“…It generally presents with a gradual onset of pain following exercise, with localised tenderness and nodular thickening of the Achilles typically at the medial aspect of the mid tendon [36]. Insertional tendinopathy presents in athletes with a gradual onset of exercise-related localised pain, tenderness and swelling at the distal Achilles insertion.…”

(2013 AbstractPlantar fascia and distal Achilles injuries are common in elite athletes. Acute athletic injuries of the plantar fascia include acute plantar fasciopathy and partial or complete tears. Underlying most acute injuries is a background of underlying chronic plantar fasciopathy. Injuries may affect the central or less commonly lateral portions of the fascia and acute tears are generally proximal. Athletic Achilles injuries may occur at the mid tendon or the distal insertion, and there may be an underlying chronic tendinopathy. Acute or chronic paratendinopathy may occur as a separate entity or combined with Achilles injury. In this article the spectrum of athletic injuries of the plantar fascia and Achilles is described, illustrated by imaging findings from the London 2012 Olympic games.

“…It should be kept in mind that, the analysis of the experimental research with laboratory animals utilizing the components of the common calcanean tendon, like superficial digital flexor tendon or tendons of the medial or lateral head of the gastrocnemius, are applied to the human calcaneal tendon pathologies only by analogy and not by straightforward translation. Experimental study design should also include the evaluation of anatomical structures which are commonly involved in Achilles tendon related disorders in humans (van Dijk et al 2011). The Kager's (pre-Achilles) fat pad is a lipomatous structure located posterior to the talocalcaneal joint and anterior to the Achilles tendon in a standing man (Ly et al 2004, Theobald et al 2006.…”

In spite of recent advances in treatment protocols, tendinopathies continue to challenge orthopaedists and surgeons. Due to the complexity of both tendon injuries and the healing processes, animal models are essential for addressing fundamental questions in tendinopathy research. Diagnostic imaging could contribute to the evaluation of animal models, thus providing information, which could be translated to human tendinopathies. The objective of our study was to evaluate in situ appearance of the rabbit common calcanean tendon with ultrasonography and magnetic resonance imaging. Additionally, we sought to assess and compare the feasibility and usefulness of these techniques in a rabbit model while focusing on the imaging of the particular structures involved in calcaneal tendon disorders. Eight California rabbits were used for post-mortem sonographic and low-field magnetic resonance examination. Morphometry was performed on longitudinal sonograms and sagittal MRI scans. The craniocaudal diameter of the tendon was measured at four points of interest. Ultrasonography and magnetic resonance provided good visualisation of the tendon origin, the paratenon and the pre-Achilles fat pad. Magnetic resonance images presented in more detail the structure of the calcaneal insertion. Both modalities failed to visualise the individual components of the common calcanean tendon and the bursa of the calcaneal tendon. Statistical analysis of measurements obtained showed that the craniocaudal diameter of the common calcanean tendon in a rabbit increases significantly with a growing length from the calcaneal tuber. Both magnetic resonance and ultrasonography are feasible, and should be considered complementary, not alternative imaging techniques in a rabbit common calcanean tendon model.

“…In contrast, ultrasound shows paratenonitis as a dark hypoechogenic peritendinous halo due to the reduced echogenicity. Once the condition has become chronic, irregularities of the boundary zone of the paratenon can additionally occur and result in significantly increasing hypervascularization in power Doppler [44,45] ( • " Fig. 2).…”

“…In these cases, the bursa often exhibits histological degeneration of the bursal wall -at times with calcification or hypertrophy -and intraluminal fluid collection. In sonography, the fluid-filled bursa appears homogeneously hypoechogenic, while it appears hyperintense in T2-weighted MRI [45]. However, focal hyperintensity of the bursa is not to be primarily evaluated as pathological.…”

“…In addition to the retrocalcaneal bursa, the subcutaneous calcaneal bursa, which is directly subcutaneous and posterolateral to the bony insertion, is frequently also affected. In a pathological state, it appears as an elongated hypoechogenic structure in sonography and as a hyperintense structure in T2-weighted MRI [45] ( • " Fig. 4).…”

In the past decades the incidence of acute and chronic disorders of the Achilles tendon associated with sport-induced overuse has steadily increased. Besides acute complete or partial ruptures, achillodynia (Achilles tendon pain syndrome), which is often associated with tendon degeneration, represents the most challenging entity regarding clinical diagnostics and therapy. Therefore, the use of imaging techniques to differentiate tendon disorders and even characterize structure alterations is of growing interest. This review article discusses the potential of different imaging techniques with respect to the diagnosis of acute and chronic tendon disorders. In this context, the most commonly used imaging techniques are magnetic resonance imaging (MRI), B-mode ultrasound, and color-coded Doppler ultrasound (US). These modalities allow the detection of acute tendon ruptures and advanced chronic tendon disorders. However, the main disadvantages are still the low capabilities in the detection of early-stage degeneration and difficulties in the assessment of treatment responses during follow-up examinations. Furthermore, differentiation between chronic partial ruptures and degeneration remains challenging. The automatic contour detection and texture analysis may allow a more objective and quantitative interpretation, which might be helpful in the monitoring of tendon diseases during follow-up examinations. Other techniques to quantify tendon-specific MR properties, e.?g. based on ultrashort echo time (UTE) sequences, also seem to have great potential with respect to the precise detection of degenerative tendon disorders and their differentiation at a very early stage.
