Cycling is an excellent aerobic workout.Calisthenics, swimming, low-resistance rowing, stationary skiing machines, walking, hiking, and low-resistance weight lifting all are excellent ways to maintain fitness without overstressing the implant.
Suitable activities include bowling, croquet, golf, doubles tennis, table tennis, ballroom dancing and square dancing.
Other activities that are suitable but slightly more risky include downhill skiing, scuba diving, in-line skating, ice skating, softball, volleyball, speed walking, horseback riding, hunting and low-impact aerobics.
In general, patients who have undergone total knee replacement should avoid high-impact activities that cause high stress loads on the implant and therefore may increase the risk of early failure.
Activities to avoid include baseball, basketball, football, hockey, soccer, high-impact aerobics, gymnastics, jogging, power lifting , rock climbing, hang gliding, and parachuting.
