Clinical and Radiological Short-Term Results after Meniscal Allograft / 대한정형외과학회잡지

ABSTRACT

PURPOSE: The purpose of this study was to evaluate the clinical and radiological results after meniscal allograft transplantation (MAT). MATERIALS AND METHODS: From October, 2010 to August, 2013, 45 patients, 47 cases who underwent MAT were reviewed. The mean age was 39.9 years and the mean follow-up period was 24.9 months. The clinical results were evaluated using Lysholm score and International Knee Documentation Committee (IKDC) score. All cases were evaluated by serial postoperative radiograph. And 18 cases were performed postoperative magnetic resonance imaging (MRI). Eighteen cases including the 13 cases that had graft dislocation or subluxation and signal changes in MRI underwent second-look arthroscopy. RESULTS: Lysholm score was elevated from mean 58.4 at preoperative to 92.4 at last follow-up. IKDC score was elevated from mean 50.3 at preoperative to 90.1 at last follow-up. Among the 18 cases who underwent postoperative MRI, subluxation was found in 10 cases (55.6%) and graft dislocation with grade III signal change was found in 3 cases (16.7%). However, the 13 cases showed a well healed state of the graft capsule in second-look arthroscopy. There was no joint space narrowing on radiograph during the follow-up period. CONCLUSION: After MAT, 93.6% of cases showed improved the clinical results above good. Thus, it is effective in relatively young and active patients with meniscus functional deficit and minor meniscal degeneration.
