Both Knees at Once, or One at a Time? How to Think It Through

Should you replace both knees at the same time or stage them? A physical therapist on the tradeoffs — and why there’s no universal right answer.

One of the biggest decisions people face is whether to replace both knees at the same time. The answer isn’t a simple yes or no.

Some people do incredibly well having both knees done at once. Others are very glad they only had to go through one surgery and one recovery. And plenty are happy they staged their surgeries, one knee at a time. There’s no universal right answer.

The tradeoffs

Both at once can mean one surgery, one hospitalization, one major recovery, and one time away from work — but also two surgical knees, more dependence on others early, and a potentially more challenging recovery.

One at a time may let you lean on the stronger leg during recovery — but it means going through the process twice: two surgeries, two recoveries, two rounds of rehab.

The best choice usually depends on the individual: your age, overall health, strength, support system, goals, and your surgeon’s recommendation — far more than what worked for someone else online. Whichever path you choose, preparation, patience, and consistency tend to matter more than the route itself.
