@KMLknee, On recommedation of my PT instructor, I purchased a mini peddler, for the first few weeks I diligently used it, then slowly it started to gather dust and it is now almost totally ignored,
unless you are extremely disciplined, which I'm not, in my case it was a waste of money. Do make sure you buy a sturdy one, they need to have good suction to the ground, mine albeit being expensive has to be put in front of a block or wall to stop it moving on the floor tiles.
Muscle spasms at night are most common, usually caused by over activities during the day, for leg cramps I try to eat a banana daily or you can take a magnesium supplement this will help reduce the frequency.
Two nights ago I experienced the most awful hamstring cramp
I often get calf cramps but this one was out of the blue and never before had I felt do much pain
Thankfully it only lasted seconds, more bananas for me. Noise, clicking and clucking of the knee are normal unless there is pain, if it's painful consult with your surgeon, otherwise with time, (lots of time) it will usually go away. I'm now, nearly 10 months post surgery and despite it being less noticeable, now only certain activities it gently reminds me, my clicking started immediately after surgery to the extent I thought my surgeon has misaligned my knee. Thankfully fellow Bonesmarties put my over active mind to rest.
As I said, unless it hurts there is no cause to worry - great to hear you have got your new surgery booked
