Effect of internal brace technique on postoperative laxity in PCL reconstruction Short term study

Abstract

The posterior cruciate ligament (PCL) is critical to the stability of the knee and is sometimes referred to as the "pivot." Multiligamentous knee injuries are the most prevalent sort of pcl injuries, however they may also be PCL injuries on their own. Pcl injuries may result from a variety of causes, including a sports injury, a car accident, or a hyperextension injury. Pcl injury in non-athletes is treated with conservative treatment for a few weeks to allow for healing of the PCL, but in cases of multi-ligamentous knee injury or complete isolated pcl injury grade 3, surgical repair or reconstruction is required to restore knee mechanics and allow healing of the pcl in a proper length and position. Injuries to the anterior cruciate ligament (PCL) can be treated surgically in a variety of ways, including a single or double bundle reconstruction, anatomical transtibial or all-inside technique, tibial inlay reconstruction, or just repair of the PCL and augmentation with an internal brace, depending on the healing power of the pcl. Post-operative laxity after posterior cruciate ligament restoration with or without internal brace augmentation was compared in this research. Thirty patients who had PCL injuries and underwent PCL repair at Benha University Hospital or the Health Insurance Hospitals were included in a prospective research to evaluate postoperative laxity. Fifteen patients had PCL repair with an internal brace and fifteen underwent PCL reconstruction without an internal brace. Results: In the first group with an internal brace, outstanding in 7 instances, good in 7 cases, and average in one case. Without internal bracing, outstanding in two instances 13.3%, good in five cases (33.3%), and fair in eight cases (53.3%) are all that can be said. Structural integrity was improved by adding an independent ST to the PCL repair, regardless of the method utilised, resulting in decreased dynamic and total elongation and increased ultimate strength. During high loads, the ST seems to be a "safety belt" that becomes more prominent, demonstrating increased plastic deformation.

Tissue Augmentation Techniques in the Management of Ligamentous Knee Injuries

“…4,10 For symptomatic Grade III or multi-ligament injuries, surgical reconstruction-most commonly with either a single or double-bundle technique-can be considered. [28][29][30][31] The utilization of suture augmentation or internal bracing in the repair or reconstruction of ligamentous injuries has become increasingly prevalent in the literature. Recent cadaveric studies have helped develop a biomechanical argument for the utilization of these techniques.…”
