[] Although majority may be associated with trauma, some may develop insidiously. A patient with an osteochondral lesion will often feel a dull ache in the joint and may also experience a mild locking or clicking of their knee or ankle joint. During this period of immobilization, nonweightbearing range-of-motion exercises may be recommended. Scranton PE and McDermott JE. this is sutured … For adults, such a condition usually requires surgery. Treatment options include: non-operative conservative therapy (including but not limited to modification of activity, injections, casting, or boots), various surgeries like “microfracturing” the affected bone which brings new cells to the area in hopes building new cartilage, or transplantation of cartilage/bone from a donor or different body part. An OLT is an injury to the cartilage and underlying bone of the talus within the joint, where it begins to soften and break off as a result of not healing properly. Osteochondritis dissecans (OCD) is a condition that develops in joints, most often in children and adolescents. One would use a non-invasive ankle distractor to distract the joint and check the lesion. Use a cast to allow for healing of the lesion for six to eight weeks. One would perform an arthroscopy of the joint and identify the lesion. An osteochondral defect refers to a focal area of damage that involves both the cartilage and a piece of underlying bone. Non-surgical: Osteochondral lesions of the ankle can be treated with injections of Platelet-rich plasma and hyaluronic acid, which results in a decrease in pain scores and an increase in function for at least 6 months. Osteochondritis dissecans (OCD or OD) is a joint disorder primarily of the subchondral bone in which cracks form in the articular cartilage and the underlying subchondral bone. A medial lesion was reproduced by plantarflexing the ankle in combination with slight anterior displacement of the talus on the tibia, inversion, and internal rotation of the talus on the tibia. Scranton PE, Jr., Frey CC, Feder KS. Microfractures, are often considered the first-line surgical treatment option due to the low costs and ease of the technique (34-38), while ACI is rather reserved as a salvage procedure (39-41, 45). This is referred to as an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). We try to avoid drilling of these lesions as the superficial cartilage and bone are intact and stable. 109. Choose a doctor and schedule an appointment. Then you fill the region with either allograft or autograft. It is important to understand the principles of arthroscopy and the use of a microvector guide in the treatment of osteochondral lesions. Osteochondral lesions of the talus (OLTs) are a difficult pathologic entity to treat. Outcome of osteochondral autograft transplantation for type-V cystic osteochondral lesions … For most kids and young teens with osteochondritis dissecans, the … Foot and Ankle International, May 2001; 22(5): 380-384. “Osteo” means bone and “chondral” refers to cartilage.

There is a great deal of debate as to whether you should use autograft, fresh allograft or graft substitutes. Lesion size, location, chronicity, and characteristics such as displacement and the presence of subchondral cysts help dictate the appropriate treatment … Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. Arthroscopic treatment of the OLTs aims to restore ankle joint function and pain relief by the removal of the chondral or osteochondral fragment, debridement and stabilization of cartilage rim and subchondral bone, and stimulate healing of the bone and damaged cartilage. For stable lesions, non-operative management is usually the first step including: A Stable lesion means that the cartilage overlying the bone is not damaged and the lesion is not likely to be lose. bone graft may be placed if underlying cyst and bone loss. Treatment is split up into three grades, depending on how severe the injury is: Grade 1: This treatment doesn’t require any invasive procedures. Seven studies described the results of non-operative treatment, 4 of excision, 13 of excision and curettage, 18 of excision, curettage and bone marrow stimulation (BMS), 4 of an autogenous bone graft, 2 of transmalleolar drilling (TMD), 9 of osteochondral transplantation (OATS), 4 of autologous chondrocyte … There is a great deal of debate as to which adjunct testing is best for diagnosing an osteochondral lesion. Treatment depends on the severity of the talar dome lesion. Operative treatment might also be necessary if patients do not respond well to conservative treatment. Actual surgical treatments for osteochondral lesions and early knee osteoarthritis seem to be promising.

Cartilage is a connective tissue that covers the bones between joints. Surgical treatment of talar OLTs includes: Arthroscopic … The treatment for Osteochondral Defect depends on the size of the defect and whether the overlying cartilage is damaged. Although the treatment of osteochondral lesions of the talus has evolved and improved, there is a need to understand the full spectrum of treatments and be well-versed in all forms of treatment in order to have a complete bag of tools necessary to treat these complicated occurrences. Treatment and prognosis. Finally, there is a subchondral cyst type injury with a cyst formation deep to the cartilage surface but an intact overlying cartilage and bone surface. ➢ Operative treatment should be reserved for patients who have mechanical symptoms following an acute osteochondral lesion of the talus or who are not satisfied with the result after 3 to 6 … FIGURE 71-1 Osteochondral lesion of the talus. Often, performing an injection of local anesthetic into the involved joint will reduce pain but clinicians should not rule out other problems such as loose bodies, synovitis and ligament injury. Initial x-rays are taken to check the alignment of the foot and ankle, as well as look for any bone damage. Once the diagnosis has been confirmed, treatment may be surgical or non-surgical, depending on the nature of the OLT, presence of other injuries and patient characteristics. One can use two allograft regions that mimic the normal makeup of talar cartilage. The goal of non-surgical treatment is to allow the injured cartilage and bone to heal. One may use radiographs to check for a cyst formation or cartilage damage but this imaging rarely shows definitive involvement. With an MRI, the ligament structures, tendons and cartilage of the ankle can be examined and analyzed. Osteochondral lesions of the talus occur for several reasons. Although the cause of such lesions is unknown, they may involve a genetic predisposition to such a condition. Know what is Osteochondral defect, its causes, symptoms, treatment and prevention. For older patients, a knee replacement may be an option. There are three types of common lesion formation. Osteochondritis dissecans (OCD) is a condition that develops in joints, most often in children and adolescents. There is also a problem with mild sclerosis of the walls of the cyst that one must treat. Our preferred technique is to use a 0.62 K-wire and drill lesions in the posterior medial region that cannot be reached with a chondral pic through a medial incision approach. He is an Associate Professor at UCLA Medical Center and is the Chief of Podiatric Surgery at Santa Monica/UCLA Medical Center. Usually, an osteochondral lesion occurs when there is an injury to the joint, especially if there is an ankle sprain or if the knee is badly twisted. Then using a microvector guide, the surgeon would drill a tunnel from the sinus tarsi region into the cystic lesion with a guide pin. The vast majority of patients experience no pain or swelling even 10 years after surgical treatment of such lesions in the ankle. It occurs when a small segment of bone begins to crack and separate from its surrounding region due to a lack of blood supply. Medial lesions … I hope the information presented is helpful for your patient care. It can be challenging to diagnose an osteochondral lesion at the time of injury. The newest and most complicated treatment option is the use of retrograde drilling of the lesion. With an MRI, the ligament structures, tendons and cartilage of the ankle can be examined and analyzed. Treatment depends upon the size of the osteochondral defect and the condition of the overlying cartilage. Osteochondral injury staging system for MRI attempts to grade the stability and severity of osteochondral injury and is used to plan management.. stage I. injury limited to articular cartilage; … How To Diagnose And Treat Osteochondral Lesions Of The Talus, How To Assess And Treat Ligamentous Laxity Syndromes In The Foot And Ankle, Pertinent Pearls In Evaluating And Treating Chronic Ankle Instability, Current Best Practices In The Treatment Of Plantar Plate Tears. This may be followed with gradual progression of weightbearing and physical therapy. Outcome of osteochondral autograft transplantation for type-V cystic osteochondral lesions of the talus. Younger patients, particularly … An osteochondral defect can occur acutely or develop as a result of several chronic conditions including (a) separation of the osteochondral fragment caused by an acute traumatic injury or as the end result of an unstable fragment in osteochondritis dissecans (OCD), (b) acute osteochondral … The second most common type is an injury to the superficial cartilage surface with a crush cartilage injury or shear tear of the cartilage surface. Operative Treatment . Diagnosing an osteochondral lesion is very difficult on a physical exam and one rarely diagnoses this without further testing. This type of injury is fairly rare. INTRODUCTION. Conservative treatment of osteochondral lesions of the talus (OLTs) should be attempted first, whenever possible. Operative Treatment . Scranton PE, Jr., Frey CC, Feder KS. 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. Treatments for lesions in the knee are more challenging, but also have promising outcomes. debridement of lesion to create stable cartilage rim, subchondral bone exposed. Scranton PE and McDermott JE. Treat subchondral edema either through a retrograde approach from the sinus tarsi or from an intraarticular approach through the lesion site via subchondroplasty with or without a bone marrow aspirate add-on. A chondral defect refers to a focal area of damage to the articular cartilage (the cartilage that lines the end of the bones). Over the next few years, one may be able to begin treating cartilage lesions with cartilage cell transplants through an injection and with cartilage caps. In general, our guideline for a cutoff for drilling options is a lesion less than 1 cm in diameter and a lesion less than 0.5 cm in depth. Osteochondral Defect is the name given to a condition most noticeable in the knee, in which a part of the bone and cartilage gets separated from the knee joint. After the initial pain and discomfort of a strain or sprain subsides, individuals usually resume or even increase their activity level. If the damage is small, the surgeon may drill into the bone, which causes a small amount of bleeding and encourages healing. Surgical options differ according to the size, depth … A chondral defect refers to a focal area of damage to the articular cartilage (the cartilage that lines the end of the bones). The most common cause is from a crush or injury to the surface of the bone during the abnormal motion of the ankle in a sprain. As the size of the lesion and, more importantly, the depth of the lesion increase, drilling and removal of the lesion show less than perfect outcomes. Treatment of the subchondral bone will aid in pain relief even if one treats the overlying cartilage. If the patient presents such kind of changes, the most recommended form of intervention is represented by the complete replacement of the joint. the lateral osteochondral defect. The goal of treatment is to ease pain and get your child back to using their joint normally. 1.

At earlier stages (stage 1 to 4), a number of options … It occurs when a small segment of bone begins to crack and separate from its … After surgery, weight should be kept off the affected knee or ankle for four to six weeks. 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 . A talar osteochondral lesion (OLT) can develop after ankle sprains or ankle trauma. In cases of osteochondral lesion, the patient will begin to experience swelling and pain in the ankle with this increased activity.
