Bowlegged and Overweight

Bowlegs double the risk of knee arthritis in overweight patients. It increases the risk 5 fold for those who are very obese.

When a person is bowlegged the alignment shifts the knee’s load bearing axis medially (towards the inside of the knee) and since the medial compartment carries most of the knee’s load, increased force associated with obesity and bowlegged alignment is particularly destructive.
