Complications Should Only Be A Small Concern When Undergoing ACL Reconstruction

Complications and Adverse Events of a Randomized Clinical Trial Comparing 3 Graft Types for ACL Reconstruction

Mohtadi N, Barber R, Chan D, and Paolucci EO. Clin J Sports Med. 2015. [Epub Ahead of Print].

Take Home Message: Of 330 patients who underwent an anterior cruciate ligament (ACL) reconstruction surgery, 27% reported an adverse event due to surgery within 2 years but only 2  adverse events (0.6%) were considered major complications and 24 (7%) required a repeat surgery. This suggests that overall, ACL reconstruction surgery is generally safe and the adverse events which do occur can be treated relatively successfully.

We often focus on the short-term benefits of an anterior cruciate ligament (ACL) reconstruction or the long-term outcomes of ACL reconstruction but we know very little about the adverse events (complications) within the first 2 years after surgery. By better understanding this, clinicians will be better equipped to counsel patients and explore strategies to prevent these adverse events. Therefore, Mohtadi and colleagues completed a prospective, double-blind randomized clinical trial and identified and reported all adverse events following ACL reconstruction using 3 different grafts.

The Scandinavian Journal of Medicine & Science in Sports has published new consensus recommendations on training and competing in the heat. The document discusses heat acclimatization, hydration, cooling strategies, and recommendations for event organizers.

To the MOON (and Back) with ACL Rehabilitation

Anterior Cruciate Ligament Reconstruction Rehabilitation: MOON Guidelines

Wright RW, Haas AK, Anderson J, Calabrese G, Cavanaugh J, Hewett TE, Lorring D, McKeznie C, Preson E, Williams G, and the MOON Group. Sports Health. 2015; 7(3): 239-243.

Take Home Message: Rehabilitation programs that incorporate early motion, limit open kinetic chain exercises prior to 6 weeks post surgery with a transition to normal open kinetic chain exercises, and incorporate neuromuscular training throughout are best practices during anterior cruciate ligament (ACL) reconstruction rehabilitation.

Anterior cruciate ligament (ACL) reconstruction rehabilitation programs are constantly being evaluated to determine best practices.  The Multicenter Orthopaedic Outcomes Network (MOON) group consists of 20 clinicians who are investigating many lower extremity injury outcomes.  At the beginning of their prospective cohort study (2005) they created an evidence-based rehabilitation protocol for patients after an ACL reconstruction. The goal was a program that could be performed in multiple clinical sites without expensive equipment.  The authors of this systematic review aimed to review literature from 2005 to 2011 for new evidence behind current ACL rehabilitation guidelines.

A Good Night’s Sleep Could Go A Long Way with Neurocognitive Performance

The effect of preinjury sleep difficulties on neurocognitive impairment and symptoms after sport-related concussion

Sufrink A, Pearce K, Elbin RJ, Covassin T, Johnson E, Collins M, Kontos AP. Am J Sports Med. 2015;43:830-840.

Take Home Message: Athletes who reported sleeping difficulties during preseason neurocognitive testing performed worse on neurocognitive exams after a concussion and reported more symptoms following a concussion compared with those who reported no difficulties sleeping.

Clinicians often use neurocognitive testing in a concussion-assessment protocol to compare baseline and post-injury scores for diagnosis and determining readiness to return to play. Neurocognitive testing can be influenced by many variables such as amount of sleep prior to baseline testing. It remains unclear if an individual’s sleep difficulties could also influence post-injury neurocognitive testing results. Therefore, the authors compared neurocognitive impairment and concussion-related symptoms between groups of athletes with and without self-reported sleep difficulties on a baseline Post-concussion Symptom Scale (PCSS).

For Better or Worse: Predicting Quality of Life After an ACL Injury

Baseline Predictors of Health-Related Quality of Life After Anterior Cruciate Ligament Reconstruction

Dunn WR, Wolf BR, Harrell FE, Reinke EK, Huston LJ, and Spinder KP. J Bone Joint Surg. 2015. [Epub Ahead of Print].

Take Home Message: Smoking and fewer years of education are predictive of poor mental and physical health 2 or 6 years after an anterior cruciate ligament reconstruction. Higher activity levels, younger age, better quality of life before surgery, and lower body mass index at the time of injury, were all associated with higher quality of life scores at 2 or 6 years post-surgery.

Anterior cruciate ligament (ACL) injury is common among physically active individuals and can often lead to long-term disability. Currently, only limited information concerning predictive factors of quality of life following an ACL reconstruction exists. If we knew predictors of quality of life after an ACL reconstruction this could help us advise patients, improve surgeon decision-making, and identify factors that we could target when treating an ACL injury. Therefore, Dunn and colleagues completed a prospective cohort study to determine the predictors of quality of life at 2 and 6 years post-ACL reconstruction.

Australian Institute of Sport and the Australian Paralympic Committee Position Statement: Urinary Tract Infection in Spinal Cord Injured Athletes

Australian Institute of Sport and the Australian Paralympic Committee Position Statement: Urinary Tract Infection in Spinal Cord Injured Athletes

Compton S, Trease L, Cunningham C, Hughes D. Br J Sports Med. doi:10.1136/bjsports-2014-094527

The Australian Institute of Sport and Australian Paralympic Committee has released a position statement regarding urinary tract infection in spinal cord injured athletes. The statement covers asymptomatic bacteriuria and dipstick testing, diagnosis of urinary tract infections, management of urinary tract infection, and prevention of urinary tract infection.

Screening with LESS

The Landing Error Scoring System as a Screening Tool for an Anterior Cruciate Ligament Injury – Prevention Program in Elite-Youth Soccer Athletes

Padua DA, DiStefano LJ, Beutler AI, de la Motte SJ, DiStefano M, & Marshall SW. Journal of Athletic Training. Online ahead of print, January 2015.

Take Home Message: The Landing Error Scoring System (LESS) can help us identify poor landing habits that may leave a young soccer athlete susceptible to an anterior cruciate ligament (ACL) injury. 

Anterior cruciate ligament (ACL) injuries are common in physically active and athletic populations.  Injury prevention programs are often implemented in high-risk groups such as soccer and basketball; however, there is limited research on screening tests that could be used to identify at-risk athletes. The authors of this study aimed to determine if the Landing Error Scoring System (LESS) can predict which young soccer players will have an ACL injury during a season.
