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.
Lima Corporate announced the completion of the assets acquisition from Zimmer Holdings for the Zimmer Unicompartmental High Flex Knee and the Biomet Discovery Elbow System within the European Economic Area and Switzerland markets, as well as the Biomet Vanguard Complete Knee System for Denmark and Sweden.
Prevention of osteoporosis is essential to health, quality of life, and independence in the elderly. The accepted diagnostic method for evaluation of fracture risk after osteopenia and osteoporosis is the measurement of bone mineral density with dual-energy x-ray absorptiometry (DEXA). This method is limited because of its low accessibility, high capital costs, and low sensitivity. This study evaluated whether canal diameter is a reliable indicator as a major risk factor for hip fracture in the elderly.
Many patients who underwent total knee arthroplasty did not experience improvement in their gait relative to preoperative patients by 12 months postoperatively; however, use of routine gait analysis was helpful for guiding patients’ postoperative rehabilitation and may be useful for developing strategies for mobility improvement, according to researchers’ findings.
Among patients who underwent total joint arthroplasty required to follow the Medicare 72-hour-stay rule, 47.88% were safe for discharge to a skilled nursing facility by postoperative day 2, according to results presented at the American Orthopaedic Association Annual Meeting.
Residents who trained with cadaveric skills labs and simulators experienced improved performance in knee arthroscopy compared with residents who did not, according to results presented at the American Orthopaedic Association Annual Meeting.
Standardized anteroposterior radiographs were insufficient for the accurate assessment of the mechanical alignment of total knee arthroplasty compared with hip-knee-ankle radiographs. Additionally, anteroposterior radiographs exaggerated the varus appearance of mechanical alignment in implants, according to study results.
Compared with primary total knee arthroplasty, revision unicompartmental knee arthroplasty was correlated with poorer outcomes; however, researchers theorized this may have been a result of poorer preoperative function.
Most patients’ brake reaction time had returned to baseline level or better within 2 weeks of undergoing total hip arthroplasty, allowing the patients to be able to drive safely again, according to study results.
Complicated revision total hip arthroplasty (THA) and total knee arthroplasty (TKA), septic prosthetic failure, and periprosthetic femoral fractures seem to be increasing. The expanding applications for arthroplasty in younger patients coupled with their longer lifespan is translating into more revision procedures. In addition, with the increasing population of older patients and the increasing number of THA and TKA procedures done in this population prostheses are being used in more osteoporotic bone and the incidence of periprosthetic fractures is increasing.
