Signs that hip replacement may be necessary

You need hip replacement when the cartilage in your hip joint has worn down enough that bone rubs on bone, and pain or stiffness stops you from doing daily tasks — not when you have occasional hip pain. The clearest sign is pain that does not improve with rest, ice, anti-inflammatory medication, or physical therapy over several months. If you cannot walk without a cane or walker, cannot put on shoes or socks, or wake at night because of hip pain, those are the moments when orthopedic surgeons typically recommend surgery.

The decision is not automatic. Your doctor will take X-rays to see how much cartilage remains and check whether bone spurs or other damage is visible. They will also ask whether you have tried conservative treatments — physical therapy, weight management if relevant, injections, or activity changes — and how long you have been limited. A person with severe arthritis on an X-ray but no symptoms does not need surgery. A person with moderate arthritis who cannot walk without pain does.

Key Takeaways

  • Hip replacement becomes necessary when cartilage loss causes bone-on-bone contact and pain that does not respond to rest, medication, or physical therapy over months.
  • You should consider surgery when pain limits your ability to walk, climb stairs, or perform basic self-care tasks like dressing or bathing.
  • X-rays show the extent of cartilage loss and bone damage, but imaging alone does not determine whether you need surgery — your symptoms do.
  • Most people try physical therapy, weight management, and anti-inflammatory medication for at least three to six months before surgery is discussed.
  • Age is not a barrier; the decision depends on your pain level, activity goals, and how much conservative treatment has helped.

How to tell the difference between normal wear and joint damage

Hip pain after a long walk or a day of activity is normal. Hip pain that wakes you at night, pain that does not go away after a day of rest, or pain that gets worse over weeks and months suggests cartilage loss. You can also notice the difference in how your hip moves: normal hips let you bend forward to touch your toes or rotate your leg outward without sharp pain. If those movements cause a catching sensation, a sharp pinch, or pain that radiates down your thigh or into your groin, cartilage damage is likely.

Stiffness that improves after you move around for a few minutes is common in older joints. Stiffness that does not improve, or that gets worse as the day goes on, points to arthritis. Many people describe it as the hip feeling "locked" or "stuck" in certain positions. If you find yourself limping to protect the hip, or if you have started using a cane without being told to by a doctor, your body is telling you the joint is damaged enough to change how you move.

What happens during the evaluation with an orthopedic surgeon

Your primary care doctor can refer you to an orthopedic surgeon, or you can request a referral yourself. At the appointment, the surgeon will ask how long you have had pain, what makes it better or worse, and what activities you can no longer do. They will move your leg in different directions to test your range of motion and feel for grinding or catching. They will ask whether you have tried physical therapy, how many weeks or months you did it, and whether it helped.

X-rays are standard. The surgeon will show you the images and explain what they see: whether cartilage space is narrowed, whether bone spurs are present, and how much of the joint surface is still intact. They may also order an MRI if the X-rays are unclear or if they suspect other damage. The surgeon will then discuss whether surgery makes sense for you right now, or whether more conservative treatment is worth trying first. This conversation depends on your age, your overall health, how much pain you are in, and what you want to be able to do after recovery.

Pain that suggests you should see a doctor soon

Contact your doctor if hip pain is constant, even at rest or at night. Contact them if pain is getting worse week by week despite medication or rest. Contact them if you cannot bear weight on the leg, or if the pain is accompanied by swelling, warmth, or redness — those can signal infection rather than arthritis. If you fall and have severe hip pain afterward, see a doctor right away to rule out a fracture.

You do not need emergency care for chronic hip pain, but you should not wait months hoping it will resolve on its own if it is affecting your ability to walk or sleep. The longer you wait, the more you may change how you move to protect the painful hip, which can lead to problems in your knee, ankle, or lower back. Getting an evaluation while you still have some function makes the surgery less urgent and gives you time to prepare.

Why conservative treatment comes before surgery

Physical therapy, weight management, and anti-inflammatory medication are tried first because they work for many people and carry no surgical risk. A physical therapist can teach you exercises that strengthen the muscles around your hip, which takes pressure off the joint itself. They can also show you how to move in ways that do not aggravate the pain. If you are overweight, losing weight reduces the load on the joint and often reduces pain noticeably.

Injections of corticosteroid or hyaluronic acid into the joint can reduce inflammation and pain for weeks or months. Some people get relief that lasts long enough that they never need surgery. Others find that injections help temporarily but pain returns. Your surgeon will want to know what you have tried, how long you tried it, and what the result was. If you have done three to six months of physical therapy, lost weight if relevant, and taken anti-inflammatory medication without significant improvement, surgery becomes a more reasonable choice.

Age and activity level in the decision to have surgery

Surgeons no longer have a strict age cutoff for hip replacement. People in their 50s, 60s, 70s, and beyond have the surgery successfully. The real question is whether you are healthy enough for surgery and anesthesia, and whether you are willing to follow the recovery process. Your surgeon will review your medical history and may order blood work or an EKG to make sure surgery is safe for you.

Activity level matters more than age. If you want to walk, hike, travel, or play with grandchildren, and pain is stopping you from doing those things, surgery can restore that ability. If you are mostly sedentary and pain is not affecting your daily life, surgery may not be necessary. Modern hip replacements are designed to last 15 to 20 years or longer, so a person who has surgery at 60 may need a second surgery later in life — something to discuss with your surgeon.

What to expect after you decide to have surgery

Once you and your surgeon agree that replacement is the right choice, you will schedule the surgery and prepare. Your surgeon will give you a list of medications to stop before surgery, usually including blood thinners and some anti-inflammatories. You will meet with the anesthesiologist to discuss your medical history. You will likely do pre-surgery physical therapy to strengthen your muscles, which helps recovery go faster.

The surgery itself takes one to two hours. You will spend a night or two in the hospital, then go home or to a rehabilitation facility. Recovery takes weeks: you will use crutches or a walker at first, then gradually put more weight on the leg. Physical therapy continues at home and in an outpatient clinic. Most people can walk without information within four to six weeks and return to normal activities within three months. Pain relief is usually dramatic — most people say the surgery pain is worth it because the chronic pain is gone.

Frequently Asked Questions

Can I avoid hip replacement by losing weight or exercising more?

Weight loss and exercise help many people with mild to moderate arthritis, and they are worth trying for several months. If cartilage is severely worn, however, no amount of weight loss will restore it. Your surgeon can tell you from X-rays whether conservative treatment is likely to help or whether damage is too advanced.

What if I have pain in both hips?

Both hips can develop arthritis, and both may eventually need replacement. Surgeons usually operate on one hip first, let you recover and regain strength, then do the other hip months later. Some people choose to have both done at once if they are young and healthy enough, but recovery is more demanding.

Will I be able to do the activities I enjoy after hip replacement?

Most people return to walking, swimming, golf, gardening, and travel. High-impact activities like running or jumping are generally not recommended because they can wear out the replacement faster. Your surgeon will discuss which activities are safe for your new hip.

How do I know if my hip pain is arthritis or something else?

Only an X-ray can confirm arthritis. Hip pain can also come from muscle strain, bursitis, nerve problems, or problems in your lower back. Your doctor will examine you and may order imaging to find the real cause before recommending any treatment.

Is hip replacement surgery risky?

Hip replacement is one of the most common and successful orthopedic surgeries. Serious complications like blood clots or infection occur in fewer than 2 percent of cases. Your surgeon will discuss your individual risks based on your age and health before you decide to proceed.
