Outcomes of Percutaneous Fixation of Patellar Fractures with Arthroscopic Assistance and Cannulated Screws

Background: There are limited reports on the use of arthroscopic-assisted reduction and stabilization for displaced patella fractures. This approach combines the benefits of minimally invasive surgery with strong internal fixation, allowing for quicker rehabilitation. Question/purposes: Does the arthroscopic assisted percutaneous fixation of patella fracture give early improvement in the functional and clinical outcomes of the knee? Patients and Methods: A prospective case series study was conducted including 37 patients. Patients underwent arthroscopic-assisted closed reduction of the fracture with percutaneous screw fixation. Follow-up visits occurred at 2, 6, and 12 weeks, as well as at 6 months. Radiological evaluations were performed to assess fracture reduction and healing. Additionally, pain levels were measured using the visual analogue scale, while knee function was evaluated using the Lysholm Knee Score and range of motion assessments. Results: The mean age of studied group was (39.8 ± 11. 9) years, 54.1% of them were male. All fractures united in a mean period of (8.35 ± 2.09) weeks. There was statistically significant increase in Lysholm score among studied patients at different interval times follow up with mean of (96.2± 2.4) at 6 months. There was highly statistically significant decreased in VAS score (p˂0.001). All patients regained full range of motion with mean of 131.9 ± 21.3 at 6 months. Conclusion: Arthroscopic-assisted reduction and percutaneous screw fixation is an appropriate technique for acute simple patellar fractures without major separation or comminution.
