Quadriceps Surgery

The quadriceps paralysis caused by various reasons can be replaced by quadriceps femoris surgery to strengthen the quadriceps muscle strength and correct knee flexion deformity. The hip and knee joints are organically combined. Before performing quadricepsplasty, the muscle strength of the muscles in the lower limbs should be checked in detail to predict the balance of muscle strength in the groups after the operation. For example: when the gluteus maximus is completely paralyzed and the hip joint cannot be stabilized, the operation of quadriceps femoris alone is not effective; in patients with quadriceps paralysis, the contraction of the gastrocnemius muscle is often used to control the overextension of the knee joint to maintain a certain Stable. If gastrocnemius is paralyzed at the same time, the quadriceps femoris surgery will cause severe overextension of the knee. Therefore, when the glutes and gastrocnemius muscles are paralyzed, this surgery should not be used alone. At the same time, if there are serious deformities of the hip, ankle and foot, surgery should be performed after correction. Two groups of muscle transfers are usually used to replace the quadriceps, namely the biceps and semitendinosus, the sartorius, and the fascia lata. The former is more commonly used.
