Actual motor competence (MC), perceived motor competence (PMC), and health-related fitness (HRF) exhibit a dynamic and reciprocal relationship in child populations, but little is known about the nature of these relationships in young adulthood. The purpose of the study was to assess these relationships in a sample of college-aged males. A total of 55 participants enrolled in an undergraduate Kinesiology course completed the study. Perceived motor competence (PMC) was assessed with the Physical Self-Perception Profile questionnaire; MC was assessed using maximum throw and kick speed and maximum jump distance; HRF was assessed with a two-minute push-up test, two-minute sit-up test, and the Multistage 20-m Shuttle Run Test...

INTRODUCTION: Since William Clancy (1979) and Richard Ferkel (1997) publications, the technique of peroneal groove deepening in patients with chronic dislocation, has been used with very satisfactory results and few complications. The aim of the present study is to describe a new minimally invasive technique of peroneal groove deepening with burs and specific percutaneous surgery instrumentation and without fibula osteotomy; and to evaluate the clinical and imaging results, in 5 patients operated with this technique...

Background: Despite the relatively high number of cases of acromioclavicular joint (AC) separation in the athletic population, optimal clinical outcomes are not achieved in every case. Limited data exist regarding the prevalence of intra-articular glenohumeral pathologies (IAPs) associated with acute AC separation of all injury grades. Purpose: To determine the prevalence of IAPs associated with AC separation, regardless of severity. Study Design: Case series; Level of evidence, 4...

Surgical management for chronic lateral ankle ligament instability is useful when patients have failed nonoperative modalities. Open anatomic reconstruction is an effective method of stabilization. Ankle arthroscopy is a recommended to address intra-articular disorder before stabilization. An anatomic approach provides full range of motion, stability, and return to sport and activity. Allograft or suture tape augmentation can be useful for patients with generalized ligamentous laxity, patients with high body mass index, and elite athletes...

BACKGROUND: The purpose of this study was to evaluate the effects of noninvasive ankle distraction on intraoperative somatosensory evoked potentials (SSEPs) and peripheral nerve sensibility of the foot during ankle arthroscopy. METHODS: Twenty patients undergoing ankle arthroscopy were prospectively evaluated using noninvasive ankle traction. All had preoperative clinical examination with baseline neurologic evaluation and static 2-point discrimination (2PD) test...

BACKGROUND: Treatment of osteochondral lesions of the talus (OLTs) in children presents a difficult clinical challenge, with few large series reported. PURPOSE: To evaluate functional and radiographic outcomes for children and adolescents undergoing arthroscopic treatment of symptomatic OLT with a minimum follow-up of 2 years. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Patients were identified who had symptomatic OLT treated arthroscopically with marrow stimulation techniques...

BACKGROUND: Well-designed foot and ankle clinical outcomes research requires region-specific subjective outcome measures. Many foot and ankle-specific instruments are now available. Determining which instruments to choose is daunting. We present a patient survey to determine the most relevant questions pertaining to them. METHODS: Sixteen foot and ankle-specific outcome instruments were chosen based on popularity, emphasizing valid, reliable, responsive scores. Subjective portions were consolidated and given to 109 patients with osteochondral lesion of the talus (OLT) (39), ankle instability (35), and ankle arthritis (35)...

Recent literature suggests that adults do not necessarily develop osteoarthritis if they have an osteochondral lesion of the talus (OLT). The purpose of this study was to determine if children with OLT are at risk to develop any radiographic evidence of early joint degeneration despite treatment efforts. Fifty-six ankles were identified over 6 years with stable OLT that underwent operative treatment. Preoperatively, each lesion was classified according to Berndt-Hardy for radiographs, Hepple for MRI, and Ferkel and Sgaglione for computed tomography...

BACKGROUND: The impact of patient sex on the prevalence of foot and ankle injuries has been established. Reporting of differences on treatment outcomes is lacking. The purpose of this study was to identify trends in sex-specific outcomes across high-impact journals over a 5-year time period. METHODS: Two independent investigators reviewed journal issues published during 2 calendar years (2011 and 2016) in the 5 highest-impact orthopedic foot and ankle/sports subspecialty journals ( Foot & Ankle International [ FAI ], Foot and Ankle Surgery [ FAS ], American Journal of Sports Medicine [ AJSM ], Arthroscopy , and Knee Surgery, Sports Traumatology, Arthroscopy [ KSSTA ])...

Background: Motor competence and health-related fitness are important components for the development and maintenance of a healthy lifestyle in children. This study examined cross-cultural performances on motor competence and health-related fitness between Portuguese and U.S. children. Methods: Portuguese ( n  = 508; 10.14 ± 2.13 years , mean ± SD) and U.S. ( n  = 710; 9.48 ± 1.62 years) children performed tests of cardiorespiratory fitness (Progressive Aerobic Cardiovascular Endurance Run), upper body strength (handgrip), locomotor skill performance (standing long jump), and object projection skill performance (throwing and kicking)...

BACKGROUND: The evidence supporting best practice guidelines in the field of cartilage repair of the ankle are based on both low quality and low levels of evidence. Therefore, an international consensus group of experts was convened to collaboratively advance toward consensus opinions based on the best available evidence on key topics within cartilage repair of the ankle. The purpose of this article is to report the consensus statements on "Scaffold-Based Therapies" developed at the 2017 International Consensus Meeting on Cartilage Repair of the Ankle...

Arthroscopic ankle arthrodesis is the treatment method of choice to achieve good clinical scores, faster time to union, fewer complications, and shorter hospital stay. However, the union rate, reoperation rate, and operative time are similar to open arthrodesis. The choice of which method to use for arthrodesis is influenced by surgeon preference and experience, clinical presentation, and equipment availability. Overall, we must choose the method of ankle arthrodesis that gives the best result with the least morbidity to the patient...

PURPOSE: The purpose of our study was to determine the results of arthroscopic ankle arthrodesis (AAA) and how the procedure affects adjoining joints and functional scores. METHODS: Between 1993 and 2013, 116 patients (120 ankles) underwent AAA. Nineteen ankles were lost to follow-up due to death, insufficient radiographic studies, or inability to contact, resulting in 97 patients (101 ankles). Mean age at surgery was 61.1 years (range, 35.8-79.6 years); mean follow-up was 86 months (range, 24-247 months)...

The objective of this study was to characterize magnetic resonance imaging (MRI) findings and correlate with clinical results in patients who underwent autologous chondrocyte implantation (ACI) of osteochondral lesions of the talus (OLT). METHODS: Twenty-four grafts were evaluated at a mean 65.8 months after ACI for OLT. MRI was performed on a 1.5-T GE scanner using multiple sequences. Graft appearance was compared with preoperative MRI and evaluated for 6 criteria: defect fill, surface regularity, signal pattern, bone marrow edema, subchondral plate irregularity, and presence of cystic lesions...

Recalcitrant osteochondral lesions of the talus present a difficult problem to the treating surgeon. Anterior and posterior approaches have been studied to facilitate treatment access. Current research highlights the accessibility of an osteochondral lesion to treatment from an anterior or posterior approach and shows the importance of foot position and noninvasive distraction to facilitate treatment. Moreover, it is important to consider that using both anterior and posterior portals, most osteochondral lesions can be well treated with a patient in the supine position...

OBJECTIVES: This study examined the existence of a threshold level (proficiency barrier) of actual motor competence (MC) below which a child is not likely to attain 60min of moderate-to-vigorous physical activity (MVPA) per day. DESIGN: A cross-sectional study. METHODS: Actual MC was assessed in 326 children (48.5% boys; age=9.50±1.24years) using the Test of Gross Motor Development-2; MVPA was measured with ActiGraph GT3X+accelerometers. Perceived MC, included as a potential mediating variable, was assessed with the Self-Perception Profile for Children...

Surgeons should understand the anatomic, vascular, biomechanical, and predisposing factors related to lateral ankle instability and peroneal tendon injuries, including peroneal tendinitis and tenosynovitis, peroneal tendon tears and ruptures, as well as peroneal tendon subluxation and dislocation. Surgeons should understand the treatment options and recommendations for patients who have lateral ankle instability and peroneal tendon injuries from the perspective of a sports medicine foot and ankle specialist...

BACKGROUND: In recent years, the number of total ankle arthroplasty procedures performed has increased dramatically. We sought to report the clinical results of the largest cohort of patients treated with a modern fixed-bearing total ankle arthroplasty by a single surgeon. METHODS: We retrospectively reviewed the charts of 78 consecutive patients (81 ankles) who underwent total ankle arthroplasty with a minimum clinical follow-up of 2 years. Sixty-three patients completed standardized questionnaires including the Foot and Ankle Disability Index (FADI), the Short Musculoskeletal Function Assessment (SMFA), the Short Form (SF)-36v2, and a visual analog scale (VAS) for pain...

BACKGROUND: The critical lesion size treated with bone marrow stimulation (BMS) for osteochondral lesions of the talus (OLTs) has been 150 mm2 in area or 15 mm in diameter. However, recent investigations have failed to detect a significant correlation between the lesion size and clinical outcomes after BMS for OLTs. PURPOSE: To systematically review clinical studies reporting both the lesion size and clinical outcomes after BMS for OLTs. STUDY DESIGN: Systematic review...
