Filter by:Total knee arthroplasty is a procedure that relieves pain in patients with severe symptomatic osteoarthritis, but it can be associated with postoperative pain, which hinders recovery. In the previous study, we reported evidence of increased pain in patients undergoing staged total knee arthroplasty, in whom the second operated knee had greater sensitivity (tertiary hyperalgesia) as a result of the surgical injury to the first operated knee. Magnesium sulfate is an effective analgesic adjuvant for postoperative pain. Its analgesic property seems to be associated with the regulation of calcium influx into the cells, or antagonism of N-methyl-D-aspartate receptors in the central nervous system. Additionally, magnesium is known to have an anti-inflammatory effect. Inflammatory state may accompany with pain via peripheral or central sensitization. Recently, we reported that magnesium sulfate effectively attenuates not only postoperative pain but also increased pain intensity without serious adverse effects in the bilateral staged total knee arthroplasty. However, the exact mechanism regarding these effects of magnesium sulfate remains unclear. In the present study, we will investigate the analgesic mechanism of magnesium sulfate via analysis of endocrine neurosteroid levels in patients undergoing bilateral staged total knee arthroplasty.
Mobilization and rehabilitation are essential components of a successful functional recovery following total hip and knee arthroplasties. Currently, we have no good measure of how mobile patients are after their surgery. Recent technological advances in personal activity monitors, such as the Fitbit, might provide medical providers and patients the opportunity to more objectively monitor their postoperative mobility and recovery course. However, these consumer activity monitors have yet to be validated in terms of their accuracy and utility for monitoring mobility in the immediate postoperative setting in arthroplasty patients. Our goal is to validate one of the most popular consumer activity monitors, the Fitbit Zip, in the postoperative total joint arthroplasty patient population.
Fast-track total knee arthroplasty (TKA) is a well-established concept including optimized logistics and evidence-based treatment, focusing on minimizing surgical stress and improved post-operative recovery. The aim of this protocol is to compare the standard care and fast track total knee arthroplasties in terms of functional and subjective outcomes, hospital staying, number of transfusions and analgesic consumption.
NAOBE is a randomized, open and prospective clinical trial that evaluates the accuracy to achieve an adequate mechanical axis of the lower extremity in obese patients after total knee replacement.
Various studies have shown that the risk of suffering a urinary retention after knee or hip prosthesis surgery is 10-80%. The aim of the study is to reduce this riks. For this purpose, it is investigated whether a previously known drug (tamsulosin) which is used in bladder emptying disorders, can achieve a reduction in urinary retention after surgery. After the patients agree to participate in the study, they are examined in our urological clinic. Uroflowmetry is performed with sonographic residual volume measurement and prostate volume measurement. Furthermore, a standardized Voiding questionaire (IPSS) is completed. This study is conducted as a double-blind study using a placebo control group. The drug / placebo is taken once a day, five days before and two days after surgery. Subsequently, it is observed whether it comes to a urinary retention or not. After the operation, no further urological checks are planned or needed.
This study aims to compare the postoperative clinical outcomes of Infrapatellar Fat Pad (IPFP) preservation versus resection after total knee arthroplasty (TKA) in patients with knee osteoarthritis. Participants will be identified as normal IPFP or abnormal IPFP based on MRI findings before randomization. The primary outcome is the summed score of Knee Injury and Osteoarthritis Outcome Score (KOOS) covering pain, symptoms, activities of daily life, sport & recreation, knee-related quality of life, and KOOS subscale assessing activities of daily life, sport & recreation. The secondary endpoints will be included: KOOS subscales (pain, symptoms and quality of life), Knee Society Score (KSS), 100 mm Visual Analogue Scale (VAS) Pain, timed up-and-go test, depression, patellar tendon shortening, 100 mm VAS self-reported efficacy of reduced pain and increased quality of life. Adverse events will be recorded. Primary and secondary outcomes will be evaluated or reported blindly at baseline and at postoperative 3 months, 6 months, and 1 year. Intention-to-treat analyses will be used.
The Antibiotic Prophylaxis in Patients Undergoing Elective Total Knee Arthroplasty (TKA): Multi-Center Trial is a study that will compare the effectiveness of various perioperative strategies for antibiotic delivery as prophylaxis for periprosthetic joint infections (PJI) and surgical site infection in elective primary TKA. The investigators hypothesize that a single dose of prophylactic antibiotic administered within 60 minutes before the incision is not an effective way to prevent PJI in elective primary total knee arthroplasty (TKA). The investigators also hypothesize that the prolonged delivery (24 hours) of antibiotic prophylaxis after surgery does not further reduce the incidence of PJI in elective primary TKA. Duke University is the only site recruiting both primary total knee arthroplasty and unilateral knee arthroplasty.
The regime in the aftercare after total hip and knee arthroplasty(THA/TKA) differs a lot between orthopedic surgeons concerning weight bearing. The type of implant and the way of implants' anchoring are considered. In the literature there is no data so far about the way patient take care of the recommended weight bearing during the first 6 weeks after THA and TKA. Over a one year period starting August 2010 all patients undergoing TKA or THA at the investigators institution will have a technical device in their shoes (sole) to measure the load in each step they do in these shoes during the first 6 weeks. Patients are asked to fill out a standardised pain protocol every day (VAS) and document need of pain medication. The investigators recommend 20kg of weight on the operated leg for 6 weeks and full weight bearing at the end of week six. The investigators believe that patients will adjust weight bearing to their level of pain and not to their surgeons recommendations.
