Posterolateral (PLC) and posteromedial (PMC) corners of the knee represent complex anatomic regions because of intricate soft tissue and osseous relationships in small areas. Concise knowledge of these relationships is necessary before approaching their evaluation at imaging. Magnetic resonance imaging offers an accurate imaging diagnostic tool to establish normal anatomy and diagnose and characterize soft tissue and osseous injury. It is important to carefully evaluate the PLC and PMC structures on magnetic resonance imaging before planned surgical intervention to avoid potential complications resulting from occult injury.

The posteromedial corner of the knee (PMC) is an important anatomic structure that is easily seen but often overlooked on magnetic resonance (MR) images. Whereas the posterolateral corner has been ref...
Injury to the cruciate ligaments of the knee commonly occurs in association with posterolateral instability, which can cause severe functional disability including varus, posterior translation, and ex...
The medial collateral ligament (MCL) is the most commonly injured knee ligament. Most will heal well with nonoperative treatment. However, not all medial knee injuries are the same. A detailed physica...
The medial collateral ligament is the most commonly injured ligament in the knee. High-grade medial collateral injuries are associated with injuries to the posteromedial structures of the knee. Chroni...
Medial-sided knee injuries are very common, the medial collateral ligament being the most commonly injured ligament of the knee. Injuries to the medial side of the knee can occur in isolation or conco...
The proposed research will evaluate the efficacy of an intervention in urban corner stores. Community-based, environmental manipulation of corner stores is an understudied area and represe...
The purpose of this study is to use better magnetic resonance imaging (MRI) techniques to examine the knee and the bony and soft tissue changes so as to better predict the progression of o...
This study evaluates the the anatomic factors of the knee that may predispose to ACL injury.
The anterior cruciate ligament (ACL) is located inside the knee joint and provides stability to the knee. ACL injuries occur more frequently in women than men; the reason for this is unkno...
This study is to provide additional data to support the safety and efficacy of OP-1 Putty as a replacement for autograft in patients undergoing posterolateral spinal fusion.
Injuries to the knee or the knee joint.
A strong ligament of the knee that originates from the posteromedial portion of the lateral condyle of the femur, passes anteriorly and inferiorly between the condyles, and attaches to the depression in front of the intercondylar eminence of the tibia.
Replacement for a knee joint.
Injuries to blood vessels caused by laceration, contusion, puncture, or crush and other types of injuries. Symptoms vary by site and mode of injuries and may include bleeding, bruising, swelling, pain, and numbness. It does not include injuries secondary to pathologic function or diseases such as ATHEROSCLEROSIS.
