Knee Replacement Recovery Time

Knee replacement recovery begins before your surgery. You will have a rehab program to work on which you can actually start before your operation to get your muscles in the best shape possible which will really help. The people who make the best total knee replacement recovery are the ones who start the rehab process before their operation.

Knee Replacement Recovery Time Guide

Here we will look at total knee replacement recovery time, including what happens at what stage post-op and how long it typically takes to get back to your usual activity.

If are having or have had only one side of your knee replaced, visit the partial knee replacement recovery time section instead to found out how it will be for you. 

Knee replacement recovery time will vary from person to person, and may be affected by:

• Severity of arthritis 
• Activity levels prior to surgery
• Weight
• Age
• Compliance with exercises pre and post-op

Let's have a look at a typical knee replacement recovery time process.

1. The First Week

3. The First Month

Once you are discharged from hospital, you will continue your knee replacement recovery at home. Your knee may well be sore and swollen after your knee replacement initially but the pain is often much less than before the surgery as you will no longer be getting any knee arthritis pain.

As the knee heals, your post-op knee replacement recovery pain will settle down, usually within a few weeks and you'll be advised on how to wean off your medication.

One of the best ways to reduce pain and improve range of motion after a knee replacement is to get any knee swelling down as quickly as possible using things like Ice and Tubigrip (a special compression bandage).

After about a month you should notice quite a dramatic improvement in your knee.

Knee replacement recovery time will be impacted by how well you comply with the recommended rehab programme. It is really important to be doing exercises to build up the strength and flexibility around your knee to gain the full benefit of the surgery (see the exercises for knee replacement section).

During this period of knee replacement recovery time be aware of:

• Wound Care: You must keep the wound clean and dry until the stitches are removed, usually after 7-10 days.
  
  
• Driving: You can drive after 4-6 weeks, as long as you can perform an emergency stop.
  
  
• Walking: You will be able to stop using any walking aids such as crutches or sticks as soon as you feel able – usually in a few days, and certainly by six weeks.

4. The First 3 Months

Returning to Activities / Sports

With knee replacement recovery time is one of the biggest healers. Over time the swelling will reduce, your muscles will get stronger and your knee should free up becoming more flexible than beforehand.

It is important to take things easy for the first few weeks but after that, you can start thinking about returning to your favorite activities. Here are some helpful tips on knee replacement recovery time:

• You can resume most activities after 6-12 weeks, for example swimming
  
  
• Some activities should be carried out with care e.g. golf – don’t wear shoes with spikes
  
  
• Some activities are not advised following a total knee replacement as they put too much stress on the new knee joint. These include: jogging, contact sports e.g. basketball and football, squash, badminton, jumping activities and skiing. If you are unsure, discuss things with your doctor.

Pain and swelling can take up to 3 months to settle and knee replacement recovery time continues up to 2 years after your operation.

Knee Replacement Recovery Tips

2. How Do I Sleep After A Knee Replacement? Typically people find it most comfy to sleep on a firm mattress, either lying on their back or on their side with a pillow between their legs.

• Day 6-10: Continue with daily exercises (2-3 times per day) and take regular walks around the house. Aim for full knee extension and at least 90 degrees of knee flexion. Can wash as long as you keep the dressings dry. Stitches removed.
  
  
• Weeks 2-6: Progress to more challenging exercises (still 2-3 times a day), start walking around outside (may still need walking aids initially). Avoid kneeling, squatting and pivoting. Start driving again - must be able to do an emergency stop.
