Background: The patello-femoral problems are most common cause of morbidity and reoperation after total knee arthroplasty. Methods: Twenty-seven knees in 17 patients who underwent total knee arthroplasty were studied. Eleven knees underwent patellar resurfacing and in 16 knees patella was not resurfaced. These patients were assessed preoperatively and post operatively using knee society scoring system, patellar scoring system and patellar thickness noted. Results: At a mean follow up of 29 months in resurfaced and 17 months in non resurfaced group, statistically significant difference was found, with better patellar scores, stair climbing capacity and lower incidence of anterior knee pain in nonresurfaced group. But the overall knee scores were better in resurfaced group. There was no correlation of anterior knee pain with age, sex, obesity, patellar thickness and range of flexion achieved post arthroplasty. Conclusion: Not resurfacing the patella in mild to moderate osteoarthritic knee especially in obese patients with thin patella gives satisfactory results in total knee arthroplasty.
