Round 1
Reviewer 1 Report
Respected Authors,
I congratulate you all for your contribution to the scientific community. After reading the manuscript, I feel that this version of manuscript must be enhanced. Eventhough the quality of the content, especially in the literature review, method, results, discussion, and conclusion are good, the way they are presented to the readers are quite complicated.
In several places I noticed that the scentences are long, extending more than 3, 4 lines. In order to understand that, I had to re-read it multiple times. Such long sentences can be broken down to simple sentence. Eventhough the concept and aim of this manuscript is simple, the way it is presented might make the readers to get exhausted.
Apart from few minor grammer corrections and loooong sentences, this manusript shall be accepted for publication.
Regards.

Reviewer 2 Report
Dear Authors,
It is my pleasure to review your study but I have a lot of doubts.
General information:
-references could be newer
Introduction:
-line 47: "Patellofemoral pain (PFP) is the most common cause of knee injury in runners " to state that it is the most common, please provide newer reference.
-line 51: Its etiology is still not 51 fully understood and has been described as multifactorial" please describe it more precisely.
-Patellofemoral pain (PFP) should be accurately described, symptoms etc.
M&M
- line 115: "...or had knee pain related to running" and line 122 "PFP diagnosis is clinical, based on clinical history and physical examination, and does not require imaging tests". imaging diagnosis was not performed, and if the pain was caused by bone changes? Osteoarthritis? e.t.c. This very important.
-the inclusion and exclusion criteria should be described in more detail.
-"Frontal plane knee projection angle" did all participants have the same shoes? foot defects? this could have influenced the measurements
Results
-you should change commas to dots in numbers (in tables 1-3)
Discussion
-references could be newer.
-it is worth mentioning Patellofemoral Pain Syndrome.
