Purpose: To report the treatment results of arthroscopic osteochondroplasty in osteochondral lesion of the talus.
Materials and Methods: This study included 32 patients who had osteochondral lesion of the talus treated with arthroscopic osteochondroplasty and were able to be followed up over 3 years from 1999 to 2007. The mean follow up period was 48 (38-108) months, and 22 male patients and 10 female patients with a mean age of 34 (20-56) years were included. Locations of lesion were evaluated with simple X-ray and magnetic resonance imaging (MRI), and severities of lesions were classified by Berndt and Harty classification. All cases were treated by arthroscopic debridement or microfracture. The treatment results were assessed by American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale and subjective and functional score of Kailkkonen. The group treated by arthroscopic microfracture was compared with the group treated by arthroscopic debridement.
Results: The mean AOFAS ankle-hindfoot scale was significantly improved 53 (±7) points preoperatively to 84 (±8) points postoperatively (P<0.001). The mean subjective and functional score was also improved 55 (±8) points preoperatively to 88 (±8) points postoperatively with statistical significant (P<0.001). There were no relations between the severity of lesions and the postoperative functional score of ankle (P>0.05). There were no significant differences in the clinical results between the group treated with arthroscopic microfracture and the group treated with arthroscopic debridement (P>0.05).
Conclusion: Arthroscopic osteochondroplasty of osteochondral lesion of the talus shows excellent result in terms of patients’ satisfaction. There were no significant differences in the clinical results between arthroscopic microfracture group and debridement group.
