Osteoarthritis
Example Case
A 66-year-old client visits the clinic with recurring knee pain and morning stiffness.
Initially, the discomfort appeared only after long walks. However, over the past year, the client has gradually become less active.
“My doctor said I have osteoarthritis in my knee. The X-ray shows wear and tear, so I’m worried that walking will make it worse. I’ve already stopped going on my usual walks because I don’t want to damage the joint any further.”
Now, even climbing stairs and getting up from a chair feel harder. The client believes the knee is simply wearing out. But does osteoarthritis really mean the joint should be used less? That is the first piece of the puzzle.
Subjective Symptoms
The client reports:
- Knee pain during walking and stairs
- Stiffness after sitting for long periods
- Mild morning stiffness
- Reduced confidence using the affected leg
- Less physical activity than before
- Fear that exercise will accelerate joint damage
Interestingly, the client notices that the knee often feels stiff at first but becomes easier after moving for several minutes. This suggests that movement itself may not be the enemy.
What It May Feel Like
People with osteoarthritis may notice:
- Joint pain during or after activity
- Stiffness after rest
- Reduced range of motion
- Swelling around the joint
- Grinding or clicking sensations
- Reduced strength around the affected area
- Difficulty with stairs, walking or prolonged activity
Symptoms can vary considerably. Some people have obvious changes on X-ray but very little pain. Meanwhile, others experience significant symptoms with relatively modest structural changes. Therefore, an X-ray tells only part of the story.
Objective Findings
During assessment, the therapist may identify:
- Reduced knee range of motion
- Discomfort during squatting or stairs
- Reduced leg strength
- Mild joint swelling
- Tenderness around the knee
- Difficulty with repeated sit-to-stand movements
For example, our client can walk comfortably for short distances. However, pain and fatigue increase during repeated stairs and longer walks. This provides an important clue: function depends not only on the joint itself, but also on strength, confidence and physical capacity.

What Could It Be Related To?
Osteoarthritis is a joint condition involving changes in cartilage, bone and other tissues within and around the joint. It commonly affects the knees, hips, hands and spine. However, describing osteoarthritis simply as “wear and tear” can be misleading. The joint is not a machine part that inevitably wears away every time it moves. Instead, symptoms may be influenced by:
- Changes within the joint
- Local inflammation or sensitivity
- Reduced muscle strength
- Lower physical activity
- Previous joint injury
- Changes in movement and loading
- Increased pain sensitivity
In other words, structural change matters, but it is not the whole explanation for pain.
Possible factors include:
- Increasing age
- Previous joint injury
- Reduced muscle strength
- Higher body weight in some individuals
- Repetitive or demanding joint loading
- Genetics
- Reduced physical activity
- Other metabolic or health factors
Importantly, movement itself is not automatically harmful. In fact, appropriate physical activity can help maintain strength, mobility and function.
Therefore, avoiding movement completely may create another problem: the joint may become stiffer while the surrounding muscles become weaker.
The assessment aims to determine:
- Which activities reproduce symptoms
- How much movement is available
- Whether strength has declined
- How pain affects daily function
- Which activities can still be performed comfortably
- Whether symptoms suggest another condition requiring investigation
The therapist should also ask:
How far can the client walk?
Can they climb stairs?
Can they rise from a chair?
What activities have they stopped doing because of fear?
The goal is not simply to measure joint degeneration. It is to understand what the person can still do and what can be improved.
Management may include:
- Regular physical activity
- Progressive strengthening
- Joint mobility exercises
- Gradually increasing walking or functional activity
- Weight management when relevant
- Education about pain and joint loading
- Manual therapy as an adjunct when appropriate
- Medical management when symptoms require it
Initially, exercise may need to begin at a comfortable level. For example, the client may start with shorter walks, sit-to-stand exercises and gentle strengthening. Then, as tolerance improves, walking distance and resistance can gradually increase.
Some discomfort during or after exercise may occur. However, that does not automatically mean the joint is being damaged. The important question is whether symptoms remain manageable and function improves over time.
How Does It Usually Recover?
Osteoarthritis itself is a long-term condition, so recovery does not necessarily mean making the joint look normal again on an X-ray. Instead, treatment focuses on improving symptoms, strength and everyday function. At first, the client may notice small changes: less stiffness in the morning or greater confidence using stairs. Then, over time, consistent exercise and appropriate activity can improve the joint’s functional capacity. For our client, successful management may mean being able to:
- Walk regularly again
- Climb stairs with greater confidence
- Rise from chairs more easily
- Maintain leg strength
- Continue hobbies and social activities
- Reduce the impact of pain on daily life
Flare-ups may still occur. However, a flare-up does not necessarily mean the arthritis has suddenly become worse. Instead, activity can often be temporarily adjusted before gradually returning to the usual level. Persistent swelling, sudden major loss of movement, unexplained fever, severe night pain or rapidly worsening symptoms should prompt further medical assessment.
Your Body Talks. Learn to Listen.
A scan may show change. But change does not mean the joint is finished. Pain can influence how much you move. And how much you move can influence how strong and capable you remain. Osteoarthritis may change the joint. It does not have to take away the life around it.
Ask it. Even if you think it’s a ridiculous question.
Someone else has probably wondered exactly the same thing.
