Abstract
Osteochondral lesions of the talus present with symptoms of pain and painful motion,
affecting the quality of the patient’s daily life. We evaluated the 2-year short-term
outcomes of patients whose large osteochondral lesions of the talus were treated with
medial malleolar osteotomy and a mosaic graft harvested from the knee on the same
side. A total of 32 patients who had cartilage lesions due to osteochondritis dissecans
in the medial aspect of the talus underwent mosaicplasty after medial malleolar osteotomy.
The patients were followed up for a mean period of 16.8 (range 12 to 24) months. The
staging and treatment plan of the osteochondral lesions of the talus were made according
to the Bristol classification. The follow-up protocol for the patients included direct
radiography and magnetic resonance imaging. The American Orthopaedic Foot and Ankle
Society scoring system was used to assess the patients during the pre- and postoperative
periods. Of the 32 patients, 3 (9.4%) were female and 29 (90.6%) male, with a mean
age of 27.5 (range 20 to 47) years. The mean preoperative American Orthopaedic Foot
and Ankle Society score was 59.12 ± 7.72 but had increased to 87.94 ± 3.55 during
the postoperative 2 years. The increase in American Orthopaedic Foot and Ankle Society
score was statistically significant (p < .05). We have concluded that open mosaicplasty is a reliable and effective method
for the treatment of osteochondral lesions with subchondral cyst formation in the
talus, exceeding 1.5 cm in diameter.
