In this small randomized trial of bicompartmental femoro-tibial arthritis, bi-unicompartmental arthroplasty gave no better 24-month patient-reported outcomes than cruciate-retaining TKA, with no major complications in either group.
In this 10-year randomized trial of uncemented TKA, highly crosslinked polyethylene showed no progressive wear after year five while conventional polyethylene wear continued, and component migration and outcomes were similar between groups.
Operative Outcomes of Cemented Hip Arthroplasty: An Examination of the French Paradox.
In 529 hip arthroplasties, cemented wedge-taper stems using the French Paradox technique showed low failure rates and less subsidence than uncemented stems, with similar readmissions and fracture rates.
Across 5,213 OTA meeting abstracts from 1996 to 2025, hip/proximal femur, geriatric, health-systems and periprosthetic topics rose while spine, pediatric and midfoot/hindfoot topics fell; RCT share stayed flat.
A 14-surgeon expert survey found consensus that disruptive bleeding after THA is best defined by care-altering events rather than blood-loss numbers, with disagreement on drainage thresholds and routine topical hemostatics; findings are exploratory.
In 429 robot-assisted TKAs, preoperative coronal phenotype explained only modest variability in initial gap balance and little in final balance, supporting direct intraoperative assessment over phenotype-based prediction.
Arthroscopic iliopsoas fractional lengthening gave satisfactory outcomes after THA regardless of the 8-mm acetabular overhang threshold, with low revision rates, supporting it as first-line surgery for refractory iliopsoas impingement.
In patients 70 and older, single-stage bilateral THA had longer stays and more transfusions than unilateral THA, but similar 90-day complications and one-year patient-reported outcomes, making it a reasonable option.
In 46 Vancouver B2/B3 periprosthetic femoral fractures revised with a modular tapered stem, 15-year survivorship was 95% with a 13% complication rate and 4% revision rate, supporting this as a viable option.
In 207 mUKA patients, slow early pain relief or slow early functional improvement strongly predicted worsening pain or function from years one to five, offering an early warning for closer follow-up.
In 165 TKA patients, kneeling ability afterward was predicted by preoperative exercise and kneeling habits, perceived importance of kneeling, and patellar-region sensory changes rather than surgical factors alone.
In 120 rotating-hinge TKAs, primary and revision cases both improved substantially in function and showed about 98% five-year survival, supporting selective use in complex knees despite no matched comparator.
Diaphyseal zonal fixation in revision total knee arthroplasty.
This paper proposes dividing the femoral diaphysis into three zones (distal diaphysis, isthmus, proximal diaphysis) to guide preoperative planning of durable fixation in complex revision knee arthroplasty and distal femoral replacement.
In 160 cemented bipolar hemiarthroplasty patients, acetabular depth under 20 mm and center-edge angle under 40 degrees independently predicted dislocation, which was linked to higher mortality; useful for preoperative risk stratification.
Short- to mid-term outcomes of total hip arthroplasty in high hip dislocations: does age matter?
In cementless THA for Crowe 3-4 high dislocations, patients 60 and older had more complications, mainly DVT, but similar function and revision-free survival; comorbidity (ASA 3), not age, predicted complications.
In a small case series, open gluteus medius repair after prior THA significantly improved hip scores and pain at about 4.5 years, with high satisfaction and only one repeat repair.
In this meta-analysis of 3,996 modular dual-mobility implants, intraprosthetic dislocation was rare (pooled about 0.1%), with no manufacturer differences detected, though data on non-Stryker implants were sparse and larger registry studies are needed.
Posterior cervical foraminotomy after cervical disc arthroplasty.
In 17 patients with prior same-level cervical disc arthroplasty, posterior cervical foraminotomy significantly reduced arm and neck pain without instability, though two (12%) later needed conversion to fusion.
Narrative review finding radiographs most available for post-THA cup anteversion, but CT with whole-pelvis imaging and a proper pelvic reference plane gives the most reproducible measurements, especially with abnormal spinopelvic mechanics.
This network meta-analysis of 691 fungal PJI cases found DAIR had significantly lower treatment success than one- or two-stage revision, with no clear differences among other strategies, suggesting DAIR be avoided.
This review finds phase II trials of factor XI/XIa inhibitors in orthopaedic surgery showed large VTE reductions with bleeding comparable to enoxaparin, and phase III trials will test their role in post-TKA prophylaxis.
Review of porous metal augments for acetabular defects in revision hip arthroplasty, reporting over 90% ten-year survivorship in severe defects, with concerns about debris at cup-augment interfaces and bone stock restoration in young patients.
Systematic review of 18 studies finds multiple periprosthetic joint infections are linked to 3+ prostheses, MRSA, and positive blood cultures, usually involve the contralateral knee with the same organism, and warrant close monitoring after an index PJI.
The Management of Neurological Injuries Following Total Hip Arthroplasty.
Review of nerve injury after total hip arthroplasty covering risk factors, imaging and electrodiagnostic workup, and supportive management, noting femoral nerve injuries have a better prognosis than sciatic nerve injuries.
Explains the new CMS patient-reported outcome-based performance measure for primary hip and knee arthroplasty, where hospitals capturing under 50% of PROMs risk Medicare payment loss, and offers strategies for compliance.
Consensus statements from the 2022 UK periprosthetic joint infection meeting's fracture-related infection session, reviewing each topic against current literature after delegates' anonymous electronic voting.
Review of periprosthetic tibial fracture after unicompartmental knee arthroplasty, a rare but serious complication, covering epidemiology, risk factors, and management strategies despite limited literature and surgeon unfamiliarity.
Robotic trials in arthroplasty surgery.
This annotation describes the RACER randomized trials comparing Mako robotic-assisted with conventional hip and knee arthroplasty, and discusses challenges such as blinding, learning curves, and cost-effectiveness assessment.
ACR/AAHKS guideline conditionally recommends against delaying hip or knee arthroplasty for more nonoperative care, but supports delay for smoking cessation and glycemic control; obesity alone isn't a reason to delay (low-quality evidence).
Occupational Hazards to the Joint Replacement Surgeon: Radiation Exposure.
Review of radiation exposure to arthroplasty surgeons from fluoroscopy, particularly direct anterior THA: doses are low and within limits, but no dose is truly safe, so shielding, minimal fluoroscopy time, and distance remain essential.
