Hip Replacement Surgery

Hip replacement surgery is the replacement of a damaged hip joint with an artificial joint in order to reduce pain and improve movement. It is most often considered in advanced osteoarthritis, certain fractures, and pain severe enough to interfere substantially with daily life; however, the decision is not based on X-ray findings alone. Symptom severity and the degree of functional loss are equally important. ^[1][2][3]

What exactly is hip replacement surgery?

Hip replacement surgery is also known medically as total hip arthroplasty. In this procedure, the damaged bone and cartilage surfaces that form the hip joint are removed and replaced with prosthetic components made of metal, ceramic, and durable plastic. The goal is not only to relieve pain, but also to make core functions such as walking, sitting, climbing stairs, and sleeping more comfortable. The type of implant used may vary according to age, bone quality, activity level, and the surgeon’s assessment. ^[1][2][3]

This operation is usually considered when other treatments have not provided adequate relief. Medications, physical therapy, weight management, the use of a cane, or intra-articular treatments may help for a time; however, if pain has become persistent, daily function is clearly impaired, and quality of life has declined, joint replacement becomes a stronger option. Imaging alone does not determine the decision; the patient’s symptoms and goals are also central. ^[1][2][3]

Who may be a suitable candidate?

Hip replacement is performed most commonly for advanced osteoarthritis. It may also be needed in inflammatory joint diseases such as rheumatoid arthritis, fractures around the hip, avascular necrosis of the femoral head, and certain structural abnormalities. Important warning signs include pain at rest, night pain, a marked reduction in walking distance, and difficulty with simple activities such as putting on shoes or getting up from a chair. ^[1][2][3]

Not every case of hip pain means a hip replacement is necessary. In younger patients, in people whose pain fluctuates, or in those who may still benefit from non-surgical options, conservative treatment may be tried first. By contrast, if pain has led to reduced movement, muscle loss, impaired balance, and an increased risk of falls, a surgical evaluation should not be delayed. The final decision is based on the orthopaedic examination, imaging findings, and coexisting medical conditions. ^[2][3][4]

How is the preoperative evaluation performed?

Before surgery is planned, the team clarifies whether the source of pain truly arises from the hip joint. Problems in the lower back, knee, or surrounding soft tissues can sometimes mimic hip pain. Physical examination, X-rays, and additional tests when needed are used at this stage. Factors such as cardiovascular disease, diabetes, infection risk, smoking, kidney function, and blood-thinning medications are also important for surgical safety. ^[1][2][5]

Home preparation and the rehabilitation plan should also be discussed before surgery. Using a higher chair, removing loose or slippery rugs, preparing a walking aid, and arranging for someone to help during the first days may all make recovery easier. Surgery is not limited to the day of the procedure itself; preparation beforehand is just as valuable as the operation for a safe recovery. ^[3][4][5]

How is hip replacement surgery performed?

During the operation, the surgeon removes the damaged femoral head and the worn surfaces of the hip socket. A cup is then placed into the socket, and a prosthetic stem-and-head component is inserted into the thigh bone. Prosthetic components may be cemented or uncemented. The choice depends on bone quality, age, and the surgical plan. Although procedure time varies by centre and by case, it often takes approximately one to two hours. ^[1][2][3]

Although technical details differ from patient to patient, the core aim remains the same: to eliminate painful joint surfaces and restore a balanced, functional joint. Some centres now use smaller incisions, navigation systems, or robotic assistance; however, incision size alone is not the key factor. Appropriate patient selection, the right implant, and good rehabilitation matter more. ^[1][3][4]

What are the risks and possible complications?

Although hip replacement is successful in many people, it carries risks like any operation. These include infection, blood clots, bleeding, prosthetic dislocation, a perceived difference in leg length, nerve or vascular injury, and loosening of the implant over time. Some patients may also experience pain or stiffness that lasts longer than expected after surgery. For that reason, both potential benefits and risks should be discussed clearly before a decision is made. ^[1][2][3]

To reduce the risk of complications, infection control, blood clot prevention, early mobilization, and an appropriate exercise programme are critical. Active infections such as dental or skin infections should be treated before surgery, and smoking cessation and good diabetes control may also affect outcomes. Sudden leg swelling, shortness of breath, drainage from the wound, or fever after the operation require urgent evaluation. ^[3][4][5]

What is recovery and rehabilitation like?

Many people are helped out of bed shortly after surgery and begin walking exercises early. Early movement reduces the risk of blood clots and helps reactivate the muscles. The use of a walker or crutches is common in the first days. Pain may not disappear immediately, but in most patients there is noticeable functional improvement within weeks. Even so, the pace of recovery varies according to age, muscle strength, preoperative mobility, and accompanying medical conditions. ^[1][4][5]

The aim of rehabilitation is not just walking. It also includes regaining safe sitting and standing, climbing stairs, dressing, and balance. It is important to perform the exercises recommended by the orthopaedic and physical therapy team regularly, to prevent falls, and to avoid excessive twisting or bending movements in the early phase. Some restrictions differ depending on the surgical approach used, so the personalised instructions provided by your surgeon should take priority over generic internet advice. ^[3][4][5]

Quality of life after hip replacement and long-term expectations

A successful hip replacement can make it easier for a person to return to daily life by reducing pain. Many patients report that they walk, sleep, sit, and stand more comfortably. Even so, a prosthetic joint is not identical to a natural biological joint, and high-impact sports or activities that place excessive load on the joint may not always be appropriate. Which activities are safe to resume should be assessed according to the implant type and the patient’s clinical status. ^[1][3][4]

Long-term follow-up visits remain important. If pain recurs, if there is a marked change in walking, if infection is suspected around the prosthesis, or if a fall occurs, early evaluation is advisable. Hip replacement can be a highly effective procedure in the right patient, but the best results are achieved with realistic expectations, regular follow-up, and good rehabilitation. ^[2][4][5]

When should you see a doctor?

If your hip pain does not improve over weeks, wakes you at night, limits your walking capacity, or makes everyday tasks difficult, an orthopaedic evaluation is appropriate. After surgery, increasing redness, drainage from the incision, fever above 38°C, calf swelling, chest pain, or shortness of breath are not expected findings and require prompt medical assessment. ^[1][3][5]

The decision to undergo hip replacement does not need to be rushed, but it may also be unwise to postpone it unnecessarily when there is marked functional loss. A safer and more satisfactory path usually emerges when the individual assessment, expectations, risks, and postoperative lifestyle are discussed together. ^[2][3][4]
