Patellofemoral pain syndrome (PFPS), commonly known as runner’s knee, refers to the pain experienced in the front of the knee, specifically around the kneecap or patella. While athletes are commonly affected by this condition, it can also impact individuals who are not actively involved in sports. The discomfort associated with PFPS often poses difficulties in carrying out routine daily activities.
Identifying Symptoms of Patellofemoral Pain Syndrome
One of the primary indications of patellofemoral pain syndrome is a persistent, dull ache in the front of the knee. This discomfort can manifest in either one or both knees. Activities that involve bending the knees, such as squatting, going up or down stairs, running, and jumping, tend to exacerbate the pain. Additionally, individuals may experience pain after sitting for extended periods with their knees bent, such as at the end of a long workday in an office setting. It is not uncommon for cracking or popping sensations to occur in the knee joint after prolonged sitting or when climbing stairs.
Causes of Patellofemoral Pain Syndrome
The origins of patellofemoral pain syndrome are not fully understood, but there are several well-documented factors that contribute to its development. Engaging in sports that involve extensive running and jumping subjects the knees to excessive stress, leading to irritation behind the kneecap. Additionally, injuries such as fractures or dislocations of the kneecap have been linked to patellofemoral pain syndrome. The condition can also arise from poor alignment of the kneecap, which may be caused by muscular issues in the knee and hip. Furthermore, the inward movement of the knee during squatting can contribute to the development of patellofemoral pain syndrome. It is worth noting that individuals who have undergone knee surgery, particularly anterior cruciate ligament repair, are at an increased risk of developing this syndrome.
