The patella, or kneecap, is one of the three bones that make up the knee joint, residing near the tibia (shinbone) and femur (thigh) bones. Located directly on top of the knee as a large, round structure, it is an important part of the knee joint because it provides leverage on top of the knee […]
The posterior horn of the lateral meniscus includes the main body of the lateral meniscus, posterior to the popliteus tendon, and its root attachment on the posterior aspect of the tibia.
The lateral meniscus is even more important than the medial meniscus for shock absorption. It has been […]
The posterior horn of the medial meniscus is that portion of the medial meniscus in the back part of the knee. It varies from the main weightbearing portion of the meniscus up to where it attaches on the tibia at its lateral aspect, called the root attachment.
The posterior […]
Both the medial and lateral menisci have a stout attachment at their very posterior aspects, which are called the root attachments. These root attachments are important because they hold the meniscus in place, provides stability to the circumferential hoop fibers of the meniscus, and prevents meniscal extrusion.
When there is […]
The menisci of the knee joint are made of tough, fibrous cartilage that conform to the surfaces of the bones upon which they rest. One meniscus is on the inside of the knee (known as the medial meniscus), and the other rests on the outside of the knee (known as the […]
The lateral meniscus is an essential shock absorber on the outside (lateral) aspect of the knee joint. It absorbs about 70% of the shock of the lateral compartment. Lateral meniscal tears are not as common as medial meniscus tears. This is because the lateral meniscus is more mobile and not secured […]
The medial meniscus is an important shock absorber on the inside (medial) aspect of the knee joint. It absorbs about 50% of the shock of the medial compartment. Thus, when there is a medial knee injury such as a medial meniscus tear, it is very important to try to repair the […]
Meniscus injuries of the knee – commonly meniscus tears or meniscus strains – are common among both athletes and non-athletes. A meniscus injury or a lack of a meniscus can lead to osteoarthritis.
The knee […]
The lateral collateral ligament (LCL), also called the fibular collateral ligament (FCL), is the main structure on the lateral, or outside, portion of the knee to prevent the knee from gapping open. The term fibular collateral ligament (FCL) is more anatomically correct, but this ligament is more commonly referred […]
An injury to the proximal tibiofibular joint is rather rare, but can be debilitating in patients who have symptoms.
The proximal tibiofibular joint is located between the lateral tibial plateau of the tibia, and the head of the fibula. Typically, the proximal tibiofibular joint is injured in a fall when the […]
