ACL and Posterolateral Corner Injuries


Abstract

The importance of the posterolateral corner (PLC) with respect to knee stability, particularly in the setting of anterior cruciate ligament (ACL) deficiency, has become more apparent in recent years. The purposes of this article are to review the current concepts of PLC injuries and to address their role in the ACL-deficient and […]

Utilization of Transtibial Centralization Suture Best Minimizes Extrusion and Restores Tibiofemoral Contact Mechanics for Anatomic Medial Meniscal Root Repairs in a Cadaveric Model


Background

Although posterior medial meniscal root (PMMR) repairs are often successful, postoperative meniscal extrusion after a root repair has been identified as a potential clinical problem.

Purpose/Hypothesis

The purpose was to quantitatively evaluate the tibiofemoral contact mechanics and extent of meniscal extrusion after a PMMR repair. It was hypothesized that the addition of a centralization suture (into […]

Quantitative and Qualitative Assessment of Posterolateral Meniscal Anatomy: Defining the Popliteal Hiatus, Popliteomeniscal Fascicles, and the Lateral Meniscotibial Ligament


Background:

Surgical treatment of lateral meniscal tears can be challenging due to the greater mobility of the lateral meniscus, thin capsule, and management of the popliteal hiatus. There has been a lack of quantitative assessments of the structural attachments to the posterior horn of the lateral meniscus (PHLM) to guide repairs.

Purpose:

To qualitatively and quantitatively describe […]

Platelet-Rich Plasma for Patellar Tendinopathy: A Randomized Controlled Trial of Leukocyte-Rich PRP or Leukocyte-Poor PRP Versus Saline


Background:

A small number of randomized controlled trials have found ultrasound-guided injection of platelet-rich plasma (PRP) to be no more effective than saline for several tendinopathies; limited information exists for patellar tendinopathy. In addition, different PRP formulations that produce varying concentrations of leukocytes have not been directly compared for patellar tendinopathy.

Purpose/Hypothesis:

To determine if a single […]

Use of Platelet-Rich Plasma Immediately After an Injury Did Not Improve Ligament Healing, and Increasing Platelet Concentrations Was Detrimental in an In Vivo Animal Model

Background: Limited information in basic science and clinical trials exists to determine if ligament healing may be accelerated with the use of biological adjuvants, such as platelet-rich plasma (PRP). However, there has been widespread acceptance of PRP for use in clinical practice, despite an inadequate understanding of its biological […]

Do Tibial Plateau Fractures Worsen Outcomes of Knee Ligament Injuries?

2017 AJSM

Tibial plateau fractures account for approximately 1% of all fractures; however, these fractures can pose a surgical challenge when occurring concomitantly with ligament injuries. Delamarter first described the patterns of ligament injuries associated with tibial plateau fractures, reporting that lateral tibial plateau fractures most commonly occurred with medial […]

An Evidence-Based Approach to the Diagnosis and Treatment of Meniscal Root Tears

The purpose of this review was to summarize recent advances in the diagnosis and treatment of meniscus root tears. Over the past decade, meniscal root tears have become increasingly recognized as a significant source of pain and disability. Meniscal root tears are often caused by chronic degenerative changes […]

Biomechanical Role of Lateral Structures in Controlling Anterolateral Rotatory Laxity: The Anterolateral Ligament

2017 Elsevier – Operative Techniques in Orthopaedics

Recent renewed interest in the anatomy of the anterolateral complex of the knee, combined with concern regarding persistent instability after anterior cruciate ligament reconstruction, has led to an expansion of the literature on the biomechanics of many structures of the anterolateral complex of […]

Demographics and Injuries Associated With Knee Dislocation

2017 OJSM

Few studies have reported on the incidence, injury mechanisms, ligament injury patterns, and associated injuries of knee dislocations. Most studies are retrospective in nature, and few patients are included. The incidence of these injuries is reported to be between 0.02% and 0.2% of all orthopaedic injuries. There is […]
