Filter by:Backwards walking has been shown to improve balance and walking in patients who have knee Osteoarthritis. It is not known if these benefits may also be seen after surgery in patients who have had a hip or knee replacement because of Osteoarthritis. This study will look to see if it is possible to conduct a bigger study into how effective backwards walking may be after joint replacement. Patients who come to the Nuffield Orthopaedic Centre in Oxford for a hip or knee replacement will be invited. They will be placed into one of two groups at random: a group where they have a course of physiotherapy plus a backwards walking programme or a group where they have a course of physiotherapy. The physiotherapy will last for 12 weeks and those who take part will have two study assessments. The first will be before any treatment and patients will complete five measures and also be issued with a simple tick box diary to complete over the 12 weeks. The second assessment will be after the treatment and will involve the same five measures and the diaries will be collected in. Participants at this assessment will also be asked if they would like to take part in an interview for the study. This is to see what the patients thought of the study. During the study the researcher will record things such as how many patients say 'yes' to the study and how many participants drop out of the treatment, to understand if a bigger study could take place.
The purpose of this study is to test whether adding a treatment using pain neuroscience education (PNE) and multimodal physiotherapy to usual care, in subjects with knee osteoarthritis and pain catastrophizing, who are scheduled for a total knee arthroplasty (TKA), is more effective than only usual care. There is a high evidence level of different systematic reviews, which support the efficacy of physiotherapy treatments combined with behavioural/educational techniques aimed to reduce pain catastrophism, pain and disability in other pathologies. The primary aim of that kind of interventions is to help the subjects to reconceptualise its own pain understanding and its role on the recovery process, as well as promoting an increase of activity and encourage the subject to resume its usual activity instead of continuing to avoid it.
The aim of this observational study is to assess whether patient reported pain levels correlate with a Pain Index derived from deviations in multivariate physiology biomarkers captured in real-world setting. This study will be conducted using a clinical-grade wearable sensor to continuously monitor patient's physiology (pain related biomarkers) and allow subject participant to actively report their pain score, symptoms and quality of life using a mobile-based application.
The purpose of this study is to examine the feasibility and preliminary efficacy of a physical therapist led physical activity intervention for knee replacement patients within an outpatient physical therapy facility.
The knee osteoarthritis becoming a leading cause of disability among older adults' population. When conventional treatments fail, a total knee arthroplasty (TKA) is suggested. Although TKA treatment significantly reduces pain and improve mobility of patients, there is still high prevalence of patients whose neuromuscular function is impaired up to three years following TKA, which can be directly prescribed to poor or/and inadequate rehabilitation practice. Thus, motor imagery (MI) is proposed as additional rehabilitation tool to convention physical therapy to reduce decline of neuromuscular function in early days post-surgery. Recent studies showed that MI could facilitate learning and acquisition of motor skills, as well as maintain and retain previously acquired motor skills, which may be beneficial for those who undergo TKA. It represents an incentive in the process of motor learning and the transfer of the mental scheme of the motion pattern into the process of movement execution. Measuring neuromuscular function pre- and post-TKA could be unique opportunity to provide empirical evidence about its additional therapeutic effects. Outcomes of proposed research project could serve to improve existing intervention programs applied in rehabilitation protocols following TKA surgery as well as other orthopedic interventions. This would also contribute to the successful return of individuals after an injury to their everyday working routine. We hypothesized that MI practice group will experience better both subjective and objective measures of functional performance compared to control group that will be subjected to routine physical therapy only.
To evaluate the progression on patients suffering from end stage OA whilst being on the waiting list for TKR
This is a prospective randomized control trial that aims to investigate fixation of implants after revision total knee replacement. The investigators are comparing long-stemmed revision implants with hybrid cementation to short-stemmed primary implants with augment using a special type of x-ray imaging (radiostereometric analysis) to assess implant movement over time. The investigators are also comparing costs and patient-reported outcomes between the groups.
This study is a prospective, randomized, single center, study to evaluate Zip Closure Device in subjects undergoing knee arthroplasty. Patients identified as candidates for knee arthroplasty and meet the study selection criteria will be approached and considered for the study. Knee Arthroplasty of 40 subjects will be enrolled where 20 subjects will receive ZipLine and 20 subjects will receive Staples.
The purpose of this study is to determine which technique for catheter placement in continuous femoral nerve block (FNB) is most successful - guidance with (1) ultrasound or (2) nerve stimulation and ultrasound. Sensory and motor assessment scores will be obtained post-FNB. Patient controlled analgesia and opiate consumption is also recorded along with pain scores for the first 48 hour post-FNB.
This study is a randomized clinical trial comparing standard medial para-patellar total knee arthroplasty with a quadriceps sparing mid-vastus approach. Patients who are medically well and have a good support structure at home will be randomized to a standard or quadriceps sparing surgical approach stratified by type of analgesia (adductor canal block or local infiltration). We will compare patient satisfaction and costs from the perspective of the Ministry of Health, the institution, society and the patient.
