BACKGROUND: Existing evidence regarding the value of preoperative education and/or exercise (prehabilitation) for patients undergoing total joint replacement is conflicting. The purpose of this study was to conduct an updated, comprehensive systematic review with meta-analyses to determine the longitudinal effects and efficacy of prehabilitation on postoperative outcomes in patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA). METHODS: We searched 11 electronic databases (MEDLINE, AMED, CINAHL, Embase, Scopus, ProQuest, PEDro, SportDiscus, PsycINFO, and Cochrane) from their inception to May 2016 for randomized controlled trials that compared changes in pain, function, strength, anxiety, and hospital length of stay following THA or TKA...

BACKGROUND: Botulinum toxin A (BTX-A) has been used to reduce spasticity in children with cerebral palsy (CP) for decades. The purpose of this study was to analyze to what extent BTX-A treatment was used to treat spasticity in a total population of children with CP. We investigated 1) the use of BTX-A in relation to age, sex, and Gross Motor Function Classification System (GMFCS) level, 2) the most common muscle groups treated with BTX-A in relation to the same variables, and 3) changes in the proportions of children treated with BTX-A between two time points (2010 and 2015)...

Proximal hamstring tendon avulsions are typically sustained during forced hip hyperflexion combined with knee extension. We present 3 cases of athletes with a proximal hamstring tendon avulsion caused by an alternative injury mechanism that also involves a considerable hip abduction component (flexion-abduction injury mechanism). All cases had at least one concurrent injury of the medial thigh muscles, either on the ipsilateral or contralateral side. The 2 elite athletes with this injury mechanism returned to sport at preinjury level relatively quickly...

OBJECTIVE: The preseason Nordic Hamstring Protocol (NHP) reduces hamstring strain injuries in football players. Despite persisting injury rates, elite clubs are reluctant to apply the NHP often over concerns of negative impacts on performance. This pilot study investigated if sprint or jump-performance outcomes tended to increase or decrease following implementation of the NHP in elite male soccer-players. RESULTS: Nineteen male soccer players from the Danish 1st division were randomised to perform NHP (27 sessions) during pre-season, or to control group (CG)...

BACKGROUND: Local infiltration analgesia offers effective postoperative analgesia after knee arthroplasty, but the role of its counterpart, local instillation analgesia (LIA), in anterior cruciate ligament reconstruction (ACLR) is unclear. This systematic review and meta-analysis evaluates the analgesic benefits of LIA for outpatient ACLR. METHODS: We sought randomized controlled trials investigating the analgesic effects of LIA versus control in adults having outpatient ACLR and receiving multimodal analgesia (excluding nerve blocks, which are examined in parts I and II of this project)...

INTRODUCTION: Pediatricians are more likely than mental health (MH) specialists to manage children's MH concerns, and multiple factors complicate their abilities to do so adequately. Integrated care initiatives mitigate systems-related shortcomings that hamstring MH management in primary care. These initiatives, which improve outcomes for adults, are not widespread for youth. Integrated health care for children with MH concerns requires regular collaborative communication among pediatricians and MH specialists...

BACKGROUND: Muscle-derived interleukin-6 (IL-6) not only enhances glucose and fat metabolism but also has an anti-inflammatory effect that can prevent the development of cardiovascular disease (CVD) and metabolic syndrome. Dynamic resistance exercise comprises a muscle shortening and a lengthening phase known as concentric and eccentric contraction respectively. We compared an acute bout of concentric exercise (CE) with eccentric exercise (EE) for the serum IL-6 concentration, myocardial oxygen consumption (MVO2) and rating of perceived exertion (RPE)...

EDITORIAL
Mark P Cote
There is considerable debate over the ideal graft for anterior cruciate ligament (ACL) reconstruction in athletes. The use of a hamstring autograft with preserved insertions is an approach to ACL reconstruction that may lead to earlier healing and less morbidity in comparison to a free hamstring autograft. When compared in a randomized trial, statistically significant but clinically irrelevant differences in clinical outcome and instrumented laxity were observed. These contradictory findings highlight the importance of examining the results from many vantage points and further demonstrate the misleading conclusions that may result from reliance on P values...

Treatment of proximal hamstring avulsions is challenging regarding both timing and choice of repair. In chronic situations, the tissue can become attenuated, bringing into question the need for adjunctive allograft. In general, proximal hamstring avulsions are affixed back to the ischial tuberosity with suture anchors, with allograft used as needed for chronic situations. This article reports on a novel technique of suspensory fixation with a unicortical button but without allograft to repair both acute and chronic proximal hamstring avulsions...

This assessor-blinded, randomized controlled superiority trial investigated the efficacy of the 10-week Nordic Hamstring exercise (NHE) protocol on sprint performance in football players. Thirty-five amateur male players (age: 17-26 years) were randomized to a do-as-usual control group (CG; n = 17) or to 10-weeks of supervised strength training using the NHE in-season (IG; n = 18). A repeated-sprint test, consisting of 4 × 6 10 m sprints, with 15 s recovery period between sprints and 180 s between sets, was conducted to evaluate total sprint time as the primary outcome...

57-year-old woman was recruited for a research study of muscle activation in persons with low back pain. She described a progressive worsening of left lower lumbar pain, which began 5 years prior without any precipitating incident, and intermittent pain at the left gluteal fold (diagnosed as a proximal hamstring tear 2 years prior). Ultrasound revealed marked anterior displacement of the L3-4 and L4-5 facet joints. The subject was recommended for a radiograph using a lateral recumbent view, which demonstrated a grade II spondylolisthesis...

The passive straight-leg-raise (PSLR) and the sit-and-reach (SR) tests have been widely used to assess hamstring extensibility. However, it remains unclear to what extent hamstring stiffness (a measure of material properties) contributes to PSLR and SR test scores. Therefore, we aimed to clarify the relationship between hamstring stiffness and PSLR and SR scores using ultrasound shear wave elastography. Ninety-eight healthy subjects completed the study. Each subject completed PSLR testing, and classic and modified SR testing of the right leg...
