Summary

Between January 2010 and December 2014, 31 consecutive cases of OLT with a subchondral cyst smaller than 8 mm in diameter received arthroscopic debridement. The clinical and radiological results were studied. The results of arthroscopic debridement for OLT with subchondral cysts are satisfactory, and the cysts disappeared or decreased postoperatively.

Abstract

Objective

To analyze the clinical and radiological results of arthroscopic treatment for Heppleā€™s type V osteochondral lesion of talus(OLT) with small cysts. Method Between January 2010 and December 2014, 31 consecutive cases of OLT with a subchondral cyst smaller than 8 mm in diameter received arthroscopic debridement. The visual analog scale score for pain during daily activities, American Orthopaedic Foot & Ankle Society hindfoot and ankle score were obtained. Magnetic resonance imaging of the ankle were studied before and after surgery, and the diameter of the cysts were measured on MRI image. Result Thirty patients were followed up for an average of 20.1 months. The average post-operative visual analog scale score was 1.3±5.1, compared with 4.9±2.2 before operation. The average post-operative ankle-hindfoot score of AOFAS was 90.5±8.4, compared with 73.7±9.3 before operation. 23 patients got postoperative MRI examination, the subchondral cysts disappeared in 8 cases, and the average diameter of the cysts decreased from 5.54mm to 2.26mm postoperatively. Conclusion. The results of arthroscopic debridement for OLT with subchondral cysts are satisfactory, and the cysts disappeared or decreased postoperatively.
