Summary

This study looked at whether a 6-week exercise program focusing on hip and ankle mobility could help male soccer players with a common type of knee pain called patellofemoral pain. 48 players were split into two groups: one did the special exercises plus their regular training, while the other only did regular training. The goal was to see if improving joint mobility could reduce pain and improve knee function and performance.
