OBJECTIVES: To describe the prevalence and pain location of self-reported patellar tendinopathy and patellar tendon abnormality in a male elite basketball population. DESIGN: Cross-sectional. SETTING: Pre-season tournament. PARTICIPANTS: Sixty male athletes from the Australian National Basketball League. MAIN OUTCOME MEASURES: Self-reported patellar tendinopathy (PT) using the Oslo Sports Trauma Research Centre Overuse Questionnaire (OSTRC). Pain location using pain mapping (dichotomised: focal/diffuse) and severity during the single leg decline squat. Ultrasound tissue characterisation scans of both patellar tendons. RESULTS: Thirteen participants (22.7%) self-reported PT. Only 3 who reported PT had localised inferior pole pain. Thirty athletes reported pain during the decline squat, 15 described focal pain; 10 diffuse pain (5 missing data). Those with diffuse pain had greater years played [Md = 21 (13-24), n = 10 than focal pain (Md = 12 (7-26), n = 15), p = 0.042, r = 0.3]. Bilateral tendon abnormality was found in 45% of athletes and 15% had unilateral tendon abnormality. CONCLUSION: Elite male basketball athletes self-reporting PT had heterogeneity in pain location. When focal pain with loading was used as a primary definition of PT, 'jumpers' knee' was not common in this cohort. This study found that abnormality of the patellar tendon was common and did not correlate with symptoms. Copyright © 2020 Elsevier Ltd. All rights reserved. DOI: 10.1016/j.ptsp.2020.01.012
