Inside-Out or Outside-In Suturing Should Not Be Considered the Standard Repair Method for Radial Tears of the Midbody of the Lateral Meniscus: A Systematic Review and Meta-Analysis of Biomechanical Studies.

Journal Article (Review)

The purpose was to evaluate which meniscal repair technique for radial tears of the midbody of the lateral meniscus demonstrates the best biomechanical properties. An electronic literature search was conducted using PubMed, EMBASE, CINAHL, and ScienceDirect databases. Biomechanical studies investigating the repair characteristics of radial tears in the midbody of the lateral meniscus were included. After appropriate screening, a total of 54 studies were reviewed in detail (full text), and 6 met inclusion criteria. The most common cause of exclusion was the investigation of longitudinal tears. Only two studies could be meta-analyzed. Stiffness was significantly higher for all-inside compared with inside-out repair techniques (p = 0.0009). No significant differences were observed between both suture methods for load to failure (p = 0.45). However, both studies used different all-inside devices and suture constructs. No clear conclusions can be drawn from the comparison of both types of repairs for displacement, site of failure, or contact pressure changes. Overall, there are no conclusive data to suggest that inside-out or outside-in suture repair has better load to failure or stiffness, less displacement, or different site of failure compared with all-inside repair. According to biomechanical data, it is under surgeon's preference to elect one repair technique over the other.
