Filter by:Total hip replacement is designed to alleviate pain, reduce disability and improve function and physical activity levels. Whilst pain, disability and function are often measured following surgery, actual physical activity is not. The aim of rehabilitation after total hip replacement would be to obtain optimal strength and range of movement at the hip along with cumulative endurance and balance. It is taken for granted that, once function is restored, the patient returns to physical activity levels associated with good health. In a previous study conducted by the same team it was observed that patients, at the end of 3 months after hip surgery, do not reach the levels of physical activity which are proven to be beneficial for health. Physiotherapy plays an important role in improving function and increasing levels of Physical activity in total hip replacement patients, but there is limited literature to substantiate this claim. There is a need to enhance levels of physical activity in patient after total hip replacement towards levels that are associated with good health. This study aims to demonstrate a method of enhancing physical activity levels after total hip replacement using a pedometer based intervention over a period of 3 months. Patients will follow a customized progressive stepping activity schedule aimed at establishing levels of physical activity that are associated with good health. To fully understand recovery patterns subjective and objective measures of strength of the hip muscles, range of motion at the hip, overall endurance, balance and speed of walking of the patient will be assessed. Questionnaires will be utilized to assess quality of life both before and after total hip surgery. The physical activity levels of the patient will be measured with a physical activity monitor. This study will be completed at the Golden Jubilee National Hospital at Glasgow.
The specific aim is to quantify the stability of the acetabular and femoral components of a revision total hip arthroplasty (THA) in vivo as currently performed at our institution. In this way, the investigators will gain insight into the outcome of the current state of the art of revision arthroplasty surgery. In the past, acetabular and femoral component stability has been measured using radiostereometric analysis (RSA) and when patients having revision total hip operations were compared to patients undergoing primary total hip operations it was possible to determine differences in stability and this was predictive of the intermediate to long-term performance of the acetabular and femoral reconstruction. The investigators propose to use this established, high resolution technique to assess and compare the stability of the revision implants.
Orthopedic surgery is reportedly among the most painful surgical procedures. Surgical damage following major orthopedic surgery often involves a large, deep incision with considerable tissue dissection and muscle, bone, and vascular exposure. Post-operative pain after such surgery is exacerbated on movement or by reflex spasms of the muscles, which may delay mobilization, reduce satisfaction, prolong hospitalization, and possibly increase medical costs. We design a prospective randomized study for postoperative pain control following total hip arthroplasty.
The purpose of this study is to determine if there is a difference in stress shielding and bone resorption of the proximal femur in two anatomical stem total hip designs.
The purpose of this prospective clinical data-collection is to document the performance, clinical outcomes, and wear rates of ArCom® and ArComXL® Polyethylene. The data gathered will be collated and used as a part of Biomet's post-market surveillance system and to provide feedback to designing engineers, support marketing efforts, and answer potential questions from reimbursement agencies. Inclusion/exclusion criteria are identical to those indications and contraindications stated in the FDA approved labeling for the device in 510(k) K926107 and 510(k) K043051. Surgical techniques and patient care are to be standard for the surgeons participating in the protocol.
The specific aim of this proposed study is to conduct a prospective RSA clinical study at Massachusetts General Hospital involving 50 patients receiving primary total hip replacements. All patients will receive the vitamin E treated polyethylene acetabular inserts. Short-term femoral head penetration and long-term steady state wear of the polyethylene will be measured using both RSA and Martell analysis techniques. Stability of the acetabular and femoral components will be measured in all patients using RSA analysis. The stability of the cemented femoral stems will be compared to the stability of the cementless femoral components as well as to historic data in the literature. In addition, all patients will complete a self-administered questionnaire to assess the clinical outcome of the surgery and patient satisfaction.
There are two distinct aims of this study: 1. This prospective study is designed to document the long-term (10-year) radiographic and clinical outcomes of a new type of highly cross-linked polyethylene liner which contains vitamin E as an anti-oxidant, (E-Poly), in a group of primary total hip arthroplasty subjects. The clinical outcome of E-Poly will be compared to a group of subjects receiving Arcom XL polyethylene. 2. This study is also designed to document the long-term (10-year) radiographic and clinical outcomes of a new cementless acetabular component having a titanium porous surface (Regenerex). The clinical outcome of this new FDA cleared device will be compared a group of subjects receiving an acetabular component having a plasma sprayed surface.
