But a study suggests that those long- held assumptions could be wrong. The study compared two groups of people with knee implants – those who ignored advice to take it easy on their new joints (called the sport group) and model patients who followed doctors' orders to avoid high- impact activities (the control group). Researchers found that after more than seven years there were no significant differences in wear or mechanical failure between the two groups. The research was presented at the 2. American Academy of Orthopaedic Surgeons in New Orleans, La.“We were a little bit surprised because we were not thinking that there would be absolutely no difference,” says lead author Sebastian Parratte, MD, Ph. D, an orthopaedic surgeon from the Mayo Clinic in Rochester, Minn., and the Aix- Marseille University, Center for Arthritis Surgery, Hospital Sainte- Marguerite in Marseille, France.“Before, everybody was thinking if you go running or something like that it will kill the prosthetic and don’t do that. Parratte says. Perhaps even more surprising is that researchers found that those who took part in the non- recommended sports actually showed higher knee and function scores than the control group. The control group had a higher rate of loosening, wear, fracture and overall mechanical implant failure than the sport group at 1. Adjusting for a variety of lifestyle factors, doctors say the sport group had a 1. The big news is that everybody before was thinking that doing high- activity sports would be terrible for the prosthetic of the patient and what we discovered was it was not terrible and indeed the patients that did high- level activity sports were doing better than others,” Dr. Parratte and his research team studied 2. Mayo Clinic and who admitted to their doctors that they either did heavy manual labor or took part in a high- impact sports that their doctor recommended they avoid. That group was compared to 3. Doctors evaluated all the participants’ implants and discovered that there were no significant radiological differences or differences in the durability of the implants between the groups.“It’s all about probabilities,” says Jason Dragoo, MD, an assistant professor of orthopaedic surgery at Stanford University Medical Center in Palo Alto, Calif., who specializes in sports medicine. Dragoo says he welcomes this study because it validates what he and other doctors have been hearing from patients for years.“There have been anecdotal reports that many clinics have been allowing their patients to do activities like skiing and playing tennis, there have been good results,” Dr. Parratte and his team say it’s likely due in part to better- made prostheses that are thicker and stronger than ones produced years ago. He also thinks the patients have something to do with it.“The patients practicing these kinds of sports were probably doing it before the prosthetics so they have experience and probably are more able to protect the prosthesis,” he explains. Two patients in the series were practicing and both needed a revision,” Dr. Dragoo says he does see one shortcoming with this study and that’s the fact that patients were only assessed after seven- and- a- half years.“It’s medium- term follow- up. But what we really need to do is show at 1. We need additional reports before we can come to the overall conclusion that this higher impact activity is safe,” Dr. It’s worthwhile reporting even though it doesn’t conclusively prove they are safe.”Bashir A. Zikria, MD, an assistant professor in the Department of Orthopaedics at Johns Hopkins University Medical Center who specializes in sports medicine also has concern about how long these study participants were followed. The thing you worry the most about is long- term. As far as wear, you don’t know wear analysis for at least 1. You will be asleep and pain-free during the procedure. Regional (spinal or epidural).

So for now, Dr. Zikria says this study doesn’t make him want to change his recommendations to patients who’ve had total knee replacements.“If they tell me at 1. I would change my opinion. But at seven- and- a- half years, it wouldn’t change the way I practice,” Dr. Parratte understands that it is too early to expect doctors to change their recommendations for knee replacement patients when it comes to what sports they should and should not take part in. But he says if further studies back up these results, it could happen someday.“It’s good news for the patient, good news for the surgeon; and we have to keep on working on this for the future,” Dr. The purpose of this study was to evaluate the outcome of total knee arthroplasty in patients with juvenile.
