Hello and Welcome to BoneSmart and recovery. Congrats on your new hip!
As far as Leg Length Differential goes, you're not alone, many feel this sensation post op. In most cases it eases with time. We advise giving it 3-4 months as it can take that amount of time for things to balance. If at that point, you are still concerned we suggest you visit a reputable podiatrist or PT for a measurement.
Here's an article from our Library Leg length differential - LLD
If you feel you’re still experiencing Log Leg, see if the description below matches what you’re feeling.
Log Leg - your brain is telling your leg to move but the muscles and soft tissue have been so traumatized that there's no reaction.
Here is a more detailed explanation I found through reading up on this topic -
The first stage of healing is the inflammatory phase. During this time it is very common to notice swelling. After lower extremity surgery, or trauma involving bleeding and inflammation, there will be fluid in the leg causing the sensation of heaviness. Gravity pulls the fluid downward and since the patient is less mobile the fluid is not pumping back through the heart as quickly. The swelling gradually eases, but can persist for up to 3-6 months in some cases. Regular movement will assist in the reduction of swelling, as will elevation and ice. Your surgeon may prescribe compression stockings for a short period of time.
Following joint replacement, you may benefit from the use of a Leg Lifter. The Leg Lifter is a mobility aid that can assist in getting in and out of cars, wheelchairs, beds, recliners and much more. The Leg Lifter is an inexpensive option that helps provide safe movement in the early days, to weeks, of recovery.
I‘m not really sure what you mean by kicking your leg out. Do you mean raising it to the side, or just extending it out, straight, in front of you? You’re only three weeks into a healing process that can last a full year for some. I’m sure it will come with time. Wondering what it is that you do for work that you’re concerned about holding you back?
If you’re experiencing swelling, try icing if you’re not already. You’ll find a article on Ice in the Recovery a Guidelines below.
I wish you the best as you continue healing. Stop back if you have questions and we’ll do our best to help.
