The purpose of this study is to determine if a 10 week exercise rehabilitation program decreases anterior knee oain (PFPS) and improves function in patients with patellofemoral pain syndrome (PFPS). Individuals (age 18-50) with PFPS will be recruited to participate in this study to see if a 10 week exercise program focusing in core and hip strengthening, lower extremity strengthening foot intrinsic strengthening can decrease pain and increase function.

Patellofemoral pain syndrome (PFPS) is a very prevalent condition that presents in great number to patients in physician's offices and has a high recurrence rate. Physical therapy and exercise therapy to strengthen the quadriceps is often prescribed, however recurrence is common. It is hypothesized that PFPS patients have core weakness, hip strength abnormalities and neuromuscular control deficits.

Inclusion Criteria:

• Individuals wishing to participate in study voluntarily
• Subjects diagnosed with patella-femoral syndrome. We will ascertain this by asking a few questions, which will not be recorded as they have not been enrolled in the study yet.
• Capable of following and completing a 10 week home exercise program

Exclusion Criteria:

• Individuals with prior knee surgery, tibial plateau fractures, known diagnosis of knee injuries such as meniscus or ligaments tears.
• Individuals unable to participate, i.e. cognitive deficits, weakness or functional deficits to upper extremities.
• Individuals unable to tolerate exercise program
