There are possible risks and complications associated with anesthesia, including respiratory or cardiac malfunction. Other complications include the possibility of:
- Infection requiring antibiotics and in some cases hospitalization
- Infection occurring around the joint years after the surgery
- Blood clots in the legs (deep vein thrombosis), which can dislodge and move to the lungs (pulmonary embolism)
- Injury to nerves or blood vessels
- Loosening or dislocation of the prosthetic devices
- Joint stiffness
Risks can be reduced by following the surgeon's instructions before and after surgery.
