Platelet-Rich Plasma and … A clinical assessment was performed using VAS score, Lysholm score, and Tegner activity level after an average follow-up of 27 months (SD: 2.3). However, due to great diversity in the articles and variability in treatment results, no definitive conclusions can be drawn. For this purpose, multi-layered biomimetic scaffolds and bone marrow-derived mesenchymal stem cells have been tested. T These cartilaginous injuries often occur in athletes and may significantly limit elite performance if left unaddressed. A radio-graph showed the disappearance of the bone defect and flattening of the femoral medial condyle (Fig 4). Osteochondral Lesion … INTRODUCTION. Alternative techniques that are available or currently in clinical trials include a hyaluronan-based scaffold plus bone marrow aspirate concentrate, a third-generation autologous chondrocyte implant, and an aragonite-based scaffold. The aforementioned 2012 study in The Journal of Bone and Joint Surgery assessed the clinical outcomes of these five different surgical techniques in patients affected by OCD of the knee, at a mean follow-up of 5 years. 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. implanting a biomimetic osteochondral 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. Is Your Knee Pain Coming From a Meniscus Tear or Ligament Strain/Tear? Seventeen patients Larger lesions with progressive articular collapse and persistent pain may require surgery (often total knee arthroplasty). 77. Berruto M. et al.

The osteochondral autologous transplantation (OAT) procedure done for large OCD lesions involves a single surgery and takes advantage of implanting mature autologous bone and cartilage, which have excellent survival rates. In the study by Widuchowski et al (14), some type of chondral lesion was found in 60% of the knees operated, of which 67% were classified as osteochondral or chondral lesions, 29% as osteoarthritis, 2% as osteochondritis dissecans and 1% as other types. Osteochondral lesions or osteochondritis dessicans can occur in any joint, but are most common in the knee and ankle. 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. Department of Orthopaedic Surgery, University Hospitals of Cleveland, Case Western Reserve University, Cleveland, Ohio. Am J Sports Med (2014). Knee Surg Sports Traumatol Arthrosc. Fig. On the other hand, the amount of graft that a donor site can provide is limited and that also determines the so-called “donor site” morbidity, of which surgeons should be aware. This paste is then used to cover the osteochondral defect. The use of fairly large osteochondral plugs appears to correlate with retro-patellar crepitus and increased scintigraphic activity, and is not therefore recommended. Once plugs have been chosen as the ideal technique the lesion is mapped with multiple diameter-sizing dowels to plan the reconstruction. 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. In the management of large cartilage defects, the two classically utilized cartilage restoration procedures are osteochondral allograft (OCA) … They may also be called osteochondritis dessicans or osteochondral fractures.
