Meniscal tears are the most frequently encountered and treated injuries in the knee joint, with a bimodal age distribution in young, active sports people and in elderly people, and with a relatively high annual cost. Similarly, meniscal tear surgery is among the most commonly performed procedures in orthopaedic surgery.
The collagen meniscus implant (CMI) is back on the US market, and it has the potential to change the way knees are treated. Here is why...
Meniscal injuries have posed a challenging problem for many years, especially considering that historically the meniscus was considered to be a structure with no important role in the knee joint. This led to earlier treatments aiming at the removal of the entire structure in a procedure known as a meniscectomy. However, with the current understanding of the function and roles of the meniscus, meniscectomy has been identified to accelerate joint degradation significantly and is no longer a preferred treatment option in meniscal tears. Current therapies are now focused to regenerate, repair, or replace the injured meniscus to restore its native function.
The lateral and medial menisci are crescent-shaped fibrocartilaginous structures that collectively cover approximately 70% of the articular surface of the tibial plateau, and primarily function in load transmission and shock absorption through the tibiofemoral joint.
A patient comes in with knee pain, and an MRI shows a torn meniscus; naturally, the patient wants it fixed, and the surgeon wants to fix it and send the patient for physical therapy. And patients do get better, just not necessarily from the surgery.
The Finnish study does not indicate that surgery never helps; there is consensus that it should be performed in some circumstances, especially for younger patients and for tears from acute sports injuries. But about 80 percent of tears develop from wear and aging, and some researchers believe surgery in those cases should be significantly limited.
Go to the doctor with knee pain, and they might say you've got a meniscus tear and need surgery to fix it. But surgery for this common problem might not be any better at relieving pain than having no surgery at all, according to researchers who went to the trouble of performing fake surgery to find out.
Meniscus tears are VERY common... even in people who do not even know it! Not all meniscus tears require surgery. The more you learn, the better off you are. We treat patients, not MRI findings... and your physicians needs to take into account your quality of life and limitations to determine what the proper treatment plan should be for your meniscus tear and knee pain.
Meniscal tears are relatively common knee injuries that are encountered in almost every sport. Virtually every young athlete has either personally dealt with a meniscal tear or knows of a teammate that has battled one.
First, never consider having a surgical procedure without a second opinion from someone you trust. By this I do not mean a family friend, I mean someone with great credentials in your local community.
Now, however, there is new approach to fixing torn and missing meniscus tissue, called the Collagen Meniscus Implant (CMI). The CMI is a biological device made of highly purified collagen, which is designed to promote a self-healing process by acting as a trellis for new meniscus tissue to grow into, reconstructing missing segments of the meniscus shape.
It is intuitive to think that when something is broken in the knee, fixing it with surgery is necessary. Research shows this is not necessarily so. Surgery is not the only solution. Research shows that several types of knee problems can resolve to a similar extent without surgery, but surgery or not, an excellent outcome cannot be guaranteed.
Here is everything I tried in an effort to avoid the knife.
The typical surgical response, an arthroscopic partial meniscectomy, doesn’t appear to be any better than a regular exercise program for most people.
Many studies have now shown the outcomes from arthroscopic surgery for osteoarthritis and degenerative meniscal tears are no better than the outcomes from placebo (fake) surgery or other treatments (such as exercise therapy).
Middle-aged and older patients are unlikely to benefit in the long term from surgery to repair tears in the meniscus, pads of cartilage in the knee, a new review of studies has found.
Researchers at McMaster University combined data from seven randomized, placebo-controlled trials involving more than 800 subjects treated for meniscal tears with surgery, sham s
Patients who suffer from osteoarthritis and who also have a meniscal tear represent a challenge to medical providers because it is often not clear which condition is more adversely contributing to pain as well as their disability.
While less common than a tear of the meniscus — the rubbery cartilage that works like a shock absorber in your knee — a root tear is more devastating. The root holding the meniscus to the bone tears away.
The latest controversy — and the operation that arguably has been studied the most in randomized clinical trials — is surgery for a torn meniscus, a sliver of cartilage that acts as a shock absorber in the knee.
Scientists test implanting an artificial meniscus or inducing the body to grow a new one.
