Osteoarthritis
Conditions
Brief summary
In this study, the investigators use the clinical documentation and imaging data of MRI to do research. Clinical subjects were divided into two groups: osteoarthritis patients and healthy controls without osteoarthritis. Differences of MRI data were studied between two groups.
Detailed description
In this study, the investigators applied high precision MRI technique (with as less as a slice thickness of 0.35 mm and without inter-slice gap), and calculated not only the IPFP maximal sagittal area and IPFP volume, but also the quantitated signal, and compared the differences between healthy controls and osteoarthritis patients. This is an observational cross-sectional study without specific interventions to the subjects. MRI is a regular examination in our hospital. And all subjects are included for the reasons of osteoarthritis (need MRI) and healthy controls (pain but not osteoarthritis, also need MRI). The investigator does not assign specific interventions to the subjects of the study.
Interventions
3.0 T Magnetic resonance imaging of knee joints. It does not harm the subjects.

| Osteoarthritis Patients 3.0 Tesla Magnetic resonance imaging was analyzed. It's the documentation from the outpatients and inpatients with osteoarthritis. It's not the intervention the study applied, but the subjects' disease demands.
