Randomized trials

  1. A prospective double-blinded randomized controlled trial comparing conventional jig-based versus robotic arm-assisted medial unicompartmental knee arthroplasty.RCT

    The Bone & Joint Journal · Sep 01 2026 · PubMed

    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.

New research

  1. Platform-specific learning curve and early tibial radiographic agreement of ROSA®-assisted medial unicompartmental knee arthroplasty in an experienced high-volume surgeon: a consecutive case series.

    Archives of Orthopaedic and Trauma Surgery · Sep 02 2026 · PubMed

    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.

  2. Patient, surgeon, and institutional variation in dual-mobility component use in primary total hip arthroplasty : a retrospective cohort study using data from the National Joint Registry Study.

    The Bone & Joint Journal · Sep 01 2026 · PubMed

    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.

  3. Impact of combined medial and lateral bone marrow lesions on clinical outcomes after medial unicompartmental knee arthroplasty : a retrospective cohort study.

    The Bone & Joint Journal · Sep 01 2026 · PubMed

    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.

  4. Secondary patella resurfacing following primary total knee arthroplasty : patient-reported outcomes, satisfaction, and patient-acceptable symptom state.

    The Bone & Joint Journal · Sep 01 2026 · PubMed

    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.

  5. Does transposition osteotomy of the acetabulum alter the natural history of developmental dysplasia of the hip?

    The Bone & Joint Journal · Sep 01 2026 · PubMed

    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.

  6. The Effect of Glucagon-like Peptide-1 Receptor Agonists in Total Joint Arthroplasty: Implications, Complications, and Considerations.

    Journal of the American Academy of Orthopaedic Surgeons · Sep 01 2026 · PubMed

    This review examines perioperative implications, complications, and management considerations for GLP-1 receptor agonist use in total joint arthroplasty patients.

  7. Hip arthroplasty following proximal femoral tumour resection in children : the impact of age and articulation on implant survival and the outcomes following acetabular revision.

    The Bone & Joint Journal · Sep 01 2026 · PubMed

    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.

  8. Five-year survival and complications of more than 300 articulating high-dose antibiotic spacers in two-stage revision total hip arthroplasties for infection.

    The Bone & Joint Journal · Sep 01 2026 · PubMed

    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.

  9. Meniscal Repairs Performed With Posterior Cruciate Ligament Reconstruction Are Associated With Lower Failure Rates Than Isolated Repairs.

    Arthroscopy · Aug 30 2026 · PubMed

    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.

  10. Osteotomies around the knee are associated with low short-term adverse event and reoperation rates: A 25-year national Hospital Episode Statistics analysis in England.

    Knee Surgery, Sports Traumatology, Arthroscopy · Aug 26 2026 · PubMed

    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.

  11. Clinical Outcomes of Fixed-Bearing Lateral Unicompartmental Knee Arthroplasty: A Retrospective Cohort Study With Up to 22-Year Follow-Up.

    Journal of Arthroplasty · Aug 26 2026 · PubMed

  12. Seiza Sitting After Total Hip Arthroplasty: Patient-Reported Outcomes and Three-Dimensional Kinematic Analysis.

    Journal of Arthroplasty · Aug 24 2026 · PubMed

    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.

  13. Incidence and Risk Factors for Periprosthetic Joint Infection in Patients Undergoing Primary Total Joint Arthroplasty Who have a History of Surgically Treated Periprosthetic Joint Infection in Another Joint.

    Journal of Arthroplasty · Aug 24 2026 · PubMed

    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.

  14. Outpatient and Early Discharge Revision Total Joint Arthroplasty: A Systematic Review and Pooled Quantitative Analysis.

    Journal of Arthroplasty · Aug 24 2026 · PubMed

    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.

  15. Determination of an Intraosseous Safe Corridor for Suprapubic Screw Placement in Total Hip Arthroplasty.

    Journal of Arthroplasty · Aug 24 2026 · PubMed

  16. Impact of Organism Profile on Ideal Timing of Reimplantation in Patients Undergoing Two-Stage Exchange Arthroplasty.

    Journal of Arthroplasty · Aug 19 2026 · PubMed

    Optimal interstage duration before reimplantation in two-stage knee PJI treatment varied by organism, with exceeding pathogen-specific cutoffs predicting treatment failure.

  17. Periprosthetic strain-adaptive bone remodeling of conservative metaphyseal fitting versus conventional anatomic cementless femoral stem.

    Hip International · Aug 14 2026 · PubMed

    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.

  18. Association of joint line changes with patient-reported outcomes after cruciate-retaining robotic arm-assisted total knee arthroplasty with functional alignment.

    The Knee · Aug 12 2026 · PubMed

    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.

  19. Risk factors for wound complications in direct anterior total hip arthroplasty: a 10-year analysis.

    Hip International · Aug 12 2026 · PubMed

    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.

  20. Modular intramedullary knee arthrodesis for chronic periprosthetic joint infection after total knee arthroplasty: Patient-reported satisfaction and functional outcomes.

    The Knee · Aug 12 2026 · PubMed

    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.
