Total knee arthroplasty (TKA) has been an effective treatment for patients with advanced degenerative joint disease. During the past 4 decades, changes in TKA materials, designs, and instrumentation systems have been incremental with an intention to improve technique consistency, functional implant performance, and implant survival.
Adults are at higher risk for major osteoporotic fracture if one of their parents experienced a hip fracture, particularly if that fracture occurred at a younger age, according to recent study findings.
In a historical cohort study, William Leslie, MD, MSc, FRCPC, professor of medicine and radiology at the University of Manitoba in Winnipeg, Manitoba, Canada, and colleagues analyzed data from all Manitoba residents aged at least 40 years between 1997 and 2014 with continuous health care coverage and linkage to at least one parent through the publicly funded health care insurance database (261,705 offspring; 48.3% women; 478,792 parents).

Now new research shows that stem cells could one day be stimulated to make a special type of cartilage to help repair large, hard-to-heal bone fractures. Muscle and Medicine reported that hundreds of NFL players have invested in using stem cells to treat injuries. The publication revealed one NFL linebacker ‘paid $6,000 a pop for a 1-milliliter vial of donated placenta tissue containing stem cells to be injected into each of his beat-up knees.’
Older men with an increasing number of specific risk factors 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. Researchers followed the cohort for incident hip fractures (regardless of trauma level) for a mean of 8.6 years; questionnaires were administered by telephone or mail every 3 years, and hip fractures were verified by physician adjudication of medical records.

A Loyola Medicine study suggests it may not be necessary for knee replacement patients to wait up to two weeks after surgery before showering, as many surgeons now require.
The study compared patients who were allowed to shower two days after surgery with patients who had to wait 10 to 14 days. Researchers performed bacterial culture swabs of skin next to incisions, and no differences were found between the early-shower and delayed-shower groups. No patient in either group experienced an infection. As expected, patients overwhelmingly preferred being allowed to shower early.
Results from this randomized controlled trial showed both low- and high-intensity plyometric exercise for rehabilitation following ACL reconstruction positively affected knee function, knee impairments and psychological status among patients after 8 weeks of intervention.Researchers randomly assigned 24 patients who underwent ACL reconstruction to 8 weeks of either low- or high-intensity plyometric exercise, and the groups were distinguished by the anticipated magnitude of vertical ground-reaction forces. Investigators assessed patient outcomes with the IDKC subjective knee form and a biomarker for articular cartilage degradation.
Excellent clinical outcomes were seen after fresh osteochondral allograft transplantation in patients with articular cartilage damage of the femoral trochlea, according to study results. Researchers used an osteochondral allograft (OCA) database and identified 28 patients (72.4% were male patients) treated with a fresh OCA transplant for the femoral trochlea. The mean follow-up was 7 years. Investigators used the Kaplan-Meier method to calculate allograft survivorship.

The surgical approach to total hip replacement (THR)—either from the front of the body or the side/back (anterior versus posterior)—has no impact on outcomes six months after surgery, according to research presented today at the 2016 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS).

The use of opioids (narcotic pain medication), often prescribed for chronic musculoskeletal pain, has skyrocketed in recent years with 98 percent of the world’s opioid prescriptions filled in North America. Two research studies presented this week at the 2016 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), link decreased opioid use prior to joint replacement surgery with improved patient satisfaction and outcomes, fewer complications, and a reduced need for post-surgical opioids.

Anesthesiologists can significantly reduce loss of muscle strength in ACL knee surgery patients using a new pain management technique, a new study has found.
