In a randomized trial, robotic-assisted medial UKA achieved more accurate component positioning, less pain, shorter hospital stay, and better mid-term Forgotten Joint Scores than jig-based UKA, though standard PROMs were similar.
In a case series of 30 patients, an experienced surgeon reached proficiency with ROSA-assisted medial UKA by the sixth case, with excellent early tibial radiographic accuracy versus plan.
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 medial UKA patients selected by MRI, mild concomitant lateral bone marrow lesions did not worsen mid-term pain, function, or alignment outcomes compared to isolated medial lesions.
Secondary patella resurfacing after TKA produced meaningful improvements in knee scores and quality of life with high satisfaction, especially when performed more than 2.5 years after the index arthroplasty.
Transposition osteotomy improved 20-year joint survival in dysplastic hips but did not significantly benefit borderline dysplastic hips, suggesting dysplasia severity should guide patient selection for surgery.
This review examines perioperative implications, complications, and management considerations for GLP-1 receptor agonist use in total joint arthroplasty patients.
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 a large database study, meniscal repairs combined with PCL reconstruction had significantly lower failure and revision rates than isolated meniscal repairs, similar to benefits seen with concomitant ACL reconstruction.
A 25-year English HES analysis found knee osteotomy has low 90-day and 1-year reoperation/complication rates, with higher comorbidity burden predicting serious complications.
In 113 fixed-bearing lateral UKAs followed up to 22 years, implant survivorship remained high (87% at 20 years) with significant, durable improvements in Oxford Knee Scores.
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.
In patients with prior surgically treated PJI in another joint, subsequent primary TJA carried a low 1.5% one-year PJI rate comparable to controls, though prior one/two-stage revision (versus DAIR) and higher comorbidity burden raised risk.
Pooled analysis suggests carefully selected, healthier patients can safely undergo outpatient/early-discharge revision hip and knee arthroplasty with equal or lower complication rates than inpatients.
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.
Optimal interstage duration before reimplantation in two-stage knee PJI treatment varied by organism, with exceeding pathogen-specific cutoffs predicting treatment failure.
In patients under 50 followed 20+ years, conventional anatomic cementless femoral stems caused significantly more stress-shielding bone loss than conservative metaphyseal-fitting stems, though both had similarly excellent clinical outcomes and survivorship.
In robotic-assisted CR-TKA using functional alignment, medial joint line elevation (but not lateral changes) was linked to worse 1-year patient-reported outcomes, suggesting surgeons should avoid unnecessary medial elevation while modest depression appears acceptable.
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.
In 15 patients treated with cemented modular intramedullary nail knee arthrodesis for chronic PJI, infection control and stability were reliably achieved with good satisfaction, though taller patients and those with more prior surgeries fared worse psychologically.
This review argues that choosing between one- and two-stage exchange for chronic hip PJI should weigh patient treatment burden and institutional protocol capability rather than relying solely on traditional selection criteria, given comparable infection-eradication rates at experienced centers.
Outpatient Total Joint Arthroplasty: Future Directions.
This review discusses how advances in perioperative care and anesthesia have enabled outpatient total joint arthroplasty to achieve outcomes and cost-efficiency comparable to inpatient surgery with proper patient selection.
From surgical backlog to opioid burden : the case for opioid stewardship in arthroplasty pathways.
Annotation argues for opioid stewardship throughout arthroplasty care pathways to counter rising perioperative opioid reliance amid prolonged surgical wait times.
This scoping review of 35 studies finds preoperative GLP-1 receptor agonist use in orthopaedic surgery is generally associated with similar or lower complication, infection, and readmission rates, though spine surgery outcomes are mixed.
Describes lessons learned in developing the first international, evidence-based ARCO clinical practice guideline for nontraumatic femoral head osteonecrosis, emphasizing consensus-building, resource-stratified recommendations, and lifecycle implementation.
This primer reviews how AI and machine learning are being applied across hip and knee arthroplasty care—from risk prediction to robotic guidance—while noting current limitations in validation and clinical integration.
This review summarizes perioperative management of chronic antithrombotics in TJA, noting strong support for continuing aspirin but a lack of high-quality evidence guiding postoperative resumption of anticoagulants and P2Y12 inhibitors.
Iliopsoas Tendonitis and Impingement After Total Hip Arthroplasty.
This review covers causes, diagnosis, and treatment options—from conservative care to tenotomy or revision—for iliopsoas impingement/tendinitis after total hip arthroplasty.
This review argues that shorter antibiotic courses and earlier oral transition may be as effective as prolonged therapy for periprosthetic joint infection, though evidence quality remains limited.
Optimizing debridement and implant retention in acute periprosthetic joint infections.
This review argues that debridement, antibiotics, and implant retention remains a viable option for acute periprosthetic joint infection, and outlines key factors (timing, staging, team, antibiotics, implant considerations) that optimize DAIR success.
