The patellofemoral pain syndrome (PFPS) is a common cause for anterior knee pain and mainly affects young women without any structural changes such as increased Q-angle or significant pathological changes in articular cartilage. Patellofemoral pain syndrome (PFPS) is the most common overuse syndrome in athletes. Patellofemoral pain is more common among female athletes especially adolescents and young adults. Symptoms include: persistent pain behind the patella or peripatellar. Pain increases on ascending and descending stairs and squatting and prolonged sitting.~Patellofemoral Pain Syndrome (PFPS) is a common musculoskeletal disorder typically occurring in physically active people aged 40 years and younger, causing pain, functional deficits and lower limb weakness. Traditional treatment has been aimed at strengthening the knee, however recent research suggests the muscles around the hip also play an important role in the development and continuity of Patellofemoral Pain Syndrome.~Patellofemoral pain (PFP) is pain in the peripatellar/retropatellar region that aggravates with physical activities such as squatting, stair climbing, running and jumping or sitting for prolonged periods of time. It is the most common source of anterior knee ailment in active adolescents and young adults and is much more prevalent in women than men.~Patellofemoral pain (PFP) is a very common problem in athletes who participate in jumping sports. Several risk factors may play a part in the pathogenesis of PFP. Overuse, trauma and intrinsic risk factors are particularly important among athletes. Physical examination has a key role in PFP diagnosis. common risk factors should be investigated, such as hip muscle dysfunction, poor core muscle endurance, muscular tightness, excessive foot pronation and patellar malalignment.~Studies conducted on core muscle strengthening exercises program for the management of pain in hip, quadriceps region and ankle joint but limited studies were conducted in patient with patellofemoral pain syndrome. There is a need to compare the effectiveness of routine physiotherapy with and without core stability exercises in patient with patellofemoral pain syndrome. This study is intended to determine the effectiveness of core muscle strengthening exercises for the management of patellofemoral pain syndrome.~The spine, abdominal region, pelvis, hips, and proximal lower extremities, are defined as the core of the body. The effects of core muscle strengthening have been proven as an effective method of management in various cases. The knee is the frequently injured joint in core instability with the decreased hip strength. Deficiency in the control of the neuromuscular system of the body's trunk or core may affect the stability of the lower extremity, which can lead to injury in the tibiofemoral or patellofemoral joints.
The purpose of the study is to compare the effects of routine physical therapy with and without core stability exercises on pain and range of motion, in patients with patellofemoral pain syndrome. The spine, abdominal region, pelvis, hips, and proximal lower extremities, are defined as the core of the body. The effects of core muscle strengthening have been proven as an effective method of management in various cases.
