The purpose of this prospective Study is to report the outcome of arthroscopic repair of radial lateral menicus tears at the junction of the anterior horn and body. Five patients with an average age of 27 years were treated. The repair was performed with double horizontal Sutures by inside-out technique, using zone-specific, curved cannulae with no enhancement technique. A mean of 2.4 Superior and 2.8 inferior stitches were performed. Reduction was obtained in all cases. Patients were evaluated using Lysholm functional knee scores. All patients were clinically and radiologically examined using MRI to assess meniscus integrity at the repair site, over an average follow-up period of 3 1 months. All patients were able to return to their former level of activity. In all cases, MRI showed a fully healed meniscus at the repair sites, with no further disruption of the debrided area. The mean Lysholm scores improved from 62 preoperatively to 94 postoperatively. The difference between preoperative and postoperative values was found to be statistically significant (p=0.029). No cases of postoperative extra or intra-articular complications were encountered. We found that repairing rather than resecting radial lateral menicus tears I I I that extend into capsular zone, improves activity level. (C) 2008 Elsevier B.V All rights reserved.
