O3197 A LONG TERM FOLLOW-UP OF OSTEOCHONDRAL LESION OF TALUS CLINICAL RESULTS BY ARTHROSCOPIC DRILLING



Abstract

Aims: Arthroscopic drilling for the treatment of osteo-chondral lesion (OCL) of talus has been able to return earlier to social life resulting from less invasive operation. However, long term results of drilling have not been clear. Results of arthroscopic drilling for OCL which have passed 5 years or longer are reported. Methods: Subjects were 54 feet in 52 patients who had passed more than 5 years who underwent arthroscopic drilling. Age ranged 21 to 52 years with an average of 34 years. Classiþcation based on Berndt & Harty was as follows: 1 foot for stage?, 38 feet for stage?, 8 feet for stage?and 7 feet for stage?. Resdults: No patients showed limited range of motion at the þnal examination. With pain, 2 patients developed pain in the lesion, while no patients showed disturbance in gait, either. With sports, all the patients returned to initial sports, however, in patients with extensive lesion (3 patients), there remained pain causing a decrease in sports level. X-ray þndings revealed osteoarthritic change in three patients. Conclusions: In the present study, in patients of 90 percent or greater, there were no new developed or deterorated pains. However, osteoarthritic change was observed in the cases with lateral ligaments tear or subchondral bone cyst. Thus, it may suggest the limit in the indications of drilling. Furthermore, since there remained pain in the patients with complicated injuries or extensive lesion, it may be difþcult to obtain excellent results with use of arthroscopic drilling alone.
