Let’s talk about Hip & Knee Replacements…
If you’re beyond middle age, chances are you know someone who has had a joint replacement or is waiting for one. Maybe it’s you! Typically a total hip or knee replacement is offered to those in their 60s or 70s who have osteoarthritis (OA) causing significant pain and limited mobility that has not improved with a non-surgical approach.
The good news is that the majority of people who have surgery report significant improvements in their daily lives. But, there are some who have a harder time recovering and regaining their mobility after surgery. Let’s separate truth from myth so that you or your loved one are ready for the rehab journey!
Key Truth: Exercise matters before and after surgery
Research and clinical practice guidelines support early, progressive rehabilitation after joint replacement and show that prehabilitation (exercise and education before surgery) can improve strength/function and may improve some early post‑op outcomes.
-
Prehab (before surgery)- build your strength, balance & walking so you can go into surgery stronger, steadier, and more confident.
-
Post-surgery rehab- control swelling, improve joint mobility, build strength, functional mobility & balance so you can get back to doing what you love.
Consistently performing & progressing your exercises after surgery will pay dividends to your future mobility! Stay accountable & commit to the journey!
Let’s bust some myths around osteoarthritis(OA) and joint replacements!
Myth #1: “If it hurts during exercise, you’re damaging the joint.”
More accurate: Pain doesn’t always mean harm—OA symptoms can flare with stress, sleep, weather, and activity changes. A helpful guideline is the 24‑hour response: mild/moderate discomfort that settles back to baseline within 24 hours is often acceptable; pain/swelling that ramps up and lasts into the next day means reduce the dose. Most exercises can be modified as needed.
Myth #2: “Squats & stairs ruin your knees and cause OA.”
More accurate: When they’re scaled to your current level (depth, load, tempo, support), squats and sit‑to‑stands are often knee‑friendly strengthening that can improve pain and function. Strong leg & hip muscles are essential in managing OA.
Myth #3: “Running causes knee OA.”
More accurate: Recreational running is not automatically “bad for knees.” Risk is higher when there’s a history of significant injury, big spikes in training volume, poor recovery, or pain/swelling that’s repeatedly aggravated and ignored.
Myth #4: “You should avoid impact exercises forever if you have OA.”
More accurate: Many people with OA can tolerate some impact (walking, hills, small jog intervals) when it’s introduced gradually and progressed slowly. The right dose matters. Modifying exercise or using walking poles can make a huge difference in offloading the joints as well.
Myth #5: “Cartilage is like a brake pad—exercise just wears it out faster.”
More accurate: Joints are living tissues that respond to load. Strengthening helps the muscles share load and can improve movement efficiency and confidence.
Myth #6: “If your X‑ray is ‘bone‑on‑bone’, you shouldn’t exercise.”
More accurate: Imaging changes don’t always match symptoms. Many people with significant OA findings do very well with appropriately modified exercise.
Myth #7: “After a joint replacement, you can’t be active again.”
More accurate: Most people return to an active lifestyle with walking, cycling, swimming, and strength training. Your surgeon/physio will guide timing and any sport‑specific precautions.
Myth #8: “After a knee replacement you can’t kneel (ever).”
More accurate: While it will take time, kneeling is possible (and I would argue necessary!), but it can feel uncomfortable due to scar sensitivity/numbness, stiffness, and fear. With surgeon clearance, gradual practice (with cushioning and support) plus desensitization it can get better—and although not everyone finds kneeling comfortable, it’s important to know it is not harming your knee. Being able to get on and off the floor is a critical step in reducing your falls risk and enjoying your independence for years to come!
