There are many different names of diagnosis in knee pain such as IT (iliotial) Band syndrome, patella tracking disorder, patellofemoral pain syndrome, knee arthritis and tendinitis/ tendonitis.
However, it is usually the result of the accumulated tightness of the connective tissues in your knee except traumatic accidents. Once the connective tissues (muscle, tendon, fascia) get tight, it eventually develops trigger points.
The most common cause of knee pain results from trigger points (irritated muscle knots) in Quadriceps muscles.
Please read the trigger point therapy articles ➡️
The most important trigger points to release
1. VL (vastus lateralis) and IT band overlapping area located in the middle third of the femur (Between the knee and hip joint). These trigger points are difficult to find by palpation since it is placed in a deeper layer of VL muscle. The skilled practitioner can feel and release this point by using their elbow. The patient can do self release using the form roller.
2. VL muscle attachment area of the patella bone. This area is located in the lateral corner of the patella bone. You can feel the trigger point by compressing the spot with your finger following the outside corner of the patella bone.
3. General VL muscle and IT band overlapping line (refer to the picture below). When you perform the form roller stretching, you can find and release these sensitive spots.
4. VM (vastus medialis) muscle insertion area (refer to the picture below)
5. Patella tendon. Stress in the patella tendon can cause trigger points in this tendon (refer to the picture). Shockwave therapy can be an effective treatment method.
Patella tracking dysfunction
Tight Quadriceps (VL) and IT band structures generate force pulling the patella bone laterally. The patella bone will be moving laterally (outside) while squatting in standing position. It will result in friction against the trochlear groove and stress on the surrounding tissues. It will lead to wear and tear reaction as well as inflammation in the joint.
