Probably not.: Knee buckling is a typically a feature of internal derangement such as meniscal tear. Mechanical symptoms such as buckling or locking are best evaluated by an orthopedic surgeon. Complex regional pain syndrome is a neurologic disorder with pain, swelling and skin changes as the predominant features.

CRPS: I think you might experience degenerative joint disease in the knee, not complex regional pain syndrome. Complex regional pain syndrome (crps) is a form of chronic pain that usually affects extremity. Crps typically develops after an injury, surgery, but the pain is out of proportion to the severity of the initial injury.
