How to Prepare for Knee Replacement Surgery

Preparing for knee replacement surgery means getting your body, your home, and your support plan ready in the weeks before your surgery date. The steps that help most are prehabilitation to strengthen the muscles around the knee, setting up a safe and reachable recovery space at home, arranging rides and help for the first week or two, and working through your surgeon's pre-op instructions on medications and appointments. Starting a few weeks out gives each of these time to fall into place.

If you have a knee replacement on the calendar, the weeks before surgery can feel like waiting for something you cannot quite picture yet. This walks through what to do with that time, so you arrive prepared and come home to a setup that supports your recovery.

Much of how the first weeks feel is decided before you reach the operating room. How ready the muscles around your knee are, how safe and reachable your home is, and how much help you have arranged all shape the recovery you come home to. Patients who use the prep window well tend to move through those early weeks with fewer surprises.

Start Your Prep About Three to Four Weeks Out

A simple order of operations for turning the wait before surgery into useful work.

Most of the prep spreads across the three to four weeks before surgery, with the medical and physical work starting earliest and the logistics landing in the final days. A rough order looks like this.

1. Three to four weeks out. Begin the prehab exercises your surgeon or physical therapist recommends for the quadriceps, hamstrings, and hip muscles. Schedule your pre-op appointments and complete any medical clearances you are asked to get.
2. About two weeks out. Set up your home. Clear the paths you will walk most, move everyday items to counter height, and arrange the chair, bed, and bathroom setup you will rely on.
3. At least one week out. Line up your recovery equipment. If your plan includes a cold therapy rental, reserve it at least 7 days before surgery so it arrives before you come home.
4. The final few days. Confirm your ride, your helper for the first week, a few prepared meals, and your hospital bag. Follow your surgeon's instructions on which medications to pause and when to stop eating before surgery.

The Four Areas to Get Ready

Your body, your home, your help, and your paperwork, taken one at a time.

Strengthen the Knee Before Surgery

The work you put in before surgery, often called prehab, gives you a stronger base to recover from. After a knee replacement, swelling around the joint suppresses the muscles that move and stabilize it, which slows the return of strength in the first weeks. The stronger the quadriceps, hamstrings, and hip muscles are going in, the more you have to draw on afterward. Ask your surgeon or physical therapist which exercises fit your knee, and start them as soon as they clear you.

Set Up Your Home for an Easy Recovery

You will move slowly and lean on a walker or crutches at first, so the goal is a home where everything you need is close and nothing is in the way. Clear the walking paths between your bed, bathroom, and a main sitting spot, and move loose rugs and cords out of them. Move daily items up to counter or waist height so you are not reaching low or climbing. If your bedroom is upstairs, consider setting up a temporary sleeping space on the main floor for the first week or two. Set up a recovery station near an outlet with water, medications, a phone charger, and anything else you use often within arm's reach. A firm chair with armrests and a raised toilet seat both make standing up easier in the early days.

Arrange Your Help and Your Rides

You will not be able to drive for a few weeks, and you will want someone around for the first several days at least. Line up a person to stay with you or check in during the first week, and sort out rides to your follow-up appointments and physical therapy. Cooking is hard on one leg, so prepare and freeze a few meals ahead of time, or arrange for someone to handle food during the first stretch. If you have pets or kids who need daily care, plan for who covers that while you are focused on recovering.

Work Through the Medical Checklist

Your surgical team will give you a pre-op checklist, and it is worth working through it early. That usually includes a pre-surgical physical, blood work, and a review of every medication and supplement you take, since some need to be paused before surgery. You may also be asked to complete a dental or other clearance. Read the day-of instructions closely, especially the ones about when to stop eating and drinking, and write down any questions as they come up so you have them ready for your surgeon.

Questions to Ask and Loose Ends to Tie Up

The last conversations and logistics before your surgery date.

Before the final week arrives, bring your list to your surgeon. Good questions to settle include which medications to pause and when, what your weight-bearing and range-of-motion plan will be, what kind of anesthesia to expect, and whether cold therapy before surgery is appropriate for you. Getting these answered first means the logistics that follow are just execution.

One thing worth settling early is how you will manage swelling in the first weeks, since keeping it down is one of the few levers you directly control. Cold and compression therapy is a common tool for it, and the options run from ice packs to gravity-fed ice machines to iceless units. If you want to see how those compare, our guide to the best ice machines for knee surgery recovery walks through them. Systems like the NICE1, an iceless cold and compression unit used across more than 250,000 procedures, hold a set temperature and run overnight without ice refills, which is why many patients rent one for the early weeks. Whichever you choose, reserve any rental at least 7 days before surgery so it arrives before you come home.

Good preparation clears the path so your energy goes where it counts once you are home, instead of into scrambling for things you could have set up in advance. Do the prep you can, lean on the people around you, and follow your surgeon's plan.
