Clinical Scorecard: Utilization of Cannulated Screws with Tension Band and Cerclage Fixation Techniques for Displaced Patellar Fractures According to Fracture Morphology Classification

At a Glance

Key Highlights

• Both fixation techniques achieved bony union in all cases.
• No significant differences in healing time or complications between the two groups.
• Modified cross cannulated screws had higher operation time and blood loss compared to parallel screws.
• Böstman scores improved significantly post-surgery in both groups.

Guideline-Based Recommendations

Diagnosis

• Operative fixation is recommended for patellar fractures with articular surface displacement greater than 2 mm.

Management

• Utilize cannulated screw tension-band fixation for displaced patellar fractures.

Monitoring & Follow-up

• Follow-up for fracture healing and assessment of complications.

Risks

• Potential complications include fracture nonunion, intra-articular adhesion, post-traumatic arthritis, loss of fixation, and symptomatic hardware.

Patient & Prescribing Data

Patients with fresh displaced patellar fractures.

Cannulated screws provide superior bone purchase and lower risk of implant loosening compared to Kirschner wires.

Clinical Best Practices

• Consider cross screw insertion for comminuted fractures where parallel screw placement is difficult.
• Ensure restoration of a smooth articular surface to prevent complications.
