🦴 Total Hip Replacement: A New Beginning for Pain-Free Movement

Hip arthritis can make even simple daily activities painful. When the joint becomes severely damaged, a Total Hip Replacement (THR) can restore mobility, reduce pain, and improve quality of life.

This short animation demonstrates the key steps of a modern hip replacement—from preparing the joint to implanting the artificial components and restoring smooth movement.

✅ Relieves pain
✅ Improves mobility
✅ Helps patients return to everyday activities

Remember, every patient is unique. The most appropriate treatment depends on your symptoms, examination, imaging findings, and overall health. Always discuss your options with your orthopaedic surgeon.

🦴 Hip Hemiarthroplasty – Restoring Mobility After a Hip Fracture

A hip hemiarthroplasty is one of the most common operations performed for displaced femoral neck fractures, especially in older adults.

Unlike a total hip replacement, this procedure replaces only the femoral head, while preserving the patient’s natural acetabulum.

✅ Helps patients return to mobility sooner
✅ Relieves pain caused by the fractured hip
✅ Commonly performed after a fall in elderly patients

🎥 This animation demonstrates the key surgical steps in a simplified educational format.

❓Quick Quiz: Which part of the hip is replaced during a hemiarthroplasty?

A️⃣ Acetabulum only
B️⃣ Femoral head only
C️⃣ Both the acetabulum and femoral head
D️⃣ Pelvis only

🚨 Why Doesn’t Every Hip Replacement Dislocate When You Cross Your Legs?

Modern total hip replacements (THR) are more stable than ever. In fact, many patients today have fewer movement restrictions than in the past.

However, hip dislocation can still occur, particularly in patients with certain risk factors such as:
🦴 A posterior surgical approach
🦴 Soft tissue weakness
🦴 Component malposition
🦴 Revision hip replacement
🦴 Early healing after surgery

🎥 This animation demonstrates one possible biomechanical mechanism of a posterior hip dislocation when hip flexion, adduction (crossing the legs), and internal rotation occur together.

⚠️ This does not mean every patient will dislocate by crossing their legs. Postoperative advice should always be individualized based on the surgical technique, implant, and your surgeon’s recommendations.

💬 Question for you:

Which factor do you think has the greatest influence on preventing a hip replacement dislocation?

A. Surgical approach
B. Implant positioning
C. Soft tissue repair and muscle strength
D. Patient movement and rehabilitation

👇 Comment A, B, C, or D below. I’ll reveal the answer and explain why in the comments later!

🚨 Can simply crossing your legs dislocate a hip replacement?

Not every patient will experience a hip dislocation—but in certain situations, the combination of hip flexion, crossing the legs (adduction), and internal rotation can increase the risk, especially during the early recovery period after a posterior total hip replacement.

🎥 This animation demonstrates how a prosthetic hip can dislocate when these movements occur together. It is intended to explain the biomechanics behind one possible mechanism of dislocation.

⚠️ Modern hip replacements are more stable than ever, and postoperative precautions are increasingly individualized. Your surgeon’s advice will depend on factors such as the surgical approach, implant design, soft tissue repair, and your personal risk profile.

🦴 Knowledge is power—and understanding your hip replacement helps you recover safely.

❓Quick Poll:
After your hip replacement, were you advised to avoid crossing your legs?

🔹 A. Yes
🔹 B. No
🔹 C. Only during the first few weeks
🔹 D. I haven’t had a hip replacement

🦴 Total Knee Replacement Quiz!

Which part of a knee replacement acts as the new smooth bearing surface between the metal implants?

B️⃣ Polyethylene insert
C️⃣ Femoral stem
D️⃣ Patella

🦴 Does your hip replacement sometimes make a squeaking sound?

Hearing a squeak after a total hip replacement can be surprising—but it doesn’t always mean something is wrong.

In some patients, especially those with ceramic-on-ceramic hip replacements, a squeaking sound can occur due to the way the smooth bearing surfaces move and vibrate against each other.

✅ An occasional, painless squeak is often not a sign of implant failure.

⚠️ However, if the squeaking is:
• Painful
• Happens frequently
• Is getting worse
• Is associated with limping or instability

…it’s important to see your orthopaedic surgeon for assessment.

❓Quick Quiz (Single Best Answer):

Which type of hip replacement bearing is most commonly associated with squeaking?

A. Metal-on-polyethylene
B. Ceramic-on-polyethylene
C. Ceramic-on-ceramic
D. Metal-on-metal

🦴 Did you know? An artificial hip doesn’t just “sit” inside your body—it actually moves almost like a natural hip!

After a total hip replacement, the artificial ball rotates smoothly inside the artificial socket, helping people walk, climb stairs, sit, and return to many everyday activities with much less pain.

🎥 Watch this side-by-side animation to see how a natural hip and a hip replacement move during everyday motion.

❓Quick Quiz (Single Best Answer):

What is the most common reason people need a total hip replacement?

A. Hip arthritis causing pain and stiffness
B. A simple muscle strain
C. A sprained ankle
D. A broken wrist

🦿 THR Quick Quiz!

Which material is most commonly used to manufacture the femoral stem of a modern cementless Total Hip Replacement (THR)?

🔵 A. Stainless steel
🟢 B. Titanium alloy
🟡 C. Pure aluminium
🔴 D. Copper alloy

👇 Comment your answer before checking below!

✅ Correct Answer: B. Titanium alloy

Why?
Titanium alloys are widely used for cementless femoral stems because they are:
✔️ Strong yet lightweight
✔️ Highly biocompatible
✔️ Resistant to corrosion
✔️ Designed to encourage bone to grow onto the implant for long-term stability

Modern hip replacement implants are the result of advanced engineering, precision manufacturing, and rigorous quality testing to help restore mobility and improve patients’ quality of life.

How is a Total Hip Replacement (THR) implant made? 🦿⚙️

A hip implant doesn’t just appear—it goes through an incredible journey of engineering and precision.

🔹 Medical-grade titanium is forged into shape.
🔹 Advanced CNC robots machine every detail to micron-level accuracy.
🔹 Special porous coatings encourage bone to grow onto the implant.
🔹 Ceramic heads and highly cross-linked polyethylene liners provide smooth, durable movement.
🔹 Every implant undergoes rigorous quality testing before sterile packaging.

Modern hip implants combine engineering, materials science, and surgical innovation to help restore mobility and improve quality of life.

💬 Which part of the manufacturing process surprised you the most?

🦿 THR vs TKR – Can You Spot the Difference?

Although both procedures replace damaged joints and help people return to an active life, they are designed very differently.

🔹 Total Hip Replacement (THR): Replaces the ball-and-socket hip joint.
🔹 Total Knee Replacement (TKR): Resurfaces the damaged knee joint while preserving many of the surrounding structures.

❓ Orthopaedic Quiz

Which joint replacement generally allows patients to regain a more natural range of motion after a successful recovery?

🅰️ Total Hip Replacement (THR)
🅱️ Total Knee Replacement (TKR)
🅲 Both are the same
🅳 It depends only on age
