Runners Knee Patellofemoral pain syndrome
Patellofemoral pain syndrome, often referred to as runner’s knee or anterior knee pain, is a common knee condition characterised by pain around or behind the kneecap (patella). It typically occurs during activities that involve bending the knee, such as running, squatting, going up or down stairs, or sitting for prolonged periods of time with the knees bent. Patellofemoral pain syndrome is often influenced by an imbalance in the forces acting upon the patella as it moves within the femoral groove.
Several factors can contribute to the development of patellofemoral pain syndrome, including overuse, muscular imbalances including weakness or tightness in the muscles around the knee and hip, biomechanical issues, and improper footwear or training techniques.

Treatments
Patellofemoral pain syndrome is treated using a wide variety of methods, and your physiotherapist will be able to identify which treatments would be most effective for you based on your presentation of symptoms.The primary treatment method for patellofemoral pain syndrome is often physiotherapy. Initial goals of physiotherapy will be to alter exacerbating movements or activities, whilst continuing to encourage individuals to remain as active as possible [1]. Studies have found that patients who exercise will generally have an improvement in pain in the short- and long-term, both at rest and with activity, compared to those who do not exercise [2]. Exercises provided by physiotherapists will focus on hip, trunk and knee strengthening through a mixture of single and double leg exercises [3]. Balance exercises, including single leg standing, have also been shown to improve knee control and improve functionality within patellofemoral pain syndrome [4]. Taping may also be applied to the knee, particularly in individuals where the pain may be related to patellar mal-tracking, which may provide temporary pain relief [5]. In individuals who participate in running sports, gait retraining is also important within the rehabilitation process as addressing faulty biomechanical patterns play a significant role in addressing patellofemoral pain. This would be followed by a gradual return to activity or sport as pain decreases [6].
