A variety of surgical procedures exist for repair of both traumatic and degenerative osseous and soft-tissue pathologic conditions involving the foot and ankle. It is necessary for the radiologist to be familiar with these surgical procedures, so as to assess structural integrity, evaluate for complicating features, and avoid diagnostic pitfalls. Adequate interpretation of postoperative changes often requires access to surgical documentation to evaluate not only the surgery itself but the expected timeline for resolution of normal postoperative changes versus progressive disease...

Here, we report the efficacy of the suture bridge technique for treating insertional Achilles tendinosis in an obese and athletic patient. A 48-year-old man presented to our department with a 6-month history of left posterior heel pain. The patient was an athlete (triathlon) and appeared obese (height: 197 cm, body weight: 120 kg, body mass index: 30.9). A diagnosis of insertional Achilles tendinosis was made. Because 6 months of conservative treatments had failed, we performed open resection of the calcaneal exostosis and Haglund's deformity along with debridement of the degenerative tissue of the tendon...

INTRODUCTION: Pain in the Achilles tendon during loading is a very common condition. Conservative treatments, such as low level laser therapy (LLLT) have been reported to give varying results. Recently, a new laser treatment technique, high power laser treatment (HPLT) (Swiss DynaLaser®), was introduced in Scandinavia, but has not, to our knowledge, been systematically tested before. The objective of this study was to evaluate the effects of HPLT compared to placebo HPLT in rated pain and assessed pain threshold in patients with chronic Achilles tendinosis...

The purpose of this article is to report 3 cases of Kager's fat pad scarring and tethering to the deep surface of the Achilles tendon in patients with Achilles tendinosis symptomatology. The 3 patients were diagnosed sonographically by the use of a dynamic maneuver we described and named the "Kager's squeeze" technique. The key finding for diagnosis is the deformation and bowing of the deep fibers of the Achilles tendon during dynamic squeezing of Kager's fat pad. After diagnosis, the patients were treated with ultrasound-guided hydrodissection and scar release to restore normal motion between Kager's fat pad and the Achilles tendon...

BACKGROUND: Abnormalities of the peroneal tendons can frequently be identified on routine MRI of the foot and ankle. Previous studies in the orthopedic literature have discussed the prevalence of abnormal MRI findings in asymptomatic patients, most notably with regards to the spine and shoulder. The purpose of this study was to determine the prevalence of abnormal findings of the peroneal tendons on MRI in asymptomatic individuals. METHODS: We retrospectively reviewed all foot and ankle MRIs from 2 independent time periods that were either performed or reviewed at our institution...

Achilles tendinitis is a common etiology of heel pain, which is a common patient complaint. Achilles tendinitis can be classified into noninsertional tendinosis and insertional tendinitis on the basis of clinical features, radiologic signs, and pathologic findings. Magnetic resonance imaging (MRI) allows classification and reveals associated findings, including retrocalcaneal bursitis, paratendinitis, and paratenonitis. Furthermore, MRI may not only confirm findings of Achilles tendinitis but also diagnose other etiologies of heel pain...

BACKGROUND: Nonsurgical treatments for chronic Achilles tendinopathy (AT) results in unpredictable success rates. Surgical treatment may be chosen as reports show mostly encouraging but variable success rates depending on the pathology. The distribution of surgically confirmed pathologies in AT is largely unknown. PURPOSE: To ascertain the distributions of macroscopically observed anomalies in participants undergoing surgical treatment for chronic AT. STUDY DESIGN: Case series; Level of evidence, 4...

Introduction. Allogeneic amniotic tissue and fluid may be used to treat chronic plantar fasciosis and Achilles tendinosis. This innovative approach involves delivering a unique allograft of live human cells in a nonimmunogenic structural tissue matrix to treat chronic tendon injury. These tissues convey very positive regenerative attributes; procurement is performed with maternal consent during elective caesarian birth. Materials and Methods. In the present investigation all patients were unresponsive to multiple standard therapies for a minimum of 6 months and were treated with one implantation of PalinGen SportFLOW around the plantar fascia and/or around the Achilles paratenon...

BACKGROUND: Subacromial shoulder pain is a common complaint. Radial Extracorporeal Shock Wave Therapy (rESWT) has being increasingly used to treat calcific and non-calcific tendinosis, although there is no evidence of the effectiveness of rESWT in non-calcific tendinosis of the rotator cuff. A randomised single blind study showed that the short-term effect of supervised exercises (SE) was significantly better than rESWT on subacromial shoulder pain, but both groups improved. In a clinical trial on achilles tendinopathy rESWT improved the effectiveness of treatment with eccentric loading...

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...

Achilles tendinosis is a localized degenerative musculoskeletal disorder that develops over a long period of time and leads to a compliant human Achilles tendon. We demonstrate that the compliant Achilles tendon elicited a series of adaptations from different levels of the human movement control system, such as the muscle-tendon interaction, CNS control and other muscles in the lower leg. These results illustrate the human body's capacity to adapt to tendon pathology and provide the physiological basis for intervention or prevention strategies...

This study aimed to characterise the biomechanics of the widely practiced eccentric heel-drop exercises used in the management of Achilles tendinosis. Specifically, the aim was to quantify changes in lower limb kinematics, muscle lengths and Achilles tendon force, when performing the exercise with a flexed knee instead of an extended knee. A musculoskeletal modelling approach was used to quantify any differences between these versions of the eccentric heel drop exercises used to treat Achilles tendinosis. 19 healthy volunteers provided a group from which optical motion, forceplate and plantar pressure data were recorded while performing both the extended and flexed knee eccentric heel-drop exercises over a wooden step when barefoot or wearing running shoes...

Human tendon cells have the capacity for acetylcholine (ACh) production. It is not known if the tendon cells also have the potential for ACh breakdown, nor if they show expression of the nicotinic acetylcholine receptor AChRα7 (α7nAChR). Therefore, tendon tissue specimens from patients with midportion Achilles tendinopathy/tendinosis and from normal midportion Achilles tendons were examined. Reaction for the degradative enzyme acetylcholinesterase (AChE) was found in some tenocytes in only a few tendinopathy tendons, and was never found in those of control tendons...
