There are risks with every operation. If you have heart, kidney or lung disease, the chance of having a medical complication with surgery is higher.

If you are a smoker or are overweight the chance of having a medical complication is higher. But, if you are able to quit smoking and or lose weight chance of having a complication with surgery goes down.

Not being able to move properly:
After your hip replacement you will have pain. However this pain continues to improve on a daily basis for up to 6-12 months. Some people still have a little pain that limits their ability to move, but most people find it is less pain than what they had prior to surgery. 

Difference in Leg Length:
After the operation, one leg may be slightly longer than the other. This might result in knee discomfort. This can usually be alleviated with an insert in your shoe.

Damage to the nerve:
A nerve can be damaged during surgery. This can result in partial paralysis of the leg. You may not be able to raise your foot. This usually recovers, but it can take several months.
