Keywords:Anterior Knee Pain , Intramedullary Nail , Tibia Fracture
Anterior knee pain is a common complaint of patients who have an intramedullary nail inserted for treatment of a tibia fracture. Proposed reasons for anterior knee pain include nail prominence, insertion site, placement of skin incision and approach for insertion relative to the patellar tendon. This study will compare the incidence of anterior knee pain associated with different approaches for insertion of an intramedullary nail for tibia fractures. A parapatellar approach with the nail inserted with the knee in relative extension ("semi-extended") will be compared to a traditional approach with the nail inserted with the knee in flexion. Patients who were treated with an intermedullary nail from February 2008 (date when parapatellar approach initially used at this institution) to the present will be sent a modified Lysholm Knee Scale Score to determine the subjective incidence of knee pain. Scores will be compared among the two groups (semi-extended vs. flexed) to assess differences in anterior knee pain. Conclusions will be drawn as to the efficacy of the semi-extended parapatellar approach for tibial nailing in regards to anterior knee pain.

Inclusion criteria for the patient population under study consists of both male and female adults, at least 18 years old, who have a tibia fracture that was treated with an intramedullary tibial nail using the semi-extended parapatellar approach.
Exclusion criteria for the patient populations consists of those who have:
1. Prior operations about the knee (ipsilateral).
2. Neurovascular compromise.
3. Patients who were non-ambulatory.
