They can start as bone bruising that develops into an osteochondral lesion. The surgical technique used involves a single surgical procedure that does not require harvesting any autologous material or using any type of fixation device. scaffold onto the lesion site, which was Franz König coined the term osteochondritis dissecans in 1887, describing it as an inflammation of the bone–cartilage interface. Once plugs have been chosen as the ideal technique the lesion is mapped with multiple diameter-sizing dowels to plan the reconstruction. Furthermore, the adult form, and in particular unstable lesions or those characterized by the presence of a loose body, have poor prognosis and therefore require a surgical approach to manage them. A joint surface damaged by OCD doesn’t heal naturally. T These cartilaginous injuries often occur in athletes and may significantly limit elite performance if left unaddressed. Such lesions are a tear or fracture in the cartilage covering one of the bones in a joint. Level of Evidence: Level IV, Case Series.

Patient- and lesion-specific factors must be identified when evaluating a patient with an articular cartilage defect. Osteochondral injuries are most common in adolescents and young adults. Minor cartilage damage may improve on its own within a few weeks, but more severe damage will often require surgery. This entire procedure is performed arthroscopically and involves a single surgical session. Among them, there is a three-layer scaffold developed by Fin-Ceramica Faenza Spa (Faenza, Italy) that has a porous 3-D composite structure that mimics the osteochondral anatomy. Once plugs have been chosen as the ideal technique the lesion is mapped with multiple diameter-sizing dowels to plan the reconstruction. However, since they were just recently developed and used in clinical practice, we only have results at short-term evaluations. [] Although majority may be associated with trauma, some may develop insidiously. should i go for a surgery ?

The damaged cartilage is removed and the lesion bed is prepared for treatment. 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. Lesions that were not limited to the cartilage occurred in 70% of the cases, while lesion thus limited accounted for 30%. Design: Osteochondral lesions (2.0 × 1.5 cm) were chiseled out on both condyles and trochlea in eight human cadaveric knees.

The scaffold obtained is then placed on the lesion site that has been previously prepared. The purpose of this study is to evaluate the outcomes of lesions treated with osteochondral allograft transplantation. Osteochondral defects are most commonly found in the thighs, shins and knees – areas that bear a lot of weight. It is known from long-term followup studies, such as those conducted by Linden, 7 that osteochondritis dissecans diagnosed in adulthood is likely to lead to the development of early onset osteoarthritis.

What is more, the entire pool of regenerative cells being used is concentrated directly in the operating room at the time of surgery, which eliminates the need for separate steps for cell selection and expansion. Knee Surg Sports Traumatol Arthrosc. A recent paper that my colleagues and I published in The Journal of Bone and Joint Surgery in 2012 reported the results of five different techniques to treat OCD. The need for treatment of concomitant cartilage lesions during patella instability surgery will be discussed in a later section. The aspirate is then immediately centrifuged to obtain bone marrow concentrate, which is loaded onto a membrane made of HA. Therefore, further studies are needed to confirm these encouraging, but preliminary results, and to determine whether longer follow-up will show similar results for all of these techniques or some evidence of the clear superiority of one of these options over the others. A review was performed of 30 athletes with 31 OLTs that were refractory to marrow stimulation or … Department of Orthopaedic Surgery, Stanford University Medical Center, Palo Alto, California. Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. To date, some osteochondral biomimetic scaffolds have been tested in clinical practice. While OCD may affect any joint, the knee tends to be the most commonly affected, and constitutes 75% of all cases. [2,3] Unfortunately, the poor healing potential of hyaline cartilage limits injury management. Cartilage is a connective tissue that covers the bones between joints. Recovery: Average recovery time after undergoing surgery to repair an osteochondral lesion of the talus ranges from four to six weeks. [] Although majority may be associated with trauma, some may develop insidiously. Its disadvantages lie in the fact that the cost of this procedure is high, and a mini-arthrotomy must be performed to implant these biomimetic osteochondral scaffolds. The first arthroscopic procedure is done both to harvest a cartilage sample for subsequent cultivation and to fill the bottom part of the lesion with autologous bone graft. Osteochondral lesions are commonly the result of excessive force going through the knee. Your email address will not be published.

While OCD may affect any joint, the knee tends to be the most commonly affected, and constitutes 75% of all cases. 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. Techniques such as microfracture, popularized by Steadman, [17, 18] and autologous chondrocyte transplantation have shown some promise. 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).

Most frequently it involves the medial femoral condyle (70%), the lateral femoral condyle (20%), the patella (5% to 10%) and the trochlea (<1%). Each surgical treatment has its pros and cons. Recent advance in biological knowledge introduced two different methodological approaches of delivering growth factors and stem cells into the articular environment. Anterior cruciate reconstruction combined with autologous osteochondral transplantation. Early knee osteoarthritis and chondral lesions are a common cause of disability in younger patients. Osteochondritis dissecans (OCD) is a problem that affects the knee, mostly at the end of the big bone of the thigh (the femur). A total of 24 bi-layer (5 mm, four in each condyle) or three-layer C-HA scaffolds (8 mm, eight in the trochlea, four in each condyle) were first press-fit implanted and underwent testing with CPM, 90 cycles, 0°-90°. 36(8) 891–900 The management of osteochondritis dissecans (OCD) requires a careful evaluation. In particular, bone-to-bone healing allows a faster recovery period compared with cartilage regeneration procedures. A total of 24 bi-layer (5 mm, four in each condyle) or three-layer C-HA scaffolds (8 mm, eight in the trochlea, four in each condyle) were first press-fit implanted and underwent testing with CPM, 90 cycles, 0°-90°. MRI showed that the osteochondral lesion had been filled, but the restored medial meniscus displayed increased degenerative changes and abra-sion (Fig 5).
