Generation of broadband airborne ultrasound using an Harmonic Acoustic Pneumatic Source.

This paper presents a new type of airborne transducer for generating broadband ultrasound with a high Sound Pressure Level (SPL). The concept is based on the Harmonic Acoustic Pneumatic Source (HAPS) that uses pressurized air in conjunction with a flow chopper made up of a rotating cage with slots connected to a specific exhaust. The fundamental frequency depends on the number of slots and the rotation speed of the cage.

High-level judo practice after hip resurfacing.

Background And Hypothesis: The ability to participate in sports after hip arthroplasty is increasingly being requested by patients. The possibilities of participating in sports such as judo after hip arthroplasty have not been explored sufficiently even though these sports are associated with a high risk of loosening, dislocation or revision. The aim of this study was to evaluate the return to judo after hip resurfacing arthroplasty (HRA) in terms of time and level of practice in an expert population and to determine the surgical complication rate.

Very long-term osteoarthritis rate after anterior cruciate ligament reconstruction: 182 cases with 22-year' follow-up.

Background: Few data are available on the 20-year outcomes of anterior cruciate ligament (ACL) reconstruction. The purpose of this study was to assess the prevalence and risk factors of knee osteoarthritis at least 20 years after ACL reconstruction.

Hypothesis: Factors associated with progression to knee osteoarthritis include meniscal lesions, level of physical activity, injury-to-surgery time, body mass index, residual laxity, tunnel position and cartilage injury.

Complications After Anterior Cruciate Ligament Reconstruction and Their Relation to the Type of Graft: A Prospective Study of 958 Cases.

Background: Complications and adverse events after anterior cruciate ligament (ACL) reconstruction are well known, but they have been underestimated in previous studies.

Purpose: To describe the complications and adverse events after ACL reconstruction within a 2-year follow-up and analyze them in relation to the type of graft.

Study Design: Cohort study; Level of evidence, 3.

Epidemiology of Judo-Related Injuries in 21 Seasons of Competitions in France: A Prospective Study of Relevant Traumatic Injuries.

Background: Judo is a full-contact fighting sport that may lead to severe injuries. There are limited data available on the incidence of judo-related injuries. The French Judo Federation has established a surveillance system to document the frequency and type of injuries during judo competitions.

Long-Term Results for Treatment of Chronic Ankle Instability With Fibular Periosteum Ligamentoplasty and Extensor Retinaculum Flap.

Long-term results of anatomic reconstruction for chronic ankle instability are good, but no study has shown the results of fibular periosteum ligamentoplasty associated with extensor retinaculum flap at long-term follow-up. To demonstrate the efficacy of fibular periosteum ligamentoplasty and extensor retinaculum flap in chronic lateral instability, 40 patients underwent surgery for ankle instability. Thirty-three (82.

Functional outcomes and return to sports after surgical treatment of insertional Achilles tendinopathy: Surgical approach tailored to the degree of tendon involvement.

Introduction: Insertional Achilles tendinopathy is a generic term that encompasses several types of ailments. While conservative treatment is less effective than for conditions isolated to the tendon body, there is no consensus as to the best type of surgical care.

Hypothesis: Surgical treatment for insertional Achilles tendinopathy that is tailored to the severity of the tendon involvement will lead to satisfactory functional outcomes.

[Management of shoulder instability].

Management of shoulder instability. Shoulder instability is a commonly encountered problem in young active athletes. Instability is most often due to a traumatic gleno-humeral dislocation.

Spontaneous Knee Ankylosis through Heterotopic Ossification after Total Knee Arthroplasty.

This paper reports on a case of total ankylosis of the knee after a cruciate-sacrificing cemented total knee arthroplasty (TKA). An 82-year-old female patient previously underwent primary TKA for osteoarthritis twenty years ago in our institution. She had recovered uneventfully and returned to her regular activities.

Recurrent posterior knee laxity: diagnosis, technical aspects and treatment algorithm.

Purpose: Aim of this study was to determine the characteristics, clinical and radiological diagnostic methods of PCL isolated and combined knee injuries.

Methods: One hundred and twelve patients with a recurrent posterior knee laxity were surgically treated. Clinical examination, MRI, Telos™ stress dynamic X-rays, KT-1000 measurements and the IKDC questionnaire were used to diagnose and evaluate these injuries.

Graft position and fusion rate following arthroscopic Latarjet.

Purpose: The arthroscopic Latarjet procedure is recently becoming an increasingly popular technique. Nevertheless, position and fusion of the autograft had not been well studied yet. The purpose of this study was to assess the positioning of the coracoid graft and the fusion rate on CT scan in the arthroscopic Latarjet procedure.

Injuries in judo: a systematic literature review including suggestions for prevention.

Background: There is limited knowledge on epidemiological injury data in judo.

Objective: To systematically review scientific literature on the frequency and characteristics of injuries in judo.

Methods: The available literature up to June 2013 was searched for prospective as well as retrospective studies on injuries in judo.
