BACKGROUND AND OBJECTIVES: Percutaneous peripheral nerve stimulation (PNS) is an analgesic modality involving the insertion of a lead through an introducing needle followed by the delivery of electric current. This modality has been reported to treat chronic pain as well as postoperative pain following knee and foot surgery. However, it remains unknown if this analgesic technique may be used in ambulatory patients following upper extremity surgery. The purpose of this proof-of-concept study was to investigate various lead implantation locations and evaluate the feasibility of using percutaneous brachial plexus PNS to treat surgical pain following ambulatory rotator cuff repair in the immediate postoperative period...

Characterization of the main tibiofemoral ligaments is an essential step in developing patient-specific computational models of the knee joint for personalized surgery pre-planning. Tensile tests are commonly performed in-vitro to characterize the mechanical stiffness and rupture force of the knee ligaments which makes the technique unsuitable for in-vivo application. The time required for the limited noninvasive approaches for properties estimation based on knee laxity remained the main obstacle in clinical implementation...

Ultrasound (US) is an excellent imaging tool to evaluate most of the structures in the knee joint. US is useful in various applications of regenerative medicine, starting from the biomaterial harvesting stage of the procedures, it can thus/conveniently be used for the diagnosis and treatment of various forms of knee osteoarthritis (OA) where the interventions need to be carried out under US guidance. In this paper, we have reviewed US guided bioharvesting of venous blood, bone marrow and adipose tissue, the US evaluation of the knee joint and the relevant findings in knee OA along with US guided regenerative interventions for the knee joint...

BACKGROUND AND OBJECTIVES: Peripheral nerve block is an important component of the multimodal analgesia for total knee arthroplasty. Novel interventional techniques of ultrasound-guided nerve block supplying the posterior knee joint capsule require knowledge of the innervation of the posterior capsule. The objectives of this cadaveric study were to determine the course, frequency, and distribution of the articular branches innervating the posterior knee joint capsule and their relationships to anatomical landmarks...

BACKGROUND: Deep vein thrombosis (DVT) remains a significant cause of morbidity after injury. Lower extremity duplex ultrasound screening (LEDUS) is designed to identify early, asymptomatic DVTs in moderate and high risk patients. We sought to describe when thrombus is detected and identify which trauma patients benefit from LEDUS. MATERIALS AND METHODS: A retrospective review was conducted on trauma patients who were moderate or high risk for venous thromboembolism based on risk assessment profile (RAP) scoring...

Introduction: The overuse and repetitive loading of a bone cause a stress fracture, commonly occurring in the weight-bearing structures of the lower extremities of athletes, but rarely the patella. Patella stress fractures are an extremely rare occurrence. Müller first described a patella stress fracture in 1943; however, we could find <15 reported cases in literature since that time. Thus, some uncertainty exists as to the proper treatment of this very rare condition. Case Report: A female collegiate gymnast presented with 2-months of anterior knee pain, and initial radiographs revealed a non-displaced patella stress fracture...

BACKGROUND: Fever of unknown origin is often a diagnostic dilemma for clinicians due to its extremely broad differential. One of the rarer categories of disease causing fever of unknown origin is malignancies; of these, soft tissue sarcoma is one of the least common. Soft tissue sarcomas make up < 1% of all adult malignancies and often do not present with any systemic manifestations or neoplastic fevers. CASE PRESENTATION: A 73-year-old Caucasian woman presented with a 2-week history of fever and profound fatigue...

Background: The adductor canal block (ACB) is an effective intervention for postoperative analgesia following total knee arthroplasty (TKA). However, the ideal ACB regimen has not yet been established. We compared the analgesic effects between a continuous ACB group and fentanyl-based intravenous patient-controlled analgesia (IV-PCA) with a single-shot ACB group. Methods: Patients who underwent TKA were randomly allocated to either a continuous ACB group (Group CACB) or IV-PCA with a single-shot ACB group (Group IVACB)...

Knee pain caused by osteoarthritis (OA) is commonly seen in geriatric patients. Patients with knee OA are often complicated with joint pain, soreness, and weakness. The injection of autologous platelet rich plasma (aPRP) has been proven to be effective in treating mild knee OA. The effect of injecting aPRP in treating moderate to severe degrees of knee OA remains controversial. This study aimed to evaluate the effectiveness of aPRP in treating patients with at least grade 2 on the Kellgren and Lawrence system for the classification of knee OA using a proteomic approach and clinical evaluation tool of Lequesne index...
