Abstract
Purpose: Synthetic augmentation (SA) in anterior cruciate ligament reconstruction (ACLR) aims to enhance graft durability, but its benefits remain unclear. To evaluate whether SA in ACLR improves return-to-sport (RTS) rates, reduces graft failure, enhances patient-reported outcomes (PROs) and varies in effectiveness across materials and techniques.
Methods: A systematic search of five databases was conducted until February 2025. Comparative studies were pooled using Hedges' random-effects meta-analysis with subgroup analysis based on materials and publication year. Non-comparative studies were analysed narratively. Risk of bias was assessed using the Risk of Bias in Non-randomised Studies of Interventions and the Cochrane risk-of-bias tools for randomised studies. Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach was used to assess the certainty of evidence.
Results: Forty-seven studies were included (n = 4289): 7 randomised and 40 non-randomised studies (21 comparative; 19 non-comparative). SA systems included InternalBrace (FiberTape, 16 studies), Ligament Augmentation and Reconstruction System (polyester, 5), Ligament Augmentation Device (polyethylene, 18) and other materials (8). GRADE assessment showed moderate-certainty evidence for improved mid-term RTS rate from eight studies (odds ratio [OR]: 1.58; 95% confidence interval (CI): 1.12-2.22; N = 716; I2 = 0%; p = 0.01). Internal brace showed a reduction in re-rupture rates in the long-term (OR: 0.17, 95% CI: 0.04-0.64; N = 218; I2 = 0%; p = 0.01); however, pooled analysis of all techniques showed no statistically significant difference. Contemporary studies showed a better return to sport rates with SA. PROs showed no clinically meaningful differences. Non-comparative studies showed low graft failure rates (<8.7% for InternalBrace; <16.4% for other SA), high RTS rates (>90% for InternalBrace; >56.7% for other SA) and satisfactory PROs.
Conclusions: SA, particularly InternalBrace, may improve RTS rates and reduce re-rupture risk, though PROs remain inconclusive. Findings are limited by a moderate-to-serious risk of bias, emphasising the need for high-quality research.
期刊介绍:
Few other areas of orthopedic surgery and traumatology have undergone such a dramatic evolution in the last 10 years as knee surgery, arthroscopy and sports traumatology. Ranked among the top 33% of journals in both Orthopedics and Sports Sciences, the goal of this European journal is to publish papers about innovative knee surgery, sports trauma surgery and arthroscopy. Each issue features a series of peer-reviewed articles that deal with diagnosis and management and with basic research. Each issue also contains at least one review article about an important clinical problem. Case presentations or short notes about technical innovations are also accepted for publication.
The articles cover all aspects of knee surgery and all types of sports trauma; in addition, epidemiology, diagnosis, treatment and prevention, and all types of arthroscopy (not only the knee but also the shoulder, elbow, wrist, hip, ankle, etc.) are addressed. Articles on new diagnostic techniques such as MRI and ultrasound and high-quality articles about the biomechanics of joints, muscles and tendons are included. Although this is largely a clinical journal, it is also open to basic research with clinical relevance.
Because the journal is supported by a distinguished European Editorial Board, assisted by an international Advisory Board, you can be assured that the journal maintains the highest standards.
Official Clinical Journal of the European Society of Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA).
