Read the detailed description

Patellofemoral pain syndrome is pain around and under the patella (kneecap). The condition is also known as runner's or jumper's knee and affects both kids and adults. It can also occur in one or both knees . Patellofemoral pain syndrome (PFPS) is one of the most common orthopedic knee afflictions among both adults and adolescents. This syndrome, constitutes 5% of all injuries and 25% of knee injuries. It is characterized by pain in the back of the knee cap that comes in contact with the femur , and it is usually aggravated by walking stairs, deep squatting, kneeling, prolonged sitting, and standing up from sitting.

The treatment of PFPS varies from medication and up to different rehabilitation approaches, including balance and proprioceptive exercises to regain normal activities of daily level and optimizing function. Also, the rehabilitation of PFPS includes conservative treatments of physical therapy for symptoms such as muscle strengthening exercises (quadriceps femoris and hip abductors), flexibility exercises (rectus femoris, hamstring, gastrocnemius, hip flexors), foot orthoses to reduce pronated foot, patellofemoral joint taping, braces, and non-steroidal anti-inflammatory drugs (NSAIDs).

Some studies have reported a pronated foot as an intrinsic risk factor for PFPS, suggesting that it may be a solution to the underlying problem. Abnormal motion of the talonavicular joint due to navicular drop or drift in the pronated foot is an indicator of the overall function of the foot. Similarly, studies have shown a correlation between the pronated foot and PFPS. A pronated foot is defined as the flattening or loss of the medial longitudinal arch (MLA). Changes in the lower extremity alignment can cause calcaneal eversion, tibia internal rotation, valgus knee, and femur internal rotation in the normal structure, altering the angle of muscle contraction of the quadriceps femoris, causing the patella to track in the lateral direction, resulting in lower extremity dysfunction.

Foot interventions in patients with patellofemoral pain have shown significant effectiveness of the talonavicular joint mobilization (TJM) to maintain foot posture and to control hypermobility of the talonavicular joint of the pronated foot which will cause changes in PFPS pain, lower extremity function, valgus knee, foot posture. Foot core strengthening: relevance in injury prevention and rehabilitation for runners.

One potential intervention that has gained attention is inguinal ligament mobilization (ILM), a manual therapy technique designed to address pelvic and hip alignment that could indirectly affect knee mechanics. Inguinal ligament mobilization is thought to improve the mobility and function of the surrounding structures, potentially alleviating PFPS symptoms.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. pain intensity

    1.Effect of adding inguinal ligament mobilization to talonavicular joint mobilization on pain intensity in subjects with PFPS. and it is measured by Visual Analogue Scale (100 mm (10-cm) straight line with descriptive anchors at each extreme to measure pain intensity)

    Measured: Inguinal Ligament Mobilization will last 20 minutes, with 2 sessions per week over 4 weeks.Mobilization of talonavicular Two sets of 5 minutes totally for 4 weeks for two sessions per week.conventional physical therapy 2 sessions per week for 4 weeks.

  2. pain threshold

    2.Effect of adding inguinal ligament mobilization to talonavicular joint mobilization on pain threshold in subjects with PFPS. and it is measured by pressure algometer (a handheld diagnostic device used to objectively quantify pain sensitivity by measuring the exact force at which a patient begins to feel pain).

    Measured: Inguinal Ligament Mobilization will last 20 minutes, with 2 sessions per week over 4 weeks.Mobilization of talonavicular Two sets of 5 minutes totally for 4 weeks for two sessions per week.conventional physical therapy 2 sessions per week for 4 weeks.

  3. knee function

    3.Effect of adding inguinal ligament mobilization to talonavicular joint mobilization on knee function in subjects with PFPS. and it is measured by Kujala Patelofemoral Pain Questionnaire (in score from 13-question survey used to measure knee pain, function, and symptoms related to the kneecap. It scores from 0 to 100 points, where 100 means no pain or disability).

    Measured: Inguinal Ligament Mobilization will last 20 minutes, with 2 sessions per week over 4 weeks.Mobilization of talonavicular Two sets of 5 minutes totally for 4 weeks for two sessions per week.conventional physical therapy 2 sessions per week for 4 weeks.

  4. Q angle

    4.Effect of adding inguinal ligament mobilization to talonavicular joint mobilization on Q angle in subjects with PFPS. and it is measured by Goniometer (in angles)

    Measured: Inguinal Ligament Mobilization will last 20 minutes, with 2 sessions per week over 4 weeks.Mobilization of talonavicular Two sets of 5 minutes totally for 4 weeks for two sessions per week.conventional physical therapy 2 sessions per week for 4 weeks.
