  • Numerous techniques of anterior cruciate ligament (ACL) reconstruction have been described in literature. All have inherent advantages and disadvantages. The central one-third patellar tendon and hamstring tendons are the most commonly used autogenous tissues for replacement of a torn anterior cruciate ligament. Although the central one-third patellar tendon is considered to be 'the gold standard' for replacement of torn ACL. equivalent results have been reported using hamstring tendon grafts. Autogenous hamstring grafts provide adequate strength while avoiding donor site morbidity associated with bone-tendon-bone harvest. $EndoButton^{\circledR}$ femoral fixation allows precise femoral tunnel placement without a second incison. The purpose of this article is to describe surgical techniques using a quadrupled semitendinosus tendon and $EndoButton^{\circledR}$ fixation, and review the results of replacement of ACL.

  • This article describes a modified arthroscopic technique of anterior cruciate ligament (ACL) reconstruction using quadrupled hamstring tendon graft. The autogenous semitendinosus and gracilis grafts are harvested without detachment of the tibial insertion. To obtain longer graft, the accessory tibial insertions of the hamstring tendons are dissected. The EndoButton(Acupex Microsurgical, Andover, MA) is used for femoral fixation and two spiked staples are used for tibial fixation in a belt buckle fashion. Then the residual anterior laxity is restored by additional absorbable interference screw fixations. In this technique. more viable graft is obtained and firmer distal fixation is achieved by preservation of the tibial insertion of hamstring tendons.

  • This study is retrospective analysis of 31 patients treated by arthroscopically assisted ACL reconstruction, from September 1995 to September 1996. ACL reconstructions using autogenous bone patellar tendon bone (B-PT-B) were done in 18 patients, and using hamstring tendon were done in 13 patients. We used four-stranded hamstring tendon grafts and fixed the grafts using Endobutton and screw. The mean postoperative Lysholm knee score was 87.2 points in B-PT-B. group, and 89.0 points in hamstring tendon group. There were no clinically significant results between two groups in Telos test, quadriceps atrophy, Lachman test, anterior drawer test and pivot shift test, but the incidences of anterior knee pain were lower in hamstring group. Four-stranded hamstring tendon graft showed enough stability and good functional outcome similar to that of patellar tendon graft, and had an advantage of quicker return of quadriceps function and less donor site morbidity.

  • Purpose: Double-bundle reconstruction of anterior cruciate ligament(ACL) has the advantage of restoring the isometry and original function of ACL. The purpose of this study is to evaluate the clinical results following double-bundle reconstruction of ACL using autogenous hamstring grafts through an accessory anteromedial portal. Materials and Methods: From January 2005 to July 2006, sixty patients(52 males, 8 females) underwent double-bundle ACL reconstruction using autogenous hamstring tendons..The mean age was 31.7 years($20{\sim}51$ years). The mean follow up period was 13.4 months($12{\sim}16$ months). We made a horizontal-oblique skin incision just medial to tibial tuberosity and harvested semitendinosus and gracilis tendon. Tibial tunnel for posterolateral bundle was made near its anatomical position. By modifying an anatomic reconstruction of ACL by Yasuda et al., we made a femoral tunnel for posterolateral bundle through accessory anteromedial portal. Tunnels for anteromedial bundle were made with conventional method. We reconstructed anteromedial bundle with semitendinosus tendon and posterolateral bundle with gracilis tendon. Clinical results at last follow up were evaluated by range of motion, extent of anterior displacement(KT-1000 arthrometer), pivot-shift test. Functional evaluation of clinical outcomes were evaluated by Lysholm score and modified Feagin Scoring System. Results: There was no limitation of motion of knee joint at last follow up. Mean side to side difference of anterior displacement of tibia by KT-1000 arthrometer was improved from 8.4 mm preoperatively to 1.7 mm postoperatively(p<0.05). Average Lysholm score was improved from 64.1 preoperatively to 92.2 postoperatively(p<0.05). In modified Feagin Scoring System, 90% of cases were rated as good or excellent. Conclusion: Double-bundle reconstruction of ACL using autogenous hamstring grafts through accessory anteromedial portal results in good clinical outcomes.

  • Purpose: We describe a new technique of arthroscopic repair with using autogenous hamstring tendon graft augmentation for the acute posterior cruciate ligament rupture. Operative technique: A routine arthroscopic examination of the knee joint is initially performed, then the posterior trans-septal portal is prepared with the using the posteromedial and posterolateral portals. The torn tibial stump that is retracted to the posterior compartment is repaired by a suture hook that is introduced through the anteromedial portal; visualization during this procedure is done with the arthroscope via the posteromedial portal. Using the retrieved suture, both suture ends are brought out to the anteromedial portal. The torn tibial stump is pulled to the intercondylar notch and then repaired with stitches at the anterior compartment. After the tibial and femoral tunnels are prepared without damaging the remnant PCL bundle, the combined torn PCL fibers and the autogenous single-bundle semitendinosus and gracilis tendon grafts are passed through the femoral tunnel and fixed together Conclusion: Arthroscopic repair of the torn tibial stump and autogenous hamstring tendon graft augmentation after preparing the tibial and femoral tunnels by using the trans-septal portal, without damaging the remnant PCL bundle, seems to be a very effective method for the treatment for acute PCL injuries, and especially for tears at the femoral attachment.

  • Purpose: To compare the stability and clinical result after anterior cruciate ligament reconstructed knee after graft fixation using Intrafix in tibial tunnel with or without additional tibial post fixation. Materials and Methods: We analyzed 37 cases which were treated with four-strand hamstring tendon autograft during the period from May 2002 to January 2003. The grafts were fixed with Rigidfix system (Mitek Product, Johnson and Johnson, USA) in femur tunnel and Intrafix system (Mitek Product, Johnson and Johnson, USA) in tibial tunnel. After tibial fixation, additional tibial post fixation was done, which was determined by the serial case number prospectively. Patients were followed for average of fourteen months(range, thirteen to twenty-five months) At the time of final follow-up, patients were evaluated in terms of Lachman test, pivot shift test, Lysholm scores, IKDC (International Knee Documentation Committee) assessment, side-to-side KT-1000 maximum-manual arthrometer differences. Results: At last follow-up, Lysholm score was average 93.1(range: 65 to 98), IKDC assessment revealed that 26 cases had score of A, 10 cases had score of B and 1 case had score of C. The average maximum-manual KT-1000 arthrometer side ?to-side difference was 2.5 mm$(0{\sim}6mm)$. There was one case in which the Lachman test was graded as 2+ and four cases in which the Lachman test was graded as 1+ and the remaining thirty-two cases were normal by Lachman test. One case had a 2+ pivot-shift, and 2 cases had a 11 pivot-shift. The remaining 34 knees were normal on pivot -shift testing. The average maximum-manual KT-1000 arthrometer side-to-side difference was average 2.8 mm$(0{\sim}6mm)$ in Intrafix only group and average 2.2 mm$(0{\sim}4mm)$ in additional fixation group (P>0.05). Conclusion: Without additional tibial fixation, the stability of the anterior cruciate reconstructed knee with hamstring graft which was fixed with Intrafix was restored.
