Knee arthroscopy is a surgical procedure where a surgeon uses a small camera (arthroscope) inserted through tiny cuts in your knee to diagnose and treat various knee problems. This article explains what you can expect on the day of your surgery.
Key facts
Yes, knee arthroscopy is one of the most common orthopedic surgeries performed worldwide.
It affects people of all ages who have knee injuries or conditions that do not get better with rest, physical therapy, or other non-surgical treatments.
Before the day of surgery, your doctor will have diagnosed the need for arthroscopy. This usually starts with a physical exam where they check your knee’s movement, stability, and tenderness. They will ask about your symptoms and any injuries.
On the day of surgery, you will arrive at the hospital or surgical center. You will be asked not to eat or drink anything for several hours before the procedure (usually from midnight the night before). You will meet the anesthesiologist, who will discuss the type of anesthesia (often general or regional). The surgery itself usually takes 30–60 minutes. Afterward, you will go to a recovery room where nurses will monitor you until you are awake and comfortable enough to go home. You will need someone to drive you home.
Knee arthroscopy is a treatment option when other methods like rest, physical therapy, and pain relief have not worked. During the procedure, the surgeon can repair torn cartilage, remove loose pieces, or smooth rough surfaces. Treatment does not stop with surgery – aftercare and rehabilitation are key to a full recovery.
Your surgeon may prescribe pain relief medication to take after the procedure. You can also use over-the-counter pain relievers like paracetamol or ibuprofen, but always check with your doctor or pharmacist before taking any medicine, especially if you have other health conditions or take other medications. In hospital, you might receive a local anesthetic injection to numb the knee.
For the first few days after surgery, you will need to take it easy. Use crutches if your surgeon recommends them. Most people can return to desk work within a week, but avoid driving until you can safely operate the pedals (usually 1–2 weeks). Follow your physiotherapy plan closely to regain strength and mobility.
Eat a healthy balanced diet rich in protein (to help tissue healing) and vitamin C (for wound healing). Drink plenty of water. For exercise, begin with the simple leg exercises your physiotherapist gives you – like ankle pumps and straight leg raises. As you recover, you can gradually increase activity, but always follow your surgeon’s timeline for returning to sports or high-impact activities.
Not all knee problems that lead to arthroscopy can be prevented, but you can reduce your risk by maintaining a healthy weight, strengthening the muscles around your knee (especially quadriceps and hamstrings), and using proper technique in sports and exercise. Wearing appropriate footwear and warming up before activity also help.
The outlook for most people who have knee arthroscopy is very good. Many return to their usual activities within a few weeks and experience significant pain relief. Full recovery may take a few months, especially if you follow your rehabilitation plan. While some knee conditions are not curable, surgery can greatly improve your quality of life. Your surgeon will give you a realistic idea of what to expect based on your specific situation.

Surgery is considered when non-surgical treatments have not helped and the knee problem is causing significant pain, instability, or difficulty with daily activities. Your doctor will discuss the risks and benefits with you.
It is normal to feel anxious or frustrated during recovery, especially if progress feels slow. You may worry about the surgery outcome or fear re-injury. Talk to your healthcare team about any concerns. If feelings of sadness or worry last longer than a few weeks, reach out to your doctor or a mental health professional. In a crisis, call your local emergency number or a crisis helpline.
