Received: 08 October 2018; Accepted: 30 October 2018; Published: 08 November 2018. be used, it must be augmented by a reconstruction of the, involving avulsions, especially of structures torn off the, involving the capsule and the lateral meniscocapsular, ligaments that are anchored and sutured to the underlying, bone (18). Ten patients who underwent anatomic posterolateral knee reconstruction (LCL, popliteus tendon, femorofibular-based PFL reconstruction [group B]) using a split Achilles tendon allograft were recruited into a matched control group. Several techniques have been designed to address injuries of the PLC, which include open,12 arthroscopic-assisted,4 and all-arthroscopic techniques.6 Early studies of PLC repair versus reconstruction showed superior results, with reconstruction having a 9% failure rate and repair having more than a 4 times greater failure rate of 37%.13 Early studies of reconstruction … Conclusions: 0000084279 00000 n Twenty-nine of 33 patients were available for follow up at an average of 31.9 ± 12.3 months (range, 24-59 months) postoperatively. The greatest differences in ligament forces from the intact model were found in the cFBR model, whereas there were no remarkable differences between the TBR and mFBR models in both gait and squat loading conditions. technique. None of the tensioning orders restored intact knee tibiofemoral orientation. The purposes of this article are to review the current concepts of PLC injuries and to address their role in the ACL-deficient and ACL-reconstructed knee. Clinical comparison, of anteromedial versus anterolateral tibial tunnel direction, for transtibial posterior cruciate ligament reconstruction: 2. to 8 years' follow-up. Comparison of, posterolateral corner reconstructions using computer-. 0000001652 00000 n In addition, the authors’ preferred anatomic PLC reconstructions are described, either using allografts or autografts. Abstract: This manuscript intends to review and discuss the current concepts of posterolateral corner (PLC) repair and reconstruction techniques. (G) Lateral and posterior view, left knee; LCL is reproduced by one strand of the semitendinosus, one strand of the gracilis and the biceps; PFL is reproduced by one strand of the semitendinosus connecting tibia to fibula and one strand of the gracilis from the fibula to the PT femoral insertion; PT is reproduced by the bulkiest strand of the semitendinosus. During multiple knee ligament reconstructions, the graft tensioning order may influence the final tibiofemoral orientation and corresponding knee kinematics. Novel approach for reconstruction, of the posterolateral corner using a free tendon graft. 0000002388 00000 n Clinical outcomes and stability with tibiofibular-based PFL reconstruction would be better than those with femorofibular-based PFL reconstruction. Power transformer is a one such transformer whose capacity is more than 1MVA.such a transformer has to be given more importance. The risk of tunnel convergence with the ACL and PCL femoral tunnels can be reduced by adjusting the orientation of the FCL and PLT tunnels and the sMCL and POL tunnels, respectively. Knee dislocations often require multiple concurrent ligament reconstructions, which involve creating several tunnels in the distal femur. Am J Sports Med, 21. The following knee conditions were evaluated: intact, bicruciate deficient and following bicruciate reconstruction. repair and reconstruction techniques. Neutral tibial position representing tibiofemoral orientation, anterior–posterior (AP) tibial translation, varus–valgus laxity, and internal-external rotation were measured using a Microscribe 3DLX at 0°, 30°, 60°, and 90° of knee flexion. The purpose of this biomechanical study aims to quantify the effects of sequential sectioning of the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) bundles on knee laxity. Anatomic Posterolateral Knee Reconstruction Using 2, 39. (D) A 7 mm interference screw is introduced at the bular tunnel while the grafts are tensioned. posterolateral corner in the multiligament-injured knee. The semitendinosus tendon graft had been used for PCL reconstruction in some cases besides the hamstring tendon graft and provides a clinically evident reduction in symptoms and restores satisfactory stability. From reference (2). 0000020606 00000 n Laprade RF, Grifth CJ, Coobs BR, et al. Injuries to the PLC often occur in combination with other ligamentous injuries to the knee; most commonly … Historically the decision process to reconstruct or repair the ligaments or tendons is dependent on the location of the injury (medial or lateral structures) and whether the injury is acute or chronic. Orthop, 11. Clinical outcomes were evaluated using the OAK (Orthopadishe Arbeitsgruppe Knie) and IKDC (International Knee Documentation Committee) knee scoring systems. posterolateral rotatory instability on ACL reconstruction: comparison between isolated ACL reconstruction and, ACL reconstruction combined with posterolateral corner. J Bone Joint, 22. Biomechanical studies comparing, them showed improved results favoring the more anatomic, two femoral tunnels reconstruction (25,26). The purpose of this article is to review the anatomy, biomechanics, diagnosis, classification and, treatment of PLC injuries and summarize the recent literatures regarding the treatment outcomes. Aiming the FCL tunnel 35° anteriorly minimized convergence with the ACL tunnel. In this sense, stress radiographs can help to objectively determine the extent of these lesions. Nov 2018; Carlos Eduardo … Medical image processing software was used to create tunnels for each of the primary ligamentous structures, replicating a surgical approach that would be used in multiple ligament reconstructions. J Orthop Res, posterolateral instability of the knee. 0000075980 00000 n Increasing importance has been placed on the posterolateral corner (PLC) in maintaining varus and rotational stability of the knee. 0000098807 00000 n This manuscript intends to review and discuss the current concepts of posterolateral corner (PLC) repair and reconstruction techniques. This technique provides anatomical PLC reconstruction, using autografts as the semitendinosus graft is artificially. We reported a reconstructive procedure for PCL and PLC injury of the knee by using semitendinosus and gracilis tendon graft with LaPrade technique. 36. Dr. LaPrade will assess the patient’s knee alignment with a long leg x-ray. 0000011715 00000 n A Systematic, 14. On the medial side, tunnel convergence was avoided by orienting the sMCL tunnel 40° proximally and anteriorly and the POL tunnel 20° proximally and anteriorly. J Bone Joint Surg Am 2012;94:253-9. The final reconstruction reproduces the popliteus tendon with the bulkiest end of the semitendinosus; the popliteofibular ligament with a strand of the semitendinosus and a strand of the gracilis; and the lateral collateral ligament with a strand of the semitendinosus and a strand of the gracilis, which can also be augmented with a biceps strip. system. T, collision during simultaneous anterior cruciate ligament, and posterolateral corner reconstruction. A high index of suspicion is necessary when evaluating the injured knee to detect these sometimes occult injuries. lengthened by the loop of the suspensory fixation device, surpassing the need of longer allografts to do so (6). Am J Sports Med 2009;37:693-8. lesion biomechanics, Part 2-treatment using a simultaneous, tensioning protocol: ACL xation rst is better than PCL, xation rst to restore tibiofemoral orientation. During concomitant POL reconstruction, the sMCL should be aimed 40° proximally and anteriorly and the POL 20° proximally and anteriorly. There is a trend towards selecting a more "anatomical" surgical approach when treating the MLIKs. 0000103063 00000 n MVM Luzo is a consultant. Here is a set of procedures to, Aimed at the problem of structure moving in city reconstruction, study on intelligent and automatic control technology of the equipment for huge structure moving was put forward. It. PCL fixation first had a larger decrease in AP translation than ACL fixation first at 30° flexion (64.6 ± 3.5% vs. 58.3 ± 2.4%, p = 0.01). Am J, reproducibility and repeatability of varus stress, radiographs in the assessment of isolated bular collateral, ligament and grade-III posterolateral knee injuries. Complete PLC lesions rarely heal with non-operative treatment, and are therefore most often treated surgically. In a one-stage ACL and PCL reconstruction, allograft. An uncommon technique for bicruciate ligament reconstruction involving simultaneous tensioning of the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) grafts with ACL graft fixation first has been pointed out as superior to the “gold-standard” PCL graft fixation first.
