Hip replacement surgery (either total or partial), refers to the surgical procedure in which the damaged hip is replaced with a prosthetic implant. It is typically performed when the hip is severely damaged either by an injury (e.g. car accident) or degenerative conditions such as osteoarthritis.Enquire Now
The common approaches to a hip replacement are the posterior approach and lateral Hardinge approach. In the last decade, direct anterior approach, a muscle sparing approach, has become increasingly popular.
Each approach has its benefits. Benefits of the direct anterior approach include faster recovery, and reduced risks of dislocation. However it does have a slightly increased rate of fracture and lateral thigh numbness.
Consult your doctor and have a good discussion regarding the approaches to a total hip replacement.
The benefits of hip replacement is reliable pain relief, and restoration of leg length. With less pain, patients may be able to return to the activities that they enjoy.
If you have decided to have a hip replacement surgery, you may undergo a series of tests to assess whether you have any other medical conditions that need to be treated beforehand. Other things to expect are:
The patient is first given anesthesia (either general or spinal). After the anesthesia has taken effect, incisions are made at the hip area and the damaged cartilage and bone are removed. They will then be replaced by prosthetic implants. A hip replacement surgery will go through the following steps:
You can also refer to the video above for a more detailed overview of the surgery.
You should expect the recovery period to span several weeks. That’s why many patients start physical therapy the day after surgery, or in the same afternoon if surgery was done in the morning. This usually takes the form of doing simple exercises while sitting on a chair. A physiotherapist will also help you get used to using supporting devices such as a walker or crutches.
As with any joint replacement surgery, physical therapy is highly recommended as it helps with the recovery process.
After a hip replacement surgery, your movements may be limited for a while. Reaching for high objects, bending down, and twisting are just a few of the things that you may have difficulty doing in the first few weeks following surgery. However, with consistent physical therapy, your muscles will strengthen and mobility will be restored.
You may also work with an occupational therapist so that they can advise you on how to go about doing your daily activities while minimising aggravation to the hip. This includes learning specific body posturing techniques, how to use the bathroom, and reaching for objects.
While the success rate for hip replacement surgery is high, you should still follow up with an orthopaedic clinic regularly so that your progress can be monitored and any complications can be dealt with swiftly.
Total hip replacement is generally a safe procedure. The risk of major complication after total hip replacement is <1%. However, chronic illnesses may increase the potential for complications. Although uncommon, when these complications occur they can prolong or limit full recovery. Common complications of hip replacement surgery include:
Your surgeon will discuss the risks with you in detail and will go over the necessary precautions that they will take to minimise the chances of complications occurring.
