How To Tear Your Meniscus On Purpose
Not Likely!: I can't imagine anyone wanting to tear the meniscus in their knee on purpose. Quite painful and significantly debilitating in the short term depending on the extent. Usually one tears their meniscus by accident while trying to go one way and their knee going awkwardly in another direction. For example, like planting your foot and twisting in the opposite direction for a kick. ...Read more
Rotational force on : Most tears of the meniscus occur from a rotational force on the knee joint. Surprisingly, this force does not need to be that great to cause a tear of the meniscus. Perfect example is sitting cross-legged(indian style), is enough force to tear it. ...Read more
Rare but can occur: The goal of partial meniscectomy is to negate the symptoms of pain, catching and swelling that are common with a torn meniscus. When a portion of meniscus is removed, there is less left to possibly tear again, so it makes sense that retear becomes less likely. A partially respected meniscus, however, may still have remnants of less than normal tissue that can be susceptible to retear. ...Read more
How easy is it to tear your meniscus? I am not going to do this. I was just wondering because my friend tore his yesterday but I saw him yesterday.
It depends: The meniscus in a young person is thick and strong like rubber. In an older person it thins out and the substance of it is not as strong. A young person needs a very high energy twisting type of injury. An older person might get the tear from walking or going up/down stairs or squatting. Not all tears are the same and small frayed edges (small tears) are more common than large. ...Read more
Rotation: Meniscus tears occur either a medial or a lateral force directed to a flexed knee. When the foot is planted and the knee is flexed and either internally or externally rotated, the meniscus becomes vulnerable to injury. At this point, the addition of a force applied to the lateral (or medial) aspect of the flexed knee may tear the medial (or lateral) meniscus. Medial tears are more common. ...Read more
Yes: Unfortunately, we can tear the meniscal cartilage in the knee. In younger patients, this is usually the result of significant trauma, such as a sports injury. As we age, sometime a patient can tear the cartilage with minimal trauma or a twisting injury to the knee. Some patients cannot remember the exact injury to the knee, since at the time the injury did not seem significant. ...Read more
Pain in the knee: Few things for diagnosis of meniscal tear including, clicking of the knee when trying to move it, the knee is stuck in one position and will not move, pain right over the joint line on either the inside or the outside of the knee, and swelling are all common. ...Read more
Yes.: It is possibly if you had some type of re-injury to the same knee. Or, if you have other things going on inside the knee, that made it more vulnerable to a re-tear. ...Read more
Not always.: The goal of arthroscopy for treating a meniscus tear is to remove the portion that is causing the symptoms (pain, swelling, & catching). The remaining meniscus is usually stable & less likely to retear because the unstable portion has been removed. A good analogy is trimming a hangnail to avoid propagation of the tear and prevention of further injury (except arthroscopy is performed under water). ...Read more
Can you re-tear a repaired meniscus? I had it repaired 14 months ago, and just this week it started to twinge.
Only if Trauma: Yes you can retear if you have new injury in the joint involved, But without trauma a spontaneous tear is unlikely after 14 months. If the pain persists or gets worse, get it checked ...Read more
How does a meniscus get displaced in the first place? I have been trying to find out if a displaced meniscus root is a tear at the attachment?
Root Tear=Displaceme: A tear of the meniscal root leads to displacement of the meniscus. 2 of the main attachments of the meniscus are at the root both in the front and back up. ...Read more
How can you tell how much of your meniscus is torn? Can you tell without invasion test? Had meniscus tears for 4 years and 2 ops and torn it again?
Is there an underlying cause to numerous meniscus tears over time? I'm a healthy, active 32 year old female who has had multiple tears over 14 years
No specific cause: There is not likely a specific underlying cause. Once a knee has an injury, it is no longer a stable as it once was and has a higher risk of re-injury. As you injury it multiple times that re-injury risk goes up. At times genetics can play a role as can being involved in the same activities that caused the injury in the first place. Furthermore, body mechanics can be a factor. ...Read more
You can't: A medical professional should be able to give you a working diagnosis regarding likely or not likely a 3rd degree sprain, or full tear. Without MRI or arthroscopy, we can only be mostly correct regarding damaged meniscus or not. Being able to walk on that leg does not rule out torn meniscus, nor does the absence of swelling. The pain will eventually subside even with treatment. ...Read more
U would only know U-: -have a torn meniscus if U have already seen an orthopedic surgeon, a you would have got if you were having symptoms. So if you have locking, giving way, pain planting your bad leg & pivoting, you are doing damage 2 the joint surface which can lead 2 life long problems. Whether you have surgery is up 2 you. After recommendations, it is up 2 U 2 decide, not anyone else. ...Read more
Lots of options: Sometimes it can be as easy as leaving it alone and doing some exercises to help the knee joint unload. Other times it might involve surgery. I would see an orthopedic surgeon to assess your status. There have been some recent advances in the stem cell therapy that might be helpful in healing the tear rather than cutting it out in surgery. Look into regenexx. ...Read more
Yes, it can, BUT it-:
Is rather unlikely, as they generally don't, unless the tear is a minor one. I don't think they heal but they certainly become symptom-free.
Surgery can help certain types of the tears by repairing them which are dependent on the specific site they occur in. Most are however not amenable to repair. ...Read more
Most tears do not heal.
Only the outer third of the meniscus has a blood supply to heal itself but this is not the common way they tear.
But, it is common for some small tears to calm down after a week or two and they can be asymptomatic for weeks or months, sometimes years with little tears. ...Read more
