Hip replacement surgery how it is performed its benefits and risks

If you have a hip joint problem, whether due to arthritis or a fracture, modern surgical techniques can help you return to your normal life. Hip replacement surgery is one of the most effective procedures for relieving pain and restoring mobility. There are two main types of this surgery: total hip replacement and partial hip replacement, each with its specific uses and conditions.In Dalili Medical, the following lines will cover everything you need to know about hip joint treatment in a simple and easy way.

How long does a hip replacement surgery take?

A hip replacement surgery usually takes between 1.5 to 3 hours. The duration depends on the complexity of the case, the type of artificial joint being used, and the surgeon’s expertise.

Will the pain be continuous in the early stages after hip replacement?

There’s no need to worry about post-surgery pain because your doctor will prescribe suitable painkillers to help you manage it. You may need to take these medications for two to three days after the surgery, or longer if required by your doctor.

Will I be able to engage in marital relations after recovery?

Of course! After 6 to 8 weeks, you should be able to return to your normal life, including your marital relationship. However, it’s best to consult your doctor first to ensure your condition is stable. The good news is that you will feel a significant reduction in pain after the surgery compared to before.

When will I be able to drive?

You can start driving again approximately six weeks after surgery, but you should get your doctor’s approval before resuming.

What are the reasons for undergoing hip replacement surgery?

Osteoarthritis (Joint Degeneration)

This is one of the most common reasons for hip replacement. Osteoarthritis occurs when the cartilage between the bones wears down over time, causing the bones to rub against each other. As a result, patients experience severe hip pain and difficulty in movement. In some cases, walking or standing for long periods becomes extremely challenging.

Fractures

If a fracture occurs in the femoral head (the part connected to the hip joint) due to an accident or injury, it can sometimes be too complicated to heal properly. In such cases, hip replacement surgery is the best option to relieve pain and restore mobility.

Arthritis (e.g., Rheumatoid Arthritis)

Rheumatoid arthritis is a chronic inflammatory disease that affects the joints. Over time, this inflammation can cause severe joint damage, pain, and movement difficulties. In such cases, a hip replacement can be an effective solution.

Congenital Deformities

Some people are born with hip joint deformities, such as misaligned bones within the joint. These conditions can cause severe pain and restricted movement. Over time, hip replacement surgery may become necessary to reduce pain and improve mobility.

Chronic Swelling and Stiffness

Some individuals suffer from persistent swelling or stiffness in the hip joint due to chronic diseases like arthritis or past injuries. If other treatments such as medication and physical therapy fail to provide relief, surgery may be the best solution to alleviate pain and restore function.

Necessary Tests Before Hip Replacement Surgery

Before undergoing hip replacement surgery, several important medical tests and evaluations are required. These tests help the doctor assess your overall health and determine if you are a suitable candidate for the procedure. They also minimize potential complications and ensure a safe and successful surgery.

Comprehensive Medical Examination (Medical History)

The doctor will ask about your medical history, including any chronic conditions such as diabetes, high blood pressure, heart problems, or previous surgeries. Additionally, your general health, including weight, height, and physical activity level, will be evaluated.

Blood Tests

Complete Blood Count (CBC): This test checks hemoglobin levels to detect anemia and white blood cell count to identify possible infections or inflammations.
Liver and Kidney Function Tests: These tests ensure that the liver and kidneys are functioning properly, as they play a crucial role in processing medications after surgery.
Blood Sugar Test: If you have a history of diabetes, this test is important for managing blood sugar levels before and after surgery.
Blood Clotting Test: Tests like Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) help assess your blood’s ability to clot properly, reducing the risk of excessive bleeding during and after surgery.

Heart and Lung Tests

Electrocardiogram (ECG): This test evaluates heart activity to ensure it is functioning properly before surgery.
Stress Test or Echocardiogram: If you have a history of heart problems, your doctor may require additional tests, such as a stress test or cardiac ultrasound (echocardiography).
Chest X-ray: This helps assess the overall health of your lungs and heart, ensuring there are no underlying conditions that could interfere with anesthesia or surgery.

Imaging Tests

Hip X-ray: This is essential for the doctor to evaluate the condition of the damaged joint and determine the extent of cartilage wear and joint deterioration.
CT Scan or MRI: In some cases, if a more detailed assessment of tissues or joint damage is needed, the doctor may request CT scans or MRI.

Bone Density Test

In rare cases, if you are at risk for osteoporosis, the doctor may recommend a bone density test (Densitometry) to assess bone strength before surgery.

Vascular Examination (In Some Cases)

If you have circulatory problems, your doctor may request a vascular test to evaluate blood flow in the legs.

Leg Doppler Ultrasound: A test to measure blood flow in the arteries and veins.

Anesthesia Assessment

Since hip replacement surgery requires either general or regional anesthesia, the doctor will ensure that you have no health issues such as allergies to medications or breathing problems that could affect anesthesia. In some cases, additional tests may be needed to confirm your ability to tolerate anesthesia.

Psychological Evaluation (In Some Cases)

If the patient has other health conditions or suffers from anxiety or depression, the doctor may conduct a psychological evaluation to ensure they are mentally prepared for the surgery.

General Health Assessment

The doctor will ask about any medications you are taking, especially blood thinners like aspirin or warfarin, to determine if you need to stop them before surgery.

How Is Hip Replacement Surgery Performed?

Preparation for Surgery

Before the surgery, the doctor will conduct several tests to assess your overall health, which may include:

X-rays of the hip
Blood tests
Heart and lung function evaluation

Additionally, the doctor may ask you to stop certain medications, such as blood thinners, before the procedure. You will also be informed about the details of the surgery and the expected recovery time.

Anesthesia Administration

Hip replacement surgery requires either general anesthesia (where you are completely asleep) or regional anesthesia (where only the lower part of your body is numbed). The anesthesia will be administered under the supervision of anesthesiologists to ensure your comfort during the procedure.

Incision (Opening the Skin)

The surgeon will make an incision around the hip joint area. The incision is usually made on the side or front of the hip and is large enough to allow the surgeon to access the joint easily.

Removing the Damaged Joint

Once the surgeon reaches the joint, they will remove the damaged or fractured joint. This involves:

Removing the femoral head (the ball-shaped part of the hip joint).
Removing the damaged part of the pelvis that connects to the joint.
In some cases, removing additional bone if there are deformities or alignment issues.

Implanting the Artificial Joint

After removing the damaged parts, the surgeon will insert the artificial hip joint, which is usually made of strong metals or durable plastic. The new joint is secured in place using special cement or by allowing the bone to naturally fuse with the implant.

The Artificial Hip Joint

The artificial joint consists of two main parts:

A component attached to the femur (thigh bone).
A component attached to the pelvic bone.

Closing the Incision

After securing the new joint, the surgeon will close the incision using medical stitches, either internal or external, depending on the case.

Recovery and Movement

After the surgery, the recovery phase begins. In the first few days, you will need assistance with movement and sitting. Your doctor will guide you through a physical therapy program to help you regain movement in the new joint. This therapy includes exercises to increase flexibility and strengthen the muscles around the joint.

Recovery Duration

In the first 1-2 days after surgery, you will stay in the hospital under observation.
You will start standing and walking with the help of crutches or a walker.
After a few weeks, you will gradually regain normal walking.
Full recovery may take several months before returning to normal movement.

Potential Risks

Like any surgical procedure, hip replacement surgery carries some risks, including:

Infection in the incision or the new joint.
Blood clots, especially in the leg.
Joint instability if it does not settle properly.

Why Does Leg Swelling Occur After Hip Replacement Surgery?

Normal Post-Surgical Reaction

After any surgery, the body needs time to heal, which can cause swelling in the tissues surrounding the joint. Hip replacement surgery involves cutting through the skin and tissues, leading to fluid accumulation in the area.

Effects of Anesthesia and Medication

Medications used during and after surgery, such as anesthesia and painkillers, can affect blood circulation, sometimes leading to leg or foot swelling.

Limited Movement

After surgery, reduced movement due to pain or the new joint's instability can cause fluid buildup in the leg, leading to swelling, especially in the lower leg.

Use of Crutches or Walkers

In the first few days post-surgery, using crutches or a walker may put uneven pressure on the leg, potentially causing swelling.

Incision and Inflammation

Surgical incisions may cause localized inflammation. Swelling is a normal part of the healing process, but if it worsens or is accompanied by fever or severe pain, it may indicate an infection.

Prolonged Sitting or Standing

Sitting or standing for long periods after surgery can cause fluid retention in the leg, leading to swelling.

Blood Clots (Deep Vein Thrombosis - DVT)

One of the potential risks of any major surgery is the formation of blood clots in the leg. If blood circulation is restricted, it may lead to leg swelling. That’s why doctors prescribe blood-thinning medications and recommend regular movement to prevent clot formation.

Pressure on Blood Vessels

In some cases, changes in body posture after surgery or prolonged sitting can put pressure on blood vessels, reducing blood flow and leading to swelling.

How to Manage Swelling?

Leg Elevation

Try to elevate your leg on a pillow to help drain fluids and reduce swelling.

Simple Exercises

Performing light exercises (after consulting your doctor) can stimulate blood circulation and improve fluid movement in the body.

Cold Compresses

Applying cold packs can help reduce swelling and pain, especially in the first few days after surgery.

Compression Stockings

In some cases, compression stockings can improve blood circulation and help minimize post-surgical swelling.

Is Hip Replacement Surgery Dangerous?

Hip replacement surgery is a major procedure, but it is generally safe and effective. Thousands of patients undergo this surgery successfully every year. Like any surgery, there are some risks and possible complications, but they are rare if proper precautions are taken and the patient follows medical instructions.

Potential Risks of Hip Replacement Surgery

Infection

As with any surgery, there is a risk of infection, either in the incision wound or the new joint itself. However, doctors take strict precautions, including prescribing antibiotics before and after surgery to minimize infection risk.

Blood Clots

After surgery, there is a chance of developing blood clots (deep vein thrombosis - DVT) in the leg, especially if the patient does not start moving soon after surgery. These clots can travel through the bloodstream and cause complications in the lungs or heart. To prevent this, doctors usually prescribe blood thinners or recommend simple exercises to improve circulation.

Joint Dislocation or Misalignment

In rare cases, the new joint may dislocate or shift after surgery. If this happens, additional surgery may be needed, but the chances of this occurring are very low.

Joint Inflammation

Sometimes, the body may react to the materials of the artificial joint, leading to inflammation in the new joint. However, this is extremely rare.

Nerve or Blood Vessel Issues

In rare cases, surgery may cause nerve or blood vessel injury near the hip joint. However, this is uncommon and is usually avoided with precise surgical techniques.

Pain or Stiffness After Surgery

Some patients may experience pain or stiffness in the joint after surgery, but this usually improves with physical therapy and the right exercises.

Factors That Reduce Surgical Risks

Thorough Pre-Surgery Evaluation

Pre-operative medical tests, such as X-rays and blood tests, help assess the patient’s overall health and minimize risks during and after surgery.

Proper Anesthesia Selection

Doctors carefully evaluate each patient’s condition before surgery to determine the most suitable anesthesia type, reducing potential complications.

Post-Surgery Physical Therapy and Exercise

Engaging in physical therapy after surgery reduces swelling and stiffness, helping the patient regain mobility faster.

Following Medical Instructions

Patients must follow the doctor’s instructions after surgery, such as avoiding prolonged pressure on the new joint and gradually increasing movement to prevent complications.

Is the Surgery Risky for Everyone?

Patients with Chronic Diseases

People with conditions like heart disease or diabetes require close monitoring before and after surgery, as they are at a higher risk of complications.

Patients with Limited Mobility After Surgery

If a patient cannot move or walk in the early recovery period, they may have a higher risk of blood clots, infections, or inflammation.

Best Sleeping Positions After Hip Replacement Surgery

Proper sleeping positions after a hip replacement are essential to avoid pressure or unnecessary movement on the new joint, ensuring safe recovery.

Sleeping on Your Back (Best Position)

Why?

Sleeping on your back is the safest position after hip replacement, as it reduces pressure on the new joint.

How to Do It:

Place a small pillow under your knees to relieve pressure on the hip.
Put a pillow between your legs to prevent excessive hip movement.
Keep your legs straight and parallel, avoiding sharp bending or twisting of the hip.

Sleeping on Your Side (In Some Cases)

Why?

Some patients can sleep on their side after a certain period, but only with precautions.

How to Do It:

Sleep on the unaffected side and place a large pillow between your legs to maintain a safe distance between them and prevent hip rotation.
Avoid sleeping on the operated hip in the early recovery phase.

Using Supportive Pillows

Pillow Between the Legs:

If sleeping on your side, keep a pillow between your legs to prevent hip twisting.

Pillow Under the Knees:

If sleeping on your back, place a small pillow under your knees to reduce pressure on the joint.

Avoid Sleeping on Your Stomach

Why Not?

Sleeping on your stomach is uncomfortable and risky after hip surgery. It can put excessive pressure on the joint or cause unwanted movement.

Moving While Sleeping

Important:

If you need to change positions, move slowly and carefully.
In the first few days, ask for assistance if needed to avoid sudden movements.

Complete Rest in the First Few Weeks

In the first 3-4 weeks, avoid sudden or extreme movements that could impact the new joint. Maintain a stable and safe sleeping position.

Elevating the Leg (Optional)

If you have swelling in the leg after surgery, slightly elevating it while sleeping can help reduce swelling.
However, always consult your doctor on the best way to do this.

When Can You Start Walking After Hip Replacement Surgery?

In the First Few Days After Surgery

During the first 24 to 48 hours, you will rest in bed under medical supervision in the hospital.
On the first or second day, you will begin taking small steps using a walker or crutches, under the guidance of a doctor or physical therapist.
The main goal is to start moving gradually to avoid complications like blood clots.
Initially, you will walk for short periods with assistive devices to avoid excessive pressure on the new joint.

After the First Week

Around 1 to 2 weeks after surgery, you will be able to walk better, but for short durations.
You will still need a walker or crutches at first, but over time, you will gradually walk more naturally.
Your doctor and physical therapist will schedule important exercises to improve movement and strengthen muscles.

After 4 to 6 Weeks

With continuous physical therapy, you will start feeling more stable while walking.
You will gradually reduce the use of crutches or a walker.
Some patients begin walking independently as they gain more confidence and strength.

After 3 to 6 Months

With consistent rehabilitation, you will notice significant improvement in your hip movement.
Most people walk normally within 3 to 6 months after surgery.
However, it is important not to rush movement and to follow medical guidelines regarding weight-bearing on the new joint.

Tips for Walking After Surgery

Follow your doctor’s instructions: Avoid putting sudden weight on the new joint, especially during the first few weeks.
Use crutches or a walker properly: These tools will help support your weight and prevent excessive pressure on the joint.
Do simple exercises: Physical therapy is essential to improve flexibility and strengthen the muscles around the joint.
Rest and get good sleep: Proper rest and good nutrition will help speed up recovery.
