Campbell Research Helps Surgeons Know Which New Products Deliver on Promises
"In this field, clinical data seriously lags behind product introduction," said Dr. John Crockarell, a Campbell Clinic surgeon and researcher whose clinical studies help orthopaedic surgeons make informed judgments about what new products will produce the best outcomes over time.
In the last year, Dr. Crockarell analyzed information from Campbell Clinic patients to produce two studies that have been accepted for publication. Using radiographic analysis, Dr. Crockarell learned that Reflection® cementless acetabular components did not wear as well and had higher revision rates that newer polyethylene products. His findings will be published in the Journal of Arthroplasty.
Dr. Crockarell's view of the Contour® reconstruction ring confirmed some of the limitations of this type of device. The American Journal of Orthopaedics will publish his findings in this study.
Change Begs for Research
Dr. Crockarell has seen major changes in total joint replacement since he began practicing at Campbell Clinic in this specialty in 1997. In addition to improvements in the design and materials of implant devices, the decade has brought a greater emphasis on minimally-invasive surgery and better pain management, Dr. Crockarell said.
"Orthopaedic surgeons are always seeking better products and techniques if they mean better outcomes for patients," Dr. Crockarell said. "Clinical research helps us see how a product actually performs once the implant is done. This kind of information is always valuable to the surgeon and of great benefit to the patient."

In the rapidly-evolving orthopaedic specialty of total joint replacement, clinical data is the tortoise and new products are the hare.
