Why Can't We Just Replace Cartilage? Understanding Why Joint Replacement Is Sometimes Necessary

Why Can't We Just Replace Cartilage? Understanding Why Joint Replacement Is Sometimes Necessary

Many patients ask the same question: "If arthritis means cartilage is worn out, why can't you just replace the cartilage instead of replacing the entire joint?" In this episode, Dr. Matthew Sloan breaks down one of the biggest misconceptions about arthritis and explains why advanced hip and knee arthritis is much more than a cartilage problem. You'll learn why cartilage has such limited healing potential, how arthritis affects the entire joint, what injections and biologic treatments can realistically accomplish, and why modern joint replacement remains one of the most successful procedures in medicine. Dr. Sloan also explores the future of arthritis treatment, including regenerative medicine, stem cell therapies, AI-driven early detection, cartilage restoration techniques, and the possibility that future generations may need fewer joint replacements because arthritis is prevented before it ever becomes severe. Whether you're considering joint replacement, trying injections, or simply looking to understand your options, this episode provides a clear explanation of the science behind arthritis and the future of orthopedic care.

The Future of Joint Replacement: Robotics, AI, Recovery & Innovation with Dr. Michael Ast (HSS)

Dr. Matthew Sloan welcomes Dr. Michael Ast, Insall Chair of the Knee Service and Innovation Officer at Hospital for Special Surgery, for a wide-ranging discussion on the future of joint replacement surgery. Together they explore how robotics, artificial intelligence, outpatient surgery, implant technology, and modern recovery protocols are transforming the patient experience. Dr. Ast shares his perspective on: • The Quiet Knee Protocol and modern recovery strategies • Reducing opioid use after surgery • Robotic-assisted hip and knee replacement • AI-powered patient engagement and recovery monitoring • Same-day discharge and ambulatory joint replacement • Cementless implants and implant longevity • Partial versus total knee replacement • The future of revision surgery and custom 3D-printed implants • The impact of GLP-1 medications on orthopedic care • The importance of physician leadership in healthcare This conversation offers valuable insights for patients, surgeons, and anyone interested in where orthopedic surgery is headed over the next decade.

Dr. Yudi Kerbel — Social Media, Partial Knees, PNS & the Future of Joint Replacement

In Episode 17 of The Joint Replacement Podcast, Dr. Matthew Sloan welcomes fellowship-trained hip and knee replacement surgeon Dr. Yudi Kerbel, one of the most influential orthopedic educators on social media today. Dr. Kerbel shares how he built a platform that reaches millions of patients worldwide, why patient education is more important than ever, and how social media is transforming the relationship between surgeons and patients. The conversation dives deep into some of the most important topics in modern joint replacement, including: • When it's time to move from conservative treatment to joint replacement • How long modern hip and knee replacements really last • The "Less Swelling, Less Pain" recovery approach • Outpatient joint replacement and patient selection • Partial knee replacement versus total knee replacement • Why Dr. Kerbel believes many patients are excellent candidates for partial knees • Peripheral Nerve Stimulation (PNS) for painful knee replacements • Robotics, personalized alignment, and emerging technologies • Infection prevention and patient optimization • The emotional realities of being a joint replacement surgeon • The future of orthopedic surgery and musculoskeletal care Dr. Kerbel also shares his vision for helping patients avoid unnecessary surgery whenever possible and explains why he believes technologies like Peripheral Nerve Stimulation may dramatically change how orthopedic surgeons treat chronic knee pain in the future. Whether you're considering a hip replacement, knee replacement, partial knee replacement, or simply want a behind-the-scenes look at modern orthopedic surgery, this episode is packed with valuable insights for patients and surgeons alike.

Leadership, Infection Prevention & the Future of Joint Replacement | Dr. Antonia Chen

In this episode of the podcast, Dr. Matthew Sloan sits down with one of the most influential leaders in modern joint replacement surgery, Antonia Chen. Dr. Chen is the current president of American Association of Hip and Knee Surgeons and Chair and Professor of Orthopedic Surgery at UT Southwestern Medical Center. They discuss: * The future of hip and knee replacement * Periprosthetic joint infection prevention and treatment * Robotic vs manual joint replacement * Cementless knee replacements * Same-day discharge and outpatient joint replacement * Burnout and surgeon wellbeing * How patients should choose the right joint replacement surgeon * Recovery timelines, sports, and long-term implant longevity * The future of biologics and arthritis prevention Dr. Chen also shares her journey into orthopedics, her passion for research and mentorship, and her vision for the future of arthroplasty. This is an insightful conversation for patients, surgeons, trainees, and anyone interested in the evolving world of orthopedic surgery.

Simultaneous vs Staged Joint Replacement: Which Approach Is Safer?

Should you replace both knees or hips at the same time, or stage the surgeries separately? In Episode 15 of the Joint Replacement Podcast, Dr. Matthew Sloan breaks down the real clinical pros and cons of simultaneous bilateral joint replacement versus staged procedures. We discuss the physiologic stress of operating on both joints at once, differences in recovery and rehabilitation, complication risks, blood loss, anesthesia considerations, and which patients may — or may not — be good candidates for simultaneous surgery. Topics include: • Bilateral knee vs bilateral hip replacement • Recovery intensity and mobility challenges • Cardiac and pulmonary risks • Blood clot and transfusion considerations • Modern anesthesia and recovery protocols • Patient selection and surgical judgment • Why convenience should never outweigh safety If you or a loved one are considering joint replacement on both sides, this episode provides a practical, evidence-based look at how surgeons think through these decisions and what patients should realistically expect during recovery.
