Medial Meniscus Scaffold Implantation in Combination with Concentrated Bone Marrow Aspirate Injection: Minimum 3-Year Follow-up

The objective of this study is to show the short-term clinical and radiological outcomes of concentrated bone marrow aspirate (CBMA) injection administered in combination with medial meniscus scaffold implantation. Twenty-three patients who received intra-articular CBMA injection in combination with polyurethane-based medial meniscus scaffold implantation were evaluated within the scope of this study. The International Knee Documentation Committee (IKDC) questionnaire and the Knee injury and Osteoarthritis Outcome Score (KOOS) were used to evaluate the results, and the visual analog scale was used to assess the pain scores. Magnetic resonance imaging (MRI) scans were obtained in the preoperative period and at postoperative months 1, 12, 24, and 36 to assess the scaffold position as well as chondral degeneration/damage in a comparative manner. MRI assessment was performed by using the modified Outerbridge scale for cartilage and the Genovese scoring system for the meniscal implant. Twenty-three patients who were included in the study were evaluated for a mean follow-up period of 38.3 months. Patients exhibited statistically significant improvement according to all scoring data from the preoperative period until the follow-up period. The mean postoperative extrusion at year 3 was 2.39 mm (distribution 2.30–2.56 mm). There was no significant difference in the distribution of the degree of chondral damage between the preoperative and 3-year follow-up periods. Four patients ...
