Objectives: A pilot study was implemented to evaluate the efficacy of patient controlled analgesia (PCA) with continuous intra-articular infusion of ropivacaine following trapeziectomy with ligament reconstruction and tendon interposition.
Methods: Twelve patients were prospectively included. A catheter was placed into the trapezium void and connected to a PCA pump set on a continuous intra-articular infusion rate of ropivacaine: 2mg/ml. Patients were allowed to deliver additional boluses when analgesia was incomplete.
Results: Pain was evaluated less than 3/10 (Numeric Scale Evaluation) by 92% of the patients during the first 48 h. No toxicity of the local anaesthetic nor catheter-related complication were reported.
Conclusion: This preliminary study showed continuous basal and bolus infusion of ropivacaine through a single catheter placed into the trapezium void to provide an excellent postoperative pain control and to be related to a high patient's satisfaction level.

Correlation of fecal microbiome dysregulation to synovial transcriptome in an equine model of obesity associated osteoarthritis.

Background: Osteoarthritis (OA) is increasingly thought to be a multifactorial disease in which sustained gut inflammation serves as a continued source of inflammatory mediators driving degenerative processes at distant sites such as joints. The objective of this study was to use the equine model of naturally occurring obesity associated OA to compare the fecal microbiome in OA and health and correlate those findings to differential gene expression synovial fluid (SF) cells, circulating leukocytes and cytokine levels (plasma, SF) towards improved understanding of the interplay between microbiome and immune transcriptome in OA pathophysiology.
Methods: Feces, peripheral blood mononuclear cells (PBMCs), and SF cells were isolated from healthy skeletally mature horses (n=12; 6 males, 6 females) and those with OA (n=6, 2 females, 4 males).

Introduction: The use of corticosteroid injections for short-term pain relief for knee osteoarthritis can have deleterious adverse effects. Amniotic tissue has shown promise in vitro; therefore, this study compared a morcellized injectable amniotic tissue allograft to corticosteroid injection.
Methods: Eighty-one patients with symptomatic severe knee osteoarthritis (Kellgren-Lawrence grade 3 to 4) were prospectively randomized to either a double-blinded single injection of BioDRestore (Integra LifeSciences; n = 39) or triamcinolone acetonide (n = 42).
Efficacy of Intraoperative Intra-Articular Morphine on Post-Operative Pain and Opioid Consumption Following Hip Arthroscopy.

Department of Orthopedics and Rehabilitation, University of Iowa Hospitals and Clinics, Iowa City, Iowa, USA.
Background: The use of intraoperative intra-articular morphine has been suggested to lower postoperative pain scores and opioid use. We sought to evaluate the effectiveness of intra-articular morphine with 0.75% ropivacaine when compared to the use of ropivacaine alone.

Introduction: Olecranon fractures account for 5-7% of elbow fractures, making them a common injury. The majority of these fractures are treated surgically because they are intra-articular and can disrupt the elbow extensor mechanism. Mayo Type II fractures are displaced with a stable ulnohumeral joint, indicating intact ligamentous structures, particularly the anterior portion of the medial collateral ligament.
