The problems caused by Trigger Points can easily be diagnosed as a ligament or meniscus injury, tendinitis, bursitis and often arthritis. It is amazing how often this knee pain, which can be so debilitating can also be so easily eliminated using Deep Tissue Release.
The thigh is anatomically speaking a huge muscle with four “heads” (technically called quadriceps). It covers the front of the leg, the lateral and part of the medial side, and attaches below the knee via a tendon. The kneecap is embedded in this tendon and depends on it for the free and correct movement of the knee.
The existence of Trigger Points in any of the quadriceps can cause intense pain in the knee and inhibit or distort movement in this whole area. Trigger Points in these muscles can be one of the primary sources of knee pain.
The following is a brief description of the four quadriceps and their symptoms when affected by trigger points:
RECTUS FEMORIS: Covers the front of the leg and flexes the hip and extends the knee.
Symptoms: The trigger point close to the groin causes pain under the kneecap. It can feel like insects crawling or a pricking pain. Other trigger points can cause intense pain above the kneecap which can make the knee feel weak or stiff.
VASTUS LATERALIS: The biggest of the quadriceps. It covers the outside of the leg and is the most common source of knee pain. It has five common trigger points.
Symptoms: Hip pain and lateral thigh pain. The pain can be so intense that one cannot lie on that side. It can send pain behind the knee, walking can be painful since it pulls the kneecap to the side and can cause the knee to lock. Immobilizing it in this case can make it worse.
VASTUS MEDIALIS: This is the one that forms the lump above the inner knee. It pulls the kneecap medially.
Symptoms: Can cause the knee to buckle suddenly. Can cause pain in the inside of the leg and below the inner knee. Trying to stretch or exercise it can make the problem worse.
VASTUS INTERMEDIUS: Below the Rectus Femoris, in the middle of the thigh.
Symptoms: Pain while walking, especially going up stairs. Combined with trigger points in the calf muscles it can cause weakening and sudden buckling of the knee.
