PURPOSE: Patient-reported outcome measures (PROMs) have become a cornerstone for the evaluation of the effectiveness of treatment. The Achilles tendon Total Rupture Score (ATRS) is a PROM for outcome and assessment of an Achilles tendon rupture. The aim of this study was to translate the ATRS to Dutch and evaluate its reliability and validity in the Dutch population.
METHODS: A forward-backward translation procedure was performed according to the guidelines of cross-cultural adaptation process. The Dutch ATRS was evaluated for reliability and validity in patients treated for a total Achilles tendon rupture from 1 January 2012 to 31 December 2014 in one teaching hospital and one academic hospital. Reliability was assessed by the intraclass correlation coefficients (ICC), Cronbach's alpha and minimal detectable change (MDC). We assessed construct validity by calculation of Spearman's rho correlation coefficient with domains of the Foot and Ankle Outcome Score (FAOS), Victorian Institute of Sports Assessment-Achilles questionnaire (VISA-A) and Numeric Rating Scale (NRS) for pain in rest and during running.
RESULTS: The Dutch ATRS had a good test-retest reliability (ICC = 0.852) and a high internal consistency (Cronbach's alpha = 0.96). MDC was 30.2 at individual level and 3.5 at group level. Construct validity was supported by 75 % of the hypothesized correlations. The Dutch ATRS had a strong correlation with NRS for pain during running (r = -0.746) and all the five subscales of the Dutch FAOS (r = 0.724-0.867). There was a moderate correlation with the VISA-A-NL (r = 0.691) and NRS for pain in rest (r = -0.580).
CONCLUSION: The Dutch ATRS shows an adequate reliability and validity and can be used in the Dutch population for measuring the outcome of treatment of a total Achilles tendon rupture and for research purposes.
LEVEL OF EVIDENCE: Diagnostic study, Level I.
The 16th Amsterdam Foot and Ankle Course and the 2nd Advanced Amsterdam Foot and Ankle Course are coming up soon. From 22nd -24th of June 2016, we will be happy to turn the Academic Medical Center Amsterdam into a course venue full of Cadaver Lab sessions, Lectures, Computer courses, Live surgery and much more. The faculty is ready and the preparations are in full swing. We are looking forward to have you in Amsterdam, the Netherlands.
This year the Teach the Teacher course is held from 26-28 May in ASTC, National University Hospital, Singapore. The course is an intensive three day event to include lectures, debates and Cadaver workshops made possible by smith&nephew. The objective of the program is to build a group of connected surgeons dedicated to ankle arthroscopy. These surgeons are the (future) leaders in this field in their countries. The faculty for the course consists of Prof. Niek van Dijk, prof Jean Brilhault, prof Xu Dong MIAO and prof. Zhong Ming SHI.
The cycle for science tour Amsterdam - Barcelona 2016 is a fact! Cycling for science, in the defense of life. We will ride from Amsterdam to Barcelona and you are all invited to join!
The goal of this project is to raise funds to support research in the field of orthopedic sport medicine with focus on prevention of disease. The tour consists of eight stages, which brings the participants from the 2014 ESSKA hosting city, Amsterdam, to the 17th biannual ESSKA congress in Barcelona. During the tour in each city there will be a symposium with renowned speakers, charity dinners and auctions. Are you in?

Understanding the anatomy of the ankle ligaments is important for correct diagnosis and treatment. Ankle ligament injury is the most frequent cause of acute ankle pain. Chronic ankle pain often finds its cause in laxity of one of the ankle ligaments. In this pictorial essay, the ligaments around the ankle are grouped, depending on their anatomic orientation, and each of the ankle ligaments is discussed in detail.

Identification of the superficial peroneal nerve : Anatomical study with surgical implications.
de Leeuw PA, Golanó P, Blankevoort L, Sierevelt IN, van Dijk CN.
PURPOSE:To prevent iatrogenic damage to the superficial peroneal nerve during ankle arthroscopy, it needs to be identified. The purpose of the present study was to determine which clinical test identified the superficial peroneal nerve most frequently and which determinants negatively affected the identification.
METHODS:A total of 198 ankles (99 volunteers) were examined for identification of the superficial peroneal nerve. Race, gender, body mass index (BMI), shoe size and frequency of physical activity were collected.
RESULTS:The best method to identify the superficial peroneal nerve was the maximal combined ankle plantar flexion and inversion test. In this position, the nerve was identified in 57 % of the ankles by palpation. BMI was the only independently influential factor in the identification of the superficial peroneal nerve.
CONCLUSION:Since in nearly six out of the ten ankles the superficial peroneal nerve can be identified, it is advised to assess its anatomy prior to portal placement. A higher BMI negatively influences the identification of the superficial peroneal nerve.

Anatomy of the inferior extensor retinaculum and its role in lateral ankle ligament reconstruction: a pictorial essay.
Dalmau-Pastor M, Yasui Y, Calder JD, Karlsson J, Kerkhoffs GM, Kennedy JG.
The inferior extensor retinaculum (IER) is an aponeurotic structure, which is in continuation with the anterior part of the sural fascia. The IER has often been used to augment the reconstruction of the lateral ankle ligaments, for instance in the Broström-Gould procedure, with good outcomes reported. However, its anatomy has not been described in detail and only a few studies are available on this structure. The presence of a non-constant oblique supero-lateral band appears to be important. This structure defines whether the augmentation of the lateral ankle ligaments reconstruction is performed using true IER or only the anterior part of the sural fascia. It is concluded that the use of this structure will have an impact on the resulting ankle stability.
Our department received the accreditation as IOC Research Centerfor Prevention of Injury and Protection of Athlete Health. Only nine centers worldwide received this recognition. The IOC has chosen our Amsterdam Collaboration on Health & Safety in Sports (ACHSS), because we stand at the forefront of the sports medicine research. The ACHSS brings together the two teaching hospitals in Amsterdam, combining the two Dutch leading groups on research and practice on prevention and treatment in sports medicine. Within the ACHSS research focuses on the prevention and treatment of sports injuries in Olympic athletes in the broadest sense. We were honoured to receive the accreditation from professor Lars Engebretsen, head of the International Olympic Committee medical research.
