Examination Overview
A doctor often discovers important information about the possible
causes of symptoms through a discussion about your medical history. During this
discussion, the doctor may ask questions such as the following:
- How long have you had symptoms? (Osteoarthritis usually develops
slowly.)
- Are your joints stiff in the morning? If so, for how
long?
- Have you tried any medicines that have helped the pain? If
yes, how much do they help?
- Do exercises help your pain or make it
worse? Which kinds of exercises have you tried? Have you tried bicycling or
swimming for your hips or knees?
- Has there been a pattern to your
symptoms? (Osteoarthritis symptoms typically begin on one side of the body and
often affect just one set of joints.)
- Do you have a family history
of arthritis?
- Do you have any general symptoms that seem to affect
your whole body, such as fatigue, weight loss, or fever? (Osteoarthritis
usually doesn't cause whole-body symptoms.)
- Has there been any
recent or past injury to the affected joints, especially a major joint injury
or injuries related to repetitive motion? (A recent injury may mean painful
symptoms are related to the injury, not an underlying disease.)
During the physical examination, the doctor will look at, feel, and
move each joint, evaluating it:
- For swelling, warmth, or
tenderness.
- For range of motion.
- To determine the
pattern of affected joints (such as one knee, both knees, knuckles, wrists, or
shoulders). Often, the pattern of joints affected can help a doctor tell the
difference between osteoarthritis and other types of arthritis such as
rheumatoid arthritis.
- To note any bony
knobs (osteophytic changes) on joints (especially the fingers).
The doctor will also look for any signs of unequal leg lengths,
muscle weakness, or muscle wasting.
During a physical examination, the doctor also will do an
evaluation of the lungs, heart, liver, and kidneys.
Why It Is Done
A medical history and physical examination are a normal and
important part of the evaluation of joint pain and stiffness.
Results
The key to diagnosing osteoarthritis is determining the pattern of
joints
that are affected
. For example, if you have symptoms in the set of
knuckle joints between the wrists and finger joints (metacarpal-phalangeal
joints), the balls of the feet (metatarsal-phalangeal joints), wrists, ankles,
or elbows, you probably have a different, inflammatory form of arthritis such
as rheumatoid arthritis.
Normal
A normal joint is not painful, tender, or swollen, has a full
range of motion, and appears structurally normal.
Abnormal
In an abnormal joint, an examination may detect pain or swelling
along with a bony hardness. Other abnormal findings that suggest osteoarthritis
include:
- Bony bumps on the finger joint closest to the
fingernail (Heberden's nodes
), bony bumps on the middle joint of
the finger (Bouchard's nodes
), or bony bumps at the base of the
thumb. - Tenderness and/or swelling in weight-bearing joints such as
the hips and knees.
- Pain, limited movement, and/or a creaking noise
or feeling (crepitus) that occurs when the joints are moved.
- Joints
that have been affected by injury or infection. These joints may also show
signs of bone or tissue damage.
What To Think About
Distinguishing between osteoarthritis and other types of arthritis
may be difficult based on individual joint symptoms but a pattern of symptoms
may indicate the type of arthritis.
