AB  - INTRODUCTION: Total knee arthroplasty (TKA) is a reliable and widespread solution 
      for knee osteoarthritis treatment, but about 20% of the patients complains of 
      persisting pain. Neuroma formation in the IPBSN (infrapatellar branch of the 
      saphenous nerve) is an undervalued cause of persistent anterior pain after TKA. 
      The aim of this study was to evaluate the effectiveness of the selective neuroma 
      denervation on patients satisfaction and pain improvement. MATHERIAL AND METHODS: 
      Between 2014 and 2020, we evaluated 13 patients suffering from persistent 
      anterior knee pain and numbness after TKA who underwent a surgical neurectomy of 
      the IPBSN. After clinical assessment and diagnosis confirmation, we carried out 
      the surgery. Short Form 12 Health (SF12), Oxford Knee Score (OKS), and Numeric 
      Rating Scale (NRS) have been collected before and after the procedure. After the 
      surgical treatment, the symptom's resolution and patients' satisfaction were 
      attested by the achievement of the Minimal ClinicallyImportantDifference(MCID) of 
      the self-administered patient-reported outcome measures (PROMs). RESULTS: Our 
      results showed a statistically significant improvement (p < 0.05) of patients 
      pain perception (mean NRS improvement -4.2, SD 2.5) and overall satisfaction 
      (with a mean increase in OKS of 14.5 points SD 9.4, and in SF12 of 6.5 points SD 
      4.0). CONCLUSIONS: Hence, our study suggests that selective neuroma denervation 
      may be an effective solution to improve the quality of life of patients who 
      develop this complication after TKA.
