Satisfactory results seen in revision THA with acetabular reinforcement, HA granules, autograft
Using acetabular revision for loosening as an endpoint, investigators of this study found more than 90% acetabular component survival at 10 years among patients who underwent revision total hip arthroplasty for acetabular bone deficiency using a Kerboull-type acetabular reinforcement device to support hydroxyapatite granules and structural autograft.
Study shows value of knee replacement surgery, other options
Source: Medical Xpress
People with knees worn out by arthritis will get more pain relief from joint replacement surgery, but it has more risks and there's a good chance that less drastic approaches also would help. That's the bottom line from the first study to strictly test other treatments against knee replacement, an operation done hundreds of thousands of times a year in the U.S.
Activity could help keep knees lubricated

Cartilage is filled with fluid -- about 80% of the volume of the cartilage tissue -- that plays the essential roles of supporting weight and lubricating joint surfaces. Loss of this fluid, called synovial fluid, results in a gradual decrease in cartilage thickness and increase in friction, which is related to the degradation and joint pain of osteoarthritis. Since cartilage is porous, fluid is readily squeezed out of the holes over time. Yet the symptoms associated with osteoarthritis usually take decades to develop. Researchers have now proposed a mechanism that explains how motion can cause cartilage to reabsorb liquid that leaks out.
Prevalence of Total Hip and Knee Replacement in the United States
Background: Descriptive epidemiology of total joint replacement procedures is limited to annual procedure volumes (incidence). The prevalence of the growing number of individuals living with a total hip or total knee replacement is currently unknown. Our objective was to estimate the prevalence of total hip and total knee replacement in the United States.
The use of bisphosphonate drugs is associated with an increased risk of atypical hip fractures
Source: Medical News Today
The use of bisphosphonates, a group of drugs used to prevent hip breakages in women with osteoporosis, is associated with an increased risk of atypical fractures in this joint, understood as those that occur in less frequent locations. It has been established thus in the PhD thesis by Javier Gorricho-Mendívil, a graduate in pharmacy, and read at the NUP/UPNA-Public University of Navarre. The author advocates encouraging other preventive measures such as "strategies to reduce falls and an active lifestyle to improve bone density and health"
A 48-year-old woman with right knee pain
A 48-year-old woman with a history of hypertension, rheumatoid arthritis treated with chronic prednisone, and a two-pack-per-week cigarette use, presented to clinic with 8 years of right knee pain. She had an intra-articular steroid injection with some relief 6 years ago. She denied any hip pain and uses a cane for ambulation. On physical examination she appears to be a healthy 5’2’’, 160-pound woman who walks with an antalgic gait. She has a 20° flexion contracture, with flexion limited to 90°, and a mild valgus deformity of her knee. The extremity was neurovascularly intact and she had full, painless hip range of motion.
THE CHANGING LANDSCAPE OF JOINT REPLACEMENT
The International Congress for Joint Reconstruction (ICJR) recently sponsored a CME symposium, accredited by Marshall University, designed to help orthopaedic surgeons understand the steps involved in planning and implementing an outpatient joint replacement surgery program.
THE LEARNING CURVE FOR THE DIRECT ANTERIOR APPROACH
Few joint replacement surgeons were exposed to the direct anterior approach for total hip arthroplasty during their residency and fellowship – which means they’ll need additional training if they want to offer this approach to their patients.
Women fare better than men following total knee, hip replacement

While women may have their first total joint replacement (TJR) at an older age, they are less likely to have complications related to their surgery or require revision surgery, according to a new study presented today at the 2015 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). The findings contradict the theory that TJR is underutilized in female patients because they have worse outcomes then men.
Hip Fracture Patients: Nearly half have delirium, study suggests

48 percent of hip fracture patients, age 65 and older, had delirium, or acute confusion, before, during and after surgery (perioperative), resulting in significantly longer hospital stays and higher costs for care, a new study concludes.
