A cortisone shot can help decrease the inflammation and pain caused by a torn meniscus. A cortisone shot usually does not help in healing of the meniscus and, hence, does not improve any mechanical symptoms. If a meniscus is repairable, then a cortisone shot is not preferred as it may impair healing of the meniscus.
An effective, long-lasting treatment has widely been sought after. Intra-articular corticosteroid injections have been among the methods of controlling pain for more than 60 years. However, such injections tend to produce short-lasting results, with profound effects lasting an average of up to 4 weeks.
There are two main injection options; steroid or hyaluronic acid injections. Steroid is a strong anti-inflammatory and is deposited directly into your knee joint using ultrasound guidance. This ensures the drug is deposited in the correct place.
While injections temporarily reduce pain, they will not help heal the meniscus tear. Researchers have been developing stem-cell therapies that may help heal the injured tissue.
AM3101 is an injectable drug being developed as a therapy to reduce the frequency of complications and morbidities associated with failed meniscal repair surgery. Meniscal tears, particularly in the portion of the tissue lacking sufficient blood supply, are often irreparable and require removal of the disease tissue.
In the case of meniscus tears, some people think the injury will heal over time on its own. But the truth is that there are different types of meniscus tears — and some tears won't heal without treatment. If your tear is on the outer one-third of the meniscus, it may heal on its own or be repaired surgically.
Meniscus tears are the most frequently treated knee injuries. Recovery will take about 6 to 8 weeks if your meniscus tear is treated conservatively, without surgery. If your symptoms persist after 3 months or your symptoms become significant, your doctor may recommend surgery to repair the tear.
The injection consists of two medications: Cortisone (a steroid) and Marcaine (a numbing agent). It is recommended that you refrain from any high level activities using your knee for approximately 48 hours. Routine activities including walking are permitted.
Continuing to walk on the affected leg can aggravate your symptoms, making pain and stiffness worse in as little as a few days. Plus, suffering a torn meniscus may also increase your risk of complications, like developing osteoarthritis in that knee.
Spontaneous healing is uncommon in adults, but may occur in some cases. Safe strengthening activities such as cycling which avoid twisting and hyperflexion. Optional anti-inflammatory medication (Diclofenac/Voltaren or Ibuprofen/Motrin) for 1-2 weeks. Arthroscopic surgery to trim the damaged meniscus.
A horizontal meniscus tear is one of the easiest types of tears to repair in the knee. Rather than removing the portion of the meniscus that is damaged, the surgeon will try to sew together the circumferential fibers of the meniscus back together.
Meniscus tears hurt because they upset the lining or the synovium of the knee. The synovium has a lot of nerves in it and this synovium will cause significant pain, and swelling when it is irritated.
The most common side effect is intense pain and swelling in the joint where the injection was given. This usually gets better after a day or two. You may also get some bruising where the injection was given. This should go away after a few days.
There's concern that repeated cortisone shots might damage the cartilage within a joint. So doctors typically limit the number of cortisone shots into a joint. In general, you shouldn't get cortisone injections more often than every six weeks and usually not more than three or four times a year.
Generally, if the first shot doesn't work, we may inject the same area again after 6-8 weeks. However, if a second shot doesn't work, we don't recommend a third shot. But, you can have multiple cortisone shots in different parts of your body.
If you experience a post-injection steroid flare wait until it has passed prior to driving again (typically a few days after the injection). Ensure you can perform an emergency brake before starting to drive again. Contact your insurance company if you have any concerns.
A: The brace needs to be worn during the 4 to 6 week period after your injection while you're weight bearing, including and especially during exercise.
Hyaluronic acid injections
Hyaluronic acid (HA) injections often are used when corticosteroid injections don't work. But they usually are approved only for use in the knee. In some instances, doctors consider HA injections first if you don't have obvious signs of inflammation.
If your meniscus is torn and simply won't heal, the question is whether a surgeon should fix it or take part of it out. “Most meniscus tears are not repairable because of the pattern of the tear. Only the outer third of the meniscus has a blood supply and will heal reliably,” said Joshua J.
A torn meniscus is certainly not life threatening. Once treated, the knee will usually function normally for many years. A meniscal tear that catches, locks the knee, or produces swelling on a frequent or chronic basis should be removed or repaired before it damages the articular (gliding) cartilage in the knee.
You will have a physical examination to find out if you have a torn meniscus and to rule out other knee injuries. Your doctor will check both knees for tenderness, range of motion, and knee stability. X-rays are usually done. Based on your symptoms and the physical examination, your doctor may diagnose a meniscus tear.
