Patella is the largest sesamoid bone in the body to an integral part of the extensor mechanism of the knee joint. The functional outcome of patella fractures depends on age, severity of injury, treatment modality, anatomical reduction and restoration of articular congruity, post-operative rehabilitation 
. Aim of the study to assess the functional outcome of modified tension band wiring in patella fractures.
Materials and methods: This is prospective study of 32 patients conducted at Basaveshwara Medical College and Hospital over a period of 2 years. All patients with 32 patellar fractures treated by modified tension band wiring. Functional outcome assessed as per the knee pain score, good fellow grading for range of motion. Patients were evaluated at 2nd week, 4th week, 3rd month and 6th months.
Results: Age of patients ranged from 23-65 years with mean age of 40.6 years. Out of 32 patients, 22 (68.75%) patients were male and 10(31.25%) patients were female. Right knee was involved in 20 (62.5%) cases. About 18 (56.25%) cases attained fracture due to indirect trauma. Mean operation time was 90 minutes. Complications like superficial infection were seen in 2 patients. Average duration of hospital stay was 16 days. At the end of 6th month 2(6.25%) patients had ROM <90, 6 (18.75%) patients had 90-120 degree of motion and 24 (75%) patients had > 120 degrees motion. At 6th month follow up 3(9.4%) patients had mild (30-45) knee pain score. Majority of patients show excellent results according to good fellow grading for range of motion.
