One step treatment of talus osteochondral lesions with microfracture and cell free hyaluronic acid based scaffold combination.

Abstract

The aim of this study was to assess the effectiveness of microfracture and cell free hyaluronic acid (HA) based scaffold combination in the treatment of talus osteochondral defects (OCD). This study retrospectively evaluated the clinical results of the 20 patients (14 males and 6 females, mean age at the time of surgery: 32.9 years (range: 16-52 years)) who were treated with MFx and cell-free HA-based scaffold combination for talus OCD smaller than 1.5 cm² and deeper than 7 mm. Results were evaluated with AOFAS and VAS scores. Also, patients' satisfaction was questioned. Patients were evaluated after an average follow-up of 20.3 months. Intraoperative measurements showed that mean depth of the lesions were 10.4 ± 1.9 mm after debridement. The mean preoperative AOFAS score was 57.45 ± 9.37, which increased to 92.45 ± 8.4 postoperatively (p < 0.05). VAS score was improved from 7.05 ± 2.45 to 1.65 ± 2.20 postoperatively (p < 0.05). MFx and cell-free HA-based scaffold combination appear to be a safe and efficient technique that provide good clinical outcomes for lesions deeper than 7 mm. Level IV, Therapeutic Study.
