Joint is a structure that separates two or more adjacent elements of the skeletal system. Depending on the type of joint, such separated elements may or may not move on one another. This section discusses the joints of the human body.
Major weight bearing joints are Knee joints and Hip joints.
The Knee Joint:
The knee is the largest and one of the strongest joints in the body. It is also delicate and complex. It joins the thigh with the leg and is made up of bones, ligaments, tendons, and cartilage. It consists of two joints: one between the femur and tibia and another between the femur and patella.
The knee is classified as a pivotal hinge joint, meaning it can straighten and bend in one direction while it allows some twisting to occur. This is known as flexion and extension; you will often hear your surgeons refer to this when discussing your knee.
Movements at the knee joint are essential to everyday life such as walking, climbing stairs, standing and sitting. Because it is such an integral part of normal activity, the knee is often susceptible to injuries and arthritis.
An individual faces normal wear and tear of the joints throughout their life. However, when this wear and tear is chronic it leads to joint damage which gives inconvenience to an individual while performing their routine activities. The joint damage depending upon the type and severity can be categorized as Arthritis.
Arthritis is most commonly caused due to aging, “wear and tear,” injury, disease, and developmental abnormalities in the joint’s structure. There are over 100 different types of arthritis.
Types of Arthritis
Osteoarthritis, Post-Traumatic Arthritis, and Rheumatoid Arthritis are types of arthritis that frequently develop in the knee
Physical examination: Medical history, symptoms, and level of pain, muscle strength, joint motion, and knee alignment. Blood tests and other laboratory tests
Radiographic Evaluation: X-rays, Magnetic Resonance Imaging (MRI)
