“…It has been suggested that the size of the hypoechoic tendon area may be linked to the amount of pain [11]. Our results support the notion that symptomatic patellar tendons have greater volume or size, as reflected by greater CSA, width and thickness; however, these morphological changes were not associated with clinical features.…”

“…It has been found that structural changes observed on ultrasound imaging can be associated with an increased risk of developing symptoms [9]; nevertheless, tendon pain is not always associated with the presence of abnormal findings on imaging studies [10]. In fact, there is a limited relationship between tendon imaging pathology and presence of symptoms since structural tendon changes can exist in the absence of symptoms, and symptoms can be present without the presence of imaging changes [11]. However, ultrasound imaging continues to be used as a confirmatory tool for a diagnosis of patellar tendinopathy.…”

Imaging findings in patellar tendinopathy are questioned. The aim of this pilot study was to characterize ultrasound measures, by calculating ultrasound ratio and neovascularization of the patellar tendon in non-elite sport players with unilateral painful patellar tendinopathy. Cross-sectional area (CSA), width, and thickness of the patellar tendon were assessed bilaterally in 20 non-elite sport-players with unilateral painful patellar tendinopathy and 20 asymptomatic controls by a blinded assessor. Ultrasound ratios were calculated to discriminate between symptomatic and asymptomatic knees. The Ohberg score was used for characterizing neovascularization. We found that non-elite sport players with patellar tendinopathy exhibited bilateral increases in CSA, width, and thickness of the patellar tendon compared to asymptomatic controls (Cohen d > 2). The ability of ultrasound ratios to discriminate between painful and non-painful patellar tendons was excellent (receiver operating characteristic, ROC > 0.9). The best diagnostic value (sensitivity: 100% and specificity: 95%) was observed when a width ratio ≥ 1.29 between the symptomatic and asymptomatic patellar tendon was used as a cut-off. Further, neovascularization was also observed in 70% of non-elite sport players with unilateral patellar tendinopathy. A greater CSA ratio was associated with more related-disability and higher tendon neovascularization. This study reported that non-elite sport players with painful unilateral patellar tendinopathy showed structural ultrasound changes in the patellar tendon when compared with asymptomatic controls. Ultrasound ratios were able to discriminate between symptomatic and asymptomatic knees. Current results suggest that ultrasound ratios could be a useful imaging outcome for identifying changes in the patellar tendon in sport players with unilateral patellar tendinopathy.

“…The incidence of patellar tendinopathy of player group was 15.79% (6 knees) but only one knee was reported to be symptomatic (IKDC score 49), which indicated that most patellar tendinopathy revealed by ultrasonography in this group is asymptomatic. Fazekas et al surveyed 31 collegiate athletes involved in jumping movement, 13 of them were male and 9 knees were tested positive of ultrasonographic findings of patellar tendinopathy, but the correlation of positive image findings with the scoring of Victorian Institute of Sport Assessment Questionnaire for Patellar Tendinopathy (VISA-P) was poor and insignificant [26]. Our investigation also showed similar result.…”

Basketball is a popular sport worldwide with a high injury risk. In this study, we conducted survey composed of clinical symptom reporting scale, physical examination and meticulous portable musculoskeletal ultrasound to 19 elite male high school basketball players and 15 regular male high school students. Our study showed the incidence of ultrasonographic findings of any lesion, suprapatellar effusion and proximal patellar tendinopathy is significantly higher in player group, and the incidence of asymptomatic ultrasonographic lesion is also higher in player group. Screening for asymptomatic lesions bares clinical relevance and plays a role in prevention of symptom development. With the concise and easy-to-perform ultrasonography protocol we performed and being interpreted by sports team physician, the protocol can offer precise diagnosis of common injury and screening for asymptomatic lesion potentially progressive.

Jumper’s knee is highly prevalent condition in athletes. Very limited evidence is available on clinical effects of tendon dry needling. Therefore, the objective of this study is to compare the effects of ultrasound-guided dry needling (UG-DN) combined with conventional physical therapy and conventional physical therapy alone in patients with jumper’s knee. A total of 96 patients with pre-diagnosed jumper’s knee were randomly assigned to experimental group (UG-DN + CPT) and conventional group (CPT alone) with 48 participants each. Pain intensity and functional disability were recorded using visual Analogue Scale (VAS), Victorian Institute of Sports Assessment-Patellar Tendinopathy (VISA-P) questionnaire, Lysholm Scale, Knee Injury and Osteoarthritis Outcome Score (KOOS) respectively at baseline, at 1st, 2nd, and 4th week. Whereas ultrasonographic features of patellar tendon were measured through musculoskeletal ultrasound (MSKUS) at baseline and 4th week. Total 8 sessions of treatment were provided. Mann Whitney U test and Friedman test were used to compute between and within group differences respectively. P value was significant at 0.05. Results showed that patients in both groups had improvement in signs of jumper’s knee but the improvement in UG-DN + CPT group was more significant (p ≤ 0.05). Significant difference was seen after 4 weeks of intervention in UG-DN + CPT group in VAS (Median ± I.Q.R = 3 ± 1, p = 0.000), VISA-P (Median ± I.Q.R = 83.5 ± 7, p = 0.000), KOOS (Median ± I.Q.R = 83.5 ± 8, p = 0.000), , Lysholm (Median ± I.Q.R = 84 ± 5, p = 0.000) than CPT group VAS (Median ± I.Q.R = 1.5 ± 1, p = 0.000), VISA-P (Median ± I.Q.R = 92 ± 2, p = 0.000), KOOS (Median ± I.Q.R = 92 ± 3, p = 0.000), Lysholm (Median ± I.Q.R = 92 ± 4, p = 0.000) and ultrasonographic features of jumper’s knee were more significant in experimental group(p-value ≤ 0.05). The Ultrasound guided dry needling with conventional physical therapy of patellar tendon had been found an effective treatment for jumper’s knee and helps in reducing pain intensity, improving function and ultrasonographic features in patients with jumper’s knee. UG-DN + CPT group showed more significant results as compared to CPT.Trial registration: (IRCT20210409050913N1). Dated: 17.04.2021.
