WHAT … FOR? (Indications)
Bone implants are used to replace bony structures, e.g. in case of bone fractures and specific diseases. The joints between the bones, e.g. at the hip or knee, can also be replaced by so-called hip or knee endoprostheses in the case of very painful or significant joint changes.
Other reasons may include: limitations in walking and climbing stairs, a misalignment of the legs, an unstable joint or weak muscles, problems walking, kneeling or sitting down, limitations at work, at home and during leisure time, or dependence on support from others.
