Injections For Knee Pain

Can damaged knee cartilage repair itself?

Valaik says theres good science behind cortisone shots and other injections, such as hyaluronic acid injections, that lubricate the inner workings of the knee and help relieve arthritis pain.

According to Valaik, there is less evidence supporting the benefits of other injectable substances, including platelet-rich plasma and concentrated bone marrow or stem cells, but further studies will reveal more about their efficacy in treating knee arthritis.

Injections can provide temporary relief typically a few months which can help you stay on your feet and postpone surgery, he says.

Arthroscopy For Articular Cartilage Damage

The cartilage that coats your bones is called articular cartilage. In almost all cases, your surgeon will carry out a cartilage repair operation arthroscopically using a tiny camera view the inside of your knee on a monitor.

Small surgical instruments are used to remove, trim or smooth cartilage with precision, reducing the impact on other structures of your knee.

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.

Is Irreversible Cartilage Damage Still A Fact Of Life

Cartilage cells are vital as cushions inside the joints of the body. Healthy cartilage tissue keeps joints smooth, flexible and pain free. If the cartilage tissue becomes damaged, this damage tends to be permanent. Joints become painful and lose their flexibility. Cartilage cannot regenerate naturally inside the body.

After some time the bones start to collide. The joints start to become inflamed and permanently stiff, unless a prosthetic joint is implanted. This painful process represents the irreversible development of osteoarthritis.

  • Immediate and lasting pain reduction
  • Restoration of resilience
  • Reconstruction of the cartilage layer using new cartilage through a natural process
  • Prevention of or delay in the need for joint replacement

Oats Osteochondral Autologous Transplant System

Knee Cartilage Repair, Regeneration, and Replacement

This technique can be used for larger lesions of more than 2cm squared. This technique utilises small cylindrical autologous cartilage grafts – the term autologous meaning that the cartilage is taken from the patient themselves and not a donor. What this means is that small plugs of cartilage and underlying bone are taken from the part of the joint that is not involved in weight-bearing and is, therefore, not an essential part of the joint. These plugs are then taken from the donor site and plugged into the area where there is missing cartilage.

The advantages of OATS are that the transplant of hyaline cartilage is used and that the technique can be performed in a single surgery.

There Are A Variety Of Treatments For Cartilage Damage In The Knee Ranging From Pain And Anti

Cartilage transplant surgery is usually an option for patients who have damage that is localized rather than widespread. It is an excellent choice for athletes and others who arent ready for total knee replacement. While total knee replacement surgery is a great option for some patients, the decision of whether it or a cartilage transplant is right for you is up to you and your surgeon based on your knee issues and personal goals.

According to theAmerican Academy of Orthopaedic Surgeons, cartilage transplants have demonstrated excellent long-term outcomes, with consistent improvementsas well as reliable return to prior levels of activity.

Who Can Get Cartilage Transplant Surgery?Cartilage transplant surgery is not for everyone with knee arthritis or knee cartilage damage. The procedure is usually recommended for patients who fit specific criteria, some of which include:

  • Under the age of 55
  • Healthy and physically active
  • Knee pain for a relatively short duration
  • Those who have pain even when resting
  • Localized, not widespread, cartilage damage

Types of Knee Cartilage Transplant SurgeryThe majority of knee cartilage transplant surgeries fall into two categories: osteochondral autograph transplants or osteochondral allograft transplants. There is also another less common surgery called autologous chondrocyte implantation.

How Long Is The Recovery Period After Surgery

The best results are in patients who follow the rehabilitation guidelines well. Following the surgery, the area that has been treated must be protected using a brace, crutches and protected weight-bearing for six weeks followed by a rehabilitation process going on for up to six months or more. Cartilage cells are slow-growing and can take up to 18 months to fully form new cartilage. Therefore, strict adherence to rehabilitation programmes is very important.

Instead Of Knee Replacement Surgery Cutting Edge Medicine Regenerates Cartilage For The Joint

Matt Oates, 41, ran competitive track and cross-country in high school and college, then kept on running. On New Years Day 2018, he resolved to run every day that year, and he did a total of 2,435 miles, including 14 half-marathons. He has had a few injuries, most of them minor, except in 2005 when he tore the ACL the anterior cruciate ligament in his right knee while playing indoor volleyball. He recovered from surgery, and resumed running.

In 2019, however, he slipped and fell while frolicking with his young nephew in a natural waterfall during a Memorial Day outing at Georgias Kennesaw Mountain National Battlefield Park. I didnt think too much of it at the time, says Oates, who lives in Raleigh, N.C., where he manages a moving-and-storage company. My right knee hurt, but I ran through the pain. But my knee would swell, and it was impacting my stride.

In January, he finally had an MRI, which showed he had torn his meniscus, a common sports injury to the cartilage that cushions the area between the shinbone and thighbone. But there was more. The scan also revealed an area under the kneecap where the cartilage had worn away, which often portends full-blown osteoarthritis and possible knee replacement years later. Unlike bone, which has the ability to heal, cartilage cannot restore itself once injured.

Barker extracted the cartilage cells while repairing Oatess meniscus, and implanted the membrane into Oatess knee in September.

Articular Cartilage Paste Graft

How To Tell If Youve Got A Knee Cartilage Problem – 3 Tests You Can Do At Home

At The Stone Clinic, we have a unique procedure for repairing articular cartilage: the Articular Cartilage Paste Graft, designed by Dr. Stone in 1991.

Articular cartilage paste grafting uses your own bone, cartilage, and marrow cells to regenerate your damaged cartilage. It is a minimally invasive, single arthroscopic procedure that stimulates regrowth of damaged articular cartilage surfaces.

The arthritic area of the knee, or the area where there is missing cartilage, is morselized by the surgeon to create a fresh blood supply and to bring marrow cells to the surface. The graft is harvested from the intercondylar notch , crushed into a paste, and packed into the fractured chondral defect. The result is a repair technique that can provide durable cartilage repair tissue with long-term improvement in function and diminishment of pain.

“Articular cartilage paste grafting has provided my patients with tremendous relief and permitted a return to sports for many arthritic joints that were thought to require joint replacement. Our published peer reviewed long-term outcome studies have matched or exceeded any other published work. Paste grafting has been a great tool for salvaging failed microfractures and other cartilage procedures.”

Cartilage Restoration: Knee Renewal Instead Of Replacement

When you cut yourself or break a bone, your body immediately works to heal that injury, sending nutrients through the bloodstream to repair and restore the damaged tissue. But if your cartilage is damaged, youre out of luck. This soft, flexible tissue that cushions the joints has no direct blood supply and thus little ability to heal itself.

Cartilage is the smooth protective covering lining the ends of the bones at the joints, and is very important within the knee joint, particularly. “Normally, cartilage acts as an effective shock absorber, tough enough to survive both the wear and tear of daily activities and high level sports, explains Dr. Steven Hale, orthopaedic specialist with Center for Orthopaedics, an affiliate of Imperial Health. “It has an extremely low friction surface that enables the knee to bend and move easily and painlessly.

However, cartilage can become damaged through injury or as a result of the wear and tear that occurs over years, according to Dr. Hale. “A traumatic injury, such as falling and twisting your knee, usually causes a more localized type of cartilage injury. Damage due to wear and tear, otherwise known as degenerative arthritis, or osteoarthritis, occurs over a lifetime. In many cases, it may start as a localized area of damage, but progress to involve larger areas of cartilage damage, leading to further wearing away of cartilage, bone damage and painful movement.

Growing Cartilage In The Lab

There are surgical procedures that use cartilage cells that have been harvested from a patient, cloned and reproduced in a lab, and then reinserted into the patient. However, these cartilage cells can only be inserted into relatively small voids in the cartilage, not to “resurface” a worn out, arthritic joint.

There are possible solutions for patients with a limited area of cartilage damage, but this is not an arthritis treatment. These cartilage replacement techniques are for patients with limited areas of cartilage damage, often caused by sports or traumatic injuries.

For replacement to succeed, areas of cartilage damage have to be smallnot the widespread damage seen in arthritis.

Talk With A Doctor About Which Procedure Is Right For You

If youre experiencing knee pain, have a discussion with your primary care physician. They can refer you to a physical therapist or an orthopedist who specializes in knee health. The solution isnt always surgery, though for severe cartilage damage, some invasive intervention is likely.

Your age and activity level are two key factors in determining what approach is best for you. The nature and severity of the problem in your knee is another factor.

Be sure to talk with your doctor about whats involved in various procedures and recovery periods. Its also important to find out the costs of a procedure and how much of that expense will be covered by your insurance.

Regardless of which knee cartilage treatment you have, you should be prepared for a lengthy recovery and rehabilitation phase. A study in the

Who Are Candidates For Cartilage Surgery


Most candidates for cartilage repair are young adults with a single injury, or lesion. The size of the lesion, site of the lesion and the status of other structures in the knee will determine whether surgery is possible for you. Often, additional operations such as knee re-alignment and ligament reconstructions may also be required to improve the chance of success. Older patients, or those with many lesions in one joint, are less likely to benefit from the surgery, as this process is more representative of OA.

Do I Need Surgery If I Have No Cartilage Left In My Knee

Joint replacements are some of the most common surgeries in orthopedics. Patients with pain from arthritis in their knees, hips and shoulder try non-surgical treatments to overcome that pain. At some point, they decide they want surgery to try to get relief. In this Ask Dr. Geier video, I discuss surgical and non-surgical treatment options if you have no cartilage left in your knees.

Angelo asks:Do I have to undergo knee surgery if both my knees are bone on bone with no cartilage left?

Bone-on-bone arthritis, meaning there is little to no cartilage remaining and no space between the tibia and femur can certainly be an indication for a knee replacement. An x-ray finding alone, though, doesnt necessarily mean you need a total knee arthroplasty.

Its reasonable to try non-surgical measures to see if you get relief. Cortisone shots, viscosupplementation, physical therapy, braces, anti-inflammatory medications, platelet-rich plasma and stem cells can all be options to try to decrease pain from arthritis.

If none of those treatments are working, surgery can be an option. Unfortunately, arthroscopic surgery to look in the knee and clean up the worn out cartilage probably wont do much to improve your condition. Knee replacement can be the best option if you truly have no cartilage.

What Exactly Is Cartilage Regeneration And How Does It Work

Cartilage regeneration aims to regrow cartilage in the area where it has been damaged or lost. Once the cartilage has been damaged or lost, there is no covering of the bone and therefore, with every step, the bodys load is transmitted to the underlying bone and this is perceived as pain. This also results in inflammation of the joint and the surrounding cartilage can also break down. The situation can worsen and result in a degenerate joint .

Cartilage regeneration is a technique that has been developed over many decades to help restore cartilage in areas of the knee that have lost the cartilage overlying the bone. There are two types of cartilage conditions:

  • There is generalised widespread cartilage damage, which is also known as osteoarthritis. In the case of osteoarthritis, the cartilage generally cannot be restored with surgery it can only be replaced using partial or total knee replacement surgery.
  • The second type of cartilage loss is something called chondral lesions. These are small and localised areas and the lesions are usually caused by trauma where a small area of cartilage has been damaged or lost. This causes pain for the individual and these can be treated successfully with cartilage regeneration.

Looking For Alternatives To Total Knee Replacements

We’re also funding research which is investigating alternative approaches to total knee replacement. For example, total knee replacement is not recommended for many young people. This study aims to develop a new method called ToKa®, which uses images of the patient’s joint and specially designed software to design a patient specific implant that will be made via 3D printing. If successful, this technique could prevent osteoarthritis patients from needing total joint replacement.

Less Common Surgical Procedures

There are also a number of alternative surgical techniques sometimes used to treat cartilage damage, including:

  • allograft osteochondral transplantation similar to mosaicplasty, but the replacement cartilage is obtained from a recently deceased donor, and is used to repair larger damaged areas
  • autologous chondrocyte implantation the surgeon first takes a small sample of cartilage cells from the joint these are then used to grow more cells in a laboratory and the new cells are used to replace the damaged cartilage
  • artificial scaffolds a special patch or gel is used to repair the damaged cartilage it may be used in combination with marrow stimulation or on its own

These procedures are only carried out in a few hospitals in the UK and are not routinely provided on the NHS. You may be able to pay for them privately, but they can be very expensive.

Coaxing Knee Cartilage To Regrow

Technique Offers Long-Lasting Pain Relief, Delays Knee Replacement Surgery, Study Shows

March 9, 2006 — A new study shows that regrowing knee cartilage might help people delay knee-replacement surgery.

Cartilage covers the knee’s bones. With wear and tear, cartilage gradually softens, then cracks, and finally develops large holes. Without cartilage to serve as a shock absorber, knee bones rub against each other, causing pain and more damage.

The technique used in this study spurs knee cartilage to grow back, which could cut pain and improve knee function, write Kevin Stone, MD, and colleagues.

Stone’s study appears in The Journal of Arthroscopic and Related Surgery.

A New Option To Rescue Knee Cartilage

New clinical trial is evaluating a next-generation approach to replacing damaged knee cartilage with healthy cartilage cultivated from a patients own cells.

Cartilage, the slippery tissue on the ends of and between bones, provides cushioning and shock absorption. Specifically, in the knee, the articular cartilage at the end of the thigh bone can become damaged from sports or other injuries, or even some illnesses, resulting in progressive pain and loss of mobility.

While a number of surgical procedures have been developed to restore or transplant cartilage, each is limited by the same thing. Compared with other body tissues, cartilage has a poor blood supply, and therefore limited potential to heal itself or to support donor cartilage.

Can Knee Cartilage Repair Without Surgery

Can knee cartilage repair without surgery? Cartilage is essential for the free and painless movement of any joint. A common injury to the knee is to the cartilage in the joint. Cartilage often referred to as hyaline cartilage in the knee is soft and spongy and has a number of functions. Firstly, it acts as a shock absorber, absorbing pressure and stopping bone on bone contact during jumping walking and running. Secondly, it maintains the synovial fluid within the joint with the right concentrations of salts and other substances. Finally, it provides a smooth surface for joint movement to occur on. By having a smooth surface and stopping bone on bone contact the joint is able to move freely and without pain. As such, when this cartilage is damaged, pain and an inability to move the joint can occur. This can come on slowly, in the case of osteoarthritis or suddenly, as in the case of a meniscus injury from a twisting motion in sports like Football or Tennis. Either way, the cartilage is often repaired using surgery but this is associated with a number of risks and is not always ideal for older patients. So can knee cartilage repair without surgery?

As we have seen there are options for knee cartilage repair that do NOT involve risky surgery. Regenerative medicine could be the breakthrough many doctors have been waiting for as it is associated with so few risks and has so many benefits.
