23.1.4 - Outcomes and Survival Rate of Collagen Matrix-Based Meniscus Repair: 4- to 8-year Follow-up Study
Abstract
Purpose
To report the MRI and clinical outcomes with survival rate at a minimum 5-year follow-up in a series of patients with complex meniscal tear and treated with a collagen matrix-based meniscus repair.
Methods and Materials
Fifty-four consecutive patients operated on from 2010 to 2011 with the mean follow up 5,92- year (3,56-8,34) were included. We lost to follow up 6 patients so to final analysis was included 48 cases. Functional scores (IKDC, Lysholm) were assessed preoperatively, 2-year, and at the last follow-up. EQ 5D 5L score were assessed at the last follow-up. The state of the meniscus and the total WORMS OA score was also evaluated in MRI.
Results
Forty-eight patients were included to the final analysis. Four meniscus were partly resected to the last follow up - 8,3% failure rate. The functionality of the knees improved from preoperative to 2 –year follow up and were even better at 5-year follow up in all the scores used (P < .001). Thirty-seven patients were examined by MRI 2 and 5 years postoperatively. MRI revealed a non-homogeneous signal without meniscal tear in 2-year follow up in 92% and in 5-year follow up in 81% of the operated menisci. The total WORMS score increased from main 6,89 in 2-year follow up to main 11,1 in 5-year follow up. No progression to the OA level was observed. Sex, age and BMI have no correlation with 2- and 5-year outcomes. The time from injury to the surgery correlated with clinical outcome. The EQ-5D-5L was 0,943.
Conclusion
The 2- and 5-year follow-up data demonstrate this technique is safe with acceptable failure rate and can offer an additional tool to save the meniscus in the patients otherwise scheduled for meniscal removal. The quality of life 5 year after surgery is very good. The procedure protects the knee against the progression of degenerative.
