What is the white zone of the meniscus?
The vascular portion is called the “red zone” due to the presence of capillaries in the meniscal tissue. The avascular portion is called the “white zone” due to its absence of blood supply. Red zone tears have the potential to heal and white zone tears will likely never heal.
Is the medial meniscus in the white zone?
Meniscus tears can occur medially or laterally (inside or outside menisci) in the red zone, white zone, or in both.
What are the three zones of the meniscus?
You can break up the meniscus into three zones, the anterior horn, the body, and the posterior horn. One of the problems the meniscus runs into is that because it is a cartilage, it lacks a certain amount of blood flow to the tissue for proper healing properties.
Is it better to repair or remove meniscus?
In general, it’s better to fix the meniscus than to remove it. Some types of tears can’t be fixed. For example, radial tears sometimes can be fixed, but it depends on where they are. But most horizontal, long-standing, and degenerative tears—those caused by years of wear and tear—can’t be fixed.
What is a Grade 3 meniscal tear?
Meniscus tears, indicated by MRI, are classified in three grades. Grades 1 and 2 are not considered serious. They may not even be apparent with an arthroscopic examination. Grade 3 is a true meniscus tear and an arthroscope is close to 100 percent accurate in diagnosing this tear.
Will walking on a torn meniscus make it worse?
In serious cases, it can develop into long-term knee problems, like arthritis. In addition moving around with a torn meniscus could pull fragments of the cartilage into the joint causing larger knee issues which could requiring more significant surgery in the future.
Is a medial meniscus tear in the red zone or white zone?
Tears at the outer edge of the meniscus ( the red zone ) tend to heal well. Blood supply to tears that extend into the center of the meniscus (white zone) is questionable, and surgical repair of a tear in this zone may not heal well.
Which is worse lateral or medial meniscus tear?
Is the lateral meniscus tear worse than a medial meniscus tear? It is hard to differentiate what type of tear is worse if it is repairable. However, it is well known that if a lateral meniscus is taken out, the consequences are almost always worse than having a medial meniscus resected.
Can meniscus be repaired without surgery?
Not all meniscus tears require surgery. That said, very few meniscus tears will heal completely without surgery. 1 It’s important to understand that not all meniscus tears cause symptoms, and even if a meniscus tear occurs, the symptoms may subside without surgery.
How important is the meniscus?
The meniscus has an important function inside the knee as a shock absorber that helps distribute the load of the body. If the entire meniscus is removed, the rest of the joint gets overloaded and the knee is susceptible to arthritis. This is why the surgeon will save as much of the meniscus as possible.
What type of meniscus tear requires surgery?
The most common type of tear to the meniscus is a radial tear. This type of tear occurs in the area of the knee that isn’t supplied with blood, so it cannot heal on its own. Surgery may be required if the tear is severe. In the case of a radial tear, the surgeon will trim away the damaged part of the meniscus.
How do I know if I have a lateral meniscus tear?
Symptoms of a lateral meniscus tear may include tenderness and pain around the outside surface of the knee, particularly along the joint line. With a lateral meniscus tear, there is typically swelling which appears within 24 to 48 hours of the injury occurring.
What is the fastest way to recover from meniscus surgery?
Rest, ice, compression, and elevation (R.I.C.E) are recommended for patients recovering from any kind of surgery, include meniscal repair. Keep these guidelines in mind to make sure you’re getting the most out of this approach: Avoid whatever activity caused your injury and rest as often as possible.
What is the recovery time for a meniscectomy?
Recovery will take about four to six weeks, depending on the surgical approach used. The recovery period following arthroscopic surgery is usually shorter than that for open surgery. Other factors that affect recovery time include: type of meniscectomy (total or partial)
Why does meniscus tear hurt at night?
There are a couple of reasons why your knee pain is worse at night: Pain is perceived to be worse at nighttime. As you climb into bed and start to quiet your mind pain becomes more pronounced than when you were active during the day distracted by your activities. An active day may cause your knee joint to swell.
