Clinical Trial Summary

The Depuy Synthes Locking Compression Plate (LCP) Variable Angle Patella Plating System is an FDA approved device. The purpose of this study is to see how well the Depuy Synthes LCP Variable Plating System work in fixing a broken kneecap (patella). Depuy says that the device will improve healing when compared to traditional ways of repairing a broken patella. The goal of this randomized control trial is to learn how well the LCP Variable Plating System works to fix a broken patella (kneecap) compared to traditional fixation methods, in male and females, age 18 to 74, with a patellar fracture, and being treated at Hartford HealthCare The Bone and Joint Institute or Hartford Hospital. The main question it aims to answer are: - To understand if the Depuy Synthes LCP Variable Angle Plating System will provide a better way to help patients recover from a broken patella. Participants will evaluated at specific time points: post-op day 1, 6 weeks, 3 months, 6 months, and 12 month post-surgery. Participants will be asked to: - Complete surveys at all evaluation timepoints. - Have x-rays(radiographs) taken at the 6 week, 3 month, 6 month, 9 month, and 1 year timepoints. - Participants will have a passive range of motion tests done at 6 week, 3 month, 6 month, 9 month, and 1 year timepoints. - Participants would have strength and balance tests done at the 3 month, 6 month, 9 month, and 1 year timepoints.

Secondary Radiographs Radiographic imaging will be taken at each of the study visits starting at week 6 to assess healing and ensure that there are no issues with the hardware. Radiographic healing will be assessed by the congruity of the cortical bone and reduction of fracture lines. Radiographs will also be used to determine if there is any failure of the hardware. (i.e. loosening of the screws or wires or instrument breakage). 6 weeks

Secondary Passive Range of Motion (ROM) Passive ROM will be assessed at each study visit starting at 6 weeks. Knee flexion and extension will be measured using a goniometer (an instrument that measures angles of joints). Participants will be asked to sit with their hips at 90° and lower leg hanging off the exam table or chair. The center of the goniometer will be placed at the rotational axis of the knee joint and the two arms of the goniometer will be aligned with the femoral shaft and tibial shaft. The participant's leg will then be maximally flexed and the goniometer read to determine the total flexion range, and then the participant's leg will be straightened to determine the maximum extension angle. The total knee arc of motion will be recorded as the addition of these two angles. 6 weeks

Secondary Strength Quadriceps muscle strength will be assessed starting at each visit starting at the 3 month post-operative visit. Strength measures will be assessed using a hand held dynamometer (a device that measures force). The strength assessment will be performed with the participant in a seated position with hips at 90°. The dynamometer will be placed mid tibial shaft and the testers other hand will be placed just above the knee to provide stability. The participant will be instructed to try to straighten their leg against the resistance of the examiner. The strength measures will be repeated 3 times for consistency. Additionally, the strength of the non-injured quadriceps will also be assessed to determine if there is a side to side strength deficit. 3 months

Secondary Balance Balance assessments will also take place at each visit starting at the 3 month post-operative visit. Static balance will be assessed using a portable force plate. Participants will be asked to perform four balance tasks. The first will be with both feet together hands on their hips staring straight ahead. The second assessment will be both feet together, hands on their hips with their eyes closed. The final two assessments will be single limb stances with eyes open. One single limb stance will be used to assess the operative limb the other the non-operative limb. Each balance task will be measured for 20 seconds. During this time investigator will record the medial lateral weight shift, anterior posterior weight shift, and sway area, a 90% elliptical fit of the weight shift with the minor and major axes defined as the maximum and minimum sway values in anterior/posterior and medial/lateral directions. 3 months
