Combined Posterior Cruciate Ligament and Superficial Medial Collateral Ligament Knee Reconstruction: Avoiding Tunnel Convergence


Abstract

Combined posterior cruciate ligament (PCL) and medial collateral ligament (MCL) injuries represent a complex
pathology that requires a thorough clinical and radiographic examination to diagnose and identify all injured structures.
Anatomic reconstruction of the injured ligaments is recommended, including double-bundle PCL reconstruction and
superficial MCL augmentation. In the setting of this complex reconstruction, several technical aspects require […]

Editorial Commentary: Arthroscopic Outcomes Are Equal to Open Popliteus Tendon Reconstructions, but Do Not Forget That the Goal Is a Stable Posterior Cruciate Ligament Reconstruction


Abstract:

Arthroscopic popliteus tendon reconstructions were found to be equally as efficacious as open popliteus reconstructions in restoring external rotation stability. However, when the procedure was combined with a posterior cruciate ligament (PCL) reconstruction, the PCL reconstruction still had increases of 4 to 5 mm of posterior tibial translation in side-to-side differences on posterior stress radiographs. […]

Quantitative mapping of acute and chronic PCL pathology with 3 T MRI: a prospectively enrolled patient cohort


Background

The diagnosis of incomplete acute and chronic posterior cruciate ligament (PCL) tears can be challenging with conventional magnetic resonance (MR) imaging, particularly for injuries in which the ligament appears continuous as occurs with chronic PCL tears that have scarred in continuity. Quantitative mapping from MR imaging may provide additional useful diagnostic information in these […]

Tibial Slope and Its Effect on Graft Force in Posterior Cruciate Ligament Reconstructions


Background:

A flattened posterior tibial slope may cause excessive unwanted stress on the posterior cruciate ligament (PCL) reconstruction graft and place patients at risk for PCL reconstruction graft failure. To date, there is a paucity of biomechanical studies evaluating the effect of posterior tibial slope on the loading properties of single-bundle (SB) and double-bundle (DB) […]

Tibial Slope and Its Effect on Graft Force in Posterior Cruciate Ligament Reconstructions

Decreased Posterior Tibial Slope Does Not Affect Postoperative Posterior Knee Laxity After Double-Bundle Posterior Cruciate Ligament Reconstruction

Background

Recent clinical studies identified sagittal plane posterior tibial slope as a risk factor for increased postoperative lax- ity after single-bundle posterior cruciate ligament reconstruction (PCLR).

Purpose/Hypothesis

To retrospectively compare the degree of posterior tibial slope and its effect on posterior tibial translation (PTT) after double-bundle (DB) PCLR. Our null hypothesis was […]

Decreased Posterior Tibial Slope Does Not Affect Postoperative Posterior Knee Laxity After Double-Bundle Posterior Cruciate Ligament Reconstruction

Posterior Tibial Slope and Risk of Posterior Cruciate Ligament Injury

Background

Recent biomechanical studies have identified sagittal plane posterior tibial slope as a potential risk factor for pos- terior cruciate ligament (PCL) injury because of its effects on the kinematics of the native and surgically treated knee. However, the literature lacks clinical correlation between primary PCL injuries and decreased posterior […]

Posterior Cruciate Ligament: Current Concepts Review

ABJS 2018

The posterior cruciate ligament (PCL) is the largest and strongest ligament in the human knee, and the primary posterior stabilizer. Recent anatomy and biomechanical studies have provided an improved understanding of PCL function. PCL injuries are typically combined with other ligamentous, meniscal and chondral injuries. Stress radiography […]

Posterior Cruciate Ligament Injuries of the Knee at the National Football League Combine: An Imaging and Epidemiology Study

Purpose: To determine the epidemiology by player position, examination, imaging findings, and associated injuries of posterior cruciate ligament (PCL) injuries in players participating in the National Football League (NFL) Combine.

Methods: All PCL injuries identified at the NFL Combine (2009-2015) were reviewed. Data were obtained from the database organized by […]

Anatomic Posterior Cruciate Ligament Reconstruction: State of the Art

JISAKOS 2016

The posterior cruciate ligament (PCL) is recognized to be the main posterior stabilizer of the knee. PCL injuries are most commonly associated with concurrent ligament injuries and also with a high prevalence of chondral and meniscal injuries. Recent evidence of the accuracy of the stress radiographs as […]

Quantifiable Imaging Biomarkers for Evaluation of the Posterior Cruciate Ligament Using 3-T Magnetic Resonance Imaging


OJSM 2016

Quantitative magnetic resonance imaging (MRI) techniques, such as T2 and T2 star (T2*) mapping, have been used to evaluate ligamentous tissue in vitro and to identify significant changes in structural integrity of a healing ligament. These studies lay the foundation for a clinical study that uses quantitative mapping to evaluate ligaments in vivo, […]
