J Orthop Surg Res 2024; 19:132. [PMID: 38341569 PMCID: PMC10858558 DOI: 10.1186/s13018-024-04559-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Accepted: 01/11/2024] [Indexed: 02/12/2024] Open
Abstract
BACKGROUND Chronic Achilles tendon ruptures (CATR) often require surgical intervention to restore function. Despite numerous treatment modalities available, the optimal management strategy remains controversial given the limited high-quality evidence available. This article aims to provide evidence-based guidelines for the surgical management of CATR through a comprehensive systematic review of the available data. The consensus reached by synthesizing the findings will assist clinicians in making informed decisions and improving patient outcomes. METHODS A group of 9 foot surgeons in three continents was consulted to gather their expertise on guidelines regarding the surgical management of CATR. Following the proposal of 9 clinical topics, a thorough and comprehensive search of relevant literature published since 1980 was conducted for each topic using electronic databases, including PubMed, MEDLINE, and Cochrane Library, to identify relevant studies published until 1 October 2023. All authors collaborated in drafting, discussing, and finalizing the recommendations and statements. The recommendations were then categorized into two grades: grade a (strong) and grade b (weak), following the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) concept. Additionally, feedback from 21 external specialists, who were independent from the authors, was taken into account to further refine and finalize the clinical guidelines. RESULTS Nine statements and guidelines were completed regarding surgical indications, surgical strategies, and postoperative rehabilitation protocol. CONCLUSION Based on the findings of the systematic review, this guideline provides recommendations for the surgical management of CATR. We are confident that this guideline will serve as a valuable resource for physicians when making decisions regarding the surgical treatment of patients with CATR.

Abstract
The Gaelic sports of hurling and football, native to Ireland, are increasing in popularity worldwide. The injury profile of these sports requires multidisciplinary management by sports physicians, orthopaedic surgeons, and musculoskeletal (MSK) radiologists, among others. Advances in imaging modalities and interventional techniques have aided the diagnosis and treatment of sport injuries. In this article, we review the literature and our own institutional experience to describe common injury patterns identified in Gaelic games athletes, their main imaging features and relevant therapeutic interventions. We discuss the increasing prevalence of imaging services at sporting events and the central role of MSK radiologists in sports injury management.

Abstract
BACKGROUND The absence of a single, identifiable traumatic cause has been traditionally used as a definition for a causative factor of overuse injury. Excessive loading, insufficient recovery, and underpreparedness can increase injury risk by exposing athletes to relatively large changes in load. The musculoskeletal system, if subjected to excessive stress, can suffer from various types of overuse injuries which may affect the bone, muscles, tendons, and ligaments. METHODS We performed a search (up to March 2018) in the PubMed and Scopus electronic databases to identify the available scientific articles about the pathophysiology and the incidence of overuse sport injuries. For the purposes of our review, we used several combinations of the following keywords: overuse, injury, tendon, tendinopathy, stress fracture, stress reaction, and juvenile osteochondritis dissecans. RESULTS Overuse tendinopathy induces in the tendon pain and swelling with associated decreased tolerance to exercise and various types of tendon degeneration. Poor training technique and a variety of risk factors may predispose athletes to stress reactions that may be interpreted as possible precursors of stress fractures. A frequent cause of pain in adolescents is juvenile osteochondritis dissecans (JOCD), which is characterized by delamination and localized necrosis of the subchondral bone, with or without the involvement of articular cartilage. The purpose of this compressive review is to give an overview of overuse injuries in sport by describing the theoretical foundations of these conditions that may predispose to the development of tendinopathy, stress fractures, stress reactions, and juvenile osteochondritis dissecans and the implication that these pathologies may have in their management. CONCLUSIONS Further research is required to improve our knowledge on tendon and bone healing, enabling specific treatment strategies to be developed for the management of overuse injuries.

Abstract
Achilles tendinopathy is a common cause of disability. Despite the economic and social relevance of the problem, the causes and mechanisms of Achilles tendinopathy remain unclear. Tendon vascularity, gastrocnemius-soleus dysfunction, age, sex, body weight and height, pes cavus, and lateral ankle instability are considered common intrinsic factors. The essence of Achilles tendinopathy is a failed healing response, with haphazard proliferation of tenocytes, some evidence of degeneration in tendon cells and disruption of collagen fibers, and subsequent increase in noncollagenous matrix. Tendinopathic tendons have an increased rate of matrix remodeling, leading to a mechanically less stable tendon which is more susceptible to damage. The diagnosis of Achilles tendinopathy is mainly based on a careful history and detailed clinical examination. The latter remains the best diagnostic tool. Over the past few years, various new therapeutic options have been proposed for the management of Achilles tendinopathy. Despite the morbidity associated with Achilles tendinopathy, many of the therapeutic options described and in common use are far from scientifically based. New minimally invasive techniques of stripping of neovessels from the Kager's triangle of the tendo Achillis have been described, and seem to allow faster recovery and accelerated return to sports, rather than open surgery. A genetic component has been implicated in tendinopathies of the Achilles tendon, but these studies are still at their infancy.

Abstract
Children with simultaneous injury to the Achilles tendon and heel skin remain a challenge for clinicians. The purpose of this study is to evaluate a combined surgical procedure involving use of the fascia lata to reconstruct the Achilles tendon, and the posterior tibial artery perforator flap to cover the accompanying heel skin injury.Between February 2010 and February 2013, 8 children (3 females and 5 males) between 3 and 12 years of age, with a median age of 7.5 years, were hospitalized in the First Affiliated Hospital of Shantou University Medical College. All injuries involved damage to an Achilles tendon and heel skin. In all patients, the fascia lata was transplanted to reconstruct the Achilles tendon and the posterior tibial artery perforator flap transplanted to cover the skin injury.Hospitalization was 11 to 15 days (mean 13.5 days). Local necrosis (15% of the area) occurred in 1 flap, but healed after changing dressing. All other flaps survived well. At follow-up after 1 to 2 years, all children had recovered good plantar-flexion and supported their weight while walking. Use of the Arner-Lindholm standard to rate clinical efficacy revealed that of the 8 cases, 6 cases showed excellent recovery and 2 were good, with 0 cases ranking moderate or poor. The excellent and good rate was 100%.Child patients with Achilles tendon injury accompanied by heel skin injury are still a challenge for clinicians. Use of the fascia lata, combined with a posterior tibial artery perforator flap, to reconstruct the Achilles tendon and heel skin for children is a feasible, safe, effective method, faster than other methods for recovery, and should be widely applied in the clinic.

Abstract
Haglund's syndrome is impingement of the retrocalcaneal bursa and Achilles tendon caused by a prominence of the posterosuperior calcaneus. Radiographic measurements are not sensitive or specific for diagnosing Haglund's deformity. Localization of a bone deformity and tendinopathy in the same sagittal section of a magnetic resonance imaging scan can assist with the diagnosis in equivocal cases. The aim of the present cross-sectional study was to determine the prevalence of Haglund's syndrome in patients presenting with Achilles tendinopathy and note any associated findings to determine the criteria for a diagnosis of Haglund's syndrome. We reviewed 40 magnetic resonance imaging scans with Achilles tendinopathy and 19 magnetic resonance imaging scans with Achilles high-grade tears and/or ruptures. Achilles tendinopathy was often in close proximity to the superior aspect of the calcaneal tuberosity, consistent with impingement (67.5%). Patients with Achilles impingement tendinopathy were more often female (p < .04) and were significantly heavier than patients presenting with noninsertional Achilles tendinopathy (p = .014) or Achilles tendon rupture (p = .010). Impingement tendinopathy occurred medially (8 of 20) and centrally (10 of 20) more often than laterally (2 of 20) and was associated with a posterior prominence or hyperconvexity with a loss of calcaneal recess more often than a superior projection (22 of 27 versus 8 of 27; p < .001). Haglund's deformity should be reserved for defining a posterior prominence or hyperconvexity with loss of calcaneal recess because this corresponds with impingement. Achilles impingement tendinopathy might be more appropriate terminology for Haglund's syndrome, because the bone deformity is often subtle. Of the 27 images with Achilles impingement tendinopathy, 10 (37.0%) extended to a location prone to Achilles tendon rupture. Given these findings, insertional and noninsertional Achilles tendinopathy are not mutually exclusive and impingement might be a subtle, unrecognized cause of Achilles tendinopathy and subsequent rupture.

Abstract
Achilles tendon tear is common and increasingly frequent. Magnetic resonance imaging (MRI) is the modality of choice for radiological evaluation. It is accurate to assess the status and integrity of the tendon with well documented features. In this article, the MR findings of a normal Achilles tendon as well as common diseases like insertional and noninsertional tendinosis, chronic tendinosis with marked lengthening, tendon rupture are illustrated. After a torn Achilles tendon receives surgical repair, it undergoes different stages of healing process including inflammatory, reparative and remodeling phases. Acute scar tissue in the surgical bed may share similar MR features of tendon re-rupture especially in the early healing phase because both are T2W hyperintense. The size of the gap may even appear larger than expected on T2W images possibly due to tendon remodeling. Understanding of the healing process in post-operative period may prevent overestimation of tendon gap and misdiagnosis of re-tear. We describe the MR features of the post-operative changes with serial studies in different months after surgery. The MR findings with the highlights of the expected sequential changes in normal healing process are illustrated in different cases. A case with surgical repair on a partial tear of Achilles tendon is also included.

Abstract
BACKGROUND The changing demographics of Achilles tendon rupture (ATR) patients have not fully been investigated. However, there has been a general suspicion that this injury is occurring in an increasingly older population, in terms of mean age. The aim of this study was to objectively show an increase in age in Achilles tendon rupture patients over time. METHODS Published literature on Achilles tendon ruptures was searched for descriptive statistics on the demographics of patients in the studies, specifically mean and median age of Achilles tendon rupture patients, gender ratio, percentage of athletics-related injuries, percentage of smokers, and BMI. Linear regression analyses were performed to determine the trend of patient demographics over time. A Welch one-way ANOVA was carried out to identify any possible differences in data obtained from different types of studies. RESULTS The patient demographics from 142 studies were recorded, with all ATR injuries occurring between the years 1953 and 2014. There was no significant difference in the mean age data reported by varying study types, i.e. randomized controlled trial, cohort study, case series, etc. (P=0.182). There was a statistically significant rise in mean age of ATR patients over time (P<0.0005). There was also a statistically significant drop in percentage of male ATR patients (P=0.02). There is no significant trend for percentage of athletics-related injuries, smoking or BMI. CONCLUSION Since 1953 to present day, the mean age at which ATR occurs has been increasing by at least 0.721 years every five years. In the same time period, the percentage of female study patients with ATR injuries has also been increasing by at least 0.6% every five years. LEVEL OF EVIDENCE Level III; Retrospective cohort study.

Abstract
BACKGROUND Achilles tendinopathy (AT) represents a triad of tendon pain, swelling and impaired performance. Extracorporeal shockwave therapy (ESWT) has been endorsed by the National Institute for Health and Care Excellence (NICE) for refractory AT. This audit investigates the long-term outcomes of patients treated with ESWT for refractory AT. METHODS Forty-six patients treated with ESWT for AT between October 2010 and August 2011 completed visual analogue, satisfaction scores and functional assessment questionnaires over two years. Patients were subdivided into two groups depending on whether their AT was insertional (IAT) or non-insertional (NAT). RESULTS Forty-six patients (mean age 58 years) completed all treatments and full 2 year follow up. There was significant improvement in pain at rest, on activity and of function within both NAT and IAT groups over the two-year period. Satisfaction scores were significant in the NAT group but not in the IAT group. CONCLUSIONS ESWT appears to be of benefit in the long term improvement of pain at rest, on activity and functional outcome in patients with refractory AT. However, subjective patient opinion may not match the perceived clinical outcome observed in this audit in all patients and individuals should be counselled regarding this prior to treatment.

Abstract
Achilles tendon pathology is common and affects athletes and nonathletes alike. The cause is multifactorial and controversial, involving biological, anatomical, and mechanical factors. A variety of conditions characterized by Achilles tendon inflammation and/or degeneration can be clinically and histologically differentiated. These include insertional Achilles tendinopathy, retrocalcaneal bursitis, Achilles paratenonitis, Achilles tendinosis, and Achilles paratenonitis with tendinosis. The mainstay of treatment for all of these diagnoses is nonoperative. There is a large body of evidence addressing treatment of acute and chronic Achilles tendon ruptures; however, controversy remains.

Abstract
BACKGROUND Numerous suturing techniques have been described to treat Achilles tendon ruptures. No prior studies have evaluated frayed tendon ends on construct strength and whether this allows for less extensile exposure. METHODS Forty bovine Achilles tendons were divided into groups: 1 control and 4 experimental. Experimental groups were sectioned with ends frayed longitudinally in 2 mm intervals for 2 cm with no fraying for the control group. Four-stand Krackow sutures were used for repairs with 3 loops in the control group, 2 loops in frayed section for experimental groups, and varying numbers of loops (1-4) in healthy tendon. Samples were tested in loading cells at 100 N and 190 N for 1000 cycles. Gap width and maximum load failure were measured. RESULTS Gapping was <5 mm in controls at 100 N-190 N, significantly lower than experimentals. Greatest gapping occurred in groups with 1-2 loops in healthy tendon (10.9-13.9 mm). Most early catastrophic failures (5/8) occurred in groups with 1-2 loops in healthy tendon. Two failures at 100 N occurred in 1-loop healthy tendons. The least failures occurred in controls (2/8), at 190 N. CONCLUSION Suture loops incorporated into frayed tendon portions predisposed repairs to significantly greater gapping and lower maximal failure forces than 4-strand Krackow repairs in unfrayed tendons. CLINICAL RELEVANCE We cannot recommend attempting more limited exposures with sutures in frayed tendon as this may lead to early repair failure. We provided a physiologic model utilizing frayed tendon ends that resembles in vivo Achilles tendon rupture.

METHODS Biomechanical testing, histological analysis, and bromodeoxyuridine (BrdU) labeling/collagen immunohistochemistry were performed to demonstrate that augmentation of an Achilles tendon rupture site with hypoxic MSCs increases healing capacity compared with normoxic MSCs and controls. Fifty Sprague-Dawley rats were used for the experiments, with 2 rats as the source of bone marrow MSCs. The cut Achilles tendons in the rats were equally divided into 3 groups: hypoxic MSC, normoxic MSC, and nontreated (vehicle control). The uncut tendons served as normal uncut controls. Outcome measures included mechanical testing in 24 rats, histological analysis, and BrdU labeling/collagen immunohistochemistry in another 24 rats. RESULTS The ultimate failure load in the hypoxic MSC group was significantly greater than that in the nontreated or normoxic MSC group at 2 weeks after incision (2.1 N/mm(2) vs 1.1 N/mm(2) or 1.9 N/mm(2), respectively) and at 4 weeks after incision (5.5 N/mm(2) vs 1.7 N/mm(2) or 2.7 N/mm(2), respectively). The ultimate failure load in the hypoxic MSC group at 4 weeks after incision (5.5 N/mm(2)) was close to but still significantly less than that of the uncut tendon (7.2 N/mm(2)). Histological analysis as determined by the semiquantitative Bonar histopathological grading scale revealed that the hypoxic MSC group underwent a significant improvement in Achilles tendon healing both at 2 and 4 weeks when compared with the nontreated or normoxic MSC group via statistical analysis. Immunohistochemistry further demonstrated that the hypoxic and normoxic MSC groups had stronger immunostaining for type I and type III collagen than did the nontreated group both at 2 and 4 weeks after incision. Moreover, BrdU labeling of MSCs before injection further determined the incorporation and retention of transplanted cells at the rupture site. CONCLUSION Transplantation of hypoxic MSCs may be a better and more readily available treatment than normoxic MSCs for Achilles tendon ruptures. CLINICAL RELEVANCE The present study provides evidence that transplantation of hypoxic MSCs may be a promising therapy for the treatment of Achilles tendon ruptures.

Abstract
The Achilles tendon (AT) is the most frequently ruptured tendon in the human body yet the aetiology remains poorly understood. Despite the extensively published literature, controversy still surrounds the optimum treatment of complete rupture. Both non-operative management and percutaneous repair are attractive alternatives to open surgery, which carries the highest complication and cost profile. However, the lack of a universally accepted scoring system has limited any evaluation of treatment options. A typical UK district general hospital treats approximately 3 cases of AT rupture a month. It is therefore important for orthopaedic surgeons to correctly diagnose and treat these injuries with respect to the best current evidence-based practice. In this review article, we discuss the relevant pathophysiology and diagnosis of the ruptured AT and summarize the current evidence for treatment.

Abstract
While useful models have been proposed to predict the mechanical impact of damage in tendon and other soft tissues, the applicability of these models for describing in vivo injury and age-related degeneration has not been investigated. Therefore, the objective of this study was to develop and validate a simple damage model to predict mechanical alterations in mouse patellar tendons after aging, injury, or healing. To characterize baseline properties, uninjured controls at age 150 days were cyclically loaded across three strain levels and five frequencies. For comparison, damage was induced in mature (120 day-old) mice through either injury or aging. Injured mice were sacrificed at three or six weeks after surgery, while aged mice were sacrificed at either 300 or 570 days old. Changes in mechanical properties (relative to baseline) in the three week post-injury group were assessed and used to develop an empirical damage model based on a simple damage parameter related to the equilibrium stress at a prescribed strain (6%). From the derived model, the viscoelastic properties of the 300 day-old, 570 day-old, and six week post-injury groups were accurately predicted. Across testing conditions, nearly all correlations between predicted and measured parameters were statistically significant and coefficients of determination ranged from R² = 0.25 to 0.97. Results suggest that the proposed damage model could exploit simple in vivo mechanical measurements to predict how an injured or aged tendon will respond to complex physiological loading regimens.

Abstract
INTRODUCTION Midportion Achilles tendinopathy (MPT) is a common problem in running athletes. Nevertheless, its etiology is not fully understood, and no valid prognostic criterion to predict the development of MPT could be identified to date. The purpose of the present study, therefore, was to evaluate whether power Doppler ultrasonography (PDU) is a suitable method to identify a predisposition to MPT in yet asymptomatic runners. METHODS At 23 major running events, 634 asymptomatic long-distance runners were tested for Achilles tendon thickness, vascularization, and structural abnormalities using a high-resolution PDU device (Toshiba Aplio SSA-770A/80, 12 MHz). In addition, their medical history and anthropometric data were documented. All subjects were contacted 6 and 12 months later and asked about any new symptoms. The collected anamnestic, anthropometric, and ultrasonographic data were subjected to regression analysis to determine their predictive value concerning the manifestation of midportion Achilles tendon complaints (P < 0.05). RESULTS The highest odds ratio (OR) for manifestation of MPT within 1 yr was found for intratendinous blood flow ("neovascularization," OR = 6.9, P < 0.001). An increased risk was also identified for subjects with a positive history of Achilles tendon complaints (OR = 3.8, P < 0.001). A third relevant parameter, just above the level of significance, was a spindle-shaped thickening of the tendon on PDU (Wald χ2 = 3.42). CONCLUSIONS PDU detection of intratendinous microvessels in the Achilles tendons of healthy runners seems to be a prognostically relevant factor concerning the manifestation of symptomatic MPT. This finding lays the foundation for an early identification of a predisposition to MPT as well as prophylactic intervention in as yet asymptomatic runners.

Abstract
The Achilles tendon is the most injured tendon of athletes in the lower extremities and is the most common tendon to rupture spontaneously. Operative repair provides earlier return to sporting activities and lesser rate of rerupture. The general goal is to attempt anastomosis of the acute ruptured ends; however, delayed ruptures may require more extensive procedures. New surgical approaches, including percutaneous and mini-open techniques, are being introduced to potentially diminish perioperative complications. Advent of early protective range of motion and rehabilitation has shown a potential for earlier return to sporting activities for Achilles ruptures.

Abstract
BACKGROUND Bone marrow cells possess multipotentiality and have been used for several treatments. We hypothesized that bone marrow cells might differentiate into regenerated tendon and that several cytokines within bone marrow cells might accelerate tendon healing. Therefore, we treated Achilles tendon ruptures in a rat model with transplantation of whole bone marrow cells. METHODS Nine F344/Nslc (Fisher) rats were the source of bone marrow cells and mesenchymal stem cells as well as normal Achilles tendons. Eighty-seven Fisher rats were used for the experiments. The rats were divided into three groups: the BMC group (bone marrow cells injected around the tendon), the MSC group (mesenchymal stem cells injected around the tendon), and the non-treated control group (incision only). Outcome measures included mechanical testing, collagen immunohistochemistry, histological analysis, and reverse transcription-polymerase chain reaction to detect expression of transforming growth factor-β (TGF-β) and vascular endothelial growth factor (VEGF). RESULTS The ultimate failure load in the BMC group was significantly greater than that in the non-treated or the MSC group at seven days after incision (3.8 N vs. 0.9 N or 2.1 N, p < 0.016) and at fourteen days after incision (10.2 N vs. 6.1 N or 8.2 N, p < 0.016). The ultimate failure load in the BMC group at twenty-eight days after incision (33.8 N) was the same as that of normal tendon (34.8 N). The BMC group demonstrated stronger staining for type-III collagen at seven days after incision and stronger staining for type-I collagen at twenty-eight days than did the MSC group. Expression of TGF-β and VEGF in the BMC group was significantly increased compared with that in the other groups at four days after incision (TGF-β: 1.6 vs. 1.3 or 0.6, p < 0.01; VEGF: 1.7 vs. 1.1 or 0.9, p < 0.01). CONCLUSIONS Transplantation of whole bone marrow cells may be a better and more readily available treatment for Achilles tendon rupture than cultured mesenchymal stem cells.

Abstract
Achilles tendinopathy has been reported as the most common overuse injury in sports medicine clinics (Clement et al. Am J Sports Med 12: 179-184, 1984). Standard treatment regimens include activity modification, heel lifts, arch supports, stretching exercises, nonsteroidal anti-inflammatories, and eccentric loading. There is a lack of consensus regarding treatment. Even so, most athletes will respond to this regimen. However, conservative management will prove to be inadequate for a subset of patients. When conservative therapy fails, other noninvasive treatment measures may be considered. Extracorporeal shock wave therapy (ESWT) has been used in soft-tissue disorders including lateral epicondylitis, plantar fasciitis, and calcific tendonitis of the shoulder. Conclusive evidence recommending ESWT as a treatment for Achilles tendinopathy is lacking. This article explores the role of shock wave therapy in the management of recalcitrant Achilles tendinopathy in patients attempting to avoid an invasive intervention.

Abstract
BACKGROUND Functional management of the ruptured Achilles tendon can be effective using orthoses like the removable walker boot (Foam Walker Boot, Air Cast UK Limited, Lincolnshire, United Kingdom). We conducted this study to look at the outcome of our protocol using this orthosis. MATERIALS AND METHODS We retrospectively reviewed 107 non-operatively managed Achilles tendon ruptures over the last 5 years. Case notes were analyzed for demographics and immediate outcomes. Long term outcomes were assessed by a postal questionnaire using the Achilles Tendon Total Rupture Score (ATRS). RESULTS Of the 107 tendons (male:female=71:36, mean age=50 years), 105 tendons (98%) healed with an average discharge time of 22 weeks. Six patients reported major complications and 6 reported minor complications. We received 56 questionnaires with a mean ATRS score of 21. Seventy-seven percent returned to pre-injury level of activity. CONCLUSION Functional management of Achilles tendon rupture, under appropriate supervision, provides a viable option for non-operative management.

Abstract
The Achilles tendon (AT) is the most frequently ruptured tendon in the human body, but the etiology of AT ruptures is still not completely understood. Percutaneous repair and conservative management are viable alternatives to open surgery, which carries higher complication rates and is the most costly of the 3 management options. Individual patients will have different needs due to their age, occupation, or level of sporting activity. If the studies reporting a rising incidence of AT rupture are accurate, the field of AT surgery will become an increasingly important one for orthopedic surgeons. A major problem in the evaluation of the outcome of management of AT ruptures has been the lack of a universally accepted scoring system for the evaluation of results of management of AT rupture. The AT Total Rupture Score is a self-administered instrument with high clinical utility, and it can be used for measuring the outcome, related to symptoms and physical activity, after treatment in patients with a total AT rupture. Future developments may include the use of adhesives in tendon surgery. An understanding of the role, which cytokines play in tendon healing may also lead to the advent of new treatments, possibly based on gene therapy. However, such novel interventions are unlikely to be in routine clinical use for some time.

Abstract
BACKGROUND A number of non-operative interventions are used to manage Achilles tendinopathy. In particular, local glucocorticoid injections have generated controversy. Although a number of case reports indicate symptomatic relief following glucocorticoid injection, one systematic review found little evidence to support their efficacy. Furthermore, local glucocorticoid injections may be associated with rupture of the Achilles tendon. This systematic review considered all available clinical trials measuring the effect of local glucocorticoid injections on symptom relief in patients with Achilles tendinopathy. MATERIALS AND METHODS The search strategy encompassed five databases: Medline, EMBASE, CINAHL, AMED and the Cochrane Library. Only studies reporting the outcome of glucocorticoid injection for Achilles tendinopathy were included. RESULTS A total of 72 articles were identified, five of which met the inclusion criteria. These included one randomized controlled trial, three retrospective studies, and one prospective case series. CONCLUSION There is no consensus as to whether local glucocorticoid injections have a therapeutic role in the treatment of Achilles tendinopathy However, they may incur a risk of tendon damage and therefore further research is required before glucocorticoid injections can be recommended for use in Achilles tendinopathy.

Abstract
The purpose of this study was to design an animal model that induces histological changes in Achilles tendons consistent with those cited in the literature for human Achilles tendon disease. Sprague-Dawley rats were subjected to 10 degrees uphill treadmill running on a custom-designed rodent treadmill and at a speed of 17 meters per minute for 1 h, five times per week, over a 12-week treatment period. Subsequent histological analysis revealed alterations in the rat Achilles tendon that were generally consistent with those described in the literature for diseased human tendon tissues. These features include: decreased collagen fiber organization, more intense collagen staining, and increased cell nuclei numbers. Interestingly, though, immunohistochemical cell typing suggests that the observed increased cellularity does not include a significant inflammatory component but is secondary to increased numbers of endothelial cells (i.e., vascularization) and fibroblasts. These histological features likely represent a biological repair/remodeling response resulting from overuse running.

Abstract
The Achilles tendon is the largest and strongest tendon in the body, yet one of the most commonly injured. Tendon degeneration is a relatively common disorder, predisposing to tears and often associated with paratenonitis. Numerous other diseases involve the Achilles tendon, some with classic imaging appearances, others with non-specific appearances. The aim of this pictorial essay is to review the radiographic, computed tomographic, ultrasonographic and MR appearances of the normal and diseased Achilles tendon.

Abstract
Ailments of the Achilles tendon are on the increase and present in athletic and sedentary patients. The management of tendinopathy and rupture is not codified; Achilles tendon rupture and tendinopathy can be managed conservatively or surgically. Tackling the complications that arise from the management of these conditions provides a formidable challenge to the surgeon. Rupture, rerupture, disordered scarring with potential keloid formation, nerve damage (especially the sural nerve), poor healing, infection, bleeding and hematoma formation, wound dehiscence, deep vein thrombosis (DVT), and loss of function have been reported. This article gives an up-to-date account on our personal views of managing complications following Achilles tendon rupture, tendinopathy, and delayed rupture.

Abstract
Achilles tendinopathy is prevalent and potentially incapacitating in athletes involved in running sports. It is a degenerative, not an inflammatory, condition. Most patients respond to conservative measures if the condition is recognised early. Surgery usually involves removal of adhesions and degenerated areas and decompression of the tendon by tenotomy or measures that influence the local circulation.

Abstract
Achilles tendon ruptures became increasingly common in the latter half of the 20th century. Once the diagnosis is made, the patient's goals and objectives should be clearly stated. The treatment choice should incorporate the patient's needs, desires, objectives, and functional goals to assure an optimal result.

Abstract
Achilles tendon disorders are among the more common maladies seen by sports medicine physicians. Understanding the anatomy and biomechanics of the Achilles tendon and contiguous structures is essential to the diagnosis and treatment of Achilles tendon overuse injuries. Posterior heel pain is multifactorial and includes paratenonitis, tendinosis, tendinosis with partial rupture, insertional tendinitis, retrocalcaneal bursitis, and subcutaneous tendo-Achilles bursitis. Each of these entities is distinct, but they often occur in combination. Although most cases of this disorder are successfully treated nonoperatively, a small subgroup of recalcitrant cases may benefit from surgical intervention. Complete ruptures in active, athletic persons should be treated operatively in most cases and result in predictably good outcomes. There may be some cases that escape early recognition and require a reconstructive procedure to salvage a potentially severe functional deficit.

Abstract
Tendon pathology has many manifestations, from spontaneous rupture to chronic tendinitis or tendinosis; the etiology and pathology of each are very different, and poorly understood. Tendon is a comparatively poorly vascularised tissue that relies heavily upon synovial fluid diffusion to provide nutrition. During tendon injury, as with damage to any tissue, there is a requirement for cell infiltration from the blood system to provide the necessary reparative factors for tissue healing. We describe in this review the response of the vasculature to tendon damage in a number of forms, and how and when the revascularisation or neovascularisation process occurs. We also include a section on the revascularisation of tendon during its use as a tendon graft in both ligament reconstruction and tendon-tendon grafting.

Abstract
Twenty-two heels in 21 patients treated surgically for a primary diagnosis of insertional Achilles tendinosis were reviewed on the basis of preoperative and postoperative examinations, office records, and a comprehensive questionnaire administered to each subject. Each patient underwent surgical treatment using a midline-posterior skin incision combined with a central tendon splitting approach for debridement, retrocalcaneal bursectomy, and removal of the calcaneal bursal projection as necessary. The findings at surgery revealed involvement of the middle third of the insertion in 21 of 22 cases with only one patient manifesting isolated lateral involvement. Thirteen of 22 had an associated prominent calcaneal bursal projection and four of 22 a superficially inflamed bursa. Three patients required reinsertion of the tendo Achilles via drill holes and one underwent augmentation with a plantaris tendon. Operative findings and complications were reported. Eight male and 13 female patients underwent 22 procedures (one case bilaterally) with an average follow-up of 33 months. Preoperative symptoms include presence of symptoms over a range of three months to two years and pain associated with activities of daily living (17 of 22), limitation of regular activities (six of 22), and pain present at rest in six of 22. Postoperatively, 20 of 22 patients were able to return to work or routine activities by three months; only 13 of 22 were completely pain free. Only 13 of 22 also claimed that they were able to return to unlimited activities. Overall, there was an 82% (18 of 22) satisfaction rate with surgery and 77% (17 of 22) stated they would have the surgery again.

Abstract
Extracorporeal shock-wave application facilitates dissolution of rotator cuff calcifications. Therefore, disappearance or disintegration of tendon calcifications by shock waves might be appropriate for any kind of tendon calcification. Here, shock waves with various energy flux densities were applied to the mineralized medial gastrocnemius tendon of turkeys as an animal model. After application of shock waves in vivo, with energy flux density of 0.6 mJ/mm(2), histologic examination and microradiography did not show dissolution or disintegration of tendon calcifications. After shock-wave application in vitro, even for energy flux density of 1.2 mJ/mm(2) neither dissolution nor disintegration of tendon calcifications were observed. Biomechanical testing revealed significant impairment of tensile strength following shock-wave application in vitro, with energy flux density of 1.2 mJ/mm(2), but not with 0.6 mJ/mm(2). These results are important for considerations of clinical extracorporeal shock-wave application on tendon calcifications, as well as on tendon ossifications.

Abstract
Twenty-five patients who had an acute Achilles tendon rupture were managed with an augmented repair using the gastrocnemius-soleus fascia. All patients healed their repair and there were no re-ruptures. There was one infection. Augmented repair allowed early functional recovery as evidenced by full ankle motion by four to eight weeks, full unassisted weight bearing by three weeks, cessation of braces by four weeks, and return to work by one to six weeks post-operatively. Augmentation adds a sufficient amount of collagen to allow early range of motion and weight bearing without re-rupture. Disadvantages included a long incision, soft tissue prominence, one infection, and sural nerve injury.

Abstract
Surgical treatment of posterior heel pain caused by insertional (calcific) Achilles tendonitis or retrocalcaneal bursitis includes resection of diseased tendon or exostectomy. Currently, no guidelines exist to determine how much tendon may be excised without risking rupture of the Achilles tendon. Anatomic dissections revealed the average height of the insertion measured 19.8 mm (range, 13-25 mm). Average width at the proximal aspect of the insertion measured 23.8 mm (range, 17-30 mm) and distally measured 31.2 (range, 25-38 mm). To assess the risk of avulsion, the tendon insertion was partially released in 25% increments of its measured height or width by one of the four methods: (1) from superior to inferior, (2) from the central portion outward, (3) from medial to lateral, and (4) from lateral to medial. Repeated cyclic loading of body weight x 3 was applied, and, if the tendon remained intact, the next 25% increment was released. This process was repeated until failure occurred. Failure occurred in all specimens by an oblique intratendonous separation or shear between the intact portion remaining on the calcaneus and the resected fibers remaining in the clamp. Fibers inserting into the bone did not avulse. Superior-to-inferior resection was found to be superior to the other three methods with eight of nine specimens remaining intact after 75% resection. We therefore conclude that superior-to-inferior offers the greatest margin of safety when performing partial resections of the Achilles insertion, and as much as 50% of the tendon may be resected safely.

Abstract
There are only a few epidemiological studies on the incidence of Achilles tendon (AT) ruptures. These show an increase in incidence in the West during the past few decades. The main reason is probably the increased popularity of recreational sports among middle-aged people. Ball games constitute the cause of over 60% of AT ruptures in many series. The 2 most frequently discussed pathophysiological theories involve chronic degeneration of the tendon and failure of the inhibitory mechanism of the musculotendinous unit. There are reports of AT ruptures related to the use of corticosteroids, either systemically or locally, but the role of corticosteroids in large patient series is marginal. In addition, recent studies do not confirm earlier findings of blood group O dominance in patients with AT rupture. Comparable series have been published with surgical versus nor surgical treatment and postoperative cast immobilisation versus early functional treatment. Although conservative treatment has its own supporters, surgical treatment seems to have been the method of choice in the late 1980s and the 1990s in athletes and young people and in cases of delayed ruptures. Early ruptures in non-athletes can also be treated conservatively. In small series of compliant, well motivated patients, functional postoperative treatment has been reported to be well tolerated, safe and effective. The lack of a universal, consistent protocol for subjective and objective evaluation of AT ruptures has prevented any direct comparison of the results. The results have been often assessed according to the criteria of Lindholm or Percy and Conochie, but no scoring is available for the analysis. We assessed a new scoring method and analysed the prognostic factors related to the results. There is also no single, uniformly accepted surgical technique. Although early ruptures have been treated successfully with simple end-to-end suture, many authors have combined simple tendon suture with plastic procedures of various types. No randomised study comparing simple suture technique and repair with augmentation could be found in the literature. The major complaint against surgical treatment has been the high rate of complications. Most are minor wound complications, which delay improvement but do not influence the final outcome. Major complications are rare, but often difficult to treat with minor procedures. For instance, large postoperative skin and soft tissue defects in the Achilles region can be treated successfully with a microvascular free flap reconstruction. The complications of conservative treatment include mostly reruptures and residual lengthening of the tendon, which may result in significant calf muscle weakness. It has been postulated that a physically inactive lifestyle leads to a decrease in tendon vascularisation, while maintenance of a continuous level of activity counteracts the structural changes within the musculotendinous unit induced by inactivity and aging. Proper warm-up and stretching are essential for preventing musculotendinous injuries, but improper or excessive stretching or warming-up can predispose to these injuries.

Abstract
The risks and benefits of local injection therapy of overuse sports injuries with corticosteroids are reviewed here. Injection of corticosteroid inside the tendon has a deleterious effect on the tendon tissue and should be unanimously condemned. No reliable proof exists of the deleterious effects of peritendinous injections. Too many conclusions in the literature are based on poor scientific evidence and it is just the reiteration of a dogma if all steroid injections are abandoned. The corticosteroids represent an adjuvant treatment in the overall management of sports injuries: basic treatment is 'active' rest and graduated rehabilitation within the limits of pain. With proper indications there are only few and trivial complications that may occur with corticosteroid injections. Guidelines for proper local injection therapy with corticosteroids are given.

Abstract
We evaluated biopsy specimens from the Achilles tendon in 40 patients with long-standing achillodynia and an ultrasonographic widened tendon with hypoechogenic areas. We used a standardized protocol to assess the general tendon pathology score of paraffin-embedded specimens stained with HE. Stereologic measurement of the volume density of glycosaminoglycan (GAG)-rich areas, stained with the Alcian blue (pH 2.5)/periodic acid Schiff method (AB/PAS) was performed. 14 specimens obtained at autopsy served as reference material. Abnormal fiber structure and arrangement, focal variations in cellularity, rounded nuclei, decreased collagen stainability and increased non-collagenous extracellular matrix were seen in all biopsy specimens. Slight histopathological changes were noted in half of the controls. Increased vascularity was present in two thirds of the patient specimens and in one third of the controls, and signs of perivascular hemorrhage, as evidenced by hemosiderin deposition in 6/40 of the patients, but in none of the controls. The volume density of GAG-rich areas was higher in the patients 0.47 (0-0.86) than in the controls 0 (0-0.07). Changes in the fiber structure and arrangement, as well as increased amounts of interfibrillar GAG, appear to be characteristic morphological features in Achilles tendons with long-standing achillodynia and ultrasonographic widening. These findings may indicate that achillodynia is due to local disturbances in connective tissue metabolism or circulation or to both.
