TKR Questions after TKR

I'm experiencing that my "new" knee locks when I am walking. Is this normal after a TKR? I'm also experiencing numbness and my leg "going to sleep" which makes it uncomfortable while sleeping. Is this too normal? I had my surgery on 1/15/2020 so I'm still a newbie with recovery.

@Monina10 ,
Welcome to BoneSmart, glad you joined us! :welome:
Your knee is probably locking due to hamstrings not working when they should. Common after a major surgery such as a TKR.
If you are being seen by a PT they should be able to help you with hamstring control.
A numb area on the outside of your knee is normal. Sounds like your whole leg is falling asleep, not sure why this is happening, may be from having to sleep on your back. What position is your leg in when sleeping?

Here is your copy of the Knee Recovery Guidelines, the articles are short and will not take long to read.

Knee Recovery: The Guidelines
1. Don’t worry: Your body will heal all by itself. Relax, let it, don't try and hurry it, don’t worry about any symptoms now, they are almost certainly temporary
2. Control discomfort:
take your pain meds by prescription schedule (not when pain starts!)​

3. Do what you want to do BUT
a. If it hurts, don't do it and don't allow anyone - especially a physical therapist - to do it to you​
b. If your leg swells more or gets stiffer in the 24 hours after doing it, don't do it again.​

4. PT or exercise can be useful BUT take note of these

5. At week 4 and after you should follow this

6. Access these pages on the website

The Recovery articles:
The importance of managing pain after a TKR and the pain chart
Swollen and stiff knee: what causes it?
Energy drain for TKRs
Elevation is the key
Ice to control pain and swelling
Heel slides and how to do them properly
Chart representation of TKR recovery
Healing: how long does it take?

Post op blues is a reality - be prepared for it
Sleep deprivation is pretty much inevitable - but what causes it?

There are also some cautionary articles here
Myth busting: no pain, no gain
Myth busting: the "window of opportunity" in TKR
Myth busting: on getting addicted to pain meds

We try to keep the forum a positive and safe place for our members to talk about their questions or concerns and to report successes with their joint replacement surgery.

While members may create as many threads as they like in a majority of BoneSmart's forums, we ask that each member have only one recovery thread. This policy makes it easier to go back and review history before providing advice.
