How Is Cartilage Damage In The Knee Diagnosed
Cartilage damage as a result of a forceful injury is often accompanied by other injuries particularly if you have wrenched or even a dislocated your knee, so its not always obvious what is causing your knee pain.
Even if you have cartilage damage due to wear and tear, the symptoms can be similar to many other knee conditions so its always best to get seen by a knee specialist.
The Capital Orthopaedics team is highly experienced at diagnosing knee conditions, starting with a history of your lifestyle or injury and a physical/biomechanical exam.
You will then be given x-ray or CT scans to assess damage to the bones in your joint, and an MRI to review cartilage damage and any other soft tissue injuries.

Making Knees New Again
How are your knees? If youre like many people age 50 and older, theyve been aching. If youre 65 or older, you may have some degree of osteoarthritis, in which the cartilage that cushions the ends of the bones in the joints begins to degenerate or wear away.
Symptoms can range from stiffness to severe pain and limited mobility. So its probably not surprising that surgeons perform more than 700,000 knee-replacement surgeries in the United States each year.
Total knee replacement is very effective, but implants dont last forever. Although they can last 20 years, one study found that about 14.9 percent of men and 17.4 percent of women who receive a total knee replacement will need another. The earlier you get your implant, the more likely youll be back in surgery at some point.
Thats why knee replacement should only be considered after youve tried everything else, says Harpal S. Khanuja, M.D., chief of hip and knee replacement surgery with the Department of Orthopaedic Surgery at Johns Hopkins. That includes following your doctors recommendations for losing weight, physical therapy, pain management, and modifying your activities.
I tell people its time for a replacement when they cant live the life they want to live it is not a good solution for an occasional pain, Khanuja says.
To keep knee replacement as a last resort, keep your knees healthy with these smart steps.

Measuring Brain Stem Responses Could Help To Diagnose Tinnitus
A new diagnostic tool for tinnitus might finally be on the horizon following study results published in the Journal of Clinical Investigation.
The condition typically causes a ringing or buzzing noise in the ear without any obvious source, but there is no test to confirm diagnosis.
Now researchers at Karolinska Institute in Sweden have discovered that measuring auditory brainstem responses which examine the brains response to sound stimuli can distinguish patients with tinnitus from those without.
Its thought that alterations in brain activity, as a result of initial noise exposure damaging hearing cells in the ear, could be a sign of the condition and that ABR measurements may reflect this.
What Are Glucosamine Sulfate And Chondroitin Sulfate
Glucosamine sulfate and chondroitin sulfate are components of normal cartilage. These nutritional supplements are available in pharmacies and health food stores without a prescription. They are the building blocks for proteoglycans and appear to stimulate chondrocytes to make new collagen and proteoglycans. The supplements are well-tolerated and safe.
Because these supplements stimulate the production of new cartilage components, it is thought that they may be able to help the body repair cartilage damaged by osteoarthritis. However, much of the research on glucosamine sulfate and chondroitin sulfate has been done in vitro and in animals. To date, there has not been any convincing proof in humans that glucosamine and chondroitin sulfates can help rebuild cartilage or prevent damage to cartilage.

Ways To Care For Your Cartilage
Losing your joint cartilage ages you fast. It takes away your independence and leaves you in constant, awful pain. Here are 5 ways to make sure your joints stay supple and pain-free.
1. Elastin: Its a protein found in connective tissue that works alongside collagen. Like the name suggests, it allows your tissue to stretch. Not having enough causes wrinkles to form on your face. But itll also weaken the cartilage in your joints, robbing you of your mobility.1
To stay loose and pain-free, your best bet is to find foods that support the elastin in your body. Vitamin C is essential. Foods like red bell pepper, broccoli, kiwi, and kale are great sources. They have more vitamin C per serving than an orange.
2. Astaxanthin: The cartilage in your knee joints is just as prone to damage from free radicals as your eyes and skin.2 A powerful antioxidant will help keep it protected. And astaxanthin is 60 times stronger than vitamin C when it comes to fighting oxidative stress.
Astaxanthin can be found naturally in cold water fish like salmon. A six ounce serving will give you about four milligrams. You can find the same amount in supplement form too. And if youre already taking krill oil, youre getting some astaxanthin in each serving.
You can get more of this vitamin simply by spending more time in the sun. You can also add more of it to your diet by eating eggs, mushrooms, and wild-caught salmon. If youre going to take a supplement, make sure it comes from a natural food source.
Surgery For No Cartilage In Knee: What Are The Options
Firstly, keyhole surgery for knee osteoarthritis is not effective and, in fact, could accelerate knee damage.
High tibial knee osteotomy can reduce pressure on the knee joint if there is a malalignment problem. However, evidence for effectiveness is not strong and risks are real.
Finally, knee replacement surgery is effective at reducing pain and improving function compared to physiotherapy, but the sting in the tail is that 16% of people have problems after this surgery some of these are serious. Bottom line is that surgery should only be done once your pain and activity levels become unacceptable.

How Yoghurt Can Make Berries Even Healthier
Eating blueberries with yoghurt may improve your intake of the nutrients they provide, suggests the Journal of Agricultural and Food Chemistry.
In research with rats, alpha-casein was added to anthocyanin the next day the rodents had higher concentrations of anthocyanin in their blood.
The researchers said the milk protein molecule wraps around the antioxidant, stopping it disintegrating as it moves through the intestine and bloodstream.
They will now see if the protein has the same effect in the human digestive system.
Ten minutes of exercise is enough to boost mood, say researchers at Tsukuba University in Japan. They asked 26 adults to perform mental tasks before and after running on a treadmill for ten minutes.
After the run, tasks took less time and the participants mood improved, possibly as physical activity affects the pre-frontal cortex, the brain area involved in emotion, said the researchers.
Mayo Clinic Q And A: New Technique For Repairing Knee Cartilage Damage
DEAR MAYO CLINIC: I’m interested in the new procedure approved by the U.S. Food and Drug Administration that can repair cartilage in the knee. How does it work? Who’s a good candidate for this procedure?
ANSWER: The new technique is called matrix-associated autologous chondrocyte implantation, or MACI. It can be effective for repairing isolated cartilage damage in the knee, but it’s not useful for people whose knee cartilage is diffusely damaged due to arthritis.
Your knee has two kinds of cartilage: the articular cartilage and the meniscus. Matrix-associated autologous chondrocyte implantation is used to repair articular cartilage damage, which can come from an isolated injury or defect, or as a result of arthritis.
Of these two problems, isolated injuries and defects are much less common than arthritis. They usually happen due to an athletic injury or another medical condition, such as osteochondritis dissecans. Both isolated cartilage defects and arthritis have similar symptoms, including knee pain, swelling and loss of motion.
With matrix-associated autologous chondrocyte implantation, the new cells are grown on a membrane scaffold in the lab. That’s different than the cartilage repair techniques previously used. In the older approaches, cartilage cells were grown in a lab and implanted into the knee under a patch created from a membrane taken off the outer surface of a bone, called the periosteum, or implanted under a membrane made of collagen.

New Procedure Helps Patients Regrow Cartilage In Their Knee
Locking. Swelling. Pain. Clicking. When you feel any of these in your knee, its a sign the cartilage in your knee may be eroding. If treatments like rest, medication or physical therapy dont work, you may benefit from a newer surgical procedure that helps people regrow their knee cartilage.
Orthopedic surgeon Peter Wang Jr., MD, with Upper Bucks Orthopaedics at Grand View Health is skilled in a technique called MACI. It transplants your bodys own cartilage-forming cells into your knee to help regrow damaged cartilage, relieve pain and increase range of motion.
MACI stands for matrix-induced autologous chondrocyte implantation. Its a modern enhancement to ACI surgery, which orthopaedic surgeons have performed for more than 20 years.
Clinical trials show MACI offers less pain and better range of motion for patients compared to microfracture surgery, which requires drilling into the bone Wang said.
How MACI at Grand View Health Works
The MACI procedure works in three stages. First, patients undergo a biopsy that extracts cartilage-forming cells, called chondrocytes, from the body. Next, medical team members send your cells to a lab, where theyre embedded onto a collagen membrane and multiply.
Then at Grand View Health, on the day of surgery, a surgeon implants the collagen membrane into your knee. As you recover from surgery, the cartilage cells regenerate, forming new tissue to replace worn-out cartilage.

What Are The Stages Of Arthritis Of The Knee
There are five stages of osteoarthritis, the most common type of arthritis that affects your knees:
- Stage 0 . If youre at stage 0, your knees are healthy. You dont have arthritis of the knee.
- Stage 1 . Stage 1 means that youve got some wear and tear in your knee joint. You probably wont notice pain.
- Stage 2 . The mild stage is when you might start to feel pain and stiffness, but theres still enough cartilage to keep the bones from actually touching.
- Stage 3 . If youre at the moderate stage, youll have more pain, especially when running, walking, squatting, and kneeling. Youll likely notice it after long periods of rest . You’re probably in a great deal of pain because the cartilage has narrowed even further and there are many bone spurs.
- Stage 4 . Severe osteoarthritis means that the cartilage is almost gone. Your knee is stiff, painful and possibly immobile. You might need surgery.

Your knee is the largest joint in your body, and it takes a massive force every step you take. 346% of your body weight goes through your knee when youre walking downstairs. Running can put 11 times your body weight through your knee joint. And the heavier you are, the greater the force.
Our knees have to be pretty extraordinary structures to be able to cope with this enormous strain.
As in all joints, the bones are coated in a layer of slippery cartilage which enables smooth, friction-free movement. In the middle of your knee are two rubbery, semi-circular pieces of cartilage called menisci, which provide additional shock absorption.
Small fluid-filled sacs called bursa also help with cushioning as you pound away at your knee joints.
Just as in any mechanical structure, repeated force or a sudden impact will cause the parts of your knee joint to get worn, torn or damaged.
The result is a pain in your knees. It may be a dull ache, or sharp, debilitating pain. It may be accompanied by swelling and a feeling of instability. It may change your life
No matter what the best thing you can do is get a diagnosis, and the sooner the better. Joints that take that much force on a daily basis rarely get better on their own. Many knee conditions can be resolved with physiotherapy if they are caught soon enough. Even if you need surgery, the sooner you can get treated, the less likely you are to have ongoing repercussions such as osteoarthritis.

Knees Hurt Options For Cartilage
Knee pain can be caused by damaged cartilage. A Michigan Medicine orthopaedic surgeon describes the current surgical remedies, including a new procedure being tested here.
Oh, your aching knees. People of all ages and all levels of physical activity experience knee pain. When pain is widespread and diffuse in one or both knees, the problem is often arthritis. But when the problem comes from one place in one knee, with concentrated pain, swelling that doesnt go away, or a sense that the knee is clicking when it is moved back and forth, injured cartilage may be the culprit.
We asked John A. Grant, Ph.D., M.D., F.R.C.S.C., Dip. Sports Med., to provide an overview of cartilage-related knee pain and what can be done about it. Grant is an orthopaedic surgeon at Michigan Medicines MedSport, who has a focus in knee cartilage treatment and research.
What Are The Types Of Arthritis Of The Knee
There are around 100 types of arthritis. The most common types that might affect your knees include:
- Osteoarthritis is the most common of the types on this list. Osteoarthritis wears away your cartilage the cushioning between the three bones of your knee joint. Without that protection, your bones rub against each other. This can cause pain, stiffness and limited movement. It can also lead to the development of bone spurs. Osteoarthritis gets worse as time passes.
- Post-traumatic arthritis is a type of osteoarthritis. The cartilage starts thinning after trauma to your knee . Your bones rub together, and that causes the same symptoms as osteoarthritis: pain, stiffness and limited movement. Your knee arthritis symptoms might not start until years after the trauma.
- Rheumatoid arthritis is an autoimmune disease. A healthy immune system causes inflammation when it’s trying to protect you from an infection, injury, toxin or another foreign invader. The inflammatory response is one way your body protects itself. If you have rheumatoid arthritis, you have an unhealthy immune system that triggers inflammation in your joints even though theres no foreign invader. The inflammation causes pain, stiffness and swelling of the synovial membrane, which can also wear away your cartilage.

Use Targeted Exercises To Build Muscle
Moderate exercise is an excellent way to help protect your knee joints. Building up the muscles around your knees helps reduce the stress on your joints. Your outer, middle, and inner thigh muscles and calf muscles help support your knees.
Your local gym may offer senior exercise classes with instructors who have been specially trained to work with men and women over 50. Water aerobics is also a great way to get non-weight bearing exercise. If youd rather work out by yourself, check in with a trainer whos knowledgeable about senior exercise needs.
At your next physical, ask your doctor to check your leg strength. If youre weak, physical therapy can help strengthen your muscles, and the therapist can show you beneficial exercises for your knees.
Inflammation And Your Knees
Knee injuries cause inflammation, which in turn causes pain. Chronic knee pain might be due to several conditions that also cause inflammation directly or indirectly. These conditions may include arthritis, gout, tendonitis, bursitis, and several other itis conditions.
So, by eating the best foods that reduce inflammation, you more or less help your knees stay healthy and pain-free!
