Common Myths About Total Knee Replacement Surgery (and the Truth, According to a Hermitage PT)

If you’re facing the possibility of a total knee replacement surgery, you probably have questions. Maybe you’ve read a few things online or heard horror stories from a neighbor or friend. The reality is, it’s normal to feel uncertain. At Roscoe Physiotherapy, we talk with people every day who are navigating these decisions, and we hear the same fears again and again — many of which are rooted in misinformation.

That’s why we’re setting the record straight. Below, we’ll debunk some of the most common myths about total knee replacement and share the real story — so you can feel informed, empowered, and confident in whatever comes next.

Myth #1: TKR Surgery Is Only for “Old People”

Let’s clear this up: Arthritis, injury, and chronic knee pain don’t discriminate based on age. While it’s true that many people over 60 experience knee degeneration, we’re seeing more adults in their 40s and 50s opting for knee replacement surgery when pain starts interfering with work, hobbies, and everyday life.

Whether you want to chase after grandkids, hike local trails, or just get through the grocery store without wincing — age isn’t the deciding factor. Your quality of life is.

Myth #2: Recovery After Knee Replacement Is Long, Brutal, and Not Worth It

We won’t sugarcoat it: recovery after surgery takes work. But it’s not endless suffering. With a solid rehab plan and the right guidance, many people are walking independently within weeks.

Yes, there’s discomfort. Yes, there’s effort. But we see individuals every day who were once struggling to stand, now climbing stairs, returning to their fitness routines, and moving with more freedom — all through consistent rehab and trust in the process.

You get out what you put in — and with a skilled professional by your side, physical therapy offers a clear, step-by-step path so you're never left guessing.

That kind of clarity can be the difference between feeling stuck and making real progress. With direction and support, every step becomes more purposeful — and more possible.

Myth #3: You’ll Never Be Active Again After Total Knee Replacement

This is one of the most discouraging myths out there — and it simply isn’t true. Total knee replacement isn’t about limiting you. It’s about freeing you from the limits chronic knee pain has already placed on your life.

We’ve helped former runners ease back into mileage, retirees return to gardening, and active adults get back into recreational sports and strength training. Movement is medicine — and the goal of rehab for total knee surgery is to help you move and feel better than before.

Myth #4: Rest is best after total knee replacement surgery.

While it’s natural to want to rest after surgery, prolonged inactivity will actually slow your recovery. Early, controlled movement is essential to prevent complications like stiffness, muscle weakness, and scar tissue buildup around the joint.

Physical therapy introduces gentle, guided exercises soon after surgery (often even the day of surgery!) to promote circulation, maintain joint flexibility, and activate the muscles supporting your knee. This approach not only helps reduce pain and swelling but also sets the stage for a stronger, more functional knee.

Avoiding movement for too long can make regaining full range of motion and strength more difficult, ultimately prolonging recovery. That’s why balancing rest with carefully monitored activity is a critical part of healing after knee replacement.

Myth #5: If Surgery Goes Well, Physical Therapy Isn’t Necessary

We can’t stress this enough: physical therapy is a non-negotiable part of successful knee replacement recovery. The surgery replaces your damaged joint — but recovery is where you regain strength, restore mobility, and retrain your body to move well again.

Skipping or rushing through therapy can leave you with lingering stiffness, weakness, or even re-injury. The truth? A great surgeon sets the stage, but high-quality physical therapy after knee replacement is what gets you back to living the life you want.
