Filter by:The purpose of this study is to examine the effects of two technology interventions on health outcomes (e.g., physical activity, sedentary behavior, physical function, pain) after knee replacement at 2 and 5 months .
Valgus high tibial osteotomy (HTO) and unicompartmental knee arthroplasty (UKA) are established treatment options for patients with medial compartmental osteoarthritis (OA) of the knee.However, the clinical outcomes of these treatment modalities for unicompartmental OA have become subjects of debate.
The study compares three different analgesic techniques in order to determine which one serves as the optimal method for postoperative pain management after Total Knee Arthroplasty in patients suffering from Osteoarthritis
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.
Studies have shown that the lifetime risk of developing symptomatic knee osteoarthritis is 40% in men and 47% in women; and the risk can be increased to 60% when the patient's BMI reaches 30 kg/m2. In this population, knee replacement is the most common, effective, and cost-effective method in all treatments with reducing pain, improving joint function and quality of life. Postoperative cognitive dysfunction (POCD) is a common complication in the elderly, and its incidence can reach 25-40% in major non-cardiac surgery. As for POCD can prolong hospital stay, increase mortality and morbidity, and increase social and economic burden, it is especially important for the prevention and treatment of POCD. However, The mechanism of POCD is still unclear. Studies suggest that it may involve inflammation and oxidative stress in the central nervous system. But for the elderly, they are in a state of low inflammatory response. At the same time, surgery and tourniquets also can trigger or aggravate inflammatory response. Once the inflammatory factors released into the blood circulation, they can act on the central nervous system in a variety of ways. As a result,elderly patients are more likely to develop POCD. In addition, some studies have shown that pain can also increase cognitive burden. Aspirin, its pharmacodynamic effects includes anti-inflammatory and analgesic effects which may have a certain effect on the prevention of POCD.
The trial will contribute to the development of an innovative algorithm that aims to simplify and improve preoperative knee surgical decision. This will be made by automatically extracting anatomical informations from different images acquired on the patient (scanner, MRI, radiography).
Osteoarthritis of the knee is a common disease of the elderly and knee arthroplasty is indicated in severe cases to improve long term pain and function. Along with perioperative quality analgesia, functional recovery is paramount in the postoperative period.Loco-regional techniques provide effective analgesia and can mitigate several side effects of systemic opioids administration. Also, adequate motor sparing analgesia( to prevent weakness of the thigh muscle) following total knee arthroplasty (TKA) is therefore paramount to ensure effective rehabilitation, early recovery, readiness to discharge or timely hospital discharge. There are several motor sparing regional technique described in literature. Adductor canal block (ACB), use of intrathecal ( IT) morphine and local infiltration by the surgeons (LIA) are such examples. Previous studies have shown the combination of ACB and IT morphine to be superior than LIA in providing analgesia. Posterior knee infiltration (IPACK), involves blocking the branches of the tibial nerve which provides sensory innervation for the posterior aspect of the knee. In combination with ACB, a motor sparing analgesic intervention is possible for knee arthroplasty. Rationale for doing the study is to evaluate 1. The effectiveness of IPACK block as a part of multimodal analgesic approach to knee arthroplasty surgery. 2. Enhanced recovery from superior motor sparing analgesia. 3. early hospital discharge We hypothesize that, following total knee arthroplasty surgery, the combination of continuous adductor canal catheter and I-PACK blocks will achieve a decrease in the time to readiness to hospital discharge as measured by the following four criteria: (1) adequate analgesia; (2) independence from intravenous opioids; (3) ability to independently stand, walk 3 m (metres), return, and sit down; and (4) independently ambulate 30 m without limitation of time. We postulate this will occur by providing superior motor-sparing analgesia compared to LIA for knee arthroplasty surgery.
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.
