Intravenous Regional Analgesia of Dexmedetomidine

Dexmedetomidine is a highly selective α₂-adrenergic receptor agonist that exerts its effects by inhibiting the release of norepinephrine at presynaptic nerve terminals, leading to reduced sympathetic activity; This mechanism results in analgesia, sedation, and anxiolysis without significant respiratory depression

Comparison of Nerve Blocks for Pain Relief After Knee Surgery

This retrospective observational study compares the postoperative analgesic effectiveness of ultrasound-guided fascia iliaca compartment block (FICB) with combined IPACK and genicular nerve block (GNB) in patients undergoing knee surgery under spinal anesthesia. The study includes 70 patients treated between July 2022 and July 2024. Postoperative pain scores, tramadol consumption, time to first mobilization, motor block, need for rescue analgesia, complications, and patient satisfaction are evaluated during the first 24 hours after surgery.

Comparison of Analgesic Efficacy and Impact on Motor Function in Knee Replacement Surgery: 0.1% Naropeine Tri-block Versus 0.5% Naropeine iPACK Saphenous Block - A Prospective Randomised Trial

Over the last two decades, perioperative analgesia has evolved. Spinal and epidural anaesthesia, once common, have been gradually phased out due to their side effects. The femoral block combined with the sciatic block, possibly with a perineural catheter, is now the gold standard for ensuring prolonged, high-quality analgesia. However, these blocks can cause muscle weakness in the quadriceps, limiting patients' functional recovery. To optimise functional rehabilitation, recent techniques favour more distal and selective blocks, such as the adductor canal (saphenous) block and the iPACK, which allow effective anaesthesia to be maintained whilst preserving motor function. However, these blocks do not always guarantee complete analgesia and may require additional blocks. The hypothesis of the current study is based on the idea that a proximal block targeting the femoral, obturator and sciatic nerves, administered with a low concentration of naropeine (0.1%), could provide more effective analgesia than a 0.5% saphenous iPACK block, whilst preserving motor function The originality of our approach in the current study lies in the use of dissociative proximal blocks performed with low concentrations of local anaesthetics, aimed at effectively covering the innervation of the knee whilst preserving motor function. The expected outcomes of this research are to optimise analgesic management for patients undergoing functional orthopaedic knee surgery, to promote early postoperative walking rehabilitation, to reduce the risk of chronic pain following knee arthroplasty, and to provide evidence to guide anaesthetic and post-surgical rehabilitation practices

Effects of Music Listening and Relaxation Interventions on Postoperative Recovery After Knee Surgery

This study aims to evaluate whether listening to music and using Emotional Freedom Techniques (EFT) can help patients recover better after knee arthroscopy. After this type of surgery, many patients experience pain, fear of movement (kinesiophobia), balance problems, and an increased risk of falling. In this study, patients will receive music listening and EFT as supportive, non-drug interventions during the postoperative period. The goal is to determine whether these simple and safe methods can reduce pain, decrease fear of movement, and lower fall risk, ultimately improving recovery. The findings of this study may help healthcare professionals, especially nurses, provide more holistic and patient-centered care after knee surgery.

Comparison of ACB With ACB and BiFeS Combination in Knee Arthroplasty Surgeries

The aim is to compare the postoperative analgesic effects of Adductor Canal and Biceps Femoris Short Head Blocks with Adductor Canal Block in patients undergoing Knee Arthroplasty surgery

FH ORTHO SAS Knee Observatory

The objective of this observatory is to generate additional real life clinical data in accordance with local regulation (i.e. Post-Market Clinical Follow-up (PMCF) study, a study carried out following the European Conformity (CE) marking of a device and intended to answer specific questions relating to clinical safety or performance (i.e. residual risks) of a device when used in accordance with its approved instructions for use (IFU). The difficulty of such an observatory is to be able to collect data on the different versions of the devices, on the different possible combinations of implants of an knee arthroplasty. The observatory must also be able to cover devices used in ligament reconstruction surgery. The observatory will be based on the principle of a "dynamic" cohort during the inclusion period, i.e. with possible inclusions to replace the premature exits. Technical solutions will be implemented to facilitate data collection from surgeons (electronic Case Report Form (eCRF) and from patients (Electronic Patient Reported Outcome (ePRO) on smartphone/tablet/computer) when feasible. The data to be collected and the different follow-up times are based on our state-of-the-art, clinical evaluation plans and clinical evaluation reports.
