• How do I take care of my surgical wound?
• What medications do I take at home?
• Can I take a shower?
• How can I get my home ready?
• When can I go back to see my dentist?

Pain Management1,2,5

Pain management is an important part of your recovery. The following approaches can help:
• Doctor-prescribed oral medication
• Physical therapy
• Assistive knee braces


Bruising may last for up to 2 weeks. Bruising is often normal, but consult your surgeon if you have concerns. To help reduce bruising, try elevating your leg with a pillow.


Swelling may be present for as long as 6 months post-surgery. The following approaches can help:
• Post-op exercises
• Leg elevation
• Physical therapy

Next Steps1,6

The success of your surgery depends heavily on what you do once you go home.
• Over time you will return to a regular level of activity.
• It is important to reduce the impact on your knee joint. Some activities involve higher impact than others, for example: downhill skiing, soccer, basketball, and repetitive lifting or squatting.
• Low impact activities such as hiking, gardening, swimming, tennis and golf are encouraged.
• The use of an assistive knee brace may help to reduce joint impact and pain.

Home Set-Up Tips

Becoming aware of possible hazards in your home can make your recovery easier and safer.
• Rearrange furniture to make moving around the house easier.
• Remove throw rugs that could cause you to slip or trip.
• You may want to temporarily rearrange rooms to avoid using the stairs (e.g., make the living room the bedroom).
• Bathroom: Install a shower chair, grip bar and a raised toilet seat.
• Sit in a proper chair that is firm, doesn’t sit too low and has a footstool for leg elevation.

Keeping Your Knee Healthy

Follow your doctors advice to ensure a successful recovery
• Walk regularly and continue to do your recommended exercises every day.
• Avoid activities that could cause a fall.
• Try to minimize stress on your knee throughout the day.
• Use an aid or brace to keep weight off your healing knee.
• Advise your dentist of your knee surgery – antibiotics may be necessary to prevent infection.
• Contact your surgeon or family doctor at any time if you have concerns.
