Hip replacement surgery is a method wherein a defective hip joint is removed and replaced with an artificial hip joint. This procedure is only opted for after all the other treatments have failed to yield the desired effects. Hip replacement surgery removes damaged or diseased parts of a hip joint and replaces them with new, man-made parts. The goals of this surgery are to:

Relieve pain

Help the hip joint work better

Improve walking and other movements.

Who Should Have Hip Replacement Surgery?

The most common reason for hip replacement is osteoarthritis in the hip joint. Your doctor might also suggest this surgery if you have:

Rheumatoid arthritis (a disease that causes joint pain, stiffness, and swelling)

Osteonecrosis (a disease that causes the bone in joints to die)

Injury of the hip joint

Bone tumors that break down the hip joint.

Your doctor will likely suggest other treatments first, including:

Walking aids, such as a cane

An exercise program

Physical therapy

Medications.

These treatments may decrease hip pain and improve function. Sometimes the pain remains and makes daily activities hard to do. In this case, your doctor may order an x ray to look at the damage to the joint. If the x ray shows damage and your hip joint hurts, you may need a hip replacement.

The Procedure-

Hip replacement surgery is a procedure that can either be performed by traditional means or a minimally invasive procedure. The primary difference between the two procedures is the size of the incision. The procedure begins with the doctor administering local anesthesia, though in certain cases, general anesthesia is also administered.

An incision is then made along the hip and the muscles that are connected to the thigh bone are shifted, so that the hip joint is exposed.

An equipment is then used to remove the ball socket of the joint by cutting the thighbone.

The artificial joint is then fixed to the thighbone and it is allowed to adhere properly.

Once the joint is fixed, the ball of the thighbone is then put in the hip socket.

The fluids from the incision area are then allowed to drain.

The hip muscles are then put in place and the incision is closed.

Post -surgery-

After the surgery, the recovery stage begins. The period of hospital stay post-surgery usually lasts for 4-6 days. A drainage tube is attached to the bladder to get rid of waste products from the body. Physical therapy begins immediately after the surgery and you will be able to walk after a few days with walking aids. The physical therapy continues for a few months after the surgery.

After care-

It is advised to avoid activities that involve twisting your leg for at least half a year. You should also avoid crossing the leg along the mid portion of your body. Your physiotherapist will provide you with exercises that aid to help you recover. Avoid climbing stairs and sit on chairs that have strong back support.

Know Everything About Hip Replacement Surgery

Mobility for a person is very important, and when you look through, the hip is a very important component to this. It connects the upper and lower parts of the body and helps in movement. It is a ball and socket joint, where the hip bone provides a socket, into which the upper part of the thighbone (femur) sits into, allowing for free movement.

Like any other human organ, the hip also is prone to damage. Be it natural ageing, infection, injury, or diseases, hip movement can be affected, leading to limited movement and increased pain and stiffness. For these people, being able to get back a hip which will allow them to be back on their feet is a boon for sure. It helps in relieving pain and improving mobility, almost giving people a second lease of life.

Reasons for hip replacement:

With natural ageing, the hip joint can lose its ability to move, due to normal wear and tear of the hip and thigh bones
Diseases of the hips (infectious or autoimmune) can also lead to hip replacement
Injury or trauma is another major cause that requires hip replacement
Joint problems, leading to repeated dislocations
Tumours of the relevant bones
Understanding the procedure in detail

The affected bones (whether diseases or worn out) are replaced with a prosthesis which is compatible with the normal body tissue.
While some materials fuse to the natural bone, others do not and are simply placed as a separate unit
This is a surgery which requires hospitalisation and stays for up to 5 days depending on patient s overall health condition
The entire procedure may take a couple of hours and is usually done under general anaesthesia
An incision is made through the side of the hip
Both the hip and the thigh joints are prepared, diseased tissue removed, re-shaped, etc. to make way for the prosthesis
The prosthesis is introduced through the same incision and positioned into place
As noted earlier, there are two types. The ones which fuse to the bone have pores in them into which normal bone eventually grows.
The other variety is the cemented version, and a glue is used to keep it in place
Most doctors now use a combination, that is cement a porous prosthesis, into which bone will grow, and the incisions are closed
The patient stays in the hospital for 1 to 4 days depending on overall health
Once discharged, infection and pain control are continued
Exercise and physiotherapy play a major role in restoring normal function
Weight management is also very important

Hip Replacement - Understanding The Procedure In Detail!

Hip arthroscopy is a minimally invasive surgical procedure in which doctors view the joint problem without making any cuts through the skin and other soft tissues. Hip Arthroscopy is performed to treat several hip problems.

In Hip Arthroscopy, the doctors insert an arthroscope (a small camera) into the hip joint. The pictures are displayed on a video monitor with the help of an arthroscope. The surgeons will use these images to guide the surgical instrument.

As the surgical instrument and arthroscope are very thin, the surgeons make a very small incision compared to the one that is done in open surgery. As a result, patients feel less pain and stiffness in joints. This type of surgery also takes less time to recover and one can return to their normal life within a short period of time.

Hip Anatomy:

The hip is a socket and ball joint. The socket is formed by a part of a large pelvis bone called acetabulum. The ball joint is on the upper end of the femur (thighbone). Articular cartilage is a slippery tissue that covers the surface of the socket and ball. It creates a frictionless and smooth surface that helps the bones to glide across each other easily. Strong fibrocartilage is ringed on the acetabulum called labrum. It creates a gasket around the socket.

The joint is surrounded by a ligament, which creates a capsule to hold the joint together. The inner surface of the capsule is lined by a membrane called synovium. It produces a synovial fluid that helps in lubricating the joints.

When to Recommend Hip Arthroscopy?

If a person is suffering from chronic pain and does not respond to any other nonsurgical treatment, including physical therapy and medication, doctors may recommend a person opt for hip arthroscopy.

Hip arthroscopy helps a person to get relief from many problems that cause painful symptoms including damaged articular cartilage, labrum, or other soft tissues. The damage can be the result of any form of injury. However, there are other orthopedic conditions that can also lead to damage. The orthopedic conditions include:

Femoroacetabular Impingement (FAI):

In this type of disorder, an extra bone is developed on the femoral head (cam impingement) or along the acetabulum (pincer impingement). The overgrowth of the bone is known as spurs that damage the soft tissues surrounding the hip joint. In most cases, the bone spurs develop in either part. However, there are cases in which the bone spurs develop in both femoral head and acetabulum.

Dysplasia:

In this condition, the hip socket is abnormally shallow. Due to this problem, more stress is put on the labrum in order to keep the femoral head within the socket. This may raise the condition of the labral tear.

Snapping Hip Syndrome:

In this condition, the tendon rubs across the hip joint repeatedly. This type of popping or snapping is generally harmless and can be repaired without any treatment. However, the tendon may be fully damaged due to continuous rubbing in some cases.

Other conditions where hip arthroscopy is recommended include synovitis, hip joint infection, and labral tear.

Arthroscopic Femoroacetabular Surgery:

If the diagnosis results show that damage is caused by femoroacetabular impingement and a patient is not getting relieved from pain by any nonsurgical method, doctors recommend going for Arthroscopic Femoroacetabular Surgery.

In this type of surgery, the doctor repair and clear out the damage of the articular cartilage and labrum. He may also trim the rim of the acetabulum bone and shave the bump of the femoral head.

Arthroscopic Labral Repair:

If patients are not getting relief from conservative treatment, doctors recommend Arthroscopic Labral Repair. In this type of surgery, surgeons cut out and remove the damaged or torn part of the labrum. He further repairs the torn part by sewing it.

Take Away:

Both treatment methods are minimal incision processes and require fewer hospital stays. However, it is always advisable to consult a doctor before opting for any treatment.

Total Hip Replacement is also known as Total Hip Arthroplasty, in which the damaged cartilage and bones in the hip area are removed and replaced with prosthetic components. On the other hand, Total Knee Replacement, also known as Total Knee Arthroplasty or resurfacing, involves replacing the bone surface of the knee area. 

Causes of Hip and Knee Pain 

Arthritis is the most common cause of chronic hip and knee pain or disability. Other causes include: 

  Avascular necrosis or Osteonecrosis is a condition where there is an inadequate supply of blood to the femoral head due to a hip injury. The inadequate supply of blood may cause the bone surface to collapse and this can result in arthritis. 

  Rheumatoid Arthritis is the most common inflammatory Arthritis. In this condition, the synovial membrane surrounding the joint begins to thicken and become inflamed. This results in cartilage loss, stiffness, and pain. 

  Osteoarthritis is the type of arthritis, usually related to old age but can occur among young people too. The cartilage cushioning the hip and knee bones becomes soft and gradually wears off. The bones eventually start rubbing against each other which causes stiffness and pain in the knee and hip area. 

  Post-Traumatic Arthritis can follow a severe hip and knee fracture or injury. 

  Some children with hip disease or problem, even after treatment, can develop into arthritis later. This may be caused by uneven or unusual growth of hip which affects the joint surfaces. 

Knee Replacement Procedure 

  Bone Preparation: The surface of impaired cartilage at the end of the tibia and femur are separated besides a small extent of the underlying bone. 

  Locating the Metal Implants: The removed bone and cartilage are substituted by metal implants creating the joint surface. These metal pieces may either be press-fit or cemented into the bone. 

  Resurfacing the Patella: The undersurface of the kneecap or Patella is cropped and reformed with a plastic button. This process is variable depending upon the condition. 

  Inserting a Spacer: To form a smooth gliding surface, a plastic spacer of medical-grade is positioned between the metal components. 

Hip Replacement Procedure 

  Metal stem replaces the damaged femoral head and positioned into the femur s hollow center. 

  On the upper portion of the stem, a ceramic or metal ball is planted. This ball acts as a substitute for the damaged/detached femoral head. 

  The damaged Acetabulum or cartilage surface of the socket is discarded and supplanted by a metal socket. Cement or screws are used to sustain the socket in place. 

  A spacer, either metallic, plastic or ceramic is placed between the socket and the new ball for a smooth gliding surface. 

Take Away 

Knee and Hip Replacement are taken as the last option for the patient. The surgery and its outcome vary depending upon various factors. One should consult the doctor before undergoing for the Hip and Knee Replacement Surgery.

Primary Knee & Hip Replacement - Know More About Them!

Damaged hips can cause great distress in carrying out daily activities, such as walking, getting dressed and many more. If you have damaged one or both of your hips, and it causes you great pain, you may require a hip replacement. It is a common form of surgery in which a damaged hip joint gets replaced with an artificial one. This is known as prosthesis.

Conditions which lead to hip replacement

Osteoporosis where the cartilage inside a hip joint gets worn out, and the bones rub with each other as a result
Rheumatoid arthritis, which is caused when the immune system attacks the hip joint lining by mistake
If the hip joint gets damaged severely during an accident or fall
The purpose of a replaced hip joint is to provide pain relief, improve the hip s function, improve your ability to carry out day-to-day activities and improve your overall quality of life.

Procedure
A hip replacement is usually carried out under general anesthesia. An incision is made in the hip by the surgeon and the damaged hip joint is removed through it. It is replaced with an artificial metal alloy or a ceramic joint. The surgery takes approximately 60 to 90 minutes for completion.

Recovery
After the surgery, a walking aid such as crutches is required for up to four to six weeks. You may enroll for an exercise program, which aims at regaining and improving the new hip joint functions. Regular activities can be restored within two to three months. A year is required for utilizing the new hip joint normally.

Risks of hip replacement
There may be several complications as a result of a hip replacement. They include:

Dislocation of the hips
Infection at the surgery wound
Injury to nerves and blood vessels
Difference between the lengths of two legs
Fractures
Alternative
Hip replacement surgery has an alternative type of surgery, which is called hip resurfacing. During this surgery, the damaged surfaces of the bones within the hip joint are removed and replaced with a metal surface. Less bone is removed in this surgery. However, the metal surface may cause complications and health hazards.

Hip replacement is being improved upon with the advent of technology. Stronger and newer materials are being developed for prosthetics, which will allow enhanced joint mobility and a longer wear. New cement-less implants are also being developed. Also surgery assisted by computer is being used for generating an image of the hip joint.

 Hip Replacement - An Overview!

Physiotherapy plays a pivotal role in helping a person recover after a hip replacement surgery. It brings back the old flexibility and prevents blood clots in the area where the procedure has taken place. After the surgery team gives its green signal, a physiotherapist starts working with a patient for a full recovery. 

Here is a list of some common exercises that a physiotherapist suggests after a hip replacement surgery:

Walking: It is important to use the crutches for a time period of 4-5 weeks post the procedure. Until the surgeon or the physiotherapist advises against using the crutches, it makes sense to use it while walking. It makes sense to retain the normal walking posture by using the crutches rather than limping without it. A physiotherapist reviews the pressure exerted by the arm while holding a crutch, before advising the patient to get rid of the crutches.
Increasing hip flexibility: This is a basic form of exercise where an individual lies on one side of the body with knees and hips bent. A pillow is placed in between the knees. While doing this, it should be ensured that both the feet is kept together and the back muscle is not twisted. The top knee should be slowly raised like an opening of the calm shell. This position should be maintained for 4-5 seconds.
Strengthening the hips: The body should rest on the stomach. The buttocks should be tightened and one leg should be slowly lifted. This position should be maintained for a stretch of 3-5 seconds. The same should be repeated for both the legs.
Strengthening the hip and the stomach muscle: The body should rest on the back with a leg bent. The stomach muscle should be tightened and the bent leg should be lifted carefully while ensuring that the bend does not supersede more than 90 degrees. While keeping the stomach muscle tight, the lifted leg should slowly come down to touch the surface. This act should be repeated for 5-6 times.
Strengthening the thigh muscle: While sitting in a steady chair, an elastic loop should be wrapped around the ankles. The elastic loop should be stretched with one leg while keeping the other foot firmly rooted to the ground. The lifted foot should slowly come down to the normal position. The same act should be repeated for 4-5 times.
Improving balance: An elastic loop should be tied to one leg of a table and the other end of the loop should be tied to one ankle. The table should be held on for maintaining balance. Maintaining an erect position, the tied up ankle should be stretched sideways. The position should be maintained for 3-5 seconds to return back to normal standing position.
