What are the dynamic stabilizers of the knee, and in what plane do they contribute to stability?
What will be an ideal response?
ANS:
The dynamic stabilizers of the knee are the knee muscles. The quadriceps femoris is primarily responsible for anterior stability, although some contribution to medial-lateral stability is also made through the extensor retinaculum and vastus medialis and lateralis. The hamstrings support the knee posteriorly, along with the gastroc and the popliteus. The muscles that join into the common tendon known as the pes anserinus support the knee medially; these muscles are the gracilis, sartorius, and the semitendinosus. The complex formed by the biceps femoris, popliteus, and the iliotibial band (tensor fascia lata and gluteus maximus) are considered to provide dynamic support laterally.
