Hip arthroscopy with capsular plication for surgically confirmed microinstability produced patient-reported outcomes and revision rates comparable to matched non-instability arthroscopy controls at a minimum 2-year follow-up.
Despite worse clinical outcomes, patients undergoing revision TKA for stiffness had similar postoperative pain scores and opioid consumption compared to those revised for other aseptic reasons.
In a porcine model, a novel nano-coated 3D-printed mini-prosthesis for focal cartilage lesions showed superior cartilage protection and osseointegration compared with a standard CoCr implant or microfracture.
Reimplantation in 2-Stage Exchange: Breaking the Dogma of the 2-Week Antibiotic Holiday.
This review argues that a mandatory 2-week antibiotic holiday before reimplantation in two-stage exchange lacks outcome benefit, favoring continuous antibiotic therapy guided by clinical and serologic trends instead.
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 mouse model, vancomycin-loaded mesh significantly reduced staphylococcal infection after extensor mechanism reconstruction without compromising mesh strength, suggesting a promising future infection-prevention strategy.
An international 31-expert Delphi panel created the WAIT-Free Consensus, offering 13 practical recommendations to help low-adoption regions safely implement immediate weight-bearing after hip fracture surgery.
Cohort study found Exactech Equinoxe anatomic TSA implants had nearly double the revision risk versus other devices, even among non-recalled bags, though no difference was seen for reverse TSA.
In vitro testing showed PMMA cement brand and mixing sequence significantly affect vancomycin elution from high-dose spacers, with monomer-first Palacos MV maximizing cumulative release, informing spacer preparation for PJI treatment.
Robotic Arthroplasty in Context: Balancing Evidence and Innovation in Joint Replacement.
This review finds robotic-assisted arthroplasty improves component positioning precision but has not shown consistent gains in patient outcomes or implant survivorship, urging outcome-driven adoption over reliance on technical precision alone.
Patient-Reported Outcomes Following Custom Unicompartmental Knee Arthroplasty.
Custom UKA implants showed no PROM advantage over off-the-shelf components and had higher 2-year revision rates, largely due to aseptic loosening, questioning their added value.
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.
In this randomized trial, robotic-assisted functional alignment TKA produced modestly better 2-year patient-reported outcomes (function, satisfaction, pain) than conventional mechanically aligned TKA.
A single-position, fully anterior fix-and-replace strategy (pararectus fixation plus direct anterior THA) in 20 elderly patients with acetabular fractures achieved acceptable functional outcomes but a 20% two-year revision rate.
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.
This network meta-analysis found 1.5-stage revision had the best infection control but highest aseptic loosening risk, while two-stage revision had the lowest loosening risk but worse infection outcomes for periprosthetic joint infection.
In a district hospital study, hip log-roll and straight leg raise tests were highly sensitive but poorly specific for occult neck-of-femur fractures, useful mainly to rule out injury before CT/MRI.
This meta-analysis of 25 studies identifies male sex, obesity, diabetes, smoking, transfusion, high ASA score, and several perioperative factors as associated with periprosthetic joint infection after TKA.
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.
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.
Index hospitalization drives most 30-day bundled payment costs after joint arthroplasty, with readmissions and skilled nursing facility use as key postoperative cost targets for reduction.
ACL absence on preoperative MRI independently predicted worse mid-term Knee Society function scores after cruciate-retaining TKA, despite no significant impact on KOOS or Forgotten Joint Score.
Fix or Replace: Evidence for Treatment Options in the Management of Femoral Neck Fractures.
This review weighs evidence for internal fixation versus arthroplasty in femoral neck fractures, noting a growing trend toward arthroplasty based on injury and patient factors.
Normal or Not? Acetabular Morphology Is Not a Binary Classification.
This review argues that acetabular morphology measurements (like LCEA, Tönnis angle, and Graf classification) reflect a continuous dose-response risk rather than a simple normal/abnormal cutoff, challenging legacy diagnostic models.
Hip and Knee Arthroplasty in Patients with Obesity.
Reviews hip and knee arthroplasty in obese patients, emphasizing higher complication risk, the value of preoperative weight optimization (including bariatric surgery/GLP-1 agonists), and multidisciplinary perioperative care.
Golf After Total Hip and Knee Arthroplasty: Getting Back Into the Swing.
Reviews factors affecting return to golf after hip and knee arthroplasty, noting younger age, male sex, and lower BMI predict successful return with improved function.
Diagnosis and Management of Hand Infections.
This review addresses diagnosis and management of hand and upper-extremity infections, covering antibiotic timing, culture strategies, antibiotic stewardship, and emerging diagnostic technologies like next-generation sequencing.
This review summarizes the chemistry, commercial options, and clinical outcomes of PMMA bone cement to help surgeons optimize its use in hip and knee arthroplasty.
Current Concepts in Management of Distal Femur Fractures.
This review covers current surgical management trends for distal femur fractures, including locked plating, retrograde nailing, and newer nail-plate/double-plate constructs to reduce nonunion risk.
Techniques and results of reconstruction of femoral head fractures: An Update.
This review of 1403 femoral head fractures found surgical hip dislocation with the Ganz flip osteotomy offers the lowest complication rate and best functional outcomes, making it the preferred approach over anterior exposures.
This narrative review finds posterior cervical foraminotomy can be safely performed before or after cervical disk replacement without compromising stability, provided facetectomy stays under 50%.
Knee Arthroscopy After Prior Total Knee ArthroplastyType of Study: Narrative Review.
This narrative review outlines how arthroscopy can address specific post-TKA problems—peripatellar impingement, arthrofibrosis, and popliteus dysfunction—in select unsatisfied patients.
