Abstract
Introduction: The jumper’s knee, or patellar tendinopathy, is a common diagnosis in sports and is often invalidating to the athlete with long duration of symptoms and little effective treatment options. For this reason the focus now lies on prevention rather than treatment and therefore causational factors have to be established. A new, scarcely investigated factor is proprioception: the mechanism which senses and corrects the position of the body in rest and during movement. If proprioception in a joint is reduced, so is stability, thereby increasing the risk of injury to the joint and surrounding tissues. A reduced proprioception is established in different injuries, specifically in lateral epicondylitis, which is an injury with comparable causational mechanisms and histopathological findings to the jumper’s knee. The patellar strap is often used by athletes with jumper’s knee to reduce pain, but possibly also has an effect on proprioception by stimulation proprioceptive nerve endings in the skin and knee joint. Therefore, the primary aim of this study was to compare proprioception of the knee between athletes with a one-sided jumper’s knee and healthy controls, and to compare proprioception in these two groups with athletes who had a history of one-sided jumper’s knee. De second aim was to determine if there was a positive effect of wearing a patellar strap on proprioception of the knee. Methods: Proprioception was assessed using threshold to detect passive motion (TTDPM) in 22 healthy subjects, 22 subjects with a one-sided jumper’s knee and 19 subjects with a history of one-sided jumper’s knee. TTDPM was measured on both knees and with or without patellar strap. Results: TTDPM did not significantly differ between the 3 groups. When comparing the symptomatic knee with the non-symptomatic knee there was a significantly higher (worse) TTDPM in the non-symptomatic knee in subjects with a history of one-sided jumper’s knee (TTDPM 0.68° versus 0.61°). This difference was not found in both other groups. TTDPM was significantly lower (0.03°) when wearing the patellar strap, although only in the healthy subjects group and the group subjects with a history of jumper’s knee. In the group subjects with a jumper’s knee there was only a tendency towards this effect (p = 0.072). Conclusion: there was no difference in knee proprioception between subjects with jumper’s knee or a history of jumper’s knee compared to healthy subjects. Wearing a patellar strap improves proprioception of the knee, although the effect is small.
