Effects of Hip and Knee Exercises on Knee Pain in Young Adult Females With Long-standing Patellofemoral Pain
Patellofemoral Pain Syndrome
About this trial
This is an interventional basic science trial for Patellofemoral Pain Syndrome focused on measuring Patellofemoral pain, PFP, PFPS
Eligibility Criteria
Inclusion Criteria:
- Participants with PFP are required to have current non-traumatic anterior or retropatellar knee pain which they have experienced ongoing or recurrently for a duration of at least 5 years.
- At least two of the following daily activities should provoke knee-related symptoms: prolonged sitting or kneeling, squatting, running, hopping, or stair walking, tenderness on palpation of the patella or double leg squatting.
- Worst pain during the previous week have to be of more than 3 cm on a 10-cm visual analog scale (VAS).
Exclusion Criteria:
- Patients who have sustained a traumatic injury to the hip, knee, ankle or the lumbar spine within the past 3 month will be excluded.
- Other identifiable knee conditions in isolation (that is, not occuring concurrently with PFP. As an example, if the subject has isolated patellar tendinopathy they will be excluded. If the subject has PFP and concurrent pain at the patellar tendon, they will be included).
- Individuals with rheumatoid arthritis, knee joint effusion, self-reported patellofemoral instability, known malign conditions, neurological disease or previously knee surgery will be excluded as well.
- In cases with suspicion of serious pathology a rheumatologist will be consulted.

Active Comparator
Sidelying hip abduction exercise
Sitting knee extension exercise
Participants will be lying on the side with both legs stretched and with their head resting on a pillow. Participants will be allowed to place their hand in front of them to fixate their body and maintain balance. The participants will be instructed to abduct their hip to 45 degrees and return to the resting position afterwards. An elastic band will be used as resistance. This exercise will be applied only on the test limb. A digital metronome will be used to maintain the pace during the exercise. Load: 12 repetition maximum; Nr. of repetition: 12; Nr. of sets: 3; Rest between sets: 120 seconds; Time under tension: 8 seconds; Distribution of load: Concentric (3 seconds), Eccentric (3 seconds), Isometric (2 seconds).
Participants will be seated at the end of an examination couch with the hip and knee relaxed in a 90 degrees angel. Participants will be allowed to place their hands on the side of the couch and the stabilizing foot may have contact with the floor. The participants will be instructed to extend their knee to a 180-degree angle and return to the resting position afterwards. An elastic band will be used as resistance. This exercise will be applied only on the test limb. A digital metronome will be used to maintain the pace during the exercise. Load: 12 repetition maximum; Nr. of repetition: 12; Nr. of sets: 3; Rest between sets: 120 seconds; Time under tension: 8 seconds; Distribution of load: Concentric (3 seconds), Eccentric (3 seconds), Isometric (2 seconds).
