“…Despite still uncertain steps of PRP effects, in the short-term the factors released by the platelets most likely lower tissue inflammation and modulate the pain receptors sensibility. 23 Afterwards, PRP favors the cell proliferation with collagen and matrix deposition, as well as tissue remodeling. The final outcome is tissue scar formation, which can help to restore tendon function.…”

Background Computer-aided diagnosis (i.e., texture analyses) tools are becoming increasingly beneficial methods to monitor subtle tissue changes. The aim of this pilot study was to investigate short-term effect of platelet rich plasma (PRP) treatment in supraspinatus and common extensor of the forearm tendinosis by using texture analysis of ultrasound (US) images as well as by clinical questionnaires. Patients and methods Thirteen patients (7 male and 6 female, age 36–60 years, mean age 51.2 ± 5.2) were followed after US guided PRP treatment for tendinosis of two tendons (9 patients with lateral epicondylitis and 4 with supraspinatus tendinosis). Clinical and US assessment was performed prior to as well as 3 months after PRP treatment with validated clinical questionnaires. Tissue response in tendons was assessed by using gray level run length matrix method (GLRLM) of US images. Results All patients improved of tendinosis symptoms after PRP treatment according to clinical questionnaires. Almost all GLRLM features were statistically improved 3 months after PRP treatment. GLRLM-long run high gray level emphasis (LRLGLE) revealed the best moderate positive and statistically significant correlation after PRP (r = 0.4373, p = 0.0255), followed by GLRLM-low gray level run emphasis (LGLRE) (r = 0.3877, p = 0.05). Conclusions Texture analysis of tendinosis US images was a useful quantitative method for the assessment of tendon remodeling after minimally invasive PRP treatment. GLRLM features have the potential to become useful imaging biomarkers to monitor spatial and time limited tissue response after PRP, however larger studies with similar protocols are needed.

“…It is known that a higher mechanical load and training load promote collagen synthesis, which is measurable using SWE [47]. This may explain the higher patellar tendon stiffness in male athletes because of a higher mechanical load due to higher body mass and muscle strength; however, no professional athletes were included in these studies [4,48]. Another explanation could be the effect of female hormones on collagen synthesis.…”

Background: Injuries of the patellar tendon commonly occur as a result of mechanical loading of the tendon during physical activity. Shear wave elastography (SWE) is an established technique for assessing tendon stiffness, and has good interindividual reliability. The aim of this study was to investigate the impacts of physical parameters and different sports on patellar tendon stiffness in professional athletes using SWE. Methods: Standardized patellar tendon SWE was performed in a relaxed supine position with a small roll under the knee (20° flexion) in 60 healthy professional athletes (30 female, 30 male). Multiple linear regression was performed for patellar tendon stiffness including gender, age, body mass index (BMI), and type of sport. Results: Patellar tendon stiffness showed no significant difference between female (3.320 m/s) and male (3.416 m/s) professional athletes. Mean age (female: 20.53 years; male: 19.80 years) and BMI (female: 23.24 kg/m2; male: 23.52 kg/m2) were comparable. Female professional athletes with oral contraceptive (OC) intake showed higher patellar tendon stiffness than athletes without OC intake (3.723 versus 3.017; p = 0.053), but not significantly. Conclusion: In professional athletes, there are no significant differences in patellar tendon stiffness according to gender, age, BMI and type of sport (handball, volleyball, soccer, sprint, hammer throw). Oral contraceptives may not have an impact on patellar tendon stiffness in female athletes. Further studies are necessary.

“…In these two studies, there was a reduction in neovascularization. The explanation for use of PRP in injured tissues is given by their likely ability to provide beneficial hyperphysiological doses of growth factors to the tissue (3,27) . The use of PRP is increasing in order to aid in the repair process in tendons, although its effects are poorly understood and some studies have not observed a better PRP effect when compared to eccentric exercise.…”

Introduction: The tendinopathy is a common dysfunction in athletes, and the number of tendinopathies has increased in the last few years. Regarding tendon lesions, the Achilles tendinopathy is one of the most commons, specially among runners. There are several techniques to treat tendon lesions, such as the eccentric exercise. This exercise is widely used and discussed in the literature. Goal: To carry out a literature review in order to investigate the short and long term effects of eccentric exercise on tendon vascularization and structure in patients with Achilles tendinopathy. Methods: A literature search was performed in the PubMed, Scielo, Lilacs and PEDro databases Results: 13 studies that measure the effects of eccentric exercises in the tendon structure were selected. Conclusion: The studies suggest that eccentric exercise can modify tendon structure in short and long term, reestablishing its healthy structure conditions.
