Abstract
Background
Aim of this study is to determine the difference between re-operation rates after conventional Methods of fixation of patella fractures using Metallic implants and novel technique of all suture fixation using Ethibond or fiber tape.
Methods
This is a retrospective comparative analysis involving 62 patients who had a transverse patellar fracture and underwent surgery between January 2013 to December 2021. Selected patients were divided, based on different fixation methods used, into four groups - TBW group, CC screw group, Encirclage group and Suture Fixation Group. Patients were followed till bone union was evident on radiographs. Number of patients in Metallic implant group undergoing repeat operation were compared with the patients who underwent patella fracture fixation using all suture technique. Mean and standard deviation (SD) were calculated for all continuous variables. Mean of the two groups was compared using unpaired t-test.
Results
TBW was the most common method of fixation used in 41(66.1%) patients. 7 patients each underwent surgery using CC screw, Encirclage +/− TBW, and suture fixation respectively. Bone union was seen in about 85% of patients in all the groups suggesting all treatment modalities lead to good fracture healing. 15 patients(36.6%) of patients in TBW group and 3 patients(42.9%) in encirclage group had implant removal because of hardware-related complications (p<0.001). None of the patient who underwent All suture Fixation underwent re-operation.
Conclusion
The results suggest that Suture fixation of patellar fractures is a valid treatment modality giving excellent results with similar bone union rates without any complications.
