Osteoarthritis is a common joint condition that can cause pain, stiffness, and difficulty with everyday movement—but there are many ways to manage symptoms and protect function.
Osteoarthritis, often called OA, is the most common type of arthritis. It develops when the tissues within a joint gradually change over time. The cartilage that normally helps cushion the ends of bones may become thinner or damaged, and other parts of the joint can also be affected.
Osteoarthritis most commonly affects the:
- Knees
- Hips
- Hands and fingers
- Spine
- Feet
Although osteoarthritis becomes more common with age, it is not simply a normal or unavoidable part of getting older. Many factors can influence whether OA develops and how much it affects a person.
What Does Osteoarthritis Feel Like?
Symptoms can vary from mild to severe.
Common symptoms include:
- Aching or soreness in the joint
- Pain that becomes worse with activity
- Stiffness after resting
- Morning stiffness
- Reduced range of motion
- Joint tenderness
- Swelling
- Difficulty walking, climbing stairs, gripping, or completing daily activities
- Grinding, clicking, or crackling sensations with movement
- Changes in the shape or appearance of a joint over time
Symptoms may fluctuate. Some people experience periods when pain is relatively mild and other times when symptoms temporarily worsen.
Why Does Osteoarthritis Happen?
Osteoarthritis involves more than simple “wear and tear.”
Changes can occur in the:
- Cartilage
- Bone
- Joint lining
- Ligaments
- Muscles surrounding the joint
Several factors may increase the likelihood of developing osteoarthritis.
These include:
- Increasing age
- Previous joint injury
- Repetitive stress on a joint
- Family history or genetics
- Obesity or excess body weight
- Muscle weakness
- Certain joint abnormalities
- Previous joint surgery
- Some occupational or sports-related activities
Having a risk factor does not mean a person will automatically develop severe osteoarthritis.
How Is Osteoarthritis Diagnosed?
A healthcare professional may ask about:
- Where the pain occurs
- When symptoms started
- Activities that make the pain better or worse
- Morning stiffness
- Previous injuries
- Joint swelling
- Difficulty performing daily activities
- Previous treatments
A physical examination may evaluate:
- Range of motion
- Joint tenderness
- Swelling
- Strength
- Walking and balance
- Joint stability
- Functional limitations
X-rays may sometimes be used to look for changes associated with osteoarthritis.
However, the severity seen on an X-ray does not always match the amount of pain a person experiences. Someone may have significant changes on imaging with relatively little pain, while another person may experience substantial symptoms with less dramatic imaging findings.
What Can Help Osteoarthritis Pain?
Treatment is usually focused on:
- Reducing pain
- Maintaining or improving movement
- Strengthening muscles around the joint
- Improving daily function
- Supporting independence
- Preventing unnecessary disability
A combination of approaches is often more helpful than relying on one treatment alone.
Exercise and Movement
Regular movement is one of the most important parts of osteoarthritis management.
Appropriate exercise may help:
- Reduce pain
- Improve joint movement
- Strengthen muscles
- Improve balance
- Increase endurance
- Make daily activities easier
Activities may include:
- Walking
- Swimming
- Water exercise
- Cycling
- Strength training
- Range-of-motion exercises
- Tai chi
- Gentle stretching
Exercise should be adjusted to your abilities and medical conditions.
Some temporary soreness can occur when beginning a new activity program, but persistent or severe worsening of pain should be discussed with a healthcare professional.
Strengthening the Muscles Around the Joint
Strong muscles can help support and stabilize an arthritic joint.
For example, strengthening the muscles around the thighs and hips may improve function in people with knee osteoarthritis.
A physical therapist can help design an exercise program that is appropriate for your individual needs.
Weight Management
For people who are overweight or obese, reducing excess body weight may decrease stress on weight-bearing joints such as the knees and hips.
Even modest weight loss may improve mobility and reduce symptoms for some people.
Weight management is not appropriate as the sole explanation or treatment for joint pain. It should be considered as one part of a broader health and pain-management plan when appropriate.
Physical Therapy
Physical therapy may help people with osteoarthritis improve:
- Strength
- Flexibility
- Walking
- Balance
- Joint mobility
- Body mechanics
- Confidence with movement
A physical therapist can also recommend appropriate exercises and help modify activities that aggravate symptoms.
Occupational Therapy
An occupational therapist may help people continue daily activities despite arthritis.
Strategies may include:
- Joint-protection techniques
- Adaptive equipment
- Modified household activities
- Energy conservation
- Hand or wrist supports when appropriate
- Strategies for dressing, cooking, bathing, or working
Heat and Cold
Some people find temporary relief from heat or cold.
Heat
Heat may help:
- Reduce stiffness
- Relax muscles
- Make movement more comfortable
Examples include warm showers, heating pads, or warm compresses.
Cold
Cold may help temporarily reduce:
- Pain
- Swelling
- Discomfort following activity
Avoid placing extreme heat or cold directly on the skin, and use additional caution if you have decreased sensation.
Assistive Devices
Some people benefit from devices that reduce pressure on painful joints or make movement safer.
Examples may include:
- Canes
- Walkers
- Braces
- Shoe inserts
- Grab bars
- Raised toilet seats
- Adaptive kitchen or household tools
A healthcare professional or therapist can help determine which device is appropriate.
What About Medication?
Medication may be used along with exercise and other non-medication strategies.
Depending on the joint involved and your medical history, a healthcare professional may discuss options such as:
- Acetaminophen
- Nonsteroidal anti-inflammatory drugs, or NSAIDs
- Topical NSAIDs
- Other topical pain-relief products
- Certain other non-opioid medications
Some medications are not appropriate for everyone.
NSAIDs, for example, may require additional caution in people with:
- Kidney disease
- Heart disease
- High blood pressure
- History of stomach ulcers
- Gastrointestinal bleeding
- Certain medication interactions
Discuss medication risks and benefits with your healthcare professional.
Joint Injections
For some people, healthcare professionals may consider injections when other treatments do not provide adequate relief.
Options may vary depending on the joint and individual circumstances.
Joint injections are not appropriate for everyone, and their benefits may be temporary.
Ask your healthcare professional about the potential benefits, risks, and alternatives.
What About Opioids?
Opioids are generally not considered a first-line treatment for osteoarthritis pain.
For most people, treatment should emphasize approaches such as:
- Exercise
- Strengthening
- Physical therapy
- Weight management when appropriate
- Non-opioid medications
- Other evidence-based treatments
If an opioid is considered, the potential benefits should be carefully weighed against risks such as:
- Sedation
- Constipation
- Falls
- Physical dependence
- Opioid use disorder
- Respiratory depression
- Overdose
When Is Surgery Considered?
Some people develop severe osteoarthritis that significantly limits mobility, independence, sleep, or quality of life despite appropriate nonsurgical treatment.
In these situations, a healthcare professional may recommend evaluation by an orthopedic specialist.
Joint replacement surgery is most commonly performed for severe osteoarthritis of the:
- Hip
- Knee
Surgery is generally considered after evaluating symptoms, functional limitations, overall health, and response to nonsurgical treatments.
Focus on Function
Pain intensity is important, but it is not the only way to measure whether treatment is helping.
Consider asking:
“What am I able to do now that was difficult before?”
Functional goals may include:
- Walking farther
- Climbing stairs
- Getting out of a chair more easily
- Sleeping more comfortably
- Playing with children or grandchildren
- Cooking or completing household tasks
- Exercising
- Returning to hobbies
- Becoming more independent
Tracking functional improvement can help you and your healthcare team determine whether your treatment plan is working.
Questions to Ask Your Healthcare Professional
Consider asking:
- Is osteoarthritis likely causing my joint pain?
- Would physical therapy help me?
- What exercises are appropriate for my joint?
- Are there activities I should modify?
- Would weight management help my symptoms?
- What non-medication treatments can I try?
- Which pain medications are safest for me?
- Would a brace or assistive device help?
- Are injections appropriate for my condition?
- When should I consider seeing an orthopedic specialist?
When Should You Seek Medical Attention?
Contact a healthcare professional if joint pain:
- Persists or continues to worsen
- Significantly limits daily activities
- Causes repeated falls or difficulty walking
- Is associated with increasing swelling
- Does not improve with reasonable self-care
- Develops after an injury
Seek more urgent medical evaluation for symptoms such as:
- A joint that becomes suddenly very red, hot, and swollen
- Severe pain with fever or chills
- Inability to bear weight after an injury
- A visibly deformed joint
- Sudden severe pain without an obvious explanation
These symptoms may represent conditions other than osteoarthritis and deserve prompt evaluation.
Living Well With Osteoarthritis
Osteoarthritis is a long-term condition, but symptoms and function can often improve with an individualized management plan.
The goal is not simply to protect the joint by avoiding activity.
In many cases, safe movement is part of the treatment.
Small changes such as gradually increasing activity, strengthening muscles, improving sleep, using appropriate assistive devices, and setting realistic functional goals can make a meaningful difference over time.
Instead of focusing only on:
“What is my pain number today?”
consider asking:
“What activities are important to me, and what can help me continue doing them?”
That question can help shift pain care toward maintaining independence, movement, and quality of life.
