Why does my knee pop when I walk?
Patient: My knee usually pops when i walk.  Doesn't hurt just makes a popping noise that others can hear.  Last night when I was sleeping, my knee started to hurt and almost felt like it needed to pop like you would with your knuckles.  Every once in awhile it does happen but not as often as my knee popping.  Any ideas? Doctor: Hi...The popping noise in your knee is due to friction developed in the knee due to muscle imbalance.The bone slides over the other and move, at the end of movement give rise to pop while releasing the frictional pressure..I suggest you to kindly do lot of stretching of the muscles around the knee especially Quadriceps  Hamstrings and calf...Do lot of icing around the knee...Do glute strengthening exercises like... Bridging clamshell..step ups...squats...Do calf raises...Hope this is helpful for you...Kindly revert back in case you need any further clarification...
