The authors mention low-dose radiotherapy as an established method for the treatment of plantar heel pain (1). We fully agree with their statement that, while the exact mechanism of action is not yet understood, very good outcomes have been reported in retrospective and prospective studies.

We would like to add that in recent years several prospective randomized trials from Erlangen and Homburg/Saar (Germany)—which the authors regrettably did not mention in their article—on the one hand, provided evidence of the efficacy of radiotherapy in comparison to a very low (placebo) dose (2), and, on the other hand, searched for the optimum dose in two further studies (3, 4). The updated S2-guideline (5) recommends that radiotherapy with a total dose of 3 Gy should be administered in individual doses of 0.5 Gy twice a week.
