17. The quadriceps muscle group consists of four muscles: the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. These muscles are responsible for extending the knee joint, which allows for straightening of the leg.18. Common injuries that occur at the foot/ankle include:- Ankle sprains: These occur when the ankle is twisted or rolled, causing damage to the ligaments. Onset: Sudden twisting or rolling of the ankle. Signs/Symptoms: Swelling, bruising, pain, and difficulty bearing weight. Treatment: Rest, ice, compression, elevation (RICE), and possibly immobilization with a cast or brace.- Plantar fasciitis: This is inflammation of the plantar fascia, a thick band of tissue that runs across the bottom of the foot. Onset: Gradual onset, often associated with increased activity or weight-bearing. Signs/Symptoms: Pain in the heel or arch of the foot, especially with standing or walking. Treatment: Rest, ice, stretching exercises, and possibly orthotics or shoe inserts.- Achilles tendonitis: This is inflammation of the Achilles tendon, which connects the calf muscles to the heel bone. Onset: Gradual onset, often associated with increased activity or overuse. Signs/Symptoms: Pain and tenderness in the back of the ankle, especially when standing on tiptoe. Treatment: Rest, ice, stretching exercises, and possibly physical therapy.19. Common injuries that occur at the knee include:- Ligament tears: These can occur when the knee is twisted or bent suddenly, causing damage to the ligaments that connect the bones. Onset: Sudden twisting or bending of the knee. Signs/Symptoms: Swelling, bruising, pain, and instability of the knee. Treatment: Rest, ice, compression, elevation (RICE), and possibly immobilization with a brace or cast.- Meniscus tears: These occur when the meniscus, a cartilage structure in the knee joint, is damaged. Onset: Gradual onset, often associated with twisting or bending of the knee. Signs/Symptoms: Pain, swelling, and stiffness in the knee, especially when twisting or turning the joint. Treatment: Rest, ice, physical therapy, and possibly surgery.- Patellar tendinitis: This is inflammation of the tendon that connects the kneecap to the shin bone. Onset: Gradual onset, often associated with jumping or running activities. Signs/Symptoms: Pain and tenderness in the front of the knee, especially when jumping or running. Treatment: Rest, ice, stretching exercises, and possibly physical therapy.20. Common injuries that occur at the hip include:- Hip fractures: These occur when the bone in the upper part of the thigh (femur) breaks. Onset: Sudden, often associated with a fall or trauma. Signs/Symptoms: Severe pain, swelling, and inability to bear weight on the affected leg. Treatment: Immobilization with a cast or brace, and possibly surgery to repair the fracture.- Labral tears: These occur when the labrum, a cartilage structure in the hip joint, is damaged. Onset: Gradual onset, often associated with repetitive movements or overuse. Signs/Symptoms: Pain, swelling, and stiffness in the hip, especially when moving or twisting the joint. Treatment: Rest, ice, physical therapy, and possibly surgery.- Gluteus medius tears: This is a tear in the gluteus medius muscle, which is responsible for hip abduction and stabilization. Onset: Gradual onset, often associated with repetitive movements or overuse. Signs/Symptoms: Pain, weakness, and instability in the hip, especially when standing or walking. Treatment: Rest, ice, physical therapy, and possibly surgery.
