The correct management of osteoarthritis requires an accurate diagnosis, evaluation of its spread and functional repercussions, and the application of comprehensive and effective individually-tailored treatment aimed at relieving pain and improving physical function with a consequent improvement in quality of life; treatment should also aim to prevent or delay disease progression and its effects. In the National Health Service, primary care is the basic level and the first point of access to healthcare; this level guarantees the continuity of care, coordinates patients, and regulates clinical workflow. ⋯ The comprehensive assessment of osteoarthritis includes evaluation of its effects on the patient's physical function and quality of life; formulating a treatment plan in collaboration with the patient and adapted to his or her comorbidities; providing advice on basic treatments and their risks and benefits; and carrying out an individually-tailored periodic review. Referral criteria are based on diagnostic confirmation, poor treatment response, and surgical evaluation.

The symptoms of osteoarthritis vary widely from patient to patient, depending especially on the localization on the disease. There is a poor correlation between radiological involvement and pain. In general, symptom onset is gradual and symptoms increase slowly but progressively. ⋯ In hand osteoarthritis, the most commonly affected joints are the distal interphalangeal joints, followed by the proximal interphalangeal joints and the trapeziometacarpal joints; the development of Heberden and Bouchard nodes is common; involvement of the trapeziometacarpal joint is called rhizarthrosis and is one of the forms of osteoarthritis that produces the greatest limitation on hand function. Osteoarthritis of the spine affects the facet joints and the vertebral bodies. Other, less frequent, localizations are the foot, elbow and shoulder, which are generally secondary forms of osteoarthritis.

Because of its low cost, availability in primary care and ease of interpretation, simple X-ray should be the first-line imaging technique used by family physicians for the diagnosis and/or follow-up of patients with osteoarthritis. Nevertheless, this technique should only be used if there are sound indications and if the results will influence decision-making. Despite the increase of indications in patients with rheumatological disease, the role of ultrasound in patients with osteoarthritis continues to be limited. ⋯ The indications for ultrasound, CT and MRI in patients with osteoarthritis continue to be limited in primary care and often coincide with situations in which the patient may require hospital referral. Patient safety should be bourne in mind. Patients should be protected from excessive ionizing radiation due to unnecessary repeat X-rays or inadequate views or to requests for tests such as CT, when not indicated.

The therapeutic management of patients with osteoarthritis aims to decrease pain and inflammation, improve physical function, and to apply safe and effective treatments. A patient-centered approach implies the active participation of the patient in the design of the treatment plan and in timely and informed decision-making at all stages of the disease. ⋯ The use of physical therapies, technical aids (walking sticks, etc.) and simple analgesics, opium alkaloids, and antiinflammatory drugs have demonstrated effectiveness in controlling pain, improving physical function and quality of life and their use is clearly indicated in the treatment of osteoarthritis. Conservative surgery and joint replacement is indicated when treatment goals are not achieved in specific patients.
