AbstractA retrospective study of 22 ankles in 22 patients with osteochondral talar dome lesions between 1975 and 1983 has indicated that surgical treatment yields superior results to conservative therapy. Thirteen male and 9 female patients, ages 9 to 72 years, average age 28 years, showed 10 medical lesions (Berndt and Harty classification (stage I (one); stage II/III (nine)) and 12 lateral lesions (stage II/III (5), stage IV (7)). Examination follow-up on 19 patients (86%) has averaged 24 months. The initial diagnosis seen retrospectively on x-rays was missed 43% of the time by emergency room physicians. A history of trauma was verified in 100% of the lateral lesions and 80% of the medial talar dome lesions. Of the 22 ankles, 14 lesions were isolated injuries, while 8 had concomitant fractures, lateral ligament, or peroneal tendon damage. Surgical treatment consisted of removal of the osteochondral fragment, curettage, and drilling of its bed. Two distinct surgical approaches were utilized. Lateral dome lesions were approached through the standard anterolateral incision, while medial dome lesions were approached through the anterior tibial tendon sheath with grooving of the anteromedial distal tibia articular surface. The medial approach allowed the somewhat posteriorly placed medial lesions to be reached, negating the need for a medial malleolar osteotomy and postoperative immobilization. On follow-up, no untoward ankle arthrosis was noted as a result of the grooving of the anteromedial distal tibia. Nineteen of the 22 patients had surgical therapy with 79% excellent or good, 21% fair, and no poor results. Five of the eight patients who elected prolonged conservative therapy finally had surgery. Of the three remaining patients conservatively treated, there were two fair results and one poor result.
