Defining a prognostic criterion of orthopaedic complications development in patients with an injury of anterior cruciate ligament of knee joint

IntroductionPrognostic indices of orthopaedic implications development were investigated among patients with anterior cruciate ligament (ACL) injuries on the basis of stabilography research during the functional period of rehabilitation.MethodsThe study included 52 randomly selected individuals with a complete ACL tear qualified for surgical reconstruction. The patients’ age was 18–59 (average: 37.8 ± 2.0) years. All participants underwent rehabilitation treatment in the Institute of Traumatology and Orthopaedics, National Academy of Medical Sciences of Ukraine, and had surgeries in the Institute’s clinics. The crural part of the graft was fixed with the assistance of either the RigidFix system or the Cross-Pin system, and the Biointrafix or Biosure Sync system was applied for the tibial part.Results and conclusionsOn the basis of the performed analysis of indices that characterize the functional condition of the injured limb of patients with an injury of ACL of knee joint at the functional stage of rehabilitation treatment, it is possible to identify a high and medium level of loading asymmetry in the lower extremities, decrease of electrobiological activity and muscle resistance ability during bending, stretching, adduction, and abduction, as the main prognostic criterion of orthopaedic complications development.

Reconstruction of anterior cruciate ligament of knee joint with single bundle allograft under arthroscopic

Objective To introduce the treatment efficacy of using allograft muscle ligament anatomical to rebuild anterior cruciate ligament(ACL) of knee joint under the arthroscopy. Methods Sixty-two cases patients with ACL rupture in anterior cruciate ligament reconstruction under arthroscopy.Allograft ligaments were used as graft, a bone tunnel was established in the proximal tibia and distal femur, and the graft was fixed by the extrusion screw.After the operation, the knee joint was fixed for 12 weeks, and the subjective evaluation was carried out according to the Lysholm and Larson knee score standards; in order to assess the stability of the ligament and the functional recovery of the knee joint, objective evaluation was carried out according to Lachman test in patients. Results The preoperative average Lysholm scale was (43.1±2.1) points, the final average score of 2 years after the reconstruction of the ligament was (91.0 + 2.3) points, there was significant difference(t=3.460, P=0.001). The preoperative average Larson scale was (41.0±2.9) points, the final average score of 2 years after the reconstruction of the ligament was (90.1±3.5) points, there was significant difference(t=3.232, P=0.001). Lachman test results were negative in 62 patients at the end of the review.No serious postoperative complications occurred, no knee infection, deep vein thrombosis and stiffness.All the patients can be completely straight 1 year after operation, knees up to 120 degrees.All patients were satisfied with the function at the end of the follow-up, no joint instability, no re-rupture occurred during the follow-up period. Conclusion Using the allogeneic single beam anatomy of anterior cruciate ligament reconstruction under arthroscopy can obtain satisfactory clinical efficacy.

The Clinical Application and Evaluation of Artificial Cruciate Ligament Materials for Knee Exercise Injury

Rupture of knee joint cruciate ligament in sports training and competition, need through the surgical method to reconstruction of ligament reconstruction function. Application of biological materials for cruciate ligament, can make patients get less disease waste, and allows the patient knee joint activities immediately after treatment, is beneficial to the rehabilitation of patients. Cruciate ligament graft materials including autograft, allograft ligament ligament and artificial ligament. Autologous tissue reconstruction of knee joint cruciate ligament with bone patellar tendon bone and semitendinosus graft, many complications of bone patellar tendon bone graft, semitendinosus and gracilis tendon transplant will affect the joint function. Allogenic ligament materials mainly include bone patellar tendon bone and four femoral head allograft tendon bone, shortage of material is not completely kill bacteria and viruses. Artificial ligament material divided into permanent ligament, ligament and ligament scaffold material framework material, the effect of LARS artificial ligament transplantation in the treatment of cruciate ligament injury is more ideal, compared with the efficacy of autologous tendon graft, the differences were significant, had no significant differences compared with the long term effect of transplantation of autologous ligament.

Application of Synthetic Substitute Materials on Reconstruction of Anterior Cruciate Ligament of Knee Joint in Exercise-Induced Injury

Exercise training or competition in anterior cruciate ligament of knee joint injury, autologous tissue, allograft materials, artificial materials and tissue engineering ACL repair and reconstruction is often used. These materials can repair and reconstruction of anterior cruciate ligament, the choice of materials involves many factors such as stability of complications after anterior cruciate ligament reconstruction and postoperative. Because of the complexity of anterior cruciate ligament of knee joint structure and function, finally to many factors combined with the site of injury, injury severity and the patient's own state cross ligament repair and reconstruction of knee joint replacement materials.

MR imaging of anteromedial and posterolateral bundles of anterior cruciate ligament of knee joint

Objective To improve the visualization of anteromedial and posterolateral bundles of anterior cruciate ligament (ACL) and investigate the optimal MRI plane for the bundles at a 3.0 T MR scanner.Methods MR images of 149 knee joints were reviewed retrospectively.Display rates of AMB,PLB and their different parts (the top portion,the middle portion and the low portion) on MR different planes including axial,sagittal and coronal planes were analyzed and their differences were compared with the x2 section method.Results There was no statistical difference in the display rates of two bundles of ACL between axial plane ( 115/149,77.2％ ) and coronal plane (103/149,69.1％ ) (x2 =2.4606,P ＞0.0125 ).Statistical differences were found between axial and sagittal plane,coronal plane and sagittal plane (21/149,14.1％ ) ( x2 =119.5138,92.8695 respectively,P ＜0.0125 ).There was a statistical difference for the top portion of ACL between axial plane ( 104/149,69.8％ ) and coronal plane,sagittal (0/149,0)and coronal planes ( 7/149,4.7％ ) ( x2 =135.081,159.7526 respectively,P ＜ 0.0125 ),between sagittal and coronal planes (x2 =7.1684,P ＜ 0.0125 ).For the middle portion of ACL,there was no statistical difference between axial plane ( 108/149,72.5％ ) and coronal plane (94/149,63.1％ ) (x2 =3.0120,P ＞ 0.0125 ),while statistical differences were found between axial and sagittal plane,coronal planes and sagittal plane ( 10/149,6.7％ ) ( x2 =134.7454,104.2173 respectively,P ＜ 0.0125 ).For the low portion of ACL,there was no statistical difference between axial plane ( 103/149,69.1％ ) and coronal plane (101/149,73.8％ ) (x2 =0.8065,P ＞0.0125),while statistical differences were detected between axial and sagittal plane,coronal planes and sagittal plane ( 18/149,12.1％ ) ( x2 =100.5300,115.9132,P ＜ 0.0125 ). The different parts of ACL displayed low intensity on different MR planes and normal morphology.Conclusions ACL can be displayed on conventional MR planes at a 3.0 T MR scanner to some extent.Axial and coronal planes might be the optimal MRI planes for ACL and its two bundles.
