Osteonecrosis is a disease characterized by a derangement of osseous circulation that leads to necrosis of osseous tissue. Osteonecrosis of the knee has been divided into 2 separate entities: spontaneous osteonecrosis of the knee (SPONK) and secondary osteonecrosis.
spontaneous
The antonym of spontaneous is planned or intentional.
If G < 0, the reaction is spontaneous.
Spontaneous is an adjective. The related noun may be "spontaneousness" or "spontaneity."

Fosamax which can cause Osteonecrosis (the bone dies)
Osteonecrosis is a condition where the blood supply to a bone is disrupted, leading to bone tissue death. This can result in pain, joint collapse, and limited joint movement. Common sites for osteonecrosis include the hip, knee, and shoulder.
Osteonecrosis of the jaw, generally associated with tooth extraction and/or local infection, often with delayed healing, has been reported in patients taking bisphosphonates(fosamax).
Osteonecrosis means bony necrosis.
spontaneous
In the context of "spontaneous vs non-spontaneous," a reaction is considered spontaneous if it occurs on its own without needing external influence. On the other hand, a non-spontaneous reaction requires external energy input to occur.
