 [ Symptoms ] what should i expect from having knee manipulation after total knee replacement tkr [ Disease ] i do not know if i have sleep apnea i dont think i have ever been tested for it i am an extremely deep sleeper but every so often i do wake up once or twice in the middle of the night before my alarm wakes me up i just figured that is because where i live is very noisy due to people speeding by and other things i am basically in the city normally i do not often have disrupted sleep and i usually do not get woken up by anything during the night
