ABSTRACT
Background: Fractures of patella are common and it constitutes about significant proportion of all skeletal injuries resulting from either direct or indirect trauma
Objective: To evaluate the outcome of inferior pole fractures of patella treated with tension band wiring and resection of avulsed fragment and re-attachment of ligament to patella
Methodology: This was an comparative study, carried out in Department of Orthopaedic surgery of Lahore General Hospital, Lahore from 16[th] June 2012 to 15[th] June 2014. A total of 20 patients were included in this study. These patients were randomly divided into two groups. In Group-A patients were treated with open reduction and internal fixation with tension band wire and in Group-B patients were treated by resection of the avulsed fragment and reattachment of the patellar ligament to the patella. Patients were followed up for surgical site infection and functional outcome at 1[st], 7[th], 15[th], day one month, three months and six months post operatively. Final outcome was assessed by using Bostman criteria. Data entry and analysis was done by using SPSS version 17
Results: Mean age of all 20 patients was 34.20 +/- 12.13 years. Although both treatment groups had statistically same rate of surgical site infection from 1[st] day till 15[th] day post operatively. From 1[st] month till 6[th] months follow up time period none of the patients had surgical site infection in both treatment groups. At 1[st] month and 6[th] month post operatively in Group-B outcome was statistically better as compared to Group-A patients. But at 2[nd] month outcome of patients was statistically same in both treatment groups
Conclusion: Resection of the avulsed fragment and reattachment of the patellar ligament to the patella had good outcome according to the Bostman criteria as compared to open reduction and internal fixation with tension band wire
