Current trends in retraction of plastic surgery and reconstruction research.

BACKGROUND: Various studies regarding retractions of publications have determined the rate of retraction has increased in recent years. Although this trend may apply to any field, there is a paucity of literature exploring the publication of erroneous studies within plastic and reconstructive surgery. The present study aims to identify trends in frequency and reasons for retraction of plastic and reconstructive surgery studies, with analysis of subspecialty and journals. METHODS: A database search was conducted for retracted papers within plastic and reconstructive surgery. The initial search yielded 2347 results, which were analyzed by two independent reviewers. 77 studies were jointly identified for data collection. RESULTS: The most common reasons for retractions were duplication (n = 20, 25.9 %), request of author (n = 15, 19.5 %), plagiarism (n = 9, 11.6 %), error (n = 9, 11.6 %), fraud (n = 2, 2.6 %), and conflict of interest (n = 1, 1.3 %). 15 were basic science studies (19.4 %), 58 were clinical science studies (75.3 %), and 4 were not categorized (5.2 %). Subspecialties of retracted papers were maxillofacial (n = 29, 37.7 %), reconstructive (n = 17, 22.0 %), wound healing (n = 8, 10.4 %), burn (n = 6, 7.8 %), esthetics (n = 5, 6.5 %), breast (n = 3, 3.9 %), and trauma (n = 1, 1.3 %). Mean impact factor was 2.9 and average time from publication to retraction was 32 months. CONCLUSION: Analysis of retracted plastic surgery studies revealed a recent rise in frequency of retractions, spanning a wide spectrum of journals and subspecialties.

Utilization of patient reported outcomes measurement information system in plastic and reconstructive surgery research.

BACKGROUND: The patient-reported outcomes measurement information system (PROMIS) was developed by investigators funded by the National Institutes of Health as a standardized means of directly assessing the patients' perspectives across domains. PROMIS domains include physical function, pain, fatigue, emotional distress, and social health. Various studies have reported increased utilization of PROMIS in research articles in specific specialties; however, the extent to which PROMIS has been employed in the field of plastic and reconstructive surgery remains unclear. The goal of the present study was to characterize the prevalence and trends of PROMIS within plastic and reconstructive surgery articles. METHODS: Literature search was conducted across multiple databases for PROMIS studies within plastic surgery literature. We identified 136 articles and the following data were extracted: author name, journal, impact factor, country of origin, year of publication, publication type, subspecialty, study size, and PROMIS measures used. RESULTS: In this study, 136 studies met the inclusion criteria. There was an overall increasing trend in the number of PROMIS studies published. The most common subspecialties that used PROMIS measures were general reconstruction (n = 24), hand (n = 9), and burn (n = 5). The most used PROMIS measures were the pain interference (n = 26), pain intensity (n = 15), and depression (n = 13). A total of 24 journals included PROMIS studies with a mean impact factor of 3.73 (SD = 3.2). The most common country of origin was the United States (n = 42). CONCLUSION: The data demonstrated an increasing use of PROMIS within plastic surgery across a wide variety of subspecialities and study designs. The characterization of these trends allows researchers and clinicians alike to gain a greater understanding of this powerful tool in measuring patient care.

Transition to Robotic Total Knee Arthroplasty With Kinematic Alignment is Associated With a Short Learning Curve and Similar Acute-Period Functional Recoveries.

Background Robotic instruments are increasingly being used in total knee arthroplasty (TKA). The adoption of robotics has allowed surgeons a new level of precision and facilitated the adoption of a kinematic approach in TKA. We sought to examine one surgeon's transition from a traditional mechanical alignment technique to a modified kinematic approach by comparing short-term recovery outcomes of robotic TKA patients with those who underwent traditionally instrumented TKAs. Methodology We examined six-week and six-month postoperative data from 99 traditionally instrumented, mechanically aligned and 66 kinematically aligned robotic TKA patients between January 2021-October 2021 and October 2021-April 2022, respectively. Robotic surgery was performed with VELYS™ (DePuy Synthes, Warsaw, IN, USA) a semi-active, imageless, table-affixed, robotic TKA solution. Results Robotic and traditionally instrumented TKAs did not differ significantly in any functional outcome measures examined, including pain scores, use of assistive devices, or range of motion at six weeks postoperatively. Robotic TKA patients had a better range of motion in knee flexion than traditional TKA patients at six months postoperatively. There were no differences in surgical complications or rates of manipulation under anesthesia within one year postoperatively. Robotic surgery tourniquet times exhibited a steep drop off and equaled traditional methods after only two robotic surgeries were performed. Conclusions Transition to a kinematic, semi-active, robotic TKA demonstrated encouraging results by demonstrating acute-period recovery of function consistent with the current standard of care, as well as a better range of motion at six months postoperatively. The learning curve of this new-to-market device was shorter than previous research on the transition to robotic TKA. Clear advantages of transitioning to robotic instrumentation by any specific functional measure are yet to be elucidated. Further randomized trials are necessary to characterize long-term outcomes.
