Achilles' tendon tendinitis and heel pain

The clinical diagnosis of Achilles tendinopathy: a scoping review

Background

Achilles tendinopathy describes the clinical presentation of pain localised to the Achilles tendon and associated loss of function with tendon loading activities. However, clinicians display differing approaches to the diagnosis of Achilles tendinopathy due to inconsistency in the clinical terminology, an evolving understanding of the pathophysiology, and the lack of consensus on clinical tests which could be considered the gold standard for diagnosing Achilles tendinopathy. The primary aim of this scoping review is to provide a method for clinically diagnosing Achilles tendinopathy that aligns with the nine core health domains.

Methodology

A scoping review was conducted to synthesise available evidence on the clinical diagnosis and clinical outcome measures of Achilles tendinopathy. Extracted data included author, year of publication, participant characteristics, methods for diagnosing Achilles tendinopathy and outcome measures.

Results

A total of 159 articles were included in this scoping review. The most commonly used subjective measure was self-reported location of pain, while additional measures included pain with tendon loading activity, duration of symptoms and tendon stiffness. The most commonly identified objective clinical test for Achilles tendinopathy was tendon palpation (including pain on palpation, localised tendon thickening or localised swelling). Further objective tests used to assess Achilles tendinopathy included tendon pain during loading activities (single-leg heel raises and hopping) and the Royal London Hospital Test and the Painful Arc Sign. The VISA-A questionnaire as the most commonly used outcome measure to monitor Achilles tendinopathy. However, psychological factors (PES, TKS and PCS) and overall quality of life (SF-12, SF-36 and EQ-5D-5L) were less frequently measured.

Conclusions

There is significant variation in the methodology and outcome measures used to diagnose Achilles tendinopathy. A method for diagnosing Achilles tendinopathy is proposed, that includes both results from the scoping review and recent recommendations for reporting results in tendinopathy.

Athletic injuries

Injuries are common in the various disciplines that make up the sport of athletics. Diagnosis depends on an accurate history and competent examination, possibly assisted by imaging techniques such as ultrasound, magnetic resolution imaging and computerized tomography. It is also important to consider the influence of various intrinsic and extrinsic factors in deciding on the mechanism of injury. Most acute injuries relate to overstretching of soft tissue, whereas overuse injuries reflect repetitive microtrauma with degenerative or inflammatory consequences. Steroid injections should be restricted to situations where inflammation predominates. Surgery may be required for specific acute injuries and when supervised rehabilitation over 6 months fails to resolve chronic injury. Following surgery, physical and psychological rehabilitation should be carefully planned.

Diagnosis and management of the painful ankle/foot part 1: clinical anatomy and pathomechanics

Distinctive anatomical features can be witnessed in the ankle/foot complex, affording specific pathological conditions. Disorders of the ankle/foot complex are multifactoral and features in both the clinical anatomy and biomechanics contribute to the development of ankle/foot pain. The superior tibiofibular, distal tibiofibular, talocrural, subtalar, and midtarsal joint systems must all participate in function of the ankle/foot complex, as each biomechanically contributes to functional movements and clinical disorders witnessed in the lower extremity. A clinician's ability to effectively evaluate, diagnose, and treat the distal lower extremity is largely reliant upon a foundational understanding of the clinical anatomy and biomechanics of this complex complex. Thus, clinicians are encouraged to consider these distinctions when examining and diagnosing disorders of the ankle/foot.

Insertional Achilles tendinopathy

There has been significant progress in our understanding of Achilles insertional tendinopathy since Clain and Baxter divided Achilles tendon disorders into noninsertional and insertional tendinopathy in 1992. In this article we specifically concentrate on Achilles insertional tendinopathy. Classically, overuse and poor training habits are considered to be the main etiology of Achilles insertional tendinopathy. This article discusses Achilles insertional tendinopathy from the anatomy of to its management.

Diagnosis and Management of the Painful Ankle/Foot. Part 2: Examination, Interpretation, and Management

Diagnosis, interpretation, and subsequent management of ankle/foot pathology can be challenging to clinicians. A sensitive and specific physical examination is the strategy of choice for diagnosing selected ankle/foot injuries and additional diagnostic procedures, at considerable cost, may not provide additional information for clinical diagnosis and management. Because of a distal location in the sclerotome and the reduced convergence of afferent signals from this region to the dorsal horn of the spinal cord, pain reference patterns are low and the localization of symptoms is trustworthy. Effective management of the painful ankle/foot is closely linked to a tissue-specific clinical examination. The examination of the ankle/foot should include passive and resistive tests that provide information regarding movement limitations and pain provocation. Special tests can augment the findings from the examination, suggesting compromises in the structural and functional integrity of the ankle/foot complex. The weight bearing function of the ankle/foot compounds the clinician's diagnostic picture, as limits and pain provocation are frequently produced only when the patient attempts to function in weight bearing. As a consequence, clinicians should consider this feature by implementing numerous weightbearing components in the diagnosis and management of ankle/foot afflictions. Limits in passive motion can be classified as either capsular or non-capsular patterns. Conversely, patients can present with ankle/foot pain that demonstrates no limitation of motion. Bursitis, tendopathy, compression neuropathy, and instability can produce ankle/foot pain that is challenging to diagnose, especially when they are the consequence of functional weight bearing. Numerous non-surgical measures can be implemented in treating the painful ankle/foot, reserving surgical interventions for those patients who are resistant to conservative care.

Chronic Achilles tendon overuse injury: complications after surgical treatment. An analysis of 432 consecutive patients

We analyzed the complications after surgical treatment of Achilles tendon overuse injuries in 432 consecutive patients. The patients underwent a clinical examination 2 weeks, and 1, 2, and 5 months after the surgery. If a complication appeared, the patient was followed up clinically for at least 1 year. There were 46 (11%) complications in the 432 patients: 14 skin edge necroses, 11 superficial wound infections, 5 seroma formations, 5 hematomas, 5 fibrotic reactions or scar formations, 4 sural nerve irritations, 1 new partial rupture, and 1 deep vein thrombosis. Fourteen patients with a complication had reoperations: four patients for skin edge necrosis, two for superficial wound infection, two for seroma formation, one for hematoma formation, two for fibrotic reaction or scar formation, two for sural nerve irritation, and one for a new partial rupture. About every 10th patient treated surgically for chronic Achilles tendon overuse injury suffered from a postoperative complication that clearly delayed recovery. However, the majority of patients with a complication healed and returned to their preinjury levels of activity. To reduce this morbidity, it is essential that the surgeon be continuously aware of the possibility of postoperative complications and use proper surgical techniques.
