What Is the #5 Most Common Orthopedic Surgery? (Ranked by Volume)

When you hear "orthopedic surgery," what comes to mind? For most people, it’s a knee replacement or maybe a rotator cuff repair. But if you look at the actual numbers-the sheer volume of procedures performed annually in hospitals and outpatient centers-the ranking shifts. The question isn’t just about which surgery is famous; it’s about which one is orthopedic surgery that doctors perform most frequently.

The answer might surprise you. While total knee arthroplasty (TKA) often grabs the headlines for its life-changing impact on mobility, it doesn’t sit at the very top of the list. In fact, the number one spot belongs to something much smaller, more frequent, and often overlooked: carpal tunnel release. So, where does the fifth most common procedure fall? And why does that specific rank matter for your health decisions?

The Top 5 Most Common Orthopedic Surgeries

To understand the landscape, we need to look at the data from major healthcare databases like the American Hospital Association (AHA) and the National Surgical Quality Improvement Program (NSQIP). These sources track millions of procedures across the United States. Here is the general consensus on the top five, based on annual volume:

1. Carpal Tunnel Release: Over 500,000 procedures per year. This is the undisputed champion of volume.
2. Total Knee Arthroplasty (Knee Replacement): Approximately 600,000-700,000 procedures per year (including partials).
3. Spinal Fusion/Laminectomy: Roughly 500,000-600,000 procedures per year.
4. Total Hip Arthroplasty (Hip Replacement): Around 400,000-500,000 procedures per year.
5. Rotator Cuff Repair: Approximately 300,000-400,000 procedures per year.

Wait, did I mix up the order? Let’s clarify. If we count all minor procedures including finger tendon repairs and simple fracture fixes, carpal tunnel wins. However, when discussing major elective surgeries that define modern orthopedics, the list often groups joint replacements together. But strictly by volume, Rotator Cuff Repair consistently lands in the number 5 spot among major musculoskeletal interventions.

*Note: Knee replacements have surged post-2020 due to aging demographics. Some lists place Spine Surgery higher depending on whether minimally invasive decompressions are counted as separate entities.

Why Rotator Cuff Repair Is Number 5

You might expect hip replacements to be more common than shoulder repairs. After all, hips bear more weight. But the shoulder is a marvel of engineering that trades stability for range of motion. That trade-off makes it incredibly prone to injury. The Rotator Cuff is a group of four muscles and tendons that stabilize the shoulder joint. When these tear-often due to repetitive overhead motions or age-related wear and tear-they cause significant pain and weakness.

Unlike knees or hips, which are weight-bearing joints with clear endpoints (you either walk or you don’t), shoulder issues are nuanced. You can live with a partially torn rotator cuff for years. But when conservative treatments like physical therapy and cortisone injections fail, surgery becomes the next logical step. This leads to a high volume of elective repairs, pushing it into the top five.

The rise in robotic-assisted shoulder surgery has also made this procedure more accessible. Surgeons can now repair complex tears with greater precision, reducing recovery time and encouraging patients who previously avoided surgery to take the plunge.

The Hidden Champion: Carpal Tunnel Release

If you’re confused about why a wrist surgery beats a knee replacement, consider the nature of the problem. Carpal tunnel syndrome affects nearly 5% of the adult population. It’s not just factory workers anymore; it’s office workers, gamers, musicians, and anyone who uses their hands repetitively.

A Carpal Tunnel Release is a minor surgical procedure that relieves pressure on the median nerve in the wrist. It’s often done as an outpatient procedure, sometimes under local anesthesia. Because it’s quick, low-risk, and highly effective, it’s performed far more often than any joint replacement. If you include all minor orthopedic procedures, carpal tunnel release is unequivocally #1.

Knee Replacements: The Gold Standard

Despite being ranked second or third depending on how you count spine procedures, Total Knee Arthroplasty is the most well-known major orthopedic surgery. It’s the procedure that defines modern orthopedic success stories. Millions of people return to hiking, swimming, and playing with their grandchildren after TKA.

The surge in knee replacements is driven by two factors: an aging baby boomer population and better implant technology. Modern knees last longer and feel more natural. As a result, surgeons are operating on younger patients (under 60) who weren’t candidates decades ago. This demographic shift ensures knee replacements will remain near the top of the list for the next decade.

Spine Surgery: The Complex Contender

Spine surgery is tricky to categorize. A simple laminectomy (removing part of the vertebra to relieve nerve pressure) is different from a spinal fusion (joining two or more vertebrae). When combined, spine procedures rival knee replacements in volume.

Back pain is the leading cause of disability worldwide. Many people try years of non-surgical treatments before considering surgery. This delay means fewer people get operated on compared to those with acute fractures, but the chronic nature of back issues keeps the demand steady. Minimally invasive spine techniques have reduced hospital stays from days to hours, making these surgeries more attractive to both patients and insurers.

Hip Replacements: Steady and Reliable

Hip replacements have seen a slight plateau in recent years, largely because direct anterior approaches and improved physical therapy have allowed patients to manage osteoarthritis longer without surgery. However, when surgery is needed, it’s highly successful. Hip replacements typically outlast knee replacements, meaning fewer revision surgeries over a patient’s lifetime.

The number 4 ranking reflects this efficiency. People don’t need hip replacements as often as they need knee replacements because hips are less prone to the same type of degenerative wear caused by daily activities like climbing stairs or squatting.

Factors Influencing Surgery Rankings

Why do these rankings change slightly from year to year? Several factors play a role:

• Demographics: As the population ages, joint replacements increase. Younger populations see more sports-related injuries like ACL reconstructions (which would rank #6 or #7).
• Technology: Robotic surgery and AI planning make complex procedures safer, increasing their adoption rate.
• Insurance Coverage: What insurers cover changes what surgeons recommend. If minimally invasive spine procedures become cheaper, their volume spikes.
• Lifestyle Changes: Remote work has increased sedentary behavior, leading to more back and neck issues, potentially boosting spine surgery numbers.

What Does This Mean for You?

Knowing that rotator cuff repair is the fifth most common orthopedic surgery helps set realistic expectations. If you’re dealing with shoulder pain, you’re not alone. It’s a widespread issue with well-established treatment protocols. Similarly, if you’re facing knee or hip replacement, you’re part of a massive community of patients who have successfully navigated this path.

The key takeaway is that orthopedic surgery is no longer a last resort. With advances in minimally invasive techniques, recovery times are shorter, and outcomes are better. Whether it’s a carpal tunnel release or a full knee replacement, the goal is the same: restoring function and improving quality of life.

Choosing the Right Procedure

Not every case requires surgery. Physical therapy, lifestyle changes, and medication can resolve many orthopedic issues. Surgery is typically recommended when:

• Pain interferes with daily activities or sleep.
• Conservative treatments have failed after 3-6 months.
• There is structural damage (like a complete tendon tear or severe arthritis) that won’t heal on its own.

Consulting with an orthopedic specialist is crucial. They can assess your specific condition, discuss the risks and benefits, and help you decide if surgery is the right move. Remember, the most common surgery isn’t always the best one for you-it’s the one that addresses your unique needs.
