The prevalence of anterior cruciate ligament (ACL) injury is continuously increased due to sports activities and traffic accident. Simultaneously ACL reconstruction operations are on the increase. Several kinds of autografts and allografts are used in ACL reconstruction. Although ACL reconstruction using an autogenous bone-patellar tendon-bone graft is the good standard, it might have potential morbidity, anterior knee pain and minimal extension loss. To minimize the complications and disadvantages on each graft and to select appropriate graft for each patient, it is necessary to understand the unique characteristics of each graft for biomechanical aspect, morbidity and disadvantage. Selecting the appropriate graft depends on numerous factors including surgeon's preference and experience, patient's activity level and age, extent of ligament injury, tissue availability, and patient's selection for graft .

While the cruciate ligament has a profuse vascular response following injury, spontaneous repair does not occur. This may result from the fact that synovial fluid dilution of the hematoma following injury prevents the formation of a fibrin clot and thus the initiation of the healing mechanism. Another theory suggests that the dynamic nature of the fascicles of the anterior cruciate ligament(ACL) through even small ranges of motion prohibits spontaneous union to these fibers. But we experienced two cases of spontaneous healing of partially injured ACL. Initially they showed more than grade II anterior instability. 6 mm difference by stress roentgenographs(pull view) and difference of 8 mm by KT 1000TM arthrometer between the ACL injured knee and normal side knee. Lax, nearly complete tear of ACL and synovial bleeding were noted during arthroscopic examination but the continuity of synovial membrane was seemed to be intact. These cases were treated by conservative management rather than reconstructive procedure. Postoperatively they showed excellent clinical results, no anterior instability and unlimited athletic activity. Based on our clinical experience. we think that cruciate ligament has the spontaneous healing potential in acute stage and middle aged patient. We consider the microfracture technique and initial immobilization for accelleration of healing response of the ACL.

Purpose: To report the results of graft retention treatment for infection cases after anterior cruciate ligament(ACL) reconstruction. Materials and Methods: From a group of 511 consecutive ACL reconstruction patients, we report 5 who sustained septic arthritis. All patients underwent arthroscopic lavage, debridement, synovectomy with graft retention, and treatment with intravenous antibiotics. Results: All patients were evaluated at an average of 34 months after operation. The infection was successfully eradicated. No patient showed instability with KT-2000 arthrometer testing. The clinical outcome was inferior to normal ACL reconstruction patients. Two patients were graded as nearly normal and 3 patients were graded as abnormal with International Knee Documentation Committee evaluation form. Conclusion: There were no recurrences of septic arthritis or bone infection with graft retention treatment for infection patients after ACL reconstruction.

A 34-year-old man with ACL total rupture due to slip down injury, had received ACL reconstruction using autogenous hamstrings tendon with cross-pin femoral fixation. Postoperative course was as usual. But postoperative 3 months later, he complained posterolateral knee pain, recurrent effusion and mild instability. He was managed repeatitive aspiration and nonsteroid antiinflammatory drugs but was failed to relieve symptoms & signs. In CT scans, perforation of posteromedial femoral cortex of lateral femoral condyle was found. In second look arthroscopy, two pieces of broken femoral cross pin were found in between tibiofemoral Joint which was badly injured cartilage. We considered malposition of pins was the main cause of failure. We propose that femoral tunnel must be made more acute angle and femoral cross-pin guide must be positioned more external rotation 10-20 degree than transepicondylar axis made confirm the cross-pin tunnel position in order to avoid posterior cortex perforation and early failure.

Purpose: To evaluate the clinical results of the patients who underwent radiofrequency thermal shrinkage (RFTS) for treatment of anterior cruciate ligament (ACL) laxity after ACL reconstruction. Material and Methods: From October 1999 to March 2006, we performed 133 cases of ACL reconstruction. Among them we experienced 16 patients who had the laxity of reconstructed ACL in second look arthroscopy. Mean follow-up was 20.4 months. Mean age was 33.5 years. 12 cases were male and 4 cases were female. The elongated ACL were treated by bipolar radiofrequency energy with an output of grade II. Subjective and objective parameters were utilized in analyses, such as: the mean range of motion, Lysholm knee score, Tegner activity score, Lachman test, IKDC score. Wilcoxon signed-rank test was used to perform the data analysis. P<0.05 was considered to be statistically significant. Results: Postoperative mean Lysholm knee score (preop: $82.2{\pm}5.2(77{\sim}85))$ (P=0.04), postop: $85.2{\pm}4.8$(82-90)) and anterior displacement by the Telos stress test (preop: $5.4{\pm}4.6(3{\sim}10)mm$, postop: $2.1{\pm}1.9(0{\sim}4)mm)$ (P=0.02), Lachman's test, and IKDC scores (P=0.04) demonstrated significant differences statistically compared to the preoperative. There were no statistical differences in mean range of motion, Tegner activity scale. Conclusions: Arthroscopic shrinkage for the ACL laxity after ACL reconstruction with radiofrequency device showed good clinical results and was applicable operative technique.

전방십자인대 재건술시 자가건 선택에 대해서는 많은 논쟁의 소지가 존재하며 많은 보고들이 나오고 있으나, 현 시점에서 이식건으로써 자가 골-슬개건-골이 표준(gold standard)라는 주장은 이제 변화하고 있으며, 골-건 고정방법의 개선에 따른 조기 슬관절 안정성의 호전으로 자가 슬괵건의 사용이 점점 증가되고 있는 추세이다. 자가 골-슬개건-골은 이식건으로써 강한 물성, 튼튼한 고정, 장기 추시에서 높은 성공률 등으로 젊고, 강한 활동을 요하는 운동선수에서 종종 선택되고 있으며 조기에 강한 활동으로의 운동 복귀를 할 수 있다. 그러나 슬관절 전방 통증, 무릎을 꿇을 때의 통증, 슬개골골절, 슬개-대퇴 관절의 염발음 및 대퇴사두근력의 감소 등 이식물 채취로 인한 공여부 이환이 문제가 되었다. 그래서 자가 골-슬개건-골의 이식건으로서의 문제점 및 문헌상 고찰을 하여 논하고자 한다.

The lateral meniscus is morphologically more variable than the medial meniscus. An abnormal lateral meniscus also varies with respect to its size, shape and stability, and such variations can occur in any patient of any age. The most common variant is a discoid lateral meniscus. We recently encountered a patient with a discoid lateral meniscus for which the anterior horn of the meniscus was anomalously inserted into the anterior ACL. The patient was forty five years old women who had persistent pain for three to four years without any specific trauma history. She was preoperatively diagnosed as having discoid lateral meniscus by MRI, and was confirmed the presence of the complex tear and anomalous insertion of the anterior horn of the discoid lateral meniscus into the anterior ACL by arthroscopic examination. Arthroscopic subtotal meniscectomy was performed and the symptoms were improved after surgery.

일반적으로 전방 십자인대 손상의 치료만큼 관심과 논쟁의 대상이 되는 분야도 드문 것으로 알려져 있다. 치료 방법으로는 과거에는 보존적 요법이나 일차 수복술, 관절외 재건술 등이 시행되었으나, 근래에는 관절경하에 재건술이 가장 보편화되고 선호되는 방법으로 발전되어 왔다. 현재까지 400개 이상의 전방십자인대 재건술의 방법이 문헌상 발표되고 있으나 아직까지도 이상적인 방법은 없는 것으로 알려져 있다. 재건술의 성공을 위하여 환자의 선택, 수술시기, 수술방법 재건술의 기본원칙에 대한 이해 등이 중요한 요인으로 인정되며, 이에 대한 문헌고찰과 최근경향 등에 대하여 논하고자 한다.
