Objective: This study aimed to evaluate the clinical and radiological results of patients with medial femoral condyl defect who were treated with microfracture technique added with BST-CarGel® or Hyalofast as a scaffold at the end of surgery.

Methods: A total of 12 patients who had undergone microfracture surgery added with BST-CarGel® or Hyalofast as a scaffold were evaluated. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score was clinically evaluated, and the area measurement and depth and underlying structures (AMADEUS) score and defect filling were radiologically evaluated.

Results: The mean patient age was 49.66±6.31 years, and the mean follow-up time was 21.75±7.72 months. Seven patients also received BST-CarGel®, and five received Hyalofast at the end of surgery. The improvement of the WOMAC score, AMADEUS score, and defect filling after treatment were significant compared with preoperative data (p<0.001). No difference was found clinically and radiologically between the
BST-CarGel® or Hyalofast group.

Conclusion: Microfracture treatment supplemented with BST-CarGel® or Hyalofast scaffolds at the end of surgery is a safe and helpful treatment for cartilage defects.
