Introduction
The knee and ankle joints are some of the most important joints in the human body. The knee joint, composed of bones, ligaments, tendons and muscles, supports the body's weight and allows movement of the leg. Meanwhile, the ankle joint enables foot movements such as dorsiflexion and plantarflexion. This article will showcase a collection of images that demonstrate different angles of knee and ankle joint extension.
Anatomy of the Knee Joint
The knee joint is comprised of the femur, tibia, and patella, which are supported by various ligaments and tendons. As the largest joint in the body, it allows for flexion and extension, as well as rotation of the leg. The following images showcase the different angles of knee joint extension:

Anatomy of the Ankle Joint
The ankle joint is composed of the tibia, fibula, and talus, and is supported by various ligaments and tendons. It allows for dorsiflexion and plantarflexion, as well as inversion and eversion. The following images showcase the different angles of ankle joint extension:

Common Knee Injuries
The knee joint is susceptible to a variety of injuries, ranging from minor to severe. Some of the most common knee injuries include:
1. ACL Tear
The anterior cruciate ligament (ACL) is responsible for stabilizing the knee joint. When this ligament is torn, it can cause pain, swelling, and instability in the knee. ACL injuries are most commonly caused by sports-related activities.
2. Meniscus Tear
The meniscus is a piece of cartilage that acts as a cushion between the femur and tibia. When it is torn, it can cause pain, swelling, and stiffness in the knee. Meniscus tears are often caused by twisting or sudden movements.
3. Patellar Tendinitis
The patellar tendon connects the kneecap to the shinbone. When this tendon becomes inflamed, it can cause pain and tenderness in the knee. Patellar tendinitis is most commonly caused by overuse.
Common Ankle Injuries
The ankle joint is also susceptible to a variety of injuries. Some of the most common ankle injuries include:
1. Ankle Sprain
An ankle sprain occurs when the ligaments that support the ankle joint are stretched or torn. This can cause pain, swelling, and difficulty walking. Ankle sprains are most commonly caused by sports-related activities or uneven surfaces.
2. Achilles Tendinitis
The Achilles tendon connects the calf muscle to the heel bone. When this tendon becomes inflamed, it can cause pain and stiffness in the ankle. Achilles tendinitis is most commonly caused by overuse.
3. Peroneal Tendinitis
The peroneal tendons are responsible for stabilizing the ankle joint. When they become inflamed, it can cause pain and swelling in the ankle. Peroneal tendinitis is most commonly caused by overuse or injury.
Conclusion
Overall, the knee and ankle joints play a vital role in the body's movement and stability. It is important to take care of these joints and seek medical attention if any pain or injury occurs. With proper care and attention, we can maintain healthy and functional knee and ankle joints for many years to come.
