Weighing the benefits and risks of hip replacement surgery

People stretching in a yoga classIf you or someone close to you is facing the prospect of hip replacement surgery, it’s only natural to have questions, worries and doubts. Join us as we weigh up the benefits and risks of hip replacement surgery in one clear and helpful article.

What happens during hip replacement surgery?

Hip replacement surgery is done under anaesthetic. The type of anaesthetic you have depends on your needs and your anaesthetist’s recommendations. Once the patient is under anaesthetic, the surgeon makes a cut over the side of the hip, removing the upper part of the femur from the socket. This is then replaced with an artificial joint. The operation itself usually takes less than two hours.

Whether it’s a routine procedure, or an urgent hip replacement, the surgery is similar; replacing the problem hip with an artificial joint.

Benefits of hip replacement surgery

Improved mobility and long-lasting results are key advantages, but the main benefit is pain relief. An arthritic hip can affect all areas of your life. Easing the pain following successful surgery can provide immediate benefits and a better quality of life.

Hip replacement surgery boasts a high success rate. A massive 95% of patients1 report feeling very pleased with the outcome of their operation. Only 5% experience a complication of some sort, the severity of which affects the success of their surgery.

Benefits of total hip replacement

Total hip replacement patients can expect to enjoy improved strength and better coordination.

If you or someone close to you is showing signs of needing a hip replacement, get in touch with your GP.

Is hip replacement considered risky surgery?

With the benefits of hip replacement surgery covered, it’s now time to look at the risks. While hip replacement surgery is a major operation, it’s actually one of the most common orthopaedic procedures in the UK.

There were 76,337 hip replacement procedures in England between April 2019 to March 2020 (pre-COVID 19 pandemic)2, and that number is expected to grow year-on-year as records are updated.

Hip replacement surgery risks and complications

So, what are the risks? Despite being a common operation, there are still some risks to consider.

During the operation, nerve damage and excessive bleeding are potential risks that should be taken into account.

Although uncommon, in the initial period following surgery, dislocation of the new hip joint can occur. This usually requires further surgery. Deep Vein Thrombosis and blood clots are also a risk post-surgery. Blood-thinning medication and compression socks are provided during the recovery process. If a patient experiences hot, reddened or hardening areas of their leg, they should contact their doctor immediately.

Infection is also an unlikely, but potential risk. Hip replacement surgeries take place in ultra-clean operating theatres, but infections can and do occur. In the event of infection, most can be managed with antibiotics with the need for further surgery very rare.

Other long-term risks of hip replacement surgery are mobility limitations and a change in leg length (Leg Length Discrepancy). Mobility limitations affect almost all patients during the recovery process. Leg Length Discrepancy is another risk to consider, and often requires managing through use of in-soles.

General wear and tear is another long-term risk to consider. Following a successful recovery process however, patients should expect their new hip to last between 10-15 years. Some last much longer while others need medical intervention much sooner, but 10-15 years seems to be the life expectancy of a new hip.

Hip replacement risk factors

Following surgery, patients should also be aware of the risks involving fractures and nerve damage. Nerve injury is a potentially serious complication of hip replacement surgery. It occurs between 0.6 and 3.7% of patients and is therefore considered a rarity.

Risks of hip surgery for elderly patients

Elderly patients face the same risks as those previously mentioned, but naturally may take more time to recover. As hip replacement surgery is generally thought of as a safe procedure, age isn’t considered an obstacle.

What is the most frequent complication following a hip replacement?

While hip replacement surgery isn’t considered a risky procedure, as with any major operation, there are risks of complications. Among the most common for hip replacement patients are blood clots. These are often found in the legs (Deep Vein Thrombosis) or in the lungs (Pulmonary embolus).

These risks are reduced significantly using precautions both in theatre and post-surgery.

How to reduce the risks

There are several things patients can do to minimise the risks from complications. These include:

  • Maintaining a healthy weight – this reduces the strain on the new joint
  • Avoiding falls – falling in the weeks after surgery could damage the new hip, either causing a fracture or dislocation requiring further operations. Extra care should be taken to avoid falling
  • Keep moving – Patients are generally encouraged to be up and about as soon as possible after their operation. Walking aids, hospital staff and physiotherapists will all help in the recovery process. Many patients can expect to be able to kneel after a total hip replacement following the precautionary three month period.

Patients should seek the advice of their GP straight away in the event any issues arise.
