Patellofemoral pain syndrome is a prevalent cause of anterior knee pain. Studies show that PFPS is the most common diagnosis in runners and sports medicine clinics. PFPS causes pain during functional activities leading to functional impairments. The cause of PFPS is multifactorial with numerous functional abnormalities of the lower limb.

Physiotherapy rehabilitation following PFPS is a complete set of treating all the causes or the impairments. Conventional therapy, based on strengthening, stretching of a respected group of muscles helps in improving the functional impairments in PFPS. Joint mobilization has been effective in relieving pain. When applied in patients with PFPS, the mobilization with movement [MWM] technique has shown significant results in alleviating pain and improving the restricted range of motion. Previous studies showed that within the first week of application of MWM on the knee joint, used before hip or knee therapeutic activities, provided considerable pain relief and increased functionality in PFPS patients. Previous studies used MWM in open-chain positions which proved beneficial in relieving pain. But there is a lack of literature for using MWM in the closed chain or functional positions.

So, the present study will focus on comparing the effect of MWM in open and closed pack positions.
