Fresh Osteochondral Allograft Transplantation for Treatment of Articular Cartilage Defects of the Knee.

ABSTRACT: Articular cartilage damage of the knee can cause severe morbidity. Owing to its avascular nature, articular cartilage has limited potential for self-healing and increased propensity to progress to osteoarthritis. Treatment of large, full-thickness cartilage defects is still a challenge for orthopaedic surgeons but has recently achieved high success rates with the use of osteochondral allografts. This article details our technique of osteochondral allograft transplantation for the treatment of articular cartilage defects of the knee.

Fresh Precut Osteochondral Allograft Core Transplantation for the Treatment of Femoral Cartilage Defects.

Project description:Fresh osteochondral allograft (OCA) transplantation is a successful single-stage procedure for the treatment of symptomatic cartilage defects of the knee. Although long-term studies reveal reliable improvements in patient-reported outcome scores and graft survival, the limitations of the procedure include graft availability and timely use prior to expiration. To avoid prolonged surgical wait times and progression of lesion size, some surgeons have employed the use of nonorthotopic grafts (e.g., lateral femoral condyle graft for a medial femoral condyle lesion). Additionally, fresh precut OCA cores can be used for smaller symptomatic lesions, thereby precluding surgical delays associated with donor-recipient size matching. We describe our preferred technique for the use of fresh precut OCA cores for the treatment of small osteochondral defects of the knee. The distinct advantages of this technique include single-stage restoration of the articular surface without the donor site morbidity observed with osteochondral autograft transplantation.

Bipolar Fresh Osteochondral Allograft Transplantation and Joint Reconstruction for Patellar and Trochlear Cartilage Defects.

Project description:Patellar instability is a debilitating condition, and trauma due to the dislocations may severely damage the articular cartilage of the patellofemoral joint. The lack of healing capacity of cartilage makes treatment of such lesions challenging. In young patients, preservation of native bone and cartilage is a priority, and therefore arthroplasty procedures should be avoided even in relatively larger lesions. Fresh osteochondral allografting has been described for these difficult and complex cases, with recent studies showing promising results. In this surgical technique, we describe the use of bipolar osteochondral allografts of the patella and trochlea and patellofemoral joint reconstruction for large bipolar full-thickness cartilage defects due to recurrent dislocation events.

Patellar Fresh Osteochondral Allograft Transplantation.

Project description:Chondral defects of the patellofemoral joint remain a difficult-to-treat pathology with limited long-term results. Currently available techniques to treat large or unipolar chondral defects of the patella include autologous chondrocyte implantation and osteochondral allograft transplantation. Despite the recent advances in orthobiologic adjuncts, there is no single gold-standard surgical approach to this difficult-to-treat pathology in patients who are frequently young, active, and demanding on their bodies. We describe a technique for osteochondral allograft transplantation to the patella for an isolated patellar chondral lesion (unipolar).

Fresh Osteochondral Allograft Transplantation in Osteochondritis Dissecans in the Knee Joint.

Project description:Osteochondritis dissecans (OCD) is a chronic and painful joint condition that can occur from childhood through to adult life. Microtrauma, vascular insufficiency, or abnormal endochondral ossification are the most common causes of OCD. Reconstructive techniques for OCD of the knee are typically necessary when either non-operative or reparative/regenerative operative treatments fail, or when the OCD is irreversible. To analyze the clinical outcomes and failure rates of fresh osteochondral allograft transplantation (FOCA) used as a reconstructive strategy in OCD patients, an in-depth search was carried out on the PubMed, Scopus, and Web of Science databases concerning the existing evidence related to the use of FOCA for OCD patients in the knee joint. A total of 646 studies were found through the search and 2 studies were added after a cross-referenced examination of the articles within the bibliography. Six studies with a total of 303 OCD lesions treated with FOCA, with a mean follow-up of 6.3 years, were included. Although a limited number of low-level evidence studies on this topic are available in previous research, satisfactory clinical results and survival rates of the reconstruction are reported. However, to better define the real advantages of FOCA in the healing process of OCD lesions, comparative studies with different techniques are needed.

Fresh Precut Osteochondral Allograft Core Transplantation for the Treatment of Capitellum Osteochondritis Dissecans.

Project description:Osteochondritis dissecans (OCD) of the elbow is a disease of unclear etiology that affects young children and adolescents, particularly overhead athletes and gymnasts. Common surgical options include fixation, debridement, loose body removal, and marrow stimulation (microfracture/drilling). For large, deep, and/or uncontained defects, osteochondral autograft transplantation (OAT) has been advocated. However, there are some drawbacks to OAT, particularly related to donor-site morbidity. Fresh osteochondral allograft (OCA) transplantation avoids the donor-site morbidity associated with OAT and has been shown to be effective for treating capitellar OCD. This Technical Note details a surgical technique of OCA transplantation of the capitellum in an adolescent patient using a fresh precut OCA core. This procedure addresses the cartilage defect and loss of subchondral bone associated with OCD without the drawbacks associated with harvesting an autograft. Furthermore, as the graft is readily available, it avoids delays related to the donor-recipient matching process.

Fresh Osteochondral Patellar Allograft Resurfacing.

Project description:The treatment of articular cartilage lesions in young patients is certainly a complex matter and subject of continuous research, particularly for those located at the patellofemoral joint, given its peculiar biomechanical characteristics. Osteochondral grafts can be of relatively small size when the defect is focal and in an area that allows good stability and consequently the graft's integration. In case of large or multifocal lesions, it is possible to consider an osteochondral transplantation of the entire articular surface of the patella. We present a simple and reproducible technique to perform a patellar fresh osteochondral allograft resurfacing attempting to reduce the symptoms and delay a prosthetic implant in young patients with advanced patellar chondral injuries.

Osteochondral Allograft Transplantation for Treatment of Focal Patellar Osteochondral Lesion.

Project description:Patellar osteochondral lesions are common and particularly disabling injuries that can affect young and highly active patients. If enough functional impairment, ranging from difficulty climbing stairs to pain with squatting, is present, surgical treatment may be warranted. For the treatment of these lesions, various techniques have been described, including autologous osteochondral transplantation, as well as microfracture surgery. However, these are not without disadvantages. Although morbidity is noted in cases of autologous osteochondral transplantation, uncertain and possibly unsustainable results are associated with the microfracture procedure. Therefore, we present an alternative surgical treatment option for this pathology. The objective of this Technical Note is to describe our preferred approach for an osteochondral allograft transplant procedure to treat a focal patellar osteochondral lesion.

Arthroscopic Particulated Juvenile Cartilage Allograft Transplantation for the Treatment of Osteochondral Lesions of the Talus.

Project description:Several options exist for the treatment of osteochondral lesions of the talus. Particulated juvenile cartilage allograft transplantation (PJCAT) has become a viable treatment modality for osteochondral lesions of the talus that are not amenable to microfracture or for which microfracture has failed. Arthroscopic placement of this type of graft obviates the need for osteotomy or plafondplasty and does not prevent additional procedures from being performed through an anterior approach. Special instrumentation and setup are not required to perform this procedure. Our arthroscopic technique for placement of particulated juvenile cartilage into osteochondral lesions of the talus is described. Case series and outcomes after arthroscopic ankle PJCAT are currently not reported within the literature; however, it is believed that the outcomes are at least similar to those of open ankle PJCAT.

Fresh osteochondral allografts for posttraumatic knee defects: long-term followup.

Project description:Fresh osteochondral allograft transplantation has been an effective treatment option with promising long-term clinical outcomes for focal posttraumatic defects in the knee for young, active individuals. We examined histologic features of 35 fresh osteochondral allograft specimens retrieved at the time of subsequent graft revision, osteotomy, or TKA. Graft survival time ranged from 1 to 25 years based on their time to reoperation. Histologic features of early graft failures were lack of chondrocyte viability and loss of matrix cationic staining. Histologic features of late graft failures were fracture through the graft, active and incomplete remodeling of the graft bone by the host bone, and resorption of the graft tissue by synovial inflammatory activity at graft edges. Histologic features associated with long-term allograft survival included viable chondrocytes, functional preservation of matrix, and complete replacement of the graft bone with the host bone. Given chondrocyte viability, long-term allograft survival depends on graft stability by rigid fixation of host bone to graft bone. With the stable osseous graft base, the hyaline cartilage portion of the allograft can survive and function for 25 years or more.

The cost-effectiveness of osteochondral allograft transplantation in the knee.

Project description:PURPOSE:Osteochondral allografts (OCA) consist of a layer of hyaline cartilage and a layer of underlying bone. They are used to repair combined defects of articular cartilage and bone. Such defects often occur in people far too young to have knee arthroplasty, for whom the main alternative to OCA is conservative symptomatic care, which will not prevent development of osteoarthritis. The aim of this report was to assess the cost-effectiveness of osteochondral allograft transplantation in the knee. METHODS:Systematic review of evidence on clinical effectiveness and economic modelling. RESULTS:The evidence on osteochondral allograft transplantation comes from observational studies, but often based on good quality prospective registries of all patients having such surgery. Without controlled trials, it was necessary to use historical cohorts to assess the effect of osteochondral grafts. There is good evidence that OCA are clinically effective with a high graft survival rate over 20 years. If an OCA graft fails, there is some evidence that revision with a second OCA is also effective, though less so than primary OCA. Economic modelling showed that osteochondral allograft transplantation was highly cost-effective, with costs per quality adjusted life year much lower than many other treatments considered cost effective. CONCLUSIONS:Osteochondral allograft transplantation appears highly cost-effective though the cost per quality adjusted life year varies according to the widely varying costs of allografts. Based on one small study, revision OCA also appears very cost-effective, but more evidence is needed. LEVEL OF EVIDENCE:II.
