The aim of the study was to evaluate the role of ultrasonography (US) in the management of jumper's knee. Sixty-two cases of clinically suggested jumper's knee, 52 asymptomatic contralateral knees and 100 asymptomatic knees of healthy middle aged men were examined. In the symptomatic group US was normal in 25 cases, all recovered with conservative therapy. In 31 symptomatic knees the findings were consistent with jumper's knee as a hypoechoic lesion located in the upper insertion of the patellar tendon in 23 cases and in the distal insertion in one case. In 7 cases the lesion was situated in the insertion of the quadriceps tendon. Surgery was performed on 20 knees and in all of them there was a lesion matching the lesion detected by US. In 6 cases US findings were pathologic, but different from jumper's knee. US findings consistent with jumper's knee could not be detected in the asymptomatic group.

We present a new percutaneous ultrasound-guided galactography technique that may be used in patients in whom the conventional technique fails and breast ultrasonography show dilated ducts.
In order to reveal abnormalities in the soft tissue of the anterior part of the knee, caused by protracted mechanical stress, we performed ultrasound studies of both knees of 95 male workers in the carpet-laying and parquet floor trade (group 1). Seventy-three painters (group 2) served as controls. In group I , an anechoic fluid collection was detected in 10 knees, localized in the superficial infrapatellar bursa and in one patient in the prepatellar bursa, whereas there were no cases of fluid accumulation in the controls. A hypoechoic, oval subcutaneous thickening in the anterior wall of the superficial infrapatellar bursa was detected in 35 (18.4%) and 4 (2.7%) knees, respectively. Prepatellar subcutaneous thickening was detected in 45 knees (23.7%) in group 1, but in only 2 knees (1.4%) in group 2. Two knees in group 1 had thickened and inhomogeneous patellar tendons, while one in group 2 had a thickened and 2 both thickened and hypoechoic patellar tendons. We conclude that uitrdsonography is a useful method for the detection of bursitis and soft tissue changes in carpet-layers. Detection of a fluid collection in a bursa does not necessarily denote bursitis of clinical importance, but does signify irritation due to work stress. Patellar tendon pathology is rare among carpet-layers and is probably unrelated to the occupation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
