Vastus Medialis Trigger Points
Symptom Area: Hip, Thigh and Knee
Vastus Medialis Trigger Points are explored here through their location and referred pain pattern. Muscle knots is an everyday term used for tender muscular spots; myofascial pain describes pain involving muscle and its surrounding connective tissue. Extends the knee; oblique fibers (VMO) stabilize the patella medially.
Where you feel it
When the Vastus Medialis holds active trigger points, you usually notice it as anterior knee pain, anteromedial knee pain, buckling knee, medial thigh pain and problems climbing stairs. Where the pain spreads: Medial knee pain that buckles unexpectedly. What often sets it off: Patellofemoral overload, post-surgical disuse.
Overview
Extends the knee; oblique fibers (VMO) stabilize the patella medially. Trigger points here are common in everyday and athletic populations and frequently contribute to the referred pain patterns described below.
Trigger point locations
Anteromedial thigh just above the medial knee.
Referred pain pattern
Medial knee pain that buckles unexpectedly.
Palpation & testing
Palpate the muscle belly along its accessible course. Reproduction of the patient's familiar pain on palpation supports involvement.
Common causes
Patellofemoral overload, post-surgical disuse.
Self-care & clinical treatment
Terminal knee extension, step-down drills. Clinically: needling.
Treatment protocol
For Vastus Medialis, the general protocol applies: sustained pressure release on the taut band, then stretch and active movement in the newly gained range.
Position and palpation: Palpate the muscle belly along its accessible course.
Regional precaution for clinicians: Around the hip and thigh the sciatic nerve behind the deep gluteals, the femoral nerve, artery and vein in the femoral triangle and the adductor canal are the structures to map before treatment.
