Abstract

Purpose: To compare the clinical outcomes after meniscus allograft transplantation between lateral and medial or isolated and combined procedure groups. Materials and Methods: Of the patients who had undergone arthroscopic meniscal allograft transplantation between Dec. 1997 and Jun. 2007, 52 patients were available for retrospective evaluation. Patients were grouped into lateral(33 cases) and medial(19 cases) transplant groups as well as those with isolated(18 cases) and combined(34 cases) procedure. The average age was 34.2 years and the mean follow-up period was 42.2 months. Postoperative range of motion (ROM), visual analog scale (VAS), International Knee Documentation Committee (IKDC) subjective score, Lysholm score, Tegner score, patient's subjective satisfaction, $2^{nd}$ look arthroscopy and MRI were evaluated retrospectively. Results: Mean postoperative ROM was $130.3^{\circ}$. The VAS showed an improvement from 5.96 to 3.05 at the last follow up. IKDC subjective score and Lysholm score also showed an improvement from 46.5 to 64.5 and from 61.9s to 79.58 respectively. Tegner score was improved from 2.9 to 3.6. Overall, 61.5% of patients reported they were completely or mostly satisfied with procedure. There were no significant differences noted between lateral and medial groups as well as isolated and combined groups. In 2nd look arthroscopy, 10 of 18 cases showed good pheripheal healing and there were 6 cases of partial and 2 of complex tear. We observed graft subluxation or extrusion in 12 of 16 cases who were evaluated with follow-up MRI. Conclusion: Meniscus allograft transplantation alone or in combination with other procedure showed an improvement in knee pain and clinical score. But there were no significant difference between lateral and medial groups or isolated and combined procedure groups.
