Arthritis is one of the leading causes of joint pain and disability, affecting millions of people and making everyday activities more difficult. While there is no single cure for most forms of arthritis, the right treatment plan can help reduce pain, improve mobility, and support long-term joint health. Physical therapy (PT) is a key component of conservative arthritis management, helping individuals move more comfortably, strengthening the muscles that support their joints and maintaining an active lifestyle. This guide explains the different types of arthritis, common symptoms and causes, available treatment options, and how PT can help you better manage your condition and improve your overall quality of life.
Arthritis is an umbrella term used to describe more than 100 conditions that affect the joints and surrounding tissues, often resulting in pain, stiffness, swelling, and reduced mobility. While many people associate arthritis with aging, it can affect individuals of all ages, including children and young adults.1
Arthritis management refers to the combination of treatments and lifestyle strategies used to reduce pain, improve joint function, maintain mobility, and help individuals remain as active and independent as possible. Because there is no one-size-fits-all approach, management typically includes patient education. PT, exercise, medications, weight management, and, in some cases, injections or surgery, depending on the type and severity of arthritis.1
Arthritis is one of the most common chronic health conditions in the United States. Approximately 21.3% of U.S. adults, which is more than 53 million people, have been diagnosed with arthritis.2 Women are more likely than men to have arthritis, and nearly 90% of adults with arthritis are 45 years of age or older.2 Arthritis is also a leading cause of chronic pain, disability, and activity limitation, contributing to billions of dollars in healthcare costs and lost productivity each year.2
The effects of arthritis extend far beyond joint pain. Many individuals experience difficulty walking. Climbing stairs, exercising, working, performing household tasks, or participating in hobbies they once enjoyed. Over time, persistent pain and decreased activity can contribute to muscle weakness, reduced cardiovascular fitness, weight gain, anxiety, depression, and a lower overall quality of life.2 Fortunately, early diagnosis and a comprehensive treatment plan, including PT, can help manage symptoms, improve function, and support long-term joint health.
Although arthritis is often discussed as a single condition, it actually refers to a large group of diseases with different underlying causes. Some forms develop because of gradual joint degeneration, while others are caused by autoimmune diseases, metabolic disorders, or chronic inflammation. Understanding the specific type of arthritis is essential because treatment recommendations differ depending on the underlying cause.1
Osteoarthritis (OA) is the most common form of arthritis. It develops when the protective cartilage covering the ends of bones gradually breaks down, causing bones to rub against one another during movement.1 This loss of cartilage can lead to pain, stiffness, swelling, decreased range of motion (ROM), and the development of bone spurs over time. OA most commonly affects the knees, hips, hands, and spine.1
Rheumatoid arthritis (RA) is an autoimmune disease in which the immune system mistakenly attacks the lining of healthy joints. This ongoing inflammation can damage cartilage, bone, ligaments, and tendons if not treated early.1 Unlike OA, RA often affects multiple joints on both sides of the body and may also involve other organs, including the lungs, heart, eyes, and skin.1
Gout is an inflammatory form of arthritis caused by the accumulation of uric acid crystals within the joint. These crystals trigger sudden episodes of severe pain, redness, warmth, and swelling that frequently affect the big toe but may also involve the ankle, knee, wrists, or elbow\.1 While gout attacks can be extremely painful, appropriate medical treatment and lifestyle modification can help reduce the frequency of flare-ups.
Other inflammatory forms of arthritis include psoriatic arthritis, which occurs in some individuals with psoriasis, and axial spondyloarthritis, including ankylosing spondylitis, which primarily affects the spine and sacroiliac joints. These conditions are also driven by abnormal immune system activity and often require a combination of medication, exercise, and rehabilitation to preserve mobility and function.1
While not all cases of arthritis can be prevented, several factors increase an individual’s risk of developing the condition. Some risk factors cannot be changed, while others are modifiable.
Common risk factors include:
Symptoms of arthritis vary depending on the specific type of arthritis, the joints involved, and the severity of the disease. Some people experience mild symptoms that come and go while others develop persistent pain and stiffness that interfere with daily activities.
The most common symptoms include:
Symptoms differ between types of arthritis. OA pain typically develops gradually and may worsen with activity or prolonged weight-bearing. In contrast, inflammatory arthritis such as RA frequently causes prolonged morning stiffness, joint swelling, fatigue, and symptoms that occur in multiple joints simultaneously.1
Because arthritis symptoms tend to progress over time, persistent joint pain, swelling, or stiffness should not be dismissed as a normal part of aging. Early evaluation and treatment can help preserve joint function and improve long-term outcomes. 1
An accurate diagnosis is essential for developing an effective treatment plan. Since many forms of arthritis share similar symptoms, healthcare providers use a combination of medical history, physical examination, imaging, and laboratory testing to determine the specific type of arthritis affecting the patient.
If joint pain, stiffness, or swelling begins limiting your ability to work, exercise, or perform everyday activities, it is appropriate to schedule an evaluation with a physical therapist. Physical therapists (PTs) are trained to identify movement impairments, improve joint mechanics, and determine whether symptoms warrant referral to a physical for additional medical evaluation.
PTs are trained to refer out when your case may need additional medical help which can include;
Inflammatory conditions such as RA benefit from early diagnosis and treatment because prompt medical management can slow disease progression and reduce long-term joint damage.1
Depending on the suspected type of arthritis, your healthcare provider may recommend several diagnostic tests. These may include:
A physical therapist evaluates much more than the painful joint itself. The examination focuses on how arthritis affects movement, strength, balance, and everyday function.
A comprehensive PT evaluation typically includes:
The information gathered during this evaluation allows the physical therapist to develop an individualized treatment plan focused on reducing pain, improving mobility, restoring strength, and helping patients safely return to the activities that are the most important to them.
There is no single treatment that works for every type of arthritis. Instead, treatment is tailored to the specific diagnosis, severity of symptoms, and individual goals. In most cases, conservative (non-surgical) treatments are the first line of care and are aimed at reducing pain, controlling inflammation, preserving joint function, and slowing disease progression when possible.1
Many people are able to successfully manage arthritis symptoms with a combination of PT, medication, exercise, and healthy lifestyle changes.
If conservative treatment no longer provides adequate relief, a physician may recommend more advanced interventions, Depending on the types of arthritis and the affected joint, these may include corticosteroid or hyaluronic acid injections to reduce pain and inflammation, although the effectiveness varies spending on the condition being treated.3
For individuals with advanced joint damage and persistent pain, surgical procedures such as total joint replacement may be considered. Hip and knee replacement are among the most successful orthopedic surgeries and can significantly improve pain, mobility, and quality of life when conservative treatments are no longer effective.3
Managing arthritis involves more than treating joint pain, it requires a long-term approach that supports overall health and mobility. During flare-ups, balance activity with rest, using heat to ease stiffness or ice to reduce pain and inflammation, and continuing an individualized exercise program can help manage symptoms.4
Healthy lifestyle habits such as maintaining a healthy weight, getting adequate sleep, managing stress, and eating a balanced diet may also improve symptom control.2 Because chronic pain can affect emotional well-being, seeking support from family, friends, healthcare providers, or support groups is an important part of comprehensive arthritis management.
PT is one of the most effective conservative treatments for arthritis because it addresses the underlying movement impairments that contribute to pain and loss of function. Rather than simply treating symptoms, PTs help patients improve strength, flexibility, balance, joint mobility, and movement mechanics to reduce stress on affected joints and improve everyday function
At Confluent Health, our physical therapists develop individualized treatment plans based on your symptoms, diagnosis, and goals. Treatment may include therapeutic exercise, manual therapy, balance and gait training, education on joint protection, and personalized strategies to help you stay active and independent, many patients experience improved function, greater confidence with movement, and a better quality of life though consistent PT.
