The Past, Present, and Future of Hip Replacements

“The past is a foreign country. They do things differently there….”

Well, that’s certainly true in hip surgery! From early experiments with ivory in the 1800s to cutting-edge robotics today, hip replacements have come a long way. But how far, really? An article published in Hip International 30 years ago reflected on the first 30 years of modern hip surgery and speculated about the future. Now, 60 years on, let’s take a look at how far we’ve come—and what might lie ahead.

From Ivory to Innovation: A Brief History

The story begins in the 19th century when German surgeon Gluck experimented with ivory to replace the hip joints of people with tuberculosis. The idea was revolutionary, but without antibiotics, infections were rampant, leading to failure. The concept was abandoned, but it sparked a journey of innovation.

Modern hip replacements took shape in the 1950s, driven by pioneering surgeons and engineers across Europe and America. It was a time of trial and error. Sir John Charnley, working in Wrightington, was pivotal in developing a reliable system that made the operation reproducible and teachable worldwide. It wasn’t all smooth sailing—failures were common, but every setback led to better materials, improved techniques, and more consistent outcomes.

By 1995, hip replacements hadn’t changed much since Charnley’s days. Implants were made of stainless steel, titanium, and polyethylene. They worked well but didn’t last long in younger, active patients. Revision operations were often complicated, so surgeons delayed initial operations as long as possible. Metal-on-metal resurfacing was just emerging, met with both excitement and scepticism. It seemed like a game-changer.

Lessons Learned and Small Steps Forward

What did experts predict in 1995? They concluded three key lessons:

1.    Follow-Up Matters: Long-term monitoring of patients was crucial to understand how implants performed over time.
2.   Small Steps, Not Giant Leaps: Incremental improvements would be more effective than radical changes.
3.   Learn from Failure: Every failed hip replacement was an opportunity to learn, refine, and innovate.

They also noted the main causes of failure: dislocation, infection, and implant loosening due to wear. Their big question? Which materials would stand the test of time?

30 Years On: What’s Changed?

In some ways, not much. Implants still look quite similar, and they’re made from much the same materials. But the small steps have added up:

• Advanced Materials: Modern plastics and ceramics have virtually eliminated wear issues, significantly increasing implant longevity.
• Better Outcomes: Dislocation and infection rates have decreased, though not entirely eliminated.
• Learning from Mistakes: Metal-on-metal hips taught us hard lessons about the importance of rigorous testing and regulation. Today, new devices face much tighter scrutiny.
• Data-Driven Decisions: The National Joint Registry, set up 20 years ago, records every joint replacement in England and Wales. It tracks patient outcomes, helping surgeons make better choices and improving patient safety.

And then there are the changes no one saw coming…

The Unexpected Evolution

• Hip Super Specialists: Thirty years ago, hip surgery was mostly performed by general orthopaedic surgeons. Today, hip surgery is its own specialty, with hundreds of dedicated surgeons in the UK alone.
• Robotics and Rapid Recovery: Robots now assist with surgery, and patients are often home within a day or two, compared to a week or more in the past. This is critical as we face a rapidly aging population and stretched healthcare resources.
• A Younger Generation of Patients: More younger patients are opting for hip replacements, refusing to live with pain and disability. On the other hand , obesity is increasing, which raises complication risks.

The Future of Hip Surgery: A Glimpse into 2050

What will the next generation of surgeons be doing in 30 years?

• Day Surgery as Standard: Day case surgery will likely be the norm.
• Custom Solutions: 3D-printed prostheses tailored to each patient’s unique anatomy.
• AI and Precision Robotics: Enhanced accuracy, reduced pain, and faster recovery.
• Regenerative Medicine: Stem cells and gene therapy could repair cartilage and bone, potentially preventing the need for hip replacements altogether.
• Smarter Implants: Sensors could provide real-time data on joint function, improving personalized care.
• Global Impact: Advances in technology will make high-quality hip replacements more affordable and accessible worldwide.
