Most frequently it involves the medial femoral condyle (70%), the lateral femoral condyle (20%), the patella (5% to 10%) and the trochlea (<1%). It’s most common in children and teens who are active in sports. Klinger HM, et al. A review was performed of 30 athletes with 31 OLTs that were refractory to marrow stimulation or … MRI showed that the osteochondral lesion had been filled, but the restored medial meniscus displayed increased degenerative changes and abra-sion (Fig 5). Arthroscopic synovectomy to remove the entire diseased synovium was performed along with curettage of the cyst, which resulted in a large osteochondral defect. Lesions that were not limited to the cartilage occurred in 70% of the cases, while lesion thus limited accounted for 30%. 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.

[] This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. In the management of large cartilage defects, the two classically utilized cartilage restoration procedures are osteochondral allograft (OCA) transplantation and cell therapy, or autologous chondrocyte implantation (ACI). However, ACC.20/WCC Virtual Meeting continues to release cutting edge science and practice changing updates for cardiovascular professionals on demand and free through June 2020. The cartilage can be torn, crushed or damaged and, in rare cases, a cyst can form in the cartilage. osteochondral lesions of the knee and talus in the athlete. The use of fairly large osteochondral plugs appears to correlate with retro-patellar crepitus and increased scintigraphic activity, and is not therefore recommended.

This entire procedure is performed arthroscopically and involves a single surgical session. Once plugs have been chosen as the ideal technique the lesion is mapped with multiple diameter-sizing dowels to plan the reconstruction. To date, some osteochondral biomimetic scaffolds have been tested in clinical practice. Looking at the nanostructured scaffold, the rationale for its use is based on the capability of particular biomaterials to induce in situ tissue regeneration that is carried out by stem cells originating from the surrounding bone marrow. The scaffold obtained is then placed on the lesion site that has been previously prepared. 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. The structure of this scaffold helps confine bone formation to the deepest portion of the lesion and cartilage regeneration to the surface of the area without the need for introducing any cell or growth-factor supplements to the surgical site. Damage such as small tears and fractures can be referred to as osteochondral lesions.

Because of the relatively high cost of ACI and the knee morbidity seen in OATS, we conclude that BMS is the treatment of choice for primary osteochondral talar lesions. 78. Recent advance in biological knowledge introduced two different methodological approaches of delivering growth factors and stem cells into the articular environment. Once plugs have been chosen as the ideal technique the lesion is mapped with multiple diameter-sizing dowels to plan the reconstruction. Send thanks to the doctor. 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. Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. In the knee, such cartilage damage can occur between the femur (thigh bone) and the tibia (shin bone). Seventeen patients A radio-graph showed the disappearance of the bone defect and flattening of the femoral medial condyle (Fig 4). Arthroscopic microfracture is considered the primary treatment strategy for osteochondral lesions of the talus and has been shown to provide successful outcomes.

Large, focal articular cartilage defects of the knee (> 4 cm) can be a source of significant morbidity and often require surgical intervention. The surgical technique used involves a single surgical procedure that does not require harvesting any autologous material or using any type of fixation device. 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. 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.

Chondral lesions of the knee are common, with a prevalence of more than 60% in those undergoing knee arthroscopy. Kon E. et al. We came across this case where a knee diffuse PVNS had invaded the bone, thus causing a conundrum in diagnosis. Surgery may involve removal of the loose bone and cartilage fragments within the joint and establishing an environment for healing. Larger lesions with progressive articular collapse and persistent pain may require surgery (often total knee arthroplasty). Multiple overlapping stamps or patches of the membrane can be positioned in the defect. Patient Perspectives for Osteochondral Lesions. Klinger HM, et al.

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. 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. 1. OCD Lesion – Knee Arthroscopy with Cartilage Repair and Regeneration - Duration: 5:06. Subchondroplasty, a procedure developed to treat bone marrow edema lesions by injecting a bone substitute, is one of the evolving treatment options for patients with SIF.
