Risks

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.

Infection:
About 1 of 100 people get aan infection in the hip. You'll need antibiotics for a while and one or more additional surgeries.5

Population: 1%

Hip dislocation:
In 5 of 100 people, the hip dislocates (the ball pops out of the socket). The hip may stabilize over time by avoiding some activities, but some people need more surgery.11 

Population: 5%

Death:
Hip replacement is a major operation that stresses your body. Fewer than 1 out of 100 people die during or after hip replacement surgery.6

Population: 0.5%

More surgery:
Five of 100 people have another operation within 10 years. This may be due to dislocation, infection, or loosening of the hip replacement. Ten of 100 people need to have the artificial hip replaced with a new one within 20 years.15

Population: 5%

Blood Clot (Thrombosis):
2 out of 100 people will experience a blood clot within 3 months after the surgery. A blood clot can stop the flow of blood from the legs back to the heart and lungs. 6
