Running can put a tremendous amount of stress across your new implant. I would be very careful before starting a heavy-exercise program on your new knee replacement. Despite this, you can still be an athlete and do certain types of activities. The American Academy of Orthopaedic Surgeons (AAOS) recommends the following activities with a total knee:

– Bicycling

– Calesthetics

– Swimming

– Low-resistance rowing

– Gentle Skiing

– Walking & Hiking

– Low-resistance weightlifting

Similarly, the AAOS advises against high-impact activities:

– Baseball

– Basketball

– Football

– Hockey

– Soccer

– High-impact aerobics

– Gymnastics

– Running and Jogging

– Powerlifting
