Filter by:A prospective multicentre randomised clinical trial of 250 selected patients with THA, who will be randomly assigned to intervention (IG) or control group (CG). Both will have standard physiotherapy during hospitalisation, IG will additionally learn strength and sensory-motor training exercises. Follow up will be performed with physical tests, maximal voluntary isometric contractions and outcome assessment questionnaires at baseline and 1, 3 and 12 months after surgery.
The hypothesis of this study is that there are people running following a total knee arthroplasty (TKA). The objective is (1) to determine if there are people that ran/run following their TKA and (2), in case (1) is true, to identify some general running parameters such as duration, frequency, perceived barriers for running. Patients with a TKA and a score equal or higher than 9 on the UCLA activity scale at any time between 2 years prior to surgery and at present will be invited to participate in the trial by phone. All these patients will receive the study's information form and questionnaire by post with a pre-stamped envelope to return the documents.The survey was created and piloted internally for this study. There are 21 questions, most of them are "yes or no" and some others open questions to assess parameters such as duration of difficulties faced. The questionnaire is composed of three parts. The first part is interested in the preoperative activity (during the 2 years before surgery), the second part in the postoperative activity (during the 2 years after surgery) and the third part refers to the current practice. For each part, people are asked about specific practice parameters and modalities. Furthermore, we seek to determine whether there was/is a willingness to run following TKA, if patients receive any education/information about it and their personal attitudes towards running with a TKA. The anonymized data will be collected by the main author for subsequent analysis.
The purpose of this study is to assess the effectiveness of a preoperative muscle training program on hip or knee TJA (Total Joint Arthroplasty). It aims to improve hospital discharge readiness and functional capacity in both the short and long-term. One of the key factors affecting recovery after TJA is how well the patient functions before their surgery. Thus, interventions addressing preoperative function are expected to be beneficial.
Approximately 40% of patients undergoing total knee arthroplasty develop acute to moderate post operative pain. Furthermore 20-30% develop chronic post operative pain. The objective of this work is to study the effectiveness and safety of pulsed radiofrequency of the saphenous nerve realized during the pre-operative period of total knee arthroplasty. The study design is a randomized, blinded clinical trial. Patients scheduled for total knee arthroplasty are divided into two groups. The first group procedure consists in pre-operative pulsed radiofrequency under ultrasound guidance of the saphenous nerve and standard postoperative pain management by the pain clinic. The second group receives only the standard postoperative pain management by the pain clinic. Patient follow ups are performed 3 times (after 2 weeks, 2 months and 6 months) within a period of 6 months, evaluating pain severity using the VAS.
The primary aim of this study is to determine the effects of pre-surgery exercise known as Prehabilitation, on functional outcomes for patients following Total Knee Arthroplasty (TKA) surgery. The hypothesis is patients that receive effective pre-surgery prehabilitation will demonstrate improved recovery as measured by the 6-minute walk (6MW) test at one month post surgery.
Reducing the length of stay (LOS) after primary arthroplasty is a relatively new target that arouses the attention of orthopedic surgeons in order to return home early through the fast recovery protocols but this goal is also wanted in public health for the sake of overall decline health spending in public costs.
The aim of the study is to assess blood platelet function and activation in patients undergoing both cement and non cement hip joint total alloplasty. Bone cement is used as a special biomaterial to help fix a hip prosthesis in place but is associated with bone cement implantation syndrome causing such complications as hypotension, cardiac arrhythmias. The pathophysiology of bone cement implantation syndrome is not fully known but one theory supports formation of clots in the bloodstream. This directly would activate platelets but no such study has been performed in humans. As bone reaming could potentially cause platelet activation even without bone cement, the study involves a control group of patients undergoing non cemented joint alloplasty.
Total knee arthroplasty is a frequent surgery in France. It currently represents 70,000 interventions per year. The total knee prosthesis is also called tri-compartmental because it allows articulation between the femur and the tibia but also between the femur and the patella. The patella belongs to the extensor system. It articulates with the femoral trochlea in which it slides. It has an important biomechanical role on the quadriceps strength in addition to allowing flexion-extension movements. In the case of resurfacing, the joint face of the patella is cut off; A convex polyethylene implant is sealed with cement using studs on the same face. In case of non-resurfacing, the surgeon leaves in place the cartilage of the patella which will be in direct contact with the femoral prosthetic trochlea. Both methods have advantages and disadvantages. For some implants, it is recommended to resurface the patella because the implant is not very tolerant with the native patella. Other implants have been designed to be better adapted to the preservation of patellar cartilage. There is currently no evidence that one method is superior to the other on new generation implants known as "patellar friendly". It seems necessary to compare both methods in terms of long-term postsurgery results.
The purpose of this study was to evaluate the efficacy of a one-time, preoperative physical therapy protocol on postoperative (1) discharge disposition, (2) pain, function and stiffness and (3) patient satisfaction.
Total hip replacement (THP) is widely used for hip osteoarthritis treatment. Surgeons are constantly looking to improve all aspects related to this procedure weather is improvement of implant design, instrumentation or surgical technique. Excellent clinical and radiological results were observed at medium and long term in the last years for AMIStem system. This observational study has the objective to survey hip prosthesis stability and function of the operated hip in patients who are not exposed to surgical risks. The principal investigator will contact all patients in order to perform the follow-up visit according to standard practice. Patients operated between January 2010 and December 2011 will be invited in the study during the clinical visit organised according to standard practice. Preoperative clinical and radiological data, intraoperative details and postoperative follow-up data at 1-year will be retrospectively collected. Five-year and ten-year data will be prospectively collected after inclusion in the study.
