Anterior knee pain in cyclists – either below the kneecap (patella) or underneath it – is commonly referred to as patello-femoral pain syndrome (PFPS). It is one of the most common, affecting more than half of cyclists who suffer from overuse injuries. Of those, approximately 70 percent suffer from recurrent pain, especially if it involves the under-surface of the patella. If not correctly managed this can, over time,lead to osteoarthritis of the patello-femoral joint.
PFPS can arise from various structures around and within the patellofemoral joint. These include the bone, fat pad, quadriceps tendon, patellar ligament, synovium and retinaculum.
