The most commonly involved hand joints in RA are the MCP and PIP joints. The DIP joints are usually spared.
Which joints are least commonly involved in osteoarthritis?
OA may be defined by radiographic criteria alone (radiographic OA), typical symptoms (symptomatic OA), or by both. Using radiographic criteria, the distal and proximal interphalangeal joints of the hand have been identified as the joints most commonly affected by OA, but they are the least likely to be symptomatic.
Which joints are affected first by osteoarthritis?
Osteoarthritis primarily affects the weight-bearing joints, that is to say, those of the hip, knee and spine. Some non weight-bearing joints, such as those of the fingers and thumb, can also be affected.
What is osteoarthritis of the joint?
Osteoarthritis is the most common form of arthritis, affecting millions of people worldwide. It occurs when the protective cartilage that cushions the ends of the bones wears down over time. Although osteoarthritis can damage any joint, the disorder most commonly affects joints in your hands, knees, hips and spine.
Does osteoarthritis affect joints symmetrically?
It often affects small and large joints on both sides of the body (symmetrical), such as both hands, both wrists or elbows, or the balls of both feet.
Is osteoarthritis bilateral or unilateral?
Some people get OA in just one knee, which is known as unilateral OA. Bilateral knee arthritis occurs when both knees are affected with OA. OA is a painful, degenerative condition that can reduce your mobility and make daily tasks difficult to manage.
What is ankle osteoarthritis?
Ankle osteoarthritis is the occurrence of osteoarthritis (OA) in the ankle joint. The ankle joint consists of two synovial joints, namely the talocrural joint and the subtalar joint. In both joints osteoarthritis can be diagnosed in the medial and the lateral compartment.
Which joints are affected by arthritis?
The joints involved most frequently are the proximal interphalangeal (PIP) and metacarpophalangeal (MCP) joints of the hands, the wrists, and small joints of the feet including the metatarsophalangeal (MTP) joints. The shoulders, elbows, knees, and ankles are also affected in many patients.
Can osteoarthritis spread from one joint to another?
While OA can be limited to a single joint, in many cases it progresses to involve other joints, often in a sequential fashion as you describe. In some cases, pain from OA in one joint (such as an ankle or knee) can prompt you to walk, stand or move differently.
Which part of the joint is affected by arthritis?
Inflammation begins in the joint lining and then damages both cartilage and bone. Rheumatoid arthritis often affects the same joints on both sides of the body. Hands, wrists, feet, knees, ankles, shoulders and elbows can be affected.
What is a Tibiotalar joint?
The ankle joint is also called the tibiotalar joint. It’s where the shinbone (tibia) rests on top of a bone of the foot called the talus. The ankle also includes the subtalar joint. This is where 2 foot bones called the talus and the calcaneus meet. Arthritis can affect these 2 joints in the foot.
What cartilage is in the ankle?
The ankle is a complex joint consisting of the tibia, talus, and fibula bones. The most common bone in the ankle to have cartilage injury is the talus. The cartilage of the talus is like any other articular cartilage and is arranged similarly to that in other weight-bearing joints.
Why osteoarthritis is common in knee joints?
In osteoarthritis, the cartilage in the knee joint gradually wears away. As the cartilage wears away, it becomes frayed and rough, and the protective space between the bones decreases. This can result in bone rubbing on bone, and produce painful bone spurs.
Is osteoarthritis usually bilateral?
Bilateral knee osteoarthritis is very common with time, as the majority of sufferers will eventually develop radiographic disease in both knees.
What is the difference between primary and secondary osteoarthritis?
This type of osteoarthritis is typically seen in people above the age of 55. It is believed that if we all live long enough, at some point, everybody will be affected by primary osteoarthritis. Secondary Osteoarthritis: Osteoarthritis in this form develops due to a specific cause such as injury or another disease.
How is osteoarthritis different from RA?
The main difference between osteoarthritis and rheumatoid arthritis is the cause behind the joint symptoms. Osteoarthritis is caused by mechanical wear and tear on joints. Rheumatoid arthritis is an autoimmune disease in which the body’s own immune system attacks the body’s joints.
What type of arthritis affects large joints?
Osteoarthritis is the most common type of arthritis and is usually caused by the overuse of joints, weather through physical activity, obesity or injuries – both past and present. This condition usually affects the weight-bearing joints, like knees, hips, feet and the spine and usually comes on gradually.
Which of the following is an example of an Amphiarthrodial joint?
Example: skull sutures. Slightly movable joints, i.e., amphiarthrodial joints. Example: tibia and the fibula joint.
What are the main causes of osteoarthritis?
What Causes Osteoarthritis?
- Heredity. Some people have an inherited defect in one of the genes responsible for making cartilage. …
- Obesity. Obesity increases the risk for osteoarthritis of the knee, hip, and spine. …
- Injury. Injuries contribute to the development of osteoarthritis. …
- Joint overuse. …
- Other diseases.
What are the 4 stages of osteoarthritis?
The four stages of osteoarthritis are:
- Stage 1 – Minor. Minor wear-and-tear in the joints. Little to no pain in the affected area.
- Stage 2 – Mild. More noticeable bone spurs. …
- Stage 3 – Moderate. Cartilage in the affected area begins to erode. …
- Stage 4 – Severe. The patient is in a lot of pain.

What is knee joint?
The knee is a joint where the bone of the thigh (femur) meets the shinbone of the leg (tibia). The knee is the largest joint in the body. It acts like a hinge, allowing the knee to flex (bend) and extend (straighten).
