Knee arthritis is tricompartmental. In TKR patellofemoral arthritis can't be neglected. However, one group of surgeons always replace patellar surface, other group never touch patella, some replace it in only selected cases. This study was undertaken to see if any difference in functional outcome between two groups Objective; Compare the functional outcome between the patellar resurfaced and non-resurfaced groups and to find out the overall Patient satisfaction in both the groups in total knee

For pain VAS score, for function KSS, HSS scores used.The data was analyzed using the Student t test and Mann-Whitney U test. Results: 57.5% of the overall patients being females and 42.5% being men. 75% of the resurfaced cases were male and 90% of the non-resurfaced cases were female. The mean age of patients was 64.8 years. The mean body mass index was 28.1. The measured intraoperative patellar thickness using a caliper is statistically significant with a mean thickness of 19.7mm in unsurfaced and 23.6 mm in resurfaced group. Conclusion: There is no difference in the overall satisfaction or quality of life between the two groups.
