    Abstract Background: Conversion surgery from unicondylar knee arthroplasty (UKA) to total knee arthroplasty (TKA) remains a challenge due to scarring, implant/cement removal, and loss of bony landmarks. Robotic-assisted (RA) TKA may assist in challenges seen in manual conversion TKA. The aim of this study is to identify if there are differences in components and functional outcomes dependent on manual/RA primary UKA and conversion TKA.
    Methods: A retrospective chart review was performed on patients undergoing conversion from UKA to TKA over a 10-year period at a single institution. Data extracted included surgical technique, reason for UKA failure, range of motion at 1 year, need for augments, and utilization of revision components.
    Results: Forty-nine patients (50 knees) with a UKA converted to a TKA were divided into 4 groups based on primary and conversion surgery: manual-to-manual (n = 11), manual-to-robot (n = 11), robot-to-manual (n = 11), and robot-to-robot (n = 17). There was no difference in need for augments (
    Conclusions: Our study did not show any statistically significant differences of primary RA or manual UKA to RA or manual TKA in terms of range of motion at 1 year, complications, or differences in components. RA conversion from UKA to TKA is a new but equivalent technique to manual conversion. Primary surgery may impact the requirement for augments during conversion surgery.

    Abstract Conversion of patellofemoral arthroplasty to total knee arthroplasty (TKA) has been described as similar to primary TKA, although it may come with more challenges and worse outcomes. With the increased rate of revision following conversion TKA vs primary TKA, robotically assisted TKA provides an alternative technique to manual conversion. We present 3 cases of robot-assisted conversion of prior patellofemoral arthroplasty to TKA with good mechanical and clinical outcomes and no intraoperative complications.

    Abstract Introduction: Experts have called for a comprehensive didactic curriculum in orthopaedic residency training. This study examined the effects of an anatomic-based, integrated conference program on annual Orthopaedic In-Training Examination (OITE) scores at a single orthopaedic residency program.
    Methods: We implemented a new, integrated, anatomic-based curriculum in January 2005. Differences between scores were analyzed by postgraduate year (PGY) of training. OITE scores (percentile ranking and raw scores) of year 1 (PGY-2) through year 4 (PGY-5) residents exposed to the curriculum (2005-2009) were compared to prior PGY-2 through PGY-5 residents (2000-2004) who had experienced the previous unstructured curriculum. To evaluate for cohort effects, United States Medical Licensing Examination (USMLE) Step I scores for these 2 groups were also compared.
    Results: Eight residents were exposed to the new conference program and 8 to the prior conference program. All residents' percentile rankings improved after exposure to the curriculum, although improvement was not statistically significant for all participants. The most dramatic improvements in OITE scores were seen for PGY-4 and PGY-5 residents, which improved from 65th to 91st percentile (P  =  .03) and from 66th to 91st percentile (P  =  .06), respectively. There were no differences between the cohorts in USMLE Step I scores.
    Discussion: Initiation of an integrated, anatomic-based, resident conference program had a positive impact on resident performance on the OITE.
