Objective To investigate the effectiveness of portable bracket of lower limb in the reconstruction of anterior cruciate l igament (ACL) by the long fibular muscle tendon under arthroscopy. Methods Between March 2008 and September 2010, 22 patients with ACL injury were treated. The limb position was maintained by portable bracket of lower limb and ACL was reconstructed with the long fibular muscle tendon under arthroscopy. There were 15 males and 7 females with an average age of 33.8 years (range, 19-64 years). The causes of ACL injury were traffic accident injury in 14 cases, sport trauma in 5 cases, and fall ing injury in 3 cases. The locations were the left knee in 10 cases and the right knee in12 cases, including 12 fresh injuries and 10 old injuries. Of 22 patients, 17 had positive anterior drawer test, 19 had positive pivot shift test, and 20 had positive Lachman test. According to International Knee Documentation Committee (IKDC) criteria, there were 6 abnormal and 16 severely abnormal. The subjective IKDC score was 57.64 ± 6.11. The Lysholm score was 55.45 ± 4.37. Results All incisions healed by first intention, and no complication was found. All patients were followed up 9-38 months (mean, 15 months). At last follow-up, the flexion of the knee ranged from 120 to 135° (mean, 127°). One patient had positive anterior drawer test, 1 patient had positive pivot shift test, and 2 patients had positive Lachman test. No ligament loosening and breakage occurred. According to the IKDC criteria, 10 patients rated as normal, 11 patients as nearly normal, and 1 patient as abnormal. The subjective IKDC score was 90.44 ± 6.11, showing significant difference when compared with preoperative one (t=4.653, P=0.021). The Lysholm score was 90.12 ± 5.78, showing significant difference when compared with preoperative one (t=4.231, P=0.028). Conclusion Portable bracket of lower limb in the reconstruction of ACL has the advantages of saving manpower and easy operation. The long fibular muscle tendon is enough long and b to reconstruct the ACL, which can increase the contact surface between the tendon and bone and is beneficial to tendon-bone heal ing.
ObjectiveTo compare the effectiveness of anterior cruciate ligament (ACL) reconstruction between by long fibular muscle tendon and by hamstring tendon under arthroscopy after ACL rupture. MethodsBetween February 2010 and December 2012, 56 cases of ACL rupture underwent ACL reconstruction under arthroscopy. The long fibular muscle tendon was used in 26 cases (group A) and the hamstring tendon was used in 30 cases (group B). There was no significant difference in gender, age, side, disease duration, and preoperative Lachman test, Lysholm score, and the International Knee Documentation Committee (IKDC) score between 2 groups (P>0.05). The treatment after operation was identical in 2 groups. ResultsPrimary healing of incision was obtained after operation in 2 groups. There was no major neurovascular injury and knee synovitis. There was no significant difference in operation time, hospitalization time, and postoperative 24-hour drainage volume between 2 groups (P>0.05). The patients were followed up 25-32 months (mean, 28 months) in group A, and 27-37 months (mean, 31 months) in group B. There was no related complication at donor site in 2 groups. MRI examination showed good ACL reconstruction. The Lysholm score and the IKDC score of group A at 6 months after operation were significantly better than those of group B (P<0.05), but no significant difference was found between 2 groups at 2 years after operation (P>0.05). There was no significant difference in Lachman score between 2 groups at 6 months and 2 years after operation (P>0.05). ConclusionThe long fibular muscle tendon for arthroscopic reconstruction of ACL has much simpler operation, earlier knee function recovery, and better subjective satisfaction than the hamstring tendon.
