Patients suffering from pain in the lower limbs are commonly seen in clinical practice. Pain may be caused by damaged local structures within or around the foot, knee, or hip or may be referred from other sources (such as the lower back and Sciatic nerve).
Sudden onset foot, knee and hip pain often occurs in athletes involved in fast moving change-of-direction sports, kicking sports, contact sports and those sports which involve twisting movements or rapid acceleration and deceleration (such as football, soccer, basketball, netball and skiing). These acute injuries often involve tearing of cartilage tissue or ligaments within the region. One of the most common causes of sudden onset pain in the knee is a meniscal tear or ligament sprain. Gradual onset knee pain often occurs in those patients involved in sports or activities that involve high running loads, repetitive squatting, lunging, jumping, twisting, kneeling or repetitive kicking.
