Mosaicplasty in the treatment of the losses of focal cartilaginous substances: Anatomical results of a series of 10 cases

Abstract

The focal cartilaginous losses of the knee or the ankle in young patients raise essentially a therapeutic problem. The surgery is indicated to the unstable painful hurts in carrying arthrogenous zones. The mosaicplasty is a therapeutic option. Estimate the results of this medium-term technique. Our forward-looking series contains 10 cases interesting eight men and two women, middle-aged 32.5 years. Gene functional estimated by the score International Cartilage Repair Society (ICRS) was important in every case. The locations interested the knee in eight cases and the ankle in two cases (astragalien dome). The hurts were quite in carrying zone (zone 2: four cases, zone 4 and 5: three cases) according to the classification of Cahill and Berg and had an average area of 2.04 cm2. Associated lesions were present in seven cases. The mosaicplasty was performed on average 29 months after the onset of clinical symptoms. The grafts used were 8 or 10 mm in diameter (1–4). The overall coverage is 78% (65–90%). The results were evaluated with a mean of 40 months. We have satisfactory functional results in 90% of cases and 80% of satisfactory anatomically results (control arthro-CT or MRI). Our study and literature review confirms the efficacy and low morbidity of the technique of mosaicplasty in the treatment of cartilage defect from 1 to 3 cm2.
