Preoperative Pain Sensitivity Has a Greater Impact on Clinical Outcomes Than Coronal Alignment Strategy in Robotic-Assisted Total Knee Arthroplasty

Sep 22, 2026

This study aimed to determine whether preoperative pain sensitivity or coronal alignment strategy has a greater impact on patient-reported outcome measures (PROMs) following robotic-assisted total knee arthroplasty (TKA). The findings revealed that preoperative pain sensitivity was a significant negative predictor of PROMs, while the alignment strategy did not influence outcomes, particularly in patients with high pain sensitivity. In contrast, patients with low pain sensitivity experienced better outcomes with functional alignment compared to mechanical alignment.

Patient-Reported Outcomes Measures Collection Method by Timeframe: Different Strategies for Different Times

Sep 22, 2026

The authors aimed to evaluate the collection methods and response rates of patient-reported outcomes measures (PROMs) in a regional arthroplasty registry to identify strategies for improving data collection. Their findings revealed that completion rates for PROMs varied significantly based on patient demographics and the timing of the surveys, with a notable shift towards remote collection methods as time from surgery increased. The study suggests that tailored strategies are necessary to enhance PROMs collection in accordance with CMS standards.

Toward Standardized Reporting in Non-Traumatic Osteonecrosis of the Femoral Head: Recommendations for Clinical Study Design and Reporting

Sep 21, 2026

The authors aim to address the significant inconsistencies in clinical studies of non-traumatic osteonecrosis of the femoral head (ONFH) by proposing a standardized reporting framework. This framework seeks to enhance transparency, reproducibility, and comparability across studies, ultimately improving the quality of evidence regarding disease progression and treatment effectiveness. The authors emphasize the need for consistent application of these reporting standards to facilitate better interpretation and synthesis of ONFH research findings.

Low Back Pain and Depression Are Associated with Worse Patient-Reported Outcomes After Primary Total Knee Arthroplasty

Sep 21, 2026

The authors aimed to determine whether the co-occurrence of low back pain and depression affects patient-reported outcomes following primary total knee arthroplasty (TKA) more than either condition alone. Their analysis of 4,173 patients revealed that both conditions were associated with significant reductions in functional improvement and lower odds of achieving clinically important outcomes, particularly among the lowest-improving patients, suggesting that these factors should be considered in preoperative assessments. The study highlights the importance of using distributional analyses in registry research to better understand patient outcomes.

There Is No One-Size-Fits-All: Surgical Approach Dictates Optimal Bearing Surface Configuration Choice in 30,000 Total Hip Arthroplasties Over 25 Years

Sep 21, 2026

The authors aimed to determine how surgical approach and bearing surface configuration influence the risk of dislocation in total hip arthroplasties (THAs). Their analysis of over 30,000 THAs revealed that the optimal bearing surface choice varies by surgical approach, with dual-mobility constructs reducing dislocation risk in posterior THAs, while flat/neutral polyethylene liners showed the lowest dislocation risk in antero-lateral THAs. The findings suggest that a tailored approach to bearing selection, rather than a uniform strategy, is essential for minimizing dislocation risk in THA.

Area Deprivation Index, Institutional Practice, and Utilization of Neuraxial Anesthesia in Total Knee Arthroplasty

Sep 21, 2026

This study aimed to investigate the relationship between socioeconomic status, as measured by the Area Deprivation Index (ADI), and the utilization of neuraxial anesthesia (NA) in total knee arthroplasty (TKA). The findings revealed that hospital site significantly influenced NA rates, while ADI did not show a meaningful association with anesthesia utilization or postoperative outcomes, suggesting that institutional practices may play a more critical role than socioeconomic factors in this context. The authors recommend further research to explore these dynamics in more diverse populations.

Preoperative Medial Proximal Tibial Angle Does Not Influence Clinical Outcomes Following Mobile-Bearing Unicompartmental Knee Arthroplasty

Sep 21, 2026

This study aimed to determine whether the preoperative medial proximal tibial angle (MPTA) affects clinical outcomes after mobile-bearing medial unicompartmental knee arthroplasty (UKA) in patients with antero-medial osteoarthritis. The findings revealed that preoperative MPTA did not significantly influence clinical outcomes, as measured by the Oxford Knee Score, across different MPTA groups, suggesting that alignment strategies based on MPTA may not be necessary to optimize postoperative results.

Assessment of Acetabular Component Anteversion Following Total Hip Arthroplasty: Current Imaging Techniques and Limitations

Sep 21, 2026

The authors aim to evaluate the various imaging techniques used to measure acetabular component anteversion following total hip arthroplasty (THA) and their respective limitations. They highlight that while radiographs are commonly used for assessing acetabular position, CT scans may offer greater accuracy and reproducibility, particularly when the entire pelvis is imaged. Understanding the strengths and weaknesses of these methods is crucial for addressing complications such as instability and pain after THA.

Comparative Outcomes of Patello-Femoral and Unicompartmental Knee Arthroplasty: A Propensity-Matched Analysis at Two, Five, and 10 Years

Sep 21, 2026

This study aimed to compare the long-term outcomes of patello-femoral arthroplasty (PFA) and unicompartmental knee arthroplasty (UKA) regarding reoperation rates and implant survivorship over two, five, and ten years. The results indicated that while PFA had significantly higher rates of subsequent knee arthroscopy and revision surgery, both procedures demonstrated comparable implant survivorship and conversion rates to total knee arthroplasty. These findings suggest that the increased likelihood of secondary procedures associated with PFA should be a key consideration in surgical decision-making.

Revision Indication Is Associated with Early Mortality After Revision Total Hip Arthroplasty: A Population-Based Study

Sep 21, 2026

The authors aimed to evaluate the 30- and 90-day mortality rates following revision total hip arthroplasty (R-THA) and to identify risk factors associated with early mortality. Their findings indicate that while overall mortality rates are low, patients undergoing R-THA for periprosthetic joint infection (PJI) and periprosthetic fracture (PPFx) experience significantly higher mortality risks compared to those revised for aseptic loosening. Additionally, the study highlights that the extent of the revision procedure does not influence mortality outcomes.
