Arthroscopy is a modern surgical technique that allows doctors to look inside your joints through tiny incisions, diagnose problems, and often repair them during the same procedure—all while causing less pain and promoting faster recovery than traditional open surgery.
What Is Arthroscopy?
Arthroscopy is a type of minimally invasive surgery, which means it uses very small incisions instead of large cuts to examine and treat problems inside your joints. The word arthroscopy comes from two Greek words: “arthro” meaning joint, and “skopein” meaning to look. So it literally means “to look within the joint.”[1]
During this procedure, an orthopaedic surgeon—a doctor who specializes in treating bones, joints, and muscles—inserts a special tool called an arthroscope into your joint. This instrument is a thin, pencil-sized tube that contains a small camera and a light source. The camera sends live video images to a monitor in the operating room, allowing the surgeon to see inside your joint in great detail without making a large incision.[2]
The surgeon makes an incision about the size of a buttonhole—roughly half an inch or less—to insert the arthroscope. If treatment is needed, the surgeon creates one or more additional small incisions, about the size of a dime, to insert narrow surgical instruments. These long, thin tools allow the surgeon to operate while watching the procedure on the video screen.[3]
Joints That Can Be Examined
Arthroscopy can be performed on many different joints throughout your body. The knee is the most commonly treated joint with this technique, but the procedure is also frequently used on other major joints. Surgeons regularly perform arthroscopy on the shoulder, ankle, hip, elbow, and wrist.[1]
Each type of joint may require slightly different approaches, but the basic principle remains the same—using a small camera to see inside the joint and small instruments to fix problems. The choice of which joint needs arthroscopy depends entirely on where you’re experiencing symptoms and what your doctor finds during examination and imaging tests.[4]
Conditions Treated With Arthroscopy
Arthroscopy helps doctors diagnose and treat a wide variety of joint problems. Sometimes, doctors recommend this procedure when X-rays and other imaging studies like MRI scans haven’t provided clear answers about what’s causing your joint pain or dysfunction.[1]
Common conditions that can be treated with arthroscopy include torn cartilage, such as meniscus tears in the knee or labral tears in the shoulder or hip. The meniscus is a wedge-shaped piece of cartilage that acts as a shock absorber between your thigh bone and shin bone. When this tissue tears, it can cause pain, swelling, and difficulty moving your knee.[2]
Ligament injuries are another common reason for arthroscopy. Torn ligaments, including ACL tears (anterior cruciate ligament tears) in the knee, ankle sprains, and wrist sprains, can often be repaired arthroscopically. Ligaments are strong bands of tissue that connect bones to each other and help stabilize your joints.[2]
The procedure is also used to treat joint impingement, a condition where bones or soft tissues in the joint rub against each other abnormally, causing pain and restricted movement. This can occur in the ankle, shoulder, or hip. Joint instability, where a joint feels loose or gives way unexpectedly, can also be addressed through arthroscopy.[2]
Other conditions commonly treated include inflamed joint linings, loose bone or cartilage fragments floating in the joint, scarring within joints, damaged or worn cartilage surfaces, nerve compression syndromes like carpal tunnel syndrome in the wrist, and synovitis—inflammation of the tissue lining the joint, which is often an early sign of rheumatoid arthritis.[3]
How the Procedure Works
Understanding what happens during arthroscopy can help reduce anxiety about the procedure. Most arthroscopic surgeries are performed as outpatient procedures, meaning you can go home the same day rather than staying overnight in the hospital.[2]
Before the surgery begins, you’ll receive anesthesia. Depending on the joint being treated and your overall health, you may have a local anesthetic that numbs just the area around your joint while you stay awake, or you may have general anesthesia that puts you to sleep for the entire procedure. Some patients receive a spinal anesthetic, which numbs the lower half of the body.[5]
Once the anesthesia takes effect, the surgeon positions your joint properly for the procedure. They may use a holding device to keep the joint stable during surgery. The surgeon then makes the first small incision and inserts the arthroscope into your joint.[2]
To create more room to see and work inside the joint, the surgeon fills the joint space with a sterile salt water solution called saline. This fluid expands the joint, making it easier to examine structures and move instruments around safely.[2]
As the arthroscope projects magnified images onto a video monitor, the surgeon carefully examines all the structures inside your joint. If problems are found that can be repaired, the surgeon makes additional small incisions to insert specialized surgical tools. Depending on your specific condition, the surgeon might remove damaged tissue or loose fragments, repair or reinforce torn tissues or broken bones, release a compressed nerve, or reshape and adjust misaligned bones in the joint.[2]
Most arthroscopy procedures take between one and two hours to complete. When the surgery is finished, the surgeon removes all instruments, drains the saline from the joint, and closes the small incisions with stitches or surgical tape.[2]
Preparing for Arthroscopy
Proper preparation before your arthroscopic surgery can significantly impact your recovery experience. In the weeks leading up to your procedure, your doctor will conduct a thorough evaluation that includes a physical examination and imaging studies. Your doctor may order X-rays, MRI scans, CT scans, or blood tests to help plan your surgery and ensure you’re healthy enough for the procedure.[5]
You’ll need to discuss all your current medications with your doctor. Some medications, especially blood thinners like aspirin, certain anti-inflammatory drugs, and even some herbal supplements, must be stopped several days before surgery because they can cause excessive bleeding during and after the procedure. Never stop taking any medication without your doctor’s specific instructions.[16]
If you smoke, your doctor will strongly encourage you to quit at least two weeks before your procedure. Smoking interferes with healing, reduces blood flow to tissues, and increases your risk of complications after surgery.[2]
Because arthroscopy requires anesthesia, you won’t be able to eat or drink anything after midnight the night before your surgery. This fasting requirement ensures your stomach is empty, which reduces the risk of vomiting and aspiration—breathing stomach contents into your lungs—during anesthesia.[16]
You must arrange for someone to drive you home after the procedure. The effects of anesthesia can remain in your system for up to 24 hours, making it unsafe for you to drive or operate machinery. It’s also recommended that you have someone stay with you for at least the first night after surgery to help with basic tasks and monitor your condition.[16]
Preparing your home before surgery is equally important. Remove tripping hazards like loose rugs and electrical cords. Create a comfortable recovery space on your main floor if you have stairs, as climbing may be difficult initially. Stock up on ice packs, prepare some meals in advance, and gather comfortable, loose-fitting clothing that will fit easily over bandages. Place items you’ll need frequently within easy reach so you don’t have to move around more than necessary.[2]
Recovery and Healing
After arthroscopy, you’ll spend one to two hours in a recovery room as you wake up from anesthesia. Healthcare providers will monitor your vital signs and check your surgical site before you’re allowed to go home.[2]
One of the biggest advantages of arthroscopic surgery over traditional open surgery is faster recovery. Because the incisions are so small, most patients experience less pain, minimal blood loss and scarring, and a quicker return to normal activities. However, the exact recovery time varies depending on which joint was treated, what procedures were performed, and your overall health.[2]
In the first few days after surgery, you’ll likely feel tired and notice swelling around your joint. The skin near your incisions may appear discolored or bruised, which is completely normal. Keeping your joint elevated above the level of your heart helps reduce swelling and pain. Use pillows to prop up your leg or arm comfortably.[14]
Applying ice packs to the surgical area is an effective way to manage swelling and discomfort. Most doctors recommend icing for 15 to 20 minutes at a time, three to four times per day, until the swelling decreases. Always place a towel between the ice pack and your skin to prevent ice burns.[6]
Your doctor will prescribe pain medication to help you manage discomfort during the first few days. Take these medications exactly as directed. If you experience nausea from pain medication, try taking it with food. If problems persist, contact your doctor about switching to a different medication.[14]
Wound care is critical for preventing infection. If you have a dressing over your incisions, keep it clean and dry. You may be allowed to remove it 48 to 72 hours after surgery. Most patients can shower within two to three days after the procedure, cleaning the incisions gently with regular soap and water. However, you should avoid taking baths or soaking the surgical area until your doctor gives permission.[14]
If you have strips of tape on your incisions, leave them in place for about a week or until they fall off on their own. Watch for signs of infection, including increased redness, warmth, swelling, discharge from the incisions, fever, or worsening pain. Contact your doctor immediately if any of these symptoms develop.[5]
Most people need about six weeks to recover fully from arthroscopy, though this timeline can be shorter or longer depending on the complexity of your surgery. If your surgeon repaired damaged tissue rather than just removing it, recovery typically takes longer. You may need to limit your activities until your joint strength and range of motion return to normal.[14]
Return to work depends on your job type. If you have a desk job that doesn’t require physical labor, you might return within a few days. However, if your work involves lifting, standing for long periods, or significant physical activity, you may need several weeks to a few months before you can safely resume your duties.[14]
Physical Therapy and Rehabilitation
Physical therapy is a cornerstone of recovery after arthroscopy. Whether you had a tendon repair, ligament reconstruction, or removal of damaged tissue, rehabilitation exercises are essential for restoring optimal joint function. Your doctor may have you start gentle exercises very soon after surgery to prevent stiffness and promote healing.[17]
A physical therapist will create a customized rehabilitation plan based on your specific surgery, age, overall health, and activity goals. Initially, you’ll work with the therapist several times a week, learning exercises and stretches designed to gradually restore strength, flexibility, and range of motion in your joint.[17]
Early exercises often include gentle movements like rotating, bending, and straightening the affected limb. As healing progresses, the intensity and complexity of exercises increase. Eventually, many of these exercises can be performed at home between therapy sessions.[6]
Consistency with your physical therapy program is crucial. While progress may seem slow at times, sticking with your rehabilitation plan is the fastest route to full recovery. Skipping exercises or pushing too hard too soon can both delay healing or cause new injuries.[17]
Depending on your surgery, you may need to use assistive devices like crutches, a sling, or a brace during the initial recovery period. Your healthcare team will instruct you on how long to use these devices and when it’s safe to begin bearing full weight on your joint or using it normally.[5]
Risks and Complications
Arthroscopy is considered a very safe procedure, and serious complications are uncommon. However, like any surgery, it does carry some risks that patients should understand before the procedure.[1]
Infection is a risk with any invasive surgery. However, because arthroscopy uses such small incisions, the risk of infection is significantly lower than with traditional open surgery that requires large cuts. Despite this lower risk, it’s important to watch for signs of infection and follow all wound care instructions carefully.[1]
Tissue or nerve damage can occur during arthroscopy. The placement and movement of instruments inside the joint could potentially damage the joint’s structures, nearby nerves, or blood vessels. Surgeons take great care to avoid these complications, but they remain a possibility.[1]
Blood clots are a rare but serious complication. Procedures lasting longer than an hour slightly increase the risk of blood clots developing in the legs. These clots can be dangerous if they break free and travel to the lungs. Your surgical team may recommend specific measures to reduce this risk, such as wearing compression stockings or taking blood-thinning medications.[1]
Other potential complications include excessive bleeding during or after surgery, stiffness in the joint, numbness near the incision sites, and in very rare cases, chronic pain. The specific risks vary somewhat depending on which joint is being treated and what procedures are performed.[6]
General anesthesia also carries its own small set of risks, though serious reactions are extremely rare. Some patients experience a sore throat after surgery from the breathing tube used during general anesthesia. Nausea and grogginess are common but temporary side effects.[6]
Benefits Compared to Traditional Surgery
The primary advantage of arthroscopy over traditional open joint surgery is that it’s minimally invasive. This approach offers multiple benefits that improve the patient experience and outcomes.[2]
Smaller incisions mean less damage to surrounding muscles and tissues. This results in less postoperative pain, which means patients often need less pain medication and experience more comfort during recovery. The tiny incisions also create minimal scarring, which many patients appreciate for both functional and cosmetic reasons.[2]
Blood loss during arthroscopy is typically minimal compared to open surgery. Less blood loss means fewer risks during surgery and faster recovery afterward. The risk of infection is also significantly lower with arthroscopy because there’s less exposure of internal tissues to the environment.[2]
Perhaps most importantly for many patients, arthroscopy generally allows for a faster return to normal activities. Joint stiffness is typically less severe, and the healing process is accelerated. Many people can resume light daily activities within days and return to full function weeks or even months sooner than they would after traditional open surgery.[2]
Lifestyle and Dietary Considerations
Making specific lifestyle changes during your recovery can significantly speed up healing and improve your overall outcome. Taking a holistic approach to recovery often leads to better results.[17]
Nutrition plays a vital role in healing after surgery. A balanced diet rich in protein, vitamins, and minerals provides your body with the building blocks it needs to repair damaged tissues. Focus on foods that reduce inflammation, such as leafy green vegetables, fatty fish like salmon, nuts, and fruits rich in antioxidants.[17]
Staying well-hydrated is equally important. Water supports all of your body’s healing processes and helps maintain joint lubrication. Aim to drink plenty of fluids throughout the day unless your doctor has given you different instructions.[14]
Avoid substances that can slow healing, including excessive alcohol, tobacco, and highly processed foods. These can interfere with your body’s natural healing mechanisms and may increase inflammation or slow tissue repair.[17]
The mental and emotional aspects of recovery are often overlooked but are equally important. Frustration, anxiety, stress, and impatience are common feelings during recovery, especially if progress seems slow. Managing your mental health through mindfulness activities, meditation, gentle stretching (as approved by your doctor), reading, or other calming hobbies can make the recovery process more bearable.[17]
Adequate rest and sleep are critical for healing. Your body does much of its repair work while you sleep, so prioritize getting enough rest each night. Listen to your body—if you feel tired, rest rather than pushing through exhaustion.[14]
When to Seek Medical Attention
While most arthroscopy recoveries proceed smoothly, it’s important to know when to contact your healthcare provider. Some symptoms require immediate attention, while others should be discussed at your next scheduled follow-up appointment.[5]
Call your doctor immediately if you develop a fever, as this could indicate an infection. Increasing pain that doesn’t improve with prescribed medication or that gets significantly worse is also concerning. Sudden, severe swelling or redness spreading from the surgical site should be evaluated promptly.[14]
Any discharge from your incisions, especially if it’s thick, cloudy, or has an unpleasant odor, warrants a call to your doctor. New numbness, tingling, or weakness in the affected limb that wasn’t present immediately after surgery could indicate a problem that needs assessment.[5]
If you experience chest pain, difficulty breathing, or pain and swelling in your calf, seek emergency medical attention immediately. These could be signs of a blood clot that has traveled to your lungs, which is a medical emergency.[14]
Trust your instincts—if something doesn’t feel right or you’re concerned about any aspect of your recovery, don’t hesitate to contact your healthcare team. They would rather answer questions and provide reassurance than have you worry unnecessarily or miss early warning signs of complications.[5]
