Hip surgery

Total hip replacement (THR) surgery


Swiss Medical Network clinics perform more than 1,700 total hip replacements every year. Our highly experienced surgical teams have access to state-of-the-art technology and offer the most innovative and safest surgical techniques to meet the specific needs of each patient.

What is a hip prosthesis?

An ‘artificial hip,’ known as a prosthesis, is used to replace a small part of the worn joint, using mechanical components that form a new surface, allowing the joint to move smoothly without pain. The prosthesis is made up of several component parts and various materials:

  • A titanium femoral stem
  • A ceramic or metal femoral head
  • A polyethylene or ceramic liner and acetabular cup 

Depending on your medical condition, bone quality, level of activity and various other factors, your surgeon will choose the prosthesis and surgical technique that are best for you.

Why have hip replacement surgery?

Hip replacement surgery is usually performed to treat coxarthrosis (osteoarthritis of the hip). Coxarthrosis may be caused by a number of factors, including injury, deformity or ageing. Depending on how advanced your condition is, we may be able to offer conservative treatment options. However, if there is too much wear and tear to the cartilage and bone forming the hip joint, an artificial hip prosthesis may need to be fitted to replace the damaged joint. 

Different shapes and materials are available, for example a ceramic head, polyethylene components and an anatomic, cementless stem. Your surgeon will ensure you receive the type of prosthesis that is safest for you and most appropriate for your needs, for example your level of activity and bone quality.

What are the benefits?

By treating coxarthrosis, the aim of hip replacement surgery is to:

  • Significantly reduce pain
  • Restore mobility 
  • Improve the quality of everyday life

Only your surgeon, a proficient medical professional, has the expertise and experience to offer you the best possible care for your condition.

Hospital stay and post-surgery rehabilitation care

We believe that following the instructions received before your procedure plays a key role in your care.

A pre-operative assessment will be carried out to determine whether you will have a regional or a general anaesthetic. The procedure takes an average of one to two hours. You will stay in hospital for between five and seven days, depending on how quickly you recover.

After surgery and supported by our specialist teams, you will be expected to quickly start your physiotherapy programme and gradually do more and more exercises. You will be able to get up and walk, initially using a walking aid, and then without any support.

It is very important that you follow the physiotherapy and rehabilitation programme closely to ensure your procedure is as successful as possible.

You can usually return to driving after a few weeks, depending on how quickly you recover and wich hip was replaced. You can also expect to return to sports after a few months, depending on the type of physical activity. However, we recommend that high-impact contact sports should still be avoided.

Dual mobility hip replacement

What is a dual mobility hip replacement? 

The concept of dual mobility is a major breakthrough within the field of total hip replacements that has occurred within the last decade. 

A total hip replacement involves replacing the joint surfaces of the hip, the femoral head and the surface that fits into the acetabular cavity within the pelvis. A conventional total hip replacement is made up of two parts: a femoral part, which replaces the femoral head, and a metal cup, which replaces the acetabular cavity. An insert is then fitted into this metal cup, making it possible to restore articular movement and the ranges of mobility, and relieve pain. 

The principle remains the same in the case of a dual mobility implant. However, the insert within the metal cup, which is usually fixed, is replaced with a mobile insert, which enables two areas of movement: a first area between the prosthetic head and the mobile insert and a second area between the insert and the metal cup. This helps to significantly increase the effective diameter of the prosthetic head.


Increasing the effective diameter of the prosthetic head helps to increase the ranges of mobility. Not only that, but the risk of dislocation is reduced with a larger prosthetic head diameter – the patient can cover a much greater distance before the risk of dislocation occurs compared with a conventional implant. 

Which patients is this suitable for?

Dual mobility hip replacements are used in both initial surgery and revision surgery.

Initial surgery 

It is recommended for patients with a risk of dislocation, including:
•    people aged seventy and over
•    people who have been fitted with a total hip replacement after fracturing the femoral neck
•    patients with inflammatory rheumatism 
•    patients with neuromuscular diseases, Parkinson’s disease or myopathies

Revision surgery

Dual mobility hip replacements are particularly recommended in the case of revision surgery for total hip replacements because the risk of dislocation is significantly higher in the case of a revision (between 5% and 10%). By using a dual mobility implant, the risk in the case of a revision is reduced to between 1% and 2%. 

Revision of a hip replacement 

Artificial hips have a limited lifespan and usually need to be revised in order to prevent complications arising. This is what is meant by prosthesis revision. 
However, the degree of precision of the insertion techniques used and increasing the quality of the materials used in the course of primary implants helps to increase the lifespan of the replacements and reduce the need for revision.

Rehabilitation at Clinique Valmont

Patients recovering from hip surgery require orthopaedic rehabilitation. Clinique Valmont offers a range of tailored rehabilitation programmes as well as first-class treatment in an idyllic setting with stunning views of Lake Geneva and the Alps.

Patients receive help and training in different daily activities (bathing, dressing, cooking, etc.) and motor rehabilitation (strength, mobility and sensitivity) as well as advice on posture.

The specialists at Clinique Valmont do everything possible to maximise the recovery potential of each patient and make them more self-sufficient and independent while minimising functional impairment. Clinique Valmont offers both inpatient and outpatient care depending on the circumstances of each patient.

Swiss Medical Network patients can enjoy exclusive benefits during their rehabilitation programme at Clinique Valmont.

The clinic has partnered with all supplementary health insurance providers.
