Timothy E Hewett
Graft failure rates were higher and inferior subjective outcomes were observed after anterior cruciate ligament reconstruction in patients with generalized hypermobility. This is a clear and corroborative finding that is highly consilient with other reports of similar studies from the published literature. However, controversy remains regarding other potentially predictive and confounding variables. For example, age, activity level, sex, and dynamic neuromuscular control were not considered in this interesting, important, and potentially impactful study...

One of the most commonly injured structures of the thumb metacarpophalangeal (MCP) joint is the ulnar collateral ligament (UCL). An acute injury of this ligament is often amenable to primary repair. Despite the favorable outcomes of primary repair, the thumb is often restricted during initial healing of the ligament with immobilization and delayed rehabilitation. We present a novel technique to augment the repair of the UCL with suture tape to provide immediate biomechanical support and strength during the critical time of ligament healing...

Time of day is a key factor that influences the optimization of athletic performance. Intercollegiate coaches oftentimes hold early morning strength training sessions for a variety of factors including convenience. However, few studies have specifically investigated the effect of early morning vs. late afternoon strength training on performance indices of fatigue. This is athletically important because circadian and/or ultradian rhythms and alterations in sleep patterns can affect training ability. Therefore, the purpose of the present study was to examine the effects of morning vs...

BACKGROUND: Non-contact anterior cruciate ligament (ACL) injuries commonly occur when athletes land in high risk positions such as knee valgus. The position of the foot at landing may influence the transmission of forces from the ankle to the knee. Using an experimental approach to manipulate foot rotation positions, this study aimed to provide new insights on how knee valgus during single-leg landing may be influenced by foot positions. METHODS: Eleven male recreational basketball players performed single-leg drop landings from a 30-cm high platform in three foot rotation positions (toe-in, toe-forward and toe-out) at initial contact...

PURPOSE: To establish the relationship between the acute:chronic workload ratio and lower extremity overuse injuries in professional basketball players over the course of a competitive season. METHODS: The acute:chronic workload ratio was determined by calculating the sum of the current week's session rate of perceived exertion (sRPE) training load (acute load) and dividing it by the average weekly training load over the previous four weeks (chronic load). All injuries were recorded weekly using a self-reported injury questionnaire (Oslo Sports Trauma Research Centre Injury Questionnaire(20)) Workload ratios were modelled against injury data using a logistic regression model with unique intercepts for each player...

Knee osteoarthritis (OA) is a leading cause of disability among adults. Within the affected population, there exists a group of patients who have exhausted conservative treatment options and yet are not ideal candidates for current surgical treatments due to young age, early disease severity, or neutral mechanical knee alignment. For these patients, a new potential treatment option may be considered. We present an interesting case report of a young, ex-professional athlete treated with a minimally invasive load-altering implant (Atlas System) whose young age (26 years), disease status (tibiofemoral kissing lesions), and neutral mechanical limb alignment eliminated all traditional surgical treatment options such as high tibial osteotomy or arthroplasty...

Post activation potentiation (PAP) has shown improved performance during movements requiring large muscular power output following contractions under near maximal load conditions. PAP can be described as an acute enhancement of performance or an enhancement of factors determining an explosive sports activity following a preload stimulus. In practice, PAP has been achieved by complex training, which involves a combination of a heavy loaded exercise followed by a biomechanically similar explosive activity, best if specific for a particular sport discipline...
