One of the most fascinating aspects of modern medicine is how quickly the relationship between physicians and patients is evolving. In Episode 17 of The Joint Replacement Podcast, I had the opportunity to sit down with fellowship-trained hip and knee replacement surgeon, Dr. Yudi Kerbel, whose educational content has reached millions of patients worldwide.
What started as a way to educate his own patients has grown into one of the largest orthopedic education platforms online. During our conversation, Dr. Kerbel shared insights on patient education, social media, partial knee replacement, peripheral nerve stimulation (PNS), robotics, and the future of joint replacement surgery.
Why Social Media Matters in Healthcare
Patients today have access to more medical information than ever before. According to Dr. Kerbel, the challenge is no longer access to information—it’s finding trustworthy guidance.
Rather than relying solely on office visits, patients increasingly turn to online resources, videos, podcasts, and social media platforms to better understand their conditions and treatment options.
For Dr. Kerbel, creating educational content became a way to:
- Help patients understand arthritis and joint replacement
- Answer common questions before appointments
- Improve healthcare literacy
- Build trust before patients ever step into the office
His experience highlights an important shift in healthcare: patients increasingly seek partnership and education, not simply recommendations.
When Is It Time for Joint Replacement?
One of the most common questions orthopedic surgeons hear is:
“How do I know when it’s time for surgery?”
Dr. Kerbel’s answer was refreshingly simple:
“I treat patients, not X-rays.”
While imaging findings are important, the decision to proceed with surgery should ultimately be based on quality of life.
Questions patients should ask themselves include:
- Is pain limiting daily activities?
- Have conservative treatments stopped working?
- Is arthritis preventing participation in activities that matter most?
- Has quality of life significantly declined?
When arthritis begins controlling a patient’s life rather than merely inconveniencing them, it may be time to discuss surgical options.
How Long Do Modern Joint Replacements Last?
Many patients still believe joint replacements only last 10–15 years.
However, modern data paints a much more encouraging picture.
A large systematic review published in The Lancet demonstrated that approximately:
- 90–95% of hip replacements remain functioning at 20 years
- More than 90% remain functioning at 30 years
The Lancet
Dr. Kerbel emphasized that many patients receiving contemporary implants may never require another operation during their lifetime.

The Case for Partial Knee Replacement
One of the most passionate portions of our discussion centered on partial knee replacement.
Many patients develop arthritis isolated to a single compartment of the knee. Historically, many of these patients still received total knee replacements.
Dr. Kerbel believes appropriate candidates should strongly consider partial knee replacement because it:
- Preserves healthy bone and ligaments
- Maintains more natural knee kinematics
- Often provides faster recovery
- Allows greater activity levels
- Feels more like a normal knee
Not every patient qualifies, but for carefully selected individuals, partial knee replacement can be an outstanding option.
Peripheral Nerve Stimulation: A Potential Game Changer
Perhaps the most exciting topic discussed was Peripheral Nerve Stimulation (PNS).
PNS uses a small implanted device to deliver targeted stimulation to nerves responsible for chronic pain.
Dr. Kerbel described its use in patients with:
- Persistent pain after knee replacement
- Painful arthritis who are poor surgical candidates
- Chronic knee pain not responding to traditional treatments
One nerve receiving particular attention is the infrapatellar branch of the saphenous nerve, which may play a significant role in certain painful knee conditions.
The most intriguing aspect of PNS is that many systems allow patients to undergo a temporary trial before committing to permanent implantation.
While additional research is ongoing, PNS may offer selected patients an alternative to major revision surgery.

Rethinking Recovery After Surgery
Dr. Kerbel has also adopted concepts from the “Less Swelling, Less Pain” philosophy.
The central idea is simple:
Swelling is the enemy.
Rather than aggressively pushing activity immediately after surgery, the approach emphasizes:
- Elevation
- Ice
- Swelling control
- Early motion
- Gradual progression
The goal is to reduce inflammation during the critical early postoperative period and create a smoother recovery experience.
Although protocols vary among surgeons, the broader message is that recovery should be individualized rather than one-size-fits-all.
The Future of Joint Replacement
Several exciting innovations were discussed, including:
Robotics
Robotic-assisted surgery continues to improve precision and personalization in joint replacement procedures.
Augmented Reality
Emerging technologies may allow surgeons to visualize implant positioning in real time.
Advanced Implant Materials
Future implant surfaces may reduce bacterial adhesion and potentially lower infection risk.
Biologics and Regenerative Medicine
Long-term, orthopedic care may increasingly focus on preserving joints rather than replacing them.
As Dr. Kerbel noted, the ultimate goal should be:
“How can we do less?”
In other words, how can we restore quality of life while minimizing invasiveness and maximizing patient outcomes?
The Human Side of Joint Replacement Surgery
One of the most powerful moments in the episode came when discussing what patients often don’t realize about surgeons.
Dr. Kerbel emphasized that complications affect surgeons deeply.
Joint replacement surgery is incredibly rewarding when patients return to activities they love. But when complications occur, surgeons carry that burden as well.
That emotional investment is something many patients never see.
Final Thoughts
Episode 17 highlights why patient education remains one of the most powerful tools in healthcare.
Whether discussing social media, partial knee replacement, peripheral nerve stimulation, robotics, or future innovations, Dr. Yudi Kerbel’s message was consistent:
The goal is not simply performing surgery. The goal is improving lives.
For patients considering hip or knee replacement, and for surgeons interested in the future of orthopedic care, this episode offers valuable insight into where the field is heading next.
