Objective: To determine whether high-level athletes with patellar
tendinopathy have diminished knee proprioceptive acuity.
Design: Cross-sectional study.
Setting: University research laboratory (institutional).
Participants: Twenty-one basketball and volleyball players with
patellar tendinopathy (13 men and 8 women; mean age 24.5 6 3.6;
body mass index = 22.5 6 2.0 kg/m2) and an equal number of
athletes without symptoms of patellar tendinopathy injury were
included in this study.
Assessments: Participants underwent knee proprioception assessments
on a single day. Furthermore, age, sex, height, weight, VISAP
(Victorian Institute of Sport Assessment) questionnaire sports
participation, medical history, knee injuries, previous treatment, and
medication were obtained.
Main Outcome Measures: Knee proprioception was evaluated
by assessing sense of resistance, using a weight discrimination
protocol, and joint position sense (JPS).
Results: No significant differences were observed in JPS at 30 and 60
degrees of knee flexion between groups (P = 0.165 and 0.481, respectively).
In regard to the ability to discriminate weight, significant differences
between the 2 groups were found with the tendinopathy group
showing a higher percentage of error (P = 0.009), namely when the set
of incremental weights varied by 10% from the standard weight.
Conclusions: Athletes with patellar tendinopathy have a diminished
perception of force signals required for weight discrimination,
whereas JPS remains unaffected in these athletes.
