Brief Summary
The purpose of this study is to investigate the effectiveness of a hip arthroplasty for chronic pain, caused by a unilateral primary Coxartrhrose, regarding the cognitive performance. It is based on the hypothesis that the combination of chronic pain along with relative immobilization causes impairment of cognitive performance. The total hip replacement reduces pain, increases the mobility level and finally improves the cognitive performance.

Study Arms (2)
intervention group
Patients with primary, unilateral hip osteoarthritis in inpatient orthopedic acute treatment, who have a medical indication of a necessary artificial hip replacement implantation.
control group
Volunteers without chronic pain. As a control condition for comparing the variation in cognitive performance and everyday activity the investigators use a group of pain-free and mobility-unrestricted subjects, who do not receive or have an artificial hip.
Interventions
To objectively quantify the everyday activity, there are a variety of instruments, without a currently gold standard. Therefore, in addition the investigators use objectified measurement parameters with the aid of a pedometer (GARMIN vivofit) on every three measuring time points (before surgery, 3 months after surgery, 6 months after surgery).
Standardized neuropsychological assessment methods are used to assess the cognitive performance. To assess the degree of mobility, health status and the physical activity standardized questionnaires are used.
Eligibility Criteria
Patients are enrolled in this study, who are diagnosed in the orthopedic clinic of Klinikum Bad Bramstedt or in the orthopedic clinic at University Medical Center Hamburg-Eppendorf. Study participants with the diagnosis of primary, unilateral coxarthrosis (ICD-10-GM: M16.1) are added consecutively in the intervention group, if they need a hip replacement because of their condition and decide to undergo this hip replacement in the orthopedic clinic of Klinikum Bad Bramstedt.
You may qualify if:
- primary, unilateral coxarthrosis
- planning for hip replacement surgery in Bad Bramstedt
You may not qualify if:
- dementia / cognitive impairment (Mini Mental Status Test \<25)
- chronic pain otherwise genesis
- reduced physical activity otherwise genesis
- lack of German language skills
- uncorrected serious impairment of vision or hearing
- serious additional psychiatric diagnoses (e.g. substance abuse / addiction)
