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.
Mako TKA Short-Term Trial
The total knee replacement procedure is being tested with a new technology involving the robotic assistance in making precision cuts to the bones thereby allowing retention of crucial parts of the knee anatomy. The Makoplasty procedure utilizing the Mako robot is being tested across three sites in the US with a 3 month follow-up on the patients participating in this trial. The new cutting mechanism was designed in part by Dr. Kreuzer and is being tested with FDA approval.
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.
Anterior Hip Resurfacing
The direct anterior approach to Hip Resurfacing is one of the minimally invasive techniques used in hip resurfacing surgery. Continuing orthopedic experience suggests that this procedure may offer several advantages
The MAKOplasty Unicodylar Knee Resurfacing procedure is a FDA approved treatment option for patients who suffer from osteoarthritis damage in the medial (inner) portion of the knee.
Prosthetic Infection Diagnosis Technique Study
Artificial joints (Prostheses) are sometimes infected beyond cure and must be then taken out with another surgery followed by yet another new prosthesis implanted (Revision surgery). Since the signs and symptoms to establish the infection of these prostheses are still not a 100% sure this study seeks to establish the utility of a new form of diagnostic mechanism. With the use of a new compound coupled with radiological imaging techniques a better way of diagnosing these troubling infections may be discovered. Pending the beginning of enrollment in this study.
Comparison of Anterior Approach Hip Replacement with Traditional THA
The direct anterior approach to Hip Replacement is one of the most advanced and difficult minimally invasive techniquesfor Total Hip Arthroplasty (THA). Since Dr. Kreuzer is performing these in patients who have had the other hip replaced in the past with the traditional approach, it provides us a unique opportunity to compare the outcomes of the two kinds of surgeries in the same patient. This study is still in its design phase and we are eagerly awaiting funds to start.
Retrospective Analysis of Bilateral Hip Replacement Whereby One Side Received the Direct Anterior Approach (MRI Study):
The Primary objective of this study is to compare 2 different approaches for hip replacement in patients having undergone bilateral Total Hip Arthroplasty (THA). The study will evaluate the effect of the anterior approach on long term outcomes, functional muscle testing and MRI evaluations.
Retrospective Chart/Radiographic Review of UKA
The primary objective of this study is to evaluate several diagnoses, treatments, and outcomes related to partial osteoarthritis (OA) of the knee mostly on the inside of the knee, also known as unicompartmental OA or UKA.
Comparison of Robotically versus Manually Implanted Knee Replacement
The primary objective of this study is to compare the clinical and radiographic outcomes of Unicondylar Knee Arthroplasty (UKA) also known as partial knee replacement in three patient groups, one undergoing implantation of an UKA under robotic guidance, one undergoing computer navigated Total Knee Arthrop (TKA), and one with traditional manual instrumentation. This study is also dubbed as the Functional Outcomes Study (FOS-Mako). Actively enrolling in this study.
