OBJECTIVETo investigate the effects of different treatments for different patella fractures, and analyze the clinical outcome.

METHODSOne hundred and sixty-four patients with patella fracture were treated between July 2005 and December 2009, 113 males and 51 females with an average age of 38.5 years old, ranging from 21 to 72 years. There were 21 cases of linear fracture or separation of the patella < 0.5 cm, 63 of patella separation > 0.5 cm and for the pure horizontal type or vertical-type fractures, 34 cases were separated into three block, 46 cases were separated into four and above. Of 164 cases, 21 patients accepted traditional treatment, 39 patients were fixed with cerclage wire and tension band wire, 43 with cannulated screws and tension band wire fixation, 29 with cannulated screws for the minimally invasive treatment, 32 patients with fixation of NT-PC RESULTS: One hundred and sixty-four cases were followed up with a mean period of 14 months (3 to 36 months). By Lysholm knee score criteria: 19 cases in traditional treatment were excellent and good, 36 cases in cerclage wire and tension band wire technique cases were excellent and good, 40 cases in cannulated screws and tension band wire fixation, 27 cases in cannulated screws for the minimally invasive treatment were excellent and good, 30 cases in NT-PC were excellent and good.

CONCLUSIONThe surgery should be avoided if the patients can be treated with manipulation and fixation. Those who need surgical treatment should be based on the type of fracture to select a different surgical operation. Percutaneous reduction can be fixed, and try to minimally invasive surgery. Whether traditional treatment or internal fixation, the appropriate functional exercise need to make as early as possible.
