ARTHROSCOPIC SINGLE-BUNDLE ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION USING SIX-STRAND AUTOGRAFT HAMSTRING TENDON PLUS TightRope SUSPENSION PLATE

Abstract

To explore the effectiveness of arthroscopic single-bundle anterior cruciate ligament (ACL) reconstruction using six-strand autograft hamstring tendon plus TightRope suspension plate. Between September 2014 and August 2015, 24 patients with ACL rupture accepted arthroscopic single-bundle ACL reconstruction using six-strand autograft hamstring tendon plus TightRope suspension plate. There were 16 males and 8 females with an age range of 18-54 years (mean, 36.2 years). The disease causes included sport injury in 15 cases, traffic accident injury in 4 cases, and sprain in 5 cases. The mean time from injury to operation was 3.9 months (range, 18 days to 8 months). The results of anterior drawer test, pivot shift test, and Lachman test were positive before operation. The preoperative International Knee Documentation Committee (IKDC) score was 38.69±3.85 and Lysholm knee functional score was 36.45±7.85. The incisions healed by first intention. No infection, deep vein thrombosis, or vessel and nerve injuries occurred. MRI showed the good tunnel position and ACL morphology. All patients were followed up 6-16?months with an average of 12 months. At last follow-up, Lysholm and IKDC scores were significantly increased to 81.31±7.58 and 79.62±5.39 respectively (P < 0.05). The results of anterior drawer test were negative in 17 cases and positive degree I in 7 cases; the results of Lachman test were negative in 20 cases and positive degree I in 4?cases; the results of pivot shift test were negative in 21 cases and positive degree I in 3 cases; and all showed significant differences compared with preoperative results (P < 0.05). Arthroscopic single-bundle reconstrustion using six-strand autograft hamstring tendon plus TightRope suspension plate is a simple technique for ACL reconstruction, which can obtain satisfactory short-term effectiveness.
