Knee problem after playing basketball

[jwilson]

While playing basketball the other day, my left knee began to weaken after cutting back and forth.  Now it is weak all the time and sometimes almost gives out.  Most steps are fine, but every once in a while, there is a sharp pain.  I also feel like there is something moving around in there that I didn't feel before.  Any ideas?

Go check your knee out and stop all activities meanwhile to not do more damage.
You should see a OS(orthopedic surgeon) specialized on knees.
