Types Of Knee Cartilage Tears
What part of your knee cartilage have you injured? The two most common types of knee cartilage injury are:
- Articular cartilage tears, affecting the cartilage covering the ends of your bones at the knee joint. An injury to this cartilage is called a chondral injury. Chondral injury is commonly seen in cyclists, runners, skiers, and soccer players.
- Meniscus tears, affecting the c-shaped shock absorbers located on either side of your knee joint. Meniscus tears can happen to anyone at any age, but are particularly common in athletes who play contact sports like hockey or football.
Ligament injuries of the knee, such as ACL tears and PCL tears, are frequently confused with cartilage injuries. Though these are also components of the knee and share similar symptoms to cartilage tears, they’re different and may be treated differently.
How Does It Work
While were not exactly sure, researchers believe that fiber helps protect your knees in a couple of ways.
First, it reduces the levels of C-reactive protein, a protein that has been repeatedly correlated with inflammation. Second, fiber increases satiety, which makes you feel fuller and therefore prevents you from overeating.

Studies On Damaged Cartilage Regeneration
A study done by the University of Maryland Medical Center concluded that lysine deficiency can delay the growth of damaged cartilage. It can also affect the regeneration of skin cells, which damages the total reconstruction of the area involved with the physical damage.
12 mg of lysine for every kilo of body weight is what you should consume in order to help the body be able to rebuild cartilage faster. The foods that contain high levels of lysine are:

How Is Damaged Cartilage Regenerated
Cartilage is regenerated according to what food you eat. One of the other most common conditions that affects the ankle, knee, wrist, elbow, and shoulder cartilage is arthritis, currently a very well-known disease that affects almost everyone older than forty.
For this reason, it is necessary to have proper nutrition so that cartilage tissue can regenerate quickly.
One of the most important amino acids for the rapid regeneration of damaged cartilage is lysine. It is responsible for absorbing calcium and producing collagen that rebuilds damaged tissue. It also improves appearance of your skin and strength of your tendons.

Stages Of Cartilage Damage
- Stages I and II of cartilage damage are early stages. Once cartilage gets damaged, in its place fibrous cartilage is formed which has very poor mechanical strength.
- Presence of fibrous cartilage makes the joint susceptible to further injuries and it becomes very difficult to carry out normal activities like walking, running, yoga and sports. Reduced physical activity will lead to diseases associated with sedentary lifestyle such as diabetes, obesity, hypertension and cardiovascular disorders.
- A stage IV arthritic joint needs to be replaced by Total Knee Replacement Surgery.

Diseases That Affect The Cartilage
Osteoarthritis results in the cartilage which covers the bone, , slowly thins and wears away. This results in a bone upon bone situation which can be extremely painful and reduces the ability to move. Osteoarthritis can often be the result of high stress to a joint due to a specific activity. Traditionally, osteoarthritis eventually is treated by surgery and the introduction of implants . Replacement joints are never as strong as natural ones.
A detached or ruptured knee can result when the knee is either detached, or the disc in between the two bones is ruptured causing a leakage of the lubricating synovial fluid and resulting in a bone on bone situation, which is extremely painful and adversely affects the ability to move.
Bursitis occurs when the pouches or sacs of synovial fluid, surrounding the knee, elbow or shoulder joint become inflamed. This is sometimes referred to as housemaids knee, and tennis elbow.
Torn cartilage occurs when the meniscus, , can also be damaged. The meniscus on the outside of the knee is the lateral meniscus, the meniscus on the inside of the knee is medial meniscus.
Costochondritis is the inflammation of cartilage in the ribs which can cause chest pain .
How To Build Knee Cartilage Naturally
Cartilage is a flexible connective tissue, usually found coating joints, that helps reduce friction and protect the ends of the bone. This is found in the knee and elbow joints, as well as the tip of your nose. This material can be damaged as a result of vigorous activity, or it can simply wear as we age. However, different ways can help rebuild or improve your knee cartilage.
Nutritionists always recommend employing natural treatment methods to help inbuilding cartilage, and these methods often include ingesting collagen to heal your cartilage. This is the safest method that can help you avoid knee replacement surgery. Medical treatment may not be necessary if you take good care of your health.

Researchers Find Method To Regrow Cartilage In The Joints
In laboratory studies, Stanford School of Medicine researchers have found a way to regenerate the cartilage that eases movement between bones.
Researchers at the Stanford University School of Medicine have discovered a way to regenerate, in mice and human tissue, the cushion of cartilage found in joints.
Loss of this slippery and shock-absorbing tissue layer, called articular cartilage, is responsible for many cases of joint pain and arthritis, which afflicts more than 55 million Americans. Nearly 1 in 4 adult Americans suffer from arthritis, and far more are burdened by joint pain and inflammation generally.
The Stanford researchers figured out how to regrow articular cartilage by first causing slight injury to the joint tissue, then using chemical signals to steer the growth of skeletal stem cells as the injuries heal. The work was published Aug. 17 in the journal Nature Medicine.
Cartilage has practically zero regenerative potential in adulthood, so once its injured or gone, what we can do for patients has been very limited, said assistant professor of surgery Charles K.F. Chan, PhD. Its extremely gratifying to find a way to help the body regrow this important tissue.

Damaged cartilage can be treated through a technique called microfracture, in which tiny holes are drilled in the surface of a joint. The microfracture technique prompts the body to create new tissue in the joint, but the new tissue is not much like cartilage.
Collagen For Knee Cartilage Healing
Do collagen supplements work to rebuild knee cartilage? The answer in short is, yes. Collagen is primarily found in various types of connective tissues around your knees such as cartilage, ligaments, tendons and bones. Collagen is one of the most important components which can contribute to cartilage repair and collagen can also stimulate cartilage regrowth. Collagen plays a vital role in supporting the growth and repair cartilage tissue over time as well as relieve joint inflammation and joint pain. Research has shown that Type 2 collagen is commonly found in knee joints, which are doing weight-bearing for your body but suffered from wear-and-tear during exercise.

Symptoms Of Torn Knee Cartilage
How do you know if you’ve sustained a cartilage tear?
You may experience acute symptoms like pain and buckling of the knee right after an injury, but not necessarily sometimes, cartilage damage can happen gradually over time, resulting in intermittent symptoms. Some people with meniscus tears have no pain and don’t even realize they have an injury.
However, even if you’re pain-free, you will likely note one or more of the following symptoms:
- pain or tenderness in the knee
- buckling or locking of the knee joint
- crunching or popping noises when walking
- dull pain under the kneecap when exercising
- difficulty bearing weight
- inability to bend or straighten the knee
- swelling or “water on the knee,” a buildup of fluid inside the knee joint
- tightness of the knee joint
Other Preventative Measures To Protect Your Knee Cartilage Are Also Vital
Unfortunately, no matter walking or exercising, this will put wear and tear on knee cartilage. Your cartilage will lose cartilage cells and collagen matrix due to wear and tear. Although taking collagen supplements can help to strengthen and protect your knee cartilage, the ability for your body to repair or regrow cartilage declines as you age and cartilage loss is eventually inevitable. How can you protect your knee cartilage if cartilage loss is inevitable? Whether you have to accept declining joint health? The answer is definitely not! Physical therapy or wearing knee pads can be alternative solutions to help you to reduce knee pressure. Hence it will be less wear and tear that your knee cartilage will suffer. The newly invented spring-loaded knee joint support pads can help you to reduce the pressure on your knees effectively.

Within the last decades, exciting advances in cellular research have allowed medicine to acquire a new area of focus- regenerative medicine. Regenerative approaches to medicine focus on encouraging the body to repair damaged or diseased tissue. In some areas, the body can be persuaded to recreate and integrate new tissue in the place of old tissue.
The regenerative medicine approach to the repair of tissues and organs damaged by injury, disease and aging is rapidly emerging as a disruptive technology that promises to transform healthcare worldwide. Through the overlap of cell and molecular biology, biomaterial and bioengineering disciplines, the vision of restoring and extending a patients normal, active lifestyle without the use of plastic, metal or foreign tissue parts is no longer science fiction. The use of cells, biomaterials and bioactive mediators, either alone or in combination, can stimulate and guide natural repair mechanisms to produce fully functional, native tissues. This bench to bedside translation of basic academic science principles provides new alternatives to the treatment of a diverse range of unmet clinical needs that encompass musculoskeletal-related conditions, soft tissue wounds, cardio- and peripheral vascular diseases, neurological disorders and stroke.
Q: Can Cartilage Repair Itself
A: Though it is made of cells and tissues, cartilage cannot repair itself due to the lack of blood vessels and enough blood supply to create and duplicate new cells. Some cartilage cells may be able to repair microscopic lacerations or tears but it will be difficult to recover from the wear and tear of excessive use over time.

What Is The Function Of Cartilage
Cartilage is a form of connective tissue that covers the end of each bone in the body. It provides cushioning and shock absorption to the joints, allowing them to move smoothly without restriction. When there is decreased cartilage within a joint, you may experience pain, stiffness, and difficulty moving your joints through their full range of motion.
A variety of treatments are used to treat loss of cartilage in the knee, ranging from conservative measures like pain medications, weight loss, and physical therapy to more invasive procedures like injections and surgery, depending on the severity of your symptoms and degree of cartilage loss.
Institute For Cartilage Repair
The HSS Institute for Cartilage Repair focuses on the treatment of symptomatic cartilage lesions. Articular cartilage, the cartilage that lines joints such as the knee, hip, ankle and shoulder, does not have the capability to repair itself. As such, injuries to cartilage surfaces often result in pain, poor joint function, and arthritis. The Institute for Cartilage Repair was developed by a skilled group of clinicians in response to growing clinical need for more durable cartilage and meniscal repair procedures. Its multidisciplinary team of surgeons, radiologists, clinicians, physical therapists, and researchers have focused on the problems of detecting and treating cartilage injury for many years and offer the latest in surgical treatment, diagnostic imaging, and clinical outcomes research. The Institute offers patients a comprehensive resource in specialty cartilage repair.

If youre able to walk without pain, give a silent shout-out to your cartilage.
Every time you take a step, this flexible tissue absorbs the load and transfers it to the bone, allowing you to move freely. But unlike bone, if cartilage gets damagedby injury, wear and tear, or inflammationit cant regenerate. Over time, the damaged tissue degrades, and walking becomes progressively more painful as the bones come in contact with each other.
If we can intervene when you first have that injury, this therapy would have the potential to buy you 10 or more years, or maybe youd never need a knee replacement, says Chow. Thats the dream.

Recovering From Knee Cartilage Surgery
You may not be able to fully weight bear until four weeks after surgery, although you should be able to drive after week two.
In the first week, your rehabilitation will focus on increasing your range of motion through manual manipulation and gentle exercises.
From then on, the physiotherapy programme will work on improving strength and mobility.
Most people are able to return to physical activity after six weeks, but it can take three to six months before you can fully recover.
Physiotherapy is very important in the recovery period, as building up the muscles and mobility is key to the long-term effectiveness of cartilage repair.

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.

Build Knee Cartilage Naturally
If you’re searching for ways to reduce your knee discomfort, Dr. Lars Richardson, an orthopedic surgeon with Harvard Medical School-linked Massachusetts General Hospital, describes a three-part strategy that may help.
First, he recommends that you drop some weight. If you’re packing some extra pounds, each added pound means you’re exerting four pounds of pressure on the joints.
To accomplish that goal, follow a well-balanced diet that includes foods good for the joints and cartilage. Engage in low-impact exercise regularly. After you lose those pesky pounds, your joints will experience decreased pressure and pain. Dr. Richardson notes that when your body mass index reaches a healthy range, your knees should feel the benefits.
Next, partner up with a physical therapist to develop a muscle-strengthening program that results in better knee function. Target your body’s core muscles along with the hip, quadriceps and hamstrings. With stronger muscles supporting your knees, they won’t feel as much stress, and your knee joint will be better stabilized.
Work with your physical therapist to improve your knee’s range of motion. By working to straighten your knee and achieving better overall motion, you’re likely to experience fewer troublesome symptoms, Dr. Richardson points out.
