Purpose: The purpose of this study was to evaluate the clinical results and the changes of allogenic meniscal transplantation by using the second look arthroscopic findings and the MRI changes after surgery.
Materials and Methods : From July 1997 to February 2007, among the patients that underwent allogenic meniscal transplantation, we chose 25 patients who underwent secondary arthroscopic evaluation. 16 of these 25 patients were men and 8 were women. Secondary arthroscopic evaluation was done without MRI in 3 cases. The mean age was 36.1 yr and the average follow up period was 28 months. Biopsy by the secondary arthroscopic evaluation was done in 2 cases. We evaluated the clinical results by the Lysholm knee scoring scale, the Knee Society Score (KSS) system and the Hospital for Special Surgery (HSS) knee score.
Results: Second-look arthroscopy after allogenic meniscal transplantation revealed that 23 cases seemed normal at the probing procedure. 5 cases showed a decreased posterior horn size. The MRI findings and secondary arthroscopic findings matched in all cases. The clinical Lysholm score improved from preoperative 65.4 points to postoperative 80.6 points, the Knee Society Score (KSS) improved from preoperative 64.6 points to postoperative 82.6 points, the functional score improved from preoperative 70.2 points to postoperative 85.6 points and the Hospital for Special Surgery (HSS) knee score improved from preoperative 66.4 points to postoperative 82.5 points (p=0.000). The function after surgery improved on all the tests and this was proved by paired t-tests.
Conclusion: Allogenic meniscal transplantation showed good results on the second look arthroscopy and the follow-up MRI and according to the clinical functional outcome. We think that confirmation through arthroscopy after follow-up MRI for the patients with clinical knee problems seems to be necessary.
