Operative Treatment of Osteochondral Lesion of the Talus: Arthroscopic Bone Marrow Stimulation (Multiple Drilling or Microfracture) / 대한족부족관절학회지

ABSTRACT

Osteochondral lesion of the talus (OLT) is a broad term used to describe an injury or abnormality of the talar articular cartilage and adjacent bone. Various terms are used to describe this clinical entity, including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. Several treatment options are available; the choice of treatment is based on the type and size of the defect and the treating clinician’s preference. Arthroscopic microfracture (a bone marrow stimulation technique) is a common and effective surgical strategy in patients with small lesions or in those in whom non-operative treatment has failed. This study had the following aims: 1) to review the historical background, etiology, and classification systems of OLT; 2) to describe a systematic approach to arthroscopic bone marrow stimulation for OLT; and 3) to determine the characteristics that are useful for assessing osteochondral lesions, including age, size, type (chondral, subchondral, cystic), stability, displacement, location, and containment of the lesion.
