Filter by:This study will evaluate a midterm clinical and radiologic outcome patients who undergo new alumina-zirconia composite ceramic bearing THA.
The purpose of this study is to evaluate the efficacy and safety of various doses of YM150 (the experimental drug) compared to enoxaparin in the prevention of venous thromboembolism in patients that are undergoing elective hip replacement surgery.
The study is a prospective, controlled, randomised and assessor blind study that investigate if the need for bank blood transfusion could be reduced in patients, undergoing primary or revision total hip replacement surgery, who receive their own blood back with the medical device Sangvia. A comparison in need for bank blood will be made between patients that either receive their own blood back or not.
Rehabilitation plays an important part after total hip arthroplasty. In this common practice few studies have been performed on this issue. The aims of this study were: 1. to examine the immediate effects of a walking skill training program on walking, stair climbing, balance, self-reported physical functioning physical functioning, pain and self-efficacy compared to a control group without supervised physiotherapy 2. to examine whether the effects persisted 12 months after surgery
Ketamine (an analgesic drug often associated with morphine in the treatment of Opioid Induced Hyperalgesia) is often mixed in Morphine PCA syringe. We make the hypothesis that ketamine administrated separately via a continuous infusion, could induced a better analgesic effect. We will perform a randomised double blind study to determine the best infusion mode of intravenous ketamine, associated with morphine in PCA syringe or alone in continuous infusion.
Skin preparation solutions are used to clean the skin of the patient before surgery to decrease the rate of infection. This is particularly important for hip replacement to reduce the risk of prosthetic joint infection. The use of a mark on the skin for site identification has become the standard of care to decrease wrong site surgery. The Joint Commission has mandated site identification as part of the surgical "time-out". This procedure is also mandated by hospital policy. Preliminary work on cadaveric skin shows that the type of skin preparation can erase the mark used for surgical site identification. Erasure of the mark presents the surgeon with difficulty in performing the site identification. Any error or lack of visualization of the site marking could lead to catastrophic wrong site surgery. The investigators hypothesis is that chlorhexidine based skin preparation solutions erase site marking in comparison to iodine based skin preparation solutions. The investigators intend to prospectively study twenty patients undergoing total hip arthroplasty. Patients will be randomized to either a chlorhexidine based or an iodine based skin preparation solution. These solutions are both the current gold standard of clinical care. No differences have been shown in infection rates for total hip arthroplasty between these solutions. The site marking will be performed by the same surgeon in a standardized manner. The site marking will include the surgeon's three initials as per usual routine. Underneath the initials three random initials will be placed with a horizontal line drawn underneath. The preparation of the skin will be performed according to the manufacturer's specifications. Digital photographs will be taken of the skin marking after skin preparation. Photographs of the three random initials will be de-identified and placed in a "Powerpoint" presentation form. Ten orthopaedic surgeons will then read the site markings to identify the random initials and to tell whether the mark looks appropriate to perform a surgical timeout. The horizontal line will be digitally analyzed using Adobe Photoshop to quantitatively measure blackness of the mark.
The purpose of this study is to evaluate a hip implant system used when a previous hip replacement surgery has failed.
Total hip replacement surgery is considered to be a very successful surgical procedure for the treatment of degenerative joint disease. The purpose of the study is to evaluate a large size (36mm, 40mm or 44mm) femoral (hip) head called the LFIT™ Anatomic CoCr Femoral Head (Low Friction Ion Treatment). The large size femoral heads will be used with the Trident® X3® polyethylene (plastic) inserts and will be compared with a historical control. Study Hypothesis: The linear wear rate for hips implanted with the LFIT™ Anatomic CoCr Femoral Head is no worse than 0.08 mm wear per year at 5 years post-surgery.
We will compare the effectiveness of Quixil and Tranexamic acid in reducing bleeding during hip and knee joint replacements.
The purpose of this study is to determine if tranexamic acid significantly reduces blood loss and blood transfusion in revision total hip replacement. Tranexamic acid is a drug that helps to reduce blood loss during surgery. Revision total hip replacement surgery is treatment for patients who have previously had hipe replacement surgery which failed and must be repaired/replaced.
