Objective To compare clinical outcome of bioabsorbable interference screws (BS) with metal Interference screws (MS) for restruction of anterior cruciate ligament (ACL).
Methods The electronic databases (PubMed, EMbase, Cochrane Central Register of Controlled Trials, CBM, CNKI, and VIP) were searched in order to retrieve randomized controlled trials (RCTs) about comparing BS with MS for restruction of ACL. In addition, reference lists from original studies and review articles were handsearched. The Jadad’s scale and Cochrane collaboration’s RevMan 5.0 software were used for assessing trial methodological quality and data analyses.
Results Eleven RCTs were included. There were 935 participants that met inclusion criteria in all studies. Results of Meta-analyses showed the MS group had a higher Lysholm score. However, no significant differences were found in Lanchman Test, IKDC Data and KT1000 result between patients treated by BS and by MS.
Conclusion Bioabsorbable interference screws provide equivalent clinical outcomescompared with metal interference screws. However, further confirmation is required because of varieties of types and complex compositions.
