Introduction: The total knee arthroplasty (TKA) is a surgery which is operated on the lower limb. The most important reasons of the necessity of reoperation of the patients in this surgery include infections or movement of the implants. One of the approaches which there have been many studies about evaluating its results is resurfacing.

Objective: The purpose of the present study is to evaluate the satisfaction rate (evaluation of the function rate) in the patients who had a TKA surgery with and without resurfacing.

Method and material: This is a Randomized Clinical Trial. After determining the input and output standards, 100 patients who were eligible for the test were selected and brought into the experiment. Then the selected patients brought into trial and then underwent TKA. It is noticeable that the patients were selected randomly were divided into two groups (with and without resurfacing of the patella) and the satisfaction rate of both groups was evaluated.

Result: The data show that there is no significant difference (P-value>0.05) between the averages of Total Post Final Knee and Function Score (156.33±36.56 for ‘without resurfacing’ and 156.78±36.42 for ‘with resurfacing’) and the averages of Total Pre Final Knee and Function Score (33.42±19.01 for ‘without resurfacing’ and 34.02±25.03 for ‘with resurfacing’). Also the results demonstrate no significant correlation between Post Pain standards and these groups (P-value>0.05).

Conclusion: This study indicates that resurfacing the patella does not affect the satisfaction of the studied patients and improvement of the studied variables comparing to patella without resurfacing.
