Background:
There are no published articles reporting clinical outcomes after all-inside meniscal repair using a suture anchor for a medial meniscal root tear.
Purpose:
To evaluate the subjective and objective outcomes after repair of medial meniscal root tears.
Study Design:
Case series; Level of evidence, 4.
Methods:
Thirteen patients with a root tear of the medial meniscus underwent all-inside repair using a suture anchor. Postoperative evaluation of meniscal status was performed using physical examination criteria, specifically joint line tenderness, McMurray test, and follow-up magnetic resonance imaging (MRI). Functional evaluations were performed using Tegner activity level and Lysholm knee score. Follow-up MRI scans were obtained 6 months postoperatively to evaluate healing of the root tear and measure extrusion of the midbody of the medial meniscus.
Results:
The average follow-up was 30.8 months (range, 24-40 months). No patients had joint line tenderness or effusion. No patients demonstrated a positive McMurray test result postoperatively. The preoperative mean Tegner activity level was 1.9 (range, 1-6), and the mean Lysholm score was 69.1 (range, 53-91). At last follow-up, the mean Tegner activity level was 3.9 (range, 2-6), and the mean Lysholm score was 90.3 (range, 75-100). Improvements in both the Tegner activity level and Lysholm score were statistically significant (P = .001 and P = .000, respectively). Follow-up MRI was performed in 10 patients. Five (50%) patients showed complete healing; 2 of these 5 patients showed complete healing with isointense signal of a normal meniscus, and 3 showed intermediate signal tissue at the previous tear site without any high signal cleft or ghost sign. Four (40%) patients showed partial healing, and 1 (10%) showed no healing. Mean extrusion of the midbody of the medial meniscus was 3.9 mm (range, 2.2-7.1 mm) preoperatively and 3.5 mm (range, 1.2-6.1 mm) postoperatively. Extrusion was not significantly decreased.
Conclusion:
This study demonstrated symptomatic improvement after meniscal root repair using a suture anchor. However, follow-up MRI scans did not show complete healing of all repaired root tears.
