In hip-spine syndrome patients undergoing both lumbar fusion and total hip arthroplasty, doing spine surgery first was linked to modestly better 1-year hip outcome scores than hip-first sequencing.
In hip osteoarthritis patients, patient-defined outcome goals varied by age—seniors prioritized low-intensity activities while younger adults sought high-intensity function—highlighting the value of PDOs alongside standard PROMs to align treatment expectations.
In a single-center cohort, Medicare Advantage patients had longer hospital stays than traditional Medicare patients after elective hip/knee arthroplasty, with discharge disposition strongly modifying this relationship.
In 3,302 THA/TKA patients, osteopenia carried an intermediate reoperation risk between normal BMD and osteoporosis, showing a graded relationship between lower preoperative BMD and worse two-year outcomes.
In a cohort study, tourniquet use during primary TKA independently and dose-dependently increased early postoperative quadriceps inhibition, alongside higher BMI and longer operative time.
Withholding antibiotics until intraoperative cultures are obtained during PJI resection reduced culture discordance and improved reimplantation success (90% vs 79.6%) compared to giving antibiotics beforehand.
Aortic Stenosis and Total Hip Arthroplasty Complications: The Role of Perioperative Medications.
In THA patients with aortic stenosis, 30-day complications (especially stroke and cardiac events) were higher, and day-of-surgery TXA reduced transfusion/infection risk while certain antihypertensives raised stroke risk.
This systematic review found the Zimmer Biomet Compress device has periprosthetic fracture rates (2.7-3.9% in adults) comparable to or lower than cemented stems, with fractures clustering in the first 2 years and a stable bone-implant interface aiding revision.
10-Year Follow-Up Outcomes of a Modular Dual-Mobility in Primary Total Hip Arthroplasty.
Modular dual-mobility bearings in primary THA showed excellent 10-year functional outcomes, no dislocations, and no bearing-related failures, supporting their use in instability-prone patients.
In a multi-institutional cohort, neurosurgeons obtained hip radiographs less often and missed radiographically evident hip pathology more frequently than orthopaedic surgeons before spine surgery, supporting more structured hip-spine screening.
Patients with advanced patellofemoral chondrosis had similar patient-reported outcomes after meniscus root repair but nearly 7-fold higher rates of conversion to knee arthroplasty.
At minimum 10-year follow-up, hip arthroscopy without capsular repair for stable FAIS showed 90.7% survivorship, though female sex, higher BMI, and Tönnis grade predicted worse outcomes.
This meta-analysis of over 20,000 cases found CT-guided robotic-arm-assisted UKA had a low complication rate (3.8%) and fewer overall complications than manual UKA (5.5%), supporting its safety.
In 180 TKA patients, two-week JKOM scores and pain levels strongly predicted four-week functional recovery, suggesting early PROM assessment could guide individualized rehab and risk stratification.
This systematic review found that in patients under 60 with acetabular fracture ORIF, conversion to THA occurs a mean of ~5 years later with good but time-limited implant survivorship (95% at 5 years, declining to 70-80% at 15 years) and higher complication rates than primary THA.
Despite greater intraoperative lateral than medial laxity in mechanically aligned medial-pivot TKA, fluoroscopic gait analysis showed preserved neutral coronal alignment and stability with no condylar lift-off during mid-stance.
A 1-year prospective study found preoperative muscle strength, not radiographic osteoarthritis severity, best predicted gait speed recovery after THA/TKA, supporting strength assessment in surgical planning.
A novel 3D-printed, fiducial-based testing model standardizes evaluation of imageless CA-TKA navigation systems, showing both tested systems achieved good cut-surface uniformity but more variability in sagittal alignment.
In a matched cohort, fixed-bearing UKA gave comparable two-year outcomes for spontaneous osteonecrosis and osteoarthritis, though larger necrotic lesions in SONK patients may require extra femoral fixation support.
Risk Factors for Readmission Following Same-Day Discharge in Primary Total Hip Arthroplasty.
In 11,245 THA patients, same-day discharge had lower 90-day readmission overall, but smoking and older age disproportionately raised readmission risk in this group, warranting careful patient selection.
Diagnosis of aseptic loosening after hip arthroplasty : international Delphi consensus.
A 37-surgeon international Delphi panel reached consensus on 25 clinical and radiological criteria for diagnosing aseptic THA loosening, endorsing radiographs first-line and CT for uncertain cases.
This review outlines the surgical challenges (exposure, hardware, deformity, bone loss, stability) and outcomes of complex TKA for posttraumatic osteoarthritis, noting good pain/function gains but higher complication and revision rates.
Narrative review highlights that perioperative nutritional strategies—vitamin D/C repletion, magnesium, flavonoids, and amino acid supplementation—can reduce complications and speed recovery after total joint arthroplasty.
Reviews new CMS policies mandating patient-reported outcome measure (HOOS JR/KOOS JR) reporting for outpatient/ASC hip and knee arthroplasty starting 2025-2027.
This AAOS guideline summary provides evidence-based recommendations on dental screening, antibiotic prophylaxis, and procedure timing to prevent periprosthetic joint infection after hip or knee arthroplasty.
Reviews the chemistry behind dilute povidone-iodine irrigation, explaining why diluted solutions paradoxically boost free molecular iodine and antimicrobial activity while reducing tissue toxicity, supporting its use to prevent surgical site infections.
Contemporary insights into spinopelvic mechanics.
This review highlights how individualized assessment of spinopelvic mechanics, advanced imaging, and implant selection can help surgeons reduce dislocation risk and improve outcomes after total hip arthroplasty.
Review supports perioperative corticosteroids (8-16 mg dexamethasone equivalent) in THA/TKA for reduced nausea, pain, and opioid use with neutral-to-positive effects on other outcomes, despite transient hyperglycemia without clear infection risk.
This review updates a classification system for cemented femoral stems (taper-slip vs composite beam subtypes) to standardize comparison of designs and guide future development.
This review outlines patient selection tools, neuraxial anesthesia, multimodal analgesia (fascia iliaca and adductor canal blocks), and ERAS protocols that support safe, faster-discharge outpatient total joint arthroplasty.
