Patellofemoral pain syndrome (PFPS) is one of the most commonly diagnosed conditions among adolescents and adults with knee complaints, accounting for approximately 25% of knee disorders diagnosed in sports medical clinics. While the etiology of PFPS is suggested to be multifactorial, several contributing factors such as lower knee extensors strength, quadriceps imbalance, weak hip abductors and overuse have been identified.
Individuals with age 20-40Years
Pain rating > 3 and < 7 on NPRS
Patella alta confirmed with ISI (Insall Salvati index) ratio > 1.2 on lateral knee radiograph
Positive Ely's test for rectus femoris tightness
History of patellofemoral dislocation
Knee osteoarthritis
Recently undergo to surgery to knee
Fracture in knee region
Parallel
Conventional Traetment
Other interventionTENS applied for 10 minutes, Therapeutic ultrasound,Hip abductors and lateral rotators strengthening, Hamstring muscle passive stretching, Isometrics for quadriceps, given thrice a week for 4 weeks .
Muscle Energy Technique and Patellar Inferior Glide
Other interventionMuscle Energy Technique for Hamstrings and Quadriceps While the patient contract muscle (Hamstring / Quadriceps) the therapist applies a gentle controlled force. After the contraction patient release and the therapist reposition the leg into a new barrier. Intensity of contraction will be 20-25-% of maximum strength. Each contraction will be held for 5-7 seconds, followed by additional passive stretching maintained for 30 and the relaxation patellar inferior glide applied at patella: the examiner applied a gentle downward force on the patella with their right hand, while the left hand controlled the direction of the patella's movement. This will be applied for 3-4 minutes as tolerated by the patient.
Numerical Pain Rating Scale (NPRS)
The Numeric Pain Rating Scale (NPRS) is perhaps the most frequently applied scale used to quantify pain intensity in the clinical setting. It is an 11-point numeric scale, ranging from 0 indicating no pain to 10 indicating worst pain imaginable
Universal Goniometer
Universal goniometer (UG) is commonly used as a standard method to evaluate range of motion (ROM) as part of joint motions.
Kujala Anterior Knee Pain Scale (AKPS)
The Kujala patellofemoral scoring system is a tool used to assess the functional ability of the knee joint, specifically in relation to patellofemoral-related issues. This scoring system ranges from 0 to 100, with higher scores indicating better knee function and less pain, while lower scores indicate greater dysfunction and more severe pain.
