Insertional Achilles tendinopathy (IAT) is a frequent cause of posterior heel pain and is often associated with Haglund's deformity. Surgical correction for refractory cases of IAT has been well studied; however, the method of tendon fixation to bone in these procedures remains controversial, and to date, no standard technique has been identified for tendon fixation in these surgeries. Often, after Haglund's resection, there is large exposed cancellous surface for Achilles reattachment, which may require unique fixation to optimize outcomes...

BACKGROUND: The ultrastructural alterations related to tendinopathy have not been well described. Most studies on this subject have been conducted many years ago and focused on material from the Achilles tendon. It was demonstrated that various comorbidities can affect ultrastructural alterations in the advanced tendinopathy, however there is very little data on ultrastructural morphology in tendinopathies related to mechanical overload as in case of the long head of the biceps brachii tendon (LHBT)...

BACKGROUND: Recent investigation of human tissue and cells from positional tendons such as the rotator cuff has clarified the importance of inflammation in the development and progression of tendon disease. These mechanisms remain poorly understood in disease of energy-storing tendons such as the Achilles. Using tissue biopsies from patients, we investigated if inflammation is a feature of Achilles tendinopathy and rupture. METHODS: We studied Achilles tendon biopsies from symptomatic patients with either mid-portion tendinopathy or rupture for evidence of abnormal inflammatory signatures...

PURPOSE AND HYPOTHESIS: Mid-portion Achilles tendinopathy is characterized by a proliferation of small vessels, called neovascularization, which can be demonstrated by power Doppler sonography (PD). Neovascularization can be correlated with diagnosis and consequent therapies focused on vascular supply. Published data regarding the relationship between neovascularisation and symptoms, such as pain and disability, are contradictory. The hypothesis that contrast-enhanced ultrasound (CEUS) could detect with more sensibility than PD the new vessel ingrowth in human degenerated Achilles tendons and therefore the correlation of neovascularization with pain and disability, was evaluated...

The transfer of the flexor hallucis longus tendon or flexor digitorum longus tendon is frequently used for the treatment of posterior tibial tendon insufficiency or chronic Achilles tendinopathy. According to several anatomical studies, harvesting the flexor hallucis longus (FHL) tendon may cause nerve injury. Sixty-eight embalmed feet were dissected and anatomically classified to define the relationship between Henry's knot and the plantar nerves. Two different configurations were identified. In Pattern 1, which was observed in 64 specimens (94...

Rachel J Shakked, Steven M Raikin
Insertional Achilles tendinopathy is a degenerative enthesopathy associated with pain and dysfunction. Nonsurgical management is first attempted for a period of 3 to 6 months and may consist of physical therapy with eccentric training and other modalities. Surgical treatment can be successful with a variety of approaches. A thorough debridement through a midline tendon-splitting approach is associated with high satisfaction rates. Flexor hallucis longus transfer to augment the repair is considered in older, heavier patients or if more than 50% of the tendon was debrided...

Noninsertional Achilles tendinosis is differentiated from insertional Achilles tendinosis based on anatomic location. Tendinosis, as opposed to tendonitis, is primarily a degenerative process and the role of inflammation is believed limited. The etiology of Achilles tendinopathy may include overuse leading to repetitive microtrauma, poor vascularity of the tissue, mechanical imbalances of the extremity, or combination of these elements. There is evidence to support eccentric exercise nonoperative management for patients with noninsertional Achilles tendinopathy...

Disorders of the anterior tibial tendon (ATT) are rare, and relatively few series have been described in the literature. Ruptures of the ATT are more common than tendinopathies of the ATT. For those patients with a tendinopathy, initial treatment may include activity and shoe-wear modifications.

The development of tendinitis and tendinopathy is often multifactorial and the result of both intrinsic and extrinsic factors. Intrinsic factors include anatomic factors, age-related factors, and systemic factors, whereas extrinsic factors include mechanical overload and improper form and equipment. Although tendinitis and tendinopathy are often incorrectly used interchangeably, they are in 2 distinct pathologies. Due to their chronicity and high prevalence in tendons about the ankle, including the Achilles tendon, the posterior tibialis tendon, and the peroneal tendons, tendinitis and tendinopathies cause significant morbidity and are important pathologies for physicians to recognize...

Severe burn causes systemic inflammation and hypercatabolism, resulting in damage to multiple organs distant to the burn site, including the musculoskeletal system. Bone mass and muscle loss have been reported. However, tendon that connects bone and muscle has not been studied in comparable detail. Here we aimed to characterize the molecular and functional changes in Achilles tendon triggered by severe burn. Forty male Sprague-Dawley rats received 40% total body surface area scald burn. Achilles tendons were collected up to 14 days post burn...

Although injury surveillance in athletics is routinely conducted, discipline-specific Achilles and patellar tendinopathy prevalence remains unknown. The purpose of this study was to explore discipline-specific tendinopathy prevalence and identify whether injury-specific risk factors differed in athletes. Elite athletes were recruited and provided information on their sport training including Achilles and patellar tendon pain history. In order to ascertain whether between-discipline differences existed, data were categorized into discipline groups...

Cell-based therapy hold great promise for tendon disorders, a widespread debilitating musculoskeletal condition. Even if the cell line remains to be defined, preliminary evidences have proven that amniotic-derived cells possess in vitro and in vivo a great tenogenic potential. The present study investigated the efficacy of transplanted human amniotic epithelial cells (hAECs) by testing their early regenerative properties and mechanisms involved on a validated ovine Achilles tendon partial defect performed on 29 animals...

Extracorporeal shock wave therapy (ESWT) has shown promising results in treating epicondylitis lateralis humeri and fasciitis plantaris. This study investigates whether the evidence supports ESWT as part of the conservative treatment regime of chronic Achilles tendinopathy. The differences in diagnosing chronic Achilles tendinopathy, the use of different ESWT-machines and the difference in the evaluating methods for pain make it difficult to compare the studies. There is, however, a clear tendency toward ESWT having a positive treatment effect on chronic Achilles tendinopathy at both the insertion and the mid-portion...

Tendon pathologies are a group of musculoskeletal conditions frequently seen in clinical practice. They can be broadly classified into traumatic, degenerative and overuse-related tendinopathies. Rotator cuff tears, Achilles tendinopathy and tennis elbow are common examples of these conditions. Conventional treatments have shown inconsistent outcomes and might fail to provide satisfactory clinical improvement. With the growing trend towards the use of mesenchymal stem cells (MSCs) in other branches of medicine, there is an increasing interest in treating tendon pathologies using the bone marrow MSC...

Within orthopedics, the use of platelet-rich plasma (PRP) has been rapidly increasing in popularity, however, its true effectiveness has yet to be fully established. Several studies find that injecting PRP to the site of injury does not provide any significant benefit with respect to clinical outcomes; however, many others report the contrary. Due to the conflicting evidence and multiple meta-analyses conducted on the topic, a literature review of high-quality evidence on the use of PRP for common orthopaedic conditions was performed...
