Filter by:The objectives of this study are four-fold: 1. To determine the three-dimensional, in vivo kinematics for subjects having either a fixed- or mobile-bearing Press Fit Condylar (PFC) Sigma Total Condylar III Prosthesis, comparing the in vivo kinematics to determine if one implant type leads to a benefit for the patient. 2. To determine if bearing mobility occurs in PFC Sigma Rotating Platform Total Condylar III Prosthesis under in vivo, weight-bearing conditions during multiple activities (gait, stair descent, deep knee bend and chair rise). 3. To determine if there is a correlation between in vivo kinematic data obtained using fluoroscopy, electromyography (EMG) and ground reaction force (GRF) data and determine if variability occurs between these two TKA types. 4. To determine if a clinical benefit is either visibly detected (video camera) or quantifiably determined (questionnaire) for either TKA type.
The objective of this study is to assess the efficacy of Adductor-Canal-Blockade on pain and morphine consumption after total knee arthroplasty. Our hypothesis is that the Adductor -Canal-Blockade is superior to placebo in reducing pain and morphine consumption after total knee arthroplasty.
The purpose of this study is to determine whether Adductor-Canal-Blockade is effective at reducing pain and morphine consumption after revision knee arthroplasty.
The objectives of this study are to assess the safety and effectiveness of the Journey Deuce Bicompartmental Knee System at 4-6 weeks, 4 months, 1 year, and 2 years when compared to total knee replacement using the Genesis II Total Knee System. The hypothesis is that the Journey Deuce Bicompartmental Knee System is as safe and effective as the Genesis II Total Knee System at the 2-year. The null hypothesis is that there is no difference between the groups.
The use of Aquamantys during total knee arthroplasty will reduce drain output and the necessity for blood transfusions.
Patients undergoing total knee arthroscopy (knee replacement) surgery usually receive a femoral nerve block as part of their anesthetic care. Some centers administer the block with a single shot of local anesthetic, which wears off several hours after surgery. Other centers administer the block with a single shot followed by continuous infusion of local anesthetic, typically for 2 to 5 days after surgery. The latter method, though good for pain control, may result in decreased mobility (while the anesthetic is still active), longer hospital stays, and greater risk of falls. This study will see if using a lower concentration of local anesthetic for the continuous femoral nerve block or only the initial single-shot dose will result in increased mobility and shorter hospital stays.
Prospectively monitor the patients receiving the Oxford Partial knee arthroplasty
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.
