Tibiofemoral Mobilization in Patellofemoral Pain Syndrome

Patellofemoral Pain Syndrome Clinical Trial

Official title: Effects of Tibiofemoral Mobilization in Patients of Patellofemoral Pain Syndrome

Status Completed

Clinical Trial Summary

The aim of this research was to determine the effects of tibiofemoral joint mobilization in patients of patellofemoral pain syndrome. Tibiofemoral joint mobilization effects on pain and Range of Motion (ROM) in knee joint. A randomized controlled trial was done at Lady Reading Hospital Peshawar and Hayatabad Medical Complex Peshawar. The sample size was 52. The Participants were divided into two groups, 26 participants in experimental group and 26 in control group. The study duration was 4 months. Sampling technique applied was purposive non probability sampling technique. Only 25 to 35 years participants with patellofemoral pain syndrome were included. Tools used in this study were Numerical pain rating scale (NPRS), Kujala Score Questionnaire, Goniometer and Algometer.

Clinical Trial Description

Patellofemoral pain syndrome (PFPS) is the most common overuse injury characterized by anterior and peripatellar knee pain, associated with physical activities in Active Daily Living (ADL) such as climbing stairs, squatting, jumping, and running and by sitting with the knees flexed for prolonged periods of time. It mainly affects young women without any structural changes such as increased Q-angle or significant pathological changes in articular cartilage. It mainly affects young women without any structural changes such as increased Q-angle or significant pathological changes in articular cartilage. Patellofemoral pain has prevalence of 23% in adults and 29% in adolescents annually in general population. Its incidence is higher in women as compare to men and is located at 22/1000 person per year. It accounts for 25-40% of all knee complaints in sports medicine. The prevalence of this problem is high because it can occur in patients with a wide range of physical activity levels.

The main symptom of PFPS is anterior knee pain or pain around and behind patella during patellofemoral joint loading activities. The pathophysiology of PFPS is multifactorial. External factors; change in training intensity and frequency, training surfaces and inappropriate shoe wear, while intrinsic factors includes muscle and soft tissue imbalance and malalignment of lower extremity and poor biomechanics of foot. In PFPS patients' dynamic valgus and patellar maltracking is common. Decrease strength of hip abductors, abnormal rear foot eversion can cause dynamic valgus. Further other muscles imbalance is also associated with PFPS i.e. vastus medialis, vastus lateralis, quadriceps, hamstring and iliotibial tract.

Correction of biomechanical imbalance and decreased anterior knee pain as therapeutic exercise has already been shown to be effective in the treatment of PFPS for pain and function. Conservative treatment involves a multimodal physiotherapy approach including patient education, activity modification, neuromuscular electric stimulation on quadriceps, therapeutic ultrasound, biofeedback, exercises for enhancing the activity of Vastus Medialis Obliquus (VMO) muscle, lower extremity-strengthening exercises, and proximal stabilization, stretching exercises on tight structures, bracings, foot orthoses, patellar mobilization and taping techniques. Patellofemoral pain syndrome is treated through conservative methods from long period of time but

tibiofemoral mobilization is not practiced very much while standard mobilization is patellar mobilization, it can be painful to mobilize patella. So the goal of this study is determine the effect of reciprocal joint mobilization i.e. tibiofemoral joint mobilization in patellofemoral joint pain syndrome and enhance the awareness of this in practice.

Literature review A systematic and evidence based search of relevant literature was performed by utilizing PubMed and Google Scholar as search engines. Search term for the initial literature review was patellofemoral Pain Syndrome, Tibiofemoral mobilization, prevalence of patellofemoral pain syndrome, causes of PFPS, pathophysiology of PFPS, treatment option for PFPS, conservative treatment of PFPS, short term effect of Tibiofemoral mobilization, exercise protocol of PFPS. The search was limited to papers in English preferably published since 2010 with full text available. Different studies were available regarding PFPS but limited data were available regarding tibiofemoral mobilization in PFPS.

A consensus statement (2018) on exercise therapy and physical interventions and mentioned that it is recommended that exercise targeting the hip and knee is a key component of management for all patients with patellofemoral pain, particularly when used in combination.

A consensus statement (2016) from the 4th International Patellofemoral Pain Research Retreat, that exercises are best to treat PFPS in short medium and long term goal and also mentioned that instead of only giving exercises of knee alone if combined hip and knee exercises would be given to patient it will show great effect.

The short-term effects of Movement With Mobilization (MWM) and Kinesio Tapping practices performed in addition to the exercises proved to be similar to one another.

The tibiofemoral joint manipulation with exercises for home plane give a successful results in treating patellofemoral pain syndrome.

A systemic review mentioned that the different combinations of Manual Therapy (MT) and physical therapy analyzed in this review suggest that giving more emphasis to proximal stabilization and full kinetic chain treatments in PFPS will help better alleviation of symptoms.

Another study concluded that interventions directed at the lumbopelvic region did not have immediate effects on quadriceps force output or activation. Muscle fatigue might have contributed to decreased force output and activation over 1 hour of testing. ;
