[4-6] Treatment of these lesions has been reported extensively previously, but as stated by Dahmen et al. If the lesion is stable (without loose pieces of cartilage or bone), one or more of the following non-surgical treatment options may be considered: 1. HOW TO TELL IF YOU HAVE A STRESS FRACTURE? However, medial lesions are more common than lateral OCLs. These incidents can be a singular, acute macrotraumatic incident, or a repet-itive, cumulative microtrauma-induced event. Non-operative treatment can be successful for non-displaced talar OLTs, especially if the condition is recognized and treated early, and the lesion is relatively small. Initial x-rays are taken to check the alignment of the foot and ankle, as well as look for any bone damage. suggested internal fixation of the lesion if it is larger than one third of the size of talar dome while Stone et al. They require a strong plan. Talar dome lesions generally involve either the superomedial or superolateral corners of the talus. However, most radiographs do not show symptoms of the osteochondral lesion. Please call our office at 972-274-5708 to schedule an appointment. Although one might expect a loose lesion to cause mechanical symptoms, complaints of locking, catching, or swelling are less common, except when a lateral lesion has caused an acute loose body to be formed. 10. Immobilization – Depending on the type of injury, the leg may be placed in a cast or cast boot to protect the talus. Furthermore, many lesions are located in the posterior part of the talar dome. Physiotherapy treatment is vital for all patients with an osteochondral lesion of the talar dome to maximise the healing process, ensuring an optimal outcome and to reduce the likelihood of recurrence. How are talar dome lesions treated? The surgical technique allows preservation of intact articular cartilage, in contrast to traditional methods. Introduction The patient presented with a history of a medial talar dome osteochondral lesion (OCL) for over five years prior to her first microfracture surgery in 2008. If the lesion is stable (without loose pieces of cartilage or bone), one or more of the following non-surgical treatment options may be considered: Immobilization. in 1984 emphasized that these lesions should not be called as osteochondritis dissecans but be grouped under a broader term “osteochondral lesions of the talar dome.” The arthroscopic treatment of these lesions was first described by Parisien and Pritsch et al. Talar dome lesion treatment options. If you catch your talar dome lesion in its early stages, your podiatrist uses nonsurgical treatments to heal your joint. Younger patients, particularly growing children or adolescents, have a much better chance of healing an OLT compared to adults. J Bone Joint Surg Am. The ankle joint is composed of the bottom of the tibia (shin) bone and the top of the talus (ankle) bone. The patient will usually report a distinct episode of trauma when a lateral lesion is present, but with medial lesions there may be no specific injury or the common historical association of one or more ankle sprains in the past. A retrospective study of 22 ankles in 22 patients with osteochondral talar dome lesions between 1975 and 1983 has indicated that surgical treatment yields superior results to conservative therapy. Lesions can be graded based on their radiological findings. Treatment depends on the severity of the talar dome lesion. 1986 Jul. Unless the injury is extensive, it may take months, a year, or even longer for symptoms to develop. Procedure selection is generally based on lesion size, location on the talar dome and/or a history of prior failed surgical management. Depending on the type of injury, the leg may be placed in a cast or cast boot to protect the talus. The decision for arthroscopic intralesional curettage was only done when the cyst diameter was 10 mm or more in the preoperative CT scan. Foot Ankle Clin. Sixteen patients (16 ankles) with symptomatic osteochondral lesions of the medial talar dome were treated arthroscopically with percutaneous retrograde drilling through the sinus tarsi. Treatment of Osteochondral Lesions of the Ankle. If non-surgical treatment fails to relieve the symptoms of talar dome lesions, surgery may be necessary. Sometimes a broken piece of the damaged cartilage and bone will “float” in the ankle. Patients frequently present with an acute injury and positive radiographic findings. Treatment depends on the severity of the talar dome lesion. A variety of surgical techniques is available to accomplish this. Surgery may involve removal of the loose bone and cartilage fragments within the joint and establishing an environment for healing. In contrast to the historically described anterolateral and posteromedial locations, the midtalar dome was involved in 80% of lesions. Autologous cartilage was then reimplanted arthroscopically. The only exception is in the case of a loose talar dome lesion, which will present on radiographs with a fleck of cartilage and bone loose or floating in the joint. Credit for originally describing OLTs of the ankle is given to Alexander Monro, 1 in his description in 1738. A varietyof surgical techniques is available to accomplish this. Surgery may involve removal of the loose bone and cartilage fragments within the joint and establishing an environment for healing. lesions and 70% of medial lesions are associated with trauma based on Flick and Gould’s7 review of more than 500 documented talar dome lesions. There is an association with trauma to the ankle, particularly in lateral talar dome lesions. Surgery may involve removal of the loose bone and cartilage fragments within the joint and establishing an environment for healing. They require a strong plan. Talar dome lesions are usually caused by an injury, such as an ankle sprain. Pritsch M, Horoshovski H, Farine I. Arthroscopic treatment of osteochondral lesions of the talus. Defined as a separation of articular cartilage from the talar dome, with varying amounts of subchondral bone. CT staging again mimics the plain radiographic and MRI evaluations and also incorporates evaluation of the cystic component (. Although studies show these treatments have been used with varying success, the ability to return to activity (RTA), including sports after treatment of talar dome injurie s, have not been well documented. TABLE 49-1 Berndt and Harty Classification: Osteochondral Lesions of the Talar Dome, TABLE 49-2 Anderson et al. Because the MRI is very sensitive in, CT is the most precise means of evaluating the bone lesion itself. Treatment decisions are based upon the site of the lesion, the size of the lesion, the skeletal maturity of the patient, the quality of the articular cartilage, and the quality of the associated bone fragment. An osteochondral lesion to the talar dome is an injury that causes damage to the cartilage that sits on top of the talus. From Berndt AL, Harty M. Transchondral fractures (Osteochondritis Dissecans) of the talus. In addition, the mortise view may be obtained in plantar flexion to better assess a posteromedial lesion or in dorsiflexion to assess an anterolateral lesion. Compared with lateral lesions, injuries involving the medial talar dome are less likely to be associated with trauma and are less likely to do well with surgical treatment. The diagnosis of cartilage damage (osteochondral lesion, also known as talar dome) is often done with x-rays and/or an MRI. Treatment of Osteochondral Lesions of the Talar Dome Although osteochondral lesions can occur over any portion of the talar dome or the tibia, the talar lesions typically... Medial lesions tend to be deeper and cup shaped. X-rays are taken, and often an MRI or other advanced imaging tests are ordered to further evaluate the lesion and extent of the injury. If the lesion is stable (without loose pieces of cartilage or bone), one or more of the following non-surgical treatment options may be considered: Immobilization. With an MRI, the ligament structures, tendons and cartilage of the ankle can be examined and analyzed. There is no universally accepted treatment algorithm for osteochondral lesions of the talar dome. It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). Swelling is commonly found in acute injuries, although it may be absent in chronic cases especially with medial lesions. Plain radiographs are indicated in the evaluation of any patient with acute or chronic ankle pain. Lesion size, location, chronicity, and characteristics such as displacement and the presence of subchondral cysts help dictate the appropriate treatment … Physical Therapy Management. J Bone Joint Surg Am. Most of the lesions requiring surgical treatment are posteromedial in location, have poor quality articular cartilage, a loose bone fragment, necrotic bone beneath the lesion, and are poor candidates for healing with internal fixation. Typical modalities of activity modification, bracing, nonsteroidal anti-inflammatory drugs (NSAIDs), physical therapy, and protected weight-bearing in a walking boot may alleviate symptoms 26 - 28 . Background: The treatment options of talar osteochondral lesions are numerous. This lack of consensus stems from several factors, including the absence of controlled, randomized studies comparing various treatment alternatives, lack of studies documenting the natural history of untreated lesions of various stages, the addition over time of new diagnostic modalities such as CT and MRI which have expanded our ability to define the lesions preoperatively, and the addition of arthroscopy to the surgeon’s armamentarium. The differential diagnosis of a talar dome lesion includes: Ankle arthritis Ankle fracture High ankle sprain Septic arthritis Sinus tarsitis Talar neck fracture Soft tissue adhesion/defect within the ankle. This can help determine the best treatment approach. (8,9) Differential diagnosis. Surgery may involve removal of the loose bone and cartilage fragments within the joint and establishing an environment for healing. Non-surgical options include: Foot orthotics to provide better alignment of the ankle; A period of immobilization in a walking boot to let the ankle tissue rest and heal lesions and 70% of medial lesions are associated with trauma based on Flick and Gould’s7 review of more than 500 documented talar dome lesions. The top of the talus is dome-shaped and is completely covered with cartilage—a tough, rubbery tissue that enables the ankle to move smoothly.A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. Signs & Symptoms The signs and symptoms of a talar dome lesion may include: Lasting pain deep in the ankle that is worse with activity Clicking or catching feeling in the ankle ... Nonsurgical Treatment Immobilization. Depending on the type of injury, the leg may be placed in a … Depending on the type of injury, the leg may be placed in a cast or cast boot to protect the talus. 68(6):862-5. . 2003;8(2):233-42. Centrally located cysts were not treated by this procedure as … Many terms have been used for OLTs, such as osteochondral defects of the talus, talar dome lesions, osteochondral fracture, transchondral fracture, osteochondritis dissecans, and flake fractures. Osteochondral lesions of the talus (OLTs) are a difficult pathologic entity to treat. Treatment depends on the severity of the talar dome lesion. Verhagen RA, Struijs PA, Bossuyt PM, van Dijk CN. Treatment decisions are based upon the site and size of the lesion, the skeletal maturity of the patient, the quality of the articular cartilage, and the quality of the associated bone fragment. MRI is sensitive in detecting osteochondral lesions of the talar dome and may also aid in the evaluation of other soft tissue and bony entities on the differential diagnosis. Treatment depends on the severity of the talar dome lesion. Such lesions are a tear or fracture in the cartilage covering one of the bones in a joint. Pain with weight bearing and a sensation of giving way are more common but nonspecific complaints. Treatment for these complications is best directed by a foot and ankle surgeon and may include one or more of the following: Nonsteroidal or steroidal anti-inflammatory medications Physical therapy Bracing Surgical intervention In 2007, MRIs of 428 ankles with OLTs were studied. It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). If nonsurgical treatment fails to relieve the symptoms of talar dome lesions, surgery may be necessary. Surgical approaches include simple excision; excision with curettage; and excision, curettage, and drilling. Kouvalchouk et al. 2, 1986 TRANSCHONDRAL TALAR DOME FRACTURES 87 TABLE 1. A variety of surgical techniques is available to accomplish this. 62(4):646-52. . If an osteochondral lesion is noted on plain radiographs, the MRI may be useful in evaluating the lesion itself for articular cartilage congruity, whether there is fluid signal beneath the bony fragment to suggest a loose lesion and to evaluate the degree of edema in the surrounding talus. Sometimes the surgeon will inject the joint with an anesthetic (painrelieving medication) to see if the pain goes away for a while, indicating that the pain is coming from inside the joint. Conservative treatment of osteochondral lesions of the talus (OLTs) should be attempted first, whenever possible. We just can’t do anything to load that part of the cartilage in isolation to confirm the diagnosis. Two studies date from the past (1953 and 1975 ), when surgical treatment of osteochondral talar lesions was not as common as it is today. Smaller diameter cysts would not accommodate the arthroscopic tools. Treatment depends on the severity of the talar dome lesion. J Bone Joint Surg Br. Surgery may involve removal of the loose bone and cartilage fragments within the joint and establishing an environment for healing. A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. To diagnose this injury, the foot and ankle surgeon will question the patient about recent or previous injury and will examine the foot and ankle, moving the ankle joint to help determine if there is pain, clicking, or limitation of motion within that joint. An osteochondral injury to the talar dome produces pain at the ankle and you will find walking and other weight bearing activities difficult. The medial lesions tend to be deeper and cup shaped whereas the lateral lesions tend to be thinner and more wafer shaped (, Most studies have suggested that the lesions are traumatic in nature. Patients tend to present with more chronic symptoms of ankle pain, rather than acute injury. Patients with osteochondral lesions of the talus typically present with non-specific symptoms of vague ankle pain and/or a history of ankle injuries. Cartilage was cut into chips and combined with bone graft product containing platelet-derived growth factor and a porous collagen scaffold. bone graft may be placed if underlying cyst and bone loss. The treatment given for the sprain or injury usually fails to treat the unidentified fracture. Depending on the amount of damage to the cartilage in the ankle joint, arthritis may develop in the joint, resulting in chronic pain, swelling and limited joint motion. Excision of the loose fragment with treatment of the base by curettage, abrasion, or microfracture has been the most commonly recommended treatment for these lesions. If the lesion is stable (without loose pieces of cartilage or bone), one or more of the following non-surgical treatment options may be considered: • Immobilization. There is a slight male predominance in incidence of injury, The staging system proposed by Berndt and Harty (, In the absence of a discrete lesion on plain radiograph, MRI examination is the most appropriate follow-up examination for patients with persistent symptoms despite a period of nonoperative management.
