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.
According to the Arthritis Foundation, over 50 million Americans have arthritis. The most common form of arthritis is osteoarthritis, which is a degenerative joint disease. Though it can occur in younger people, it often affects people 50 years of age and older.
The authors state: "While there are certainly controversies in the field of osteoporosis, there are also issues upon which there is complete or near-complete agreement: specifically, there is consensus that patients with hip fracture should receive pharmacological treatment to prevent additional fractures, as they are clearly at risk for recurrent hip or other osteoporotic fractures, and initiation of bisphosphonate therapy after hip fracture has been shown to reduce the risk of a second hip fracture."
Three-hundred thirty-two thousand Americans have hip replacement every year. For most, the surgery requires a hospital stay, and weeks of rehabilitation. Now, a different approach to surgery is getting patients back on their feet and out of the hospital faster than ever before.
Older men with an increasing number of specific risk factures combined with decreased bone mineral density at the femoral neck are at elevated risk for hip fracture, according to study findings. Jane A. Cauley, DrPH , professor and vice chair for research in the department of epidemiology at the University of Pittsburgh Graduate School of Public Health, and colleagues analyzed data from 5,876 men not assigned osteoporosis medications at baseline who participated in the Osteoporotic Fractures in Men (MrOS) study, a multicenter, prospective study of risk factors for fractures.
Fibrocartilage tissue in the knee is comprised of a more varied molecular structure than researchers previously appreciated, according to a new study by researchers from the Perelman School of Medicine at the University of Pennsylvania and the University of Delaware.
Patients who received a newer prosthesis similar to the Miller-Galante knee design showed significantly better Knee Society function scores than patients who had a long-used prosthesis to which it was compared. However, the two implants performed about the same at short-term follow-up, according to a presenter.
The longer a hip fracture patient stays in a hospital, the more likely that patient will die within 30 days of leaving, according to a study led by Stephen Kates, M.D., chair of the Department of Orthopaedic Surgery at the Virginia Commonwealth University School of Medicine.
Men have many reasons to add high-impact and resistance training to their exercise regimens; these reasons include building muscle and shedding fat. Now a University of Missouri researcher has determined another significant benefit to these activities: building bone mass.
A new study, published November 15, in the journal Pain provides information on the trajectories of prescription drug use before and after hip-replacement surgery-total hip arthroplasty (THA), one of the most common types of joint replacement surgery.
