Contact times of change-of-direction manoeuvres are influenced by age and the type of sports: a novel protocol using the SpeedCourt ® system

AbstractPurposeSide-to-side asymmetry in side-cutting manoeuvres is a known risk factor for severe knee injury. Potential leg asymmetry during ground contact times of different change-of-direction manoeuvres was evaluated in athletes by means of the recently developed SpeedCourt® system. The hypotheses were that ground contact times and the limb symmetry index are affected by age and the type of sports.MethodsOne-hundred and sixty-five athletes (149 men, 16 women, age 16.5  ± 5.1) of popular team sports such as football, team handball and baseball were assessed by means of three different tests [side-hop, lateral change-of-direction (COD) and diagonal COD] using the SpeedCourt® system. Analysis included the factors age, sex, type of sports, ground contact time, leg symmetry index and limb dominance.ResultsDuring lateral but not diagonal COD tests, football players had shorter contact times than players of team handball (p = 0.026) and baseball (p = 0.015) of the same age group. The side-hop tests yielded differences in the leg symmetry index between players  16 years (p

AbstractPurposeThe study purpose is to characterize the sizes of the anterior cruciate ligament (ACL) insertion site and intercondylar notch in Chinese patients undergoing ACL surgery. The findings will provide a reference for individualized clinical treatment of ACL rupture.MethodsFor this study, 137 patients (102 males, 35 females) with an average age of 30.3  ± 9.5 years (range 14–52 years) undergoing ACL reconstruction were included. The tibial ACL insertion site length and width and the intercondylar notch width were measured on MRI and arthroscopically using a ruler. Descriptive s...

ConclusionDifferent methods for MCID calculation lead to different results. With the use of ROC curve analysis, patients with an improvement of at least 9 points for KSS-knee and 10 points for KSS-function scores experience a clinically important change, whereas those who have at least an improvement of 40 points for KSS-knee and 39 points for KSS-function scores experience a substantial clinical benefit. These findings can ensure clinical improvement from the patient ’s perspective and also aid in interpreting results from clinical studies.Level of evidenceIII.

Lall, Benjamin G. DombAbstractMost surgeons rely on the greater trochanter as the reference point to establish the anterolateral portal. Nevertheless, we believe that the anterosuperior iliac spine is a more reliable landmark. Unlike the greater trochanter, it is unaffected by leg rotation and is more easily identified by palpation. Abiding by the central tenet of medicine to “do no harm,” the technique described herein pre...

AbstractFracture of the polyethylene tibial post in the posterior-stabilized total knee prosthesis is often delayed in diagnosis due to its nonspecific symptoms and the radiolucent characteristic of polyethylene on conventional radiography. Therefore, the diagnosis is always established by arthroscopy. Notwithstanding recent advances in imaging modalities, we are presently aware of only two related case reports on MRI and even no reports about arthrographic or CT-arthrographic diagnosis of fractured tibial post. We hereby report a case of a 58-year-old female patient who developed recurrent knee pain during the third year ...

AbstractPurposeThe primary purpose of this study is to report the incidence of complications associated with outpatient total knee arthroplasty (TKA). Secondarily, 2-year minimum outcomes are reported.MethodsBetween 2013 and 2016, 928 patients underwent 1143 outpatient TKAs with the Vanguard Complete Knee System (Zimmer Biomet, Warsaw, IN). Patients were selected for outpatient surgery if they were medically optimized without a failing organ system and had sufficient support at home. Overnight stays, medical complications and early perioperative complications were assessed in this entire cohort. Two-year minimum follow-up ...

ProvencherAbstractCoracohumeral ligament pathology arises from acute trauma, capsular thickening, or congenital connective tissue disorders within the glenohumeral joint. Recent studies have highlighted the significance of this pathology in multidirectional shoulder instability because insufficiency of the rotator interval has become increasingly recognized and attributed to failed shoulder stabilization procedures. The diagnosis and subsequen...
