In recent years, minimally invasive surgery has developed and progressed the standard of care in orthopaedics and sports medicine. In particular, the use of posterior hindfoot arthroscopy in the treatment of posterior ankle and hindfoot injury is increasing rapidly as a means of reducing pain, infection rates, and blood loss postoperatively compared with traditional open procedures. In athletes, hindfoot arthroscopy has been used effectively in expediting rehabilitation and ultimately in minimizing the time lost from competition at previous levels. Van Dijk et al were the first to describe the original 2-portal technique, which remains the most commonly used by surgeons today and forms the basis for this review. The current evidence in the literature supports the use of 2-portal hindfoot arthroscopy as a safe, primary treatment strategy for symptoms of posterior ankle impingement, including resection of os trigonum, treatment of flexor hallucis longus and peroneal tendon injury, treatment of osteochondral lesions of the ankle, and the resection of subtalar coalitions. In this review, we present where possible an evidence-based literature review on the arthroscopic treatment of posterior ankle and hindfoot abnormalities. Causes, diagnosis, surgical technique, outcomes, and complications are each discussed in turn.
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.MethodsA 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.ResultsThe 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).ConclusionThe 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 evidenceDiagnostic study, Level I.Electronic supplementary materialThe online version of this article (doi:10.1007/s00167-016-4242-7) contains supplementary material, which is available to authorized users.

Objective To assess the mortality risk in subsequent years (adjusted for year of birth, nationality, and sex) of former Olympic athletes from disciplines with different levels of exercise intensity.Design Retrospective cohort study. Setting Former Olympic athletes.Participants 9889 athletes (with a known age at death) who participated in the Olympic Games between 1896 and 1936, representing 43 types of disciplines with different levels of cardiovascular, static, and dynamic intensity exercise; high or low risk of bodily collision; and different levels of physical contact. Main outcome measure All cause mortality.Results Hazard ratios for mortality among athletes from disciplines with moderate cardiovascular intensity (1.01, 95% confidence interval 0.96 to 1.07) or high cardiovascular intensity (0.98, 0.92 to 1.04) were similar to those in athletes from disciplines with low cardiovascular intensity. The underlying static and dynamic components in exercise intensity showed similar non-significant results. Increased mortality was seen among athletes from disciplines with a high risk of bodily collision (hazard ratio 1.11, 1.06 to 1.15) and with high levels of physical contact (1.16, 1.11 to 1.22). In a multivariate analysis, the effect of high cardiovascular intensity remained similar (hazard ratio 1.05, 0.89 to 1.25); the increased mortality associated with high physical contact persisted (hazard ratio 1.13, 1.06 to 1.21), but that for bodily collision became non-significant (1.03, 0.98 to 1.09) as a consequence of its close relation with physical contact.Conclusions Among former Olympic athletes, engagement in disciplines with high intensity exercise did not bring a survival benefit compared with disciplines with low intensity exercise. Those who engaged in disciplines with high levels of physical contact had higher mortality than other Olympians later in life.
PurposeThe aim of this study was to systematically evaluate the available literature on surgical treatment for midportion Achilles tendinopathy and to provide an overview of the different surgical techniques.MethodsA systematic review of the literature available in MEDLINE, EMBASE and the Cochrane database of controlled trials was performed. The primary outcome measure in terms of patient satisfaction and the secondary outcome measures that consisted of complication rate, pain score, functional outcome score and success rate were evaluated. The Downs & Black checklist and the Coleman methodology scale were used to assess the methodological quality of included articles.ResultsOf 1090 reviewed articles, 23 met the inclusion criteria. The included studies reported on the results of 1285 procedures in 1177 patients. The surgical techniques were divided into five categories. Eleven studies evaluated open surgical debridement, seven studies described minimally invasive procedures, three studies evaluated endoscopic procedures, one study evaluated open gastrocnemius lengthening, and one study reported on open autologous tendon transfer. Results regarding patient satisfaction (69–100 %) and complication rate (0–85.7 %) varied widely.ConclusionsThis study demonstrates the large variation in surgical techniques available for treatment of midportion Achilles tendinopathy. None of the included studies compared surgical intervention with nonsurgical or placebo intervention. Minimally invasive and endoscopic procedures yield lower complication rates with similar patient satisfaction in comparison with open procedures. Minimally invasive and endoscopic procedures might therefore prove to be the future of surgical treatment of Achilles midportion tendinopathy.Level of evidenceIV.
