To prospectively evaluate the mosaicplasty technique for treatment of femoral condylecartilage lesions (Outerbridge grade IV) less than 2.5 cm2 in homogeneous group of young activepatients. Type of Study: Case series. Methods: Thirty-seven patients (10 female, 27 male; mean age,29.5 years) with full-thickness knee chondral lesions were treated by the arthroscopic mosaicplastytechnique. All patients practiced sports. There were 12 ACL reconstructions, 11 medial meniscectomies,and 8 lateral meniscectomies associated; 10 meniscectomies, 9 ACL reconstructions, and 5cartilage reparative operations had been previously performed. All patients were evaluated at a 2-yearfollow-up. The International Cartilage Repair Society (ICRS) form, return to sports, computedtomography, or magnetic resonance imaging were used for clinical evaluation. In some cases,second-look arthroscopy was performed. Results: The ICRS showed 78.3% good and excellentresults; 27 patients returned to sports at the same level and 5 at a lower level, but 5 were not able toresume sports. Results in the lateral condyles were significantly better than those in medial condyles,and younger patients had a better clinical outcome than did older patients. Cases with associatedsurgery had better clinical results; previous surgery did not significantly influence the clinicaloutcome. Conclusions: The results of this technique at medium-term follow-up are encouraging with78.3% clinically satisfactory results. Better results can be obtained in young patients with associatedsurgery, with localized grade 4 lesions of the lateral condyles. This arthroscopic 1-step surgeryappears to be a valid solution for the treatment of grade III-IV cartilage defects not more than 2.5 cm2.Level of Evidence: Level IV, Case Series.
