Anyone can develop patellofemoral pain syndrome. PFPS is more likely to occur in females and athletes, including children and young adults. People can experience PFPS most often when they participate in sports with frequent running, jumping or squatting. Others may experience PFPS if they are walking or sitting for extended periods of time, kneeling or climbing stairs.
The exact cause of patellofemoral pain syndrome is unknown. Several factors may contribute to the development of PFPS, including:
