When a hip becomes unstable after total hip arthroplasty, the orthopedic surgeon should investigate it with a history and physical, appropriate imaging and laboratory tests prior to any surgery to remove the hip anteversion or revise the prosthesis, according to a presenter.
As the rate of hip and knee arthroplasty procedures increases, so will the rate of interprosthetic fractures. Several factors, including bone quality, bone quantity, and stability of the prosthetic components, play a role in determining the appropriate operative treatment. Patients with stable components should undergo reduction and internal fixation, while patients with loose components should undergo either revision arthroplasty, with or without additional fixation, or conversion to total femur replacement
Study to evaluate outcomes of different hip replacement techniques using mobile gait analysis system
Researchers at Hospital for Special Surgery (HSS) have launched a pilot study using a portable gait analysis mat to determine early outcomes of several different hip replacement techniques. Gait analysis provides information about the way an individual walks.
Recently published results showed large variation in the rotational plane for both femoral and tibial components during 3-D unicompartmental knee arthroplasty component alignment analysis in the standing position, suggesting the importance of component positioning.
Consuming more dairy products may raise the risk for total hip arthroplasty for osteoarthritis (OA) in men, according to a study published in the Journal of Rheumatology.
Athletes such as Tiger Woods and Rafael Nadal are rumored to have undergone a relatively new treatment that involves injections of platelet-rich plasma. Proponents say the therapy offers cutting-edge treatment for previously debilitating injuries, including painful knee problems due to osteoarthritis.
In the first such collaboration of its kind, an expert panel of rheumatologists and orthopedic surgeons has developed guidelines for the perioperative management of anti-rheumatic medication in patients undergoing total hip or knee replacement.
Simultaneous bilateral total knee arthroplasty (BTKA) is often performed to treat patients with disabling arthritis of both knees.
Results of a study presented at European Society of Sports Traumatology, Knee Surgery and Arthroscopy Congress, here, showed patients who participated in sports before total knee arthroplasty were able to participate in sports postoperatively and in some cases, patients were more active in sports after surgery.
