How Is Knee Injection Performed
Knee injection is a relatively quick procedure and may be performed under local anesthesia to avoid pain. A needle of appropriate size and length connected to a syringe is introduced into the joint and the medication is injected. Radiological guidance may sometimes be used to aid injection.
After the procedure, the patient would need to rest for a few minutes, and then they can resume normal activities. Patients may experience pain, swelling, and bruising, which resolve in a few days. Ice packs and pain killers can help reduce pain and bruising.
Osteoarthritis Of The Hips
OA can occur in one or both hips. In this way, it differs from RA, which usually occurs in both hips at the same time.
Hip OA is a slowly degenerative condition. Many people find that theyre able to manage their symptoms for many years by using medications, exercise, and physical therapy. Supports, such as canes, can also help.
Deformities Of The Knee
The appearance of the knee can change during a flare and as damage progresses.
In RA, swelling and redness are common during a flare. In the long term, persistent inflammation can result in permanent damage to the cartilage and the tendons. This can affect the shape and appearance of the knee.
With OA, the muscles around the knee can weaken, resulting in a sunken appearance. The knees can start to point toward each other or bend outward.
Knee deformities range from barely noticeable to severe and debilitating.
Treatment will depend on the type of arthritis a person has.

What Is Knee Arthritis
Knee arthritis is inflammation and deterioration of knee joint cartilage. Cartilage is the slippery coating on the ends of bones that serves as a cushion and allows the knee to smoothly bend and straighten. Knee cartilage coats the end of the thighbone , top of the shinbone and the backside of the kneecap . When cartilage wears away, the space between the bones narrows. In advanced arthritis, bone rubs on bone and bone spurs may form.
Damage to the joint cartilage over time may result in the development or worsening of deformities of the knee, including knock knees and bowleg.
Rheumatoid Arthritis And Kidney Function: What To Know
Amyloidosis, a condition caused by the abnormal buildup of certain proteins that can impair kidney function, may occur in association with RA usually in the later stages or if someones disease isnt well-controlled with medication. The symptoms can be vague, such as weakness or swelling, and can include an enlarged spleen and gastrointestinal issues.
To screen for amyloidosis, rheumatologists will periodically check your kidney function.
To maintain healthy kidneys, you should also take care not to overuse nonsteroidal anti-inflammatory painkillers , like ibuprofen and naproxen, as they can damage the kidneys, too.

How Is Knee Arthritis Treated Nonsurgically
The severity of your arthritis will determine the most appropriate course of action. For early-stage arthritis, effective treatments include:
- Physical therapy
In more advanced cases, the following can be effective at relieving your symptoms:
Activity modification
Patients with arthritis typically have to undergo some lifestyle modifications. If specific activities make your symptoms worse, then avoiding those activities can provide relief. Low-impact exercises such as cycling, elliptical, swimming, and light strength training are the best options.
Anti-Inflammatory medication
Oral anti-inflammatory medicines may be effective at decreasing inflammation associated with osteoarthritis. However, some people suffer from side effects while taking them. If you experience anything unusual when taking these medications, contact your doctor immediately to determine if continued use is appropriate.
Unloader knee braces
Your doctor may prescribe an unloader brace. This brace relieves the pressure on the worn area of the joint. You will need to wear this brace when participating in such activities as walking, hiking, and sports. For some, this brace may provide significant symptomatic relief, allowing the enjoyment of physical activity again.
Steroid injections
There is no limit to the total number of knee injections you can have, and long-term steroid injection treatment does not cause any further damage to the joint.
Physical therapy
Joint fluid therapy
Ice
Are There Any Complications
Osteoarthritis can develop over just a year or two, but more often its a slow process over many years that only causes fairly small changes in just part of the knee.
But in some cases, the cartilage can become so thin that it no longer covers the ends of the bones. This causes them to rub against each other and eventually wear away.
The loss of cartilage, the wearing of the bones, and the bony spurs can change the shape of the joint. This forces the bones out of their normal positions, making your knee feel unstable and painful.
Some people with osteoarthritis find a lump appears at the back of their knee. This is called a Bakers cyst or popliteal cyst.
A Bakers cyst is fluid-filled swelling at the back of the knee that happens when part of the joint lining bulges through a small tear in the joint capsule. This can then cause joint fluid to be trapped in the bulge.
It can happen on its own, but is more likely in a knee thats already affected by arthritis. A Bakers cyst doesnt always cause pain, but sometimes they can burst so the fluid leaks down into your calf, causing sharp pain, swelling and redness in the calf.
Osteoarthritis in the knee might change the way you walk or carry your weight, and this could cause you to develop the condition in other joints, such as your hips.

What Are The Benefits Of Knee Arthroscopy
Knee arthroscopy is an effective tool in diagnosing your joint condition and for confirming treatment for knee problems such as meniscus tears and cartilage wear. An arthroscopy can ultimately provide relief from knee pain and improve mobility. Maintaining a normal and active lifestyle with greater comfort is a key benefit of this procedure.
Complementary Medicines Or Alternative Therapies
Complementary and alternative treatments are widely used by people with musculoskeletal conditions, including osteoarthritis of the knee.
Transcutaneous electrical nerve stimulation A TENS machine is a small battery powered device with leads that connect to sticky pads on your body. It delivers very small electrical currents to your skin that stimulate nerves to relieve pain. Some people find it helpful in relieving pain while others do not. The quality of evidence showing it helps with knee OA is very low. If youre thinking of using a TENs machine speak with your doctor to see if its a suitable option for you. You can often hire one from your physiotherapist, local pharmacy or local hospital.
ElectrotherapyElectrotherapy treatments are thought to minimise inflammation, promote cell growth and modify pain. While some trials have shown short-term benefits with electrotherapy, the evidence for its use in knee OA is low to very low. For this reason its not generally recommended.
AcupunctureThe use of traditional , laser and/or electro acupuncture for knee OA is not supported by current clinical evidence. While some improvements in knee pain and function have been identified in low-quality studies, the benefits are considered so small that theyre not clinically relevant. Also to see any benefits from treatment, its likely that you will need multiple sessions of acupuncture which could become quite costly.

What Are Knee Arthritis Symptoms
As the disease develops, more of the articular cartilage breaks down. Ultimately, this will allow the bones to rub against one another. At this point, the pain in the knee will become very severe. The pain may be so intense at times that it will prevent you from sleeping at night.
Eventually, as the disease progresses, the bones in the knee can be forced out of their normal position. This can lead to a deformity of the knee. However, these changes will happen very slowly so you may not notice the change in the knee until at an advanced stage.
Other symptoms of knee arthritis include:
What You Need To Know
- Knee arthritis occurs when the cushioning cartilage in the joint wears down, making the knee stiff and painful with certain movements.
- Osteoarthritis gradual, age-related degeneration of cartilage is the most common form of arthritis in the knee, but trauma and autoimmune conditions can also lead to cartilage damage.
- The cartilage damage associated with arthritis is irreversible, but there are nonsurgical and surgical treatments that can help reduce pain, increase joint flexibility and improve overall quality of life for people with knee arthritis.

How Is Osteoarthritis Managed
There is no cure for osteoarthritis, but most people with osteoarthritis can manage their symptoms, continue with daily activities and live healthy and enjoyable lives. Be careful of any products or treatments that claim to cure osteoarthritis completely your doctor will help to find the right treatment for you.
The Australian Commission on Safety and Quality in Health Care has developed a guide to help you discuss the main treatment options for osteoarthritis of the knee with your doctor.
How Is Osteoarthritis Diagnosed
There is no specific test for osteoarthritis. Your doctor will confirm or rule out osteoarthritis based on your symptoms and a physical examination. Some signs they may look for are:
- swelling around the joints in your body
- damage to joint cartilage cartilage is the smooth, cushion-like surface that covers the ends of your bones to allow them to move smoothly
- spurs extra bone growing around the edge of a joint
- weakness in the ligaments and tendons the connective tissue that holds your joints together or attaches muscles to bones
Your doctor may refer you for an x-ray to look for narrowing and changes in the shape of your joints. A blood test may help to rule out other types of arthritis .

Jak Inhibitors And Ra
- Tofacitinib is the first in a new class of small molecule medications used to treat rheumatoid arthritis called JAK inhibitors. Tofacitinib is a treatment for adults with moderate to severe active RA in which methotrexate was not very effective. Patients can take tofacitinib with or without methotrexate, and this prescription drug is taken by mouth two times a day. Tofacitinib is a targeted drug that only blocks Janus kinase, special enzymes of inflammation, within cells. This is why it is referred to as a JAK inhibitor. JAK inhibitors are not used with biologic medications.

What Is Arthritis
Painful joint swelling is called arthritis. Osteoarthritis is due to wear and tear of the joints over many years. Arthritis maye develop in any joint, including the fingers, hips and knees. Usually, patients with arthritis feel pain in their joints even after moderate movements. The cartilage breaks down over time, leaving the bones without cushions. This causes the bones to rub against each other resulting in painful swelling. Arthritis is a very painful condition that does not have a cure. However, there are lots of treatment options available to curb the complications of arthritis.

Who Is At Risk
Chondrosis of the knee is often associated with certain types of exercise or obesity. Every pound of weight on the upper body places four pounds of force on the knee joint.
Endurance athletes who run long distances are prone to joint pain. Fast-paced sports that require quick and dynamic movements are also hard on the knees.
Although high-impact exercise increases the risk of osteoarthritis, a sedentary lifestyle can also be a risk factor for chondrosis. Insufficient muscle tone fails to support the joints, placing them under added stress.
Osteoarthritis is common in people over age 50. Age is a leading cause of cartilage breakdown over time. Genetics also plays a role, especially when triggered by inflammation. Our bone structure can influence the likelihood of chondrosis, as is the case for individuals with naturally shallow hip sockets .
Performing a repetitive motion over the course of several years leads to overuse of the joint and can wear away the cartilage. Damage to cartilage may also occur during an injury or surgery and go unnoticed until osteoarthritis later develops.
Rheumatoid Arthritis In The Knee: Symptoms And Treatments
More than 1.3 million people in the U.S. have rheumatoid arthritis , which typically starts in the hands and fingers and can later progress to the knees. The resulting joint stiffness, pain, and swelling affecting the knees can restrict movement, potentially impacting quality of life.
To learn more about knee RA, myRAteam spoke with rheumatologist Dr. Iris Navarro-Millán, assistant professor of medicine at Weill Cornell Medicine and the Hospital for Special Surgery in New York City, and a National Institutes of Health -funded rheumatology researcher specializing in knee RA.
Because knee RA shares some symptoms with knee osteoarthritis , another form of arthritis, making a diagnosis can be challenging, Dr. Navarro-Millán said. When people with RA start experiencing knee pain, we tend to jump quickly to say, You probably also have osteoarthritis. But itâs very common for with RA to have both.
Many members of myRAteam report late-stage knee pain. Ive had RA for 10 years, but only experienced pain in my knees in the last one or two years, explained one member.
Getting a correct diagnosis, however, has been frustrating for some. My doctor said I dont have RA because its in my knees, yet everything Iâve read said that RA can attack the knees, one member said. Another member added, My rheumatologist was way too quick to assume my knee pain was fibromyalgia and OA, not RA. Im getting a second opinion.

Reducing The Strain On Your Knees
Apart from keeping an eye on your weight, there are a number of other ways you can reduce the strain on your knees.
- Pace your activities dont tackle all your physical jobs at once. Break the harder jobs up into chunks and do something gentler in between. Keep using your knee even if its slightly uncomfortable, but rest it before it becomes too painful.
- 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.
Using a heat pack or something similar on a painful knee might help to relieve the pain and stiffness of osteoarthritis. An ice pack can also help but be careful not to put ice or heat packs or hot water bottles directly on your skin wrap them with a tea towel or cover.
Gradual Increase In Pain
Arthritis pain usually starts slowly, although it can appear suddenly in some cases.
At first, you may notice pain in the morning or after youve been inactive for a while.
Your knees may hurt when you:
- climb stairs
- stand up from a sitting position
- walk on a flat surface
- sit down for a while
Knee pain that wakes you up from sleep can be a symptom of OA.
For people with RA, the symptoms often start in the smaller joints. They are also more likely to be symmetrical, affecting both sides of the body. The joint may be warm and red.
With OA, symptoms may progress rapidly or they may develop over several years, depending on the individual. Symptoms can worsen and then remain stable for a long time, and they can vary day to day.
Factors that may cause worsening of symptoms include:
- cold weather
- stress
- excessive activity
With RA, symptoms usually appear over several weeks, but they can develop or worsen in a few days. A flare can happen when disease activity increases. Triggers vary and can include changes in medication.

What Are The Risks Of Knee Arthroscopy
While knee arthroscopy is a safe procedure for the treatment of knee injuries, there are some risks that patients should be aware of. Depending on the patient and joint condition, these risks may include swelling and stiffness of the joint, bleeding, blood clots, infection, or continuing knee problems.
Osteoarthritis Vs Rheumatoid Arthritis
OA and rheumatoid arthritis share the same symptoms but are very different conditions. OA is a degenerative condition, which means that it increases in severity over time. RA, on the other hand, is an autoimmune disorder.
People with RA have immune systems that mistake the soft lining around joints for a threat to the body, causing the body to attack that area. This soft lining, which includes the synovial fluid, is called the synovium. As the immune system launches its assault, fluid buildup within the joint occurs. This causes stiffness, pain, swelling, and inflammation.
If youre not sure which form of arthritis you have, your best bet is to talk with your doctor. You can also do your own preliminary research. Take a closer look at the differences between RA and OA.
