Why I disagree with 2017 knee arthroscopy recommendations

Some of my patients have come to me worried after seeing media coverage of a report about knee arthroscopy, a minimally invasive surgery used to diagnose and treat knee joint conditions. The report, which was published in May 2017 in the journal BMJ, compares the effectiveness of arthroscopic surgery for treating degenerative disease with conservative treatments, such as physical therapy and medication.  

The authors reported that fewer than 15 percent of patients who had knee arthroscopy felt long-term improvement in pain or function. As such, they strongly recommend against the procedure for patients with degenerative knee problems. But I disagree with their conclusions.  

I’m not trying to be a snake oil salesman. Knee arthroscopic surgery is one of the most common orthopaedic procedures, with more than 2 million performed around the world each year. I’ve performed about 5,000 knee arthroscopies during my career, and the vast majority of my patients see improvement afterward. Many doctors in the trenches would say the same.  

While it’s true that not every patient with knee problems will benefit from arthroscopic surgery, the key is to look at each patient’s situation individually. Let me explain why I take issue with the report, how I treat patients with degenerative knee disease, and what you should consider before undergoing the procedure.

Why I disagree with the report’s knee arthroscopy recommendations  

Degenerative knee disease is an umbrella term for conditions in which the cartilage that covers the ends of the bones in the knee breaks down, causing pain, stiffness and limited mobility.  

The authors of the BMJ report define degenerative knee disease as patients older than 35 who have knee pain with or without:

  • Imaging evidence of osteoarthritis, the most common degenerative knee condition
  • Tears in the meniscus, a type of knee cartilage  
  • Locking, clicking or other mechanical symptoms
  • Symptoms that occur suddenly or have been ongoing  

The first issue with the report is that this is a huge category of people. The only patients they exclude are those whose symptoms appeared immediately after major knee trauma and have joint swelling.  

This just doesn’t make sense to me. If I have a 36-year-old patient with a meniscus tear whose X-ray shows no sign of osteoarthritis, this article seems to indicate arthroscopic knee surgery would not help. The weight of medical evidence from my experience says differently. I know repairing or removing a part of a damaged meniscus can improve pain and function.  

My second concern is how the studies were carried out. These were double blind studies, which are a high standard, but the treatments didn’t take into effect the specifics of each patient.  

The study split people with a meniscus tear and no evidence of arthritis into two treatment groups: arthroscopy and physical therapy. People with osteoarthritis also were split into arthroscopy and physical therapy groups.  

But we already know that patients who have osteoarthritis and no other conditions will not benefit from arthroscopy. However, the surgery can benefit patients with meniscus tears. The study is basically comparing apples to oranges.  

Finally, the report recommends physical therapy and medication in lieu of arthroscopy – or in severe cases total knee replacement. But many of these patients have tried physical therapy and medication such as lubricant injections, with no relief from pain. And they may be too young or not quite ready for a knee replacement.  

What are we supposed to offer these patients? They can’t do physical therapy and take anti-inflammatory medications forever. I’d hate to tell a 45-year-old patient with a meniscus tear and a little wear and tear on his knee cartilage that if physical therapy and medication doesn’t work, he must live with the pain until the day he absolutely needs a total knee replacement.

I never blanketly refuse surgery to all who have some degeneration in the knee, or those older than 35 as the article suggests. If something has occurred to the knee that is new and causing pain and it is subject to arthroscopic repair, I will always offer this option to the patient.  

We must offer these patients something, like arthroscopy, that may relieve some or all their pain. The trick is to examine each patient to determine what’s causing the problem, walk them through their options and have an honest discussion about how much pain each option may alleviate.  

How we treat degenerative knee disease

The only true cure for degenerative knee disease is knee replacement. I never treat degenerative knee disease with arthroscopy as the primary treatment, only if there is a new meniscus tear, or a tear of a degenerative meniscus that has become suddenly painful from a new tear-within-a-tear.  

But we almost always start with more conservative treatments, including:

  • Physical therapy
  • Anti-inflammatory medication such as ibuprofen
  • Injections that lubricate the joints
  • Corticosteroid injections for severe arthritis

If these treatments do not provide relief, we may discuss arthroscopic surgery. Arthroscopy can, among other things:

  • Repair anterior or posterior cruciate ligaments (ACL and PCL)
  • Repair meniscus tears  
  • Remove pieces of torn cartilage that are loose in the joint
  • Adjust a kneecap that is out of position  

I started performing knee arthroscopies in 1978, and I’ve learned who may benefit from the procedure and who won’t. I’ll be honest if I don’t think arthroscopy will help.  

In fact, I had a patient several months ago come to me for a second opinion. Her doctor had recommended arthroscopy, but I told her that due to the amount of arthritis in her knee, arthroscopy would not help and she needed a total knee replacement. She decided to do the arthroscopy with her doctor, but ended up having a knee replacement when the arthroscopy didn’t relieve the pain.  

As I said, arthroscopy will not cure or relieve pain from arthritis. However, we may recommend it to slow the arthritis down by removing loose fragments in the joint that can chip away at the cartilage.  

Questions to ask your surgeon before undergoing knee arthroscopy

We all need to be good healthcare consumers and do our due diligence when making medical decisions. Before you decide whether to have arthroscopic knee surgery, ask these questions:  

  • How many knee arthroscopies have you performed? A surgeon’s experience is crucial in knowing who may benefit and who won’t.  
  • What percent of pain will the procedure alleviate? If your doctor says you can expect 50 to 80 percent improvement in pain, you must decide whether that’s worth it. Some people say they’ll live with the pain, while others want to relieve at least some of the pain. Or your doctor may say the procedure can relieve pain for up to three years. For some people, that’s a long time to be free of knee pain. For others, it’s a sign to start considering total knee replacement.  
  • Are there alternative options? If you’re talking to a surgeon, you’ve likely already tried other conservative treatments, such as physical therapy, medications and injections. But it’s always worth asking if there’s anything else to try.  

For arthritis, knee arthroscopy is more damage control than curative. But the majority of patients who get arthroscopy for the right reasons experience relief from knee pain.   Request an appointment with an orthopedic surgeon to discuss whether arthroscopic knee surgery can help alleviate your knee pain.

Keep moving to avoid and relieve back pain

Physical activity is vital for overall health, including for a healthy spine. Most people can avoid chronic back or neck pain by maintaining an active lifestyle and making a few simple posture changes.  

But what if you’re already experiencing neck or back pain? Is it too late to make a change? For most people, it’s never too late to improve spine health.

I often see patients who come in with sudden, severe neck and back pain. It often flares up unexpectedly, such as when performing household chores. These patients often worry that they’ve damaged their spines. But in the vast majority of cases, physical therapy and sometimes non-narcotic medication will provide neck and back pain relief.

Let’s take a look at how a healthy spine works and why physical therapy is so effective to help you recuperate from and prevent future back pain.

Supporting your spine

Maintaining a healthy spine depends upon strengthening the muscles that bear its weight. The muscles around your back (often called “core” muscles) take some of the load off the spine’s lumbar vertebrae. These five large bones provide a supporting frame for the spine, but they aren’t made to hold its weight.

People experience back pain when their core muscles are too weak to support the lumbar vertebrae. If these vertebrae and the joints surrounding them bear too much weight over time, it can accelerate arthritis of the lower back, resulting in the sudden, intense pain I described earlier.    

It’s important to exercise the core muscles around your abdomen and lower back to stay strong. Many back problems are caused by inactivity and smoking.  

Inactivity and spine health

Americans spend an average of nearly eight hours per day sitting. Given that most adults have desk jobs, that number isn’t too surprising. But prolonged periods of sedentary behavior can have surprisingly severe effects on your health, so much so that this group of conditions has been given a name: “sitting disease.” Sitting disease increases your risk of obesity, high blood pressure, heart attack, cancer and more. And it also affects your spine.  

Did you know... “Americans spend an average of nearly eight hours per day sitting.”

When you’re sitting, your core muscles aren’t being worked. They sit dormant, becoming weaker the less they’re used. Making this problem worse is the fact that many people have poor sitting posture. Slouching can make it more difficult for the core muscles to bear weight and causes issues with spinal problems over time.  

Sedentary lifestyles are a common theme among my neck and back pain patients. When you’re younger, you can live an inactive life for years without back pain. But those years are silently taking a toll on your spine.  

If you must sit for most of the day, you can take proactive steps to guard against future back troubles. And if you already have back pain, these techniques are especially important to prevent it from getting worse.  

Developing healthy spine habits  

You can keep your spine healthy and avoid serious back pain by making a habit of exercising and stretching. I tell my patients they need to make core muscle exercises a part of their daily routine, just like brushing your teeth. Strengthening the core muscles helps keep your spine healthy. It’s that simple. Some exercises that I recommend include modified planks, the “superman” stretch or yoga. You may need to exercise a specific subset of core muscles depending on your condition, so ask your physical therapist or doctor which exercises you can perform to improve your spine health.  

If you sit at work, consider getting a standing desk. My patients rave about how much better their backs feel after they start using one. According to a growing body of research, reducing your sedentary time with a standing desk can also reduce your risk of cardiovascular disease and obesity, help you focus and avoid feeling tired while improving your mood at work.  

When you do sit, make sure to use proper posture. Keep your back straight and shoulders back. This posture helps maintain the natural curvature of the spine. You also should change your sitting position regularly, and get up to move around at least once per hour.

You should be on your way to a healthier spine if you stick to these habits. But if you’re still experiencing pain, or your pain begins to radiate into your arms or legs, you could have a back condition that requires more intensive treatment.  

If you have back pain, or sit for long periods of time, don’t wait for the problem to get worse. Be proactive about your spine health – you’ll feel the benefits of being flexible and active, and enjoy years free of back pain.
