Femoral nerve block. This is another type of regional anesthesia. The pain medicine is injected around the nerve in your groin. You will be asleep during the operation. This type of anesthesia will block out pain so that you need less general anesthesia.
A cuff-like device may be put around your thigh to help control bleeding during the procedure.
The surgeon will make two or three small cuts around your knee. Salt water (saline) will be pumped into your knee to inflate the knee.
A narrow tube with a tiny camera on the end will be inserted through one of the cuts. The camera is attached to a video monitor that lets the surgeon see inside the knee.
The surgeon may put other small surgery tools inside your knee through the other cuts. The surgeon will then fix or remove the problem in your knee.
At the end of your surgery, the saline will be drained from your knee. The surgeon will close your cuts with sutures (stitches) and cover them with a dressing. Many surgeons take pictures of the procedure from the video monitor, You may be able to view these pictures after the operation so that you can see what was done.
Why the Procedure Is Performed
Arthroscopy may be recommended for these knee problems:
Torn meniscus. Meniscus is cartilage that cushions the space between the bones in the knee. Surgery is done to repair or remove it.
Full recovery after knee arthroscopy will depend on what type of problem was treated.
Problems such as a torn meniscus, broken cartilage, Baker's cyst, and problems with the synovium are often easily fixed. Many people stay active after these surgeries.
Recovery from simple procedures is fast in most cases. You may need to use crutches for a while after some types of surgery. Your provider may also prescribe pain medicine.
Recovery will take longer if you have had a more complex procedure. If parts of your knee have been repaired or rebuilt, you may not be able to walk without crutches or a knee brace for several weeks. Full recovery may take several months to a year.
If you also have arthritis in your knee, you will still have arthritis symptoms after surgery to repair other damage to your knee.
