocytes from the transplant become a viable part of the recipient’s cartilage matrix, and the transplanted bone is incorporated by the host bone. Patients close to or beyond skeletal maturity have a worse prognosis for healing with activity modifications. The clinical presentation is characterised by an acute or chronic onset of symptoms. Some research has also shown factors such as age older than 30 years and a history of two or more previous surgeries on the joint are associated with poorer outcomes. Osteochondral defect. The good news is that surgery can be very helpful depending on the type of specific injury we have. Osteochondritis Dissecans and Large Osteochondral Defects of the Knee. Restoring this subchondral bone loss can present many challenges to the surgeon, both with microfracture, and other cartilage restoration procedures. If surgery is further along, then sometimes we have to remove the offending part of the bone and stimulate healing of the cartilage surface. Please note that OCD is a commonly used abbreviation for both osteochondral defect and osteochondritis dissecans, two closely related conditions.
