Knee pain can be caused by disease or injury. The most common disease affecting the knee is osteoarthritis. Knee injuries can occur as the result of a direct blow or sudden movement that strains the knee beyond its normal range of movement. Knee pain caused by an injury is most often associated with knee cartilage tears, such as meniscal tears, or ligament tears, such as anterior cruciate ligament tears.
Lateral collateral ligament (LCL) sprain occurs when the ligament on the outer side of the knee is overstretched. Collateral ligament knee injuries make up about 25% of severe knee injuries in the United States. They most often occur in adults aged 20-34 years and 55-65 years. LCL sprains mainly happen during sporting activities, including contact and noncontact sports, and affect women and men equally. A physical therapist treats LCL sprains to reduce pain, swelling, stiffness, and any associated weakness in the knee or lower extremity.
If you have low back pain, you are not alone. At any given time, about 25% of people in the United States report having low back pain within the past 3 months.In most cases, low back pain is mild and disappears on its own. For some people, back pain can return or hang on, leading to a decrease in quality of life or even to disability.
Lower extremity stress fractures are a relatively common injury seen most often in athletes playing sports that require repetitive impacts (running and jumping). Stress fractures make up about 8% of all activity-related injuries of the lower extremities. Female athletes are about one-third more likely to develop stress fractures in the legs and feet. While athletes may be more susceptible to these types of injuries, individuals who walk, march, or spend much of their workday on hard floors are also at risk. A physical therapist can help with recovery after a stress fracture as well as identify potential risk factors for prevention of future stress fractures.
