Hip replacement surgery helps restore mobility and relieve pain in people with joint damage, often due to arthritis or injury. There are two primary types of hip replacement: traditional and minimally invasive. Each has unique techniques, recovery expectations, and ideal candidates.
At Orthopaedic Innovation, we specialise in minimally invasive surgery, exemplified by our Kley Rapid Hip approach - led by Dr Kristian Kley. We share more on his expertise further down.
What Is Traditional Hip Replacement Surgery?
How Is Traditional Hip Replacement Performed?
- Involves a 10–12 inch incision along the side or back of the hip
- Requires cutting or detaching muscles and tendons to access the joint
- The damaged bone and cartilage are removed and replaced with prosthetic components
- Longer operating time: surgery typically takes 1.5 to 2.5 hours (depending on the complexity)
What Are the Pros of Traditional Hip Surgery?
- Long-term success with a well-established track record
- Provides better access for the surgeon in complex cases
- Ideal for patients with significant joint damage or deformity
What Are the Cons of Traditional Hip Replacement?
- More tissue damage, resulting in longer recovery times
- Greater postoperative pain and blood loss
- Requires a longer hospital stay (typically 3–5 days)
- Higher risk of joint dislocation in some cases
- Higher risk of infection (due to operating time)
What Is Minimally Invasive Hip Replacement Surgery?
How Is Minimally Invasive Hip Surgery Different?
- Uses smaller incisions (3–6 inches)
- Aims to preserve muscles and tendons or only partially detach them
- Can be done using anterior, posterior, or lateral approaches:
- Anterior - from the front, avoiding major muscle disruption
- Posterior - from the back; more traditional but still muscle-sparing
- Lateral - from the side, balancing access and preservation
What Are the Benefits of Minimally Invasive Hip Replacement?
-
- Faster recovery with less tissue damage
- Reduced pain and smaller scars
- Shorter hospital stay; often same-day discharge
- Quicker return to activities and work
- Almost zero infections and dislocations
What Are the Drawbacks of Minimally Invasive Surgery?
- Technically demanding—requires experienced surgeons
- Requires specialized tools and imaging
- Potential risk of imprecise implant positioning if not done properly

What Is The “Kley Approach”?
At Orthopaedic Innovation, we have refined the minimally invasive model into what’s known as the Kley Approach. Spearheaded by Dr Kristian Kley and adapted from the Rottinger technique, this method integrates:
- Muscle-sparing incisions
- Advanced imaging and surgical precision
- Enhanced pain management
- Early mobilisation and prehabilitation
We believe this is the best type of hip replacement and implore you to read more about the Kley Approach on our website.
Below, we’ve included a comparison table of the Kley Approach against traditional approaches and standard minimally invasive approaches. Hopefully, this helps you figure out the best hip replacement for you.

What Have Surgeons Said About Minimally Invasive Techniques?
As aforementioned, at Orthopaedic Innovation our surgical team employs a highly effective minimally invasive technique called the Kley Rapid Hip.
Dr Kley’s approach is now being adopted as the best in class by many professionals. Here’s what Dr Vinay K Pandey had to say when he came to visit:
"As for surgical skills, it was truly mesmerising. I learned a lot”
This reflects the centre's outstanding results:
- 0% infection rate in the UK
- 0% blood clot rate in the UK
- 0% hip dislocation or fracture rate in the UK
You can hear from more surgeons on our Testimonials webpage.
Which Surgeon(s) Will I Have at Orthopaedic Innovation?
Our surgical team is steered by Professor Adrian Wilson and Dr Kristian Kley, two internationally recognised consultants with decades of combined experience in hip replacement procedure and various knee surgeries.
Together, they work as a close-knit team—consulting on complex cases, operating together and ensuring that every patient receives a tailored treatment plan based on the latest surgical innovation.
Totalling 20+ years of experience in minimally invasive hip replacements, it’s worth consulting us before deciding what type of surgery is right for you.
