Filter by:Rehabilitation after total knee arthroplasty is very important in terms of range of motion of the knee, muscle power, normal gait, pain control and consequently the patient's satisfaction. Convectional rehabilitation methods in assist of therapist required high demand of resources. Recently, outpatient clinic or tele-communication tool based rehabilitations were investigated and reported equivalent results. However, those methods also required group or one-to-one facing that restricted availability of the exercise. With development of the motion tracking technology, new device that gives real time feedback with augmented reality images can be used for rehabilitation in home-based setting. This study aims to compare the clinical outcomes after the rehabilitation by interactive home-based device or conventional inpatient setting.
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 purpose of this study was to identify the major complications and their risk factors of elderly patients who had undergone Hemi-hip Arthroplasty.
The present randomized controlled trial is designed to compare one novel total knee replacement (TKR) design and two conventional TKR designs in terms of functional outcome. 80 patients will be randomized in each of the three arms (240 altogether).
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.
