For Germany, a scientific review is still pending. Modified perioperative measures but also a shortening of an inpatient stay must not reduce the currently existing high quality of care in arthroplasty. A possible reduction in the length of inpatient stay implies a compression, but not necessarily a reduction in the perioperative care required for a patient. For this reason, the surrounding conditions must also be created at a political level in the future to enable the achievement of the desired high quality.
