Patellar tendinopathy is a highly prevalent overuse injury, and most
treatments are only effective to some extent.
This persistence of complaints
could be linked to changed proprioception. One study showed diminished
proprioception in athletes with lateral epicondylitis. Aim of this study was to
determine differences in proprioception, by measuring threshold to detect passive
motion (TTDPM) between recreational athletes diagnosed with patellar tendinopathy
and healthy controls. METHOD: The TTDPM as measure of proprioception was
determined in 22 recreational athletes with patellar tendinopathy and 22 healthy
recreational athletes using a validated instrument. Amount of knee flexion and
extension before the movement was noticed by the subject was determined. 80
measurements per athlete (left and right leg, towards extension and flexion and
with two starting angles of 20 degrees and 40 degrees flexion) were performed.
Mean TTDPM was compared between groups and among the injured recreational
athletes between the affected and unaffected knee. RESULTS: No significant
difference in TTDPM was found between recreational athletes with patellar
tendinopathy and healthy controls. We did find a significant difference between
the injured and non-injured knee in recreational athletes with patellar
tendinopathy; mean TTDPM was 0.02 degrees higher in the injured knee (p=0.044).
CONCLUSION: No difference was found in proprioception between recreational
athletes with patellar tendinopathy and healthy recreational athletes. It is
unclear whether such a small difference in TTDPM between affected and unaffected
knee is important in clinical setting.
