Hip replacement surgery may result in blood clots in leg veins, infection, hip joint fracture and a difference in the lengths of the legs, according to Mayo Clinic. In rare cases, hip replacement surgery may cause gradual hip joint loosening, which eventually leads to hip pain.
Hip replacement surgery may result in the formation of blood clots in the veins of the legs, explains Mayo Clinic. This complication is even worse when a clot moves from the blood vessel to important body organs such as the brain and the heart. To ensure that the surgery does not render the patient vulnerable to this complication, the patient may take blood-thinning prescription drugs following the surgery. Infections in people who have had hip replacement surgery mostly attack either an incision the surgeon makes during the surgery or the deep-lying tissue located adjacent to the replacement hip. Although such infections are treatable by use of antibiotics, surgical replacement of the prosthesis may be necessary in the treatment of serious infections.
Hip replacement surgery may cause a complication in which one leg is longer than the other; although this happens rarely due to precautions that surgeons take, explains Mayo Clinic. Additionally, hip muscle weakness may also cause a difference in leg lengths. Fractures in the hip joint resulting from hip replacement surgery may be large or small. While the smaller ones may heal without treatment, fractures that are large in size may necessitate treatment using pins, wires or bone grafts.
