Common Misconceptions: Meniscus Tears & Rotator Cuff Injuries

By Jason Griffin, MD

In my practice, two of the most common injuries I see are meniscus tears in the knee and rotator cuff injuries in the shoulder. 

They affect athletes, weekend warriors, and plenty of people who don’t consider themselves “active” at all. Because they’re so common, there’s also a lot of misinformation floating around. I spend a good amount of time helping patients separate misconception from reality so they can make the best decision for their recovery.

Here are some of the most common misconceptions I hear — and what I want patients to know instead.

Myth #1: “If it’s torn, it has to be fixed with surgery.”

Patients often come in worried that a meniscus tear or rotator cuff tear automatically means surgery. 

The truth is many of these injuries can be treated successfully without surgery.

With meniscus tears, especially small or degenerative tears, physical therapy, activity modification, and sometimes injections can relieve pain and restore function. Many people are surprised to learn they can return to walking, golfing, or even recreational sports without ever going to the operating room.

The same is true for rotator cuff injuries. In fact, a large percentage of patients improve with strengthening, improving shoulder mechanics, and reducing inflammation. My goal is always to match treatment to the patient — not just the MRI.

Myth #2: “I must have done something dramatic to tear it.”

Another common assumption is that these injuries only happen during a big event — a fall, a tackle, or a sudden twist. While that certainly happens, many meniscus and rotator cuff tears develop gradually over time.

I often see patients who say, “I just reached for something” or “I stood up and felt a pop.” That doesn’t mean the injury happened in that moment. More often, the tissue had been weakening for months or years, and that simple movement was just the final straw.

Myth #3: “If I can still move it, it can’t be torn.”

Patients often assume a tear would make them completely unable to move their shoulder or knee. 

In reality, many people with meniscus or rotator cuff tears still have good motion.

With meniscus tears, the most common symptoms are pain with twisting, catching, swelling, or stiffness — not total loss of movement. Some patients can even jog or exercise, but certain motions trigger discomfort.

Rotator cuff tears can be similar. Many patients can still lift their arm, but they feel weakness, pain at night, or difficulty reaching overhead. 

Myth #4: “I should just rest it until it heals.”

Rest has its place, especially early after an injury, but too much rest can actually slow recovery

For meniscus injuries, gentle movement helps keep the knee from becoming stiff and helps maintain strength. For rotator cuff problems, controlled motion is especially important. The shoulder is designed to move, and prolonged inactivity can make pain worse.

That’s why guided physical therapy is so valuable. It helps patients move safely while rebuilding strength and stability.

Myth #5: “Surgery recovery will take forever.”

Some patients delay care because they’re worried about a long recovery. While surgery isn’t always necessary, when it is the right choice, recovery is often more manageable than people expect.

Meniscus procedures are frequently done arthroscopically (using a small tube equipped with a camera and light). Incisions are small, and many patients are walking the same day. 

Rotator cuff repair does require more healing time, but we guide patients step-by-step. Most people return to normal daily activities well before they expect.

What I Want Patients to Remember

Meniscus tears and rotator cuff injuries are common. Surgery is not always required. Movement is usually helpful. And the earlier we evaluate the problem, the more options we have.

Most importantly, these injuries don’t have to keep you from doing the things you enjoy. Whether that’s sports, yard work, playing with your kids, or just sleeping comfortably again, there are options. My goal is always to help you get back to your normal — safely and confidently.
