You'll need to ask your surgeon this question to know for sure. Every patient and every scar is slightly different. Sometimes the anatomy determines where and how an opening is made. Before cutting the patient open, X-rays are taken and the surgeon uses his or her hands to feel where each muscle, tendon, and bone is located.

A curved incision is often used to help the surgeon remove the diseased joint. The capsule around the joint must be cut and the hip dislocated first before removal. A curved incision helps with this process. If the head of the femur is larger than expected, the incision may have to be made longer to get it out.

Sometimes the size of the surgeon's hands makes a difference. Doctors joke about finding a surgeon with small, but strong hands. There is some truth to this idea!
