Hip Osteoarthritis: Symptoms, Non-Surgical Options and When Hip Replacement Becomes the Right Choice

Hip osteoarthritis rarely announces itself. For most people it begins as a stiffness in the groin on getting out of a chair, or a dull ache after a long walk that is easy to blame on age, shoes or a bad night’s sleep. By the time someone books an appointment, the joint has often been changing for years. Understanding what is happening inside the hip, what can be done short of surgery, and how the decision to replace the joint is actually made helps patients take control of a condition that otherwise tends to dictate its own terms.

What osteoarthritis does to the hip

The hip is a ball-and-socket joint. The head of the thigh bone sits inside a cup in the pelvis, and both surfaces are lined with articular cartilage, a smooth tissue that lets the bones glide with almost no friction. In osteoarthritis that cartilage thins and roughens. The underlying bone responds by thickening and growing small spurs at the edges of the joint, the lining of the joint becomes inflamed, and the space between the ball and socket narrows until, in advanced disease, bone rubs on bone.

It is a slow process, and it is not simply wear and tear. Genetics, previous hip injury, developmental problems such as hip dysplasia, obesity and occupations involving heavy lifting all raise the risk. Age is the strongest factor: a large population study estimated that about one in four people will develop symptomatic hip osteoarthritis in their lifetime, and the likelihood climbs steadily after 60.1

Symptoms to take seriously

Hip arthritis pain is usually felt in the groin or the front of the thigh, and it can travel down towards the knee. That referral pattern surprises people, and a surprising number of hip problems are first investigated as knee problems. Pain in the buttock or the outer hip is more often a sign of the lower back or the tendons around the hip, though the conditions can coexist.

The other hallmark is stiffness. Early on it appears after rest and eases within half an hour of moving. Later, the range of motion itself shrinks: putting on socks, cutting toenails and getting in and out of a car become awkward, and the leg may seem to have turned slightly outward. Many patients notice a limp before they notice pain, and night pain that wakes them is a sign of more advanced disease.

A doctor will confirm the diagnosis by examining the hip’s range of movement and ordering an X-ray, which shows the narrowed joint space and bone spurs. An MRI is not usually needed for osteoarthritis but may be ordered if a labral tear or another cause is suspected.

Non-surgical treatment comes first

Every major guideline agrees that treatment starts without a scalpel, and for many people it stays that way for years.2,3 The most effective measures are also the least glamorous.

Exercise and physiotherapy. Strengthening the muscles around the hip, particularly the gluteals, takes load off the joint and improves stability. Land-based exercise programmes reduce pain and improve function in hip osteoarthritis, and the benefit is comparable to that of painkillers without the side effects.3 Swimming, cycling and walking on flat ground are usually well tolerated; running and deep squatting are not.

Weight management. Each kilogram of body weight is multiplied several times over as it passes through the hip during walking. Even modest weight loss reduces symptoms and slows progression in people who are overweight.

Medication. Paracetamol has weaker evidence than most people assume. Topical anti-inflammatory gels are less useful for the hip than the knee because the joint is so deep. Oral anti-inflammatory drugs such as ibuprofen or naproxen work well for flares but are not intended for continuous long-term use because of stomach, kidney and cardiovascular risks.

Injections. A corticosteroid injection into the hip joint, usually performed under ultrasound or X-ray guidance, can give several weeks to a few months of relief and is often used to bridge a difficult period or confirm that the hip is indeed the source of pain. Hyaluronic acid and platelet-rich plasma injections are offered by some clinics; the evidence for them in the hip is weaker than in the knee, and guidelines generally do not recommend them routinely.2

Walking aids and daily adjustments. A walking stick held in the opposite hand reduces the force through the arthritic hip by a substantial margin. Raised chairs, long-handled shoe horns and avoiding low sofas all make daily life easier without changing the joint at all.

When hip replacement becomes the right choice

There is no X-ray score that sends a patient to theatre. Surgeons make the decision together with the patient, and it usually rests on three things: the amount of pain, the limitation of daily activities, and whether non-surgical treatment has stopped helping.3 Pain that wakes the patient at night, the need for daily painkillers, inability to walk more than a short distance and difficulty with basic self-care are the common tipping points. Age is far less important than it once was; the deciding question is how much life the arthritis is taking away.

Total hip replacement involves removing the damaged ball and socket and replacing them with a metal, ceramic or polyethylene implant. It is one of the most successful operations in modern medicine, so much so that The Lancet once described it as the operation of the century.4 Around nine in ten patients report substantial pain relief and improved function, and registry data show that modern implants have a high probability of lasting 20 years or more.5

The operation itself has changed considerably. Anterior and other muscle-sparing approaches, spinal rather than general anaesthesia, and enhanced recovery protocols mean many patients now walk on the day of surgery and go home within one to three days. Anyone weighing up the decision should ask their surgeon what hip replacement surgery looks like in their practice, including the surgical approach used, expected hospital stay, and how rehabilitation is organised, because those details shape the recovery as much as the implant does.

Surgery is not without risk. Infection, blood clots, dislocation and a difference in leg length are the main concerns, and they are discussed openly during consent. Full recovery takes three to six months, with most people back to driving in about six weeks. For patients whose hip has become the limiting factor in their life, that timeline is usually a small price.

Questions worth asking your doctor

Before deciding either way, patients get better outcomes when they arrive with questions. Is the pain definitely coming from the hip? Which non-surgical options have not yet been tried properly? What would waiting six months cost, and what would it gain? If surgery is recommended, why now, which approach, and what will the first two weeks at home actually look like? A good orthopaedic surgeon welcomes those questions, because a patient who understands the plan recovers faster and worries less.

Hip osteoarthritis is progressive, but it is not an emergency. There is time to strengthen, to lose weight, to try injections and to see how far conservative care can go. When it stops being enough, replacement is a well-understood, highly reliable next step rather than a last resort.
