Assisted Total
Hip Replacement

This type of replacement uses robotic-arm assisted technology for greater accuracy. Use of this technology has been shown to result in shorter hospital stays, smoother recovery and increased satisfaction.


Why use the Robotic Arm assisted Total Hip Replacement?
Robotic Arm Assisted surgery for a total hip replacement has been shown to be more accurate and to offer a greater improvement in patient function when compared to manual surgery. The precise and accurate placement of Hip implant may well be the difference between a good and an excellent or a so called ‘forgotten’ hip.


What does a Robotic arm assisted Total Hip Replacement involve?

Before surgery: 

In the weeks before your hip operation, a 3D CT scan of your hip is undertaken, which is then processed by the Robot. Your surgeon, with the assistance of the Robotic Arm Technology, plans the surgical procedure within a fraction of a millimetre.

During surgery: 

Your consultant is always in control during the operation. However, the Robotic arm assisted technology allows the consultant to perform the joint replacement with pinpoint accuracy, tailored to your anatomy, hip size and alignment. The robot does NOT perform the surgery, but helps the Consultant using the technology to place the surgical tools in the correct position to achieve this accuracy. 

The Procedure:

The procedure begins with the surgeon making an incision over the side or front of the hip. Using Robotic arm assisted technology, damaged and diseased cartilage and bone is excised after taking points around the hip to ensure accurate alignment and placement of the prosthesis. 

After appropriate trial, components are inserted. With a Robotic arm assisted hip replacement, your surgeon can be confident of precise placement and alignment of the component. This in turn significantly improves the chances of equal leg length and stability. The procedure takes approximately 60-90 minutes to complete.

Who needs a Total Hip Replacement?

The decision to undergo a Total Hip Replacement is a joint one between you, your family, GP and the Orthopaedic Surgeon. Those who benefit from Hip Replacement will have one or more of the symptoms:

  • Hip Pain that limits everyday activities like walking with significantly reduced walking distance
  • Pain at rest that affects sleep
  • Severe stiffness affecting mobility
  • Inadequate pain relief with NSAIDs or painkillers, Physiotherapy or walking aids

The indication for surgery are pain due to wear and tear Arthritis (Osteoarthritis), Inflammatory arthritis (Rheumatoid arthritis), Loss of blood supply to the ball part of the hip (Osteonecrosis), Arthritis following significant trauma to the hip (Posttraumatic Arthritis) or childhood hip conditions.

If you are a good candidate for traditional Hip replacement surgery, then you are a good candidate for robotic Hip replacement.

Recovery from Robotic-arm Assisted Total Hip Replacement

After the procedure, you will be taken to a recovery room for a few hours, before being moved to a hospital room where you will stay for one to two days. You will be given painkillers such as opioids or non-steroidal anti-inflammatory drugs (NSAIDs). You will be encouraged to start moving as quickly as possible following surgery, to reduce the risks of blood clots. 

Following the surgery, your Surgeon and Physiotherapist will visit you regularly. You will require a pair of crutches or some walking aid for a few weeks following surgery and you will be given a physical exercise programme to gradually build strength in your joint and muscles, while increasing the walking distance gradually.

Recovery is a fine balance between rest, following the recommended instructions/precautions reduce the risk of hip dislocation and staying active with increasing walks and exercise. Your surgeon and a trained physiotherapist will guide you through your recovery. It is common to require simple painkillers and NSAIDs during the early part of recovery.

Successful outcome

Hip Replacements are very successful operations with most patients experiencing dramatic pan relief and significant improvement in their ability to perform routine daily activities including walking. Since hip replacement is a technical procedure, it is important to choose an experienced surgeon with high surgical volume to ensure an excellent outcome. 

The activities one may be able to do after a successful Hip Replacement would include unlimited walking, swimming, hiking, biking, dancing, Golf, and light Badminton or Tennis. Most surgeons will advise against high impact activities.  It is therefore important to have realistic expectations about the outcome following a hip replacement.


Hip replacement is a very successful operation. However, like any other procedures, there are risks associated with a Hip Replacement that you must be aware of and accept prior to undergoing the procedure. The risks include Infection, Clots (Deep Vein Thrombosis), Embolus, Dislocation, Limb Length inequality, Persistent pain, incomplete relief of symptoms following surgery, Vessel or Nerve damage, Fracture, Re-operation/revision, medical, anaesthetic and mortality risks. As a surgical team, we make every effort to minimise these risks. This will include giving antibiotics before and after surgery, Injection/Tablet and use of surgical stockings to reduce the risk of clots and thorough pre and post-operative assessment and care.
