What Are the Different Types of Knee Surgery?

Most knee surgeries are done by making a few smallcutsin the knee. The surgeon inserts tools and a small camera into these cuts to observe what needs to be done. This method of looking at joints, like the knee joint, is calledarthroscopy.

The most common types ofknee painsurgery include:

• Knee replacementsurgery
• ACL surgery
• Meniscussurgeries

Knee replacement surgery is also called arthroplasty. Your doctor will recommend this surgery if you have severearthritisor were seriously injured.

Both full and partial knee replacement surgeries are available. In partial replacement surgeries, only the damaged parts of your knee joint are removed and replaced with artificial parts made ofplasticor metal.

In a full replacement surgery, all parts of your knee joint and cap are replaced with metal and plastic parts. The goal of this surgery is to create new surfaces so your knee no longer hurts when its different parts touch. Recovery time is different for each person. Your doctor will order physical therapy until you have regained muscle strength and acceptable range of motion.

The surgery has risks.Blood clotscan develop as well as infections. There's also the chance that the surgery will not fix your kneepain.

Revision knee replacements are another version of this surgery. Knee replacement surgeries usually wear out after 15 to 20 years. In this case, you’ll have to repeat the surgery — but this time your original replacement parts will be replaced.

ACL injuries are very common — particularly in sports. Surgery is not needed for slight tears, only when your entire ligament needs to be replaced. The replacement is woven through the knee joint and attached to the upper and lower leg bones.

真正的组织是用于替换。有时this will come from another part of your body, which will make the surgery take more time. At other times a donated tissue is used.

It can take up to six months for you to recover enough to resume normal activities, such as playing sports.

The meniscus is cartilage that acts as ashockabsorber in your knee. You can easily tear it by twisting your knee. Smaller tears to the outer parts of the meniscus will heal on their own and don’t always require surgery. When you damage your meniscus symptoms can include:

• Pain
• Swelling
• Problems moving your joint from stuck pieces of cartilage

Your surgeons will decide the exact type of surgery that you need when they see the damage inside of your knee using a small camera. Meniscus repair is the best option, but can only be done when the damage is in a part of the meniscus that has a lot of blood flow. The portion of the meniscus that has torn will be reattached.Sutures, a type of stitch, or specialized meniscus repair devices are used to reattach the piece.

A meniscectomy is a related surgery, but, in this case, the damaged pieces of the meniscus are completely removed. Your surgeon will only choose this option when repair is not possible. Patients who have removal surgeries have much greater rates of arthritis than those who have their meniscus repaired.

You may need a specialized knee surgery that's less common than the ones discussed above. Some examples include knee osteotomies and knee plica surgeries.

Knee osteotomies

Knee osteotomies are sometimes done when only one side of your knee is affected by arthritis. In this surgery, your bones are rearranged in order to shift the way that your weight lands on your knee. Your surgeon will add or remove pieces to your upper and lower leg bones in a way that suits your body.

Knee plica surgeries

Knee plica surgeries are most often performed alongside other knee surgeries. The plica is a smooth, elastic tissue that slides around on the end of the upper leg bone — on top of the knee. When this plica is irritated, you’ll experience symptoms that are similar to those from atorn meniscus.

Your doctor won't typically diagnose this until they've been able to look inside your knee with a camera. The plica can either be removed entirely or divided into parts and only partially removed. It's not replaced. Most patients don't experience any negative symptoms after the plica is removed.

The particular knee surgery that's right for you will depend entirely on your injury or symptoms. It’s important to talk to your doctor about your options when your knee pain is too intense or doesn’t go away.
