Low-grade lesions are managed with initial weight bearing modifications and therapeutic interventions. About 1 in 5,000 babies are born with some type of skeletal dysplasia. • 2 patients had a recent history of traumatic Impaired function, limited range of motion, stiffness, catching, locking and swelling may … Non operative treatment is commonly the primary choice of intervention in non-displaced OLT such as type I and II lesions above. In summary however, the types of surgery performed include(17): Osteochondral lesions of the talus are a reasonably infrequent cause of long-standing ankle pain and stiffness and are often the result of a severe ankle sprain type injury. Foot Ankle Int. A Study of 5233 Knee Arthroscopies. J Bone Joint Surg Am. Most OLTs occur in either the central middle or lateral middle part of the talus (80%)(8). Osteochondral injury and fractures are most commonly seen with first-time acute patellar dislocation sustained after a traumatic event that produces a large knee effusion. Dr. Wheeless enjoys and performs all types of orthopaedic surgery but is renowned for his expertise in total joint arthroplasty (Hip and Knee replacement) as well as complex joint infections. Talar dome injuries such as osteochondral lesions of the talus (OLT) can occur following an ankle injury, resulting in ongoing residual ankle pain and functional disability. The presence of an osteochondral lesion may initially go undetected and may manifest many months after the initial ankle injury. 1995.

The talar dome is a trapezoid-shaped protuberance of the talus, 2.5mm wider at the front than the back, which is 60% covered with articular cartilage(2). The larger fragments are more likely to … There are two main staging classifications used; one is determined by MRI diagnostic imaging while the other is determined arthroscopically. Grade 0 injury (not shown) is intact cartilage with normal signal and uniform thickness. developed a combined classification system of both MRI and arthroscopy (see table 1)(18)a. (OBQ13.46) A 43-year-old male sustained a left ankle injury 3 years ago. MRI is the most sensitive imaging for OLT with a sensitivity of 96%. Initially, OLT was described and classified as ‘transchondral fractures of the talus’ by Berndt and Harty in 1959(1).

Typically, there is a compressive component to the movement that causes the ankle injury (such as inverting when landing from a jump) in association with a shear-type force, as the talus moves across the tibial plafond or the fibula.                  improve the microscopic appearance of overlying articular cartilage; Osteochondral fractures can also be given the name of articular cartilage injury, although it can also involve fracture of the bone.

Displaced intra-articular osteochondral fragments are usually immediate candidates for surgery. The most widely accepted classification of osteochondral talar injury, introduced by Berndt and Harty [] and based on research on cadavers, is as follows: stage 1 is localized area of subchondral trabecular compression; stage 2 is We strip away the scientific jargon and deliver you easy-to-follow training exercises, nutrition tips, psychological strategies and recovery programmes and exercises in plain English.

Definitions • Osteochondral lesion of talus (OLT): • Only 0.09% of all fractures and 1% of all talus fractures – Traumatic etiology – Commonly: ankle sprain • Inversion injury • 6.5 per 100 ankle sprains – Bosien et al. These findings can be summarized as follows: *Signs and symptoms– Typically, an OLT is not detected in the initial post-injury period unless there has been a large displaced osteochondral fragment. Strengthening of muscles that perform ankle plantarflexion, dorsiflexion, eversion, and inversion. It can reveal an area of low-intensity on T1 imaging (suggestive of sclerosis in the talar bed)(15), while T2 images may show a signal rim of varying intensity between the talar bed and the osteochondral fragment (suggestive of an instability of the osteochondral piece). The classification of OLT depends on the investigation of choice. An initial period of non-weight bearing or partial weight-bearing from three weeks to a month. —Drawings show classification of osteochondral injuries. Fig. In this classification system, stage I is articular cartilage injury only; stage II is cartilage injury with bony fracture and is further broken down into acute or chronic based on the presence or lack of edema; stage III consists of a).              bone and therefore shearing injuries most often produce a chondral injury rather than an Typical signs and symptoms of OLT are(13): However, based on imaging studies compared with the above complaints, an OLT can be present without the physical signs mentioned above(14). A randomized trial. An osteochondral ankle defect is a lesion of the talar cartilage and subchondral bone mostly caused by a single or multiple traumatic events, leading to partial or complete detachment of the fragment. It is this process that is postulated to lead to the long-term degenerative sequelae sometimes seen in the knees or ankles of patients with previous osteochondral injury []. An experimental study in dogs.  The talar dome has no direct muscle attachments(2); during normal ankle motion of ankle dorsiflexion and plantarflexion, the talar dome (trochlear) rotates and slides against the undersurface of the tibia. However, a CT scan is unable to see early lesions present only in the cartilage(16). The majority of classification studies have compared MRI with arthroscopic findings to allow the clinician to classify the severity of the OLT based on MRI findings (see classification below).

Sports Injury Bulletin brings together a worldwide panel of experts – including physiotherapists, doctors, researchers and sports scientists. fracture, dislocation, sprain or strain).   Osteochondral defect is a broad term that describes the morphological change of a localised gap in the articular cartilage and subchondral bone 5. ICD-10-CM Code for Osteochondral fracture of patella S82.01 ICD-10 code S82.01 for Osteochondral fracture of patella is a medical classification as listed by WHO under the range - Injury, poisoning and certain other consequences of external causes .           - references: It is often used synonymously with osteochondral injury/defect and in the paediatric population. The talar dome is a trapezoid-shaped protuberance of the talus, 2.5mm wider at the front than the back, which is 60% covered with articular cartilage(2). The cartilage on the talus has less inherent stiffness than the corresponding sites on the tibia (18-37% stiffer on the tibia); therefore it is more vulnerable to harm from shear and compression than the tibia(4). An incongruent talar position due to an unstable ankle means that the lateral talus may experience excessive forces causing damage to the cartilage in that area(3). Foot Ankle Clinics North America. These are as follows(16): The typical framework for conservative treatment is as follows(16): Logically speaking, a patient with an acute ankle sprain that may have an OLT of significance will most likely be in a degree of pain and discomfort.
