The left knee is still improving here and there, though the contracture on the quadriceps and hamstring will take time to improve. Booktoots' post, Walking On Gravel & A TKR, reminded me of while I was at a Florida beach recently.
While solid ground is easier to walk on, it's the uneven areas that give me some trouble. I know that will improve in time. It was a bit of slow going from a table near a parking space through the sand to the water's edge. I was able to walk into the water, but a drop-off gave me a little trouble and an outgoing wave swept my feet from underneath me. A nearby mother with young child thought it was pretty funny. From there it was easy enough to stay in the water and move around despite the waves.
But getting out took a little creativity. I couldn't just get out normally like others could. My cane was still at the table. It took me a couple tries to actually get past the drop-off. I used the incoming waves to help push me up past the drop-off. A wave came in, take a couple steps, wait for the next wave to come in, a few steps, til I was past the drop-off. Walking back from there to the table was a bit slow and difficult going, but I made it.
Pool ladders still give me trouble, but after my right knee is worked on, that should be resolved in time.
