Background:
The barbed suture technique uses newly developed materials for flexor tendon repair. In this study, the authors examine the effectiveness of using barbed sutures in flexor tendon repair compared with conventional methods.
Methods:
A systematic literature review and meta-analysis was performed using MEDLINE, Embase, and Cochrane databases. Barbed suture and conventional suture methods were extracted as predictor variables, and maximum force, gap formation force, and cross-sectional area were extracted as outcome variables. Subgroup analyses were performed according to the source of suture materials and the number of strands. The Newcastle-Ottawa Scale was used to assess the quality of studies. Publication bias was evaluated using funnel plots.
Results:
The search strategy identified 86 publications. After screening, 12 articles were selected for review. Barbed sutures are comparable in effectiveness to conventional methods in terms of maximum force, gap formation force, and cross-sectional area. In the subgroup analysis, barbed sutures also have comparable effects to conventional methods in terms of maximum force and gap formation force.
Conclusions:
The authors' meta-analysis found that the use of barbed sutures in flexor tendon repair was competitive compared to conventional methods in terms of maximum force and gap formation force. Long-term in vivo studies are needed to confirm these findings.
