Here you will find answers to the top 20 questions about recovering from total knee surgery to help you understand what to expect and how to make the best recovery. 

Frequently Asked Questions

1) What is a Total Knee Replacement? 
A total knee replacement (TKR) is a surgical procedure to treat knee arthritis that has caused severe wear and tear to the knee joint, resulting in pain and stiffness.

Total knee surgery involves replacing the worn part of the knee with a new joint

Surgery involves removing the damaged and worn arthritic parts of the knee joint, the tibia, femur and sometimes the patella too.

These are replaced with a new prosthetic joint. Metal components are fixed to the thigh and shin bones and a plastic spacer sits in between. In some cases the patella is also removed completely and replaced with a plastic disc.

2) How Soon Can I Get Up After Surgery? 
Your physical therapist will help you to get up on the day of your operation, or the following day. 
You may need to use crutches or a frame initially when walking but that should only be for a few days. In most cases, you can put as much weight through your knee as feels comfortable after a TKR.

3) When Can I Go Home?
People are usually discharged home 3-5 days after a total knee replacement. Prior to discharge your physical therapist will ensure you can walk independently, get in and out of a car and go up and down steps/stairs.

4) How Do I Get Up & Down Stairs
The best way to get up and down stairs after a knee replacement is to take it one step at a time. The easiest way to do it is this:

The correct way to go up and down stairs with crutches. In these pictures, the affected leg is the right leg. Going Up - Good leg, bad leg, crutch. Coming down - crutch, bad leg, good leg.

When going up stairs, lead with your good leg stepping it up one step, then bring your operated leg up onto the same step and finally bring your crutches or sticks up to the same step. The simple mantra is "Good leg, bad leg, crutch".

When coming down stairs, place your stick/crutch down onto the first step, then step down with your operated leg, and finally bring your good leg down, all on to the same step. The mantra here is "Crutch, bad leg, good leg".

An easy way to remember it is "Good leg to heaven, bad leg to hell". On the way up, lead with your good leg, on the way down, lead with your operated leg. The crutch always stays with the operated leg.

If you have handrails, you can obviously use those. It may help to have a spare set of crutches so you can have one pair upstairs and one pair downstairs.

5) When Can I Return To Work? 
You can usually return to work 6-8 weeks after your total knee surgery, depending on what the job entails and how you are progressing through the total knee replacement recovery process. If you have a manual job it might take slightly longer.

6) Is Pain Common After Knee Replacement Surgery?
Yes, it is normal to experience pain after knee surgery for a few weeks as the skin, muscles and bone have been cut and take time to heal. This normally settles down within a few weeks.

Your doctor will prescribe pain-relieving medication which should be taken regularly so you can stay on top of the pain - don't try and battle through without it as you will only slow down the total knee replacement recovery process. You can find out more in the TKR problems section. 

Exercise is important during knee replacement recovery - cycling is a good way to improve knee movement and strength without aggravating your new knee

7) What Activities Can I Do? 
In the early stages of total knee replacement recovery you should stick to activities that don’t put too much force through the knee. Activities such as walking, swimming and gently cycling are all fine.

Start off slowly and gradually increase how much you can do being guided by your knee. Gentle exercise is an important part of total knee replacement recovery as using the leg and strengthening the muscles helps the recovery process.

8) Are There Any Activities I Should Avoid? 
For the first three months of total knee replacement recovery you should avoid anything that places lots of stress on the knee. This includes tennis, badminton, contact sports (such as football, rugby, baseball), squash or racquetball, jumping, squats, skiing, or jogging.

Also try and avoid any heavy lifting (more than 40 lb) or weight lifting as this could slow your total knee replacement recovery.

9) Can I Play Golf Again?
Yes you can play golf a few weeks after having a knee replacement, but do not wear spiked shoes as they cause the knee to twist too much. You might want to start by only doing half a course and gradually increasing the number of holes so you don't overdo things - often people don't notice any discomfort until the next day so pace yourself.

10) When Can I Have Sex? 
It is advisable to wait 4-6 weeks after your total knee surgery.

11) When Can I Do Housework? 
For the first three months following a TKR, stick to light chores such as washing up and dusting. Try to avoid standing for long periods e.g. ironing as it can cause your knee and ankles to swell.

After three months you can return to other housework such as hoovering. You may find kneeling uncomfortable, in which case get knee pads can really help.

12) How Long Do I Need To Do Exercises For? 
Exercises are a key part of the total knee replacement recovery process for a number of months if you want to get the best out of your new knee.

Exercises are vital to ensure you make the best total knee replacement recovery possible. Find out what exercises to do.

You should keep doing your knee replacement exercises daily until you have regained full range of movement of your knee, meaning you can fully straighten it and bend it at least 120°, and good strength in the muscles.

Even when you have achieved this, it is worth continuing with your exercises 2-3 times weekly to keep your new knee in its best condition.

Regularly doing your exercises is the best way to ensure you make a good total knee replacement recovery. Visit the knee replacement exercise section for more information.

13) How Do I Know If I’m Overdoing It? 
In the early stages of total knee replacement recovery, a bit of discomfort when doing something doesn’t mean you need to stop, however the discomfort should settle within thirty minutes. If pain continues for more than two hours after stopping the activity, that is a sign you overdid it. Next time reduce the intensity or time you do the activity for.

If an activity causes immediate severe pain, stop. Overdoing things is likely to slow down your total knee replacement recovery so listen to your body.

14) How Long Does Total Knee Replacement Recovery Take?
Many people find they actually have less pain after surgery as the pain from their arthritis is no longer there. After 6-12 weeks most of the post-op pain should have settled but their can be some residual pain and swelling for up to a year. You will continue to make progress up to two years after your operation so stick with it.
