  • Robot-assisted Total Hip Arthroplasty After Chiari Pelvic Osteotomy: A Case Report
    In this paper, published in fall of 2016 in the journal "Reconstructive Review", we present the case of a young patient suffering from severe hip dysplasia, and how precise preoperative planning of hip replacement using robot-assisted technology helped to improve the patient's condition dramatically. The full published paper can be downloaded here.

  • Comparison of Functional Outcomes of Total Knee Arthroplasty Using Two Different Single Radius Implants
    In this study, published in the journal “Reconstructive Review”, we evaluated the use of a specific knee replacement implant design in comparison to an alternative model based on patient reported outcomes. The full published paper can be downloaded here.

  • Effects of obesity on the outcome of total knee Arthroplasty
    It is well known that obesity has numerous effects on physical processes within the body. In this current study, we are evaluating the potentially significant effects of obesity on the outcomes of total knee replacement surgery.

  • Comparison of a conventional stem design versus neck-preserving design in hip Arthroplasty
    In this ongoing study, we are evaluating patient reported outcomes from hip arthroplasty using a traditional hip implant stem design versus a newer, neck-preserving implant design

  • Interactions between patient expectations related to hip replacement surgery and actual outcomes
    In this currently ongoing study, we are investigating the complex interactions between patient expectations regarding their upcoming hip arthroplasty and actual (patient reported) outcomes. Here, we are seeking to evaluate the predictability of hip surgery outcomes and to investigate potential confounding factors.

  • Comparison of patient-reported outcome from neck-preserving, short-stem arthroplasty and resurfacing arthroplasty in younger osteoarthritis patients
    Hip resurfacing has been considered a good treatment option for younger, active osteoarthritis patients. However, there are several identified issues related to this technique. In this study, published in the journal "Advances in Orthopedics", we compared clinical outcomes from hip resurfacing with an alternative, i.e. neck preserving arthroplasty. The full published paper can be downloaded here.

  • Computed Tomography Analysis of Postsurgery Femoral Component Rotation Based on a Force Sensing Device Method versus Hypothetical Rotational Alignment Based on Anatomical Landmark Methods: A Pilot Study
    In this study, published in the journal "Advances in Orthopedics", we investigated different techniques to establish accurate rotational alignment during total knee replacement surgery. For this, we compared force sensing based femoral component rotation with traditional anatomic landmark methods. The full published paper can be downloaded here.

  • Clinical Joint Registry
    The joint registry is a collection of data on individuals who have had joint disease including follow up and evaluation of response to therapy. The purpose of the joint registry is to establish a comprehensive patient database to collect and store clinical data associated with use of implantable joint devices to permit quantitative evaluation and qualitative assessment of factors impacting health outcome.

  • A patient-specific Predictive Model Increases Preoperative Templating Accuracy in Hip Arthroplasty
    Application of digital radiography during preoperative templating has shown potential to reduce complications in total hip arthroplasty. In this study, which was published in the "Journal of Arthroplasty", we aimed to further improve digital templating by using a predictive model built on patients' specific data. The model was significant in improving the accuracy of templating within±1 size of the acetabular component. An abstract for the paper can be found here.

  • Bi-Unicompartmental, Robot-Assisted Knee Arthroplasty
    Robot-assisted surgery has had a significant effect on modern arthroplasty in the United States. In this article, published in the journal “Operative Techniques in Orthopaedics”, we discuss the current state of robotic assisted arthroplasty and the valuable combination with novel implant designs that are bone sparing support retention of cruciate ligaments. An abstract for the article can be found here.

  • Osteoarthritis and joint replacement treatment: Effects on gait motor control and walking patterns
    In this ongoing collaboration with the University of Houston and the Center for Neuromotor and Biomechanics Research (CNBR) we are investigating the effects of osteoarthritis on gait control and kinematics in patients in comparison to healthy individuals, and biomechanical changes after arthroplasty treatment.

  • Ceramic-on-Ceramic Hip Implant Study
    Traditional Hip replacements are done with long stem implants, but the newer implants have a short stem thereby giving certain advantages for longevity and handling future complications. One of the problems with the newer younger patients is the life of the implant itself. The materials used to make the artificial joints (implants) are getting better and more durable. The latest is a ceramic which is better when it comes to wear-and-tear of the implant. The surfaces of the implant that are constantly in contact with hip motion are better handled with this material. Thus theoretically this implant is a longer lasting implant. The FDA has approved a clinical trial across the US for many surgeons to test this newest implant by Corin USA. Dr. Kreuzer is one of the lead surgeons in the nation currently following up patients with this implant. The patients were implanted while enrolling in the study from 2012 to early 2014. The follow up can last for multiple years depending on the status of enrollment throughout the nation.
