Filter by:For the first time, it is planned to create algorithms for working with a robotic system at different patient flow rates, optimize the use of computed tomography to assess bone density and pronounced osteophytes, develop an algorithm and tactics for treating bilateral osteoarthrosis of the knee joint using an active robotic system. Aim: optimization of total knee arthroplasty using robotic systems and improvement of treatment outcomes. Objectives: to develop algorithms for preoperative planning, surgical intervention using an active robotic system; to improve the technique of active robotic total knee arthroplasty in osteoporosis, osteosclerosis and pronounced osteophytes; to develop a tactic for the treatment of patients with bilateral osteoarthrosis of the knee joint using an active robotic system. It is planned to conduct an open-label retrospective and prospective clinical study in parallel observations.The study is planned to include 250 patients with osteoarthritis of the knee joint stage 3-4 (according to Kellgren-Lawrence). The methodology developed and improved in the dissertation will be introduced into the work of the clinical Departments of Traumatology, Orthopedics and Disaster Surgery, studying the learning curve.
The goal of this randomized clinical trial is to investigate the postoperative recovery following hip and knee arthroplasty procedures depending on the use of either spinal anaesthesia (SA) or general anaesthesia (GA). The main questions are: - Are more patients able to be safely mobilized within 6 hours postoperatively when using GA compared to SA? - Does postoperative pain, nausea and vomiting, dizzyness, occurence of delirium and urinary retention differ between the anaesthetic methods? Participants, scheduled for total hip, total knee and unicomartmental knee arthroplasty, will be randomized to recieve spinal anaesthesia or general anaesthesia in relation to surgery. At 6 hours postoperatively a physiotherapist will conduct a 5-meter walking test to evaluate whether the participant can be safely mobilized.
Osteoarthritis is among the most prevalent form of degenerative joint disease in arthritis. The World Health Organisation identified osteoarthritis as one of the top ten most disabling cause of disease in developed countries, and the single most common cause of disability for elderly persons. In fact, worldwide statistics for men and women over 60 years of age with signs of symptomatic osteoarthritis are estimated to be at 9.6% and 18.0% respectively. In Hong Kong, the latest census revealed that 514,000 people suffer from degenerative arthritis, representing 0.7% of the population. Although these values are much lower than the international figures reported by the WHO, it is inevitable that the prevalence of osteoarthritis will continue to rise with an increasing trend of obesity and an aging population in Hong Kong. Similar to any other chronic disease with wide prevalence, the impact of osteoarthritis translates to a substantial socioeconomic burden on a societal level. Total knee arthroplasty has become the gold standard to manage the pain and disability associated with end-stage arthritis who have exhausted all conservative measures. Although contemporary advances in prosthesis design, surgical techniques, postoperative rehabilitation regimes have hasten patient's recovery, the restoration of proprioception and neuromuscular control is often prolonged despite solid rehabilitation regimes. Knee bracing is one of the non-pharmacological modalities designed to evenly distribute load and provide proprioceptive feedbacks for those with knee injuries or knee pain. There are four categories of knee braces for the purpose of prophylactic, functional, rehabilitative and unloader/off-load. This study will mainly be focusing on the effects of the unloader/off-loader brace. Previous studies have demonstrated the effects on alteration of kinematic variables, including range of movement (p=0.002), speed of walking (p<0.001) and knee adduction moment (p=0.001) for knee injuries and osteoarthritis as a part of the conservative management protocol. However, there have few studies that investigated whether proprioceptive knee bracing has any role in functional recovery post total knee arthroplasty.
The goal of this observational study is to gain insight in the natural course of pro-inflammatory factors and hemarthrosis in patients older than 18 with a recent knee trauma. The main question[s] it aims to answer are: - What is the natural course of pro-inflammatory factors and hemarthrosis in knee trauma? - What are the effects of inflammation and hemarthrosis on the anti-inflammatory potential of ASC's in order to better determine eligible patients and circumstances for ASC's therapy? Participants will: - undergo blood withdrawal - undergo knee arthrocentesis for synovial fluid sample collection - physical examination - fill out a questionnaire on knee complaints
This is a randomized clinical study, in which 150 patients with end-stage osteoarthritis will be enrolled to ROSA®-assisted knee arthroplasty or conventional knee arthroplasty. Patients are recruited at Zuyderland Medical Center, enrolled pre-operatively and followed up for 12 months post-surgery. In- and exclusion criteria are stated below. After recruitment, participants will be invited for a pre-operative visit. During this pre-operative visit Informed Consent is signed and completion of patient-reported outcome measures (PROMs) is checked. Additionally, measurements regarding body composition, strength and fitness and metabolic outcomes are performed. Participants will have a blood sample taken. Scans, adverse event and medication use will be confirmed. Participants will receive a ActiGraph for collecting data from physical activity. Of all patients, 72 will undergo additional measurements (gait, proprioception). During surgery ROSA- and surgery-data will be collected. Post-operative participants will have a 6-weeks, 3-month and 12-month visit. During these visits pre-operative measurements are repeated.
Feasibility, acceptability, and preliminary efficacy of combined transcranial direct current stimulation and mindfulness for pain after total knee arthroplasty
This pilot study will be a placebo controlled randomised intervention study in which participants with knee pain will be grouped into the diet intervention, exercise intervention, diet and exercise intervention or placebo arm. The study involves intake of dietary supplements and performing routine exercises which are commonly used and are not pharmacological agents. The end-points of the study are non-clinical outcomes. N= 120. 2x2 intervention with 30 individuals per block: placebo, diet only, exercise only, diet + exercise
The goal of this study is to determine if pain in one knee influences loading of the other knee during different types of walking. The main questions it aims to answer are: - How does unilateral knee pain affect contralateral knee joint loading during different types of walking? - Does movement and loading change at the hips, knees, and ankles during prolonged walking in persons with painful knee osteoarthritis? Participants will: - Fill out questionnaires/surveys - Complete clinical examinations - Walking on a treadmill under different types of walking conditions - Receive two knee injections For comparison purposes, researchers will also enroll healthy participants.
After knee arthroplasty rehabilitation is fundamental to patient's functional recovery, but in recent years there has been a growing interest in the possibility to prepare patients for surgery through a "prehabilitation" program. This two-parallel groups randomized clinical trial aims at evaluating the effects of a preoperative rehabilitation programme carried out at patient's home using advanced technologies, on subjects waiting for knee replacement. In particular, the primary objective of this study is to assess the superiority of a tele-prehabilitation programme compared to standard prehabilitation (remotely delivered with a booklet) in determining an improvement in lower limb function, as measured by the Western Ontario and McMaster Universities Osteoarthritis Index questionnaire, at the end of the programme. This study also aims at assessing possible differences between groups in muscle function, pain, autonomy in the activity of daily living, adherence to treatment and patients' satisfaction with the prehabilitation modality. Through the analysis of quadriceps muscle and blood samples, we will also evaluate possible changes in the expression of specific markers that the prehabilitation programme may be able to determine at muscle level. Both the intervention and the control groups will perform a prehabilitation program in the 6 weeks just before surgery. The program will include therapeutic exercises and educational contents. Subjects in the tele-prehabilitation group will receive a tablet with two accelerometers and a balance board for the remote execution of the program, while the control group will receive the same intervention through a booklet. Subjects recruited will be assessed at 5 timepoints: before starting the prehabilitation program, the day of surgery, 7± 2 and 15 ± 2 days after surgery, 3 months ± 7 days after surgery.
