This study will utilize T1-Rho MRI to evaluate the effect of intramedullary nailing on patellofemoral articular cartilage when the surgery is performed using the infrapatellar vs. the suprapatellar approach. Subjects will be randomized to one or the other standard care surgical approaches.

Condition Intervention
Acute Tibial Fracture Requiring Intramedullary Nailing
Procedure: Intramedullary nailing of the tibia

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Patella Femoral Changes Following Tibial Nailing: Does Approach Matter?

Further study details as provided by University of Pennsylvania:

Primary Outcome Measures:
  • T1Rho MRI to quantify patellofemoral cartilage changes after IM nailing of the tibia as a primary treatment for acute tibial fractures. [ Time Frame: Up to 6 months post-discharge ]
    The difference in proteoglycan content of patellofemoral articular cartilage as quantified using spin lattice relaxation in a rotating frame (T1ρ MRI weighted image) at 6 months post-hospital discharge between two groups randomized to undergo either a suprapatellar or infrapatellar approach to tibial IM nailing.

Secondary Outcome Measures:
  • SF-36 [ Time Frame: 6 months post discharge ]
    The difference in quality of life outcomes (Medical Outcomes Study: 36-Item Short Form Survey) at 6 months post-hospital discharge between two groups randomized to undergo either a suprapatellar or infrapatellar approach to tibial IM nailing.

Estimated Enrollment: 20
