Objective: Functional outcome of Intraarticular Tibial Plateau Fractures fixed with precontoured anatomical plates using Knee Society Score.
Methods: Observational study with retrospective review of collected data. Patient's demography, mechanism of injury, schatzker's classification includingtype IV, V and VI. All patients underwent screw and plate fixation using two incision technique with pre-contoured anatomical plates and intercondylar lag screws where indicated. Passive range of motion exercises started at 2 weeks. Postoperative knee pain, range of motion and stiffness were recorded at followup 3 and 4 months. Mean±SD were calculated for quantitative variables and qualitative variables were presented with frequency and percentages. The association of outcome (Knee Society Score) with gender, age and Schatzker's type was evaluated by applying Fisher's Exact test considering p-value <0.05 as significant.
Results: Twenty-five patients were included in study. 20 patients were available and 05 lost to follow up. 16 were males and 4 females out of 20 patients. Average age is 36.2±12.89 years. All patients sustained injuries after RTA. 5 patients had postoperative knee pain while remaining were pain free. Average flexion was 123.8 with (SD 8.88)range of 105 to 135 degree. Average extension was 3.15 with (SD 2.41) range of 0 to 8 degress. 4 patients developed stiffness of knee. 2 patients symptomatic implant. All fractures healed at follow up at 4 months. According to Knee Society score (SD 7.65) 14 cases scored as good, 4 cases scored fair and 2 cases scored poor. There was no association of knee score was found with gender (p=0.493) but significant association of knee score was found with age (p=0.007) and Schatzker's type (p=0.028).
Conclusions: Tibial plateau fractures can be effectively treated by anatomical reduction and absolute fixation using pre-contoured anatomical plates. Functional outcome calculated by Knee Society score is better in young patients. With appropriate surgical techniques and early post-operative rehabilitation, good functional results can be achieved.
