IntroductionDiagnosis and treatment of insertional tendinopathy of the Achilles tendon (IAT) remains a challenge. The aim of this study was to assess the influence of pre-operative radiological pathologies on the patient-reported outcomes following open debridement of all pathologies for IAT.Materials And MethodsIn this IRB-approved retrospective correlation and comparative study, patients with pre-operative imaging were identified from the authors' retrospective IAT database comprising of 118 patients. All were treated by a standardized surgical treatment strategy utilizing a midline, transachillary approach and debridement of all pathologies. A total of fifteen radiologic parameters were measured on radiographs (RX) and MRI. The patient-reported outcomes were assessed using the Victorian Institute of Sport Assessment-Achilles questionnaire (VISA-A-G) and the general health questionnaire SF-12 at a minimum follow-up of 12 months. The data are presented as mean ± SD (95% CI).Results88 patients (74.6%) with an average age of 50 ± 12 (47-52) years were included. Radiographs were available in 68 patients and MRI in 53. The mean follow-up was 3.8 ± 1.9 (3.4-4.3) years. The overall VISA-A-G was 81 ± 22 (77-86), the SF-12 PCS 54 ± 7 (52-55), and the SF-12 MCS 52 ± 9 (50-54) points. None of the assessed radiological parameters had a significant influence on the patient-reported outcome following surgical treatment for IAT.ConclusionIn this retrospective correlation study, no significant association was found between preoperative radiographic and MRI radiologic parameters for IAT and postoperative patient-reported outcomes (VISA-A-G and SF-12).© 2021.
