Concerning the new techniques of biomimetic osteochondral scaffolds and bone marrow-derived cell transplantation, they have provided results comparable to those of ACI and shown they are capable of overcoming some of the disadvantages of the older tissue regeneration techniques. However, the former actually does not … Required fields are marked *. Surgical treatment options for the management of focal chondral and osteochondral lesions in the knee include biological solutions and focal metal implants. During the second arthroscopic procedure, the surgeon implants the expanded cultured chondrocytes, which were seeded onto a hyaluronic acid (HA) membrane. Osteochondral lesions cause significant pain, discomfort, swelling, and reduced function in the knee joint. Techniques such as microfracture, popularized by Steadman, [17, 18] and autologous chondrocyte transplantation have shown some promise. An osteochondritis dissecans (OCD) lesion is seen prior to treatment. The surgeon treated the OCD lesion by This entire procedure is performed arthroscopically and involves a single surgical session. A bone marrow-derived cell transplantation procedure starts with the aspiration of bone marrow from the patient’s iliac crest. Otherwise, for the majority of cases of PF chondral/osteochondral lesion(s) and/or underlying malalignment, failure of up to 6 months of conservative treatment is warranted. While OCD may affect any joint, the knee tends to be the most commonly affected, and constitutes 75% of all cases. The Journal of Knee Surgery Vol. Particular care should also be taken during the implantation of the graft to ensure that once the graft is in place, its articular surface is not positioned higher or lower than the level of the surrounding articular cartilage. Overall, cartilage restoration techniques have yielded favorable clinical outcomes and can be successfully employed to treat these challenging large focal lesions.Thieme. Patient- and lesion-specific factors must be identified when evaluating a patient with an articular cartilage defect.

Performing a second-generation ACI procedure with bone grafting requires two arthroscopic surgical sessions. Drilling, open or arthroscopic fixation, fragment excision, microfractures, osteochondral grafting (with autograft or allograft) and autologous chondrocyte implantation (ACI) have been described as suitable treatment options. We came across this case where a knee diffuse PVNS had invaded the bone, thus causing a conundrum in diagnosis. They may also be called osteochondritis dessicans or osteochondral fractures. The rationale for performing bone marrow-derived cell transplantation is based on the capability of these multipotent cells to differentiate and regenerate both the subchondral bone and the cartilaginous layer at the involved site. A layer of platelet-rich fibrin is ultimately applied over the membrane to provide growth factors at the site, as a further stimulus toward tissue regeneration. It’s most common in children and teens who are active in sports. Osteochondritis dissecans is a painful joint problem. https:// doi.
