Objective To investigate the feasibility and effectiveness of a novel remnant-preserving anterior cruciate ligament (ACL) reconstruction with bidirectional barbed suture.Methods Between February 2014 and January 2016, 96 patients (96 knees) with ACL injury who met the inclusion criteria were recruited and randomly divided into 2 groups (n=48). All patients underwent ACL reconstruction with autologous tendon. The tibial remnant was fixed with PDS-Ⅱ suture (control group) and bidirectional barbed suture (trial group). There was no significant difference in age, gender, injury side, the interval from injury to operation, and preoperative knee stability (KT-1000 test), International Knee Documentation Committee (IKDC) score, and Lysholm score (P>0.05). The knee stability (KT-1000 test), IKDC score, Lysholm score, proprioception, and Cyclops lesion after operation were recorded.Results All incisions healed by first intention in both groups. Forty-four patients in control group were followed up 26-47 months (mean, 36.6 months), and 45 patients in trial group were followed up 26-48 months (mean, 35.6 months). At last follow-up, the IKDC score, Lysholm score, and KT-1000 test were significantly improved when compared with preoperative ones in both groups (P<0.05); but no significant difference was found between 2 groups (P>0.05). There was no significant difference in proprioception between 2 groups at 1 and 2 years after operation, and between 1 year after operation and 2 years after operation (P>0.05) in the same group. The incidences of Cyclops lesion at 6 months, 1 year and 2 years after operation were 0, 4.44% (2/45), and 4.44% (2/45) in trial group, and 13.6% (6/44), 13.6% (6/44), 20.5% (9/44) in control group, showing significant differences between 2 groups at 6 months and at 2 years after operation (P=0.012; P=0.022) and no significant difference at 1 year after operation (P=0.157).Conclusion The remnant-preserving ACL reconstruction with bidirectional barbed suture can decrease the incidence of Cyclops lesions. However, this technique can not improve the effectiveness in terms of the clinical function and stability compared with the traditional technique.
