acl on Linux

黑客防线 2009年第12期 57-60页

作者： Whitebe＆r@Freebear Developer Group

很多用户抱怨Linux的UGO权限模式过于粗糙．难以满足管理需要。同时，Windows因为具有灵活强大的acl机制，吸引了相当多系统管理员的注意。随着IEEE POSIX 1003.1e标准草案的出现，acl开始在FreeBSD等类UNfX操作系统上实现。

Introduction: Femoral and tibial morphology posted as anatomical risk factors for acl injuries. Samora *** found out that a decreased BIA was associated with acl rupture. Alentorn-Geli et al. found that the angle between the Blumensaat line and the anterior tibial slope (BATS angle) was significantly greater in men with acl injury. However, other authors were not able to reproduce the similar findings. Our study aimed to determine the Blumensaat inclination angle (BIA) and angle between Blumensaat line and tibial slope (BATS) in patients with or without anterior cruciate ligament injury. We also explored the factors influence them. Method: We elavuated 142 MRI knee done in Hospital Sultan Ismail from January 2017 to November 2020. Study group was patient with acl injuries, with or without meniscus and cartilage injuries. Control group was patient with no acl injuries. 57 patients with history of fracture around the knee joint, multiligamentous injuries, inflammatory arthritis and tumour were excluded from the study. We recorded their age, gender, BIA, and BATS angle. BIA and BATS angle were measured in sagittal plane MRI as described by Koji Iswasaki et al. and Alentorn-Geli et al. Result: 54 patients were in study group and 31 years in control group. The mean age for study group was 32.7 (8.95) year old, and for control group was 42.5 (14.54). The mean BIA for study group was 36.20 (4.542) degree, and control group was 37.25 (4.941). The mean BATS for study group was 36.33 (5.78) degree, and control group was 25.26 (6.047) degree. BIA and BATS angle did not differ in both groups, age and gender. Conclusion: Our study did not show BIA and BATS angle as an anatomical risk factor for acl injuries. Age and gender did not affect these angles.

Objective: To observe the accuracy and the advantages and disadvantages of the femoral tunnels made by the two techniques. Materials and Methods: We randomly summoned nineteen patients undergoing anatomic acl reconstruction in a single band technique by the same surgeon: Ten by group II (GII) and nine by Group I (GI). GI: drilling in the technical in-out. GII: drilling the technique out-in. The patients underwent a CT scan with three-dimensional reconstruction of the distal femur. Was applied the technique of quadrants described by Bernard and Hertel and optimized for position by Forsythe and observed in the femoral tunnel: the accuracy of the joint entry;posterior cortical thickness in that point;emergency lateral distance to the lateral epicondyle and the overall length. Results: The coordinates of the distances obtained average was very close, with no statistical difference comparable to that obtained by Bernard and Hertel and Forsythe. The distance from the tunnel exit to the lateral epicondyle obtained average 1.46 cm in GI and 0.47 cm in GII, with a significant statistical difference. The thickness of the posterior cortex was 3.9 mm in GI and 5.4 mm in GII, with no statistical difference. The length averaged was 3.07 cm in GI and GII in 2.94 cm, with no statistical difference. Conclusions: Both techniques allow well placed tunnels, with no statistical difference. In the technique in-out the tunnel exit is closer to the lateral epicondyle. The thickness of the posterior cortex is similar. The length of the femoral tunnel is similar and around 3 cm.

Background: The anterior cruciate ligament (acl) is the main structure that prevents the forward movement of the tibia about the femur Meniscus tear which is a common finding in patients with anterior cruciate ligament (acl) injury. Aim: To investigate the prevalence of types of meniscus tears in patients with Anterior Cruciate Ligament (acl) Injury. Methods: A retrospective study was conducted among inpatients. Clinical evaluation included side-to-side difference in anterior tibial translation (ATT) as measured by a KT-1000 arthrometer (MEDmetric Corp) and a grade of pivot-shift test at final follow-up in all patients. Subsequent meniscal tear was defined by symptoms of joint line pain and/or locking or joint effusion requiring surgical treatment. Results: Most of patients were males (92.6%). The patients were categorized into 5 groups according to age with a mean of age 32.8 ± 10.6. The most common causes of acl injury were falling down (43.2%), trauma (38.1%) or knee torsion (18.8%). Medial meniscal tear was found in 92 knees (55.7%), while lateral meniscal tear was found in 19 knees (10.8%) and the most common type was the longitudinal tear that was found in 31 knees (17.6%). Similarly, 66.7% of the meniscal flap tears and half of the meniscal bucket-handle tears were significantly associated with loose body (P Conclusion: The present study demonstrated that meniscus tears are more common in individuals with chronic acl rupture. The main factors contributing to acl injury were classified as falls, trauma, and knee torsion. Gender was identified as a critical determinant in the etiology of acl injury. The occurrence of a ramp lesion was associated longitudinal meniscal tears, whereas chodoral injury was associated with the majority of meniscal flap tears and meniscal bucket-handle tears.

The main goals of anterior cruciate ligament reconstruction (aclR) are to restore knee function and prevent development of osteoarthritis (OA). However, the incidence of early-onset OA remains higher in patients following aclR. The purpose of this study was to compare the computed tibiofemoral joint (TFJ) forces and muscle forces of aclR knees to those of BMI-matched control subjects during the stance phase of gait. We hypothesized that the use of principal component analysis would allow us to characterize alterations in three-dimensional TFJ loads and muscle forces after aclR as compared to a healthy control population. Of the eight aclR knees, four displayed an abnormal TFJ compressive force. In three of these four aclR knees that displayed abnormal compressive forces, one of the major muscles/muscle groups crossing the knee also deviated from the control group. We believe that each subject has a unique response to their injury, reconstructive surgery, and rehabilitation.
