Hip pain can make even daily activities like walking, climbing stairs, or getting out of a chair difficult. When medications, physiotherapy, and lifestyle changes no longer provide relief, hip replacement surgery can help restore mobility and improve quality of life.
Many people don’t realize there are different types of hip replacement procedures, surgical approaches, and implant options. The right choice depends on factors such as your condition, age, activity level, and overall health.
In this complete guide, you’ll learn what hip replacement is, why it’s needed, the different types of hip replacement surgery, their benefits, surgical approaches, recovery, and how to choose the best option for your needs.
What Is a Hip Replacement?
Hip replacement surgery — medically called total or partial hip arthroplasty — involves removing the affected surfaces of the hip joint and replacing them with artificial components that restore smooth, pain-free movement.
The hip is a ball-and-socket joint. The ball (femoral head) sits at the top of the thigh bone and moves within the socket (acetabulum) of the pelvis. When this joint becomes damaged by arthritis, fracture, or other conditions, simple movements like walking, climbing stairs, or sitting down become extremely painful — and eventually impossible.
Hip replacement relieves this pain permanently by replacing the worn joint surfaces with durable artificial implants designed to last 15-25+ years.
Why Do You Need a Hip Replacement?
Hip replacement is recommended when the hip joint is damaged to the point where daily function is severely limited and non-surgical treatments — physiotherapy, pain medication, and injections — no longer provide adequate relief.
Common conditions that lead to hip replacement:
- Osteoarthritis — the most common cause; cartilage wears away, leaving bone-on-bone contact
- Rheumatoid arthritis — autoimmune inflammation destroys the joint lining and cartilage
- Avascular necrosis (AVN) — blood supply to the femoral head is disrupted, causing bone collapse
- Femoral neck fractures — particularly in elderly patients following a fall
- Hip dysplasia — structural abnormality of the joint present since birth or childhood
- Post-traumatic arthritis — joint damage developing years after a hip injury
What Types of Hip Replacement Are There?
There are several distinct types of hip replacement surgery — each defined by how much of the joint is replaced and what materials are used. The right type depends on your age, activity level, the extent of joint damage, and overall health.
Total Hip Replacement (THR)
Total hip replacement is the most commonly performed type — replacing both the femoral head (ball) and the acetabular socket with artificial components. It is the gold standard for patients with widespread hip arthritis affecting the entire joint.
Components replaced:
- Femoral stem (implanted into the thigh bone)
- Femoral head (the ball — ceramic, metal, or oxidised zirconium)
- Acetabular shell (outer socket — titanium)
- Acetabular liner (inner bearing — polyethylene or ceramic)
Benefits of total hip replacement:
- Comprehensive, long-lasting pain relief
- 15-25 year implant lifespan with advanced materials
- Restoration of full hip range of motion for daily activities
- The most extensively studied hip replacement type with the largest long-term outcome dataset
Partial Hip Replacement (Hemiarthroplasty)
Partial hip replacement replaces only the femoral head — leaving the natural acetabular socket untouched. It is most commonly used for elderly patients with femoral neck fractures where a full joint replacement is unnecessary, or the patient’s health makes a shorter operation preferable.
Two subtypes:
- Unipolar (monopolar) hemiarthroplasty — a single-piece femoral head articulating directly against the native socket
- Bipolar hemiarthroplasty — a two-component femoral head with inner and outer bearings, reducing wear on the native cartilage
Benefits of partial hip replacement:
- Shorter operative time — reducing anaesthetic risk in elderly patients
- Less surgical complexity compared to total hip replacement
- Faster early mobilisation — walking begins within 24 hours in most cases
- Convertible to total hip replacement if acetabular wear develops over time
Revision Hip Replacement
Revision hip replacement replaces a previously implanted hip prosthesis that has failed — due to loosening, wear, infection, dislocation, or fracture of the implant. It is a more complex procedure than primary hip replacement, often requiring specialised augmented components to compensate for bone loss.
Benefits of revision hip replacement:
- Restores function when a primary implant has failed or worn out
- Uses specialised components to manage bone defects from previous surgery
- Extends mobility and pain relief for another 15-20 years in most cases
Total vs Partial Hip Replacement: Which Is Right for You?
| Feature | Total Hip Replacement | Partial Hip Replacement |
| Joint Replaced | Ball and socket | Femoral head (ball) only |
| Best For | Severe arthritis, joint degeneration | Femoral neck fractures, mainly in older adults |
| Surgery Time | Slightly longer | Shorter |
| Recovery | Moderate | Usually faster initially |
| Implant | Complete hip prosthesis | Partial prosthesis |
| Pain Relief | Excellent long-term relief | Effective for fracture-related pain |
| Implant Lifespan | 15–25+ years | May require conversion to total hip replacement in some cases |
| Ideal Patients | Active adults with damaged hip joints | Elderly patients with specific hip fractures |
Types of Hip Replacement by Surgical Approach
The surgical approach describes how the surgeon accesses the hip joint — and directly affects recovery speed, dislocation risk, and rehabilitation requirements.
Posterior Approach Hip Replacement
The most widely used surgical approach globally — access is from the back of the hip through the gluteal muscles. Provides excellent visualisation of the joint but carries a slightly higher dislocation risk that requires post-operative movement precautions.
Benefits:
- Extensive surgeon familiarity — very high procedural volume globally
- Superior visualisation for complex cases and revisions
- Suitable for most hip replacement patients regardless of anatomy
Anterior Approach (Direct Anterior) Hip Replacement
Access is gained from the front of the hip without cutting through major muscles — resulting in less muscle damage, faster recovery, and lower dislocation risk.
Benefits:
- Faster return to independent walking — typically 2-3 weeks ahead of posterior approach
- Lower early dislocation rate — no hip movement restrictions required post-operatively in most cases
- Less post-operative pain due to minimal muscle disruption
- Better suited for younger, active patients wanting the fastest possible recovery
Lateral Approach Hip Replacement
Access through the outer side of the hip — releasing the abductor muscles for joint exposure, then reattaching them after implantation.
Benefits:
- Lower dislocation rate than the posterior approach
- Good joint visualisation for primary and revision cases
- Historically popular in the UK and parts of Europe
Best Type of Hip Replacement for Older Adults
For patients over 70, the clinical priority shifts from maximum implant longevity to safety, speed of recovery, and appropriateness for medical comorbidities:
- Cemented total hip replacement is preferred — provides immediate fixation stability without relying on bone in-growth capacity that may be reduced in elderly patients
- Posterior or lateral approach is most commonly used — surgeons have the highest case volumes with these approaches
- Partial hip replacement (hemiarthroplasty) is appropriate for femoral neck fractures — shorter operative time reduces anaesthetic and cardiovascular stress
- Standard polyethylene bearings are appropriate — implant longevity is a secondary concern compared to surgical safety in the very elderly
Hip Replacement Procedure — What to Expect
Before surgery:
- Pre-operative assessment — blood tests, cardiovascular review, X-ray and CT templating
- Medication optimisation — stopping blood thinners, controlling blood sugar in diabetics
- Prehabilitation — building quadriceps and hip strength before surgery to improve recovery speed
During surgery:
- Anaesthesia — spinal anaesthesia is commonly preferred for hip replacement
- Operative duration — 60-90 minutes for primary total hip replacement; longer for revision cases
- Surgical protocol — approach, femoral preparation, component implantation, stability testing, closure
After surgery:
- Physiotherapy begins Day 1 — standing and walking with support within 24 hours
- Hospital stay — typically 2-4 days for standard primary hip replacement
- Recovery milestones — walking aids for 4-6 weeks, driving at 6-8 weeks, full activity at 3-6 months
Which Type of Hip Replacement Is the Best?
There is no universally “best” type of hip replacement — the optimal choice depends entirely on the individual patient’s requirements, anatomy, age, activity level, and clinical presentation:
- Younger active patients (under 60): Cementless fixation, ceramic-on-ceramic bearing, direct anterior approach for fastest recovery
- Active middle-aged patients (60-70): Cementless or hybrid fixation, ceramic-on-polyethylene bearing, anterior or posterior approach based on surgeon expertise
- Elderly patients (70+): Cemented or hybrid fixation, standard polyethylene bearing, approach based on surgeon familiarity
- Femoral neck fracture in elderly: Partial hip replacement (bipolar hemiarthroplasty), cemented stem, fastest possible mobilisation
- Failed prior hip replacement: Revision surgery with specialised augmented components
Frequently Asked Questions
1. What is the best type of hip replacement?
The best type depends on your age, activity level, and hip condition. Younger, active patients often benefit from a cementless total hip replacement, while elderly patients with hip fractures may be better suited for a cemented partial hip replacement. Your orthopedic surgeon will recommend the most suitable option.
2. What is the newest method of hip replacement?
Robotic hip replacement is one of the latest techniques. It combines 3D planning with robotic guidance to improve implant positioning, reduce tissue damage, and support faster recovery.
3. What is the safest hip replacement?
The safest hip replacement is one performed by an experienced orthopedic surgeon using the most appropriate technique for your condition. Direct anterior surgery has a lower dislocation risk, while cemented implants are often safer for patients with weak or osteoporotic bones.
4. What is the biggest complaint after hip replacement?
Most patients experience temporary stiffness, mild discomfort, and limited movement during the first few weeks. These symptoms usually improve with physiotherapy and rehabilitation as recovery progresses.
5. What is the new alternative to hip replacement?
For early-stage hip problems, treatments such as hip arthroscopy, osteotomy, and joint-preserving procedures may delay surgery. However, for modern arthritis, hip replacement remains the most effective long-term solution.
