If you're experiencing symptoms of any form of arthritis, it's probably best to see a doctor. Some secondary symptoms of arthritis, such as fever, weight loss, rash and difficulty breathing, can be an indication of another problem, so it's important to have a doctor properly diagnose your condition. If your doctor does determine that it may be arthritis, you may be referred to a rheumatologist, or an arthritis specialist. It's important to get medical attention as early as possible to prevent potential bone loss or loss of range of motion.
Arthritis Diagnosis
Doctors diagnose arthritis with a medical history and physical exam to check for joint inflammation and deformity. Your doctor may also order lab work like blood, urine and joint fluid tests. X-rays are commonly used to check for cartilage loss in the affected joints, narrowing of the space between bones and the existence of nodules. Following the initial diagnosis, x-rays are also used to mark your arthritis progression.

Dr. Thomas P. San Giovanni, MD , Orthopedic Surgery, answered on behalf of Baptist Health South FloridaTo diagnose hindfoot arthritis, the doctor will examine your foot and may ask you to walk so he or she can observe your gait. X-rays will help reveal any degenerative changes. Additional tests such as MRI may also be called for to help determine any other abnormalities or sources of pain. -

Dr. Christopher W. Hodgkins, MD , Orthopedic Surgery, answered on behalf of Baptist Health South FloridaIn order to diagnose arthritis of the midfoot, the doctor will examine your foot and may order imaging studies. Weight-bearing x-rays can demonstrate loss of joint space in the midfoot joints, which is characteristic of arthritis. -

Dr. Thomas P. San Giovanni, MD , Orthopedic Surgery, answered on behalf of Baptist Health South FloridaIn the foot, arthritis most frequently occurs in the big toe, although it is also often found in the midfoot and ankle. A doctor can usually diagnose arthritis based on symptoms and standard x-rays.

Dr. Mehmet Oz, MD , Cardiology (Cardiovascular Disease), answeredAn x-ray can show the damage done to the bones of the joint due to loss of protective cartilage and bones rubbing directly against each other.

Dr. Mehmet Oz, MD , Cardiology (Cardiovascular Disease), answeredCartilage does not show up on x-rays. X-rays do show changes in the space between bones, such as in the knee joint, if cartilage is worn away by arthritis. This video gives more information on the knee and arthritis.

Dr. Grant Cooper, MD , Physical Medicine & Rehabilitation, answeredThe degree of severity of arthritis on an X-ray often does not correlate with symptoms. A person with a terrible looking X-ray of the knee may be completely symptom-free. Likewise, a person who shows minimal arthritis on an X-ray may be experiencing severe pain. This does not mean that one person is stoic and the other is a complainer. Different people have higher or lower thresholds for pain, depending on their body biochemistry and the synapses within their brain. Many factors influence the pain threshold in a given individual, including social support, depression, painful stimuli, and other potential biochemical and neuromodulating factors.
Someone who has severe cartilage degeneration may not have reached the point where the surrounding structures have become irritated and inflamed. If only cartilage is involved, there will be no pain because cartilage doesn't have any nerve endings. By contrast, the person with minimal X-ray findings of cartilage degeneration may just be unlucky enough to have the cartilage degrade in a pattern that allows pressure to be placed on the surrounding structures, leading to irritation and inflammation. Perhaps the synovium was already inflamed, or perhaps the bone was already compensating for increased pressure, and a tiny bone spur hooked a piece of the joint capsule or irritated a ligament. -

Dr. Grant Cooper, MD , Physical Medicine & Rehabilitation, answeredThe presence of asymptomatic findings of arthritis on an X-ray should be taken as a warning that the joint is not healthy and will probably become painful if you don't start taking better care of it.
A person with no clinical symptoms and X-ray findings of arthritis should be treated in the same way as someone with no symptoms and no X-ray findings. Both should eat right, exercise, and take the appropriate supplements. The key difference is that the person with X-ray findings may be at greater risk of developing symptoms sooner, and should take preventative measures as soon as possible. Routine screening with X-rays to look for arthritis damage is definitely not indicated because they expose the patient to unnecessary radiation and are costly.
Noticing signs of arthritis on X-ray should prompt a greater sense of urgency for the patient to take steps to reduce the risk of developing worsening arthritis, which likely will eventually lead to pain and suffering if it is not appropriately managed. -

Dr. Grant Cooper, MD , Physical Medicine & Rehabilitation, answeredIn addition to X-rays, CT scans, and/or MRIs, your doctor might order blood tests to help rule out infection, types of arthritis other than osteoarthritis, cancer, and other problems. Most people with straightforward signs and symptoms of arthritis may not require more than an X-ray. However, your physician will make that determination in order to help ensure that a more serious underlying disorder does not go undiagnosed and untreated.
