Long term combined effect of mulligan patellar mobilization and tibiofemoral mobilization in athletes with patellofemoral pain syndrome:a single group experimental study

Patellofemoral pain syndrome is an umbrella term used for pain arising from the patellofemoral joint itself, or adjacent soft tissues. Patellofemoral pain syndrome (PFPS) is a pattern of slowly developing diffused pain in the knee that is typically made worse by standing after sitting, walking, stairs, deep squatting, kneeling, and extended sitting (movie sign). PFPS is one of the most prevalent musculoskeletal disorders in teenagers and young adults, with a reported 25% incidence in the general population.1 It is related to a breakdown in the mechanical forces that operate between the femur and patella. Patients often report diffuse anterior knee pain(AKP) increases the compressive stresses across the patellofemoral joint2 An estimated 7% to 40% of teenagers and active young people suffer from this somewhat prevalent illness that is seen in the clinical setting3 Excessive load or extended repetitive motion in the patellofemoral joint (PFJ) is the cause of this pain and dysfunction. An additional typical cause of PFS discomfort foot problems, knee ligament injuries, and a decrease in the strength of the hip abductors and an increase in the power of the adduction muscles4 Pain persistence or development may be influenced by impairments in soft tissue and joint motion. Hypomobility, for example increasing lateral joint loading during knee flexion, such as a lack of medial PFJ gliding or a decrease in the extensibility of the tensor fascialata, iliotibial tract, or lateral retinaculum. Improper joint loading may continue if mobility limitations are not addressed.5 The patella moves within the trochlea groove, which is controlled by both active and static stabilizers in the patellofemoral joint such as the patellar tendon, quadriceps tendon, and the surrounding soft tissues, such as the iliotibial band, which act as stabilizing forces4 In the general population, reports indicate that the annual prevalence of PFPS is 29% in teenagers and 23% in adults5 It is common for half of PFP patients to have an inaccurate diagnosis of patellar maltracking based on the patella’s lateral translation during complete knee extension6The largest sesamoid bone in the body, the patella serves as a pivot to increase the quadriceps’ mechanical advantage in fully extended knee Because there is a lack of articular congruency, the patella can glide more freely because it does not articulate with the femoral condyles. At 20 to 30 degrees of knee flexion, the femoral condyle is first made touch with the inferior patellar facet. The patella and femoral condyles become more congruent as flexion proceeds, with the largest contact area occurring between 60 and 90 degrees of knee flexion. The patellofemoral joint (PFJ) experiences a significant increase in compressive pressure during weight-bearing duties, even though the contact between the patella and femur increases with knee flexion. According to earlier research, PFJ loads can reach 1.3 times body weight.7 Joint mobilization has been demonstrated to provide a variety of benefits, including bettering pain modulation, reducing broad hyperalgesia, and improving mobility in patients with chronic knee pain. It has also been found to improve psychological outcomes5A prevalent cause of "anterior knee pain," patellofemoral pain syndrome (PFPS) primarily affects young women without obvious pathological alterations in the articular cartilage or an elevated Q-angle.8Many sportsmen restrict their sporting activity due to PFPS symptoms.8Research has demonstrated that youth athletes had enhanced quality of life, increased brain cortical excitability, enhanced long-term neural adaptation mechanisms, and enhanced visuospatial skills. Despite these conclusions, recent research indicates that, in comparison to multisport athletes, sport specialization in female teenagers is linked to an increased incidence of PFPS.9Up to 40% of clinical visits for knee issues and about 25%– 30% of all injuries observed in a sports medicine clinic are said to be related to (patellofemoral pain) PFP. PFP is responsible with 33% and 18% of all knee injuries in athletes that are male and female, respectively. It is also one of the most typical overuse injuries in a variety of sports, including running, basketball, and volleyball. In 74% of patients, PFP symptoms may result in a reduction in athletic participation or the abandonment of sports altogether.10As much as 44% of long-distance triathlete competitors report having knee overuse injuries, making them the most common injury among athletes. When it comes to triathlon athletes, PFPS is perhaps the most prevalent subgroup of overuse knee pain. Physiological overloading with or without "mal-alignment" is a major element in the diverse and multiple etiology.
