Still swelling mainly lateral side knee after Tkr

Everything you are experiencing is normal. Even though the outside of your TKR looks healed, internally it takes about a year to completely heal.

Swelling is a sign of doing too much too soon. Ice your knee often and elevate it as much as you can. I had my TKR right side on April 14th, 2016 and I'm amazed at the amount of swelling I experience often. It looks like someone has blown it up with a bicycle pump!

I do physical therapy 2 times per week with a therapist for an hour, plus 3 times a DAY I do my own exercises.

Work that knee, ice that knee and rest that knee!

Just remember, we all heal at our own rates.

Here ya go...

Hope it helps... 

I struggled with swelling with my left TKR but hardly any with my right TKR three months later. It is strange how one knee can be so different from the other!

Ice helped a bit, but elevating my legs way over my head, resting them on the headboard of the bed did the most to help me. ( My son is an elite athlete and puts his legs up the wall following his long-distance runs. He helped me adapt this by looping a belt over my foot to raise my leg up while on my bed. Works wonders, and feels great!)

Compression stockings that are thigh-high help, too. I put them on both legs.

Anti-inflammatories like Ibuprofen reduce swelling without any nasty side effects like narcotics often produce.

Drinking LOTS of water and watching salt intake can help with SWELLING , too.

I practiced walking barefoot inside my house. Walking barefoot allowed me to concentrate on placing my foot properly -- heel first then gently rolling the foot to the toe. I worked hard to go slowly and methodically, trying to be as fluid as I could.

For YEARS I apparently walked strangely due to compensating for the terrible pain from my bones rubbing together. I walked with knees bent which shortened my hamstring muscles. These muscles and the ligaments behind my knee needed to be gently stretched back to normal. I worked on this by sitting in a chair and putting my legs up on an ottoman. At first I could tolerate it for just seconds. I slowly worked up to several minutes then longer and longer. I continue to stretch like this when I sit reading or watching TV. I also press the back of my knees into the mattress in bed and hold for a count of ten, release and the repeat several times. This helps me throughout the night and especially prior to getting out of bed.

I hope these ideas help you!😊

Sorry I'm slow to respond, I share your frustration with having both knees an issue.  As much as you probably don't want to hear this I would suggest using a cane to help with your gait and back issues.  Your PT can teach you how to use it properly and provide suggestions for improvement when walking.  Sometimes we need something like a cane to help remind us we're still healing.
