Peripheral nerve stimulation for chronic knee pain following total knee arthroplasty: a systematic review.

Chronic knee pain following total knee arthroplasty (TKA) affects a subset of patients that is refractory to pharmacological and non-pharmacological modalities. Peripheral nerve stimulation (PNS) has been used in patients with chronic knee pain following TKA and has shown some efficacy. Methods: Comprehensive search of Ovid Medline, Elsevier Embase, Cochrane Central Register of Controlled Trials, CINAHL Plus with Full Text, Scopus, SPORTDiscus with Full Text and the Web of Science platform. From inception to August 2022, for studies using PNS to treat chronic knee pain following TKA. Primary outcomes included pain scores, functional status and medication usage. Results: Nine studies were extrapolated with all demonstrating effectiveness of PNS for patients with chronic knee pain following TKA. Discussion: PNS for chronic knee pain following TKA has been shown to be an efficacious treatment modality. The level of evidence is low and more research is needed to assess its safety and effectiveness.

Interventional Spine Course: Improving Fluoroscopic Safety and Procedural Efficacy Among Physical Medicine and Rehabilitation Residents Using a Lecture and Model-Based Curriculum.

ABSTRACT: Therapeutic interventional techniques using fluoroscopy are often used in the management of spinal pain. Currently, there are no standardized means of instruction and assessment of fluoroscopic interventional spinal procedures for physiatry trainees. The aim of our study is to evaluate the utility of an interventional spine training course for physical medicine and rehabilitation residents in improving safety and efficacy when performing these procedures. We performed a prospective multiple cohort study analyzing interventional spine knowledge and procedural ability among physical medicine and rehabilitation residents after implementing a training course that used lectures, hands-on training, and video-recorded objective structured clinical examination self-assessments. Of the total of 28 physical medicine and rehabilitation residents over the 2-yr study period, each class saw a statistically significant improvement in mean objective structured clinical examination scores from pre-examination to postexamination ( P < 0.05). Written examination scores also had a statistically significant preimprovement to postimprovement in the postgraduate years 2 and 3 classes. Our study supports the use of an interventional spine course for physical medicine and rehabilitation residents, and by following the existing cohorts and adding more cohorts in the future, we will continue to demonstrate valuable and comprehensive results.

Spinal cord stimulation for neuropathic pain following traumatic spinal cord injury: a case report.

INTRODUCTION: Neuropathic pain is a common complication of spinal cord injury (SCI), and is notoriously difficult to adequately treat. Gunshot wounds (GSW) near the spinal cord may cause intractable chronic pain through spinal/nerve root transection, or reactive tissue formation resulting in nerve root compression from retained bullet fragments (RBF). CASE PRESENTATION: This case report describes a 30-year-old man with a T12 AIS B incomplete spinal cord injury with paraplegia secondary to multiple GSW who presented with severe bilateral lower extremity dysesthesias and muscle spasms. Symptoms failed to improve with oral antispasmodic medications. After being diagnosed with Complex regional pain syndrome (CRPS) type I secondary to an SCI via GSW, he underwent a spinal cord stimulator (SCS) trial, which improved his symptoms by greater than 80%. DISCUSSION: Neuropathic pain refractory to conservative treatment may benefit from SCS. Effects of therapy go beyond gate-theory in SCI patients, and may benefit patients at the cellular and molecular level. Our case demonstrates the effectiveness of SCS treatment in a patient who developed CRPS type 1 after GSW resulting in SCI.

The Down Side of Prone Positioning: The Case of a Coronavirus 2019 Survivor.

The coronavirus 2019 pandemic has resulted in a surge of patients with acute respiratory distress syndrome. Prone positioning may be used in such patients to optimize oxygenation. Severe infections may leave survivors with significant functional impairment necessitating rehabilitation. Those who have experienced prolonged prone positioning are at increased risk for complications not typically associated with critical illness. This case report describes the course and clinical findings of a survivor of acute respiratory distress syndrome due to coronavirus 2019 who was prone positioned while in intensive care and subsequently admitted to an inpatient rehabilitation facility. Her related complications, as well as those described in the literature, are reviewed. Critical elements of a comprehensive rehabilitation treatment plan for those who have been prone positioned, including implementation of preventive strategies, as well as early recognition and treatment of related injuries, will be described.

Locking Plate Fixation in a Series of Bicondylar Tibial Plateau Fractures Raises Treatment Costs Without Clinical Benefit.

OBJECTIVES: To compare outcomes and costs between locking and nonlocking (NL) constructs in the treatment of bicondylar tibial plateau (BTP) fractures. DESIGN: Retrospective cohort study. SETTING: Level 1 academic trauma center. PATIENTS: All patients who presented with complete articular, BTP fractures OTA/AO 41-C and Schatzker VI between 2013 and 2015 were screened (n = 112). Patients treated with a mode of fixation other than plate-and-screw were excluded. Fifty-six patients with a minimum follow-up of 12 months were included in the analysis. INTERVENTION: Operative fixation of BTP fractures with locking (n = 29) or NL (n = 27) implants. MAIN OUTCOME MEASUREMENTS: Implant cost, patient-reported outcomes (PROMIS physical function and pain interference), clinical, and radiographic outcomes. RESULTS: There were no differences between the 2 groups with respect to demographics, injury characteristics, radiographic outcomes (change in alignment), or clinical outcomes (PROMIS, reoperation, nonunion, and infection). Implant costs were significantly greater in the locking group compared with the NL group (mean L, $4453; mean NL, $2569; P < 0.01). CONCLUSIONS: This study demonstrated improved value of treatment (less cost with no difference in clinical outcome) with NL implants for BTP fractures when dual-plate fixation strategies are performed. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
