Effectiveness of Protective Measures and Rules in Reducing the Incidence of Injuries in Combat Sports: A Scoping Review.

In recent years, much effort has been made to reduce the injury rate in combat sports. However, the question remains to what extent these measures are effective. Analysis of studies could provide evidence of the effectiveness of measures aimed at reducing the incidence of injuries.

Karatekas educated on injury prevention and supported by fitness coaches are more likely to practise injury prevention.

To determine the current perceptions and practices of top-level karate athletes concerning risk factors and injury prevention programme (IPP) implementation in training and competition. Out of 90 eligible countries (933 athletes) participating in the karate World Senior Championships (WSC) in Madrid 2018, 50 countries (55.6%) represented by 137 athletes (14.

Severe knee injuries among karate athletes ranking towards the Tokyo Olympic Games: a retrospective study.

Background: Injury prevention strategies should be built upon data about the more frequent injuries in each specific sport. Therefore, this study aimed to describe the lifetime prevalence and characteristics of severe knee injuries among world-class karatekas.

Methods: A retrospective study based on a face-to-face survey was conducted.

Epidemiology of injuries in Olympic-style karate competitions: systematic review and meta-analysis.

Objective: To report the epidemiology of injuries in Olympic-style karate competitions.

Design: Systematic review and meta-analysis. Pooled estimates of injury incidence rates per 1000 athlete-exposures (IIR) and per 1000 min of exposure (IIR) were obtained by fitting random-effects models.

Quadriceps tendon autograft and platelet rich plasma injection to treat chronic Achilles tears-a minimum two-year follow-up.

Background: The possibility of using a bone-tendon quadriceps tendon graft and platelet rich plasma (PRP) injection to enhance healing capability, to solve the defect created by stump retraction in chronic Achilles tendon ruptures was studied in a series of 8 patients.

Methods: A series of 8 patients studied prospectively and followed for more than 24 months is presented. Results were evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) score, and evaluating pain, level of activity, footwear restrictions, and satisfaction.

Time-Loss Injuries in Karate: A Prospective Cohort Study of 4 Consecutive World Karate Championships.

Background: Prospective studies on injuries in martial arts competitions are scarce, especially those involving time-loss injuries. The upsurge of karate athletes competing in top-level karate competitions warrants elucidation of the time-loss injury risk.

Purpose: To determine the time-loss injury proportion and incidence rate, describe the injury pattern among elite senior karate athletes, and compare the risk of time-loss injuries in male versus female athletes and in individual (ie, weight categories) versus team competitions (free-weight category).

Osteoarthritis in Spain: A nationwide survey of medical specialists.

Objective: To determine the reality of the resources and care needs in Spain for the management of patients with osteoarthritis.

Materials And Method: An online survey.

Results: Description of 190 responses to a structured questionnaire (141 orthopedic surgeons and 49 rheumatologists).

Epidemiology of injuries in juniors participating in top-level karate competition: a prospective cohort study.

Background: Karate is a popular combat semi-contact sport among juniors, but there are only few studies available on the epidemiology of injuries in karate junior athletes.

Aim: The aims of this study were to determine the incidence and pattern of injuries in top-level karate competition for athletes aged 16 to 20 years, and to compare injury rates between age groups (ie, under 18-year-old [U18] and under 21-year-old [U21]) and genders, following the introduction of new weight categories.

Methods: A prospective injury surveillance was undertaken at four consecutive World Karate Championships (2009 to 2015), following the same protocols used in previous investigations.

Injuries of the obturator muscles in professional soccer players.

Purpose: Obturator externus and internus muscular tears are uncommon injuries. Only a few case reports exist, mainly in high-level athletes. Our aim is to describe a series of obturator externus and internus muscular tears in professional soccer players.

Low risk of concussions in top-level karate competition.

Background: Although it is well known that injuries occur in combat sports, the true incidence of concussions is not clearly defined in the literature for karate competition.

Aim: To determine the incidence of concussions in top-level (World Karate Federation World Championships) karate competition.

Methods: Injuries that took place in 4 consecutive World Karate Championships (from 2008 to 2014) were prospectively registered.

Quadriceps autograft to treat Achilles Chronic tears: a simple surgical technique.

Background: Chronic Achilles tendon tears could hinder patients and represent a challenge to surgeons. Although many different surgical techniques have been proposed for reconstruction of a neglected Achilles tendon rupture, there is no clear evidence to support one technique over the others, but the use of a technique that could allow for an "anatomical" reconstructions seems desirable.

Methods: The present paper describes a new anatomic Achilles tendon reconstruction for chronic tears, using a quadriceps tendon autograft as graft source, with PRP injected into the graft and the neighbor tissue, and fixation in a bone trough with a simple small fragments screw.

Low Risk of Injuries in Young Adolescents Participating in Top-Level Karate Competition.

Background: Prospective studies on injuries in martial arts competition are scarce, especially those involving young practitioners, but the upsurge of children and adolescents taking part in organized training and competition in these sports requires clarification of the injury risk that they represent for youths.

Hypothesis: Top-level karate competition for young adolescents (cadets, or 14- to 15-year-olds) has a low injury rate and can be safely promoted.

Study Design: Descriptive epidemiological study.

Arthroscopic reduction of a chronically dislocated reversed shoulder arthroplasty.

We present the case of a 64-year-old female patient who had a traumatic dislocation of a reversed shoulder arthroplasty that was unnoticed for 5 weeks and that was reduced arthroscopically. Arthroscopy of the shoulder, as in other joints with prostheses, can facilitate the treatment of conditions that would otherwise require the use of open surgery to solve them and that might become more frequent because of the widespread use of reversed shoulder arthroplasties, which have a high rate of dislocation.

The injury profile of Karate World Championships: new rules, less injuries.

The aim of this paper is to document the injury rate in high-level modern competitive karate after a change of competition rules was implemented in the year 2000, and to compare it with the injury rate found before the rules were changed. A prospective recording of the injuries resulting from 2,762 matches in three consecutive World Karate Championships (representing 7,425 min of active fighting) was performed, and compared with the results from 2,837 matches from the three last World Karate Championships (representing 7,631 min of active fighting) held before the change of competition rules. In total, 497 injuries were recorded, with an incidence of 0.

Stress fractures of the femur after ACL reconstruction with transfemoral fixation.

The ACL reconstruction with hamstring tendons has become increasingly popular, in part because it is assumed that the complication rate associated with the technique and their severity are lower than with patellar tendon. Two cases of stress reaction of the medial supracondylar area of the femur after ACL reconstruction with hamstring tendons using BioTransfix (Arthrex, Naples, FL, USA) devices for fixation within femur are presented. Both patients were professional athletes (one soccer and one basketball player), and it is hypothesized that the accelerated rehabilitation program used might have represented a risk factor for stress fractures when associated with the guide pin exit hole in the medial femoral cortex.

Injury profile in competitive karate: prospective analysis of three consecutive World Karate Championships.

The goal of this paper was to document the injury rate in modern competitive karate. A prospective recording of the injuries resulting from 2,837 matches in three consecutive World Karate Championships (WKC) was performed. Eight hundred and ninety-one injuries were recorded, with an incidence of 0.
