Eligibility

Sex/Gender

All

Age

18 Years to No maximum

Inclusion criteria

Inclusion criteria: Adult patients who had a unilateral implantation 1-2 years ago have received a total hip replacement at the Heidelberg University Hospital and have a healthy, pain-free hip joint on the opposite side are included in the study. Either the patients are included in their standard final examination Approx. 1 year postoperatively examined or contact is made via our Arthroplasty register and patient invitation for the study.

Exclusion criteria

Exclusion criteria: Age under 18 years - Inability to consent - Known contrast media intolerance to SonoVue® or others ultrasound contrast media. - Allergic reaction when given SonoVue® - Lower extremity deformities - Complaints or previous surgeries in the area of ??the contralateral hip joint - Patients with known right-to-left shunt, severe pulmonary hypertension (pulmonary artery pressure > 90 mmHg), uncontrolled systemic hypertension or acute respiratory distress syndrome - Pregnancy and breast feeding period. - Lack of informed consent or - refusal to participate.

Design outcomes

Primary

Measure	Time frame
The muscular microperfusion is individually referenced based on the healthy contralateral side of the M. gluteus medius 1-2 years after implantation of a hip TEP after minimally invasive Access more even and more pronounced than after conventional lateral access.	—

Secondary

Measure	Time frame
There is a correlation between the muscle perfusion and the functional result thus the ability to regenerate the muscles damaged by the surgical access.	—
