The increasing prevalence of obesity has resulted in an increased number of revision total hip arthroplasties (rTHAs) performed in patients with a high body mass index (BMI)…
In our study, severe obesity was associated with an increased risk of infection following RevisionTHA. Patients with high BMI should be counseled appropriately before surgery.
Only a few small studies have been published on pregnancies after total hip replacement…
…The aim of our study was to evaluate whether maternal total hip replacement affects pregnancy outcomes on a population-based level…
…Neonates born after maternal total hip replacement have an increased risk of stillbirth, small for gestational age, low birthweight and preterm birth. Trial of labor is more likely to end in emergency cesarean section.
Study Finds 60% of Hip Implants Last 25 Years. After reviewing thousands of case studies going back 25 years across six countries, researchers at the University of Bristol say they indicate that eight out of 10 total knee replacements (TKRs) and six out of 10 total hip replacements (THEs) will still be in place after 25 years.
7-year evaluation of a new formulation of vitamin E-diffused highly crosslinked polyethylene
March 14, 2019 LAS VEGAS — At the American Academy of Orthopaedic Surgeons Annual Meeting, Charles R. Bragdon, PhD, associate director of clinical studies and director of Partners’ Orthopedic Registries at Harris Orthopaedic Laboratory at Massachusetts General Hospital, spoke about results of a 7-year evaluation of a new formulation of vitamin E-diffused highly crosslinked polyethylene.
He said that results of the prospective, blinded, randomized controlled trial of 67 patients indicate that in contrast to conventional polyethylene, which is minimally crosslinked and wears at 0.1 mm per year, this formulation of polyethylene and others before it essentially have undetectable wear over time.
“Wear is no longer a function time,” he said. “It is not a function of head size. It is not a function of body weight. We have been able to remove the wear from the equation of …

After reviewing thousands of case studies going back 25 years across six countries, generalisable survival data is now available for the first time to estimate how long hip and knee replacements are likely to last.
This involved the reports of 215,676 people whose cases were followed up for 15 years after undergoing total hip replacements; 74,052 who were followed up for 20 years; and 51,359 who were followed up for 25 years.
Of the total hip replacements, 89 per cent were found to last 15 years, 70 per cent lasted 20 years, and 58 per cent lasted 25 years…
December 31, 2018 ORLANDO — At the Current Concepts in Joint Replacement Winter Meeting, Jeffrey B. Stambough, MD, discussed a study that looked at long-term outcomes of two consecutive groups of patients who underwent total hip arthroplasty with either conventional polyethylene or highly crosslinked polyethylene bearings. He said after a 15-year follow-up, highly crosslinked polyethylene bearings were an effective solution after patients younger than 50 years old underwent THA.…
August 2, 2018 – A long-term follow-up study from Australia confirms that hip implants with components made of cross-linked polyethylene (XLPE) substantially lower the risk of revision surgery after total hip replacement, reports a study in the August 1, 2018 issue of The Journal of Bone & Joint Surgery. The journal is published in the Lippincott portfolio in partnership with Wolters Kluwer.
“The use of XLPE has resulted in a significant reduction in the rate of revision at 16 years following total hip arthroplasty for osteoarthritis,” writes Professor Richard de Steiger, MBBS, FRACS, FAOrthA, and colleagues of the Australian Orthopaedic Association National Joint Replacement Registry, Adelaide, South Australia. With less wear and better longevity than implants using conventional polyethylene (CPE) components, the superior durability of XLPE implants may encourage total hip replacement to be performed in younger patients.
Cross-linked polyethylene bearing surfaces were developed to address the …
June 6, 2018 – For elderly trauma patients, a basic goal is early mobilization, as immobilization can trigger various complications, such as venous thromboembolism, pneumonia, urinary tract infections, and pressure ulcers. Although partial weight-bearing has been shown to significantly increase mortality compared with unrestricted weight-bearing, it remains a frequent recommendation of aftercare following lower-extremity fracture fixation…
…Elderly patients seem to be unable to maintain weight-bearing restrictions. As early mobilization of geriatric trauma patients is an important element for a successful rehabilitation, the directive of postoperative partial weight-bearing for these patients should be abandoned.…
June 6, 2018 – Obesity is a negative prognostic factor for various surgical procedures. The purpose of this study was to compare patients with obesity who underwent hip arthroscopy for femoroacetabular impingement and labral tears with a match-controlled group of normal-weight patients…
…Hip arthroscopy for the treatment of femoroacetabular impingement and labral tears in patients with obesity yielded significant improvements at ≥5 years; these results were similar to a matched group of normal-weight patients. However, patients with obesity demonstrated a twofold increased risk of conversion to total hip arthroplasty.…
