Active clinical trials for "Osteoarthritis, Hip"

This study will investigate the ability of systemic dexamethasone to prolong the sensory block duration for lumbar plexus nerve blockade.

The proposed study is a double-blinded randomized controlled trial comparing patient specific instruments with solely standardized instruments and pre-operative planning used for the placement of the acetabular cup prosthesis used in total hip arthroplasty. The investigators will enroll 36 patients who have consented to total hip arthroplasty for treatment of hip pathology. This treatment is a standard of care. Patients will receive standard of care pre- and post-operative care and placement of standard of care implants all of which are commercially available and FDA approved for general use for the clinical indications used in these patients. All patients will receive a pre-operative CT scan for surgical planning and comparison with post-operative CT scan. The difference in intervention between the groups will be the creation and use of patient specific instruments from the pre-operative planning session. These instruments will be used for placement of an indexing peripheral guide wire to direct acetabular preparation and placement of the shell assisting standard surgical instruments. Print-offs from the pre-operative plan will also be used in the treatment group. The post-operative scan will be performed within two weeks of the surgery for both the treatment and control groups. The investigators will analyze the difference in acetabular shell placement (acetabular version and abduction angle) from the pre-operatively planned CT scan. These differences will be compared between the control and experimental groups.

This is a prospective, randomized study comparing two different bone preparation techniques for insertion of a porous coated titanium cementless femoral stem. Patients receiving a bilateral total hip replacement are randomized to conventional broaching on one side and compaction on the other side. Hypothesis: Compaction results in significantly less stem migration [evaluated by radiostereometric analysis (RSA)], less peri-prosthetic bone mineral density (BMD) loss [evaluated by dual energy x-ray absorptiometry (DEXA)], and a higher Harris hip score after two years.

Thr purpose of this study is to compare the clinical and radiological results, as well as the femur bone density measurements of two uncemented total hip prostheses during 5 years of follow up.

The aim of the present study is to explore the most efficient surgical approach in total hip replacement in short and long term when concerning strength, functionality and postoperative complications. The objective is to register muscular strength, hip joint functionality/mobilisation and complications after total hip arthroplasty (THA) performed by two minimal invasive/incision surgeries (MIS) versus the traditionally lateral approach. The primary working hypothesis is that due to a minimal dissection and reduced trauma in the muscles, patients will tolerate early hospital discharge better after MIS than after traditional lateral surgery. Patients in the MIS group will also be more active and maintain muscular strength and hip joint functionality/mobilisation better than patients in the lateral group.

This research is being done to see if there is a difference between two different spinal anesthetics (Mepivacaine vs. Bupivacaine) as it relates to reducing post-operative complications and the time it takes for subjects to regain mobility after surgery.

To determine whether "continuous use" of celecoxib over a 6-month period is more efficacious than "usual or intermittent use" in preventing spontaneous osteoarthritis flares of the knee and hip.

A prospective randomized study comparing accuracy and precision of acetabular component placement in total hip arthroplasty with use of novel electromagnetic navigation system versus freehand technique.

This Trial will obtain clinical data to support an expanded indication for a single injection of Cingal® used for the symptomatic relief of osteoarthritis in the hip joint.

The purpose of this study is to evaluate how older adults might benefit from sessions that teach behavioral coping skills for increasing physical activity and reducing interference from arthritis pain. This study will randomize individuals to receive Engage-PA, or continue to receive treatment as usual. Engage-PA involves two sessions (about 45 minutes each) with a study therapist that teaches individuals behavioral skills for increasing daily steps. These behavioral skills include identifying their personal values and instructions on how to pace their daily physical activity to avoid creating severe pain when walking. All participants in the study will wear small devices that track physical activity such as daily steps throughout the study, which also allow participants to see their daily step counts and overall level of activity. All participants will answer a set of questions about how much arthritis gets the way of many important life activities, their success at living in line with their personal values, and how much thoughts, feelings and body sensations get in the way of living a satisfying life. These questions will be asked at the beginning of the study and 6 weeks into the study.
