Abstract
Purpose
To evaluate the treatment outcomes of transmalleolar multiple drilling with a K-wire for an osteochondral lesion of the medial talar dome after an mean follow-up period of 77 months.
Materials and Methods
Among patients treated surgically for a symptomatic osteochondral lesion of the talus between March 1997 and December 2002, sixteen ankles (fifteen patients) with a medial talar dome lesion were treated by transmalleolar multiple drilling and followed-up for at least 3 years. The average age at the time of surgery was 34.4 years (range, 19-58 years). The mean follow-up period was 77 months (range, 41-107 months).
Results
At the latest follow-up, the average VAS at motion decreased from 6.8 to 2.1 (p=0.004). The AOFAS score improved from 64 points to 86.2 points (p=0.001). The 8 ankles in those less than thirty years of age at that time of surgery showed a VAS at motion of 1.8 and an AOFAS score of 91.1 points. In contrast, 8 ankles in those who older than thirty one years of age had a VAS at motion of 2.4 and an AOFAS score of 81.2 points. The younger group showed a significantly better AOFAS score than the older group (p=0.001). However, there was no significant difference in the VAS score (p=0.22).
