“…Porta et al 45 defined the normal appearance of patellar tendon at SE as a predominance of green pattern at proximal, middle, and distal portions. However the colour scale of sonographer ranged from red to green (red is defined as hard and green as soft tissue), and these results are in contrast with other Authors that found normal tendon to be harder and tendinopathic tendons to be softer 27,31,32 46 . Patellar tendon stiffness was found to be higher in male than female as well as in patients with lower BMI than obese individuals 47 .…”

SummaryBackground: Sonoelastography (SE) is a new ultrasound-based method adopted in an increased number of scientific reports to analyse normal and pathological tendons. The aim of this study is to provide a systematic overview of clinical applications of SE in normal and pathological tendons. Methods: A systematic research of PubMed, Ovid, and Cochrane Library electronic databases was performed according to PRISMA guideline. Two Authors searched and evaluated the articles independently; a third Author was involved to solve any disagreement. The Oxford Level of Evidence (LoE) was used to assess each article. Results. There is an increasing interest in the application of SE in the evaluation of healthy and diseased tendons. Many different tendons are amenable for SE evaluation, such as the Achilles and patellar tendons, rotator cuff, common extensor tendons, quadriceps tendon, and the plantar fascia.Conclusion. SE appears to be a very useful diagnostic tool, in particular in tendon pathology. This is a dynamic examination, provides an immediate evaluation of the tissue elasticity, and may be useful in recognizing tendon abnormalities and in implementing the information available with conventional US. Level of evidence: IV.

“…Further studies investigating the correlation between score changes and imaging changes of different treatment options need to evaluate the potential of SWE. Even though SWE is a relatively new tool in tendon diagnostics, it is already known that asymptomatic tendons are harder than symptomatic ones 46 . In conclusion, increased tendon rigidity during the 6 month follow-up of our study, refutes a single placebo effect of the combined polidocanol and stretching therapy.…”

SummaryBackground: Highly operator-based injection therapy with vasosclerosing and anesthetic polidocanol is used for tendinopathies. This pilot-study evaluates the topical application of polidocanol gel. Methods: Prospective case series. 39 patients with tendinopathies (14 Achilles, 14 patella, 11 wrist extensors) with a symptom duration > 6 months were included. Polidocanol and static stretching were the therapy in the first 2 weeks, while static stretching was continuously performed for 6 months.

The clinical relevance of altered tendon structure in patellar tendinopathy is contested since structural change persists after symptom resolution. The purpose of this study was to explore the relationships between tendon structure and clinical impairments in patellar tendinopathy. In this retrospective, secondary analysis of individuals with patellar tendinopathy (n = 41), tendon structure (thickness, cross‐sectional area [CSA], shear modulus, and viscosity), symptom severity, lower extremity function (counter‐movement jump [CMJ] height), and quadriceps muscle performance (knee extension force and central activation ratio [CAR]) were recorded for the symptomatic limb. Relationships among structure, symptom severity, lower extremity function, and quadriceps muscle performance were examined using sequential regression models. Adjusting for age, sex, body mass index, and pain levels, there were significant positive relationships for thickness (p < 0.001, β = 0.718) and viscosity (p = 0.006, β = 0.496) with CMJ height. There were significant negative relationships between CSA with both CMJ height (p = 0.001, β = −0.538) and CAR (p = 0.04, β = −0.517). This is the first study to demonstrate relationships between tendon structure and lower extremity function or quadriceps muscle performance in patients with patellar tendinopathy. Clinical significance: Since structural changes persist after symptom resolution, addressing these changes may assist in restoring lower extremity function and quadriceps muscle performance.
