Rectus femoris tendinopathy is an often overlooked sports injury. The rectus femoris muscle has two distinct origins:
• The direct head with its insertion on the anterior inferior iliac spine.
• The indirect head with its insertion on superior acetabular ridge.
Tendinopathy of the indirect head may present like FAI, however unlike 'True FAI' this tendinopathy responds fairly well to manual therapy specifically if you target external and internal rotators of the hip along with hip flexors.
