Osteochondral fracture of the lateral femoral condyle involving the entire weight bearing articular surface fixed with biodegradable screws . Osteochondral lesions cause significant pain, discomfort, swelling, and reduced function in the knee joint. The cartilage can be torn, crushed or damaged and, in rare cases, a cyst can form in the cartilage. During the second arthroscopic procedure, the surgeon implants the expanded cultured chondrocytes, which were seeded onto a hyaluronic acid (HA) membrane. 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. Outcomes of osteochondral lesions of the knee repaired with a bioabsorbable device. We came across this case where a knee diffuse PVNS had invaded the bone, thus causing a conundrum in diagnosis. Arthroscopic microfracture is considered the primary treatment strategy for osteochondral lesions of the talus and has been shown to provide successful outcomes. Osteochondral Lesion … Key Words: Cartilage repair—Osteochondral grafting—Knee.

Injuries can range from a fine crack of the joint surface all the way though to a piece of the bone breaking away. Loose body is common: Talk to your dr. As loose body is very common. To date, some osteochondral biomimetic scaffolds have been tested in clinical practice. 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. 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. Anterior cruciate reconstruction combined with autologous osteochondral transplantation. 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. 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). 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. A radio-graph showed the disappearance of the bone defect and flattening of the femoral medial condyle (Fig 4). No conclusive indication of the superiority of one technique over the other was demonstrated in this trial. Damage such as small tears and fractures can be referred to as osteochondral lesions. An osteochondritis dissecans (OCD) lesion is seen prior to treatment. 59 years experience Internal Medicine. Osteochondral allograft (OCA) transplantation is an effective treatment option for chondral and osteochondral defects of the knee. Is Your Knee Pain Coming From a Meniscus Tear or Ligament Strain/Tear? 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°. In this review, we will focus on OCA and ACI as the mainstay in management of large chondral and osteochondral defects of the knee. Knee microfracture surgery is effective in providing significant relief for the symptoms that are caused … The osteochondral autologous transplantation (OAT) procedure done for large OCD lesions involves a single surgery and takes advantage of implanting mature autologous bone … 1 (A–C) Intraoperative views of an articular cartilage lesion on the medial femoral condyle. Seventeen patients Such lesions are a tear or fracture in the cartilage covering one of the bones in a joint. Design: Osteochondral lesions (2.0 × 1.5 cm) were chiseled out on both condyles and trochlea in eight human cadaveric knees. Osteochondral lesions are commonly the result of excessive force going through the knee. It is recommended that you avoid bearing weight until your ankle has healed. 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. 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. 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. Furthermore, ischaemia, abnormal ossification patterns and endocrine abnormalities have all been implicated as the potential … [4] Gökay Görmeli, MD1, Mustafa Karakaplan, MD1, Cemile Ayşe Görmeli, MD2, Baran Sarıkaya, MD3, Nurzat Elmalı, MD4, and Yüksel Ersoy, MD5, Clinical Effects of Platelet-Rich Plasma and Hyaluronic Acid as an Additional Therapy for Talar Osteochondral Lesions Treated with Microfracture Surgery: A Prospective Randomized Clinical Trial.

An osteochondral lesion is a defect in the cartilage of a joint and the bone underneath. 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. Lesions that were not limited to the cartilage occurred in 70% of the cases, while lesion thus limited accounted for 30%. Most frequently it involves the medial femoral condyle (70%), the lateral femoral condyle (20%), the patella (5% to 10%) and the trochlea (<1%). Osteochondral defects are most commonly found in the thighs, shins and knees – areas that bear a lot of weight. The etiology remains unclear; however, endocrine disorders, familial predisposition, vascular insufficiency, epiphyseal abnormalities and repetitive trauma have been investigated as concurrent causal factors.

Surgical treatment options for the management of focal chondral and osteochondral lesions in the knee include biological solutions and focal metal implants. Recent advance in biological knowledge introduced two different methodological approaches of delivering growth factors and stem cells into the articular environment. cartilage injury with associated subchondral fracture but without detachment However, due to great diversity in the articles and variability in treatment results, no definitive conclusions can be drawn. Larger lesions with progressive articular collapse and persistent pain may require surgery (often total knee arthroplasty). The American College of Cardiology decided to cancel ACC.20/WCC due to COVID-19, which was scheduled to take place March 28-30 in Chicago. PVNS is a rare condition affecting the joints and presence of a bone lesion in association with it is even rarer, especially in the knee joint. osteochondral lesions of the knee and talus in the athlete. Surgical treatment options for the management of focal chondral and osteochondral lesions in the knee include biological solutions and focal metal implants. Once plugs have been chosen as the ideal technique the lesion is mapped with multiple diameter-sizing dowels to plan the reconstruction. A bone marrow-derived cell transplantation procedure starts with the aspiration of bone marrow from the patient’s iliac crest. Key Words: Cartilage repair—Osteochondral grafting—Knee. Patient- and lesion-specific factors must be identified when evaluating a patient with an articular cartilage defect. 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. When there is a break, tear, separation, or disruption of the cartilage that could be referred to as an osteochondral lesion. Als osteochondrale Transplantation (Knorpel-Knochen-Transplantation) wird in der Orthopädie und Unfallchirurgie die Verpflanzung (Transplantation) eines gesunden Gelenkflächenabschnittes in den Bereich eines Knorpel- oder Knorpel-Knochendefektes bezeichnet.Die Transplantation kann autolog, aus körpereigenem Material oder homolog (Fremdgewebe) erfolgen. In particular, bone-to-bone healing allows a faster recovery period compared with cartilage regeneration procedures. A 16-year-old male asked: i am 16 y/o and i had been having pain in my knee(for 4-5 years).my report says osteochondral defect with a loose body. Klinger HM, et al.

The damaged cartilage is removed and the lesion bed is prepared for treatment. It usually occurs in the knee, ankle or elbow. A one-step treatment for chondral and osteochondral knee defects: clinical results of a biomimetic scaffold implantation at 2 years of follow-up. Early knee osteoarthritis and chondral lesions are a common cause of disability in younger patients. what are the causes? Surgery may involve removal of the loose bone and cartilage fragments within the joint and establishing an environment for healing. Fig. The surgeon treated the OCD lesion by How to Tell. However, the former actually does not … 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. 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. 529 We came across this case where a knee diffuse PVNS had invaded the bone, thus causing a conundrum in diagnosis. Clinics in Sports Medicine, January 1999, Vol. Knee surgery, sports traumatology, arthroscopy: official journal of the ESSKA, 18, 238–46. [] This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. Jobportal des Gelenk-Klinik MVZ. osteochondral lesion in the knee can be restored with OCT. How-ever, increased scintigraphic activity is introduced at the donor site, which becomes reduced with longer follow-up. The management of osteochondritis dissecans (OCD) requires a careful evaluation. 1. Osteochondral lesions or osteochondritis dessicans can occur in any joint, but are most common in the knee and ankle. If you've injured your joint and your symptoms are not too severe – for example, you're still able to put weight on and move the joint – you can often look after yourself using PRICE therapy. 78. The use of fairly large osteochondral plugs appears to correlate with retro-patellar crepitus and increased scintigraphic activity, and is not therefore recommended. 77. The osteochondral autologous transplantation (OAT) procedure done for large OCD lesions involves a single surgery and takes advantage of implanting mature autologous bone … The purpose of this study is to evaluate the outcomes of lesions treated with osteochondral allograft transplantation. 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. 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. Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. A review was performed of 30 athletes with 31 OLTs that were refractory to marrow stimulation or … 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. Arthroscopic synovectomy to remove the entire diseased synovium was performed along with curettage of the cyst, which resulted in a large osteochondral defect. A treatment gap exists for patients with lesions not suitable for arthroplasty or biologic repair or who have failed prior cartilage repair surgery. Overall, cartilage restoration techniques have yielded favorable clinical outcomes and can be successfully employed to treat these challenging large focal lesions.Thieme. Knee Surgery, Sports Traumatology, Arthroscopy, November 2003; 11(6): 366-371. 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. Further sufficiently powered, randomized clinical trials with uniform methodology and validated outcome measures should be initiated to compare the outcome of surgical … The bone right underneath the cartilage will also be injured.

While OCD may affect any joint, the knee tends to be the most commonly affected, and constitutes 75% of all cases. Cartilage is a connective tissue that covers the bones between joints. Arthroscopic synovectomy to remove the entire diseased synovium was performed along with curettage of the cyst, which resulted in a large osteochondral … 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. Multiple overlapping stamps or patches of the membrane can be positioned in the defect. Platelet-Rich Plasma and … The next day did MRI scans and X-rays and there was the release of free bone fragment in the knee joint and with apparent origin in the former osteochondral lesion. osteochondral lesions of the knee and talus in the athlete. Franz König coined the term osteochondritis dissecans in 1887, describing it as an inflammation of the bone–cartilage interface. The Lysholm knee score was 95. When compared to ACI, this technique is less expensive and it has further advantages because it requires a single surgical time. This paste is then used to cover the osteochondral defect. In case of wide lesion multiple plugs can be used to resurface the entire affected area, and in this case it is mandatory to proceed sequentially with … Recent advance in biological knowledge introduced two different methodological approaches of delivering growth factors and stem cells into the articular environment. 18, No. An osteochondral cyst can also be present following surgery. Furthermore, the technique requires an open surgical approach and there might be an anatomical discrepancy between the shapes of the donor site compared to the recipient site, which could prove problematic. Many osteochondral defects are caused by too much pressure on the joints and cartilage, and there are some cases where certain lifestyle changes and emphasis on joint health can help prevent these problems. org/ 10. In the management of large cartilage defects, the two classically utilized cartilage restoration procedures are osteochondral allograft (OCA) … All rights reserved.

We use cookies to ensure that we give you the best experience on our website. MRI scans were per-formed 12 and 24 months after surgery. 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. A treatment gap exists for patients with lesions not suitable for arthroplasty or biologic repair or who have failed prior cartilage repair surgery. Each surgical treatment has its pros and cons. Level of Evidence: Level IV, Case Series. Knee Surgery, Sports Traumatology, Arthroscopy, November 2003; 11(6): 366-371. Department of Orthopaedic Surgery, University Hospitals of Cleveland, Case Western Reserve University, Cleveland, Ohio. An Osteochondral lesion is an injury to the articular cartilage and the bone beneath it. In the paste-graft approach surgical technique, cartilage harvested from the margin of the intercondylar notch and cancellous bone harvested from the proximal aspect of the tibia are morselized to obtain a paste. [2,3] Unfortunately, the poor healing potential of hyaline cartilage limits injury management. The scaffold obtained is then placed on the lesion site that has been previously prepared. Surgical options, such as microfractures, ACI and OAT, provide good, but not fully satisfying, outcomes. Dr. Hany Elrashidy - Orthopedic Surgeon 31,310 views Osteochondral defects are most commonly found in the thighs, shins and knees – areas that bear a lot of weight. 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. Nevertheless, second-generation ACI in association with bone graft was confirmed as an extremely promising and reliable technique for cartilage repair in knees with OCD, with a trend toward achieving better results compared with non-regenerative techniques, such as massive OAT and bone-cartilage paste graft. However, since they were just recently developed and used in clinical practice, we only have results at short-term evaluations. Your email address will not be published. Many osteochondral defects are caused by too much pressure on the joints and cartilage, and there are some cases where certain lifestyle changes and emphasis on joint health can help prevent these problems. Large osteochondral defects involving the femoral condyles of the knee have frustrated orthopaedic surgeons for generations. Seventeen patients Performing a second-generation ACI procedure with bone grafting requires two arthroscopic surgical sessions. Osteochondral injuries are most common in adolescents and young adults. Arthroscopic ACI approaches have since revealed results similar to those of the open implantation technique, without as much morbidity. Chondral lesions of the knee are common, with a prevalence of more than 60% in those undergoing knee arthroscopy. Once plugs have been chosen as the ideal technique the lesion is mapped with multiple diameter-sizing dowels to plan the reconstruction. INTRODUCTION. They can start as bone bruising that develops into an osteochondral lesion. 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. Required fields are marked *. For this purpose, multi-layered biomimetic scaffolds and bone marrow-derived mesenchymal stem cells have been tested. Loose body is common: Talk to your dr. As loose body is very common. The need for treatment of concomitant cartilage lesions during patella instability surgery will be discussed in a later section. Patient Perspectives for Osteochondral Lesions. Klinger HM, et al.
