Can Knee Cartilage Repair Itself

Is This The Gateway To Limb Regeneration Research

Can damaged knee cartilage repair itself?

These two findings lay important groundwork for future research because, one day soon, scientists will be able to identify those cells in salamanders not found in humans which enable salamanders to regenerate entire limbs.

When this happens, perhaps researchers will be able to reproduce these regenerator cells and create a cocktail mixture with human MicroRNA that can be injected into humans to repair joint injuries or maybe be developed into medicines that can prevent or reverse arthritis.

And, who knows? Maybe one day in the not too distant future, scientists will discover the key to regenerating entire human limbs so we humans can channel our inner salamander!

Symptoms Of Cartilage Damage

Symptoms of cartilage damage in a joint include:

  • joint pain this may continue even when resting and worsen when you put weight on the joint
  • swelling this may not develop for a few hours or days
  • stiffness
  • a clicking or grinding sensation
  • the joint locking, catching, or giving way

It can sometimes be difficult to tell a cartilage injury apart from other common joint injuries, such as sprains, as the symptoms are similar.

Why Cartilage Has Trouble Healing

The cartilage found in our joints is called Hyaline Cartilage. It is glassy and smooth so the bones connecting at our joints can glide over each other during movement. But when damaged cartilage heals, it doesnt always retain the same slippery state it had prior to injury. Cartilage can grow back with characteristics of scar tissue and fibrous cartilage, which is not ideal for joint movement.

The healing process is complicated by two unique cartilage distinctions.

  • Cartilage does not have nerves. This means that by the time you feel pain and other symptoms of a cartilage injury, it has likely already led to bone damage and it is the nerves in the bone that are signaling the pain.
  • Cartilage is avascular, meaning it does not have a blood supply, so there is very little nourishment to help the cells multiply and heal the damaged area.
  • Because of its difficulty healing and growing back, the amount of cartilage in our bodies is often considered finite what we have is what we have. Keeping it safe and intact is critical.

    Types Of Meniscal Tears

    Meniscal tears come in a variety of different types, which can affect potential treatments, symptoms or relevance.

  • One type of tear is a radial tear, which is just a left to right tear across the meniscus . These are the most common types. Most commonly they are in what we call the white zone of the meniscus where it does not get much blood supply. Thus they are hard to heal naturally, so if you see a surgeon they will likely try to cut this part out despite the evidence saying that a meniscectomy does not work.
  • The next type of tear is a horizontal tear, which is basically an up and down or front to back tear in the meniscus . Many times these tears are in a portion of the meniscus that does get blood supply so they could potentially heal on its own. If they do not heal naturally then surgical repair can sometimes be tried to help.
  • The next type of tear is a complex tear where you have a combination of different tears where it can be torn in multiple areas of the knee . Oftentimes when the surgeon sees these, they would attempt a meniscectomy again because most of the time these are difficult for them to try to repair.
  • Next type of tear is an intrasubstance tear. Usually these are just degenerative tears in the midportion of the meniscus. Typically, surgeons will not even try to operate on these. After age 30, these are very common findings of a meniscal tear on MRI, which is of little consequence.
  • Is It Possible To Rebuild Cartilage

    Can damaged knee cartilage repair itself?

    In general, it is not possible to rebuild cartilage once it is gone. For those who are affected by conditions like osteoarthritis, the cartilage in joints will likely continue to wear away year after year, until there is none left. The only way to restore the joint at that time is to do a full replacement. Other possible treatments may include pain medications and supplements to ease stiffness and prevent further loss.

    Although it is not possible to rebuild cartilage, some joints that are constantly painful may be replaced through surgery. Not all joints are eligible for this procedure, and the most common are the hips and knees. In most cases, an artificial joint is implanted into the body to replace the defective one. These new joints last upwards of 15 to 20 years, and pain is almost always alleviated entirely.

    There are some indications that certain supplements and emerging treatments may help make it possible to rebuild cartilage, but there is not any evidence as of yet to back these theories up. Glucosamine, for example, has been rumored to rebuild cartilage in the joints of those who suffer from arthritis and other chronic conditions. Medical treatments are also under development, but they are not completed and have not been tested for effectiveness.

    Why Does Damaged Cartilage Heal Slowly

    Cartilage heals slowlycartilage

    why does injured cartilage take a long time to heal?

    Cartilage, like bone, is surrounded by a perichondrium-like fibrous membrane. This layer is not efficient at regeneration of cartilage. Hence, its recovery is slow after injury. The lack of active blood flow is the major reason any injury to cartilage takes a long time to heal.

    What Surgical Procedures Are Available

    Many procedures to restore articular cartilage are done arthroscopically. During arthroscopy, the procedure is done through 2 small incisions . Some procedures require direct access to the affected area via an open incision . In general, recovery from an arthroscopic procedure is quicker and less painful than traditional, open surgery. Your doctor will discuss the options with you to determine what kind of procedure is right for you.

    The most common procedures for damaged cartilage are:

    • Chondroplasty
    • Osteochondral Autograft Transplantation

    Why can’t cartilage repair itself?

    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.

    Can Cartilage Heal On Its Own

    Cartilage is an extremely important structure of the body. It is a firm band of tissue that connects bone to bone. It protects the bones from rubbing against each other which can result in early degeneration of the bones giving rise to painful conditions like arthritis.

    Cartilage can be found in various joints of the body like the elbow, knee, hip, ribs, ankles, and even in the ears and nose however, the cartilage in the knee joint is more vulnerable to injuries and damage as it is the knee joint which is perhaps the busiest weightbearing joint in the body along with ankles and hip.

    A damaged cartilage can lead to severe pain and restriction motion, especially in the knee joint. This article gives a brief overview of whether cartilage can heal on its own.

    Our Unique Approach To Articular Cartilage Repair

    Early identification and treatment of articular cartilage damage can have a significant effect on outcomes for patients. We address cartilage damage as part of our biologic joint replacement procedure. By repairing or replacing the damaged cartilage before it completely wears out, the arthritic damage can be reversed and the joints preserved.

    If this step is not taken, eventually the cartilage wear will progress so much that the bones will touch on each side of the joint, called bone on bone wear. At this stage, artificial joint replacement becomes necessary.

    Stem Cells And Tissue Engineering

    Current research focuses on new ways to make the body grow healthy cartilage tissue. This is called tissue engineering. Growth factors that stimulate new tissue may be isolated and used to induce new cartilage formation.

    The use of mesenchymal stem cells is also being investigated. Mesenchymal stem cells are basic human cells obtained from living human tissue, such as bone marrow. When stem cells are placed in a specific environment, they can give rise to cells that are similar to the host tissue.

    The hope is that stem cells placed near a damaged joint surface will stimulate hyaline cartilage growth.

    Tissue engineering procedures are still at an experimental stage. Most tissue engineering is performed at research centers as part of clinical trials.

    What Is The Outlook For People With Articular Cartilage Injuries

    Articular Cartilage Injury

    The outlook is good for patients with these injuries, although not everyone will be able to resume all activities. Pain and discomfort can be relieved with both nonsurgical and surgical treatments. When the articular cartilage is damaged, surgical procedures can effectively repair and restore the tissue. In general, healthy individuals younger than 40 with minor articular cartilage injuries have the best outcomes and often successfully return to pre-injury activities. But not every patient is a suitable candidate for cartilage restoration or repair. These procedures are ideal for active people under age 50.

    If left untreated, articular cartilage injuries can lead to the development of osteoarthritis, a condition in which the articular cartilage wears away, exposing the underlying bone. Joint replacement surgery may be required to treat osteoarthritis.

    When To Get Medical Advice

    If you’ve injured your joint, it’s a good idea to try self care measures first. Sprains and minor cartilage damage may get better on their own within a few days or weeks.

    More severe cartilage damage probably will not improve on its own. If left untreated, it can eventually wear down the joint.

    Visit your GP or a minor injuries unit if:

    • you cannot move the joint properly
    • you cannot control the pain with ordinary painkillers
    • you cannot put any weight on the injured limb or it gives way when you try to use it
    • the injured area looks crooked or has unusual lumps or bumps
    • you have numbness, discolouration, or coldness in any part of the injured area
    • your symptoms have not started to improve within a few days of self-treatment

    Your GP may need to refer you for tests such as an X-ray, MRI scan, or arthroscopy to find out if your cartilage is damaged.

    Fiber: The Solution On Your Plate

    High Fiber Foods and Their Benefits by Urbanwired1 Flickr

    The key to alleviating and even avoiding knee pain might be closer than you think! Just look down at your plate. Are you eating enough fiber?

    New research in the journal Annals of the Rheumatic Diseases has shown that people with fiber-rich diets have a reduced risk of knee osteoarthritis. This is huge, as two separate studies consistently showed that higher total fiber intake was related to lower risk, with statistically significant results!

    The first study, Osteoarthritis Initiative, examined nearly 5,000 participants and the second study, the Framingham Offspring, examined more than 1,200. Both studies concluded that the more fiber you eat, the less likely you are to experience knee pain, and the less likely you are to be diagnosed with knee arthritis.

    Keep in mind that correlation does not imply causation, and the studies did not prove that fiber heals knee pain, only that something is going on with the nutrients that are almost certainly good for you.

    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.

    What Is The Function Of Cartilage

    Can the Meniscus Tear in Your Knee Heal On Its Own? Knee Cartilage

    Cartilage is the cushion at the end of our bones that prevents our bones from rubbing against each other and causing pain. It is soft enough to change its shape and absorb compressions in our joints whenever we stand, move our wrists, or sit.

    Cartilage is made of four substances: collagen, proteoglycans, water, and chondrocytes. Water makes up 70% of the cartilage, and when we stand, it acts like a sponge to handle the compression. The cartilage covers the end of the bone, changes its shape, and squeezes water to coat your knee joints. Once you sit, the cartilage decompresses and reabsorbs the water released to your joints.

    When we were younger the tips of our bones used to be cartilage that developed into bones as we grew older. However, as an adult, you can still find cartilage in several parts of your body aside from your joints. The types of cartilage in our body are:

    • Hyaline cartilage or articular cartilage is a springy but tough type of cartilage that covers your ribs, supports your windpipe, and protects your joints.
    • Elastic cartilage is a type of cartilage with a springy form and can be found in our ears and nose.
    • Fibrous cartilage is the weight-bearing type of cartilage that is found in your spine and hips.

    Surgery To Repair Torn Cartilage

    Arthroscopic surgery is commonly used to treat cartilage tears, such as a torn meniscus in the knee. This surgical method allows the surgeon to see, diagnose, and treat problems inside a joint in a minimally invasive manner, thereby causing less trauma to the tissue and enabling quicker healing afterward. Arthroscopic surgery uses small, narrow surgical instruments that are inserted through very small incisions.

    The arthroscope comprises a lens and a lighting system which has a fiber-optic camera function at the end. This allows the surgeon to view magnified, real-time images on a video screen, and to take photographs and video of the inside of the joint.

    Role Of Pulsed Electromagnetic Fields : I

    Preclinical studies have shown that pulsed electromagnetic fields , with specific physical signal parameters ,in vitro favor the proliferation of chondrocytes, stimulate proteoglycan synthesis, and demonstrate A2A adenosine receptor agonist activity.-In vivo, I-ONE therapy prevents degeneration of articular cartilage and downregulates the synthesis and release of proinflammatory cytokines in the synovial fluid.- These findings suggest that I-ONE therapy may be used in humans to control joint inflammation and to stimulate cartilage anabolic activities, finally resulting in chondroprotection. Clinical studies show that I-ONE therapy is an effective chondroprotective treatment for patients, without any negative side effects, that limits inflammation, reduces recovery time, and ultimately preserves a healthy articular cartilage of the knee., The positive results are maintained also at 3 years follow-up. Our authors from Milan prospectively followed up 32 patients treated with I-ONE therapy for 1 year . Patients showed significant improvement in all scores at final follow-up . The data of their work further confirm the findings of previous clinical studies, which showed the benefits of using I-ONE therapya noninvasive, specific, and local biophysical treatmentin order to control the inflammatory process and to provide faster functional recovery without any side effects.
