Despite relatively high reinjury rates after acute hamstring injuries, there is a lack of detailed knowledge about where and when hamstring reinjuries occur, and studies including imaging-confirmed reinjuries are scarce. ⋯ The majority of the hamstring reinjuries occurred in the same location as the index injury, early after RTS and with a radiologically greater extent, suggesting incomplete biological and/or functional healing of the index injury. Specific exercise programs focusing on reinjury prevention initiated after RTS from the index injury are highly recommended.

Platelet-rich plasma (PRP) is now widely used as a promising treatment for patients with tendinopathy. However, the efficacy of PRP treatment for tendinopathy is controversial mainly because of inconsistent results from human clinical trials and particularly because the concentration and effect of leukocytes in PRP remain largely unknown. ⋯ This study revealed the direct effects of different compositions of PRP on TSCs and provided basic scientific data to help understand the cellular and molecular mechanisms of the efficacy of PRP treatment in clinical use.

Liposomal Bupivacaine for Pain Control After Anterior Cruciate Ligament Reconstruction: A Prospective, Double-Blinded, Randomized, Positive-Controlled Trial.
Local anesthetics are commonly administered into surgical sites as a part of multimodal pain control regimens. Liposomal bupivacaine is a novel formulation of bupivacaine designed for slow diffusion of a single dose of local anesthetic over a 72-hour period. While early results are promising in various settings, no studies have compared pain management regimens containing liposomal bupivacaine to traditional regimens in patients undergoing anterior cruciate ligament (ACL) reconstruction. ⋯ ClinicalTrials.gov NCT02189317.

Tarsometatarsal (Lisfranc) joint injuries commonly occur in National Football League (NFL) competition; however, the career effect of these injuries is unknown. ⋯ More than 90% of NFL athletes who sustained Lisfranc injuries returned to play in the NFL at a median of 11.1 months from time of injury. Offensive and defensive players experienced a decrease in performance after return from injury that did not reach statistical significance compared with their respective control groups over a similar time period.

Previous studies have determined the percentage of studies presented at national orthopaedic surgery meetings that are eventually published in peer-reviewed journals. ⋯ A high proportion of studies accepted for publication in AJSM are presented at national and international meetings. AOSSM and AAOS Annual Meetings are the most common conferences at which these studies are presented, although international conferences account for a substantial proportion of AJSM-published study presentations.
