Abstract:
Objective To evaluate the mid-term results of arthroscopic anterior cruciate ligament (ACL) reconstruction using Transfix technique.Methods From August 2002 to December 2003,38 patients (24 left knees and 14 right knees) with ACL ruptures underwent arthroscopic ACL reconstruction with hamstring tendon using Transfix femoral fixation and interference screws tibial fixation.There were 21 males and 17 females,aged from 19 to 48 years (average,28.4 years).The causes of injury included sports injury in 27 cases,traffic injury in 2 cases and fall injury in 2 cases,and 7 patients had no significant injury.There were 6 cases of acute injury and 32 cases of old injury.Anterior drawer test was positive in 35 cases,weak positive in 1 case and negative in 2 cases.Lachman test was positive in 37 cases,and weak positive in 1 case.The Lysholm score was used to evaluate the results.Moreover,X-rays and MRIs were used to observe the conditions of graft and bone tunnel.Results Thirty-six patients were followed up for 6.3 to 7.6 years (average,6.8 years).All patients had normal joint range of motion.The Lysholm score improved from preoperative 64.4±4.52 to postoperative 85.6±4.60,and the difference was statistically significant (P ＜ 0.05).The X-rays and MRIs showed femoral and tibial tunnel enlargement in 3 cases,femoral tunnel enlargement in 5 cases and tibial tunnel enlargement in 3 cases.No joint space narrowing was found in all patients.One patient underwent arthroscopic revision ACL reconstruction with allograft tendon using bioabsorbable interference screws fixation on both tibial and femoral sides for re-rupture of ACL 4 years after operation due to trauma.Conclusion Arthroscopic ACL reconstruction with hamstring tendon using Transfix femoral fixation and interference screws tibial fixation is an effective method,which can provide satisfactory joint range of motion and stability.
