Background: Anterior cruciate ligament rupture thought to be one of the most popular injuries among adults. Knee pain is a common post-operative rehabilitation problem, which may disturb muscle physiological prosperities and hinder the fluence of post-operative rehabilitation milestones achievement and vise versa. Blood flow restriction is an innovative technique which positively affects postoperative knee function.
Purpose: To investigate the effect of adding Blood flow restriction to post-operative anterior cruciate ligament conventional rehabilitation protocol on knee pain.
Methods: Thirty six post-operative anterior cruciate ligament post-operative patients were randomized into two groups. Participants in group I received conventional rehabilitation protocol. Participants in group II received blood flow restriction training added to conventional rehabilitation protocol. Knee pain was evaluated using a visual analogue scale pre-operative and one and half months and three months post-operatively.

Results: There was significant improvement of knee pain on visual analogue scale post-operative at all measures in both groups (p-value<0.05), while there was no significant differences between both groups at post-operative measures (p-value>0.05).
Conclusions: Adding blood flow restriction technique to conventional rehabilitation protocol was not superior to conventional rehabilitation protocol alone on knee pain post anterior cruciate ligament reconstruction
