Large lesions are treated by the OATS procedure. Your doctor treats OCL by removing the damaged tissue followed by microfracture, which enables natural healing of the damaged bone and cartilage. The structures inside the ankle are visible to your surgeon on a monitor in the operating room. ArthroscopyĪn arthroscope is a narrow tube with a tiny video camera on one end. Small lesions can be treated non-surgically involving the use of a cast, physical therapy, pain medications, strengthening exercises, etc. Treatment of OCL of the Talus (Ankle) Non-surgical Method MRI is the best imaging modality, which helps to visualize the cartilage and bone lesions as well as bone edema. A CT scan helps identify any bony fragments but is not very helpful to visualize bone edema or cartilage defects. Plain X-ray images can reveal other fractures, bone spurs, and narrowing of the joint. Osteochondral lesions are diagnosed by a physical examination, X-ray, and CT and MRI scans. Large lesions are associated with symptoms such as localized ankle pain and discomfort which worsens while walking or running, a clicking or popping sound, swelling, tenderness, weakness of the foot, etc. OCL may be genetic or may be caused due to trauma, stress fractures in sports, severe sprain, local osteonecrosis, etc. The division surgeons were pioneers in using concentrated bone marrow aspirate in OCL of the ankle and continues to be at the forefront of stem cell therpy, autologous osteochondral transplant (OATS) and other cartilage sparing techniques. The division has more experience in this condition than any other facility in the US with over 100 publications reporting on outcomes. Osteochondral (OCL) injuries of the ankle (Talus and Tibia) as well as other joints including the 1st MTP, subtalar and navicular are common. Usually, the inner or the medial portion of the ankle is affected. OCL or OCD is the damage to the cartilage and the talus bone of the ankle joint. The talus bone is an important bone located between the tibia and fibula and the heel bone (calcaneus). The tibia and the fibula bones of the lower leg join with the talus bone to form the ankle joint. Osteochondral Lesions of the Talus (Ankle)
