Patients underwent open surgery, percutaneous surgery or non\u2010surgical treatment of Achilles tendon rupture. Both legs underwent plantar pressure distribution and isokinetic measures. Demographic parameters, maximum calf circumference (MCC) and clinical scores (American Orthopaedic Foot and Ankle Society, Achilles tendon rupture score, Hannover) were also evaluated. Complications were not assessed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Peak plantar flexion torque (PPFT) was significantly weaker on the treated side compared to the untreated leg [80.4 \u00b1 29.7\u00a0Nm (mean \u00b1 SD) vs. 92.1 \u00b1 27.4\u00a0Nm, <jats:italic>p<\/jats:italic> &lt; 0.0001]. PPFT and push\u2010off force (POFF) were not different between treatment groups nor was there a leg difference in POFF alone. There was only a weak correlation of clinical scores and PPFT or POFF, respectively. MCC correlated significantly with both PPFT (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> = 0.21, <jats:italic>p<\/jats:italic> = 0.01) and POFF (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> = 0.29, <jats:italic>p<\/jats:italic> &lt; 0.0001). POFF appeared to be a predictor of PPFT (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> = 0.31, <jats:italic>p<\/jats:italic> &lt; 0.0001). Open surgery outperformed non\u2010surgical treatment in terms of centre\u2010of\u2010pressure line (<jats:italic>p<\/jats:italic> = 0.007), torque per muscle volume (<jats:italic>p<\/jats:italic> = 0.04) and relative POFF per body weight (<jats:italic>p<\/jats:italic> = 0.02) and relative in side comparison (<jats:italic>p<\/jats:italic> = 0.03).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Clinical scores do not predict biomechanical outcomes. Clinically measured MCC is a good predictor of PPFT and POFF and can easily be used in clinical practice.
