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.
No significant differences in pain scores and mean morphine equivalent consumption were observed among patients who received either an intra-articular or periarticular injection of bupivacaine and morphine or a periarticular injection of liposomal bupivacaine to manage pain following unilateral total knee arthroplasty, according to a presenter here.
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.
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.
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.
Faculty from a recent ICJR symposium discuss planning and implementation of an outpatient joint replacement surgery program.
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.
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.
Investigators who studied outcomes following ACL reconstruction said they believe patients’ pre-injury status has been overlooked in determining postoperative results.
Satisfactory and similar subjective and objective clinical outcomes were reported in a study of patients who underwent primary ACL reconstruction with either hybrid graft or autograft.
Although results of this retrospective cohort study revealed more comorbidities in patients 90 years and older who underwent total hip arthroplasty compared with younger patients, nonagenarians had comparable rates of deep vein thrombosis, infection and pulmonary embolism. However, investigators cited the higher readmission rates of the oldest patients as need for closer postoperative follow-up.
