Background: It is known that meniscus root tears affect the biomechanics of the knee in a

way that is equivalent to a total meniscectomy. Therefore, repair is increasingly favored

for meniscal root tears. In our study, we aimed to investigate the clinical and radiological

outcomes of meniscal root repairs with suture anchors. Materials and Methods: Patients

who had undergone surgery for medial meniscus posterior root tear (MMPRT) using

suture-anchors between 2018 and 2023 were retrospectively analyzed. Patients were ex-

cluded if they had a previous infection, a fracture and an operation on the same knee,

or osteoarthritis and a follow-up period under one year. The MMPRTs were classified

according to the LaPrade classification system. For the functional classification, the range

of motion (ROM), the Visual Analog Scale (VAS), the Lysholm Knee Score (LKS), and the

International Knee Documentation Committee (IKDC) Subjective Knee Form were used

for the postoperative functional assessments. The radiological assessment was performed

by measuring the medial meniscus extrusion (MME) and evaluating the signal changes

in the magnetic resonance imaging (MRI) of the knee, which was recorded during the last

follow-up examination. Results: Thirty-two patients (6M/26F) were included in the study.

The mean age was 49.9 ± 5.4 years old, and the follow-up period was 29.6 ± 24.1 months.

The LKS improved from 53.7 ± 6.9 to 83.6 ± 5.2 and the IKDC improved from 46.1 ± 6.9 to

83.0 ± 5.5 at the final follow-up control (p < 0.001 and p < 0.001). The VAS score de-

creased from 8.4 ± 0.5 to 2.5 ± 0.9 (p < 0.001). The MRI scan of the knee performed at

the last follow-up examination showed no improvement in only one patient. While the

MME before surgery was 5.0 ± 2.1 mm, it was 4.6 ± 2.1 mm at the last follow-up ex-

amination (p = 0.178). An increase in the Kellgren–Lawrence stage was observed in 4 of

our patients (from stage 1 to stage 2 in one patient, from stage 0 to stage 1 in 3 patients).

Conclusions: The results of this study suggest that repairing MMPRTs using suture-anchors

is a valid solution for treatment and prevention in patients with poor prognoses in order to

achieve positive results in reducing pain, restoring mobility, improving functional outcomes

and avoiding a significant increase in progression to arthrosis.
