The key investigations for osteoarthritis are a full history and examination. The important features of the musculoskeletal history are assessment of pain and function from the affected joint. This detail can also be assessed with specific questionnaires. The examination is joint specific but for the most part involves an assessment of the swelling around the joint, tenderness around the joint line and restriction of range of movement.

Osteoarthritis Baseline Investigations
The most common investigation for osteoarthritis is a plain radiograph of a joint. This will be reported by a radiologist and will guide further investigations. MRI scans are rarely required to diagnose arthritis but can be useful in the very early stages of disease to assess minor cartilage damage and ligament injuries. USS can be used to assess soft tissue pain and swelling but is not generally used to assess osteoarthritis.

Once the diagnosis has been made a full management plan can be established. The initial treatment of osteoarthritis is non-operative and can be started in the community. It is important that patients are educated about osteoarthritis and the options for managing their symptoms. Early interventions include; analgesia, simple orthotics, physiotherapy, weight loss, complimentary medicine and steroid injections.
