it is really baffling how much lifting heavy weights for 30 minutes a week literally makes every single thing about your life better instantly. i cannot believe i spent so many years of my life not doing this. i wish someone had screamed at me to do this sooner

I’ve been an orthopedic surgeon for nearly 30 years, and a few patterns have become impossible to ignore. One is that many musculoskeletal problems in adults aren’t sudden injuries. They’re the moment when declining capacity and awful metabolic health finally reveals itself. Over the decades your strength fades, muscle mass declines, as your aerobic capacity tanks. Tendons and connective tissues lose substance, stiffness, and resilience. For years the body compensated... quietly. Then one day a knee hurts during a run to get the train, or shoulder aches reaching overhead, or a back tightens lifting something simple. At that point the story usually becomes more about structural damage. An MRI gets ordered. Welcome to high-tech, low-medicine. And the MRI almost always finds something. A meniscus tear. A rotator cuff tear. A disc bulge. Why? Because by midlife these findings are extremely common — even in people with no pain at all. If you have a tear in one shoulder, image the other shoulder... you probably have the same tear there. But I digress. Once the scan appears, the narrative changes. The image becomes the diagnosis. Now the patient believes something is broken, and the focus often shifts to fixing what the MRI shows. What often gets lost in this is the reason the symptoms appeared in the first place. Many so-called “atraumatic” orthopedic complaints are not purely mechanical failures. They are the moment when reduced strength, declining tissue capacity, and sometimes broader metabolic health issues finally reach a tipping point. Our tissues change over the decades... get over it. In other words, the MRI didn’t create the problem. Well... it sort of did in this scenario. But all the MRI showed was something that was already there.... because of your age, lifestyle, health and so on. The real driver of symptoms is often loss of physiologic reserve. Less muscle. Less tendon or aerobic resilience. Less tolerance for load, etc. Once the MRI enters the picture, the risk becomes overtreatment. This is probably the number one reason people have surgery. When in many cases the most powerful intervention was never the scan or the procedure. It was rebuilding capacity. Strong muscles stabilize joints. Aerobic fitness improves metabolic health and tissue perfusion. Gradual loading restores tolerance. But people often don't take PT seriously prior to surgery. They often take PT very seriously afterwards. Therefore, PT is probably the reason you feel better, despite the surgery. The irony is that the treatment many people ultimately need is the same thing that might have prevented the problem in the first place. Staying strong. Staying active. Maintaining the reserve that protects our joints/tendons/muscles/abilities as we age.

The hardest conversation I have in my office isn't about surgery. It's about time. A 58-year-old sat across from me with knee pain. She’s otherwise healthy, but menopause has been rough on her. Her MRI shows some cartilage changes — age-appropriate, and a typical meniscus tear... basically, nothing that requires surgery. But she hasn't done any physical work in 15 years. She stopped playing tennis at 43. Stopped walking regularly at 50. Now the knee hurts when she climbs stairs. The knee isn't the problem. The knee is just the messenger. What has really happened is fifteen years of progressive capacity loss. Muscle mass has declined while tendon capacity has dropped. Her metabolic health shifted, and menopause has contributed to these changes. The knee was affected secondarily. The knee doesn't require my attention... that needs to be directed elsewhere. I can't give her those fifteen years back, but I can help her start from where she is. And starting from where she is still works. An 85-year-old can still synthesize new muscle protein after a single resistance-training session. The window of opportunity does narrow with age, but it never closes. Recovery takes longer. The risk of injury is likely higher. Progress is slower. But the biology of adaptation doesn't abandon you at 58, or 68, or 78. What changes is the cost of waiting. Every year of inactivity makes the starting point harder and the ceiling lower. The leverage you have at 40 is real and significant — and it's greater than the leverage you'll have at 60. That's not a reason for despair... It's a reason to start, wherever you find yourself now. 3 months later, after a solid strength/power program, she's walking daily with her weighted vest and is back on the tennis court.
