Comparison of Open and Closed Chain Exercises in Athletes With Patellofemoral Pain Syndrome

Patellofemoral pain syndrome (PFPS) is a common source of knee pain in the physically active population, predominantly in women. The incidence rate of PFPS among athletes is 25 percent, which is higher than that of general population. PFPS is caused by repetitive stress and aggravated in athletes by cycling and running. These symptoms are caused by structural or biomechanical changes of the joint, which becomes exacerbated by activities such as going up and down stairs, sit for a prolonged period, squatting or kneeling, resulting in increased compressive forces in the joint patellofemoral. It is characterized by defused pain in front of knee. Other signs also present are the patellar crepitus, swelling, and joint blockage despite being deemed a multifactorial condition with no single cure, PFPS is commonly attributed to muscular dysfunction, for which conservative rehabilitation is the treatment of choice. Historically, PFPS has been linked to impairments of the quadriceps muscle.
