Torn Meniscus (Definition)

In the knee joint there are two types of cartilage, articular cartilage and meniscal cartilage. The meniscus is a triangular shaped piece of fibro-cartilage that sits between the femur and tibia. The meniscus can tear as a result of injury or secondary degenerative changes that occur over time. Because the meniscus cartilage dies not have it's own blood supply, tears often ...Read more

I've been told I likely have a minor lateral meniscus tear. With conservative treatment only, what could I generally expect as recovery time?

Estimated 3-6 months: Conservative/nonsurgical care for a lateral meniscus tear can include relative rest- esp. From high-impact/cutting activities such as running, heavy hiking, sports, exercise classes; physical therapy; regenerative injections such as platelet-rich plasma and bracing. Meniscal tears are slow to heal as blood supply is poor. If I can help, then join my care team at www. Healthtap. Com/dr-clarkeholmes ...Read more

Thanks for advice on here, I had mri shown lateral meniscus tear heading to ortho in a week. What should I expect, same leg as previous TTT?

Arthroscopy: The orthopedist may suggest an arthroscopic repair. This would be the most logical approach. Any subsequent therapy would come after a full objective examination of the joint space. ...Read more

What's the key difference between a knee sprain and a small lateral meniscus tear?

What's the key difference between a knee sprain and a small lateral meniscus tear?

Ligament/cartilage: A knee sprain is a stretch or tear of a ligament. A ligament connects a bone to a bone. 4 major ligaments of the knee- ACL, PCL, MCL, PCL. The meniscus is a C-shaped cartilage structure that sits between the femur and tibia. One on the outside/lateral meniscus and one on the inside/medial meniscus. A wide # of treatments exists for each. If I can help, then www. Healthtap. Com/dr-clarkeholmes ...Read more

I had surgery for a medial and lateral meniscus tear 4 months ago. I still have pain when I completely straighten my leg. Scar tissue?

I had surgery for a medial and lateral meniscus tear 4 months ago. I still have pain when I completely straighten my leg. Scar tissue?

Meniscal tear postop: It could very well be scar tissue. The meniscus (or menisci-plural) may have continued to tear also. My guess is that you may have underlying arthritis, which often gets exacerbated with a knee injury. The location of your pain is also very important. I would recommend having your surgeon that did the knee scope check you out again if the pain is significant. ...Read more

Can I have chronic lateral meniscus tear or lateral meniscocapsular separation even if the MRI was normal?

Can I have chronic lateral meniscus tear or lateral meniscocapsular separation even if the MRI was normal?

It is possible: MRI results are not 100% accurate. Meniscocapsular junction tears can be hard to identify on MRI. Your symptoms and what you are experiencing as well as your clinical exam are important to determine your exact diagnosis even with an MRI. I always tell my patients as an orthopedic surgeon I treat patients, I don't treat MRI's. ...Read more

Complex entire horizontal lateral meniscus tear no swollen locking catching knee can stairs climb up down+bend now pain on off can I wait arthoscopy?

Complex entire horizontal lateral meniscus tear no swollen locking catching knee can stairs climb up down+bend now pain on off can I wait arthoscopy?

You can wait: It you're not symptomatic and that knee isn't limiting the activities that you want you do, I would recommend waiting on arthroscopy as the risks of surgery would outweigh the expected benefit. If it starts bothering you more or if it is in fact limiting your activities, then consideration of surgery is reasonable ...Read more

I have a micro fracture of the tibial plateau and a lateral meniscus tear, what to do?

I have a micro fracture of the tibial plateau and a lateral meniscus tear, what to do?

Depends: The micro-fracture will heal. Meniscal tears sometimes heal, but usually remain torn although the pain goes away. Depending on your lifestyle/activity level surgery is option not mandated. If you decline offered repair, there will likely be repeat episodes of pain/recovery. Surgery usually removes the tear and knee/activity returns essentially to normal, although traumatic arthritis eventually. ...Read more

I had arthroscopic knee surgery to fix a lateral meniscus tear. But I was doing a squat and felt popping right there could I have torn my meniscus?

Yes: Yes, it is possible that you tore your meniscus again, particularly if it was not yet fully healed. There are other possibilities as well. I would certainly let your surgeon know. ...Read more

How long is recovery time for an grade 3a tear, anterior horn, lateral meniscus. And do I need surgery.

How long is recovery time for an grade 3a tear, anterior horn, lateral meniscus. And do I need surgery.

Yes I would consider: Surgery the tear will not fix itself. Recovery depends on whether it is repaired or resected. If it is repaired (usually if you are young 25 or so and under) them recovery can be 6-8 weeks. If it is resected 2-3 weeks. ...Read more

I have a broad horizontal tear of anterior horn of right lateral meniscus extending to apex of capsular surface. VA refusing to treat. Going on 3 years. Low quality of life. What will happen if this is not surgically repaired?

I have a broad horizontal tear of anterior horn of right lateral meniscus extending to apex of capsular surface. VA refusing to treat. Going on 3 years. Low quality of life. What will happen if this is not surgically repaired?

Did they say why?: Did your doctor (s) at the VA say why they "refuse" to treat you? Do they think the risks outweigh the benefits? Have they offered physical therapy or other alternatives to surgery? Without treatment, your symptoms will continue & likely get worse. Internal damage to the knee (with or w/o surgery) can contribute to arthritis. You need answers to these questions! Please ask! Best wishes. ...Read more

Radial tear type body segment lateral meniscus. Radial type tear posterior horn lateral meniscus. Can be repaired or just snipped off?

Knee scope: Most tears of the meniscus are best treated with a partial menisectomy, or "snipping" off the torn meniscal tissue. Repairs are usually reserved for patients under the age of 30, if the tear is in the vascular zone of the meniscus. ...Read more

I had a vertical tear on medial meniscus in posterior horn and a radial tear on lateral meniscus in posterior aspect, do I need to go for surgery?

I had a vertical tear on medial meniscus in posterior horn and a radial tear on lateral meniscus in posterior aspect, do I need to go for surgery?

Possibly: Really depends on your pain and symptoms. If you are having swelling or mechanical clicking or catching you may need a scope to address the tears. You are young so the vertical tear still may be salvageable as well as the lateral tear. Want to try to preserve as much meniscus as possible in your age so would advise seeing someone fellowship trained in sports or complex arthrscopic knee techniques. ...Read more

My MRI says " chronic changes of the medial meniscus with complex tearing of the posterior horn noted. Lateral meniscus in intact". Will surgery help?

My MRI says " chronic changes of the medial meniscus with complex tearing of the posterior horn noted. Lateral meniscus in intact". Will surgery help?

Yes: If u are having medial (inside) knee pain w/ swelling and or " catching " and are in good health arthroscopic meniscal repair vs. Resection can be helpful. If you are overweight and have significant associated knee arthritis your chances of improving after the " scope" are lessened. See a board certified ors who is proficient @ knee arthroscopy. Good luck! ...Read more

The MRI suggests : complete discoid lateral meniscus with oblique tear in ant horn. Grade 2 signal involving body and posterior horn of med meniscus?

Discoid meniscus: Discoid meniscus is a developmental variant in which your meniscus (supporting cushion within the knee) is abnormally large and is predisposed to being torn. Meniscal tears may result in pain and joint locking, and may eventually lead to early osteoarthritis. You should discuss your options with an orthopedic surgeon. ...Read more

Grade 1 and grade 2 meniscal injury in anterior and posterior horns- medial meniscus. Grade 3 MI in posterior horn lateral meniscus. Knee surgery?

Grade 1 and grade 2 meniscal injury in anterior and posterior horns- medial meniscus. Grade 3 MI in posterior horn lateral meniscus. Knee surgery?

Meniscal tears: Typically grade 3 meniscal tears require surgery in young patients. Goal is preservation of the meniscus. So if it has torn in the zone where it has a good blood supply, it can be sutured and can heal. If it is torn away from the blood supply. It requires partial removal of the torn portion. All done by an experienced Orthopaedic knee surgeon. ...Read more
