Hip replacement (hip replacement surgery) is an operation in which the natural joint is replaced with artificial implants. Usually the procedure lasts about 1–2 hours and recovery takes weeks, with a progressive rehabilitation program.

What is a hip replacement
Hip replacement surgery is a joint replacement procedure (arthroplasty). In most cases a total hip replacement is performed: the femoral “head” and the hip socket (acetabulum) where it articulates are replaced.
Less commonly, a partial replacement may be performed in selected cases (for example certain fractures or particular conditions).
When a hip replacement may be indicated
You may consider surgery when symptoms make normal activities difficult or unsafe. The most common signs are:
- Significant hip pain, even at rest or at night.
- Stiffness and loss of mobility (reduced range of motion).
- Difficulty walking, climbing stairs, getting dressed or performing household tasks.
- Progressive limitation despite conservative treatments.
The most common cause is hip osteoarthritis, but trauma and other conditions can also damage the joint and cause similar symptoms.
Usually, before surgery, strategies such as medication, physiotherapy, targeted exercise and, when needed, use of a cane or walking aid are tried.
Types of hip replacement
The specialist may offer you:
- Total hip replacement: complete replacement of the joint (the most common).
- Partial hip replacement: replacement of part of the joint (rarer and tied to specific indications).
The choice depends on the diagnosis, anatomy, age, activity level and bone quality.
How to prepare for the procedure
Before the procedure, the surgeon performs a consultation and preoperative assessments. Typically:
- Symptoms and hip mobility are analysed.
- The affected hip is compared with the contralateral one.
- You are asked which medications and supplements you take (essential information for safety and bleeding management).
Usually some tests are requested, such as:
- Blood tests.
- Hip X-rays.
- Urine tests.
Depending on the case other investigations may be indicated (for example CT or MRI, electrocardiogram).
How hip replacement surgery is performed
In general, the procedure follows these steps:
- Anesthesia: regional anesthesia (for example spinal) is often used, which blocks pain over a large area; in some cases it may be combined with sedation.
- Removal of damaged parts: cartilage and compromised bone portions are removed.
- Insertion of the implant: the prosthesis may be made of materials such as metal, plastic and/or ceramic.
- Closure of the surgical wound: with sutures or equivalent devices.
Duration is often between 1 and 2 hours, but can vary depending on complexity and technique.
Benefits and risks: what to expect
Hip replacement is generally a very effective procedure: most people report a significant reduction in pain and improvement in stiffness. With full recovery, autonomy and the ability to walk, climb stairs and perform daily activities usually increase.
As with any surgery, there are risks. Complications are not frequent, but may include:
- Deep vein thrombosis or pulmonary embolism.
- Fractures around the prosthesis.
- Infection.
- Mechanical problems with the implant (loosening or dislocation).
- Persistent joint stiffness.
Prevention of complications relies on adequate preparation, pain management and, above all, a well-structured rehabilitation program.
After the procedure: what happens
After the operation, the team checks that awakening from anesthesia is safe and that no immediate problems occur.
In many cases the hip replacement can be managed with same-day discharge or with one night of observation, depending on clinical conditions and pathway organization.
Often within the first 24 hours guided exercises and controlled mobilization begin. Physiotherapist and surgeon monitor:
- Strength and flexibility.
- Ability to get up and sit down safely.
- Walking with aids, if necessary.
Recovery times: how long it really takes
Recovery requires patience and gradual progress. Generally:
- The first weeks are dedicated to pain control, protected mobility and restoration of walking.
- Physiotherapy continues for several weeks or months, depending on goals and individual response.
- For many people it takes about 6–12 weeks to return to using the hip with few or no limitations, but times may vary.
Age can influence recovery, but does not determine outcome alone: rehabilitation quality, consistency and general health matter greatly.
What to avoid in the early stages
The care team will give you precise instructions. In general, early on you should avoid:
- Crossing legs or ankles.
- Driving until the surgeon gives approval.
- Pushing knees too far past the waist line.
- Twisting or making extreme hip movements.
These restrictions are not permanent: they are adjusted as you regain strength and control.
How long does a hip replacement last
Modern implants are designed to last a long time. Many people keep the prosthesis for many years, often for life. In a minority of cases a revision surgery may become necessary over time; the specialist will explain what to expect based on your profile.
When to contact your doctor immediately
Contact the surgeon or care team if after the procedure you notice:
- Persistent bleeding or discharge from the wound.
- Marked redness, worsening of the area or secretions.
- Pus or foul smell from the wound.
- Intense uncontrollable pain.
- Significant swelling.
Do not wait: early intervention is the safest choice.
A tailored pathway
Facing a procedure can be anxiety-inducing, and that is normal. The important thing is not to stay alone with doubts and fears: an accurate assessment and a well-built rehabilitation program make the difference.
