Knee and Hip Replacement Surgery: Why Surgeon Volume and Fellowship Training Make All the Difference

Total knee replacement (TKA) and total hip replacement (THA) are among the most successful and life-changing procedures in medicine. Each year, hundreds of thousands of Americans undergo these surgeries to relieve debilitating pain from arthritis, restore mobility, and regain their quality of life. Yet not all outcomes are equal—and one of the biggest factors influencing your results isn’t the implant itself, but the surgeon performing the operation.

Choosing a surgeon with high procedural volume and specialized fellowship training in adult joint reconstruction isn’t just a preference—it’s backed by compelling evidence that directly translates to fewer complications, faster recovery, and better long-term success.

Understanding Knee and Hip Replacement

In total hip replacement, the damaged ball-and-socket joint is replaced with a prosthetic implant to eliminate pain and restore smooth motion.

In total knee replacement, the worn surfaces of the femur, tibia, and often the patella are resurfaced with metal and plastic components.

Both procedures have excellent success rates (over 90% of patients report significant pain relief and improved function), but complications such as infection, dislocation, implant loosening, uneven leg lengths, stiffness, or the need for revision surgery can occur. These risks drop dramatically when the procedure is performed by an experienced specialist.

Why Surgeon Volume Matters: “Practice Makes Perfect” Is Backed by Data

The “volume-outcome” relationship is one of the most consistent findings in orthopedic research: surgeons who perform more joint replacements each year achieve measurably better results.

Recent large-scale studies show that higher annual surgeon volume is associated with:

•  Significantly lower rates of complications, including prosthetic joint infection (PJI), dislocation, and early revision.

•  Shorter hospital stays and reduced healthcare costs.

•  Lower risk of 30-day and 90-day readmissions.

•  Improved patient-reported outcomes and implant longevity.

For example, one analysis found that complications continue to decrease as surgeon volume rises, with optimal thresholds often cited around 50–70 primary cases per year (and benefits extending even higher). Another 2025 study confirmed that high-volume surgeons performing total hip arthroplasty had lower short-term prosthetic joint infection rates and reduced all-cause revision risk compared to lower-volume colleagues. Similar patterns hold for knee replacement, where surgeons exceeding approximately 70 TKAs annually saw fewer early revisions and infections.

In contrast, the majority of joint replacements in the U.S. are still performed by surgeons operating well below these volumes—leaving many patients at higher risk without realizing it. Experience matters because it sharpens technical precision, improves intraoperative decision-making, and builds expertise in managing complex anatomy or unexpected challenges.

Why Fellowship Training in Adult Reconstruction Is a Game-Changer

Completing a one-year fellowship in Adult Reconstruction (also called Hip & Knee Arthroplasty or Joint Replacement Fellowship) after general orthopedic residency provides intense, focused training that general orthopedic surgeons simply don’t receive.

Fellowship-trained surgeons:

•  Master advanced techniques, including minimally invasive approaches, computer navigation, robotics, and complex revision surgery.

•  Gain extensive exposure to challenging cases (deformities, bone loss, prior surgeries, obesity, young active patients).

•  Learn evidence-based protocols for infection prevention, pain management, and rapid recovery.

A 2025 study published in The Journal of Arthroplasty found that patients undergoing total knee arthroplasty by fellowship-trained adult reconstruction surgeons experienced significantly decreased complications up to two years postoperatively compared to those treated by surgeons with other types of fellowship training or no fellowship. Additional research confirms lower overall complication rates, better implant alignment, and improved functional outcomes with this specialized expertise.

Fellowship training isn’t just extra letters after a name—it’s additional years dedicated exclusively to perfecting hip and knee replacement, which directly benefits patients through fewer revisions, faster return to activities, and greater confidence in long-term durability.

The Bottom Line for Patients in Charleston, SC

When it comes to knee or hip replacement, experience isn’t optional—it’s essential. High-volume, fellowship-trained surgeons deliver superior precision, fewer complications, and more reliable results.

In the Lowcountry, board-certified orthopedic surgeon Dustin Hambright, MD exemplifies this standard of excellence. A graduate of Duke University School of Medicine, he completed his orthopedic residency at the prestigious Harvard Combined Orthopaedic Residency Program and pursued specialized fellowship training in Joint Preservation, Resurfacing & Replacement at Washington University (Barnes-Jewish Hospital). Dr. Hambright focuses exclusively on hip and knee reconstruction and replacement, incorporating the latest evidence-based techniques—including computer navigation—to optimize outcomes for each patient. With experience in more than 5,000 hip and knee replacements in his career, he brings exceptional high-volume expertise to every procedure. He is currently accepting new patients at his practice locations in the Charleston area.

If you’re suffering from severe hip or knee arthritis and considering replacement surgery, don’t settle for just any orthopedic surgeon. Ask about annual case volume and fellowship training—these two factors can make the difference between a good result and an outstanding one.
