Core tip: Total knee arthroplasty (TKA) has been shown to be a successful procedure for treating patients with osteoarthritis, and yet approximately 5%-10% of patients experience anterior knee pain (AKP). To prevent AKP after TKA it is important to first identify the different anatomical structures that can cause this pain. Greater attention to and understanding of AKP should lead to significant pain relief and greater overall patient satisfaction after TKA. This article is a review of what pain is, how nerve signalling works and what is thought to cause AKP after a TKA.
