Key Facts
✔ For knee osteoarthritis, physical activity and exercise are recommended to help manage knee pain and improve function, with advice tailored to individual needs and preferences. [1]
✔ Patellofemoral pain involves pain around or behind the kneecap during activities such as stairs and squatting. Combined hip and knee exercises are recommended to reduce pain and improve function. [2]
✔ People with osteoarthritis should be advised that joint pain may initially increase when they start therapeutic exercise. [3]
✔ Knee osteoarthritis exercise programmes should be individualised and progressive, with realistic goals and monitoring of the person’s response. [4]
✔ Go to an emergency department if your knee is badly swollen or has changed shape, you have fever with a red and hot knee, or your knee pain is caused by a major injury. [5]
30-Second Summary
Avoiding stairs is not automatically protecting your knee: for conditions such as knee osteoarthritis, adjusted activity and exercise are recommended rather than blanket inactivity. [1,3] Temporary reductions may form part of an individual plan, but neither continuing through pain nor avoiding stairs permanently is a rule for every painful knee. [1,5] Go to an emergency department if the knee is badly swollen or has changed shape, if fever accompanies a red and hot knee, or after a major injury. [5]
Introduction
The stairs at home can turn an ordinary day into a series of decisions. You reach the first step and wonder whether taking the lift would be more sensible. The uncertainty can follow you to work, the station or a weekend away.
What you want to know is whether avoiding stairs is protecting the knee. This article looks at that question through the demands of the task and the reasons an assessment might change the answer. It also explains what a comparison on a step can reveal, and where its limits lie.
Is avoiding stairs protecting the knee?
Pain on a staircase deserves attention, but it does not identify the cause by itself. Knee pain can arise from injury or several medical conditions, and treatment depends on the cause. [5] A temporary change in activity may be appropriate while the problem is assessed. That decision depends on the presentation, particularly after an injury. [1,5]
For people with knee osteoarthritis, some discomfort during exercise does not automatically mean that the joint is being damaged. Australian guidance recommends adjusting exercise to pain and ability while maintaining suitable activity. [1] That reassurance applies to osteoarthritis care, not automatically to a newly injured, swollen or unstable knee. [5]
There is an important difference between reducing a task temporarily and giving up on that task indefinitely. For knee osteoarthritis, guidance supports realistic activity goals, progressive exercise and regular review. [1,4] If the stairs at home matter to you, that goal belongs in the plan, even if the starting exercises happen elsewhere.
This does not prove that avoiding stairs itself damages the knee or inevitably reduces strength. The practical concern is whether a long-term restriction leaves a valued activity unaddressed. A plan should explain what you can do now, what needs assessment and how progress will be reviewed. [1,4]
Why going up and down can feel different
Going up involves raising your body to the next step; going down involves controlling the lowering movement. These are different tasks, so an assessment can examine them separately. Clinicians assessing patellofemoral pain may use squats and step-down tasks and examine hip and thigh strength alongside movement. [6]
Step height, pace, hand support and how you move through the knee and hip are useful variables to compare during an assessment. This is an application of individual task assessment, not a claim that one stair technique treats every knee condition. [1,6] Slower movement, for example, is something to compare rather than assume will always be easier.
One possible explanation for stair-related symptoms is patellofemoral pain, meaning pain around or behind the kneecap during activities that load the bent knee. Stairs and squatting are recognised examples. [2] Knee osteoarthritis is another possible cause, but injury and other joint conditions also need consideration. [5]
A change in comfort with a lower step or a rail can inform the examination. It cannot, on its own, establish a diagnosis or show that a particular muscle is weak. Patellofemoral pain assessment combines the symptom pattern, examination findings and exclusion of other causes. [6]
What matters beyond the painful step
The useful history includes where the pain is, when it began and whether there was a specific injury. Swelling, redness, heat, bruising, difficulty straightening, locking and giving way are also relevant symptoms. [5] The broader guide to knee pain covers several possible knee presentations.
For your consultation, describe the actual task: the stairs at home, a steep station staircase or the last few steps after a busy day. Explain whether the difficulty is going up, going down or both. These details make the activity limitation clearer, alongside the symptom history and examination. [6]
A quieter pain score is not the only useful goal. Knee osteoarthritis guidance also focuses on physical function and participation, with activities matched to the person’s priorities. [1] The related article on knee osteoarthritis and capability discusses symptoms, everyday function and what a scan can tell you.
Build a plan around the cause
Treatment should follow assessment rather than a universal instruction to rest or keep climbing. For knee osteoarthritis, strengthening and aerobic exercise are core options, with the programme adapted to capability and reviewed as it progresses. [3,4] Weight-management support, where appropriate, can form another part of osteoarthritis care. [3]
For patellofemoral pain, exercise targeting both the hip and knee is recommended. The 2018 consensus statement says: Combining hip and knee exercises is recommended to reduce pain and improve function. [2] This recommendation concerns people with patellofemoral pain; it does not establish the diagnosis in someone whose knee hurts on stairs.
A 2025 review combined 217 randomised trials involving 15,684 people with knee osteoarthritis. Aerobic exercise ranked favourably across pain, function, walking performance and quality of life, with moderate-certainty evidence supporting the overall conclusion. [7] Many comparisons relied on indirect evidence rather than head-to-head trials. The review did not establish that stair practice is superior to other rehabilitation. [7]
Education should explain the condition and the activity plan, but information alone is not a guaranteed solution. A nine-trial review of patellofemoral pain found low-credibility evidence that educational materials alone were less effective than exercise. [8] Clinician-delivered education alone produced similar pain and function outcomes to education plus exercise, with low or very low credibility evidence. [8]
Medicines or other medical treatments may also be relevant depending on the cause; a doctor can discuss those options. [5]
Modify the task with a clear purpose
Check with a doctor or physiotherapist before starting a new exercise programme for knee pain. If an injury has caused pain and swelling, avoid putting weight on the knee and seek appropriate assessment rather than practising stairs. [5] The suggestions below concern activity planning after relevant assessment, not a way to clear a new injury yourself.
For established knee osteoarthritis, activity modification can sit alongside exercise, pacing and realistic goals. [1] A clinician might compare a lower step, hand support, a different pace or fewer repetitions, using the response to help adjust the plan. These are examples of applying individual assessment, not a tested stair protocol or a guaranteed way to reduce pain. [1,6]
This is an illustrative case. Someone with assessed knee osteoarthritis wants to manage the stairs to an upstairs bedroom. In a supervised comparison, they describe a lower step with hand support as more manageable than the full-height step. That observation could inform the starting task, while a separate strengthening programme addresses the person’s assessed needs. [1,4]
The example does not establish that the rail corrected an injury or that the lower step is the right choice for another person. A useful comparison records the task and the response, then feeds back into the assessment. [6] The article on pain during exercise decisions examines the distinction between stopping, modifying, monitoring and seeking assessment.
For knee osteoarthritis, an activity log can record what you did and how it felt, helping your clinician review the plan. Exercise goals can then be adjusted as capability changes. [1] Further increases should follow the agreed plan and review, rather than one comfortable attempt. [1]
When to see a physiotherapist or seek medical care
A physiotherapy assessment is relevant when stair difficulty repeatedly limits daily activities or you need help choosing and progressing exercise. For patellofemoral pain, examination may include loaded movements and hip and thigh strength; osteoarthritis care also considers goals, support and falls risk. [1,6] A step comparison is one part of that assessment, rather than the whole explanation.
Go to an emergency department if your knee is badly swollen. A knee that has changed shape also needs emergency-department assessment. Pain caused by a major injury belongs in that urgent pathway too. [5]
Go to an emergency department if you have fever with a red and hot knee. Fever with new knee pain, redness and swelling also warrants urgent medical attention. Do not assume this is an ordinary exercise response. [5]
See a doctor if you cannot move the knee or cannot put weight on it. A knee that locks or gives way, or is very painful, also needs a doctor’s assessment. Do not keep testing those symptoms on the stairs. [5]
See a doctor if the pain is not improving after a few days. If you are unsure which service is appropriate, Healthdirect’s Australian nurse helpline is available on 1800 022 222. [5] New warning signs change the plan even when you already have an osteoarthritis diagnosis.
Key Takeaways
- Treat stair difficulty as a specific goal for assessment, rather than accepting a permanent restriction without review. [1,6]
- Compare task changes within an appropriate plan; a more comfortable step does not diagnose the cause. [6]
- Ask how exercise will progress towards the stairs you need in daily life. [1,4]
- Pause stair experiments and use the medical pathway when swelling, injury, instability or other warning signs change the picture. [5]

Frequently Asked Questions
Using support does not, by itself, establish that an injury has been corrected or concealed; it changes the task being assessed. [6] In knee osteoarthritis care, the home environment, support and falls risk are relevant to activity planning. [1]
Yes, knee osteoarthritis exercise can include strengthening, aerobic activity or water-based options rather than repeated stairs. [1,3] The choice should fit your assessment and goals, especially if returning to stairs remains important to you. [1]
Not routinely for a typical osteoarthritis presentation, which can usually be assessed clinically. [1,3] A recent injury or unusual symptoms can change the assessment and the need for investigations, so this is not a rule against imaging. [5]
Not necessarily in an agreed osteoarthritis programme, because some discomfort can occur when exercise begins. [1,3] That guidance does not mean you should deliberately provoke pain or continue through a new, unexplained symptom. [5]
