What is the Surgical Procedure for a Total Hip Replacement (THR)?
Step-by-Step Guide to Total Hip Replacement Surgery by Dr. Abhishek Bhalotia
Hip pain can significantly affect mobility, independence, and overall quality of life. Activities such as walking, climbing stairs, sitting cross-legged, or even getting out of bed may become painful in patients suffering from severe hip arthritis or hip joint damage.
In such cases, Total Hip Replacement Surgery (THR) is considered one of the most effective and successful orthopaedic procedures.
According to Dr. Abhishek Bhalotia, understanding the actual surgical procedure for Total Hip Replacement helps patients feel more confident, informed, and mentally prepared before surgery.
This guide explains the step-by-step procedure of Hip Replacement Surgery, recovery expectations, and important aspects patients should know before undergoing a Total Hip Replacement (THR).
What is Total Hip Replacement Surgery?
Total Hip Replacement Surgery, also known as THR Surgery or Hip Arthroplasty, is a procedure in which the damaged portions of the hip joint are replaced with artificial implants.
The surgery is commonly recommended for:
- Severe Hip Arthritis
- Osteoarthritis of Hip
- Avascular Necrosis (AVN Hip)
- Rheumatoid Arthritis
- Hip Joint Damage after Injury
- Chronic Hip Pain affecting daily life
The primary goals of Hip Replacement Surgery are:
✔ Pain relief
✔ Improved mobility
✔ Better joint function
✔ Restoration of quality of life
Understanding the Hip Joint
The hip is a ball-and-socket joint.
- The ball = head of the femur (thigh bone)
- The socket = acetabulum (part of the pelvis)
In arthritis or AVN, the smooth cartilage covering these surfaces gets damaged, leading to:
- Pain
- Stiffness
- Grinding sensation
- Difficulty walking
During Total Hip Replacement Surgery, these damaged surfaces are replaced with artificial components called implants.
Step-by-Step Surgical Procedure for Total Hip Replacement (THR)
1. Pre-Operative Planning
Successful Hip Replacement Surgery begins before entering the operation theatre.
Dr. Abhishek Bhalotia emphasises detailed:
- X-ray evaluation
- Joint alignment analysis
- Implant sizing
- Surgical planning
Pre-operative planning helps improve implant positioning and surgical precision.
2. Anaesthesia Before Surgery
The patient is usually given:
- Spinal Anaesthesia
or - General Anaesthesia
The anaesthesia team continuously monitors:
- Blood pressure
- Heart rate
- Oxygen levels
throughout the procedure.
3. Surgical Exposure of the Hip Joint
The surgeon carefully approaches the hip joint using a selected surgical technique.
In many modern cases, surgeons may use muscle-sparing approaches such as the:
- Direct Anterior Approach Hip Replacement
These approaches aim to minimise soft tissue damage and support faster recovery in selected patients.
4. Removal of Damaged Joint Surfaces
The damaged portions of the hip joint are removed carefully.
This includes:
✔ Damaged femoral head
✔ Arthritic cartilage
✔ Diseased bone surfaces
The goal is to prepare the joint accurately for implant placement.
5. Implant Placement
Artificial hip implants are then positioned precisely.
The implants generally include:
- Acetabular Component (socket)
- Femoral Stem
- Femoral Head Component
Modern Hip Replacement Implants are designed for:
- Smooth movement
- Long-term durability
- Better stability
Precise implant alignment is critical for successful outcomes after Total Hip Replacement Surgery.
6. Joint Stability and Movement Check
Before completing surgery, the surgeon checks:
- Joint movement
- Hip stability
- Leg length balance
- Implant positioning
This step helps ensure proper functional movement after surgery.
7. Closure of the Surgical Site
After confirming stability and alignment:
- Soft tissues are repaired carefully
- The incision is closed
- Sterile dressing is applied
The patient is then shifted to recovery monitoring.
What Happens After Hip Replacement Surgery?
Recovery starts early after surgery.
Most patients begin:
✔ Standing
✔ Walking with support
✔ Physiotherapy exercises
within a short period after surgery, depending on medical condition and surgical protocol.
Benefits of Total Hip Replacement Surgery
Patients undergoing Hip Replacement Surgery may experience:
- Significant reduction in pain
- Improved walking ability
- Better joint movement
- Improved independence
- Enhanced quality of life
Modern Total Hip Replacement procedures are designed to help patients return to functional daily activities safely.
How Long Does THR Surgery Take?
The duration varies depending on:
- Complexity of the case
- Joint damage severity
- Surgical approach used
In most cases, the surgery typically takes a few hours including preparation and recovery monitoring.
Final Thoughts
Total Hip Replacement Surgery (THR) is one of the most reliable and successful procedures for patients suffering from severe hip pain and arthritis.
As Dr. Abhishek Bhalotia explains, successful outcomes depend on:
- Proper patient selection
- Detailed surgical planning
- Accurate implant positioning
- Structured rehabilitation
Patients who understand the procedure and actively participate in recovery often experience significant improvement in mobility and quality of life after Hip Replacement Surgery.
