How Does Osteoarthritis In The Knee Affect My Body
Knee pain is the most common symptom of osteoarthritis in the knee, making it painful for you to jog, run, climb stairs or kneel. It can also make your knees feel stiff or swollen. Over time, osteoarthritis of the knee can change the shape of your knee joint, making your joint feel unstable or wobbly.
What Are The Symptoms Of Osteoarthritis In The Knee
Pain is the most common symptom of osteoarthritis in the knee. Your knee might hurt when you move it, or even when you are just sitting still. Other symptoms are:
- Your knee feels stiff, particularly when you first get up or when youve been sitting for a long time.
- Your knee looks swollen or feels puffy.
- You hear a cracking or grinding noise when you move your knee.
- Your knee feels wobbly, as if it could buckle or give out.”
- Your knee might lock up, or feel as if it is stuck.
How Common Is Osteoarthritis
Women are more likely to develop osteoarthritis than men. Australian studies show that about 1 in 10 women report having the condition, compared with about 1 in 16 men.
Osteoarthritis can develop at any age, but it is more common in people aged over 40 years or in those who have previously injured a joint. One in 5 Australians over the age of 45, and one in 3 over 75 years have osteoarthritis.
Cracking Or Popping Sounds
When you bend or straighten your knee, you may feel a grinding sensation or hear cracking or popping sounds. Doctors call this crepitus.
These symptoms can occur when youve lost some of the cartilage that helps with smooth range of motion. Both OA and RA can result in cartilage damage.
When cartilage is damaged, rough surfaces and bone spurs develop. As you move your joints, these irregular areas rub against each other.

Causes And Risk Factors Of Osteoarthritis
At the ends of normal, healthy joints is cartilage a firm, rubbery material mostly made up of a matrix and two types of proteins .
Cartilage serves as a shock absorber that also allows bones to glide over each other when a joint bends or straightens. Thanks to its water content, cartilage can change shape to absorb impacts when it is compressed.
In people with osteoarthritis, the cartilage loses a lot of its water content and deteriorates, reducing its ability to absorb shocks.
Without this cartilage, the bones underneath can rub together, causing pain and inflammation at the joint. Cartilage can undergo some repair when damaged slowly, since it contains no blood vessels but the body does not produce new cartilage after injury.

Osteoarthritis Of The Knees
Like hip OA, knee OA can occur in one or both knees. Age, genetics, and knee injury may all play a role in knee OA.
Athletes who concentrate solely on one sport that involves extensive, repetitive motion, such as running or tennis, may be at increased risk of OA. Likewise, if you pursue only one type of physical activity, this may overuse some muscles and underuse others.
Overuse causes weakness and instability in the knee joint. Varying your activities helps to work different muscle groups, allowing all the muscles around your knee to be strengthened.
How Is Oa Treated
There is no cure for OA, so doctors usually treat OA symptoms with a combination of therapies, which may include the following:
- Increasing physical activity
- Medications, including over-the-counter pain relievers and prescription drugs
- Supportive devices such as crutches or canes
In addition to these treatments, people can gain confidence in managing their OA with self-management strategies. These strategies help reduce pain and disability so people with osteoarthritis can pursue the activities that are important to them. These five simple and effective arthritis management strategies can help.
Physical Activity for Arthritis
Some people are concerned that physical activity will make their arthritis worse, but joint-friendly physical activity can actually improve arthritis pain, function, and quality of life.

- Wear shoes with thick soles and enough room for your toes. Wearing the right shoes can reduce the shock through your knees as you walk and prevent any changes to your feet.
- If you need extra support for your feet or knees when you walk, speak to your physiotherapist, occupational therapist or doctor about getting insoles made for your shoes.
- Use a walking stick if needed to reduce the weight and stress on a painful knee. An occupational therapist can advise on the correct length and the best way to use the stick.
- Use a handrail for support when going up or down stairs. Go upstairs one at a time with your good leg first.
- Think about making changes to your home, car or workplace to reduce unnecessary strain. An occupational therapist can advise you on special equipment that will make things you do every day easier.

Once the severity of the condition has been accurately analyzed, the doctor will be able to recommend a suitable course of treatment. This will be undertaken with consideration given to the patients unique situation as everyone will have their own indicators and limitations regarding treatment.
It must be remembered that knee pain and other associated symptoms differ significantly from case to case. As such, patients who begin to suspect knee osteoarthritis should see a doctor in order to ensure screening and diagnosis takes place at the outset, which will enable appropriate subsequent treatment. However, if patients can take good care of their health, meaning they regulate their body weight, exercise regularly to strengthen the leg muscles, and avoid activities that place the knees under excess strain, they will be able to effectively reduce the likelihood of knee pain while also extending the lifespan of these crucial joints.

At first, you might only feel it first thing in the morning, or after you get up from sitting at your desk for a few hours. Over time, the ache may become more frequent. You might notice it when youre climbing stairs or if you kneel for too long. Some people even find the pain wakes them up at night, according to the Arthritis Foundation.

Osteoarthritis Vs Rheumatoid Arthritis: What Is The Difference
Osteoarthritis and RA affect the body differently.
In osteoarthritis, which is most often a mechanical disease, the cartilage that covers the ends of the bones in a joint is damaged by multiple different causes.
But in RA, the joint lining becomes inflamed and eventually erodes the joint.
This disease is considered an autoimmune condition because the immune system mistakes joint linings for foreign objects and attacks them, resulting in inflammation.
Additionally, unlike osteoarthritis, RA develops because of a combination of genetic and environmental factors, such as viruses, bacteria, and severely stressful events.
