Recently, the interest on anatomical ACL reconstruction with double bundle technique is increased to reproduce the original load distribution, and kinematics of the knee. We developed an arthroscopic double bundle ACL reconstruction technique using autogenous quadriceps tendon with 2 splitted graft and patellar bone plug. The anteromedial bundle and posteolateral bundle of the ACL is replicated with each splitted graft of quadriceps tendon and fixed with biodegradable interference screw on the 2 femoral tunnels. The patellar bone plug of quadriceps tendon is fixed with biodegradable interference screw within the 1 tibial tunnel. We suggest that our technique using quadriceps tendon may be an alternative in arthroscopic double bundle ACL reconstruction.

In order to obtain a good result in Arthroscopic ACL Reconstruction by immediate postoperative physical therapy, sufficient analgesia was needed. This study analyzes the analgesic effect of the intra-articular injection with ketorolac, Morphine together with bupivacaine in 80 male patients who had Arthroscopic ACL Reconstruction. On completion of the surgery under spinal anesthesia, the knee was injected with 30ml of 0.25% bupivacaine. Each of the study group received ketorolac and/or morphine, either through parenteral or intra-articular. Total amount of the drug used by Patient Controlled Analgesia(PCA) and Visual Analgesia Scale(VAS) for pain were measured and analyzed. The group which received intra-articular ketorolac or Morphine had a better analgesic effect than other group which received none. The group which received both did not do better in analgesic effect. Intra-articular infusion with either ketorolac or Morphine improved postoperative analgesia in Arthroscopic ACL Reconstruction surgery. However, combined injection did not offer more advantage.

Between March 1992 and December 1995 at St. Paul's, Holy Family, St. Vincent and Eui Jung Bu St. Mary Hospitals Catholic University, two hundred and eighty patients underwent arthroscopic anterior cruciate ligament(ACL) reconstruction using central one-third bone-patellar tendon-bone autograft. Nine of these patients had limitation of motion(LOM) defined as a knee flexion contracture greater than 10o or less than 125o of passive knee flexion. This study analyzes the causes of LOM after ACL reconstruction as well as the results after passive manipulation or arthroscopic adhesiolysis under anesthesia for LOM. The results are as follows: 1. Out of nine patients, initially three had isolated ACL injuries and six had combined injuries. Seven of nine cases were perfomed by ACL reconstruction within four weeks and two were performed after four weeks following injury. 2. Treatment for LOM after ACL reconstruction was done after 5.5 months on average. 3. Arthroscopic adhesiolysis was done in 5 cases. There were fibrous adhesions at suprapatellar pouch and femoral intercondylar notch in all cases, respectively, infrapatellar fat pad in 3 cases and medial para patellar gutter in 2 cases. Two patients had a fibrous nodule, "cyclops" lesion, which formed anterior to the ACL graft. 4. Range of motion and Lysholm knee score were much improved following passive manipulation or arthroscopic adhesiolysis under anesthesia for LOM.

Purpose: To evaluate the knee joint after double-bundle anterior cruciate ligament (ACL) reconstruction with three-dimensional (3D) isotropic magnetic resonance (MR) image, and to directly compare the ACL graft findings on 3D MR with the clinical results. Materials and Methods: From January 2009 to December 2014, we retrospectively reviewed MRIs of 39 patients who had reconstructed ACL with double bundle technique. The subjects were examined using 3D isotropic proton-density sequence and routine two-dimensional (2D) sequence on 3.0T scanner. The MR images were qualitatively evaluated for the intraarticular curvature, graft tear, bony impingement, intraosseous tunnel cyst, and synovitis of anteromedial and posterolateral bundles (AMB, PLB). In addition anterior tibial translation, PCL angle, PCL ratio were quantitatively measured. KT arthrometric values were reviewed for anterior tibial translation as positive or negative. The second look arthroscopy results including tear and laxity were reviewed. Results: Significant correlations were found between an AMB tear on 3D-isotropic proton density MR images and arthroscopic proven AMB tear or laxity (P < 0.05). Also, a significant correlation was observed between increased PCL ratio on 3D isotropic MRI and the arthroscopic findings such as tear, laxities of grafts (P < 0.05). KT arthrometric results were found to be significantly correlated with AMB tears (P < 0.05) and tibial tunnel cysts (P < 0.05). Conclusion: An AMB tear on 3D-isotropic MRI was correlated with arthroscopic results qualitatively and quantitatively. 3D isotropic MRI findings can aid the evaluation of ACL grafts after double bundle reconstruction.

From Feb. 1996 to Feb. 1997. among sixty-four patients of anterior cruciate ligament(ACL) reconstruction using multi-stranded hamstring tendon and EndoButton fixation, twenty-five patients of volunteer, 15 men and 10 women, from 16 to 50 years of age(mean 27.6 years) underwent arthroscopic evaluation. Arthroscopic evaluation was routinely performed one year after surgery along with an examination of stability. The purpose of this study was to arthroscopically evaluate the morphological changes that occurred in hamstring tendon autograft one year after ACL reconstruction. Both of the tendon graft and the adjacent fibrous tissues were observed for gross appearance and physical properties with probing and response to passive anterior translation. Biopsy samples were taken from the surrounding fibrous tissue and the tendon graft. Grossly, we found a well-defined ligamentous structure with good tension tested with a probe. A common finding was that the reconstructed ligaments were embedded in a layer of the synovium, and blood vessels could be seen on the anterior surface of the ligament. The biopsy tissue was placed in formalin solution and subjected to histological preparation by hematoxylin and eosin staining method. The hamstring tendon graft appeared histologically normal under light microscopic finding. There were a few vessels located between existing collagen bundles, and the vessels had an orderly pattern. The surrounding fibrous tissue envelope was covered with synovium. We pleased with preliminary findings in our evaluation.

The arthroscopic ACL reconstruction using the bone-patellar tendon-bone has been considered as the gold standard in the treatment of the ACL insufficiency. There are many reports about the good functional outcome and the restored stability of the knee joint. But there are a few reports showing whether this surgery has good results in the patients' satisfaction. The purpose of this study is to evaluate the patients' satisfaction in this surgery. Authors analysed 32 cases who had taken the ACL reconstruction from Jannuary, 1989 to June, 1997. The average follow-up was 40 months. At the last follow-up, 32 patients reported the patients' satisfaction degrees(four degrees; very satisfied, generally satisfied, improved, no change or aggravated), KT-1000 arthrometer test, Vastus atrophy(thigh circumference), and three kinds of the knee scores(Lysholm, HSS, IKDC). Among the 32 cases, 12 cases (37.5%) were very satisfied, 17 cases(53.1%) were generally satisfied and 3 cases(9.4%) were improved. No case showed no change or aggravated. The satisfaction degree in this surgery had little relation with the age, operation time, follow-up period, combination of meniscectomy, but had significant relations with anteroposterior stability evaluated by KT-1000, thigh circumference measurements and the functional scoring of the knee(Lysholm, HSS, IKDC scores).

대퇴 터널 속에 횡고정 나사로 네가닥의 자가 슬괵건을 고정하는 전방십자인대 재건술은 이식된 건과 골이 만나는 부위에서 건-골 융합 과정(골통합, osteo-integration)이 필요하다. 본 증례는 외상성 전방십자인대 파열 환자에서 자가 슬괵건을 이용한 전방십자인대 재건술후 13주째에 수술한 전방십자인대 실질부(substance)의 외상성 재파열이 생겨 이를 관절경적 재수술을 시행하는 과정에서 대퇴 터널 내 골-이식건 결합부를 채취하여 조직학적 관찰을 시행하였다. 조직학적 소견은 이식건과 골 사이에 콜라젠 섬유의 연속성이 존재하는 이식건의 골통합 소견을 관찰할 수 있었다. 본 증례의 조직학적 소견과 전방십자인대 재건술후 초기에 이식건 파열의 낮은 발생율은 수술후 대퇴 터널에서의 자가 이식건-골의 융합이 수술후 12주에서 15주 사이에 완성된다는 주장을 뒷받침할 수 있을 것으로 사료된다.
