Causes of hip joint pain that may require hip replacement

Plus, what makes someone a good candidate for hip replacement surgery?

Chronic hip pain can prevent you from doing the activities you love and even cause discomfort when you’re trying to relax or sleep. Depending on the cause of your hip joint pain, the treatments you’ve tried, and your overall health, a hip replacement may be an option.

“When we see someone who has substantial hip discomfort and associated joint damage, and nonsurgical things have stopped providing them relief from their symptoms,” said Gregory Polkowski, MD, an adult reconstructive surgeon with Vanderbilt Orthopaedics, “that’s when we think hip replacement is indicated.”

Causes of hip joint pain and deterioration

The most common condition that causes hip joint pain and damage is chronic degenerative osteoarthritis, Polkowski said. The arthritic process can result in cartilage destruction. The second most common cause is avascular necrosis, also called osteonecrosis. An interruption or reduction in the blood supply to the hip bone causes the tissue to deteriorate or die, Polkowski explained.

Additionally, rheumatoid arthritis, which is an autoimmune disease, and post traumatic arthritis, a condition that can develop after a fracture, can both cause damage that may eventually necessitate a hip replacement. Structural hip problems like hip dysplasia, where the hip socket is too shallow to accommodate the femoral head, or ball, can also create the need for surgery.

What makes someone a good candidate for surgery?

Nonsurgical interventions can offer potential pain relief, Polkowski said. But they can’t fix the underlying arthritis or reverse joint damage. So if nonsurgical treatments have stopped working for someone, that’s when surgery becomes a consideration.

Patients are good candidates for joint replacement when their pain affects their quality of life. “We don’t make the judgment purely on how the joint looks on X-ray,” Polkowski explained. “It has to be a combination of joint damage and chronic pain that really limits them from doing the things that they need to be doing.” Those limits could include anything from putting on socks or getting out of the car to walking or hiking. “All of those things you take for granted when the joints are working,” Polkowski said.

“We don’t make the judgment purely on how the joint looks on X-ray. It has to be a combination of joint damage and chronic pain that really limits the patient from doing the things that they need to be doing.”

However, certain underlying medical conditions can impact whether surgery is the right path for a patient. “If someone has too many risk factors that would increase the risk of having a bad outcome,” Polkowski said, “in those cases, we don’t necessarily recommend a surgical intervention.” Smoking, morbid obesity and poor nutritional status are some examples that can impact healing or increase the risk of infection.

But in many cases, a patient can work with the health care provider to reach optimal health and become a candidate for surgery, Polkowski explained. For example, if someone has diabetes that is poorly controlled, surgery can be delayed until better control is achieved. Or someone who smokes can undergo a cessation program first. “We really try to emphasize for people to improve their medical status going into a surgery like a hip replacement,” Polkowski said.

Not every risk factor can be eliminated, but having a pre-existing condition, like chronic lung disease or congestive heart failure, doesn’t eliminate surgery as an option for a patient. Vanderbilt’s pre-operative anesthesia team helps to optimize health before major surgery in high-risk patients, Polkowski said. “There are some things that we can’t fix before surgery,” he explained. “But we don’t want to deny the opportunity for those patients to experience the benefits from a hip replacement if at all possible.”
