Clinical effects of arthroscopic microfracture on osteochondral lesions of the talus / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical effects of arthroscopic microfracture on osteochondral lesions of the talus.</p><p><b>METHODS</b>Total 42 patients with osteochondral lesions of the talus, who were collected in our department from January 2011 to December 2013. The patients were 35.9 years old on average, including 28 males and 14 females. There were 34 patients who had injury histories. The debridement and microfracture were performed under arthroscopy. The function of ankle was assessed according to AOFAS Ankle Hindfoot Scale. MRI of ankle was checked 2 years postoperatively.</p><p><b>RESULTS</b>There were 23 cases in stage 3, 9 cases in stage 4 and 10 cases in stage 5 in MRI. There were 25 cases on the 4th district, 11 cases on the 6th district, 4 cases on the 1st district, 2 cases on the 3rd district according to 9 districts location and 8 cases of subchondral cyst found on the 4th district. AOFAS Ankle Hindfoot Scale of all patients on the 1st year postoperatively was 73.3±3.9 which was significantly better than 50.4±7.8 preoperatively, and 81.1±4.8 on the 2nd year postoperatively was also significantly better than that on the 1st year postoperatively.</p><p><b>CONCLUSIONS</b>Arthroscopic microfracture for the osteochondral lesions of the talus could have a good clinical effect.</p>
