About this trial

Patellofemoral Pain Syndrome (PFPS) is a frequent cause of anterior knee pain in young, physically active individuals, especially females, and is commonly managed with quadriceps and hip-focused exercises. However, the role of neural factors has been largely overlooked. The saphenous nerve, which supplies sensation to the anteromedial knee, may become irritated or entrapped and contribute to pain and neuromuscular dysfunction in PFPS. This study suggests that manual therapy targeting the saphenous nerve could improve pain, function, and balance, providing a more holistic approach to PFPS rehabilitation.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

None

Disqualifiers

Knee replacement

An intraarticular injection within the past 3 months

Previous operative treatment or arthroscopy, other secondary knee-related problems (bursitis, tendinopathy, osteochondritis, neuromas, intraarticular pathology (such as osteoarthritis), tumor, and rheumatologic diseases

Diabetic neuropathic pain or fibromyalgia

Trial design

Design model

Parallel

Treatments tested in this trial

  • Saphenous nerve release

    Other intervention

    With the patient lying supine and the leg extended, a tender area is identified on the medial side of the thigh, approximately four to five fingerbreadths above the knee. This area corresponds to a longitudinal fascial strip located behind the sartorius muscle. The therapist places the fingers on either side of this strip and applies a gentle separating force in proximal and distal directions to mobilize the tissue and reduce sensitivity.

Function

Kujala Anterior Knee Pain Scale (AKPS) for knee pain and function, The Kujala score is composed of 13 multiple choice questions: the presence of a limp, the need for support, the ability to walk, the ability to climb stairs, the ability to squat, the ability to run, the ability to jump, prolonged sitting with knees in the flexed position, the presence of knee pain, the presence of knee swelling, the presence of abnormal painful patellar movement, atrophy of the thigh muscles, and deficiency of knee flexion.

Time frame
up to 6 weeks

Secondary outcomes

Q angle

The Q-angle is the angle formed between a line from the anterior superior iliac spine (ASIS) to the center of the patella and a line from the center of the patella to the tibial tuberosity. It reflects the alignment of the quadriceps muscle and the patellofemoral joint and is commonly assessed in patients with PFPS. Kinovea can be used to measure the Q-angle accurately by placing visual markers on the ASIS, patellar center, and tibial tuberosity, then capturing a frontal-plane image or video. Using Kinovea's angle measurement tool, the two lines are drawn and the angle is calculated. This provides a valid, reliable, and non-invasive method for assessing Q-angle in clinical and research settings, particularly for evaluating lower-limb alignment in PFPS.
