Compressive Myofascial Release of the Vastus Lateralis on Lateral Patellar Tracking in Patellofemoral Pain Syndrome

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

Conditions

• Patellofemoral Pain Syndrome

Interventions

OTHER

baseline physical therapy treatment

Group A focuses on pain relief, muscle relaxation, and strengthening. Hot packs and TENS are applied to the lateral thigh and knee for 20 minutes to reduce pain and muscle tension. Hip strengthening exercises include side-lying hip abduction, clam-shells, prone hip extension, bridging, and lunges. Quadriceps exercises involve straight leg raises, prone terminal knee extension, and mini-squats. Each exercise is done in 2-3 sets of 10-15 repetitions, holding stretches for 5 seconds.

OTHER

Compressive myofascial release of vastus lateralis.

The experimental group receives an additional session of Compressive Myofascial Release (CMFR) for the Vastus Lateralis to address lateral patellar tracking in PFPS patients. The patient lies on their side, and the therapist identifies tight areas, applying firm pressure for 20-30 seconds. Deeper pressure is held for 30-60 seconds, followed by 1-2 minutes of cross-fiber friction. The session includes muscle shaking for 30 seconds and stretching the Vastus Lateralis by extending the hip and flexing the knee for 30-60 seconds, repeated 2-3 times. Patient response is documented for progress tracking.
