Bowlegs can be progressive if not treated. Check whether your joints are more flexible than others. If so, you have a hyperlaxity syndrome wherein your deformity
would progress over time. And yes, bow legs can cause secondary osteoarthritis
at a later date i.e faster than an average individual would take to develop the same. I would advise you to consult an Orthopaedic Surgeon
to assess the severity of bowing and need for intervention. You would require standing X-Rays of both legs in two views.
