Knee pain ranks as the third most frequent issue addressed in physical therapy clinics. While ACL (anterior cruciate ligament) tears often receive significant attention in media and sports, they are relatively rare outside competitive athletics, with approximately 100,000 to 200,000 ACL tears annually in the United States. In reality, these injuries make up only a small portion of physical therapy cases. Arthritis of the knee, including those requiring total knee replacements due to severe pain, is a prevalent condition treated by physical therapists. Additionally, the term ‘anterior knee pain’ encompasses various issues such as patellofemoral pain (kneecap pain) and tendinitis (jumper’s knee).
