A hamstring strain injury (HSI) has become the most common noncontact injury in soccer. Isokinetic muscle strength deficits are considered a risk factor for HSIs. However, underpowered studies with small sample sizes unable to determine small associations have led to inconclusive results regarding the role of isokinetic strength and strength testing in HSIs. ⋯ This study identified small absolute strength differences and a wide overlap of the absolute strength measurements at the group level. The small associations between lower hamstring eccentric strength and lower quadriceps concentric strength with HSIs can only be considered as weak risk factors. The identification of these risk factors still does not allow the identification of individual players at risk. The use of isokinetic testing to determine the association between strength differences and HSIs is not supported.

Review Meta Analysis
Cartilage Restoration of the Knee: A Systematic Review and Meta-analysis of Level 1 Studies.
Focal cartilage defects of the knee are a substantial cause of pain and disability in active patients. There has been an emergence of randomized controlled trials evaluating surgical techniques to manage such injuries, including marrow stimulation (MS), autologous chondrocyte implantation (ACI), and osteochondral autograft transfer (OAT). ⋯ There is no significant difference between MS, ACI, and OAT in improving function and pain at intermediate-term follow-up. Further randomized trials with long-term outcomes are warranted.

Randomized Controlled Trial
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.
