Anterior Cruciate Ligament (ACL) plays an important biomechanical role for the stability of knee joint. ACL injury often leads to injuries of articular cartilage, menisci, or other supporting structures, and subsequent development of degenerative arthritis. Controversies still exist in the best treatment modalities of ACL injuries. hut the author considers it most important to make the appropriate patient selection for operative reconstruction or nonoperative treatment. and describes the treatment principles of ACL injury, including diagnosis, patient selection and the treatment modalities for successful treatment of ACL injury.

Background: The purpose of this study was to identify the comparison of the muscle contractile properties on lower extremity between non-injury and injury in subjects with anterior cruciate ligament reconstruction (ACLR). Methods: Twenty-four subjects on the post-operative ACLR participated in this study. Measurement method were using tensiomygraphy to analyze the displacement maximum(Dm) and contraction time(Tc) on the both quadriceps. Results: Compared difference of the Dm between non-injury and injury, the rectus femoris (RF) and vastus lateralis (VL) increased significantly (p<.01). However, vastus medialis (VM) no significantly difference between non-injury and injury. Compared difference of the Tc between non-injury and injury, the RF increased significantly (p<.01) but VL and VM no significantly difference between non-injury and injury. Conclusions: These findings suggest that occurred muscle atrophy of the RF and VL and change properties of muscle fibers on the RF from fast muscle fibers to slow muscle fibers on the injury side of post-operative ACLR. Therefore, when apply to rehabilitation of lower extremity for post-operative ACLR, we should consider the enhance of RF and VL on injury side.

Purpose: The purpose of this study was to identify changes in knee muscle strength after reconstruction of the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL). Methods: Thirteen subjects (males) with anterior ligament injury and ten subjects (males) with posterior ligament injury voluntarily participated in this study. Both groups were evaluated at the pre-and post-reconstruction stages using an isokinetic dynamometer. Peak torque, total work, and the hamstrings to quadriceps (H/Q) peak torque ratio were calculated at angular velocities of 60°/sec and 180°/sec. Statistical analysis was conducted on SPSS 18.0 for Windows using t-tests to compare mean differences. Results: At an angular velocity of 60°/sec, both the ACL and PCL groups showed a significant increase in muscle strength in the flexors and extensors. Muscle strength in the extensors was significantly increased in the PCL group compared to the ACL group. At an angular velocity of 180°/sec, the ACL group showed a significant increase in muscle endurance in the flexors and extensors, and the PCL group showed a significant increase in muscle endurance in the flexors. At angular velocities of 60°/sec and 180°/sec, the H/Q peak torque ratio increased in the ACL group but decreased in the PCL group. Consequently, the H/Q peak torque ratio was significantly different for the two groups. Conclusion: The results suggest that the patients with ACL injury should focus on strengthening the knee extensors and that the patients with PCL injury need to strengthen the knee flexors.

In the present paper the current clinical knowledge about proprioception is given for the shoulder, knee, ankle, elbow and the radiocarpal joint. Proprioceptive capabilities are decreased after knee joint injury such as anterior cruciate ligament. Joint position sense is significantly improved by cruciate reconstruction. Thus, we review of the articles for the proprioception of the anterior cruciate ligament of the knee joint. The present information on proprioception will influence our clinical practice in the future. We should choose surgical procedures that not only reconstruct the anatomy, but also the neurophysiologic feed-back mechanism.

In volleyball, the most common injuries are anterior cruciate ligament (ACL) tears. For this reason, volleyball players frequently use knee brace as prophylactic and rehabilitation measures. The purpose of the study was to investigate the effects of knee brace on anterior cruciate ligament injuries risk factors during spike take off in female volleyball players. Fifteen female volleyball players were recruited and performed randomly spike take off with and without knee brace. Kinematics and ground reaction data were collected to estimate the anterior cruciate ligament injuries risk factors. The ACL risk factors are knee maximum flexion angle, thigh maximum adduction angle, thigh maximum internal rotation angle, shank maximum abduction angle, shank maximum external rotation angle, knee maximum extension moment and knee maximum abduction moment. Data were analyzed with paired samples t-test with Bonfferoni collection. Female volleyball players with knee brace had no significant results in knee maximum flexion angle, thigh maximum adduction angle, thigh maximum internal rotation angle, shank maximum abduction angle and shank maximum external rotation angle compare to without knee brace. Female volleyball players, however, with knee brace showed more reduced knee maximum extension moment and knee maximal abduction moment than without knee brace. In conclusion, Female volleyball players with knee brace reduced anterior cruciate ligament stress.

Objectives The objective of the study is to review the Korean traditional medicine treatment used in cruciate ligament injury. Methods According to patients, treatment methods, research design, evaluation tools, outcome, we searched for studies which performed Korean traditional medical treatment on patient with cruciate ligament injury. Results In 11 studies, total number of patents were 78. Patients were conducted with 11 kinds of treatment, which is acupuncture, herbal medicine, pharmacopuncture, electro-acupuncture, burning acupuncture, moxibustion, physiotherapy, exercise, Chuna and cupping. The most commonly used measurement was visual analog scale. Conclusions Throughout the study, we could organize Korean traditional medicine treatment for patient with cruciate ligament injury. However it is difficult to figure out among the 11 intervention which interventions were effective in improving symptom. Therefore, further researches like randomized clinical trial and systematic review is needed in order to enhance the evidence of the Korean traditional medicine.

Anterior cruciate ligament tear is a common disease of knee injury. We report 1 case of anterior cruciate ligament complete tear diagnosed by MRI(magnetic resonance imaging) imaging and 1 case after reconstruction. Outcomes were measured by visual analogue scale(VAS) and Lysholm knee scoring scale. We applied acupuncture treatment, bee venom injection, bongchuna and prescribed herbal medication. Patients who treated by oriental medical treatments had a significant effect on the pain decrease and range of motion and knee function. Oriental medical treatments are very useful on pain reduction and prevention of muscle contraction, leading to satisfied rehabilitation, as wee as diminishing recurrence after operation.

The natural history of the anterior cruciate ligament(ACL)-deficient knee remains controversial. although numerous investigation have tried to ascertain the course that the knee would follow once the ACL has lost functional integrity. An extensive review of the literature performed according to symptoms. physical examinations, associated surrounding tissue injuries. returns to activity level and radiological changes in the knee joint. An active individual with a non-functioning ACL was susceptible to injury to the menisci and deteriorate the articular cartilage, followed radiographic changes. An activity levels in general also changed after injury. The most common symptom was pain. But instability varied in these individuals. Conclusively we believe that all these factors will eventually, if not initially, result in a symptomatic knee. which will result in significant limitations to the individual's desired level. So we recommend an aggressive approach in person who desired to return to a relatively active life style in young person as well as in middle aged individuals who have significant symptomatic ACL deficient knee.

The purpose of this study was to investigate the effects of landing tasks on the anterior cruciate ligament (ACL) injury risk factors in female basketball players. Fifteen female basketball players performed a drop landing and a drop landing with a vertical jump on the 40 cm height box. Three-dimensional motion analysis system and ground reaction force system was used for calculate the ACL injury risk factors. Paired samples t-test with Bonfferoni correction were performed. The drop landing with a vertical jump had the higher knee flexion angle, peak knee varus moment, trunk flexion angle than a drop landing. However, the drop landing had the higher trunk rotation angle than a drop landing with a vertical jump. These results indicate that seemingly minor variations between drop landing and drop landing with a vertical jump may influence the ACL injury risk factors. Caution should be used when comparing studies using different landing tasks.
