Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
More recently, plate fixation has become increasingly more prevalent in the past decade. Initially, this began with small fragment or mini-fragment plates; which progressed to mesh locking plates and now, anatomical locking patella plates. Biomechanical studies have shown greater loads to failure, less fracture gapping or fracture displacement with locking plate fixation compared to TBW. Its low profile construct and round edges may be more tolerable to patients and less prominent than TBW. Furthermore, another possible advantage of plate fixation is the avoidance of quadricep and patellar tendon insertion scarring, as they do not need to be dissected or passed through for fixation as in TBW. This is the first randomized controlled trial comparing anatomical locking plate fixation and conventional tension band wiring for patella fractures to be performed. This study aims to compare the efficacy and safety of these two methods in the treatment of patellar fractures.
