Duan G, et al. - Researchers undertook this study to find out the risks associated with anterior knee pain (AKP) after primary total knee arthroplasty (TKA). Evidence obtained from this systematic review and meta-analysis included recommendations for using patellar denervation and patellar resurfacing in primary TKA as these strategies were found to be safe and afforded good clinical outcomes in preventing AKP. Exercising caution was recommended when using an infrapatellar fat pad excision since there was an increased risk of AKP at long-term follow-up (>12 months).
