Arthroscopy diagnoses several knee problems, such as a torn meniscus or a misaligned patella (kneecap). It can also repair the ligaments of the joint. There are limited risks to the procedure and the outlook is good for most patients. Your recovery time and prognosis will depend on the severity of the knee problem and the complexity of the required procedure.
Your doctor or surgeon will advise you how to prepare for your surgery. Be sure to tell them about any prescriptions, over-the-counter medications, or supplements that you’re currently taking. You may need to stop taking certain medicines, such as aspirin or ibuprofen, for weeks or days before the procedure.
You must also refrain from eating or drinking for six to 12 hours before the surgery. In some cases, your doctor may prescribe you a pain medication for any discomfort you experience after the surgery. You should fill this prescription ahead of time so that you have it ready after the procedure.

What Is Recovery Like After a Knee Arthroscopy?
This surgery isn’t very invasive. For most people, the procedure takes less than an hour depending on the specific procedure. You will likely go home on the same day for recovery. You should use an ice pack on your knee and a dressing. The ice will help reduce swelling and minimize your pain.
At home, you should have someone look after you, at least for the first day. Try to keep your leg elevated and put ice on it for a day or two to reduce swelling and pain. You’ll also need to change your dressing. Your doctor or surgeon will tell you when to do these things and for how long. You will probably need to see your surgeon for a follow-up appointment a few days after the procedure.
