Active clinical trials for "Osteoarthritis, Hip"

Younger hip patients often need revision of their hip replacement due to wear and loosening. Newer concepts (resurfacing and large head total hip replacement) with articulation surfaces in metal may reduce the wear, increase the longevity of the implant and give an improved function. The possible downside is that these concepts releases metal debris to the body. The investigators wish to see if the newer interventions are a clinical improvement compared to standard. The investigators also wish to investigate the extent of metal released to the body and any effect on the immune system. Finally the investigators wish to investigate the stability of these new implants and their ability to preserve the bone around the implant. The investigators hypothesis is: That the metal on metal articulations will not have better clinical outcomes than standard The resurfacing implant is expected to preserve the bone of the upper femoral bone. The implants are expected to be stabile within the first year.

Osteoarthritis disables approximately 10% of people who are 60 years or older and compromises the quality of life of more than 20 million Americans every year. Osteoarthritis is caused by the breakdown of cartilage that lines the bones at your joints from daily wear and tear and results in pain and restricted function. Total hip arthroplasty (THA) or total hip replacement, is currently one of the most successful and cost-effective treatments used to eliminate pain and restore function in those suffering from osteoarthritis. There are multiple ways to perform a THA. The main difference between each type is the point of incision in relation to a muscle on the outer surface of your hip bone: gluteus medius. The incision performed can be anterior (in front of the muscle), anterolateral (in front and to the side of the muscle), or posterior (from the back). Each of these approaches has its own advantages and disadvantages, but there is no evidence available that makes one better than the other. The purpose of this study is to determine which of the three approaches to THA is the most effective. The main outcome that will determine the most effective approach is the functional ability of the patients included in this study at 52 weeks. The investigators will also compare whether the patient's: length of hospital stay, use of assistive devices, need for revision surgery, ability to return to work, ability to relieve pain, complication rate, and quality of life. The investigators hypothesize that the anterior approach will be the most effective approach in reducing the rate of post-operative complications after THA.

Total hip arthroplasty is a method of choice for treating advanced osteoarthritis of the hip and one of the most frequent orthopedic procedures. Of all hip surgical approaches described, the tendency for minimally invasive techniques has been dominated over the last few years due to faster patient mobilization, reduced postoperative pain and need for blood transfusion. Two of the most common approaches used for minimally invasive total hip arthroplasty are: AMIS anterior approach and mini-posterior approach, which is a modification of the standard posterior approach. The purpose of this study is the biochemical, imaging and clinical evaluation of the tissue damage caused by the above-mentioned techniques of minimally invasive total hip arthroplasty.

The objective of the present study is to determine the impact of intraoperative IV-iron supplementation on postoperative recovery of RBC mass by retrospectively analyzing and comparing the changes of postoperative hematocrit values after the surgery in patients underwent elective uni-limb total knee arthroplasty surgery with or without IV-iron supplementation during surgery

This prospective study compares an oral direct factor Xa inhibitor with LMWH for thromboprophylaxis in the patients undergoing THA.

The aim of this study is to evaluate periprosthetic bone mineral density (BMD) changes in the proximal femur after implantation of the Fitmore compared to the CLS stem.

This is a prospective, three-arm, comparative study with a provider-crossover design. The first arm will comprise the standard of care pain regimen after discharge, which comprises PRN oxycodone, tramadol, and acetaminophen. The second arm will comprise a multimodal pain regimen; however, patients will still be routinely provided PRN oxycodone and tramadol to use on an as needed basis. The third arm will comprise a multimodal pain management protocol, which does not routinely allow for opioid consumption. However, patients will be provided a one week supply of oxycodone and tramadol for emergency pain relief only.

We propose to evaluate a preoperative education of the patient and a new surgical technique (the mini-invasive THR) that could reduce the time to achieve functional independence. The primary objective of the trial is to assess the time to reach functional independence after total hip replacement depending on the treatment groups: preoperative education versus no preoperative education and mini-invasive procedure versus standard procedure. The study hypothesis is that education and mini-invasive procedure will reduce the time to reach functional independence. This is a prospective trial with a double randomization.

Total hip arthroplasty (THA) has been successful in relieving pain and restoring function in patients with advanced arthritis of the hip joint. Increased focus on earlier recovery and decreased postoperative pain has improved overall satisfaction. However, there is still a gap between the clinical scores in objective surveys and patient satisfaction. Direct anterior approach total hip arthroplasty has a low dislocation rate, abductor strength restoration, acceleration, and cosmetic advantages. In this method, capsulotomy with repair or capsulectomy is applied as the preferences of surgeons. Therefore, this can cause both a decrease in hip flexion strength and a loss in knee extension strength. Our aim in this study is to reveal how much muscle loss was caused by comparing both methods with the intact side.

This Prospective, Single-center, Pilot Study will assist in gaining an understanding of the actual CRFA lesions in an in vivo situation in areas where CRFA is utilized as a standard of care treatment option for the relief of chronic pain (cervical facet joints, thoracic facet joints, lumbar facet joints, Sacroiliac (SI) region, hip and knee).
