Procedure Overview
What Does “Surgical Approach” Mean?
In total hip replacement surgery, the term surgical approach refers to the pathway the surgeon uses to access the hip joint.
This determines where the incision is made and how muscles are handled during surgery.
Importantly:
- The same artificial hip components are used regardless of approach
- The goals of surgery are the same: pain relief, improved mobility, and better quality of life
- Long-term outcomes are excellent with both approaches when performed well
Surgical Approaches Covered on This Page
The two most commonly used approaches in Dr Grammatopoulos’ practice are the:
- Anterior approach
- Posterior approach
Which approach is recommended for you will be based on what is safest and most appropriate for your anatomy and medical factors.

Incision Details
Location and Size of the Incision
The location and length of the incision differ between the posterior and anterior approaches. Incision size can vary depending on patient anatomy, surgical complexity, and surgeon preference. A smaller incision does not necessarily mean a better or safer operation.- Posterior Approach Incision
- Located at the side/back of the hip, slightly toward the outer side of the buttock
- Typically curves gently along the natural contours of the hip
- Average length is usually 8-15 cm, but this can vary
- Positioned to allow good access to the hip joint and safe implant placement
- Located at the front of the hip, near the groin and upper thigh
- Usually in a horizontal, ”bikini”, incision
- Average length is often 8–12 cm, but this also varies
- Positioned between natural muscle planes
- Incision length is influenced by safety and visibility, not cosmetic preference alone
- All incisions are closed carefully to promote good healing
- Scars typically fade over time, though appearance varies between individuals
Surgical Approaches
Which Approach Is Best?
There is no single best approach for all patients. Research shows that:- Long-term results are similar for posterior and anterior approaches
- Surgeon experience and implant positioning are more important than the approach itself
- Individual anatomy, medical conditions, and safety considerations matter most
Anterior Approach Preferred
- The incision is made at the front of the hip
- The surgeon works between natural muscle planes, often without cutting major muscles
- Specialized operating tables or equipment may be used
- Less muscle disruption during surgery
- Often fewer formal movement restrictions after surgery
- Some patients experience faster early mobility and recovery
- Low risk of hip dislocation
- Not suitable for all patients, depending on anatomy, body shape, or bone structure
- Technically more demanding and highly dependent on surgeon experience
- Temporary numbness or tingling on the front or side of the thigh may occur due to irritation of a superficial nerve
- Early walking and physiotherapy begin soon after surgery
- Many patients are allowed to move more freely early on, but activity progression is still guided
- Long-term outcomes and implant durability are excellent and comparable to other approaches
Posterior Approach Preferred
- The incision is made at the back of the hip
- The surgeon works through muscles at the back of the hip, which are carefully separated and repaired at the end of surgery
- This is the most widely used approach worldwide and is very well studied
- Excellent visualization of the hip joint, allowing accurate implant positioning
- Suitable for a wide range of patients and body types
- Long track record with decades of supporting evidence
- Reliable and reproducible technique
- Slightly higher risk of hip dislocation in the early recovery period
- Temporary movement precautions may be recommended, such as:
- Avoiding deep bending at the hip
- Avoiding twisting the leg inward
- These precautions are usually short-term and guided by your care team
- Walking typically begins the day of or the day after surgery
- Physiotherapy focuses on strength, balance, and safe movement
- Long-term recovery and implant longevity are excellent and comparable to other approaches
What This Means For You
- Which approach do you recommend for me and why?
- Will I have any movement precautions?
- How might this affect my recovery and return to activities?
Comparison: Posterior Approach vs Anterior Approach
| Feature | Posterior Approach | Anterior Approach |
|---|---|---|
| Incision location | Back of the hip | Front of the hip |
| Typical incision length | ~8–15 cm | ~8–12 cm |
| Muscle handling | Muscles separated and repaired | Muscles moved aside |
| Muscle handling | Often recommended | Often fewer |
| Early dislocation risk | Slightly higher | Low |
| Patient suitability | Most patients | Selected patients |
| Long-term outcomes | Excellent | Excellent |
Preparing for Surgery
Medical Preparation
- Attending a preoperative assessment clinic to review your overall health. This may require blood tests, X-rays, and heart tests.
- Reviewing medications with your healthcare provider, as some may need to be stopped before surgery.
- Managing existing conditions (such as diabetes, anemia, high blood pressure, or heart disease) as well as possible
- Treating existing infections (including dental, skin, or urinary infections) before surgery
Lifestyle Preparation
- Stop smoking, ideally several weeks before surgery, as smoking can delay healing and increase risk of complications
- Maintain a healthy diet rich in protein, vitamins, and minerals to support healing
- If advised, try to lose excess weight to reduce stress on the new joint
- Begin preoperative exercises ("prehabilitation") to strengthen hip and leg muscles and improve flexibility
Plan Ahead
- Arrange time off work and discuss return-to-work plans with your healthcare provider
- Organize help at home for the first few weeks after surgery
- Plan transportation to and from the hospital on the day of surgery and for follow-up appointments. You will not be able to drive initially.
- Prepare questions and concerns to discuss with your surgical team
What to Expect After Surgery
Recovery In Hospital
- Most patients stay in hospital for 0-2 days.
- Pain will be managed with medications.
- You will stand and begin walking with assistance (walker/crutches) immediately.
- Physiotherapy starts early to restore movement.
- Blood-thinning medication may be used to reduce clot risk.
Recovery At Home
- Continue prescribed physiotherapy exercises daily.
- Gradually increase walking and activity as advised.
- Use walking aids until your surgeon says they are no longer needed.
- Experience mild to moderate pain and swelling (common for several weeks).
- Avoid certain movements to reduce dislocation risk.
- Keep the surgical wound clean and dry.
Return to Work, Driving & Sports
Return to Work
- Sedentary work: 4–6 weeks
- Light physical work: 6–8 weeks
- Heavy manual labour: 8–12 weeks+
Driving
- You are no longer taking narcotic pain medication
- You can safely control the vehicle and perform an emergency stop
- Your surgeon confirms it is safe
Sports
- Walking
- Swimming
- Cycling
- Lower-impact fitness programs
Frequently Asked Questions
Does the approach affect how long my hip replacement lasts?
No. Implant longevity depends on many factors but is not determined by the surgical approach alone.
Can the approach be changed during surgery?
In rare situations, the surgeon may adjust the approach for safety reasons.
Should I choose a surgeon based on the approach they use?
It is generally best to choose a surgeon who is experienced and comfortable with the approach they use most often.
