With advanced OA,crepitus(a grinding sensation) may become noticeable.
The lateral tibiofemoral joint (outer side of the knee) is less commonly so.
Loose bodies in the joint space may also contribute to pain and stiffness.

Once diagnosed, stick with a regimen consisting of proven and effective treatment options.
