Why perimenopause affects your knees and what helps
Nicola Tik
Knee pain during perimenopause is more common than many people expect, and it often appears without any obvious injury or change in activity. Understanding why the knees become more reactive during this hormonal transition makes it easier to manage the discomfort and respond to it in a way that supports the joint rather than working against it.
Oestrogen, the hormone that regulates many of the body's systems beyond reproduction, plays a direct role in maintaining the health of the cartilage, ligaments, and connective tissue of the knee. The knee is a load-bearing joint that absorbs significant force with every step, and it relies on these structures to distribute that load effectively and protect the joint surfaces from wear.
During perimenopause, fluctuating oestrogen affects the quality and resilience of the cartilage and connective tissue of the knee in ways that make the joint more reactive and less tolerant of load than it would be during periods of hormonal stability. The cartilage that cushions the knee joint becomes less well maintained, the ligaments that support it become less consistent in their resilience, and the synovial fluid that lubricates the joint becomes less reliable. The result is a knee that responds more readily to activity, sustained positions, and load changes than it did previously.
Knee pain during perimenopause often feels different from knee pain caused by a specific injury or overuse. It tends to be more variable, less clearly connected to a particular activity, and sometimes present without any obvious trigger. Many people notice that the knees feel stiff and achy on waking, more reactive after sustained sitting or standing, and less predictable in how they respond to the same level of activity from one day to the next.
The inner knee, the front of the knee, and the area around the kneecap are the most commonly affected regions during perimenopause. Stairs, prolonged walking, and getting up from a seated position are the activities that most commonly provoke discomfort, because they place the knee under a combination of load and movement that the more reactive joint finds harder to manage than it used to.
This variability is a direct consequence of fluctuating oestrogen rather than structural damage, and understanding it as such makes it easier to adjust activity and expectations without becoming overly cautious about movement, which tends to make knee symptoms worse rather than better over time.
Keeping the knee gently mobile during perimenopause is more important than resting it. Sustained inactivity allows the joint to stiffen and the surrounding muscles to weaken, which reduces the support available to the knee and makes it more vulnerable to load when activity resumes. Consistent gentle movement, on the other hand, maintains joint lubrication, keeps the surrounding muscles engaged, and moderates the pain sensitivity that fluctuating oestrogen produces.
On days when the knees are more reactive, shorter and lower-impact movement sessions are more useful than either stopping altogether or pushing through significant discomfort. Walking on flat surfaces, gentle cycling, and swimming all maintain movement through the knee without the impact load that stairs or running involve, and are worth prioritising on more difficult days.
Warmth applied to the knee before activity, and gentle movement immediately afterwards, eases the stiffness and joint sensitivity that builds during rest and makes the transition in and out of activity more comfortable.

The muscles of the quadriceps, at the front of the thigh, and the hamstrings, at the back, play a central role in protecting the knee by absorbing load and stabilising the joint during movement. During perimenopause, when the cartilage and connective tissue of the knee are more reactive, having well-maintained and strong surrounding muscles becomes particularly important as a way of reducing the demand placed directly on the joint structures.
Strength-based movement that engages the quadriceps, hamstrings, and the muscles of the hip and pelvis supports the knee by distributing load more broadly and improving the joint's tolerance of everyday activity. Bodyweight exercises, resistance bands, walking on varied terrain, and any activity that involves the legs working against some form of load all contribute to maintaining the muscular support that the knee relies on during this hormonal transition. Building this gradually rather than suddenly is important, because the knee during perimenopause is more reactive to unaccustomed load than it would be at other hormonal stages.
Because knee symptoms during perimenopause are variable, adjusting activity based on how the joint is responding on a given day tends to work better than applying the same approach regardless of how the knee is feeling. On days when symptoms are more prominent, reducing impact, breaking up longer periods of standing or walking with rest, and avoiding sustained positions that load the knee at a fixed angle all help manage reactivity without stopping activity altogether.
Supportive footwear that cushions the impact load through the knee during walking makes a meaningful difference to how the knee manages sustained activity on more reactive days. On days when the knee is particularly sensitive, avoiding prolonged kneeling and sustained squatting reduces the direct compressive load on the joint and gives it a genuine rest between more active periods.
Your VIDA pain check-in is a good way to track how knee symptoms are shifting over time and to notice patterns in when the joint tends to be more or less reactive.
