What Can I Expect During The Procedure
Blood is removed from the arm using a needle into the vein. Then the blood is processed in a centrifuge, equipment that separates blood components into different parts according to their density. The platelets are separated into blood serum , while some of the white and red blood cells may be removed. Therefore, by spinning the blood, the equipment concentrates the platelets and produces what is called platelet-rich plasma .
However, depending on the protocol used to prepare PRP, there are multiple different products that can result from putting blood into the centrifuge. Therefore, different PRP preparations have different number on platelets, white blood cells, and red blood cells. For example, a product called platelet-poor plasma can be formed when most of the platelets are removed from the serum. The serum that is left contains cytokines, proteins and growth factors. Cytokines are emitted by immune system cells.
If the platelet cell membranes have been lysed, or destroyed, a product called platelet lysate , or human platelet lysate can be formed. PL often is made by freezing and thawing the plasma. PL has a higher number of some growth factors and cytokines than PPP.
Helping Patients To Make Informed Decisions
We’re funding research to improve patient experience before, during and after knee replacement surgery. This includes a project based at the University of Sheffield which aims to help patients make informed decisions about their surgery. The research team will use the UK National Joint Registry dataset to develop and validate a personalised, web-based decision aid to help patients considering knee joint replacement to make informed choices about their treatment.
How Is Knee Arthritis Diagnosed
Your doctor may use some of the following diagnostic tests and procedures to determine if you have knee arthritis:
- Medical history and physical examination
- Blood tests for genetic markers or RA antibodies
- X-rays to determine cartilage loss in the knee
- Joint aspiration: drawing out and testing the synovial fluid inside the knee joint
Cartilage cannot be seen on X-ray, but narrowing of the joint space between the bones indicates lost cartilage. X-rays show bone spurs and cysts, which can be caused by osteoarthritis. Other tests such as MRI or CT scans are rarely needed for diagnosis.

Should You Have Surgery For Arthritis In Your Knees
Posted on May 11, 2018
I was recently being diagnosed with a torn meniscus from playing football. Thus, Ive been looking up a lot of research on various knee surgeries lately.
I have a good base of knowledge but I find I tend to go through phases where a specific condition or joint tends to predominate in my life or in my clients. That leads me to see what new things I can learn related to that condition or joint.
While researching different forms of knee surgery I came across this AWESOME paper on arthroscopic surgery on the knee for people with osteoarthritis.
Without going into too much detail in this post, Ive always been skeptical of the majority of knee surgeries done on people. Specifically arthroscopic surgery for cleaning out the knee. This would consist of cleaning up the meniscus, bone spurs, etc. This is a big part of whats done in knee surgery for arthritis.
The first reason for this is there are a lot of people walking around with a beat-up meniscus who arent in any pain. This review paper cites a study showing that 59% of basketball players and endurance runners have a full thickness chondral defect in at least one of their knees, yet they arent in any pain!
In simpler terms: there are studies showing the majority of certain athletes arent in pain yet still have a full tear of their cartilage.
Furthermore, there are plenty of people who are in constant knee pain yet will have no abnormal findings, such as a meniscal tear, show up on a MRI.
When Knee Arthritis Requires Knee Replacement Surgery
Are you suffering from chronic knee pain? If you are, then you know how much this kind of pain can affect your quality of life. Knee pain can be caused by different things, but the most common cause of chronic pain is arthritis.
When knee pain is limiting the things that you can do, an orthopedic surgeon who specializes in the treatment of problems with bones, joints, tendons, ligaments, muscles, and cartilage can diagnose the cause of your pain and offer many different treatment options based on your individual needs. Depending on the severity of damage in your knee, treatments can range anywhere from exercise, soothing ointments, or mild over-the-counter medications to knee replacement surgery.
Your health history including what treatments have worked or failed for you in the past, your X-rays, and your physical exam results will all give your doctor valuable insight into what options might work for you. If you have tried a number of therapies and are still bothered significantly by knee pain, your knee arthritis may be severe enough to require knee replacement surgery.

Getting Into And Riding In A Car
When getting into a car:
- Get into the car from street level, not from a curb or doorstep. Have the front seat moved back as far as possible.
- Car seats shouldn’t be too low. Sit on a pillow if you need to. Before you get into a car, make sure you can slide easily on the seat material.
- Turn around so the back of your knee is touching the seat and sit down. As you turn, have someone help lift your legs into the car.
When riding in a car:
- Break up long car rides. Stop, get out, and walk around every 45 to 60 minutes.
- Do some of the simple exercises, like ankle pumps, while riding in the car. This helps reduce the risks of blood clots.
- Take pain medicines before your first ride home.
When getting out of the car:
- Turn your body as someone helps you lift your legs out of the car.
- Scoot and lean forward.
- Standing on both legs, use your crutches or walker to help you stand up.
Ask your health care provider when you can drive. You may need to wait up to 4 weeks after surgery. Do not drive until your provider says it is OK.
Arthritis Of The Knee
is a condition in which there is loss of the articular cartilage of the femur, tibia, or patella. This can be seen on X-ray as a loss of the space between the two ends of bone.
X-ray of an Arthritic Knee
Because of the loss of the gliding surfaces of the bone, people with arthritis may feel as though their knee is stiff and their motion is limited. Sometimes people actually feel a catching or clicking within the knee. Generally, loading the knee joint with activities such as walking long distances, standing for long periods of time, or climbing stairs makes arthritis pain worse. When the arthritis has gotten to be severe, the pain may occur even when sitting or lying down. The pain is usually felt in the inside part of the knee, but also may be felt in the front or back of the knee. As the cartilage is worn away preferentially on one side of the knee joint, people may find their knee will become more knock-kneed or bowlegged.

Cartilage Repair And Cartilage Restoration
One way to stimulate cartilage growth is by making precise microfractures in the surrounding bone. This procedure is called bone marrow stimulation.
Once damaged, cartilage does not heal well. Even if the joint is able to grow new cartilage, it tends to be rough and bumpy and therefore less able to facilitate smooth movement at the joint. There are a handful of surgeries that attempt to repair or encourage the growth of healthy cartilage:
- Bone marrow stimulation, which stimulates cartilage growth by making precise microfractures in the surrounding bone
- Osteochondral transplantation techniques , also referred to as mosaicplasty, which involves transplanting cartilage from one site to another
- Autologous chondrocyte implantation , which requires two surgeries. In the first, cartilage cells are harvested and then grown in a laboratory for several weeks. During the second surgery the cartilage cells are re-implanted.
These procedures may be appropriate for patients who have a relatively small and very isolated area of articular cartilage damage. Typically, these patients are younger and have damaged their cartilage through trauma rather than over years of gradual wear and tear. Therefore, these surgeries are usually more appropriate for people trying to slow or prevent severe arthritis rather than alleviate it.

Reasons For The Procedure
Knee replacement surgery is a treatment for pain and disability in theknee. The most common condition that results in the need for kneereplacement surgery is osteoarthritis.
Osteoarthritis is characterized by the breakdown of joint cartilage.Damage to the cartilage and bones limits movement and may cause pain.People with severe degenerative joint disease may be unable to donormal activities that involve bending at the knee, such as walking orclimbing stairs, because they are painful. The knee may swell orâgive-wayâ because the joint is not stable.
Other forms of arthritis, such as rheumatoid arthritis and arthritis thatresults from a knee injury, may also lead to degeneration of the kneejoint. In addition, fractures, torn cartilage, and/or torn ligaments maylead to irreversible damage to the knee joint.
If medical treatments are not satisfactory, knee replacement surgery may bean effective treatment. Some medical treatments for degenerative jointdisease may include, but are not limited to, the following:

How To Use Pain Medications Properly
There are two types of over-the-counter pain medications that can be used for osteoarthritis. Acetaminophen is a pain reliever but not an anti-inflammatory. It may help with mild knee pain.
NSAIDs can be more effective because they both relieve pain and reduce inflammation. However, they come with potential side effects and risks. NSAIDs can irritate the lining of the stomach, which may lead to an ulcer or other stomach problems. They also can impair kidney function. Some NSAIDs can increase blood pressure. And theyve been linked to an increased risk for heart disease.
Because of the risks, Dr. Day cautions against using NSAIDs regularly over long periods of time. Instead, she uses NSAIDs for her patients in two ways. First, people who have a flare-up of pain can take them regularly for three to five days and then stop. Second, they can be used over the long term, but only occasionally, maybe a couple of times a week as needed.
If youre taking NSAIDs several times a day for long periods of time, Dr. Day advises reducing their use by maximizing the other treatment strategies. She also suggests trying a topical NSAID, such as diclofenac , which has fewer potential side effects.
Opioid pain relievers are discouraged for long-term treatment of chronic knee pain. The milder narcotic tramadol might be appropriate for occasional use in some people, says Dr. Day.

Can Rehabilitation Be Done At Home
All patients are given a set of home exercises to do between supervised physical therapy sessions and the home exercises make up an important part of the recovery process. However, supervised therapywhich is best done in an outpatient physical therapy studiois extremely helpful and those patients who are able to attend outpatient therapy are encouraged to do so.
For patients who are unable to attend outpatient physical therapy, home physical therapy is arranged.

Surgery Is One Option
The loss of hand function is a serious matter, especially when the hands are also painful. When other therapy has not helped enough to allow you to do necessary tasks, such as holding a fork or zipping clothing, surgery may be the answer. In addition, some people with arthritis are concerned about deformity in their hands. While surgery may improve the look of the hands, remember that the main purposes of surgery are to decrease severe pain and to restore function.
Can Arthritis Be Removed Surgically By Scraping
Arthritis is not something you can put your finger on. Arthritis is the name of over one hundred different conditions that usually cause damage to joints of the body and less often other organs of the body. The result of arthritis is usual cartilage damage which can lead to further problems with unwanted bone growth in joints ligament and muscular destruction. some work is done to try to scrape unwanted bone and tissue out of joints. however the most effective method is to remove the damaged parts in a joint altogether and replace them with prosthesis.

Make Sure You Get Enough Vitamin C
Vitamin C not only helps produce collagen, a major component of joints, but sweeps the body of destructive free radicals, which are harmful to joints. One of the best-known studies looking into vitamin C and arthritis found that people whose diets routinely included high amounts of vitamin C had significantly less risk of their arthritis progressing. Spread out your intake throughout the day because your body doesnt store vitamin C rather, it takes what it needs from the bloodstream at any given time and flushes out the rest. This means a megadose in the morning doesnt really do as much good. Sip citrus drinks or eat C-rich fruits and vegetables such as strawberries or melon, broccoli, or sweet peppers. And be sure to avoid these foods that might flare your arthritis.
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.
