    AbstractThe percutaneous technique of Achilles tendon repair seems to offer satisfactory clinical and functional results, although these results have been evaluated mainly using objective rating scales. Recently, some "subjective" rating scales have been combined to evaluate the results of various surgical treatments. The purpose of the present study was to compare the results of a percutaneous Achilles tendon repair evaluated objectively using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and subjectively using the Medical Outcomes Study, short-form, 36-item questionnaire (SF-36) questionnaire. A total of 17 consecutive patients were treated for acute Achilles tendon rupture using the modified percutaneous Ma and Griffith technique. We reviewed all patients with a follow-up of 24 to 64 months (mean 45.5). At the final follow-up visit, the AOFAS ankle-hindfoot score of each patient was compared with each 1 of the 8 domains of the SF-36 questionnaire, using the parametric Pearson correlation coefficient and the equivalent nonparametric Spearman rho correlation coefficient. The relation between the objective (AOFAS) and subjective (SF-36) results showed a significant correlation (Pearson's correlation coefficient) between the physical functioning (r = 0.597, p = .011) and bodily pain (r = 0.663, p = .004) SF-36 domains, and a nonstatistically significant correlation with the other SF-36 domains. Very similar results were found using the nonparametric Spearman rho correlation coefficient. These results suggest that regarding pain and function, the AOFAS ankle-hindfoot score and SF-36 provide complementary information; therefore, we believe that the SF-36 questionnaire should be used with the AOFAS ankle-hindfoot score for a more complete evaluation of the outcome.Copyright © 2014 American College of Foot and Ankle Surgeons.
