Bottom Line: The differences were not significant (p > 0.05 each).This observation was more frequent in male than in female participants (p < 0.05).Acute physical stress is significantly associated with hypervascularity of the patellar tendon.

ABSTRACT

Background: The impact of physical exercise on joints and tendons is still a matter of debate. The aim of this study was to investigate with ultrasound the acute effects of extreme physical exercise on knee and ankle joints and their surrounding structures in trained athletes.

Methods: Participants of the Munich marathon were examined by arthrosonography before and after long distance running. Ultrasound assessment included grey scale and power Doppler examination of the knee and talocrural joints with surrounding tendons. Findings consistent with joint effusion, tendon and/or entheseal pathologies were documented. In addition to the ultrasound evaluation, information on training habits and past or present arthralgia or joint swelling was gathered.

Results: One Hundred Five runners completed both the pre- and post-excercise ultrasound assessments (baseline and follow-up), resulting in the sonographic evaluation of 420 knee and talocrural joints. At baseline, 105 knee (50) and 38 talocrural joints (18.1) showed effusions, compared to 100 knee (47.6) and 33 talocrural joints (15.7 %) at follow-up. The differences were not significant (p > 0.05 each). Effusion size did not correlate with the timepoint of ultrasound assessment and was independent of covariates such as gender, age or running distance. Hypervascularity of the patellar tendon was detected in 21 cases (10.0 %) at follow-up in contrast to one at baseline (p < 0.001). This observation was more frequent in male than in female participants (p < 0.05).

Conclusions: Acute physical stress is significantly associated with hypervascularity of the patellar tendon. No significant changes of synovial effusion were detected in knee and talocrural joints.

Mentions: The size of joint effusion of knee and talocrural joints did not correlate with the time point of assessment, i.e. pre- versus post-running. Changes of joint effusion of knee and talocrural joints and of patellar tendon hypervascularity correlated weakly but significantly with changes of the respective contralateral side (r = 0.33, p = 0.007, r = 0.40, p < 0.001, and r = 0.34, p = 0.001, respectively). No significant correlation was found for changes of joint effusion of the knee with changes of joint effusion of the dependent talocrural joint or vice versa (Fig. 2).Fig. 2
