Abstract:
BACKGROUND: Patellar fracture is a common injury in orthopedics. There is no recognized gold standard for the implants. The improvement of the implants and the progress of the technology are the research hotspot in recent years. OBJECTIVE: To review the new progress of internal fixation for patellar fracture, and to explore the principles and advantages and disadvantages of various surgical treatment methods, so as to guide the clinical choice of the appropriate direction of internal fixators. METHODS: Wanfang and China National Knowledge Infrastructure were searched by the first author. The Chinese key words were “patella fracture, classification, biomechanics, internal fixator, internal fixation, complications, prognosis”. Simultaneously, PubMed was searched with the English search terms of “patellar fracture, classification, biomechanics, implants, internal fixation, tendon reconstruction, complications, prognosis”. The retrieval period was from July 2005 to February 2020. A total of 516 documents were retrieved. According to the inclusion and exclusion criteria, 47 documents were selected and summarized. RESULTS AND CONCLUSION: (1) The patellar fracture with knee extension function damage and articular surface damage should be treated by operation. The operation should not only consider the flatness of articular surface, but also consider the separation and displacement trend caused by the traction of quadriceps femoris tendon and patella ligament. (2) There are many kinds of implants for patella fracture, but there is no unified gold standard. (3) Implants for surgical treatment of patellar fracture include steel wire, Kirschner wire, suture, anchor, and steel plate. All kinds of built-in products are improved and innovated continuously.
