Can You Run After Knee Replacement? A Better Look at High-Impact Activities and Safer Alternatives
Dr. Nathan Cafferky, a board-certified orthopedic surgeon and joint replacement specialist at The Steadman Clinic in Vail and Frisco, Colorado, knows that many patients undergoing total knee replacement hope to return to an active lifestyle. A common question he hears: Can I run after knee replacement?
The short answer: it’s not recommended. While today’s knee implants are more durable than ever, running and jogging place high, repetitive forces on the joint—forces that may lead to earlier wear or implant failure.
Why Running After Knee Replacement Isn’t Ideal
Knee replacement surgery is designed to reduce pain, restore mobility, and allow patients to resume many of the activities they love. But while new implant technology has improved, the mechanics of running can still take a toll.
“Running and even light jogging create repeated impact loads on the knee joint,” says Dr. Cafferky. “Over time, this can increase the risk of implant loosening or wear. For that reason, I don’t recommend running or jogging as a form of exercise after knee replacement.”
That doesn’t mean you can’t stay active—or push yourself physically. It just means choosing exercises that protect your new joint while keeping your cardiovascular fitness high.
Safer, Joint-Friendly Alternatives to Running
For patients used to the endorphin rush of a run, switching activities may feel like a loss—but it doesn’t have to be. Here are Dr. Cafferky’s top alternatives that offer excellent aerobic benefits with far less impact:
Cycling – Great for leg strength and cardiovascular health with zero joint impact.
Swimming – A full-body workout that’s easy on the joints but high on results.
Elliptical Machines – Mimics the motion of running with controlled, low-impact movement.
Nordic Walking or Hiking – A more dynamic option that improves strength and endurance, especially when done on varied terrain.
Doubles Tennis and Golf – Both are safe recreational sports that keep you active without exposing the joint to repetitive pounding.
“These activities are sustainable and safe for most patients,” says Dr. Cafferky. “They let you stay strong, fit, and mentally sharp—without compromising your knee replacement.”
Reframing Your Fitness Goals
It’s natural to feel discouraged if running was part of your routine pre-surgery. But long-term success after total knee replacement often means adapting. With the right mindset and exercise plan, you can enjoy an active, pain-free life for years to come.
“Focus on movement that supports your new joint, not challenges it unnecessarily,” Dr. Cafferky advises. “It’s about longevity and quality of movement—not just intensity.”
