This is the first study of a homogeneous cohort of sports people which does not include sedentary patients with comorbidity that caused tendinopathy.</p><p id="par0195" class="elsevierStylePara elsevierViewall">Although there is now no set protocol for the treatment of Achilles tendinopathy, almost all authors defend commencing with conservative treatment. Some authors such as Alfredson et al.<a class="elsevierStyleCrossRef" href="#bib0260"><span class="elsevierStyleSup">19</span></a> have proposed non-surgical treatment algorithms. Nevertheless, as they mix sedentary patients with others who do sports this may reduce the external validity of their studies.</p><p id="par0200" class="elsevierStylePara elsevierViewall">The conservative treatments best supported by findings are eccentric exercises,<a class="elsevierStyleCrossRef" href="#bib0170"><span class="elsevierStyleSup">1</span></a> which are widely used in Scandinavian countries. They involve specific programmes lasting for several weeks or months, and their initial results were very hopeful. However, more recent trials comparing some of these therapies with gentle non-systematic exercises either found no differences or far less optimistic results.<a class="elsevierStyleCrossRef" href="#bib0265"><span class="elsevierStyleSup">20</span></a> On the other hand, patient compliance with long-term daily exercises achieves a low level of adherence to the treatment.</p><p id="par0205" class="elsevierStylePara elsevierViewall">Together with eccentric exercises, shockwaves are the conservative therapy that is best supported by the evidence. They act in three ways, by promoting collagen synthesis, destroying amyelinic fibres and hollowing out interstitial tissue. All of this will activate scarring mechanisms. A recent meta-analysis states that this technique is effective after 3 months in refractory non-insertional tendinopathy.<a class="elsevierStyleCrossRef" href="#bib0270"><span class="elsevierStyleSup">21</span></a></p><p id="par0210" class="elsevierStylePara elsevierViewall">Respecting pharmacological treatments, the use of NSAIDs is contraindicated by almost all authors. This is because they interfere with cell repair mechanisms, and some studies prove that inflammatory molecules such as prostaglandins are not present in this entity.<a class="elsevierStyleCrossRef" href="#bib0275"><span class="elsevierStyleSup">22</span></a></p><p id="par0215" class="elsevierStylePara elsevierViewall">In the same way that NSAIDs do not seem to be useful, corticoid peritendon injections have not been shown to be effective in this condition, although they are for acute peritendonitis. As is the case for all tendons, injections into this tendon must be avoided due to their catabolic effects. Unlike NSAIDs, cryotherapy has been shown to reduce metabolic needs as well as two thirds of capillary flow, which in neovascularisation means reducing the extravasation of proteins that prolong pathogenesis.<a class="elsevierStyleCrossRef" href="#bib0185"><span class="elsevierStyleSup">4</span></a></p><p id="par0220" class="elsevierStylePara elsevierViewall">Some articles with a high level of evidence have been published that state that there are no significant differences between the use of platelet-rich plasma and a placebo.<a class="elsevierStyleCrossRef" href="#bib0280"><span class="elsevierStyleSup">23</span></a> Nevertheless, other studies have obtained good results with the use of platelet-rich plasma in patients with non-insertional Achilles tendinopathy, without distinguishing subgroups according to their sports activity.<a class="elsevierStyleCrossRef" href="#bib0285"><span class="elsevierStyleSup">24</span></a></p><p id="par0225" class="elsevierStylePara elsevierViewall">There are factors which have been shown to predispose runners to tendinopathy.<a class="elsevierStyleCrossRef" href="#bib0290"><span class="elsevierStyleSup">25</span></a> These include footwear, training on hard surfaces, lateral instability of the ankle and high arches, and special attention should be paid to these. This is why before indicating surgery we study and modify training habits as a fundamental part of the conservative treatment of our cohort.</p><p id="par0230" class="elsevierStylePara elsevierViewall">According to the majority of publications conservative techniques as a whole are successful in approximately 2/3 of patients. Many works cite permanent changes of activity, based mainly on replacing running with some other type of activity, without which they would probably not achieve such high success rates. On the other hand the results of conservative treatment have been shown to be highly unpredictable in cases which evolved over several months.<a class="elsevierStyleCrossRef" href="#bib0295"><span class="elsevierStyleSup">26</span></a></p><p id="par0235" class="elsevierStylePara elsevierViewall">We did not find the same success rates in our experience, given that our patients did not consider ceasing to run or definitively changing their activity as a treatment options.</p><p id="par0240" class="elsevierStylePara elsevierViewall">All of the patients in the series presented tendinopathy that was refractory to combined conservative treatment under our supervision. Other previous conservative treatments which they may have followed without our indication were not taken into account.</p><p id="par0245" class="elsevierStylePara elsevierViewall">Respecting surgical treatment, the majority of authors agree that it should be used in the 25–35% of patients who do not improve with conservative treatments. They state that a waiting time of at least 6 months should be allowed before considering surgery.<a class="elsevierStyleCrossRefs" href="#bib0170"><span class="elsevierStyleSup">1,3</span></a> It is here that patients of our type usually invest a large amount of time and money in seeking a solution, without finding a standard surgical option.</p><p id="par0250" class="elsevierStylePara elsevierViewall">Surgery aims on the one hand to reactivate or at least stimulate the intrinsic repair mechanisms which failed in conservative options. There are a range of techniques to do this. One example is to make longitudinal incisions, which classically has been taken to be a procedure that promotes the recovery of normal tendon structure; nevertheless, no articles prove that this brings about a clinical improvement.</p><p id="par0255" class="elsevierStylePara elsevierViewall">The other fundamental surgical procedure is the stripping of fibrotic adhesions as well as anomalous vessels and aberrant nerve fibres. Van Dijk et al.<a class="elsevierStyleCrossRef" href="#bib0230"><span class="elsevierStyleSup">13</span></a> consider the cutting of the fibres that colonise the tendon from the paratendon to be the objective of treatment using endoscopic technique, without acting on the degenerate tendon itself. There are also other adhesiolysis techniques described by Mafulli et al., such as the ultrasound-guided injection of large volumes of serum into the pre-Achilles zone<a class="elsevierStyleCrossRef" href="#bib0300"><span class="elsevierStyleSup">27</span></a> and adhesiolysis by passing Ethibond thread through longitudinal incisions in the tendon (stripping technique).<a class="elsevierStyleCrossRef" href="#bib0305"><span class="elsevierStyleSup">28</span></a></p><p id="par0260" class="elsevierStylePara elsevierViewall">The use of percutaneous radiofrequency has been described for insertional Achilles tendinopathy,<a class="elsevierStyleCrossRef" href="#bib0310"><span class="elsevierStyleSup">29</span></a> and while this may improve tissue repair, it will not act on peritendon fibrotic adhesions and neovascularisation.</p><p id="par0265" class="elsevierStylePara elsevierViewall">The proximal freeing of the gastrocnemius gives good results in sedentary patients, in whom the postoperative strength of the leg operated does not differ from its preoperative strength;<a class="elsevierStyleCrossRef" href="#bib0315"><span class="elsevierStyleSup">30</span></a> however, this may not be the most suitable technique for patients who do sports, given the possibility that the operated leg may lose the strength necessary for running in comparison with the healthy leg.</p><p id="par0270" class="elsevierStylePara elsevierViewall">To try to improve Achilles tendon mechanics after cutting the peritendon pathological tissues, some authors recently suggested lengthening the tendon using the hallucis longus flexor,<a class="elsevierStyleCrossRef" href="#bib0320"><span class="elsevierStyleSup">31</span></a> and this may require a subsequent change of activity.</p><p id="par0275" class="elsevierStylePara elsevierViewall">We believe that in patients who are going to demand a high level of mechanical performance, as is the case in our cohort, surgical treatment firstly requires the stripping of all pathological tissue from around the tendon. Doppler ultrasound will show a high increase in vascular flow in the tendon which should not be visible in normal tendons.<a class="elsevierStyleCrossRef" href="#bib0325"><span class="elsevierStyleSup">32</span></a> This vascularisation will be what we strip away in the first phase of the operation.</p><p id="par0280" class="elsevierStylePara elsevierViewall">We then act on the tendon itself, activating its overwhelmed repair mechanisms. We use bipolar radiofrequency for this. This technique was first used to treat myocardial ischaemia, in which coblation showed an increase in functional vascularisation.<a class="elsevierStyleCrossRef" href="#bib0330"><span class="elsevierStyleSup">33</span></a> The terminal used applies a saline serum that spreads over the tissue at a speed that can be adjusted, which when it makes contact with the electrode creates a jet of steam that consists of an ion-charged plasma field that dries the tissues. Its main advantage vs electrocoagulation is that it acts at physiological temperatures, and its field of action can be adjusted, thereby reducing iatrogenic damage to adjacent structures. This technique is highly reproducible, given the absence of a long learning curve. It is safe due to the small amount of tissue that is dried and the fact that it always occurs at a physiological temperature.</p><p id="par0285" class="elsevierStylePara elsevierViewall">Careful follow-up is as important as appropriate surgical treatment, given that the symptoms may take some time to disappear. During this time it is of fundamental importance for our patient profile to keep fit, so that they will have to perform activities other than running while gradually increasing the intensity at which the operated tendon works.</p><p id="par0290" class="elsevierStylePara elsevierViewall">To conclude, we may say that non-insertional Achilles tendinopathy is an entity that is becoming more common in visits to sports injury clinics due to the increasing popularity of running. Although conservative treatment should be the first choice, specific aspects of highly demanding patients have to be taken into account. If conservative treatment fails, microstripping and coblation of the calcaneus tendon in sportsmen and women is a safe and reproducible technique. It achieves a high rate of return to symptom-free activity as well as to the previous level of sport performance.</p></span><span id="sec0025" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0085">Ethical disclosures</span><span id="sec0030" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0090">Protection of human and animal subjects</span><p id="par0295" class="elsevierStylePara elsevierViewall">The authors declare that the procedures followed comply with the ethical regulations of the corresponding human experimentation committee, the World Medical Association and the Helsinki declaration.</p></span><span id="sec0035" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0095">Confidentiality of data</span><p id="par0300" class="elsevierStylePara elsevierViewall">The authors declare that they followed the protocols of their hospital on the publication of patient data.</p></span><span id="sec0040" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0100">Right to privacy and informed consent</span><p id="par0305" class="elsevierStylePara elsevierViewall">The authors have obtained the informed consent of the patients and/or subjects referred to in the article.
