Quadriceps Strain

What is Quadriceps Strain?

A quadriceps strain, or pulled quad, is a tear in one of the four muscles at the front of the thigh. These muscles include the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. The quadriceps muscles work together to extend the knee and are crucial for running, jumping, and kicking. Quad strains are common in sports that involve kicking, jumping, and sprinting. They can range from mild (grade 1) to severe (grade 3). The rectus femoris, which crosses both the hip and knee joints, is most commonly injured.

Symptoms

Diagnosis

Diagnosis typically involves: • Medical history and description of how injury occurred • Physical examination to locate pain and assess severity • Palpation to feel for gaps in muscle (complete tears) • Muscle strength testing • Range of motion assessment • X-rays to rule out bone or hip problems • MRI to evaluate extent of muscle damage • Ultrasound for dynamic assessment • Comparison with uninjured leg

Treatment

Treatment varies by grade of strain: • Immediate RICE (rest, ice, compression, elevation) • Avoid activities that stress the quadriceps • NSAIDs for pain and inflammation • Crutches if needed for severe strains • Gentle stretching after initial healing (usually after 48-72 hours) • Progressive strengthening exercises • Physical therapy for moderate to severe strains • Ultrasound therapy to promote healing • Gradual return to activity when pain-free • Prevention through proper warm-up and conditioning • Surgery for complete tears with significant retraction • 4-8 weeks recovery for moderate strains
