Nonsurgical treatment also presents challenges because it is difficult to predict which stable juvenile ocd lesions will heal. Imaging, ocd is a radiologic diagnosis. If ocd of the knee is suspected, ap, lateral, notch-view (knee in flexion) and skyline patella xrays should be ordered. Ap films alone may miss a lesion on the posterior aspect of the medial femoral condyle. If a lesion is seen the contralateral knee should also be xrayed. Plain films will detect a circumscribed area of necrosis but are a poor method of assessing articular cartilage and cannot be used to determine stability. If the xrays are normal the diagnosis is almost certainly not l ocd lesions seen on xray should be staged for stability with mri. Mri has a 97 percent sensitivity for detecting unstable lesions.
100,000 in males and 18 per 100,000 in females). Ocd can involve other joints including the shoulder, elbow, hip, and ankle, but the knee is the most commonly affected. The natural history of ocd of the knee remains unclear and distinguishing between those lesions that may go on to heal and those that will not heal remains a challenge. High quality diagnostic, prognostic, and therapeutic studies that reported data separately for adults and children are rare. Many of the publications dealing with ocd of the knee are level iv evidence (case series). Treatment, the primary goals of treatment are to relieve pain, improve knee function, and prevent progression of the degenerative joint process. As with all surgical procedures the risks include infection, bleeding, dvt and persistent pain. The newer arthroscopic approaches have a relatively low risk compared to more invasive approaches but the more invasive treatments to salvage and/or reconstruct the cartilage and/or bone are still sometimes required.
Ocd predominantly affects adolescent and young adult patients. Many of these patients are involved in houden athletic persuits and this condition can have a dramatic impact on them. Ocd can lead to pain, swelling, mechanical symptoms and inability to continue to play sports and is the most common cause of a loose body in the knee in adolescents. Clinical findings are often subtle so diagnosis requires a high index of suspicion and limited range of motion may be the only clinical sign. Most patients provide a history of trauma as their reason for their presentation but this is usually minor and probably not relevant. In some patients the affected femoral condyle is tender on palpation and the patient may walk with the leg externally rotated in order to avoid impingement of the lesion on the medial femoral condyle. How is ocd diagnosed? The diagnosis is made on xray but mri has a key role in determining the stability of the lesion. Conservative management is the mainstay of treatment for stable lesions. The majority of patients respond to conservative treatment but those with unstable lesions require arthroscopic management. Unfortunately the affected knee may progress to degenerative arthritis while the patient is still young.
Osteochondral defects - foot and Ankle - oxford University hospitals
Osteochondritis dissecans of the knee (OCD) is a condition in which cracks form in the articular cartilage (joint lining) because of a problem with the underlying bone. We dont understand exactly why but the blood supply to the bone near the joint (subchondral bone) is interrupted. This loss of blood flow causes the subchondral bone to die in a process called avascular necrosis. The bone is then reabsorbed by the body leaving an empty hengstig space under the articular cartilage. The articular cartilage is not directly affected by the lack of blood supply because it gains its nutrition from the synovial fluid in the joint. Unfortunately the loss of structural support for the articular cartilage allows it to crack and fragment. This results in loss of the smooth joint lining surface and sometimes movement of these osteochondral (bone and cartilage) fragments within the joint. There are two main types of ocd: the adult form, which occurs after the physis closes (growing art of the bone and the juvenile form, which occurs in patients with an open epiphyseal plate (some people believe that the adult form is undiagnosed persistent juvenile.

Patients who were treated with surgical cartilage procedures showed durable function and symptomatic improvement at a mean of 4 years follow-up. Patients treated with arthroscopic reduction and internal fixation and loose-body removal had greater improvement in outcome scores than those treated with an osteochondral allograft. Seven knees required revision procedures at a mean follow-up of 14 months. 2, adachi et al evaluated the functional and radiographic outcome of retroarticular drilling without bone grafting in 12 patients with juvenile osteochondritis dissecans after 6 months of unsuccessful nonoperative treatment. The mean Lysholm score significantly improved postoperatively (from.3.8). All lesions except 1 healed after retroarticular drilling, and healing was achieved at a mean.4 months on plain radiographs and.6 months on magnetic resonance imaging.
3, kijowski et al retrospectively compared the sensitivity and specificity of previously described magnetic resonance imaging criteria for the detection of instability in patients with juvenile or adult osteochondritis dissecans of the knee, with arthroscopic findings as the reference standard. Separately, previously described mr imaging criteria for detection of ocd instability were 0-88 sensitive and 21-100 specific for juvenile ocd lesions and 27-54 sensitive and 100 specific for adult ocd lesions. When used together, the criteria were 100 sensitive and 11 specific for instability in juvenile ocd lesions and 100 sensitive and 100 specific for instability in adult ocd lesions. The authors concluded from their findings that previously described mr imaging criteria for ocd instability have high specificity for adult but not juvenile lesions of the knee.

With the advent of roentgenography, osteochondrotic conditions in other joints, primarily the hip, were recognized. In 1910, legg, calvé, and chiropractor Perthes independently identified a condition of the hip joint in children, which is now known. In 1921, waldenström introduced the term coxa plana (ie, disintegration of capital femoral epiphysis.). Since the introduction of radiography, 50 additional anatomic sites within the body where ocd can occur have been identified. Recent studies, tabaddor et al evaluated the efficacy and safety of poly 96L/4D-lactide bioabsorbable copolymer fixation for unstable ocd in 24 adolescents (mean age,.4 y). Plain films at an average.2 months after surgery showed interval healing in 9 patients, no significant change in 1, complete healing in 13, and loose bodies with no interval healing. Mris showed interval healing in 16 of 17 knees at a mean follow-up.4 months. 1, pascual-Garrido et al examined the outcomes of surgical procedures for osteochondritis dissecans in 46 adult patients (48 knees with patients ranging in age from 20 to 49 years.

Osteochondritis dissecans (ocd by definition, is a disorder of one or more ossification centers, characterized by sequential degeneration or aseptic necrosis and recalcification. Ocd lesions involve both bone and cartilage. These lesions differ from acute traumatic osteochondral fractures; however, they may manifest in a similar fashion. Ocd lesions also must be differentiated from meniscal pathology. Ocd causes 50 of loose bodies in the knee. The etiology of these lesions is multifactorial, including trauma, ischemia, abnormal ossification centers, genetic predisposition, or some combination of these factors. Little agreement exists among researchers regarding the etiology of ocd. Images of osteochondritis dissecans of the knee are halverwege provided below: Anteroposterior and lateral radiographs of medial femoral condyle osteochondritis dissecans.
