AbstractIntroduction: Anterior knee pain is one of the common problems in post primary total knee
arthroplasty patients. There are different methods of prevention of anterior knee pain post
total knee replacement. The objective of this study is to compare the efficacy of patellar
denervation using circumferential electrocautery versus non-denervation in relieving anterior
knee pain following primary total knee arthroplasty.
Methods: Forty patients were grouped randomly in to two groups of nineteen patients (Group
A) and twenty one patients (Group B) each. Patients in group A underwent patellar
denervation with electrocautery and group B patients didn’t undergo patellar denervation.
They were followed up at 2 weeks, 1, 2 and 3 months regularly and clinical score was
determined using knee society score and anterior knee grading system by waters and Bentley.
Results: There is no statistical difference in anterior knee pain score between the two groups.
Conclusion: Patellar denervation doesn’t reduce the anterior knee pain following primary
total knee arthroplasty and anterior knee pain was thought to be multifactorial.
