BACKGROUND: It is becoming increasingly apparent that the plantaris can contribute to symptoms in at least a subset of patients with midportion Achilles tendinopathy. However, the nature of its involvement remains unclear. PURPOSE: To determine whether excised plantaris tendons from patients with midportion Achilles tendinopathy display tendinopathic changes and whether the presence of such changes affect clinical outcomes. STUDY DESIGN: Case series; Level of evidence, 4...

Insertional and non-insertional Achilles tendinopathy is usually treated conservatively. Surgery is indicated if conservative treatment fails to relieve the pain. Endoscopic surgery has the advantages of less morbidity, a shorter operating time, reduced postoperative pain, and a lower rate of wound and soft-tissue healing problems. Patients will have a short recovery time and quickly resume work and sports because of less soft-tissue disruption. Moreover, the pathology can be better differentiated and precisely treated...

The Achilles tendon (AT) consists of fibers originating from the soleus muscle (SOL), which lies deep, and the medial (GM) and lateral (GL) heads of the gastrocnemius muscle, which lie superficial. As the fibers descend toward the insertion of the AT, the individual subtendons twist around each other. The aim of this study was to investigate the twisted structure of the AT and its individual subtendons. Specimens of the AT, with preserved calcaneal bone and a fragment of the triceps surae muscle, were obtained from 53 fresh-frozen, male cadavers (n=106 lower limbs)...

BACKGROUND: There is no consensus regarding the treatment of Achilles insertional tendinopathies. Eccentric training remains the main choice in the conservative treatment of this illness; however, the good results in the management of non-insertional Achilles tendinopathy were not replicated in the insertional condition. Low energy shock wave therapy has been described as an alternative to these patients, but has yet to be empirically tested. HYPOTHESIS: Shock wave therapy, adjunctive to the eccentric strengthening protocol, will improve measures of pain and function...

Tendinopathies of the foot and ankle result in substantial impairment of the mobility of patients and have a high clinical significance. Knowledge of the origin of these diseases has been accumulated over decades from the multitude of intrinsic and extrinsic triggering factors based on biomechanical considerations with an evidence-based medicine (EBM) level 5. A high correlation between tendinopathy and hypervascularization of the Achilles tendon was found in a double-blind randomized prospective study using Doppler ultrasound (EBM level 1) but these results were not reproducible; therefore, the importance of these findings is unclear...

Although of several studies that associate chronic hyperglycemia with tendinopathy, the connection between morphometric changes as witnessed by magnetic resonance (MR) images, nanostructural changes, and inflammatory markers have not yet been fully established. Therefore, the present study has as a hypothesis that the Achilles tendons of rats with diabetes mellitus (DM) exhibit structural changes. The animals were randomly divided into two experimental groups: Control Group (n = 06) injected with a vehicle (sodium citrate buffer solution) and Diabetic Group (n = 06) consisting of rats submitted to intraperitoneal administration of streptozotocin...

OBJECTIVES: Hip control affects movement and muscle firing patterns in the leg, ankle and foot, and may contribute to overuse injuries. Muscle performance can be measured as strength, endurance or muscle activation patterns. Our objective was to systematically review whether hip muscle performance is associated with leg, ankle and foot injuries. DATA SOURCES: A structured and comprehensive search of six medical literature databases was combined with forward and backward citation tracking (AMED, CINAHL, EMBASE, Medline, Scopus and SportDiscus)...

Tendinopathy is a common condition, which has been linked to surrogate measures of sympathetic nervous system (SNS) activity and insulin resistance. This study aimed to compare in vivo measures of the SNS and insulin resistance between individuals with and without Achilles tendinopathy. This case-control study compared Achilles tendinopathy sufferers to healthy controls. SNS activity was quantified using muscle sympathetic nerve activity (MSNA), while metabolic status was assessed via a modified glucose tolerance test and fasting lipid panel...

Insertional Achilles tendinopathy is a frequent cause of pain and performance impairment of the ankle. It is more common in runners, but may also affect general population. Conservative treatment is the gold standard in the early phases but 10% to 30% of patients require surgery. The aim of this study is to review the current literature in order to evaluate current surgical strategies for Insertional Achilles tendinopathy and to analyze the effectiveness of the available techniques. We performed a systematic review of the literature, to identify studies reporting clinical outcome after surgical treatment for Insertional Achilles tendinopathy in any population group with at least 6 months follow-up...

BACKGROUND: Insertional Achilles tendinopathy and retrocalcaneal bursitis is difficult to treat, and several operative techniques have been used after failure of conservative management. Dorsal wedge calcaneal osteotomy has been described for the treatment of insertional Achilles pathology. It was hypothesized that dorsal wedge calcaneal osteotomy would be an effective and safe method for the treatment of athletes with insertional Achilles pathology unrelieved by nonoperative measures...
