From Achilles Tendinopathy to Achilles Tendon Rupture: a Comparison between Two Independent Cohorts

(2019) Veldman, A.H.

Introduction: Both Achilles tendinopathy (AT) and Achilles tendon rupture (ATR) are common and increasingly prevalent tendon injuries resulting in functional impairments and prolonged absence from sport participation, with some patients not returning to their previous sporting activities at all. A continuum model from a healthy Achilles tendon to AT to eventually ATR has been proposed. Patient characteristics (demographic, lifestyle and medical) that may influence the progression from AT to ATR are unknown.
Aim: The aim of this study is to compare and contrast the demographic, lifestyle and medical characteristics between patients with AT and patients with ATR.
Methods: In this study a comparison was made between two independent observational prospective cohort studies, consisting of either AT or ATR patients. A baseline questionnaire was used to compare the patient characteristics (demographic, lifestyle and medical) between the AT and ATR cohorts. This baseline questionnaire consisted of questions concerning demographic, lifestyle and medical patient data and was similar in both cohorts. Descriptive statistics were used to present all data. Data were compared between AT and ATR patients using the independent t-test, Mann-Whitney U test, chi-squared test or Fisher-exact test.
Results: In total, 62 patients, 38 AT (13 females; 25 males) and 24 ATR (11 females; 13 males) patients were included in this study. Mean age was similar in both groups (AT 44.4 vs. ATR 39.8 years) (p = 0.15). Mean weight and BMI were 87.6kg and 27.6kg/m2 for AT compared to 79.2kg and 25.3kg/m2 for ATR patients (p = 0.03; p = 0.02). Fewer AT patients (53%) participated in sports compared to ATR patients (83%) (p = 0.016). Median duration of sport activity was shorter for AT than ATR patients (1.0 vs. 3.0 hours/week) (p = 0.015). A total of 25% ATR patients had previous Achilles tendon complaints prior to rupturing their Achilles tendon.
Conclusion: In this study, it was found that more patients with an ATR were active in sports compared to AT patients. A large portion of ATR patients had Achilles tendon complaints prior to ATR. Furthermore, both AT and ATR patients were overweight, with AT patients having a higher body weight compared to ATR patients. This study could not clarify on differences in medication use and comorbidities between AT and ATR patients due to low rates. More prospective studies are needed to investigated the differences in patient characteristics between AT and ATR patients.
