A stepwise femoral head extraction technique using a Schanz pin and corkscrew minimized tensor fasciae latae injury in 63 direct anterior hip arthroplasties.
Crowe I developmental dysplasia and primary osteoarthritis show comparable THA outcomes; preoperative function predicts MCID achievement.
Amyloid in Primary Hip Arthroplasty Specimens: An Opportunity for Early Detection of Amyloidosis?
Routine THA specimens may incidentally harbor amyloid including cardiac transthyretin subtype, representing an opportunity for early detection and treatment of a now-targetable systemic disease.
After THA for dysplastic hip osteoarthritis, residual pelvic obliquity is driven by leg lengthening in upward-tilted cases and by spinal deformity/reduced lumbar flexibility in downward-tilted cases.
Postoperative COX-2 inhibitors appear safe in chronically anticoagulated THA patients, showing no increased bleeding or complication risk and reduced opioid use through 180 days.
At 2 years, dual-mobility THA using the Trinity system showed high patient satisfaction and low, clinically insignificant blood metal ion levels, supporting its safety and efficacy.
In a matched cohort of 166 patients, simultaneous bilateral THA had similar complication and readmission rates as staged bilateral THA but significantly shorter total length of stay, supporting its safety.
An international Delphi consensus among revision hip surgeons identified visible component motion under stress maneuvers as the key intraoperative sign of hip arthroplasty component loosening, standardizing assessment for future research.
In cementless short-stem THA, cortical hypertrophy correlated with better functional scores in patients under 60 but had no impact in those over 75, suggesting it's an adaptive response in younger, active patients rather than a problem.
A propensity-matched cohort study found technology-assisted primary THA had modestly higher index and 90-day episode-of-care costs than manual THA, with only slightly shorter hospital stays.
A history of GI bleeding before hip or knee arthroplasty was linked to higher 90-day medical complications and increased 2-year risk of mechanical loosening/revision (THA) or PJI/revision (TKA).
Patients needing both lumbar fusion and total hip arthroplasty had delayed clinically meaningful recovery, but performing lumbar fusion before THA (rather than after) resulted in recovery timelines closer to THA-only patients.
Registry analysis of over 238,000 THAs found surgeon and hospital factors, not patient characteristics, mainly drive variation in dual-mobility implant use, highlighting a need for evidence-based selection criteria.
In pediatric proximal femoral endoprosthetic reconstruction, pre-adolescents had poor implant survival regardless of articulation, while THA outperformed hemiarthroplasty in adolescents despite a higher early dislocation risk.
In over 300 two-stage THA revisions for infection, a commercial articulating antibiotic spacer achieved 89% five-year reinfection-free survival, though spacer dislocation strongly predicted subsequent dislocation after reimplantation.
In 22 pediatric cerebral palsy patients, THA provided durable pain relief over an average 11-year follow-up with an acceptable 22% complication rate, supporting its use in select cases of painful hip dislocation.
Pregnancy, Sexuality, and Total Hip Arthroplasty: Experiences of Women Younger than 45 Years.
In young women who underwent THA, most subsequent pregnancies and vaginal deliveries were safe, and nearly half reported improved sexual satisfaction post-surgery due to reduced pain and better mobility.
Better hip range of motion, stronger quadriceps, and less pain at 3 months after THA predicted higher (better) Forgotten Joint Score-12 at one year, highlighting early rehab targets.
In a national database study, patients with Down syndrome undergoing primary THA had excellent 10-year implant survivorship (94.6% revision-free) comparable to matched controls, supporting THA as durable in this population.
Survey and 3D kinematic analysis of THA patients found Seiza sitting is biomechanically feasible with adequate implant clearance, though dislocation anxiety often prevents patients from resuming it.
CT analysis of 27 THA patients defines a reproducible suprapubic intraosseous safe corridor for supplemental screw fixation, offering practical angular guidance to avoid neurovascular injury.
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.
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.
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 two-center study of 391 older femoral neck fracture patients undergoing THA, a validated nomogram using anticoagulant use, TXA administration, surgical duration, and preoperative hemoglobin accurately predicted postoperative transfusion risk (AUROC 0.90).
A preoperative CTA-based algorithm with selective endovascular intervention (balloon catheters or arterial coiling) safely mitigated vascular injury risk during revision THA in patients with intra-pelvic implant migration.
In a no-BMI-cutoff center, BMI ≥40 patients had higher infection, reoperation, and revision rates after THA, but this risk was largely driven by greater comorbidity burden, supporting individualized rather than strict BMI-based patient selection.
In a large propensity-matched database study, robotic-assisted THA in patients with lumbar fusion or stiff spine showed lower rates of prosthetic complications, dislocation, transfusion, and revision compared to manual THA, supporting robotic precision in this high-risk group.
Risk factors for wound complications in direct anterior total hip arthroplasty: a 10-year analysis.
Among 725 direct anterior THAs, higher BMI, longer surgical time, and surgeon inexperience predicted wound complications, while prophylactic negative pressure wound therapy did not reduce risk and complications correlated with higher PJI and revision rates.
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.
Dislocations after total hip-replacement arthroplasties.
In 300 total hip replacements, dislocation risk was lowest with acetabular cup placement in a 'safe zone' of 15±10° anteversion and 40±10° abduction, especially within the first postoperative month.
Ectopic Ossification Following Total Hip Replacement
In this 1973 study, 21% of THA patients developed ectopic bone by 6 months, but it impaired function only when frank ankylosis occurred.
Health-Related Quality of Life in Total Hip and Total Knee Arthroplasty
This systematic review of 74 studies confirms THA and TKA reliably improve health-related quality of life, with hip arthroplasty and primary surgery yielding greater gains than knee arthroplasty or revision surgery.
Prevalence of Total Hip and Knee Replacement in the United States
About 7 million Americans live with hip or knee replacements; prevalence increases dramatically with age and is higher in women, reflecting substantial public health impact.
Functional Results of Hip Arthroplasty With Acrylic Prosthesis
Early hip arthroplasty outcomes depend on restoring normal femoral neck length and preventing prosthetic loosening; new cervico-capital designs distribute pressure to reduce bone absorption.
