This study will involve patients who are planned to have hip or knee replacement surgeries. They will undergo a Transthoracic Echocardiogram study (an ultrasound of the heart) to look for a Patent Foramen Ovale (PFO). A PFO is a hole in the heart that everyone is born with and in most cases eventually closes by adulthood. However, it does not always close in all people. The investigators will compare the participants as two groups - those with a PFO, and those without, and look for differences in delirium in their postoperative stay. This will help us look for an association between postoperative delirium and the presence of a PFO.
Preoperative anemia is an independent risk factor for the need for allogeneic transfusion during surgery and increased postoperative morbidity. Treatment of preoperative anemia is recommended. However the type of preoperative anemias in elective hip- and knee surgery has only been sparsely studied. This observational study aims to investigate the incidence and type of anemias prior to elective hip- and knee arthroplasty.
This observational study follows a cohort of patients scheduled for elective hip- or knee surgery but has preoperative anemia and are treated with Intravenous (IV) iron prior to surgery according to a recently introduced standardized treatment protocol at 6 high-volume surgical centres.
The purpose of this study is to evaluate the serum levels (pharmacokinetics) of bupivacaine in a series of patients undergoing simultaneous bilateral total knee arthroplasty with the use of a standardized periarticular injection containing free bupivacaine and liposomal bupivacaine.
Study designed to evaluate the Zip Surgical Skin Closure device versus conventional steel staple placement when utilized for surgical wound closure after bi lateral unicompartmental or bi later total knee replacement.
The purpose of this study is to determine if patients undergoing a Total Knee Arthroplasty who receive a single shot Adductor Canal nerve block and local infiltration will have improved functional outcomes compared to individuals who receive a femoral nerve block and local infiltration during the first 24 hours post surgery.
Polyethylene wear and osteolysis remain a concern with the use of modular, fixed bearing total knee arthroplasty. A variety of highly cross-linked polyethylenes have been introduced to decrease this problem, but there is little data on the results and complications of this polyethylene in posterior-stabilized knee prosthesis. The investigators asked the following questions: (1) Are there any differences in the clinical and radiographic results when a highly cross-lined polyethylene is compared to a standard liner? (2) What is the frequency of reoperation in these two groups and are there any specific complications related to highly cross-linked polyethylene liners.
The success of the Triathlon Tritanium Knee will be determined by comparing the rate of absence of revision for aseptic loosening of the tibial baseplate at 2 years with the rates reported in the literature.
The purpose of this study is to further investigate the efficacy of adductor canal nerve blocks for pain management after total knee replacement. Specifically we are studying adductor canal nerve blocks in conjunction with epidural anesthesia, which is a combination that has not been extensively researched before. Our question is whether combining these modalities will enhance patient satisfaction after surgery and accelerate patients' readiness to discharge.
