Filter by:This study aims to assess the efficacy of virtual reality through the Virtual Reality Rehabilitation System (VRRS) added to conventional rehabilitation versus conventional rehabilitation alone, for improving mobility, balance, and walking assessed by Timed Up and Go after primary Total Hip Arthroplasty.
Functional improvements are reached in patients with primary total hip arthroplasty compared to the pre-operative term however some problems as continued range of motion limitations, loss of joint proprioception sensation, and resulting balance and gait disorders may result in failure of the Four Square Step Test. Therefore, the need for the apply of the Modified Four Square Step Test in individuals with primary THA is necessary. The aim of this study is to evaluate the test-retest reliability, concurrent validity and minimal detectable change of the Modified Four Square Step Test in individuals with primary total hip arthroplasty.
Cementless fixation, with or without screw augmentation, has evolved during the past few decades as the preferred method for acetabular reconstruction. Although major improvements have been recorded with regard to clinical outcomes and survivorship, acetabular component loosening remains among the most common causes of failure and revision. Patient age, poor bone quality and conditions, such as osteonecrosis and dysplasia, have been observed to influence negatively long-term clinical results. Initial stability is fundamental for survivorship of cementless cups. Prerequisites to achieve durable cementless cup fixation are close contact with viable native bone, primary mechanical stability and secondary bone integration. Press-fit techniques provide optimal conditions for bone ingrowth and fixation but research focused on cup material in order to improve primary stability. Pore size, bone-implant apposition, and material properties all influence bone ingrowth and long-term stability. Biological ingrowth surfaces have become a standard prosthetic element in reconstructive hip surgery. A material's properties, three-dimensional architecture, and surface texture all play integral parts in its biological performance. Trabecular metal is an important new biomaterial that has been introduced to enhance the potential of biological ingrowth as well as provide a structural scaffold in cases of severe bone deficit. The continuity between the porous and solid parts has been specifically developed to overcome the limitations of the traditional porous coatings. In fact, the absence of an interface between the trabecular structure and the bulk material provides greater structural solidity and thus higher resistance to detachment and corrosion. Initial clinical applications have focused on bone restoration in tumor and salvage cases and in primary and revision reconstructive cases where the increased biological fixation would be of clinical benefit. However the bone ingrowth potential and mechanical integrity of this material offer exciting options for orthopedic reconstructive surgeons such as difficult THA cases, such as patients with high demands, subjects affected by severe hip conditions (i.e. osteonecrosis, dysplasia) or with extremely poor bone quality. Medacta Mpact 3D Metal cup, is an acetabular cup realized using the EBM (Electron Beam Melting) powder technology; this production method offers a high friction and scratch-fit feel for the initial stability, without the need of any additional coating. Moreover the 3D Metal structure creates a favorable environment for bone thus providing secondary fixation. The aim of this study is to evaluate the long term clinical and radiological performance of MPact 3D Metal acetabular component.
The main objectives of this study are to confirm the long-term safety, performance, and clinical benefits of the G7 Acetabular Shells when used with the Vivacit-E and Longevity HXLPE liners and instrumentation in primary and revision total hip arthroplasty.
To compare the impact of pericapsular nerve group block (PENG) versus the supra-inguinal fascia-iliaca compartment block (SFICB) in postoperative analgesia, opioid sparing and enhanced recovery after surgery of total hip arthroplasty by poster-lateral approach.
Degenerative changes in the hip joint, which are indications for operative treatment, are observed in more than 30% over the age of 50. In most cases, the development of a degenerative process in the hip joint is accompanied by changes in the sacroiliac joint. To improve the quality of life, relieve pain, improve the clinical outcomes of rehabilitation after total hip arthroplasty (THA), an integrated approach to treatment is required. The investigators have developed a technique for intraoperative manual correction of the ileosacral displacement of the sacroiliac joint during THA. This clinical study compares the use of this technique during THA and THA by standard method.
This study will look to determine two different types of physical therapy regimens in patients who undergo anterior total hip replacement. We will compare the results of two groups. The first group, the "Formal Physical Therapy" group, will undergo standard physical therapy following their surgery. They will see a physical therapist in a physical therapy office after their surgery. Here, the therapist will work with the patient to strengthen muscles and improve their walking. The second group, the "Self-directed Physical Therapy" group, will undergo physical therapy in the comfort of their own home using common household items (chairs, steps, etc). These patients will be given a list of exercises and stretches to perform on their own. It is our goal to prove that formal physical therapy is not needed after anterior hip replacements.
The purpose of this study is to determine if continuing fish oil supplementation leads to higher blood loss in patients undergoing total hip arthroplasty (THA). Another purpose is to determine if patients on fish oil have less pain after THA. Fish oil (Omega-3 fatty acid) is commonly used by patients as a natural anti-inflammatory to decrease joint pain from arthritis. Supplements, including fish oil, are typically stopped 1-2 weeks prior to surgery as there is an increased risk of perioperative bleeding. However, there are current methods in joint replacement surgery that decrease the risk of perioperative bleeding. With the risk of excessive bleeding being minimized, fish oil may not need to be stopped prior to surgery and could be continued immediately after surgery. The anti-inflammatory effect of fish oil may also help decrease pain after surgery.
The pain and severe wear of hip joints caused by osteoarthritis, rheumatoid arthritis, avascular necrosis and trauma can be subjected to total hip replacement (THR). A hip implant consists of 4 components: acetabular cup, femoral stem, articular liner and femoral head. As an ideal material for THR, ceramic possesses excellent biocompatibility and stability in the human bodies. Moreover, ceramic-on-ceramic interface is highly wear-resistant, preventing generation of wear particles. With the development of latest fourth-generation ceramic Delta, larger femoral heads can be manufactured to conform to the size of native femoral heads. The rate of some of the complications after THR, such as dislocation, can be significantly reduced. The purpose of the present study is to carry out a clinical follow up for each patient who has received the ceramic-on-ceramic THR in order to understand the clinical outcome. Furthermore, the possible complications, such as dislocation and squeaking, can be determined.
Objective: The main objective of this study is to compare the (early) migration of the cemented BiMobile cup at two year post-surgery between two different cup sizes after standard optimal reaming, and consequently adjusting the cement mantle into circa 2 or 4 mm, in patients with a primary cemented total hip arthroplasty (THA). Additionally, the results of the BiMobile cup will be compared to the Avantage cup, which is placed with a standard cup size, resulting in a cement mantle of approximately 2 mm. Study design: A prospective single centre blinded randomised controlled trial. Study population: All patients who meet the criteria to undergo a cemented THA.
