Dr. Mayur Rabhadiya
Knee arthritis can affect both knees, but the severity, symptoms and treatment needs are not always equal. One knee may be more painful, more deformed or more limiting, and management should reflect each knee’s pattern as well as the patient’s overall walking ability and health.
Dr. Mayur Rabhadiya explains how bilateral knee arthritis is assessed and how decisions are made about non-surgical care, staged surgery or simultaneous bilateral replacement.

Quick Answer: How Is Arthritis in Both Knees Treated?
Assess each knee separately and the patient’s overall mobility
Use exercise, strength, weight management and medication for both knees when appropriate
Treat the more symptomatic knee first if the disease is unequal
Consider injections selectively and separately for each knee
Consider staged or simultaneous replacement only when both knees are severely disabling
Base surgical timing on health, rehabilitation capacity and patient goals
Why Both Knees May Be Affected
Primary osteoarthritis often affects both knees because age, genetics, body weight, metabolic health and lifelong loading influence both joints. The pattern may still be asymmetric. Previous injury, fracture, meniscal surgery, ligament damage or deformity can make one knee progress faster.
Symptoms of Bilateral Knee Arthritis
Pain in both knees during walking or standing
Difficulty with stairs and chair rise
Reduced walking distance and slower pace
Stiffness after sitting or waking
Swelling in one or both knees
Dependence on handrails or walking aids
Difficulty deciding which leg to lead with
Reduced confidence and higher fall risk
How Both Knees Are Assessed
Assessment compares pain, movement, swelling, alignment, stability and muscle strength in each knee. The hip, spine, balance and general medical fitness are also important because bilateral symptoms may reduce mobility more than one-sided disease. Weight-bearing X-rays may show different stages or compartment patterns in the two knees.

Non-Surgical Treatment for Both Knees
Exercise should strengthen both legs, hips and trunk and may include cycling, walking progression, balance, mobility and functional training. When both knees are painful, low-impact exercise and supervised progression may be easier than repeated stairs or deep squats. A walking aid can improve confidence and reduce load.

Can Both Knees Be Injected?
Injections may be considered in one or both knees after assessment. The decision depends on symptom severity, swelling, arthritis stage, medical history, previous response and the specific injection. Bilateral injections should not be treated as an automatic routine, and no injection can guarantee cartilage regrowth or prevent future replacement.
Which Knee Should Be Treated First?
If one knee is clearly more painful or disabling, treatment often starts there. Improving the worse knee can make rehabilitation and daily activity easier. When both knees are similarly affected, the choice depends on patient preference, alignment, strength, home support and whether surgery is being considered.
Staged Bilateral Knee Replacement
Staged surgery means replacing one knee and allowing recovery before operating on the other. It may be preferred when medical risk, age, rehabilitation capacity or unequal disease makes simultaneous surgery less suitable. The interval is individual and depends on recovery, health and function.
Simultaneous Bilateral Knee Replacement
Simultaneous bilateral replacement means both knees are replaced during one anaesthetic. It may reduce the number of hospital admissions and combine rehabilitation, but it is a larger physiological stress and is not appropriate for every patient. Careful selection is required based on cardiovascular, respiratory, kidney and general medical fitness, as well as home support and rehabilitation capacity.

Does Robotic Assistance Apply to Both Knees?
Robotic assistance can be used to support planning and execution for each knee. Each knee is assessed independently because deformity, bone anatomy and ligament balance may differ. The robot does not operate independently; the surgeon remains responsible for all decisions and the procedure.

When Should Bilateral Symptoms Be Reviewed?
Walking and independence are progressively declining
Both knees frequently disturb sleep
The patient is relying heavily on pain medication
Falls or near-falls are increasing
One knee has become markedly more swollen or painful
Non-surgical treatment no longer provides acceptable function
Frequently Asked Questions
Do both knees progress at the same speed?
No. One knee may remain mild while the other becomes advanced.
Can both knees improve without surgery?
Yes. Strength, weight management, activity planning and medication can improve overall function.
Is it better to replace both knees together?
Not universally. Simultaneous and staged surgery each have advantages and risks, and patient selection is essential.
Can I inject both knees on the same day?
Sometimes, but the injection type, medical history and clinical need should be reviewed individually.
Which knee should be replaced first?
Usually the more painful or functionally limiting knee, unless other clinical factors suggest a different sequence.
