Filter by:The goal of this interventional study is to examine whether a pain management technique of combined femoral and popliteal nerve block is effective in total knee arthroplasty patients. The main questions it aims to answer are: Are there differences in postoperative outcomes? Does the nerve block, age, preoperative quadriceps muscle strength and Oxford Knee Score of the patient predict early functional ability? Participants underwent total knee arthroplasty and assessments. Researchers compared pain management techniques to assess effects on postoperative outcomes and identified the importance of preoperative variables a predictors of early functional ability. Further research is required to refine postoperative pain management strategies.
As an intraoperative tool, a modern robotic total knee arthroplasty (TKA) system should be able to identify a patient's native femoral and tibial anatomy, as well as, assess ligament tension and gap balance. The surgeon in real time is then able to develop and execute a patient specific plan in terms of component size, alignment and rotation. In our institution we have begun to use, the OMNIBotics Knee system (Corin), which utilizes an active motorized knee spacer, BalanceBot, to objectively measure ligament tension and gap balance after the tibia has been cut and its alignment confirmed. This information is then processed through the OMNIbotics computer algorithm to appropriately size, align, and rotate the femur component to balance the flexion and extension gaps. The purpose of this study is to perform a randomized pilot study looking for an effect on early functional outcomes comparing robotic assisted TKA (RATKA) versus conventional TKA technique.
The purpose of this pilot randomized controlled trial is to investigate the effects of aromatherapy on postoperative anxiety and pain in total knee replacement patients. The main questions to answer are: Does Lavender-Peppermint Aromatherapy reduce post operative anxiety in patients after primary total knee replacement when compared to placebo? Does Lavender-Peppermint Aromatherapy reduce post operative pain in patient after primary total knee replacement when compared to placebo? Does Lavender-Peppermint Aromatherapy reduce postoperative opioid consumption after primary total knee replacement when compared to placebo? Does Lavender-Peppermint Aromatherapy reduce postoperative nausea and vomiting after primary total knee replacement when compared to placebo? Participants will be assigned to one of the following groups at random: - Intervention: Aromatherapy with the lavender-peppermint scent - Control: Aromatherapy with the almond oil scent Participants will also be asked to complete pre- and post-operative questionnaires. Researchers will compare both groups (intervention vs control) to see if aromatherapy reduces post-operative anxiety, pain, opioid intake, and nausea/vomiting.
This study will compare the postoperative recovery of two patient cohorts who attended outpatient physical therapy at two clinics in the Greenville, South Carolina area. The Usual Care cohort received care according to each clinic's pre-existing care guidelines. The CDS Cohort received care informed by a new clinical decision support (CDS) tool.
PLANNING PHASE- Qualitative interviews with Healthcare Professionals to assist in the development of a new Patient Reported Outcome Measure (PROM) to assess patient's emotional wellbeing, and perceptions of Total Knee Replacement (TKR) surgery for the treatment of knee arthritis.
Total knee replacement is one of the most painful orthopedic surgical procedures. Patients who undergo total knee replacement are usually older and have limited cardiac and pulmonary reserves. The increased sensitivity of elderly patients to drugs makes it necessary to choose postoperative analgesia agents and methods that have minimal side effects. Intrathecal injection of morphine to provide postoperative analgesia during the initial 24-h after the operation is a widely used technique, however, opioid therapy is limited because of the side effects (hypotension, pruritus, nausea, urinary retention, respiratory depression) and intolerance. Alpha-2 adrenergic agonists (clonidine and dexmedetomidine) have pharmacologic characteristics (sedation, hypnosis, anxiolysis, sympatholytic, and analgesia) that make them suitable as adjuvants to multimodal analgesia. Their anti-nociceptive effect is attributed to the stimulation of a2- adrenoceptors located in the central nervous system. The rationale for combining analgesics that produce similar therapeutic effects or synergistic interactions is to accentuate the analgesic efficacy and decrease the side effects by permitting dose reduction of each agent. Human studies on the antinociceptive effects of co-administrated intrathecal morphine (ITM) and dexmedetomidine in postoperative pain are still few. On the other hand, Abdel-Ghaffar et al., results do not support improved analgesia with the combination of intrathecal morphine and dexmedetomidine, despite the absence of significant adverse effects. We hypothesized that the addition of dexmedetomidine to ITM would improve the quality of perioperative pain control and decrease the side effects of postoperative systemic opioid use.
Despite best efforts to provide standardized and effective rehabilitation sessions post-total knee replacement (TKR), there are a few factors that may result in sub-optimal recovery in this group of patients. There is a need to develop innovative rehabilitation strategies that (i) provide patients with accurate cues allowing for better compliance and exercise performance, (ii) allow for therapists to ensure continuity of care, monitor compliance, and identify deviation from recovery trajectories post-discharge, prior to their first outpatient appointment, and (iii) reduce reliance on manpower and variability during rehabilitation sessions. Technological solutions that empower patients and allow home-based rehabilitation to take place without the need for real-time human supervision could be the key to improving effectiveness and lowering costs. A mobile application which detects key landmarks on the body for human pose estimation will allow patients to perform their rehabilitation exercises with real-time feedback allowing for proper execution of the exercises. Physiotherapists will be able to access the data generated from the exercise session via a command centre to monitor patients' recovery progress and compliance. The primary aim of this pilot study is to evaluate the feasibility of using a mobile application during rehabilitation in patients after a TKR surgery. The secondary aim is to study the effects of using a mobile application during rehabilitation on knee functional status, exercise self-efficacy, and treatment satisfaction after TKR surgery.
The purpose of this project is to determine if a change in patient reported pain, nausea and vomiting after total knee and hip arthroplasty could be observed with the substitution of Intravenous meloxicam for ketorolac in the current established peri-operative pain protocol and if these changes lead to a decrease in opioid consumption (in morphine equivalents).
To determine the effect of Otago exercise in Total Knee Replacement
Total knee arthroplasty (TKA) is a cost-effective treatment for end-stage knee osteoarthritis. It has demonstrable benefits such as reducing pain and improving activity and quality of life. Despite the decrease in pain after surgery, the expectations of patients regarding their physical functions are not fully realized. Physical performance tests and reporting tests are used to objectively evaluate physical function and reveal the patient's condition. It is known that physical performance tests better reflect post-surgical changes. In addition, it has been stated that there may be serious differences between the results of the reports based tests and the actual functional capacities of the patients. The 2-minute walk test and the 6-minute walk test are tests that are used in the evaluation of lower extremity physical performance and have been shown to be valid and reliable in different populations. However, a certain length of corridor is needed in order to carry out these timed walking tests. As an alternative to these, another test used in the evaluation of physical performance is the 2-minute step test. This test, which was developed in 1999, does not require much equipment and space, so the test can be easily applied in any environment. In this test, a height specific to each individual is determined (as high from the ground as the distance between the Spina iliaca anterior superior and the midpoint of the patella), and the participant is asked to raise and lower both knees, respectively, to this height for 2 minutes. These tests used in the evaluation of patients should be valid, reliable and sensitive. In clinical studies, reliability is an important psychometric property. Because stable data are necessary to provide accurate data on treatment effects or the amount of change observed over time. Another important psychometric property is validity. Validity is defined as the degree to which a concept is accurately measured in a quantitative study. Reliability studies of the 2-minute step test in active and sedentary lean adults have been conducted, but the psychometric evaluations necessary for its routine use in patients with TDP have not been performed.
