    Colorado Joint Replacement


    The doctors at Colorado Joint Replacement consider research a cornerstone of their practice. They are involved in both clinical studies with patients to investigate the efficiency and longevity of knee and hip replacements. In addition to clinical research, our team is also working with the engineering departments at both the University of Tennessee and University of Denver to improve both the quality and longevity of total joint replacements.

    The research performed by our doctors helps take the guesswork out of designing new medical devices and allows our doctors to find the most effective method of care, which translates into the latest technology and best care for our patients.

    Traditional Intravenous Fluid vs. Oral Fluid Administration in Primary Total Knee Arthroplasty: A Randomized Trial

    Dr. Jason Jennings was awarded the 2019 James A. Rand, Young Investigator’s Award for his research on fluid administration for patients undergoing a primary total knee replacement.  With the help of his co-author’s, Mauricio Mejia MD, Michael A. Williams MD, Roseann M. Johnson BS, CCRP, Charlie C. Yang MD and Douglas A. Dennis MD, Dr. Jennings and his team set to establish a preoperative fluid protocol for patient prior to their joint replacement. This protocol is now utilized by many surgeons both nationally and internationally. 

    The study enrolled 130 patient and randomized them into either a traditional or oral fluid management group.  The traditional group was asked to stop eating or drinking at midnight the night before the procedure.  The oral group was asked to encourage to drink a minimum of 20 ounces of clear liquids three times a day for three days leading up to their procedure.  Patients in this group also had 10 ounces of clear liquids 4 hours prior to their procedure. After analysis of outcomes, it was found that our oral testing group found short-term benefits with post-operative swelling and body weight fluctuations.


    Home-Health-Care Physical Therapy Improves Early Functional Recovery of Medicare Beneficiaries After Total Knee Arthroplasty

    Dr. Jason Jennings was also recognized with the 2020 Rose Excellence in Research Award at the American Physical Therapy Association from his collaborative efforts with University of Colorado Anschutz Campus Rehabilitation program.  Authors, Jason R FalveyMichael J BadeJeri E ForsterRobert E BurkeJason M JenningsEugene Nuccio and Jennifer E Stevens-Lapsley.

    The primary purpose of this project was to determine if physical therapy can be linked to improvements for patient in home-healthcare setting after a total knee replacement.  This study showed that low home-health-care PT utilization was significantly associated with worse recovery in activities of daily living after total knee arthroplasty for Medicare beneficiaries, after controlling for medical complexity, baseline function, and home-health-care episode duration. Patients who are served by rural agencies or who have higher medical complexity receive fewer PT visits after knee replacement and may need closer monitoring to ensure optimal functional recovery.


    Control-Matched Evaluation of Patellar Crepitus after Total Knee Arthroplasty

    Dr. Douglas A. Dennis authored a study which evaluated the many factors that can cause  grinding (i.e., patellar crepitus) around the kneecap, which results when scar tissue develops around the kneecap after total knee replacement. The findings of this research will prove helpful in lessening the incidence of this problem for future total knee replacement recipients. This research received the prestigious John Insall Award for its authors: Dr. Dennis, and co-authors Raymond H. Kim, MD, Derek R. Johnson, MD, Bryan D. Springer, MD, Thomas K. Fehring, MD, and Adrija Sharma, PhD.

    The evaluation compared a group of patients who developed this problem with a group that did not suffer this condition that was matched for age, gender, and body weight. An extensive analysis of patient history and diagnostics showed there were many factors associated with development of patellar crepitus including implant size and design, a history of previous knee surgery, and thickness of the replaced kneecap, among others.

    Operation Walk Denver

    Colorado Joint Replacement

    Operation Walk Denver

    Operation Walk Denver is a volunteer organization that provides joint replacements to people in developing countries and here at home.

    Operation Walk doctors, physical therapists, nurses, anesthesiologists, and surgery support teams perform dozens of joint replacements on each mission. While there, they also provide education and training to medical staff in these often remote villages, enabling them to treat patients on their own. To make this work possible, however, Operation Walk depends on a community of supporters.

    By supporting the Operation Walk doctors and their teams through a donation, you can help make joint replacement possible for people who could never afford it otherwise. For many of these people, it's more than living without pain-it's usually life changing.
