Disease relevance of Posterior Cruciate Ligament

• Retention versus sacrifice of the posterior cruciate ligament in total knee replacement for treatment of osteoarthritis and rheumatoid arthritis [1].
• This paper describes the case of a 19-year-old male with ruptures of the anterior (ACL) and posterior cruciate ligament (PCL) along with the loss of the medial meniscus due to knee dislocation [2].
• PURPOSE: The purpose of this study was to evaluate the clinical outcome after 1-stage reconstructions of the anterior and posterior cruciate ligaments (ACL, PCL) with reconstruction of the posterolateral corner (PLC) structures using autogenous hamstring grafts in chronic knee injuries [3].

High impact information on Posterior Cruciate Ligament

• The anterior and posterior cruciate ligaments (ACL and PCL) were demonstrated by sagittal spin echo (SE) images through the intercondylar notch (TE = 30 ms; TR = 2,000 ms) [4].
• CLINICAL RELEVANCE: Damage to the posterior capsule may contribute to the residual posterior laxity noted clinically after posterior cruciate ligament reconstruction [5].
• The purpose of the present study was to determine the effect of the angle of the femoral and tibial tunnels in the coronal plane and incremental excision of the posterior cruciate ligament on the tension of an anterior cruciate ligament graft during passive flexion [6].
• The posterior cruciate ligament was a continuum of fibers rather than two distinct bundles, and its attachment showed variability in shape and thickness, extending past the midline in the notch (11:21 +/- 15 minutes to 4:12 +/- 20 minutes, right knee) [7].
• In the contralateral posterior cruciate ligament, the dermatan sulfate disaccharides increased significantly between Weeks 52 and 104 [8].

Anatomical context of Posterior Cruciate Ligament

• Eleven elastic elements were used to describe the mechanical behavior of the anterior and posterior cruciate ligaments (ACL and PCL), the medial and lateral collateral ligaments (MCL and LCL), and the posterior capsule [9].
• A technique is described whereby a small island of bone at the posterior midline of the tibia is preserved during total knee replacement to protect the insertion of the posterior cruciate ligament [10].
• The highest density of AChE-positive nerve fibres was noticeable in the fibular collateral ligament followed by the tibial collateral ligament, the posterior cruciate ligament, the anterior cruciate ligament and the articular capsule [11].

Associations of Posterior Cruciate Ligament with chemical compounds

• Our results suggest that high graft tension in flexion is caused by impingement of the graft against the posterior cruciate ligament, which results from placing the femoral tunnel medially at the apex of the notch in the coronal plane [6].
• In the autograft, glycosaminoglycans and chondroitin sulfate disaccharides increased significantly to about 144% and 172%, respectively, of the contralateral posterior cruciate ligament at Week 104 [8].
• Methodist Sports Medicine Center's experience with acute and chronic isolated posterior cruciate ligament injuries [12].
• The posterior cruciate ligament always broke at one of the two sites of attachment to the bone and the maximum load value at these points was decreased after local cortisol treatment [13].
• The Okayama Mark II prosthesis, which requires the posterior cruciate ligament (PCL) to be resected, was used in 83 knees (group I), the Mark II prosthesis, which allows the PCL to be retained, was used in 68 knees (group II), and the new Okayama PCL-R prosthesis, which also allows the PCL to be retained, was used in 41 (group III) [14].

Gene context of Posterior Cruciate Ligament

• Factors affecting the region of most isometric femoral attachments. Part I: The posterior cruciate ligament [15].
• The tensions were measured using the buckle transducer attached to the anteromedial band of the anterior cruciate ligament [ACL (am)], the posterior fibers of the posterior cruciate ligament [PCL (pf)], the long fibers of the medial collateral ligament [MCL (lf)], and in the total lateral collateral ligament [LCL] [16].
• We established a simultaneous reconstruction method for ruptured anterior and posterior cruciate ligaments (ACL, PCL) using a single-incision technique [17].
• In the rheumatoid arthritis group with posterior cruciate ligament retention, there was an increased incidence in posterior instability and recurvatum deformity, resulting in an increased revision rate [18].
• Injuries to the posterior cruciate ligament (PCL) are an uncommon but significant instability pattern that eventually deteriorates the articular surface of the PLC-deficient knee [19].

Analytical, diagnostic and therapeutic context of Posterior Cruciate Ligament

• Thus, the amount of dermatan sulfate disaccharides was similar in both the autograft and the contralateral posterior cruciate ligament after 2 years [8].
• Long-term results of retention of the posterior cruciate ligament in total knee replacement in rheumatoid arthritis [20].
• The objective of the present study was to evaluate posterior cruciate ligament retention in total knee arthroplasty for patients with rheumatoid arthritis to determine long term ligamentuous stability [21].
• We studied how the location of an articulated external fixator, the EBI-Orthofix (EBI Corp, Persippany, NJ), affects the kinematics of the posterior cruciate ligament (PCL)-deficient knee [22].
