Hello and Happy Saturday!
At only ten days post op, you don’t need to be doing much aside from icing / elevating, resting and taking a 5-10 minute walk every hour or two which can usually be accomplished by a trip to the bathroom, or kitchen to get a drink or something to eat.
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 researching -
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.
If you don’t have a Leg Lifter, the belt from a bathrobe will work just as well. Hope this helps.
