At an average follow-up of 4.2 years, 63% of the microfracture group had good or excellent outcomes, but this group had some deterioration in outcome over 1 to 4 years. Because clinical findings are often subtle, diagnosis requires a high index of suspicion. Reviewing these studies can provide useful information about the location, depth, and perimeter of the lesion. It is Osteochondral Defect. Osteochondritis dissecans (OCD) is a subchondral bone abnormality that affects the overlying articular cartilage with bony and cartilage fragmentation and may lead to degenerative changes. OSTEOCHONDRAL DEFECT. As a result, the small piece of bone and the cartilage covering it begin to crack and loosen. In patients with more advanced osteochondral pathology, the history frequently includes episodes of pain, mechanical symptoms, giving way, and swelling. Large defects cannot be filled due to donor site morbidity, and there may be problems with articular cartilage incongruence. Chondral and osteochondral lesions of the humeral capitellum, most notably osteochondritis dissecans, most commonly present in adolescent baseball players and gymnasts. O’Fallon, MO 63368, 660 S. Euclid Ave., Campus Box 8233, St. Louis, MO 63110, Center for Advanced Medicine - South County, St. Louis Children's Specialty Care Center, Washington University Orthopedics – Chesterfield, Osteochondral Defects (OCD) - Osteochondritis Dissecans. Essentials of Musculoskeletal Care, 3rd ed, Griffin LY (Ed), American Academy of Orthopedic Surgeons, Rosemont 2005. Osteochondral Defect listed as OCD Looking for abbreviations of OCD? Review of previous imaging studies (typically radiographs and/or magnetic resonance imaging [MRI]), operative reports, and arthroscopic imaging is critical in the evaluation of these patients. Osteochondraldefect is a broad term that describes the morphological change of a localized gap in the articular cartilage and subchondral bone 5. Osteochondral lesion of the talus (OLT) is a broad term used to describe an injury or abnormality of the talar articular cartilage and adjacent bone. ble fragment that was partially attached. 4921 Parkview Place The clinical presentation is characterised by an acute or chronic onset of symptoms. Looking for abbreviations of OCD? If you suffer an ankle sprain (or any kind of trauma to the ankle) and the cartilage fails to heal properly, bits of cartilage may break off and float around in the space between the bones in your ankle. Other options to be considered for cartilage loss are outlined in the following text, although some of them may have limitations especially in larger lesions and those with deep subchondral bone loss. Patient factors: Individual patient factors, including patient preferences, alignment of the lower extremities, social resources, work/job demands, and medical comorbidities must be considered when evaluating these patients. The etiology of OCD is not known, although many theories have been suggested, including trauma, vascular anomaly/injury, overuse or repetitive stress injury, genetic predisposition, etc. Please note that OCD is a commonly used abbreviation for both osteochondral defect and osteochondritis dissecans, two closely related conditions. This chapter focuses on the use osteochondral allografts to address these large, irreparable defects. Another multicenter case series using ACI for OCD demonstrated significant improvements, but more than a third of patients required secondary surgical débridement. Figure 1. Osteochondral defect. Amazon workers plan Black Friday strikes and protests. Marrow stimulation, although relatively simple to perform, has several limitations. Animals— Dogs (n=27) with medial humeral condylar OCD. The Department of Orthopaedic Surgery at Washington University School of Medicine in St. Louis has no control over third-party websites and does not review such websites. Suites 110 & 210 Chesterfield, MO 63017, 1044 N. Mason Road If surgery is further along, then sometimes we have to remove the offending part of the bone and stimulate healing of the cartilage surface. Restoring both bone and cartilage loss is especially challenging in larger lesions. Onset is between childhood and middle age, with the majority of patients being between 10 and 40 years of age, with approximately a 2:1 male to female ratio 3. Significant mechanical symptoms may not be addressed with this approach. Surgery can get quite technical and sometimes we bring cartilage and bone from the knee up to the elbow to restore these lesions, but other times at that stage, it can be very straight forward with a simple elbow arthroscopy where through a couple of poke holes, we can evaluate the lesion and institute treatment. OAT may have some advantages for treating OCD, as it can directly address the loss/abnormalities of subchondral bone. There are limitations to the OAT procedure. Articular Cartilage Defects of Knee ... osteochondral separation with loose bodies; Prognosis. Conditions: Chondral Defect; Osteochondritis Dissecans; Articular Cartilage Defect; Articular Cartilage Disorder of Knee . OCD - Osteochondral Defect. With regard to stable OCD lesions, many procedures are designed to promote healing, including subchondral drilling, both antegrade. For larger cartilaginous or osteocartilaginous defects, marrow stimulation, osteochondral autografts, and ACI have limitations. Osteochondritis dissecans is the most common cause of a loose body in the joint space in adolescent patients. Patients close to or beyond skeletal maturity have a worse prognosis for healing with activity modifications. In the talus, 96% of lateral lesions and 62% o… Most kids do well when they have this problem although we typically encourage the families to avoid the offending activity so if this seen in a high level gymnast and the elbow doesn't heal fully, that patient may or may not be able to get back to gymnastics as they performed before. In many of these patients, previous surgery and arthroscopic imaging have been performed. Suite 1500 For the mosaic osteochondral autograft transplantation group, 83% had good or excellent outcomes. A variety of surgical techniques can be used to address these lesions. Whether OLT is a precursor to more generalised arthrosis of the ankle remains unclear, but the … The use of autologous cartilage implantation (ACI) has been reported for treatment of OCD. Many of these injuries will include the medial or lateral femoral condyle, in both OCD and acute cartilage injury. Osteochondritis dissecans is an idiopathic disease which affects the subchondral bone and its overlying articular cartilage due to loss of blood flow. Causes MRI provides a more detailed look at the condition of the lesion and surrounding cartilage. The osseous component of the graft incorporates in the host bone through creeping substitution, in a manner similar to that seen with bone grafting for bone defects or allograft tumor reconstruction. A Study of MACI in Patients Aged 10 to 17 Years With Symptomatic Chondral or Osteochondral Defects of the Knee. Fixation of the osteochondral fragment was achieved with autogenous osteochondral plugs through a posterior arthrotomy. Osteochondritis Dissecans and Large Osteochondral Defects of the Knee Kevin G. Shea John Polousky Noah Archibald-Seiffer DEFINITION Osteochondritis dissecans (OCD) is a focal idiopathic alteration of subchondral bone with risk for instability and disruption of adjacent articular cartilage that may result in premature osteoarthritis. I'm an Orthopedic Surgeon at Washington University in St. Louis. The basic problem is likely to be poor blood supply to the capitulum or that distal part of the humerus and taking away the activities that cause the problem can lead to restoration, healing of the problem itself. Clot formation secondary to marrow stimulation produces disorganized fibrocartilage characterized by a high concentration of type I collagen rather than type II collagen, which comprises hyaline cartilage. Displaced osteochondral fragment. Long-standing radiographs are valuable in assessing limb length discrepancy and malalignment. The presence of a “kissing lesion” on the opposite articular surface is important, as its presence may alter or preclude certain allograft approaches. Nonoperative management may consist of activity modifications, maintenance of ideal body weight, and low-impact conditioning programs. The good news is that surgery can be very helpful depending on the type of specific injury we have. Hi, my name is Charles Goldfarb. Study design: Case series. These patients may describe the feeling of a loose body within the joint that can occasionally be palpated on the anterior aspect of the knee. Such lesions are a tear or fracture in the cartilage covering one of the bones in a joint. When I see a child with an OCD of the elbow, we initiate treatment by limiting activities and sometimes simply backing off on gymnastics or baseball may be enough to help control the symptoms and allow the elbow to heal. For the purposes of this article, the abbreviation OCD will be used only for osteochondritis dissecans. Regardless of etiology, osteochondritis dissecans is an idiopathic focal joint disorder affecting the subchondral bone. Osteochondral allograft transplantation has a long history, dating back to 1957, when Smillie proposed its use for OCD. Classification of osteochondritis dissecans of the capitellum Difelice GS, Meunier MJ, Paletta GA Jr. Elbow injury in the adolescent athlete. Both traumatic injuries and patients with OCD may present after months or years of milder symptoms. A variety of terms have been used to refer to this clinical entity, including osteochondritis dissecans (OCD), osteochondral fracture and osteochondral defect. The devices of MaioRegen system are indicated for the treatment of cartilage and osteochondral joint surface lesions . Osteochondritis dissecans differs from "wear and tear" degenerative arthritis, which is primarily an articular surface problem. The name osteochondritis dissecans (OCD) is a misnomer. Partially detached osteochondral fragment. This bone and cartilage can then break loose, causing pain and possibly hindering joint motion.Osteochondritis dissecans occurs most often in children and adolescents. Fresh osteochondral allografts address both the cartilage and bone deficits. Osteochondritis dissecans (os-tee-o-kon-DRY-tis DIS-uh-kanz) is a joint condition in which bone underneath the cartilage of a joint dies due to lack of blood flow. L.M. Clin Sports Med 1997; 16:157. AAOS Clinical Practice Guideline: diagnosis and treatment of osteochondritis dissecans. In 1888, Konig coined the term when he sought to describe the pathologic process that led to atraumatic loose bodies of femoral origin in the knee and hip joints. Osteochondritis dissecans of the distal femur and patella. A trauma with subsequent osteochondral defect detected immediately by radiology has to be differentiated from osteochondritis dissecans of the talus. Osteochondritis dissecans (OCD) is a condition that develops in joints, most often in children and adolescents. Conclusion: Osteochondritis dissecans (OCD) rarely affects the glenoid. Completed. Some research has also shown factors such as age older than 30 years and a history of two or more previous surgeries on the joint are associated with poorer outcomes. Cases in which the cartilage damage is so severe that the fragment is unsalvageable, osteochondral defects may be addressed with a variety of cartilage restoration procedures. Osteochondral Defect Osteochondritis Dissecans Osteochondral Lesions. St. Louis, MO 63129, 20 Progress Point Parkway, Suite 114 In a prospective randomized trial, mosaic osteochondral autograft transplantation demonstrated superior result compared to microfracture for the treatment of OCD in children and adolescents. At 8 months after surgery, the patient was able to return to his former competitive level of performance. Patients with acute, traumatic cartilage injury with displaced fragments may be candidates for surgery. Chambers HG, Shea KG, Carey JL. Osteochondritis Dissecans and Avascular Necrosis Matthew T. Burrus David R. Diduch DEFINITION Osteochondritis dissecans (OCD), avascular necrosis (AVN), spontaneous osteonecrosis of the knee, and chondral and osteochondral lesions all occur at or beneath the articular surface of a weight-bearing joint and are easily confused (FIG 1). The older patients may not respond to less invasive surgeries such as subchondral bone drilling. Osteochondritis dissecans of the talus is a particular form of osteochondral lesions of the talus. The university disclaims any responsibility for the content of third-party websites and the As mentioned, one challenge with mosaic osteochondral autograft transplantation is donor site morbidity as well as the differences in cartilage thickness in donor and recipient sites. Study Design— Case series. Osteochondral lesions or osteochondritis dessicans can occur in any joint, but are most common in the knee and ankle. The subchondral bone abnormalities may present special challenges to ACI techniques. Due to the loss and/or abnormalities of the subchondral bone base, special ACI approaches have been developed. Notable findings include effusion, joint line tenderness, and, in some cases, a mobile free body may be palpated. Town and Country, MO 63017, 14532 S. Outer Forty Drive Osteochondritis Dissecans and Large Osteochondral Defects of the Knee. This may result in separation and instability of a segment of cartilage and free movement of these osteochondral fragments within the joint space.That process can lead to pain, loose body formation and joint effusion. If the lesion is not very far progressed, then surgery can be a cleanup type procedure. Osteochondritis Dissecans Typically, a sports injury due to stressful twisting motions of the shinbone or thighbone, osteochondritis dissecans is any damage to the cartilage coating of the bone. Acute traumatic injuries can cause displacement of preexisting OCD lesions or the development of acutely displaced cartilage fragment on otherwise normal bone and cartilage structures. Nail salons, a lifeline for immigrants, begin shuttering In: Altchek DW, Andrews JR, eds. Some of these injuries can be osteochondral lesions such as osteochondral defects, osteochondrosis of the capitulum humeri or osteochondritis dissecans (OCD). Seymour, 69, clarifies remark on being able to play 25. Fragmentation of a small focus of subchondral bone creates a defect between the osteochondral lesion and the parent bone, leading to decreased vascularization and resulting in osteonecrosis of the fragment. 6th Floor, Suites A & B; 12th Floor, Suite A Objective— To establish whether osteochondral autograft transfer (OAT) procedures for osteochondritis dissecans (OCD) of the canine elbow would restore articular contour, resurface osteochondral defects with hyaline cartilage, and resolve lameness in the short term. A wealth of information can be gleaned from properly performed radiographs, including the approximate dimensions and location of the lesion and the precedence of diffuse osteoarthritis. This approach may be reasonable for smaller OCD lesions. Animals: Dogs (n=14) with caudocentral humeral head OCD (16 shoulders). Osteochondritis dissecans (OCD) is a focal idiopathic alteration of subchondral bone with risk for instability and disruption of adjacent articular cartilage that may result in premature osteoarthritis. prognosis correlates with . In addition, osteochondral allografts produce enough graft material to resurface larger lesions. Completely detached osteochondral fragment remaining in the crater. Restoring this subchondral bone loss can present many challenges to the surgeon, both with microfracture, and other cartilage restoration procedures. In clinical practice, the abbreviation OCD is often used for both osteochondral defect and osteochondritis dissecans, which causes confusion. Objective: To establish whether osteochondral autograft transfer (OAT) procedures for osteochondritis dissecans (OCD) of the canine caudocentral humeral head would restore articular contour, resurface osteochondral defects, and resolve lameness in dogs with OCD. Osteochondral defect is a detachment of bone and cartilage in a joint that can cause pain. The cartilage can be torn, crushed or damaged and, in rare cases, a cyst can form in the cartilage. Background: Costal osteochondral grafting is a technique to achieve anatomical and biological repair of articular defects. For patients that have focal, full-thickness cartilage defects, several techniques can be used to restore the joint cartilage surface. St. Louis, MO 63110, One Children's Place One common abnormality I see in the elbow is something called an OCD or an Osteochondral Defect. Suite 1B In cases with more significant loss of subchondral bone, staged procedures to supplement regional bone loss may be an option. The authors prefer standing anteroposterior, tunnel, lateral, and Merchant views. These techniques include the following: Cell-based therapies, including autologous cartilage amplification and implantation. The most valuable tools for evaluating osteochondral lesions are high-quality imaging studies, the most basic of which is the weight bearing, plain radiograph of the knee. Significant osteoarthritis, especially if more diffuse, rather than focal, may be a contraindication to osteochondral allograft use. St. Louis, MO 63141, 5201 Midamerica Plaza NCT03588975. The use of a fresh osteochondral allograft for treatment of a lesion of the femoral condyle is relatively new, and we report its use in a unique situation involving identical twins who both presented with osteochondritis dissecans of the same anatomic location within 2 years of each other. It is typically thought to be an overuse abnormality of the outside of the elbow or a part of the humerus bone called the capitulum. If that fails to lead to improvement or if there are mechanical symptoms, which is the locking or catching of the elbow, then we have to think more aggressively and typically that involves surgical intervention. 1. repetitive throwing / valgus stress and gymnastics / weight bearing on upper extremity 1.1. valgus stress / compressive force on the vulnerable chondroepiphysis of the radiocapitellar joint in skeletally immature patients is supported as the aetiology for OCD of the capitellum 8 2. ankle sprain/instability 2.1. Consequently, in lesions that are small, mosaic osteochondral autograft transplantation is a reasonable procedure that produces outcomes that are superior to microfracture. The rationale for fresh osteochondral allograft transplantation is to replace diseased, unsalvageable bone, and cartilage defects in the context of an otherwise healthy joint. Recruiting . Evaluation of the Agili-C Biphasic Implant in … The arrow points to the evolving osteochondral defect involving the capitellum typical of osteochondritis dissecans. Stable fragments are those that are held in place by intact … Suite 1C The prevalence of OCD is approximately 15 to 29 cases per 100.000; male patients are affected more … Microfracture may not have a role in the treatment of osteochondritits dissecans if the subchondral bone is violated. One common abnormality I see in the elbow is something called an OCD or an Osteochondral lesions, also known as osteochondritis dissecans, are areas of damaged bone and cartilage on the surface of the ankle bone (the talus), usually caused by an ankle injury. Fibrocartilage lacks the mechanical integrity and ultrastructural organization of hyaline cartilage and often deteriorates after a few years. Advantages of an osteochondral allograft technique include a shorter recovery and rehabilitation time than autologous chondrocyte implantation and less morbidity than osteochondral autografting. For patients in whom native cartilage and bone cannot be successfully repaired, or those that have failed previous attempts at repair of native tissue, osteochondral allograft is one option to be considered. Careful inspection for malalignment, kissing lesions, or signs of more diffuse cartilage injury is essential, as these factors may change the surgical management of the patient. The living chondrocytes from the transplant become a viable part of the recipient’s cartilage matrix, and the transplanted bone is incorporated by the host bone. Many patients, especially those who are skeletally immature, with significant growth remaining, have good potential for healing with appropriate activity modification, and in select cases, subchondral bone drilling. J Am Acad Orthop Surg 2011; 19:307. juvenile form. NCT01471236. Osteochondral autograft transfer has recently shown superior rates of return to sport. was next seen once month later where he reported a 50% reduction in pain and stiffness. Definition and symptoms. Some patients may be referred to a doctor for further diagnosis. use of any information on these sites. age younger age correlates with better prognosis; open distal femoral physes are the best predictor of successful non-operative management ; location lesions in lateral femoral condyle and patella have poorer prognosis; appearance . OCD lesions occur when a segment of subchondral bone… It is often used synonymously with osteochondral injury/defect in the pediatric population. Osteochondral tissue harvested from fresh allograft talus and transplanted into the defect Best for large (>3 cm 2 ) lesions, as an alternative to arthrodesis ( 10 ) 66% success rate ( 11 ) Collagen-covered ACI (ACI-C) has been described in a case series, showing positive clinical results at 4 years, but most cases that underwent biopsy revealed fibrocartilage. MaioRegen Prime (tri-layer) is indicated for the treatment of single/multiple osteochondral lesions with severely compromised bone, Outerbridge Grade IV. In addition to poor wear properties, the fibrocartilage formed after marrow stimulation may not restore congruity of the articular surface in cases of OCD, where loss of the subchondral bone and débridement of fibrous tissue results in a deep crater with significant bone loss. The natural history of OCD runs a variable course. The other name that gets associated with this problem is Osteochondritis Dissecans. Some small series of clinical applications of this procedure for advanced osteochondritis dissecans of the humeral capitellum, with short-term follow-up, have been reported; however, longer-term outcomes remain unclear. It is Osteochondral Defect. An osteochondral defect of the femoral condyle ( ) may be the result of several acute and chronic conditions that produce a surface … It can be in the dominant hand or the non-dominant hand and it typically causes pain but also can cause other problems which we call mechanical problems which include locking of the elbow, popping in the elbow and an inability to perform daily activities. There were 41% failures in the microfracture group compared with none in the mosaic osteochondral autograft transplantation group at the final follow-up. We see it most commonly in gymnasts and also in baseball pitchers, although we can see it in any child in any sport. Once your diagnostic examination is complete, the Physical Therapists at Rocky Mountain Therapy Services have treatment options that will help speed your recovery, so that you can more quickly return to your active lifestyle. In cases in which the subchondral bone is minimally involved, standard ACI may be considered. Lesions can be f traumatic, post-traumatic or degenerative origin, as well as caused by osteochondritis dissecans … OCD and other traumatic injuries can lead to large osteochondral defects of the knee. Diagnosis of osteochondritis dissecans (OCD) is generally made during the history and physical examination. The depth of the osteochondral autograft donor plug can be adjusted to fill the entire defect with viable bone and articular cartilage, which has the capacity to integrate with the adjacent tissue. Conditions: Osteochondral Defect; Osteochondritis Dissecans . Instead, OCD is a problem of the bone underlying the cartilage, which may secondarily affect the articular cartilage. I see patients at the Orthopedic Center of Chesterfield, St. Louis Children's Hospital and the Shriner's Hospital for Children.

The MRI may also reveal kissing lesions, in which there is chondral injury on opposing articular surfaces. 1 Although the etiology remains unclear, repetitive microtrauma is the most accepted theory. St. Louis, MO 63110, 13001 N Outer Forty Road It occurs when a small segment of bone begins to separate from its surrounding region due to a lack of blood supply. Kids born with hand and upper extremity abnormalities often come to these sites to see me for evaluation and treatment. Osteochondritis dissecans (o.d.) The defect is stable without evidence of in situ loose body. The technique precludes filling the entire defect when multiple grafts are used and fibrocartilage forms around the periphery of the grafts. He was now able to perform all activities of daily living without pain, including weight lifting, running, and swimming.
