Arthrofibrosis of the knee is a condition whereby knee motion is limited due to scar tissue, contractures after injury or surgery, or due to the effects of osteoarthritis over time. There are 2 types of motion that we usually think of as being important to assess knee arthrofibrosis. First, a lack […]
Knee pain is a debilitating symptom associated with knee injuries. While some knee injuries are cut and dry, others are not. Knee pain may derive from damage to the soft tissue or connective tissue of the knee joint, as well as from one or more of the nerves that reside within the knee. While these […]
Tibial plateau fractures are caused by a force driving the lower end of the femur (thigh bone) into the soft bone of the tibial plateau.
One area of the knee that is not discussed as often as some of the other components, is a section called the trochlea. This area of the knee is easy to identify. When the knee is bent, the undersurface of the kneecap (the patella) lies in an area known as […]
In the past, any type of pain over the anterior aspect of the knee was commonly called patellofemoral chondromalacia. However, patellofemoral chondromalacia is a specific term describing a particular pathology/injury that should only be used in cases with this problem.
Chondromalacia, or damage to the cartilage, is the formation of early arthritis. Any […]
Lateral patellar instability is almost always due to a patellar (kneecap) dislocation. In this circumstance, an athlete or patient will experience their kneecap slipping out of the lateral (outside) aspect of their knee. It almost always occurs with the knee straight or at shallow degrees of knee flexion rather than with […]
A bipartite patella forms when a portion of the patella does not completely heal along the bony edges of the patella. Most commonly, this is in the upper and outer (superolateral) portion of the patella. Bipartite patella is quite common, usually asymptomatic, and is found in 2% of the population on x-rays. […]
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 […]
