Study Summary

Patellofemoral Pain Syndrome is a prevalent condition characterized by anterior knee pain, often exacerbated by activities such as squatting, running, and stair climbing. This condition is frequently associated with improper patellar tracking, particularly lateral displacement, which can be influenced by various factors including muscular imbalances and tightness. The vastus lateralis muscle, part of the quadriceps group, is often implicated in contributing to lateral patellar tracking due to its attachment and alignment. Compressive myofascial release (CMFR) is a therapeutic technique aimed at reducing muscle tightness and restoring optimal muscle function. This study will explore the effects compressive myofascial release on the vastus lateralis in improving patellar tracking in patients diagnosed with Patellofemoral Pain Syndrome.The methodology of this study involves a randomized controlled trial with a sample of patients diagnosed with Patellofemoral Pain Syndrome. Non-probability convenience sampling technique will be used and participants will be recruited in groups after randomization. Participants(n=26) will be divided into two groups: the intervention group (n=13) receiving compressive myofascial release on the vastus lateralis, and a control group receiving(n=13) a routine treatment. The intervention will be administered over a period of four weeks, with sessions occurring three times weekly. Patellar tracking will be assessed using q-angle analysis both pre- and post-intervention. Additionally, subjective measures of pain and functional ability will be evaluated using the Numeric pain rating scale (NPRS) and the Kujala Patellofemoral Score. Data analysis will focus on comparing the changes in lateral patellar displacement and patient-reported outcomes between the two groups to determine the efficacy of compressive myofascial release in correcting lateral patellar tracking and alleviating symptoms of Patellofemoral Pain Syndrome. SPSS version 25 will be used for data analysis

Study Description

Patellofemoral pain syndrome (PFPS) is one of the most common health-related complaints in today's societies. PFPS refers to a syndrome that comprises of the following signs and symptoms: anterior knee pain, inflammation, imbalance and instability. About 50% of the non-specific knee pain is diagnosed as PFPS. PFPS frequently becomes chronic, and patients cannot do physical activity. Individuals with PFPS typically report pain that is either located in the peri-patellar or retro-patellar region during active movements involving knee movement.

Myofascial pain syndrome (MPS) has been attributed as the main cause and primary source of musculoskeletal pain in 30-85% of the patients attending physical therapy clinics. Myofascial pain syndrome often presents in the forms of pain, muscle spasm or TrP. TrP has been described as a hyperirritability spot located in a taut band of muscle; or a small pea or rope-like nodular or crepitant (crackling, grating) area within the muscle, which is painful to palpation or compression and refers pain, tenderness, or an autonomic response to a remote area. It is stated that "jump response" is elicited when pressure is applied to a Trp. TrP may result from mechanical overload, trauma, overuse, postural faults, or psychological stress. Based on their primary functions, muscles are categorized as "phasic" or "postural" muscles. In response to dysfunction or overuse, the phasic muscles tend to be inhibited or weakened; while the postural muscles tend to develop higher tone and ultimately shorten. A muscle imbalance between the dynamic and postural muscles may lead to MTP in the musculoskeletal system.
