Abstract
OBJECTIVE: To investigate the effectiveness of arthroscopic reinforced reconstruction of anterior cruciate ligament (ACL) with autologous hamstring tendon combined with anchor suture band. METHODS: Between February 2016 and March 2018, 60 patients who were to be treated with arthroscopic ACL reconstruction and met the selection criteria were selected in the study. Among them, 30 cases were reconstructed with autologous hamstring tendon combined with anchor suture band (trial group), and 30 cases were reconstructed with simple autologous hamstring tendon (control group). There was no significant difference in gender, age, disease duration, cause of injury, injury side, and preoperative Lysholm score, Tegner score, and International Knee Documentation Committee (IKDC) score between the two groups ( P>0.05). After reconstruction, the patients in the trial group were allowed to start knee flexion and extension activities early without wearing an adjustable brace, while the patients in the control group were required to wear an adjustable brace for 12 weeks. The knee joint function (Lysholm score, Tegner score, IKDC score) and stability (Lachman test and pivot shift test) were compared between the two groups after operation. RESULTS: There was no significant difference in graft diameter between the two groups ( t=1.061, P=0.115). Compared with the control group, the operation time of the trial group was significantly different ( t=4.924, P=0.000). All incisions healed primarily. In the control group, the intramuscular venous thrombosis occurred in 2 cases after operation. Both groups were followed up 18 months. The Lysholm score, Tegner score, and IKDC score of the two groups at each time point after operation were significantly higher than those before operation ( P<0.05); the above scores in the trial group were significantly higher than those in the control group at 3, 6, and 9 months after operation ( P<0.05); there was no significant difference between the two groups at 18 months after operation ( P>0.05). There was no significant difference in Lachman test results between the two groups at each time point after operation ( P>0.05). There was a significant difference in pivot shift test results at 6 months after operation between the two groups ( P<0.05); but there was no significant difference at other time points ( P>0.05). CONCLUSION: The effectiveness of ACL reinforcedreconstruction with autologous hamstring tendon combined with anchor suture band is satisfactory. Compared with using autologous hamstring tendon alone, it has better initial strength and joint stability, and is more conducive to early postoperative functional exercise and functional recovery of knee joint.
