Filter by:This is a research study to determine if the concentration of local anesthetic through a catheter next to the nerves that go to the hip that is undergoing surgery, affects muscle strength and sense of touch experienced after surgery. This study is looking at the varying concentrations of local anesthetic placed through the catheter.
Patients over 70 years of age, scheduled for joint replacement surgery will be randomized to tramacet/ naloxone plus morphine PCA or to morphine PCA to assess quality of analgesia in the postoperative period. The primary objective is to determine opioid use during combined use of oral tramacet and naloxone infusion perioperatively in elderly patients (70 yrs and older) having elective knee/ hip arthroplasty under spinal anesthesia. Secondary objectives are to determine the incidence VAS scores ≥4 and adverse effects such as nausea, vomiting, sedation, respiratory depression, pruritus, confusion, and time of independent mobilization. Hypothesis: Perioperative naloxone infusion and tramacet provides adequate analgesia in elderly patients undergoing total knee/hip arthroplasty and is associated with 80% reduction in opioid use and reduced opioid-induced side effects.
All patients over 18 who undergo a revision of hip or knee arthroplasty will be included. Patients undergo a CT of the hip joint. A radiologist will mark the presence of cysts and bone loss and will assess implant stability. After the surgery, the surgeon will fill a similar form.
The purpose of this study is to determine if there is a difference in terms of length of hospital stay and post-operative outcomes between patients whose total hip replacement surgery is performed with a minimally invasive versus standard surgical approach.
This study compares two different hip stem components. Both hip stems used in this study allow the femur bone to attach and grow into them for stability. The main difference between the two stems is that one of the stems, the Solution® Stem, is made from Cobalt Chrome, a type of metal, and does not have a hydroxylapatite (HA) coating, while the second stem included in the study, the Restoration hip stem, is made from titanium alloy, a different type of metal that has a roughened surface and allows for a hydroxylapatite (HA) coating to be applied to the entire length of the stem. The HA coating is a thin calcium phosphate layer on the stem to encourage the bone to grow into it. We are trying to see if there is any difference in the initial bony ingrowth between the two stems and to compare the results in patients over the first two years after the surgery and then again at the five-year period.
Patients over 65 years do not have a self care ability the surgery benefits them. The aim of this study is development of a rehabilitation program based on patients' self-rated health. 1. A cross section study including 600 patients 2. RCT including 160 patients
