What is hip replacement for hip dysplasia (DDH) and how does it work?
Hip replacement for hip dysplasia (DDH) is a total hip replacement in an adult whose hip socket (acetabulum) never developed normally. In developmental dysplasia of the hip the socket is shallow, tilted or too small, so the ball of the thigh bone (femoral head) is poorly covered. The joint carries load on a small area of cartilage and wears out early, often in a person in their thirties, forties or fifties. When pain, stiffness and a limp can no longer be controlled by other treatment, the worn surfaces are replaced with a metal, ceramic and plastic implant.
The operation follows the same principle as a standard replacement but is technically harder, because the socket, thigh bone and the muscles around the hip are shaped differently. This guide explains why dysplastic hips need special planning, how the surgeon rebuilds the socket, what the evidence says, who is suited, what hip replacement for hip dysplasia (DDH) costs in Turkey compared with the UK, US and Germany, and how to check a hospital. For related surgery see our orthopedics treatments in Turkey.
Why is a dysplastic hip harder to replace than a standard hip?
A normal replacement fits a cup into a deep, well-formed socket. In dysplasia the socket is shallow and may lie higher than usual, the bone may be thin or deficient at the upper edge, the femoral neck is often short and angled, and the thigh bone canal can be narrow and twisted. In severe cases the head has slipped completely out of the socket and the muscles and nerves have adapted to a shortened leg. The surgeon must place the cup in the true socket position, find enough bone to hold it, choose small or custom-sized components and avoid stretching the sciatic nerve when the leg is lengthened.
Dysplasia is graded by the Crowe classification from I (mild subluxation) to IV (complete dislocation). The higher the grade, the more complex the surgery, which is why planning on high-quality X-rays and often CT matters.
How is the socket rebuilt? Techniques used in hip dysplasia replacement
The technique depends on the grade. In mild cases a standard cementless cup, sometimes a slightly smaller one, is placed in the shallow socket and, if the roof lacks bone, supported by a bone graft taken from the patient's own femoral head. In moderate cases the cup is placed at the true socket level with extra fixation screws. In severe dislocation the surgeon may shorten the thigh bone with a subtrochanteric osteotomy, a cut just below the hip, so that the leg can be brought down without stretching the nerves; the bone is fixed with the stem or a plate.
Ask the surgeon to show you the plan on your own X-rays.
Does hip replacement for hip dysplasia work? What the evidence says
Yes, for most patients it relieves pain and restores walking. Studies of total hip replacement in dysplasia report good function and good implant survival in mild and moderate cases, although survival is generally somewhat lower than in osteoarthritis of normal hips, and complications such as nerve problems, leg-length difference and loosening are more common as the grade rises. The evidence is weaker for the most severe, completely dislocated hips and for very young patients, who may need more than one operation over their lifetime.
Outcome also depends on experience: a surgeon who treats dysplastic hips often plans these cases more reliably. A trustworthy hospital explains the grade of your hip, the specific risks that apply and does not promise a normal hip.
Hip replacement for hip dysplasia (DDH) cost in Turkey compared with the UK, US and Germany
The figures below are approximate ranges for one hip, not hospital quotes. The price is usually higher than for a standard replacement because of the extra surgical time, bone graft, special implants and often a longer stay. Each hospital confirms its price in a written quote.
| Country | Approximate cost range |
|---|---|
| Turkey | €7,000 – €20,000 |
| United Kingdom | €14,000 – €32,000 |
| United States | €28,000 – €70,000 |
| Germany | €14,000 – €32,000 |
What changes the price: the Crowe grade, whether a femoral shortening osteotomy or bone graft is needed, modular or custom implants, the bearing material, one hip or both, hospital nights and physiotherapy. A package normally includes scans and tests, the operation and anaesthetist, hospital nights, the implant, medication, early physiotherapy and transfers. Ask for the implant brand and for the plan in writing, since a complex case should not be quoted without X-rays.
Hip replacement, hip preservation or arthroscopy: how do the options compare?
The right treatment depends on how much cartilage is left. Younger patients with a dysplastic hip but little arthritis may be offered an operation that keeps the joint, while hips with advanced wear usually need replacement.
| Option | Suited to | Typical limits |
|---|---|---|
| Total hip replacement | Advanced wear, daily pain, limp | Implant wears over time; complex in high dislocation |
| Periacetabular osteotomy (PAO) | Young patients with good cartilage and a shallow socket | Long recovery; not suitable once arthritis is advanced |
| Hip arthroscopy | Labral tears and mechanical symptoms in mild dysplasia | Does not correct the shallow socket; unpredictable in dysplasia |
For a general explanation of the operation see total hip replacement. Some people with severe leg-length difference or angular deformity also need bone deformity correction, which a surgeon will discuss with you.
Who is a good candidate for hip replacement for hip dysplasia (DDH), and who is not?
You may be suited if X-rays show advanced arthritis in a dysplastic hip, you have daily pain, a limp or night pain that has not improved with medication, injections and physiotherapy, and you are fit for anaesthesia. Many patients are younger than the usual age for a hip replacement, and the surgeon will talk about implant life and the likelihood of a later revision, see revision hip replacement.
It is less suited if you are still young with good cartilage, where preserving the hip may be preferable; if there is an active infection; or if poor health, uncontrolled diabetes, smoking or severe obesity make complications likely.
How is the operation done, step by step?
- Planning: standing pelvis X-rays, often a CT, to grade the hip and measure leg length and socket depth.
- Anaesthesia: spinal anaesthesia with sedation or general anaesthesia, plus a nerve block.
- Approach: a cut over the hip, usually from the side or the back, to expose the joint.
- Socket: the cup is placed in the true socket, supported by bone graft or screws if the roof is deficient.
- Thigh bone: the stem is fitted; in severe cases a shortening osteotomy is made and fixed.
- Checks: leg length, stability and nerve function are checked before closing.
The operation takes about two to three hours, longer if a shortening osteotomy is needed. Most people stand with help on the same or next day.
Recovery after hip replacement for hip dysplasia (DDH): what to expect week by week
| Period | What usually happens |
|---|---|
| Days 1–4 | Hospital stay; first steps with a frame or crutches; blood-clot prevention |
| Weeks 1–6 | Walking aids; limited weight on the operated leg if a bone graft or osteotomy was used; wound check |
| Weeks 6–12 | Gradual full weight as X-rays show bone healing; strengthening; return to desk work |
| Months 3–6 | Walking without aids; low-impact exercise |
| Months 6–12 | Final improvement; swelling and any limp usually settle |
Most patients stay in Turkey about seven to ten days. If a graft or osteotomy was done, you may be told to limit weight bearing for several weeks, so do not plan a long trip before the surgeon allows it. A physiotherapist at home should follow the surgeon's plan. Ask about clot prevention for the flight.
Before and after: what realistic results look like
An X-ray shows the change clearly: a shallow, uncovered head before; a cup in the socket and a stem in the thigh bone after. Leg length may be corrected, which can make walking more even, but it will not always be exactly equal. Most people have less pain, a smoother gait and easier stairs and sitting. Expect a scar of about 10 to 20 cm. High-impact sport and heavy labour are generally discouraged.
What are the risks and complications of hip replacement in dysplasia?
The NHS lists infection, blood clots, dislocation, loosening and wear, leg-length difference and nerve injury as risks of hip replacement. In dysplasia some are more likely: sciatic or femoral nerve stretch when the leg is lengthened, bone healing problems if an osteotomy is made, fracture while fitting the stem in a narrow canal and a higher chance of later revision. Surgeons lower risk with careful planning, limiting lengthening, early movement, antibiotics and clot prevention. Ask the surgeon how often they treat Crowe type III and IV hips and what happens if a complication appears after you return home.
How to choose a surgeon and hospital, and red flags
Check that the surgeon is an orthopaedic specialist with regular experience of complex or dysplastic hips, that the hospital has an anaesthetist, intensive-care cover, nerve monitoring or experience in leg-length control and physiotherapy, and that you receive a written plan, the implant name and the price before a deposit. Red flags include a quote without CT or X-rays, no mention of your Crowe grade, an unnamed implant, promises of a normal hip and pressure to book quickly.

Frequently asked questions
It is a total hip replacement for an adult whose hip socket developed too shallow, so the joint wore out early. The surgeon rebuilds the socket, sometimes with bone graft, and fits a new ball and socket; in severe cases the thigh bone is shortened.
Yes, most patients get good pain relief and easier walking. Implant survival is somewhat lower and complications are more likely than in a normal hip, especially in severe dislocation, so ask about your grade and the surgeon's experience.
Approximate ranges are €7,000 to €20,000 in Turkey and about €14,000 to €32,000 in the UK. The price depends on the Crowe grade, graft or osteotomy, implant type and hospital stay; the hospital confirms it in writing.
On X-ray a shallow, poorly covered joint becomes a cup in the true socket with a stem in the thigh bone. Leg length and gait often improve, and the scar is typically 10 to 20 cm.
Most people walk with aids for several weeks, return to desk work after six to twelve weeks and reach their final improvement at six to twelve months. A shortening osteotomy or graft may mean limited weight bearing for longer.
Pain is controlled with nerve blocks and medication, and the first days are uncomfortable but manageable. Pain usually reduces steadily over the first weeks, and the prescribed exercises help rather than harm the new joint. Tell the team if pain suddenly worsens.
Many last 15 years or more, but survival tends to be lower than in standard replacements and younger patients may need revision later. Your weight, activity, implant and the complexity of your hip all matter.
It is performed by orthopaedic specialists in licensed hospitals. Risks include nerve injury, dislocation, infection and clots, so check how often the surgeon treats dysplastic hips, which implant is planned and what aftercare is offered before you travel.
A periacetabular osteotomy suits young patients whose cartilage is still healthy, while a replacement suits hips with advanced wear and daily pain. A surgeon should explain which fits your X-rays, your age and your daily activity level.
Most patients stay about seven to ten days: three to five nights in hospital, then physiotherapy and a wound check before flying. Ask the surgeon about weight-bearing limits and clot prevention for the flight home.
