Mosaicoplasty for the treatment of osteochondral injuries of the knee: Evaluation of 62 patients with 8 years of average follow-up

There are several surgical options described for osteochondral defects of the knee. The aim of our study was to analyze a series of patients treated with mosaicplasty with an average of 8 years follow-up. Sixty-two patients with osteochondral defects of the knee who underwent mosaicplasties between 2001 and 2014 were included in the study with minimum follow-up of 2 years. Patients were evaluated using the Lysholm score, International Knee Documentation Committee Score (IKDC) and Kellgren-Lawrence radiographic scale. Forty-five were men and seventeen women with an average age of 36 years old. Mosaicplasties were 45 in the medial condyle, 12 lateral condyle, 12 trochlea and 3 combined. Forty-two patients had isolated mosaicplasties and 20 patients presented associated surgical procedures (osteotomy, ACL reconstruction, meniscectomy). The mean results of the Lysholm score were 80.1 and IKDC was 66.7. There were no significant differences among the Lysholm and IKDC scores between these two groups. In 30 patients evaluated with radiography a satisfactory inclusion of the bony block was observed. We believe that mosaicplasty is a procedure with a high degree of satisfaction with good functional results in patients with focal lesions of articular cartilage that may or may not be associated to other surgical procedures
