Abstract

Background. Meniscal allograft transplantation (MAT) is an effective reconstructive procedure for treating symptomatic post-meniscectomy syndrome. It consists of replacing the lost meniscal tissue aiming to improve the clinical outcomes and prevent a progressive deterioration of the joint. The aim of this study was to evaluate meniscal graft survivorship and report on the radiographic (in terms of graft extrusion, joint space width and alignment) and the functional results through a mid-term follow-up of lateral MAT performed with a soft tissue fixation technique after capsulodesis.

Methods. 23 patients who underwent lateral MAT as a single procedure were included. The KOOS, Lysholm, Tegner, VAS scales were used for patient assessment. Magnetic resonance imaging and a complete radiographic protocol were conducted to determine the degree of meniscal extrusion and the changes in the degree of osteoarthritis and coronal alignment. Assessments were performed after two and seven years of follow-up.

Results. A significant improvement in all of the scores, relative to preoperative values, was found after seven years of follow-up. This improvement remained consistent throughout the first and second follow-up periods. A mean absolute extrusion of 2.2 mm ± 1.6 and an extrusion percentage of 28.0% ± 11.43 were found, with no significant differences throughout the follow-up periods. There was no statistically significant difference in terms of the frontal mechanical axis and joint space narrowing between the preoperative value and at the first and second follow-up periods. A survival rate of 85.7% was found after seven years of follow-up.

Conclusions. Capsulodesis results in a low degree of meniscal extrusion in lateral MAT fixed with a suture only technique, which is maintained after seven years of follow-up, with a high graft survival index (>85%) and satisfactory results on the functional scales.
