Obligatory medical device diagnostics.
- Radiographs of the affected joints
Optional medical device diagnostics – depending on the results of the history, physical examination, laboratory diagnostics and obligatory medical device diagnostics – for differential diagnostic clarification.
- Computed tomography (CT; sectional imaging procedure (X-ray images from different directions with computer-based evaluation), particularly well suited for the depiction of bony injuries) of the affected joints – findings correspond to the X-ray images, but earlier depiction possible; better depiction of complex structures.
- Magnetic resonance imaging (MRI; computer-assisted cross-sectional imaging method (using magnetic fields, that is, without X-rays); particularly well suited for imaging soft tissue injuries) of the affected joints – indication mainly in cartilage and meniscus damage.
- Arthroscopy (arthroscopy) – if necessary, small tissue samples of the damaged cartilage or synovial fluid (synovial fluid) are taken and examined in the laboratory Find loose bone parts or cartilage pieces can be removed during the same procedure by a lavage (irrigation).
- Arthrosonography (ultrasound examination of joints) – this also reveals joint effusions, soft tissue processes and fluid accumulation in the joint. This examination is also performed before a puncture or injection. The joint effusions or fluid accumulations can then be treated with medication – if necessary also by puncture. Does not count among the methods of choice for osteoarthritis!
