Knee Pain and Osteoarthritis: Why Your Knee Hurts and When to Seek Help

Knee Pain and Osteoarthritis: Why Your Knee Hurts and When to Seek Help

Knee pain is one of the most common reasons people visit a doctor, especially as they get older or become more physically active. For many patients, one possible cause is osteoarthritis of the knee, a condition where the joint gradually becomes painful, stiff, and harder to move.

At AIC Health Hub, we help patients understand what may be causing their knee pain and guide them toward proper consultation, rehabilitation, and long-term care.

What Is Knee Osteoarthritis?

Osteoarthritis is the most common type of arthritis. It happens when the protective cartilage inside the joint gradually wears down, causing pain, stiffness, swelling, and reduced movement. The knees are one of the most commonly affected areas because they carry much of the body’s weight during walking, standing, climbing stairs, and daily movement.

Knee osteoarthritis does not always happen overnight. It may begin as mild discomfort and slowly progress into recurring pain, stiffness, or difficulty doing everyday activities.

Common Symptoms of Knee Osteoarthritis

You may be experiencing knee osteoarthritis if you notice:

Pain when walking, standing, climbing stairs, or getting up from a chair
Knee stiffness, especially in the morning or after sitting for a long time
Swelling around the knee
A cracking, grinding, or clicking feeling when moving the knee
Difficulty fully bending or straightening the knee
Pain that improves with rest but returns with activity
Reduced confidence when walking or bearing weight on the affected leg

According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, osteoarthritis pain is often worse when using the joint and may improve with rest, while stiffness usually lasts less than 30 minutes after waking or resting.

Why Does Knee Osteoarthritis Happen?

Knee osteoarthritis may be linked to several factors, including:

Age-related joint changes
Previous knee injury
Excess body weight or obesity
Weak thigh, hip, or leg muscles
Repetitive stress on the knee
Family history of osteoarthritis
Poor movement patterns or joint alignment

Being overweight can increase pressure on the knee joint. This is why weight management is often recommended as part of knee osteoarthritis care, especially for patients who experience pain when standing, walking, or climbing stairs.

Is Knee Pain Always Osteoarthritis?

No. Knee pain can also come from ligament injuries, meniscus problems, tendinitis, bursitis, muscle weakness, nerve-related pain, or other joint conditions.

That is why proper assessment is important. A doctor or rehabilitation specialist may check your symptoms, walking pattern, knee movement, strength, swelling, medical history, and, when needed, request imaging or laboratory tests.

Can Physical Rehabilitation Help?

Yes. Exercise and physical rehabilitation are among the core treatments for knee osteoarthritis. Guidelines commonly recommend therapeutic exercise, strengthening, and low-impact movement to help reduce pain, improve flexibility, build muscle support, and improve daily function.

A rehabilitation plan may include:

Gentle knee mobility exercises
Strengthening for the thigh, hip, and leg muscles
Balance and stability training
Walking and movement retraining
Pain management strategies
Education on safe movement and joint protection
Home exercise guidance

The goal is not simply to “exercise more.” The goal is to move correctly, safely, and consistently based on your condition.

What Activities Are Usually Better for Knee Osteoarthritis?

Many patients benefit from low-impact activities, such as:

Walking at a comfortable pace
Stationary cycling
Water-based exercise
Gentle stretching
Strengthening exercises guided by a professional

It is important to start slowly. Some discomfort may happen when beginning an exercise program, but sharp pain, worsening swelling, or pain that does not settle should be checked by a healthcare professional. NICE guidance recommends therapeutic exercise tailored to the patient’s needs and notes that supervised exercise may be considered for people with osteoarthritis.

When Should You See a Doctor?

You should consider seeing a doctor or rehabilitation specialist if:

Your knee pain lasts for more than a few days
Pain keeps coming back
You have swelling, warmth, or difficulty walking
You struggle with stairs, standing, or getting up from a chair
Your knee feels unstable or gives way
Pain affects your sleep or daily activities
You are unsure if exercise is safe for your condition

Early assessment can help prevent worsening movement habits and may help you manage symptoms before they interfere more with daily life.
