Various types of cellular injection have become a popular and costly treatment option for patients with knee osteoarthritis despite a paucity of literature establishing relative efficacy to each other or corticosteroid injections. Here we aimed to identify the safety and efficacy of cell injections from autologous bone marrow aspirate concentrate, autologous adipose stromal vascular fraction and allogeneic human umbilical cord tissue-derived mesenchymal stromal cells, in comparison to corticosteroid injection (CSI). The study was a phase 2/3, four-arm parallel, multicenter, single-blind, randomized, controlled clinical trial with 480 patients with a diagnosis of knee osteoarthritis (Kellgren-Lawrence II-IV).

The injection of biologic products for musculoskeletal pathologies is an emerging and promising field; however, dubious and unsafe uses for these products are often marketed. The Food and Drug Administration (FDA) has determined the need for varying degrees of regulation for these products for safety and efficacy. These regulations are frequently updated and federally enforced.

Background: Intra-articular injections of human mesenchymal stromal cells (hMSCs) have shown promise in slowing cartilage degradation in posttraumatic osteoarthritis (PTOA). Clinical use of cell therapies for osteoarthritis has accelerated in recent years without sufficient scientific evidence defining best-use practices. Common recommendations advise patients to avoid nonsteroidal anti-inflammatory drug (NSAID) use before and after cell injection over concerns that NSAIDs may affect therapeutic efficacy.

Background: Acute and degenerative musculoskeletal disorders are among the most common etiologies of disability worldwide. Recently, there has been interest in the field of regenerative medicine to bridge the gap between conservative and surgical management of these conditions. Autologous bone marrow concentrate is one type of injectate that has increased in popularity over the last few decades.

The knee joint is one of the most frequently injured joints in the body, and the resulting injury may often lead to the presence of a bloody effusion, or hemarthrosis. The acute management of this condition can have long-lasting implications, and may ultimately result in the early onset of osteoarthritis in this population. Heme, a breakdown product of erythrocytes, and associated pro-inflammatory mediators, are known to have deleterious interactions with cartilage and synovium.

Objectives: Ultrasound (US) is increasingly being used as an extension of the physical examination on the sidelines, in training rooms, and in clinics. Anterior cruciate ligament (ACL) injury in sport is common, but the literature on US findings after acute ACL rupture is limited. Three indirect US findings of ACL rupture have been described, and this study assessed the validity of these indirect signs.

Design: Primary care sports medicine fellowship directors (FDs) and fellowship faculty were surveyed regarding preferences for accepting applicants into their programs.

Setting: Survey study.

Aim: Significant variability exists in the literature, with no clear consensus to the optimal protocol after a regenerative procedure. Given this uncertainty, the authors systematically reviewed the literature cataloging the different variables that may influence outcomes.

Methods: Search was limited to randomized clinical trials and prospective cohort studies of regenerative procedures for the treatment of tendinopathy.

High-resolution ultrasonography can help clinicians visualize key anatomic structures of the elbow and guide periarticular and intra-articular injections. Historically, most procedures done around the elbow have been done using landmark guidance, and few studies have reported the accuracy of ultrasonography-guided injections in the elbow region. This article reviews common musculoskeletal disorders about the elbow that can be evaluated with ultrasonography, reviews the literature on ultrasonography-guided injections of the elbow region, and describes the senior author's preferred approach for the most commonly performed elbow region injections.

Posttraumatic headaches (PTHs) are one of the most frequently reported symptoms after a sport concussion, and treatment options for chronic PTH are limited. In this report, we present a case of a 17-year-old boy with persistent PTH after a sport concussion successfully treated with an intranasal sphenopalatine block.

Pain and dysfunction related to tendinopathy are often refractory to traditional treatments and offer a unique challenge to physicians, because no gold standard treatment exists. Injectable biologics may represent a new modality in conjunction with a multifaceted treatment approach. Platelet-rich plasma (PRP) injections are not associated with the systemic or tendon degradation risks of corticosteroids or the inherent risks of surgery.

In summary, LBP is a common problem for the young adult athlete, with discogenic pain being the most common of all etiologies. Although rare, more serious etiologies such as tumor or infection should be included in the differential diagnosis until effectively ruled out. Regardless of the cause, nonoperative and conservative strategies should be the cornerstone of treatment, owing to the favorable natural history of most LBP etiologies.
