Will my terrible bowed leg deformity effect my outcome?

Bowed leg and knocked knee deformity are common in severe arthritis of the knee.  Correcting the deformity at the time of surgery is typical and a routine part of knee replacement surgery.  Severe angular deformities can make the surgical procedure more complex.  Occasionally the routine physical therapy protocol is modified as a result of the more complex procedure.  Additionally once the angular deformity is corrected the patient may perceive the corrected knee has produced a longer leg.  This perceived leg length inequality typically improves over time or in certain situations is corrected once the opposite knee is corrected.
