Use and Application of Large Language Models for Patient Questions following Total Knee Arthroplasty
A consumer-focused health care model not only allows unprecedented access to information, but equally warrants consideration of the appropriateness of providing accurate patient health information. Nurses play a large role in influencing patient satisfaction following total knee arthroplasty (TKA), but they come at a cost. A specific natural language artificial intelligence (AI) model, ChatGPT (Generative Pretrained Transformer), has accumulated over 100 million users within months of launching.

Social Determinants of Health in Total Joint Arthroplasty: Education
Accurately measuring social determinants of health (SDOH) can be challenging due to the intricate interplay between them. For instance, education level and neighborhood affluence can influence the impact of race or socioeconomic status (SES) on outcomes following lower extremity total joint arthroplasty (TJA) [1-3]. Various proxies, such as insurance statuses, payer types, zip codes, comorbidities, income levels, racial or ethnic categorizations, and education levels, have been used to quantify disparities in outcomes following TJA and serve as individual proxies for socioeconomic status.

Letter to the Editor in Response to “Are 20% of Patients Actually Dissatisfied Following Total Knee Arthroplasty? A Systematic Review of the Literature”
I read DeFrance and Scuderi ’s article titled, “Are 20% of Patients Actually Dissatisfied Following Total Knee Arthroplasty? A Systematic Review of the Literature,” with sincere interest [1]. It is commendable that the authors sought to examine recent literature to arrive at a more accurate current dissatisfaction rate a fter primary total knee arthroplasty (TKA). The systematic review reported an average patient dissatisfaction rate of 10% after these procedures, using the 21 articles selected for final inclusion. (Source: The Journal of Arthroplasty)

Comparing Analgesic Efficacy of Different Regional Blocks After Total Hip Arthroplasty
By conducting a randomized clinical trial of 120 patients who underwent primary total hip arthroplasty (THA), Takeda et  al [1] compared postoperative analgesic efficacy between anterior quadratus lumborum block (AQLB) and femoral nerve block (FNB). They showed that primary outcome; total morphine consumption by the patient-controlled intravenous analgesia pump over the first 24 hours postoperatively, was not signi ficantly different between the 2 blocks. However, the authors did not clearly state if a unified target of postoperative pain control was designed and whether patients were well-instructed to deliver fentanyl ...

The American Association of Hip and Knee Surgeons Adult Reconstruction Fellowship Recognition Initiative: It ’s About Time
Fellowship training in adult reconstruction (AR) began nearly 40 years ago as selected surgeon leaders mentored graduating residents for an additional year of training, primarily using an apprenticeship model. In the years since, the number of AR fellowships and positions has grown substantially, and AR now represents one of the most popular and sought after subspecialty fellowships in orthopedics [1]. In 2023, there were a total of 114 fellowship programs that participated in the match, offering a total of 226 positions. (Source: The Journal of Arthroplasty)

The Frank Stinchfield Award: Assembly and Dissociation Forces Differ Between Commonly Used Dual Mobility Implants: A Biomechanical Study
Intra-prosthetic dissociation (IPD) is a complication unique to dual mobility (DM) implants where the outer polyethylene head dissociates from the inner femoral head. Increasing reports of IPD at the time of closed reduction of large head DM dislocations prompted this biomechanical study evaluating the assembly and dissociation forces of DM heads.

The Association Between Oral Bone Mineral Density –Reducing Medications and the Risk of 2-Year Implant-Related Complications Following Total Knee Arthroplasty
Certain medications interfere with the bone remodeling process and may potentially increase the risk of complications after total knee arthroplasty (TKA). As patients undergoing TKA may be taking these bone mineral density (BMD) –reducing medications, it is unclear as to whether and which medications impact TKA outcomes. Therefore, the purpose of this study was to observe the impact of various BMD-reducing medications on 2-year implant-related complications following TKA. (Source: The Journal of Arthroplasty)
