BackgroundObtaining informed consent is an essential step in the surgical pathway. Providing adequate patient education to enable informed decision making is a continued challenge of contemporary surgical practice. This study investigates whether the use of a patient information website, to augment patient education and informed consent for elective orthopaedic procedures is an effective measure.MethodsA randomised controlled trial was conducted comparing the quality of informed consent provided by a standard discussion with the treating surgeon compared to augmentation of this discussion with an online education resource (www.orthoanswer.org). Participants were recruited from orthopaedic outpatient clinics. Patients undergoing five common orthopaedic procedures were eligible to participate in the trial. The primary outcome measure was knowledge about their operation. Satisfaction with their informed consent and anxiety relating to their operation were the secondary outcome measures.ResultsThere was a statistically significant increase in patient knowledge for the intervention arm as compared to the control arm (p < 0.01). Patients in the intervention arm, had an average score of 69.25% (SD 14.91) correct answers as compared to 47.38% (SD 17.77) in the control arm. Satisfaction was also improved in the intervention arm (p = 0.043). There was no statistically significant difference between the control and intervention arm relating to their anxiety scores (p = 0.195).ConclusionsThe use of a patient education website as an augment to informed consent improves patient knowledge about their planned operation as well as satisfaction with the consent process whilst not increasing their anxiety levels. We recommend that all patients be directed to web based education tools to augment their consent.Trial registrationAustralian New Zealand Clinical Trials Registry (ANZCTR) ACTRN12614001058662.
Patients are commonly using the internet as an information resource, in spite of the highly variable quality of this information. This highlights the need for patient information websites which reflect the current standards of clinical practice.
One of the primary aim of total knee arthroplasty (TKA) is restoration of the mechanical axis of the lower limb. Maintenance of the mechanical axis within 3 degrees of neutral has been shown to result in improved clinical results and implant longevity. The aim of this study was to investigate the efficacy of this robotic-assisted system in coronal plane component positioning in TKA. We also describe the learning curve associated with adoption of this technology. A total of 72 total knee replacements were completed between November 2017 and September 2018 by a single surgeon using the robotic-assisted surgery (RAS) system. Cases were recorded from the time the study surgeon first adopted this technology and represent the “learning curve.” Pre- and postoperative coronal weight-bearing alignments were measured and intraoperative robotic-assisted registration data and duration of use were collected. Of the 72 TKAs in this series, 93.3% were corrected to the desired alignment of within 3 degrees of neutral. The knees that were not corrected to neutral had a mean preoperative alignment of 11.57 degrees of deformity as compared with 4.29 degrees for those that were corrected to neutral. A learning curve effect during adoption of this new technology was not found when analyzing RAS usage time. The RAS system produced accurate coronal alignment in TKA in more than 93% of cases with no learning curve effect. Our study suggests that this system is easily adopted, safe, and accurate.
Scaphoid non-union develops in 10% of scaphoid fractures. There is sparse literature on fixation methods other than screws. We compared union rates following fixation of scaphoid non-union using screw fixation and a novel method of plate fixation. Retrospective study. Union rates were assessed at 3 months post-operatively by a musculoskeletal radiologist. 15 patients underwent screw fixation and 15 underwent plate fixation. 86% union rate with screw fixation and 72% plate fixation united. There was no significant difference. Screw fixation and plate fixation in our institution both provide union rates that are consistent with the literature.
Patients are commonly using the internet as an information resource, in spite of the highly variable quality of this information. They should be encouraged to exercise caution and to utilize only well-known sites.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
