What is hip replacement surgery?
Treatments for Arthritis
Unfortunately for many types of arthritis, including the most common types osteoarthritis and rheumatoid arthritis, there is no known cure. However, if you are diagnosed with hip arthritis, there are a number of treatment options depending on its severity, impact and type.
Arthritis differs from person to person but a lot can be done to enable you maintain a normal active life. Depending on your circumstances, the right treatment options may help relieve the symptoms of your arthritis or help minimise its progression. It is common to be prescribed or recommended to follow more than one option.
Drug therapies may be suitable to treat the symptoms of your arthritis such as pain (analgesics or painkillers), to suppress inflammation (anti-inflammatory drugs) or to inhibit some forms of inflammatory arthritis (disease-modifying anti-rheumatic drugs).
Physical therapies may include physiotherapy or light-exercise options such as hydrotherapy to restore or maintain function. Occupational therapy may help you to work with your arthritis and continue to achieve the activities that you need or want to maintain.
You may also be able to discuss lifestyle options including appropriate levels of activity including leisure and work activities, weight loss or even types of food that may trigger increased symptoms or arthritis.
If your arthritis becomes severe enough that despite these treatments it becomes too difficult to get on with everyday life or your pain is no longer sufficiently managed, surgery may be recommended.
What Is A Joint Replacement?
Joint replacement is the term used for surgically removing diseased or worn out bearing material in the body known as cartilage. The purpose of a joint replacement aims to remove the pain and allow a patient to return to their normal active function.
The bearing surface is replaced with a combination of metal, ceramic and/or plastic components. These components form an implant that work with the natural tissue around the joint to hold it together.
An implant is placed within the joint to provide an articulating interface for two bones that rub together, when the two bones rub together this is where a patient will start to feel in pain this can commonly be known as ‘bone on bone’. Over time the pain will worsen which will eventually have an impact on the patients’ health; they will find that everyday tasks such as climbing the stairs will become a painful experience.
Types of Hip Replacement Surgery
A total hip replacement (THR) is where both sides of your hip joint are replaced. Your hip surgeon removes damaged cartilage from the hip socket and replaces it with a new bearing surface. Your surgeon then removes the top portion of the thighbone and replaces it with an artificial hip usually made of a metal stem that is inserted into the cavity in the thighbone and has a peg on which a ball-shaped bearing is placed to articulate with the new socket. All components are made with particular metal alloys, ceramics or high-grade plastics that are proven to work in the human body.
An alternative to standard total hip replacement is hip resurfacing. This operation also replaces both sides of your hip joint; however, much like a knee replacement, only the worn cartilage is removed from both sides of the hip. Instead of removing the top portion of the thighbone and replacing it with a stem, this type of hip replacement uses the existing top (neck) of the healthy thighbone. Although this type of hip surgery removes less bone and does not require a stem to replace the top of the thighbone, it uses a larger bearing (closer to the size of your natural hip bearing) and requires a similar size of incision to a total hip replacement. Hip resurfacing delays and may avoid the need for total hip replacement.
Your hip specialist will help you to decide on which type of knee replacement surgery is right for you.
Implants: What Are They?
The main job of an implant is to provide an articulating surface. They are designed to work with the natural tissue, reproduce a motion that feels normal to the patient, and last for as long as possible. More innovative designs may enable patients to return to a normal level of pain-free activity without their hip joint wearing out too soon.
Implants: What Are They Made From?
Implants are usually two or more components which work together to make an implant. The components are made of implantable grade metal alloys, ceramics or high-density polyethylene.
All materials used to make up a device have been tried and tested, which have been proven to work well in the human body.
