If you play sports, you might twist your knee while running or jumping and feel sudden pain. Or maybe you twist your knee doing a simple chore at home and hear a loud pop.
Now your knee is swollen, hard to bend or straighten, and feels like it is catching inside. These signs often point to an injury in the meniscus, which is a piece of shock-absorbing cartilage inside your knee.
- The meniscus is a C-shaped cushion that protects your knee bones.
- Meniscus surgery fixes or removes torn cartilage to relieve pain and restore motion.
- Doctors often use a keyhole method called knee arthroscopy.
- Recovery time ranges from six weeks to several months depending on the repair type.
- Physical therapy is essential to rebuild strength and stability in your leg.

What is Meniscus Surgery in Simple Terms?
Let us look at your knee joint first. Between your thigh bone and shin bone, you have two C-shaped pieces of cartilage called the meniscus.
They act like shock absorbers in a car. They cushion the joint when you walk, run, or jump, keeping your bones from grinding together.
When you tear your meniscus, you may face severe pain, swelling, knee locking, or instability. If rest, medicine, and physical therapy do not help, your doctor may suggest surgery.
This surgery repairs the torn meniscus part or removes the damaged piece so your knee can move smoothly again.
How to Prepare for Your Surgery
Getting ready for your procedure involves a few standard steps to ensure your safety and comfort.
Your doctor will guide you through the necessary pre-surgery medical checks.
| Medical Test | What It Means for You |
|---|---|
| Physical exam | Your doctor checks your knee and overall health status. |
| Blood tests | Checks your blood counts and looks for any hidden infections. |
| EKG | Measures your heart rhythm to ensure it is healthy for anesthesia. |
| Chest X-ray | Examines your lungs and heart condition before surgery. |
| Knee imaging (X-ray and MRI) | Shows bone structure and gives a clear view of the meniscus tear. |
Other vital preparation steps include:
- Tell your doctor about all medicines, vitamins, and herbal supplements you take. They may ask you to stop blood thinners before surgery.
- Follow fasting rules carefully. You will usually need to stop eating and drinking for about twelve hours prior to the procedure.
- Arrange for a trusted family member or friend to drive you home afterward, as you cannot drive right away.
What Happens During the Surgery?
On surgery day, an anesthesia specialist will keep you comfortable and pain-free. They may use general anesthesia to help you sleep or regional anesthesia to numb your lower body while you stay relaxed.
Doctors usually perform this operation using a keyhole technique. They make small cuts around your knee and insert a tiny camera along with fine tools.
This approach is called a knee arthroscopy. It leaves smaller scars and helps you heal faster.
| Surgery Type | What the Doctor Does / Best Suited For |
|---|---|
| Meniscus repair | What the Doctor Does: Sews the torn edges together using special medical thread that dissolves over time. Best Suited For: Tears located in areas with good blood supply where healing is likely. |
| Partial meniscectomy | What the Doctor Does: Trims away the damaged, loose cartilage and smooths out the remaining healthy edge. Best Suited For: Severe tears where the ragged tissue cannot be sewn back together. |
| Meniscus replacement | What the Doctor Does: Removes the destroyed meniscus and implants donor tissue. Best Suited For: Younger patients with severe damage and no major arthritis. |
How Long Does Surgery Take and What Happens Next?
Most meniscus surgeries take about one hour. The exact duration depends on the tear severity and whether you need extra repairs like ligament fixing.
This is often an outpatient procedure. You can go home on the same day after waking up in the recovery room and meeting discharge criteria.
