    Clinical Orthopaedics and Related Research · Jul 20 2026 · PubMed

    For elderly patients with displaced femoral neck fractures, THA offers no clinically important functional benefit over hemiarthroplasty and increases dislocation risk; hemiarthroplasty is preferred.

    Journal of Arthroplasty · Jul 15 2026 · PubMed

    Robot-assisted total knee arthroplasty achieves comparable functional outcomes and low complications in HIV-positive and HIV-negative patients when viral suppression is maintained.

  11. Does Cement Viscosity Influence 10-year Outcomes in Primary Total Knee Arthroplasty Under Standardized Surgical Technique?

    Journal of Arthroplasty · Jul 14 2026 · PubMed

    Cement viscosity was not independently associated with 10-year revision risk for aseptic loosening or radiographic fixation in primary TKA using standardized techniques.

  12. Determining the Mechanical Axis of the Femur from a Standard Antero-posterior Knee Radiograph with Deep Learning.

    Journal of Arthroplasty · Jul 14 2026 · PubMed

    Deep learning model predicts femoral mechanical axis from standard antero-posterior knee radiographs with 1.02-degree accuracy, outperforming linear regression and 6-degree varus methods.

  13. Undernourished and Underweight: Independent Predictors of Worse Outcomes Following Total Hip Arthroplasty.

    Journal of Arthroplasty · Jul 13 2026 · PubMed

    Underweight and malnourished patients undergoing total hip arthroplasty face significantly higher risks of bleeding, cardiac arrest, and death, amplified when both conditions coexist.

  14. Functional alignment robotic-assisted total knee arthroplasty with tibial varus limited to 6° yields greater early postoperative pain improvement in patients with preoperative MPTA ≥84° compared with MPTA <84°.

    The Knee · Jul 09 2026 · PubMed

    Robotic-assisted functional alignment total knee arthroplasty yields comparable early outcomes regardless of tibial varus severity, with modest pain improvement in less severe deformities.

  15. Functional Outcomes Following Bipolar Hip Hemiarthroplasty via the Direct Anterior Approach Versus Posterior and Direct Lateral Approaches: A Retrospective Cohort Study.

    Journal of Orthopaedic Trauma · Jul 02 2026 · PubMed

    A propensity-matched cohort found the direct anterior approach for bipolar hip hemiarthroplasty offered better early functional recovery at discharge than posterior approach, but differences did not persist at 12 months.

  16. Kneeling After Total Knee Arthroplasty: Does Resurfacing the Patella Affect the Ability to Kneel?

    Journal of Arthroplasty · Jul 02 2026 · PubMed

    Patella resurfacing in patients without preoperative patellar osteoarthritis resulted in greater dissatisfaction with kneeling despite equivalent functional outcomes after total knee arthroplasty.

Recent reviews

  1. Nociplastic Pain and Central Sensitization in Hip and Knee Arthroplasty: A Practical Primer for Arthroplasty Surgeons.

    JAAOS Global Research & Reviews · Mar 01 2026 · PubMed

    Nociplastic pain affects over one-third of hip and knee arthritis patients; preoperative identification is critical as these patients experience less pain relief and increased opioid use after arthroplasty.
